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">

.
$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">

i have a form in php in which i am trying to add multiple fields on button click, i did the following code:
function add_fields() {
var objTo = document.getElementById('room_fileds')
var divtest = document.createElement("div");
divtest.innerHTML = '
<div class="form-group col-md-6">
<label for="inputPassword4">Item</label>
<?php
$sqlcodes = "SELECT * FROM inventory ORDER BY categoryname ASC";
$resultcodes = mysqli_query($con, $sqlcodes);
echo "<td><select class='form-control' name='item'>";
echo "<option>Select Item</option>";
if ($resultcodes->num_rows > 0) {
while($row = $resultcodes->fetch_assoc()) {
$group[$row['categoryname']][] = $row;
}
foreach ($group as $key => $values){
echo '<optgroup label="'.$key.'">';
foreach ($values as $value)
{
echo '<option value="'.$value['name'].'">'.$value['name'].'</option>';
}
echo '</optgroup>';
}
} else {}
echo "</select></td>";
?>
</div>
<div class="form-group col-md-6">
<label for="inputEmail4">Weight</label>
<input name="weight" type="text" class="form-control" id="inputEmail4" placeholder="Weight">
</div>
';
objTo.appendChild(divtest)
}
<div id="room_fileds">
<div class="form-group col-md-6">

<?php
$sqlcodes = "SELECT * FROM inventory ORDER BY categoryname ASC";

echo "<option>Select Item</option>";
if ($resultcodes->num_rows > 0) {
while($row = $resultcodes->fetch_assoc()) {
$group[$row['categoryname']][] = $row;
}
foreach ($group as $key => $values){
echo '<optgroup label="'.$key.'">';
foreach ($values as $value)
{

</div>
</div>
<input type="button" id="more_fields" onclick="add_fields()" value="Add More" />
however this is not working, i am getting the following error:
** Uncaught ReferenceError: add_fields is not defined
at HTMLInputElement.onclick **
can anyone please tell me what is wrong in here, thanks in advance
As per the comment previously about cloning content and appending that the following goes a step further and uses a content Template to store the content that you wish to add with each button click. This template could hold the generated select menu and would be invisible until added to the DOM. This means you do not have a huge, bloated function that gets called - only some quite simple code to find the template, create a clone and append to the designated parent node.
The below example has the PHP commented out so that the display here looks OK but would need the PHP code re-enabled to produce the actual results you need. None of the code within the template has an ID attribute so there is no need to worry about duplicating IDs.
const clonetemplate=(e)=>{
let parent=document.getElementById('room_fields');
let tmpl=document.querySelector('template#rfc').content.cloneNode( true );
parent.append( tmpl )
}
// Button click handler
document.querySelector('input#add').addEventListener('click',clonetemplate );
// pageload... display initial menu
clonetemplate();
#room_fields > div{margin:1rem;padding:1rem;border:1px solid grey;font-family:monospace;}
#room_fields > div label{display:block;width:80%;padding:0.25rem;margin:0.1rem auto;float:none;}
#room_fields > div select,
#room_fields > div input{float:right}
<div id="room_fields">
<!-- add content here -->
</div>
<input type="button" id='add' value="Add More" />
<!--
Generate the content once that will be repeated
and keep it within a content template until
needed.
-->
<template id='rfc'>
<div>
<div class='form-group col-md-6'>
<label>Item
<select class='form-control' name='item'>
<option>Select Item
<!-- Uncomment this PHP for live version
<?php
$sql = 'select * from `inventory` order by `categoryname` asc';
$res = $con->query( $sql );
$group=array();
while( $rs=$res->fetch_object() ){
$group[ $rs->categoryname ]=$rs;
}
foreach( $group as $key => $values ){
printf('<optgroup label="%s">',$key);
foreach( $values as $obj )printf( '<option>%s',$obj->name );
print('</optgroup>');
}
?>
-->
<option>Hello
<option>World
<option>No IDs
<option>Simples...
</select>
</label>
</div>
<div class='form-group col-md-6'>
<label>Weight
<input name='weight' type='text' class='form-control' placeholder='Weight' />
</label>
</div>
</div>
</template>
In the string that you define in the function add_fields and assign to divtest.innerHTML you have line breaks. You probably also get an error when loading the script saying that you have a syntax error. You should try to avoid line breaks in strings. An alternative solution could be to use backticks for your string. YOu can read about it here: Template literals (Template strings).
Here are two examples. The first fails with both syntax and reference error, the next works fine (but does not do anything).
function add_fields(){
var divtest = document.createElement("div");
divtest.innerHTML = '
test
';
}
<input type="button" id="more_fields1" onclick="add_fields()" value="Add More" />
function add_fields(){
var divtest = document.createElement("div");
divtest.innerHTML = `
test
`;
}
<input type="button" id="more_fields1" onclick="add_fields()" value="Add More" />
So I have this comment system made with PHP and JS (dialogify) and I have two problems: one is obviously the buttons' allignment and the second is the output of the dialog. At the end of each line i get a <br> even though the line ends without going actually on a new line and the row won't update after pressing ok, I have to reload the page to actually see the updated content.
EDIT: Now the buttons are alligned
<div class="row">
<div class="col-sm-12 text-right">
<form method="post" action="">
<button class="btn btn-warning btn-sm" id="<?php echo $row['id']; ?>" value="Edit" type="button" onclick="edit_row('<?php echo $row['id']; ?>');" /><i class='fa fa-pencil'></i></button>
<button class="btn btn-danger btn-sm" name="delete_reply" type="submit"><i class='fa fa-trash'></i></button>
</form>
</div>
</div>
Here is the code I use to display the comments.
$query_reply = $mysqli->prepare("SELECT * FROM replies WHERE postID=?");
$query_reply = $mysqli->bind_param("i",$postid);
$query_reply ->execute();
$row = $query_reply->fetch_assoc();
<div id="content_val<?php echo $row['id']; ?>"><?php echo nl2br($row['reply']);?><br /></div>
The code for the insertion
if (isset($_POST['edit_row'])) {
$sql = $mysqli->prepare("UPDATE replies SET reply=? WHERE id=? AND postID=?");
$id = $_POST['id'];
$content = $_POST['content'];
$postid = $_SESSION['id'];
$sql->bind_param("sii", $content, $id, $postid);
if ($sql->execute()) {
$sql = $mysqli->prepare("SELECT * FROM replies WHERE postID='$id'");
$sql->bind_param("i", $postid);
$sql->execute();
}
}
EDIT 2: I managed to make the content update in real time by changing the action after $sql->execute();
if ($sql->execute()) {
print "success";
} else {
$error_message = "Problem in editing Record";
}
I got the search box in the navigation bar at the top.
<li class="nav-item">
<form action="model/action-search.php" class="search-form" method="POST">
<div class="form-group has-feedback">
<label for="search" class="sr-only fa fa-search">Search</label>
<input type="text" class="form-control" name="search" placeholder="search">
<input type="submit" name="submit">
</div>
</form>
</li>
The action file.
if(isset($_POST['submit']))
{
$search = stripcslashes($_POST['search']);
$search = mysqli_real_escape_string($con,$search);
$query = $con->query("SELECT * FROM agencyemployee MATCH (agcName , nmName , agcemail) AGAINST ('".$search."')");
header("Location:../sampsearch.php");
}
I already have a row of nursemaid displayed here. What I want is that when I search something I want to replace the displayed row with the searched text here.
<div class="row">
<?php
$query = $con->query("SELECT * FROM agencyemployee");
while($row = mysqli_fetch_array($query))
{
?>
<div class="col-md-4 col-sm-6 portfolio-item">
<div class="portfolio-caption">
<h4><?php echo $row['nmName']; ?></h4>
</div>
</div>
<?php}?>
Firstly I would suggest using GET for you form method as that way your search string would be reflected in the URL and you can refer to it.
If I understand well and what you want to do is highlight the searched text in each row then I would do something like this:
<div class="row">
<?php
$query = $con->query("SELECT * FROM agencyemployee");
while($row = mysqli_fetch_array($query)) : ?>
<div class="col-md-4 col-sm-6 portfolio-item">
<div class="portfolio-caption">
<h4>
<?php
$name = $row['nmName'];
if (isset($_GET['search'])) {
$name = str_replace($_GET['search'], "<span class='search-highligh'>" . $_GET['search'] . "</span>", $name);
}
?>
<?php echo $name; ?>
</h4>
</div>
</div>
<?php endwhile;?>
If i am able to understand your problem then you should follow below instruction:
You should just update the $query variable as your requirement like you want to fetch searched information or all information. In that case just slightly change your code:
<div class="row">
<?php
$query = "SELECT * FROM agencyemployee";
if(isset($_POST['submit']))
{
$search = stripcslashes($_POST['search']);
$search = mysqli_real_escape_string($con,$search);
$query = "SELECT * FROM agencyemployee MATCH (agcName , nmName ,
agcemail) AGAINST ('".$search."')";
}
$result = $con->query($query);
while($row = mysqli_fetch_array($result))
{
?>
<div class="col-md-4 col-sm-6 portfolio-item">
<div class="portfolio-caption">
<h4><?php echo $row['nmName']; ?></h4>
</div>
</div>
<?php } ?>
Problem
I have problem in sending/passing href value in tablesorter to my dialog modal.
It's become complicated when the target location is the dialog modal.
Example (table.php)
This is a partial of my code since above it is a PDO PHP query to get my data from database. Important point is at the href code inside foreach
if($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>
<input type="text" id="idconf" class="form-control" value="<?php echo $_GET['idconf']; ?>">
</div>
<div class="modal-footer">

</div>
</div>
</form>
<!-- End # Register Super User Form -->

<!-- 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 want to save data from input fields to mysql database so first I create a modal window and input fields:
<!-- Button trigger modal -->
<button class="btn btn-success" data-toggle="modal" data-target="#myModal">
Add new</button>
<div id="output"></div>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title" id="myModalLabel">Add new row</h4>
</div>
<div class="modal-body">
......
<div class="input-group">
<span class="input-group-addon">Ime</span>
<input type="text" id="Ime" class="form-control" placeholder="Upisi ime">
</div>
</br>
<div class="input-group">
<span class="input-group-addon">Pol</span>
<input type="text" id="pol" class="form-control" placeholder="Pol (male/female)">
</div>
</br>
<div class="input-group">
<span class="input-group-addon">Godine</span>
<input type="text" id="godine" class="form-control" placeholder="Godine starosti">
</div>
</br>
<div class="input-group">
<span class="input-group-addon">Broj pojedenih krofni</span>
<input type="text" id="krofne" class="form-control" placeholder="Pojedene krofne">
</div>
</br>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button id="newData" class="btn btn-primary">Add new data</button>
</div>
</div>
<!-- /.modal-content -->
</div>
<!-- /.modal-dialog -->
</div>
<!-- /.modal -->
Now I write jQuery AJAX code to add data to database:
<script>
//add data to database using jquery ajax
$("#newData").click(function() {
//in here we can do the ajax after validating the field isn't empty.
if($("#ime").val()!="") {
$.ajax({
url: "add.php",
type: "POST",
async: true,
data: { Name:$("#ime").val(), Gender:$("#pol").val(), Age:$("#godine").val(), Donuts_eaten:$("#krofne").val()}, //your form data to post goes here as a json object
dataType: "html",
success: function(data) {
$('#output').html(data);
drawVisualization();
},
});
} else {
//notify the user they need to enter data
}
});
</script>
and finally I create a php file (add.php)
<?php
$con = mysql_connect('localhost', 'gmaestro_agro', 'pass') or die('Error connecting to server');
mysql_select_db('gmaestro_agro', $con);
mysql_select_db('gmaestro_agro', $con);
$query = "INSERT INTO `stat` (`Name`, `Gender`, `Age`, `Donuts eaten`) VALUES (";
$query .= mysql_real_escape_string($_POST['Name']) . ", ";
$query .= mysql_real_escape_string($_POST['Gender']) . ", ";
$query .= mysql_real_escape_string($_POST['Age']) . ", ";
$query .= mysql_real_escape_string($_POST['Donuts_eaten']);
$query .= ")";
$result = mysql_query($query);
if($result != false) {
echo "success!";
} else {
echo "an error occured saving your data!";
}
?>
Now, when I try to add data I just get this error: an error occurred saving your data!.
What is the problem here exactly? I try to find the error whole day...
You are not quoting your strings:
$query .= mysql_real_escape_string($_POST['Name']) . ", ";
should be:
$query .= "'" . mysql_real_escape_string($_POST['Name']) . "', ";
(for all string values)
By the way, it would probably make your life easier if you switched to PDO or mysqli and prepared statements. Then you would not have to escape and quote your variables and the mysql_* functions are deprecated anyway.
$query = "INSERT INTO `stat` (`Name`, `Gender`, `Age`, `Donuts eaten`) VALUES (";
$query .= "'".mysql_real_escape_string($_POST['Name']) . "', ";
$query .= "'".mysql_real_escape_string($_POST['Gender']) . "', ";
$query .= "'".mysql_real_escape_string($_POST['Age']) . "', ";
$query .= "'".mysql_real_escape_string($_POST['Donuts_eaten']);
$query .= "')";
Put all the values in single quotes.
