I want to send the SQL condition statement using the id of the link element which is the category of the product to be generated by php file and loaded back to the div with class load_area. I get the category with .attr() method and then send this data as the string {'category='"+cat+"'} to the php file. The string sent should be


but this is what I got as a print result in php file


As you can see that the php file automatically added the escape character to the string I sent to it and the query couldn't be successfully processed. I am so frustrated trying to find the right way solving the problem. So please help ...

This is my HTML

<a id="bag" href="#">Bag</a>
<div class="load_area"></div>

This is javaScript

$(document).ready(function() {
    $('a').click(function() {
        var cat = $(this).attr('id');
        $('.load_area').load('controllers/genproduct.php', {'condition':'category='"+cat+"'});

This is my php script

$condition = explode("=", $_POST['condition']); // Get condition
$limit = $_POST['limit']; // Get limit
$store = new store_manager(mysql_connect("localhost", "root", "1234"), "gemalong",     "cart", "products");
if(isset($condition) || $condition != "") {
if(isset($limit) || $limit != "") {
    $getquery = $store->product_gen($condition, $limit);
else {
    $getquery = $store->product_gen($condition);
else {
$getquery = $store->product_gen();
while($data=mysql_fetch_array($getquery)) {
$pid = $data['id'];
$pname = $data['name'];
$pdesc = $data['description'];
$pprice = $data['price'];
$ppix = $data['pix'];
// Start generating view
echo "<div class='each_product'>";
    echo "<div class='img_container'>";
        echo "<a id='ppixlink".$pid."' href='#' alt='".$pname."'><img      src='".$ppix."' title='".$pname."' /></a>";
    echo "</div>";
    echo "<p class='product_name'><a id='plink".$pid."' href='#'     alt='".$pname."'>".$pname."</a></p>";
    echo "<div class='down_pb clearfix'>";
        echo "<p>$ ".$pprice."</p>";
        echo "<button type='button' id='productaddbtn".$pid."' class='addcart-btn'>Add to cart</button>";
    echo "</div>";
echo "</div>";
// Close connection

    Dont send a string that needs manipulating in php, send two fields instead:

    $('.load_area').load('controllers/genproduct.php', {field: 'category', value: cat});
    $condition = array($_POST['field'], $_POST['value']);
