HI i got a little Problem i have whish list script which adds artivcles from shop into a session and saves them but when i click on the which list he only adds the first item how to male it dynamic that every wish list click is for the individual item in the shop
my article structure, onclick of wlbutton1 or wlbutton2 he should add the article with id1 or 2 to the wishlist:
echo '<div class="span3 filter--'.$obj->product_prop1.'" data-price="'.substr($obj->price, 0, -3) . '" data-popularity="3" data-size="s|m|xl" data-color="pink|orange" data-brand="'.$obj->product_brand.'">';
echo '<div class="product">';
echo '<div class="product-img featured">';
echo '<form method="post" action="../cart_update.php">';
echo '<div class="picture"><img src="images/'.$obj->product_img_name.'">';
echo '<div class="img-overlay"><button class="add_to_cart btn more btn-primary">Kaufen</button>...mehr</div>';
echo '</div>';
echo '</div>';
echo '<div id="result"></div>';
echo '<div class="main-titles"><h4 class="title">'.$currency.$obj->price.'</h4>';
echo '<h5 class="no-margin isotope--title" id="product'.$obj->id.'">'.$obj->product_name.'</h5>';
echo '<p class="no-margin pacifico" style="position: absolute;right: 10px;top: 5px; text-transform: capitalize;">'.$obj->product_brand.'</p>';
echo '<p class="no-margin" style="position: absolute;right: 10px;top: 25px;"><a class="wl-button'.$obj->id.'"><i class="icon-gift"></i></a></p>';
echo '</div>';
echo '<p class="desc">'.substr($obj->product_desc, 0, 160) . '...</p>';
echo '<input type="hidden" name="product_qty" value="1" />';
echo '<input type="hidden" name="product_code" value="'.$obj->product_code.'" />';
echo '<input type="hidden" name="type" value="add" />';
echo '<input type="hidden" name="return_url" value="'.$current_url.'" />';
echo '</form>';
echo '</div>';
echo '</div>';
My Jquery Code how to make it dynamic and individual for eacht artivle?:
$(".wl-button").click(function() {
var wlproduct = $('#product').text();
var wlproducturl = $('#producturl').attr('href');
$.ajax({
type : "POST",
url : "../assets/wlscript.php",
data : { wlproduct : wlproduct, wlproducturl : wlproducturl },
success : function(data) {
$('div#result').text('You added '+wlproducturl+' '+wlproduct+'\'s to your wishlist.');
}
});
});
Here an example of how you can do to find the data you need to add your article.
First the HTML example :
<div class="products">
<form>
<p>
<!-- Fist article -->
<span>Article 1</span>
<!-- A name construct so that I can easilly find in which iteration of the loop I am -->
<input type="hidden" name="article[0].id" value="1" />
<input type="hidden" name="article[0].name" value="article1" />
<button class="addButton">Add article</button>
</p>
<p>
<!-- Second article -->
<span>Article 2</span>
<input type="hidden" name="article[1].id" value="2" />
<input type="hidden" name="article[1].name" value="article2" />
<button class="addButton">Add article</button>
</p>
<!-- … others articles -->
</form>
</div>
And the Javascript part :
$(document).ready(function(){
$(".addButton").on("click", function(event){
event.preventDefault();
var button = $(this);
var parent = button.parent(); // We need to find the container in which to seach our fields.
var idArticle = parent.find("input[name$='.id']").val(); // Find the ID
var nameArticle = parent.find("input[name$='.name']").val(); // Find ather data
alert("Add article with id = " + idArticle + " and name = " + nameArticle);
// Next step is the ajax method to call the server with the correct data.
});
});
By working like that, you can then send to your server the data you need to add an article to your wishlist.
Here the link to the JS Fiddle example.
In this example, you can see how to work around the HTML content from the button to find the inputs.
You can find more about "tree traversal" with the jQuery API.

I'm with an e-learning project and working on the section of massive matriculation. I use a search box to look for students´ name, and add those values to a list. The problem appears when I try to look for other students' name and add those values to the existing list. This part reloads and all the previous values disappear. How can I display the result of new values and add them to the chosen list without removing the old one.
Code to display list (detail.php)
<p>
<label> <?php echo $string['LBL_PROGRAM_NAME']; ?>: </label>
<input type="text" id="program_name" name="program_name" class="tam1" maxlength="200" value="<?php echo $program_name; ?>" />
</p>
<br class="clear"/>
<center>
<input type="button" class="btn" name="buscar_programs" value="<?php echo $string['LBL_SEARCH_PROGRAMS']; ?>" onclick="javascript:loadPrograms();"/>
</center>
<p>
<label><b><?php echo $string['LBL_PROGRAMS_SELECT']; ?>: <span class="rojo">*</span></b></label>
<span id="area_programs">
<select id="programs" class="multiselect" multiple="multiple" name="programs[]">
</select>
</span>
</p>
Function loadPrograms() (detail.php):
function loadPrograms(){
$.ajax({
url: ruta_fichero_ajax+"loadProgramsItinerario.php?a1="+$('#program_name').val()+"&a2="+$('#center_id').val(),
dataType: 'json',
async: false,
success: function(datos){
var strHTML = '<select id="programs" name="programs[]" class="multiselect" multiple="multiple">';
if (datos.length>0){
$.each(datos, function(index, dato) {
strHTML += '<option value="' + dato.id + '">' + dato.name + '</option>';
});
}
strHTML += '</select>';
document.getElementById("area_programs").innerHTML = strHTML;
$("#programs").multiselect();
}
});
}
I'm a junior and still have many things to learn with Javascript. Thanks for your help.
To append new values to the options list, you can use below code(with jQuery cause you seem to be using jQuery)
$("#programs").append(new Option('TEXT', 'VALUE'));
Or using vanilla JS
selectElement = document.getElementById('programs');
selectElement.options[selectElement.options.length] = new Option('TEXT', 'VALUE');
Alternatively you can check this or w3schools for detailed explanation.
I made a webpage that consists of projects, where each project consists of a list of files. All of this information is acquired from a MySQL database. I've implemented a feature that allows users to comment on each file and reply to each other's comments. I have a php function called "place comments" which recursively places comments for each file shown below.
This is executed for every file and every file is displaced similarly using a while loop and some statements that echo html code.
However, the issue I'm having is using AJAX to post comments without the page refreshing. Since each file id is different, I would have to update every selector with a particular file id and run placeComments again for every file.
However I'm not sure how to accomplish this. I'm able to update my database through AJAX everytime I submit a comment.
I know you can do something like the following and it will update any selector with the id "id":
$(document).ready(function() {
$.get('comments.php', function (data) {
$('#id').html(data);
});
});
But I'm not sure how I can do this iteratively for every file id where each file id is a php variable?
Is there a way I can communicate with JS through PHP so it updates comments
for all file ids? If so, how?
I realized that this is a terrible design, but I'd like to do this without starting my project from scratch.
Place comments function:
function placeComments($mysqli, $parentId, $fileId) {
$sql = "SELECT * FROM Comments WHERE parent = $parentId AND file = $fileId ORDER BY UNIX_TIMESTAMP(date) ASC";
$comments = $mysqli->query($sql);
while($comment = $comments->fetch_assoc())
{
echo '
<ul class="comments">
<li class="clearfix">
<div class="post-comments">
<p class="meta"> '. $comment['date'] .' '. $comment['username'] .' says : <i class="pull-right">
<p>'
.
$comment['content']
.
'</i></p><br><br>';
echo '<div class = "col-sm-12 reply panel-group">';
echo '<div class="panel panel-default">';
echo '<p><a data-toggle="collapse" href="#'. $comment[
'file'] . '-' . $comment['id'] . '"> Reply </a></p>';
echo '<div id="'. $comment['file'] . '-' . $comment['id'] .'" class="panel-collapse collapse">';
echo '<div class="panel-body">';
if(isset($_POST['submitComment-' . $comment['file'] . '-' . $comment['id']]))
{
$user = $_POST['username'];
$content = $_POST['content'];
$fileId = $_POST['id'];
$parent = $_POST['parent'];
$date = date('Y-m-d H:i:s', time());
filterComment($mysqli, $fileId, $user, $parent, $content, $date);
}
echo '<form method="post" class="form-horizontal" id="commentForm" role="form">
<div class="form-group">
<div class="col-sm-10 form">
<h5><b> Name: <b></h5>
</div>
<div class="col-sm-10 form">

Problem
I have problem in sending/passing href value in tablesorter to my dialog modal.
It's become complicated when the target location is the dialog modal.
Example (table.php)
This is a partial of my code since above it is a PDO PHP query to get my data from database. Important point is at the href code inside foreach
if($stmt->rowCount() > 0){
$r=$stmt->fetchAll();
echo "<table class='tablesorter-dropbox' id='myTable' style='width:97%; table-border: 1'>";
echo "<thead>";
echo "<tr style='text-align: center;'>";
echo "<th style='text-align: center;'>No.</th>";
echo "<th style='text-align: center;'>Conference Name</th>";
echo "<th style='text-align: center;'>Conference Sponsor</th>";
echo "<th style='text-align: center;'>Date (Start)</th>";
echo "<th style='text-align: center;'>Date (End)</th>";
echo "<th style='text-align: center;'>Budget</th>";
echo "<th style='text-align: center;'>Status</th>";
echo "<th style='text-align: center;'>Approve</th>";
echo "<th style='text-align: center;'>Reject</th>";
echo "</tr>";
echo "</thead>";
echo "<tbody>";
//echo "<td><a href='reject.php?idstudent=".$row['matricno']."&idbook=".$row['serialno']."'><img src='pic/remove-icon-png-15.png' width=15px></a></td>";
foreach ($r as $row){
echo "<tr align='center'><td>".$row['id']."</td><td>". $row['conf_name'] ."</td><td>". $row['conf_sponsor'] ."</td><td>". $row['conf_fDate'] ."</td><td>". $row['conf_lDate'] ."</td><td>RM ". $row['conf_budget'] ."</td><td>". $row['conf_status'] ."</td><td><a href='#' onclick='this.href='indexSuperUser.php?idconf=".$row['id']."' role='button' data-toggle='modal' data-target='#login-modal3?idconf=".$row['id']."'><img src='images/good.png' width=15px></a></td><td><a href='#?idconf=".$row['id']."' role='button' data-toggle='modal' data-target='#login-modal4'><img src='pic/remove-icon-png-15.png' width=15px></a></td></tr>";
//$startrow++;
}
echo "</tbody>";
echo "</table>";
}
else{
echo "<p align='center'>Nothing to show you :( I am really sorry for this T_T </p>";
}
Example #2 (dialogmodal.php)
Now here is where i want to display the variable from the table. Just for testing purpose i am trying to display the idconf to see if the id displayed successfully.
<!-- BEGIN # MODAL LOGIN -->
<div class="modal fade" id="login-modal3" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" style="display: none;">
<div class="modal-dialog">

<div class="modal-header" align="center">

<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span class="glyphicon glyphicon-remove" aria-hidden="true"></span>
</button>
</div>
<!-- Begin # DIV Form -->

<span id="text-register-msg">Approve this event?.</span>
</div>
<input type="text" id="idconf" class="form-control" value="<?php echo $_GET['idconf']; ?>">
</div>
<div class="modal-footer">
<div>
<button type="submit" class="btn btn-primary btn-lg btn-block" style="background-color: green">Approve</button>
</div>
</div>
</form>
<!-- End # Register Super User Form -->
</div>
<!-- End # DIV Form -->
</div>
</div>
</div>
<!-- END # MODAL LOGIN -->
<!--END LOGIN AREAD--------------------------------->
Result
The result? Its either undefined index: idconf or nothing. Means that im trying to send variable like this #?idconf=".$row['id']."....... since if i put like this dialogmodal.php?idconf=".$row['id'].".. my dialog ends up opening another dialog that is weird to say.
Flow
The flow is simple. Start from the table.php where it will grab the data from my database and display using tablesorter plugins. Then it will open at the dialog modal. Right side of the table have approved and rejected. So this two things comes from the href itself. Just like on the picture.
Duplicated?
Maybe yes. but its a little bit different. I give here two link almost the same problem as me:
Dynamically load information to Twitter Bootstrap modal
Send parameter to Bootstrap modal window?
However. My problem a bit slightly difficult i think. Mine is not about show the data when button clicked. But instead, i need to click the button to open the modal dialog first then clicked href button to open each row with unique id.
my stackoverflow account could be blocked at any time since i got many downvoted question. I dont know what happen to people nowadays. So i try to do proper and detailed here. If still downvoted, it will be my last here.. :)
Oh never mind. I got it work out by using from someone. I can't remember the link but credit to him for mentioning about using "data-your variable" and call it using jquery and send it back to the modal dialog id. Like this
<a id='approved' href='#' role='button' data-toggle='modal' data-target='#login-modal3' data-id='".$row['idconf']."' data-confname='".$row['conf_name']."' data-confsponsor='".$row['conf_sponsor']."' data-conffdate='".$row['conf_fDate']."' data-confldate='".$row['conf_lDate']."' data-confbudget='".$row['conf_budget']."' data-confstatus='".$row['conf_status']."' data-useremail='".$row['email']."' data-username='".$row['name']."' data-balanceuser='".$row['balance']."' data-m='".$row['matricNo_fk']."'><img src='images/good.png' width=15px></a>
See how many data i send? Then call it using jquery like this..
$(document).on("click", "#approved", function () {
var idconf = $(this).data('id');
var confname = $(this).data('confname');
var confsponsor = $(this).data('confsponsor');
var conffdate = $(this).data('conffdate');
var confldate = $(this).data('confldate');
var confbudget = $(this).data('confbudget');
var confstatus = $(this).data('confstatus');
var useremail = $(this).data('useremail');
var username = $(this).data('username');
var balanceuser = $(this).data('balanceuser');
var m = $(this).data('m');
After declare this variable, then on the next line of this code, send it to the modal dialog id such as this.
$(".modal-body #idconf").val( idconf );
$(".modal-body #nameconf").val( confname );
$(".modal-body #sponsorconf").val( confsponsor );
$(".modal-body #dateSconf").val( conffdate );
$(".modal-body #dateEconf").val( confldate );
$(".modal-body #budgetconf").val( confbudget );
$(".modal-body #statusconf").val( confstatus );
$(".modal-body #emailuser").val( useremail );
$(".modal-body #nameuser").val( username );
$(".modal-body #balanceuser").val( balanceuser );
$(".modal-body #m").val( m );
$('#addBookDialog').modal('show');
On the modal dialog, use the id mentioned.
<form id="approved-form">
<div class="modal-body">
<div id="div-register-msg">
<div id="icon-register-msg" class="glyphicon glyphicon-chevron-right"></div>
<span id="text-register-msg">Approve this event?.</span>
</div>
<input type="hidden" id="idconf" class="form-control" value="" disabled>
<input type="text" id="nameconf" class="form-control" value="" disabled>
<input type="text" id="sponsorconf" class="form-control" value="" disabled>
<input type="text" id="dateSconf" class="form-control" value="" disabled>
<input type="text" id="dateEconf" class="form-control" value="" disabled>
<input type="text" id="balanceuser" class="form-control" value="" disabled>
<input type="text" id="budgetconf" class="form-control" value="" disabled>
<input type="text" id="statusconf" class="form-control" value="" disabled>
<input type="text" id="emailuser" class="form-control" value="" disabled>
<input type="text" id="nameuser" class="form-control" value="" disabled>
<input type="hidden" id="m" class="form-control" value="" disabled>
</div>
I am not saying this is efficient in terms of speed or whatever. but it solved my problem and user problem. Case solved
I have a PHP loop created dynamically with two text boxes and one result column.
What i need is , just multiple the values entering first two boxes and show result in its near Result box.
The PHP loop
<?php
$sql=$db->query("SELECT * FROM calc");
foreach($sql as $row)
{
?>
<div class="calc">
<input type="text" id="txt1id<?= $row['id'] ?>" onkeyup="multiple()">
<input type="text" id="txt2id<?= $row['id'] ?>" onkeyup="multiple()">
<input type="text" id="resultid<?= $row['id'] ?>" title="Result shows here automatically">
</div>
<?php } ?> // loop ends here.
And script is
<script>
function multiple()
{
// how to get two different variables like this with different id to multiple ?
var firstBox = parseInt(document.getElementById(firstid).value);
var secondBox = parseInt(document.getElementById(secondid).value);
}
</script>
Pass row id to the function like this
<div class="calc">
<input type="text" id="txt1id<?= $row['id'] ?>" onkeyup="multiple(<?= $row['id'] ?>)">
<input type="text" id="txt2id<?= $row['id'] ?>" onkeyup="multiple(<?= $row['id'] ?>)">
<input type="text" id="resultid<?= $row['id'] ?>" title="Result shows here automatically">
</div>
And change in JS like below
<script>
function multiple(rowid)
{
var firstBox = parseInt(document.getElementById("txt1id"+rowid).value);
var secondBox = parseInt(document.getElementById("txt2id"+rowid).value);
}
</script>
I'm trying to populate multiple form fields from a generated button in a foreach statement. I don't have a vast knowledge of JS so I don't know if I'm just not thinking of a certain function or not.
I have the following code and I'm able to get title to populate in the form but I have no clue where to start for populating content as well based of the same button. ex: one button will load a specific title and content value while another edit button will load another specific title and content value.
//Announcement table select
$sql = "SELECT * FROM `announcements` ORDER BY `startDate` DESC"; //I want to see all existing announcements from database
$announcement = $dbConnect->query($sql);//execute query
$a = 0;
?>
<script type="text/javascript">
function changeText(title, content){
document.getElementById('title').value = title.id;
document.getElementById('content').value = document.getElementById(content).getAttribute('data-content');
}
</script>
<?php
foreach ($announcement as $row){ //Displays title, startDate, endDate from announcement table from database
$x[$a] = $row["title"];
$y[$a] = $row["content"];
echo "<h2 style=width:auto;padding:8px;margin-top:-30px;font-size:18px;><a style=text-decoration:none;color:#c4572f; >".$row["title"]."</a></h2><br>";
echo "<p style=padding-top:10px;>".$row["content"]."</p><br>";
echo "<p style=font-size:10px;>Posted: ".$row["startDate"]."</p><br>";

The following code works
Edit:
<script type="text/javascript">
function changeText(title, content){
document.getElementById('content').value = document.getElementById(content).getAttribute('data-content');
document.getElementById('title').value = document.getElementById(title).getAttribute('data-content');
}
</script>
<?php
foreach ($announcement as $row){ //Displays title, startDate, endDate from announcement table from database
$tile = $row["announcementID"] * 2;
$cont = $row["announcementID"];
echo "<h2 style=width:auto;padding:8px;margin-top:-30px;font-size:18px;><a style=text-decoration:none;color:#c4572f; >".$row["title"]."</a></h2><br>";
echo "<p style=padding-top:10px;>".$row["content"]."</p><br>";
echo "<p style=font-size:10px;>Posted: ".$row["startDate"]."</p><br>";
echo '<input id="'.$tile.'" data-content="'.$row["title"].'" type=button class=test onclick="changeText(id, '.$cont.');" value="Edit">';
echo '<p id="'.$cont.'" data-content="'.$row["content"].'">test</p>';
echo "<h5 style=line-height:2px;margin-top:-15px;><p>_____________________________________</p></h5><br>";
}
?>
You could add a second parameter to your onclick handler:
$a = 0;
?>
<script type="text/javascript">
function changeText(elem, content){
document.getElementById('title').value = elem.id;
/*
* Here we get the value of the hidden content by the passed
* in id and assign it to the value of the #content form element
*/
document.getElementById('content').value = document.getElementById(content).value;
}
</script>
<?php
foreach ($announcement as $row){ //Displays title, startDate, endDate from announcement table from database
$x[$a] = $row["title"];
$y[$a] = $row["content"];
echo "<h2 style=width:auto;padding:8px;margin-top:-30px;font-size:18px;><a style=text-decoration:none;color:#c4572f; >".$row["title"]."</a></h2><br>";
echo "<p style=padding-top:10px;>".$row["content"]."</p><br>";
echo "<p style=font-size:10px;>Posted: ".$row["startDate"]."</p><br>";
echo '<input id="'.$x[$a].'" type=button class=test onclick="changeText(this, '.$y[$a].'); startDate('.$y[$a].'); " value="Edit">';
echo '<p style="display:hidden;" id="'.$y[$a].'" ></p>';
echo "<h5 style=line-height:2px;margin-top:-15px;><p>_____________________________________</p></h5><br>";
}
EDIT:
$a = 0;
?>
<script type="text/javascript">
function changeText(elem, contentID){
var contentElem = document.getElementById(contentID);
document.getElementById('title').value = elem.getAttribute('data-title');
/*
* Get the value of the hidden content's data attribute by the passed
* in id and assign it to the value of the #content form element
*/
document.getElementById('content').value = contentElem.getAttribute('data-content');
}
</script>
<?php
// Let's get $index as well
foreach ($announcement as $index => $row){ //Displays title, startDate, endDate from announcement table from database
$x[$a] = $row["title"];
$y[$a] = $row["content"];
echo "<h2 style=width:auto;padding:8px;margin-top:-30px;font-size:18px;><a style=text-decoration:none;color:#c4572f; >".$row["title"]."</a></h2><br>";
echo "<p style=padding-top:10px;>".$row["content"]."</p><br>";
echo "<p style=font-size:10px;>Posted: ".$row["startDate"]."</p><br>";
// Not sure if I'm escaping quotes correctly on this line:
echo '<input id="title'.$index.'" data-title="'.$x[$a].'" type=button class=test onclick="changeText(this, \"content'.$index.'\"); startDate('.$y[$a].'); " value="Edit">';
// Generate a unique id that we can reference
// and add `data-content` attribute
echo '<p style="display:hidden;" id="content'.$index.'" data-content="'.$y[$a].'"></p>';
echo "<h5 style=line-height:2px;margin-top:-15px;><p>_____________________________________</p></h5><br>";
}
I am not sure what your title and content values are, but I suspect they are not valid HTML element IDs. I think it would be better to avoid using the DOM as a data store and instead create a JSON representation of your announcement table in your script. My PHP is a little rusty, but it should be something similar to:
<script>
var rows = <?php echo json_encode($announcement); ?>;
</script>
Hopefully this will produce something like the following:
var rows = [
{
"title": "Title One",
"content": "Content One"
},
{
"title": "Title Two",
"content": "Content Two"
}
];
This way, our changeText function need only accept a row index as parameter:
function changeText (index) {
document.getElementById('title').value = rows[index].title;
document.getElementById('content').value = rows[index].content;
}
All that is left is to pass the row index where we call changeText:
<?php foreach ($announcement as $index => $row) { ?>
<!-- echo your HTML markup here. -->
<button onclick="changeText(<?php echo $index; ?>);">Edit</button>
<?php } ?>
