I have a php page that i call a calendar class function to show the calendar. which is just
$calendar->show(true);
It has another function that lets you call it by
$calendar->show('July 2015')
So what i am trying to do is create a header on top that shows next and previous and then have it be a link, but i am trying to figure out how i can click on the previous link that when i click on it, just reruns the function with the date specified instead of reloading the whole page again and using url parameters. I've been looking into ajax and jquery, it seems possible, but it only shows how to post to a php page. I can't find a way to just rerun a function if thats even possible.
you need code like this:
HTML:
<div id='next' class='year'></div>
<div id='next' class='month'></div>
<div id='prev' class='day'></div>
<div id='date'></div>
<div id='next' class='day'></div>
<div id='next' class='month'></div>
<div id='next' class='year'></div>
jQuery:
$('.day, .month, .year').click(function() {
var a = $(this).attr('id'); // find prev or next clicked
var b = $(this).attr('class'); // find day or month or year clicked
$.ajax({
type: 'post',
url: //your php url,
data: {act: a, which: b, /* your other data */},
cache: false,
success: function(c) {
$('#date').html(c);
}
}):
});
and PHP:
<?php
include //your class
echo $calendar->show('$_POST['data']')
?>

I have divided my content in two tabs and switching between two tabs with javascript.
<div class='tab-container'>
<div class='tab-1'>
<?php
$sql="SELECT * FROM posts WHERE status='tab1'";
echo "<div class='db'
<h2>post</h2></div>";
?>
</div>
<div class='tab-2'>
<?php
$sql="SELECT * FROM posts WHERE status='tab2'";
echo "<div class='db'
<h2>post</h2></div>";
?>
</div>
</div>
Php code divides content between tabs through WHERE clause select * from posts where status='tab1'; so to remove post from one tab ajax request given below triggers php code which updates status of content from tab1 to tab2.
<script type="text/javascript">
$(function() {
$(".restore").click(function(){
var element = $(this);
var del_id = element.attr("id");
var info = 'id=' + del_id;
if(confirm("Restore?"))
{
$.ajax({
type: "GET",
url: "restore.php",
data: info,
success: function(){
}
});
$(this).parents(".db").animate({ backgroundColor: "#fbc7c7" }, "fast")
.animate({ opacity: "hide" }, "slow");
}
return false;
});
});
</script>
So that post is removed from tab1. Idea here is to move post from one tab to another through ajax. javascript works good on removing post from one tab however for making that post appear in another tab I have to reload page as I haven't used ajax for that. So problem is I don't get how to add that post dynamically to another tab through ajax without refreshing page.
To get content from ajax call, you have to echo it in server side.
May be something like this
echo "hi, this is new content";
Now in ajax success
success: function(data){
alert(data); this will alert what was echoed in php(hi, this is new content)
}
If you want to add the content to some div in view,
$("class or id for the div").html(data);
In restore.php, you should get the selected post and then then update the status of that post to tab2. And append that result in main php page. You can append the same via restore.php.
Try this
HTML
<div class="tabs" id="d-tab1"></div>
<div class="tabs" id="d-tab2"></div>
<a href="#" class="restore" id="tab1">
<a href="#" class="restore" id="tab2">
JS
$('.restore').click(function(e){
e.preventDefault();
var $tab = $(this);
$.post('restore.php',{id: $tab.attr('id')},function(html){
$('.tabs').hide();
$('#d-'+$tab.attr('id')).html(html).show();
})
})
Or use Jquery tabs https://jqueryui.com/tabs/
Agree with #Niranjan N Raju. But want to add some addition.
Use console.log(data) instead alert(data) as last don't shows object info.
I'm creating an online exam application in PHP and am having trouble with the AJAX calls.
I want the questions to be fetched (and used to populate a div) using an AJAX call when one of the buttons on the right are clicked. These buttons are not static; they are generated on the server (using PHP).
I'm looking for an AJAX call to be something like this:
functionname=myfunction(some_id){
ajax code
success:
html to question output div
}
and the button should call a function like this:
<button class="abc" onclick="myfunction(<?php echo $question->q_id ?>)">
Please suggest an AJAX call that would make this work
HTML
<button class="abc" questionId="<?php echo $question->q_id ?>">
Script
$('.abc').click(function () {
var qID = $(this).attr('questionId');
$.ajax({
type: "POST",
url: "questions.php", //Your required php page
data: "id=" + qID, //pass your required data here
success: function (response) { //You obtain the response that you echo from your controller
$('#Listbox').html(response); //The response is being printed inside the Listbox div that should have in your html page. Here you will have the content of $questions variable available
},
error: function () {
alert("Failed to get the members");
}
});
})
The type variable tells the browser the type of call you want to make to your PHP document. You can choose GET or POST here just as if you were working with a form.
data is the information that will get passed onto your form.
success is what jQuery will do if the call to the PHP file is successful.
More on ajax here
PHP
$id = gethostbyname($_POST['id']);
//$questions= query to get the data from the database based on id
return $questions;
You are doing it the wrong way. jQuery has in-built operators for stuff like this.
Firstly, when you generate the buttons, I'd suggest you create them like this:
<button id="abc" data-question-id="<?php echo $question->q_id; ?>">
Now create a listener/bind on the button:
jQuery(document).on('click', 'button#abc', function(e){
e.preventDefault();
var q_id = jQuery(this).data('question-id'); // the id
// run the ajax here.
});
I would suggest you have something like this to generate the buttons:
<button class="question" data-qid="<?php echo $question->q_id ?>">
And your event listener would be something like the following:
$( "button.question" ).click(function(e) {
var button = $(e.target);
var questionID = button.data('qid');
var url = "http://somewhere.com";
$.ajax({ method: "GET", url: url, success: function(data) {
$("div#question-container").html(data);
});
});
I know My question Title is not perfectly describe my question extremely sorry about that. I don't know how to tell this as a summery. anyway this is my question.
I am making a admin panel to change some of the content in my web page. this scenario is for change slideshow images.
ok then after someone logged into my page I am loading three pages. like this.
$this->load->view('admin/header');
$this->load->view('admin/menu');
$this->load->view('admin/table_and_editor_holder');
all the page contents I have mentioned below. so basic path is like this. once someone logged he can click the button [slide manage] to load the images and details of already inserted slides. these are getting from a database. so once he clicked the menu button. this jquery function is executing.
$('.menu-item > a').on('click', function() {...})
this function simply getting a html page. filled with previous slide details. this is the controller function handle the menu request.
function slider_edit_delete() {
$sdata['slide_imgs'] = $this->admin_basic_curd->get_all_items('sider_images');
$slide_manager = $this->load->view('admin/slider_manager', $sdata, TRUE);
echo $slide_manager;
}
so previous jquery function is then appending this page content to a div like this.
$('#table_container').html(data);
so inside this page content I have a buttons call edit for each slide already inserted. so by clicking on of this button I can edit that slide image or some test content of it. that button is like this.
<a class="onclick_post_by_a" href="<?php echo base_url() . 'adm_edit_this_slide/' . $sl->id; ?>">
<button class="btn btn-info"> Edit </button>
</a>
so by clicking this button must execute this function in the header section and this function must add a html form (in a separate page) to the #editor-form-container div as previously
$('.onclick_post_by_a').on('click', function() {...})
but the problem is once I click the edit button it couldn't find this function. so it is opening the content as a separate page
How can I make this to work? Thank you
the header page contains all the css and js file links. and some jquery functions. like this.
<script>
$(document).ready(function() {
$('.menu-item > a').on('click', function() {
var url = $(this).attr('href');
var pdata = "";
var rdata = posting_url(url, pdata);
rdata.success(function(data) {
$('#table_container').html(data);
});
return false;
});
$('#editor-form-container').css({
display: "none"
});
function posting_url(url, pdata) {
return $.ajax({
url: url,
data: pdata
});
}
$('.onclick_post_by_a').on('click', function() {
var url = $(this).attr('href');
var pdata = "";
var rdata = posting_url(url, pdata);
rdata.success(function(data) {
$('#editor-form-container').css({
display: "block"
});
$('#editor-form-container').html(data);
});
return false;
});
$('.post_with_image').on('submit', (function(e) {
e.preventDefault();
var formData = new FormData(this);
$.ajax({
type: 'POST',
url: $(this).attr('action'),
data: formData,
cache: false,
contentType: false,
processData: false,
success: function(data) {
console.log("success");
console.log(data);
},
error: function(data) {
console.log("error");
console.log(data);
}
});
}));
});
</script>
</head>
then I have load menu page. it is like this.
<div class="admin-navi">
<div class="menu-item">
Home
</div>
<div class="menu-item">
Side Manage
</div>
</div>
<div class="clearfix"></div>
table_and_editor_holder.php page. it is like this.
<div class="col-lg-12">
<div class="col-lg-2"></div>
<div id="table_container" class="col-lg-8">
</div>
</div>
<div id="editor-form-container" class="col-lg-6">
</div>
Dynamically created element does not respond to direct call to events like below -
$('.onclick_post_by_a').on('click', function() {...})
So you have to write like this
$(document).on('click', '.onclick_post_by_a', function() {...})
Just try it out.
I have a dynamically changing span on a page displaying the number of votes a project has received. On another (target) page i have a list of projects. i want to be able to display that vote count there. i know how to grab the text from the span on the page.
it would be something like this.
<span id="count1"></span>
var prj1c = $("#count1").text;
in know that on the other page i end up using
<?php echo $prj1c(this being after i assign the prj1c var to php somewhere) ?>
i also know i could create a php include page and call it on the target page, though i would like not to create a separate page for each of these instances.
so to sum up: how do i change a JS var to php and call it from another page- remember the text in the span changes (when users vote up or down)?
Try this, use .text() instead of .text
var prj1c = $("#count1").text(); //instead of var prj1c = $("#count1").text;
$.ajax({
type: "POST",
url: "yourpage.php",
data: {count :prj1c},
success: function(response) {
alert("Response "+response);
}
});
in yourpage.php add this <?php echo $_POST['count']; ?>
Update:
$(function(){
$("#count1").click(function(){
window.location='page2.php?count='+$(this).text();
});
});
in page2.php:
<ul>
<li id="projectName">
<img><span>vote count goes HERE: <?php echo $_GET['count']; ?></span>
</li></ul>
You can try with jQuery Ajax request. When user vote up/down you can make an ajax call to the target page.
Eg.
var prj1c = $("#count1").text();
$.ajax({
type: "POST",
url: "targetPage.php",
data: "count="+prj1c,
success: function(response) {
alert("Response "+response);
}
});
Get the prj1c value in targetPage.php
$prj1c = $_REQUEST['count'];
// Follow appropriate steps later in targetPage.php
Thats the best description I could think of. I normally do not post, but I honestly cannot figure this out.
Still in jquery learning mode, and basically what I want to accomplish is that depending on the type of button that is submitted, the script assigns variables to div's on the page. What I am making is a admin side of a user script to allow them to update that particular div that appears on the page.
When I put in the actual selectors, the script works.
When the page loads, it will take the field of the database that corresponds with the and load it. Once they push the update button, a new div will appear. The admin inputs his new data (the new information he wants to display) and it updates the mysql table, then pulls it back in through jquery's ajax.
Sorry for the long explanation. Like I said, I've never really posted, just always liked figuring it out on my own.
php page
<?php //
if(isLoggedIn())
{
echo '<button id="adultClassButton">Edit Class Information</button>';
}
?>
<div class="class" id="adultClass"><?php
$row = checkPost('adult');
echo $row['info'];
?>
</div>
<?php
echo '<div id="adultClassInput">
<textarea rows="2" cols="80" id="adultClassUpdate"></textarea>
<input type="hidden" id="className" name="adult"/>
<button id="adult">Save the Updated Class Info</button></div>';
?>
javascript (jquery) file
$(".button").click(function(){
var button = $(this).attr('id');
if (button == 'adult'){
var classDiv = $("#adultClass");
var className = $("#className");
var classDesc = $("#adultClassUpdate").val();
var classUpdateDiv = $("#adultClassInput");
postData(classDiv, className, classDesc, classUpdateDiv);
}
});
function postData(classDiv, className, classDesc, classUpdateDiv){
$.ajax({
url: 'insert.php',
type: 'POST',
data: "name="+ className+ "& info="+ classDesc,
success:function(data){
$("#" + classDiv).html(data);
}
})
$("#" + classDesc).val('');
$("#" + classUpdateDiv).hide();
}
Like I said, if I have normal selectors in the function, it works as intended. But as of right now, I'm just stumped as to whats wrong.
Thanks a bunch!
classDiv is a jquery object not the ID of the element. So when you use this
$("#" + classDiv).html(data);
That's not working as expected.
Try
classDiv.html(data);
Your function should be like this:
function postData(classDiv, className, classDesc, classUpdateDiv){
$.ajax({
url: 'insert.php',
type: 'POST',
data: {"name": className.val(), "info": classDesc}
success:function(data){
classDiv.html(data);
}
})
$("#"+classDesc).val('');
classUpdateDiv.hide();
}
because you already passed jquery objects (not strings) to your function, except for classDesc.
Hope this helps. Cheers
