Issue in uploading file

Question

I am trying to upload files 62 Mb. It giving me following error :

Failed to load resource

I am using following jquery for multiple upload :

var form_data = new FormData();                 
     jQuery.each($('#images')[0].files, function(i, file) {
     form_data.append('file[]', file);
       });
     form_data.append("postId", postId) 
        $.ajax({    
            url: '<?php echo get_bloginfo('template_directory') ?>/upload_files.php',
            type: 'POST',
            dataType: 'script/html',
            contentType: 'multipart/form-data',
            cache: false,
            contentType: false,
            processData: false,
            data: form_data, 
            success: function(response) {
                $("#show_progress").hide();
                alert(response);
            },
            error: function() {
                $("#show_progress").hide();
                $("#end_progress").show();
                $("#images").val('');
                }
        });
         }
        });     
});

And php file :

foreach($_FILES['file']['tmp_name'] as $key =>$tmp_name ) 
{

    $name = $_FILES['file']['name'][$key];
    $tmp_name =  $_FILES['file']['tmp_name'][$key];                 
    $target_path = $gal_path."/". $_FILES["file"]["name"][$key];
    move_uploaded_file($_FILES["file"]['tmp_name'][$key],$target_path);
    mysql_query("INSERT INTO wp_group_upload SET upload_group_id = '$gid', upload_img_name = '$name'");

}
?>

Can you tell me what's wrong?

I think your problem is here :
See the single quotes!

url: '<?php echo get_bloginfo('template_directory') ?>/upload_files.php'

If template_directory is a javascript variable, it must be written like this :

url: '<?php echo get_bloginfo('+template_directory+') ?>/upload_files.php'

If template_directory is a string given to get_bloginfo() function, it must be written like this :

url: '<?php echo get_bloginfo("template_directory") ?>/upload_files.php'

or :

url: "<?php echo get_bloginfo('template_directory') ?>/upload_files.php"
