I am trying to pass variable when user click on link to page single.php
Here is my code
<a href='#' id='8' class='clickme' style='font-weight:bold;color:white;font-size:16px;'>";
In function.php, I put this code:
/////////////////////////////////////////////////////////
add_action( 'wp_head', 'myajaxcall' );
function myajaxcall(){ ?>
<script type="text/javascript">
jQuery(document).ready(function($) {
jQuery(".clickme").click( function() {
// We'll pass this variable to the PHP function example_ajax_request
var id = $('.clickme').attr('id');
// This does the ajax request
$.ajax({
url: <?php echo admin_url( 'admin-ajax.php'); ?>,
data: {
'action':'get_sidebar_request',
'page_id' : id
},
// beforeSend: function (jqXHR, settings)
// {
// alert( url = settings.url);
//},
success:function(data){
alert(data);
},
error: function(errorThrown){
//alert(errorThrown);
}
});
});
});
</script>
<?php }
add_action( 'wp_ajax_get_sidebar_request', 'idAjax' );
add_action( 'wp_ajax_nopriv_get_sidebar_request', 'idAjax' );
function idAjax()
{
require( get_template_directory() . '/single.php' );
}
/////////////////////////////////////////////////////////////////////
And in file `single.php, when I want to get the passed variable, I put this code:
$page_id=0;
$page_id = $_REQUEST['page_id'];
echo "page_id=".$page_id;
But the variable isn’t passing to single.php. I try to echo it, and nothing happens.
Can you help me?
You can use Network tool in Google Chrome to debug and see sent/received data.
If “id” is not null when you send it, try to use $_POST to output your data in your php file, like this :
check this :
and add double quote to url value
if you don’t see your ajax call, it’s a javascript error in your code.
Do you have any error in browser Console ?
