PHP Question

Passing Jquery variable to php url

I have a jquery function that looks like this:

$('.dislike_box a').click(function(event){
event.preventDefault();
var title = $(this).data('title');
alert(title);
$.ajax({
url: 'vote.php?vote=dislike&title=title',
success: function(result){
$('.dislike_box p.vote_text').text('Dont Like it.');
}});
});


My issue is when I alert the title variable it is correct but when I pass it to the php script to be put into the database the php script uses the $_GET[] method but puts the literal string "title" into the database instead of the variable value.

Answer: Thanks to @Ivan

url: 'vote.php?vote=dislike&title='+title,

Answer

The variable you are sending via AJAX isn't a variable but the string 'title'. Instead use + to add the variable in the URL.

$('.dislike_box a').click(function(event){
    event.preventDefault();
    var title = $(this).data('title');
    alert(title);
    $.ajax({
    url: 'vote.php?vote=dislike&title='+title, 
    success: function(result){
        $('.dislike_box p.vote_text').text('Dont Like it.');
    }});
});

To retrieve the js variable in PHP file :

<?php

if(isset($_REQUEST['title'])) {
    $title = $_REQUEST['title'];
}
