PHP SCript Not Accepting AJAX Data - php

Question

This is really bizarre. I am trying to submit data to the server and have a PHP script parse the data and then send back a response. A correctly formed URL is being sent:
http://localhost/ajax/test.html?row=rec_no_1
, but the server does not seem to respond with content from the PHP script despite a return code of 200. In fact, Developer Tools (in Google Chrome) doesn't say anything about the PHP file. The AJAX "data" statement must be formatted properly otherwise I wouldn't get the correct URL. POST (instead of GET) doesn't help.
If I change the AJAX data to a string, then it works fine. This implies there is something wrong with the AJAX data. But I can't understand what given that the URL is correctly formed and does change depending on which row I select.
Any ideas?
Here is the Javascript:
$(document).ready(function() {
$(".submit").click(function() {
$.ajax({
type: 'GET',
url: 'getTable.php',
dataType: 'html',
data: {row: $('input[type='checkbox']:checked').val()},
//data: {row: 'rec_no_2'},
success: function($result) {
$('.tableHolder').text($result);
}
});
return false;
});
});
Here is the PHP code:
<?php
if (isset($_GET['row'])) {
$tableRow = $_GET['row'];
echo $tableRow;
}
else
echo 'TEST';
?>

Answer 1

Your syntax is incorrect:
$('input[type='checkbox']:checked').val()
You should use double quotes around checkbox:
$('input[type="checkbox"]:checked').val()
Anyway do a console.log( $('input[type="checkbox"]:checked').val() ) before the ajax call just to find out which value is being sent.

Try moving your javascript file to server. Ajax don't work on cross domain. You are running the javascript file on localhost and trying to fetch information from live server. Keep both php and javascript file on same server, either live or localhost. It will work fine.
One more thing, try changing the url parameter of your ajax request. try complete url or try putting or not putting a slash / before your filename.
