在以下情况下如何访问PHP文件中的序列化数据？

Question

How to access the serialized data in a PHP file in following situation? The code and the serialized data is as follows:

$(document).ready(function() { $(document).on('click', '#delete_url', function (e) {    
e.preventDefault();

var items = new Array();
$("input:checked:not(#ckbCheckAll)").each(function() {
  items.push($(this).val());
});

var str = $("#user_filter").serialize();    


$.ajax({
  type: "POST",
  url: "manage_users.php?op=delete_bulk_users&items="+items,
  data: str,
  dataType: 'json',  
  success: function(data) {
    //var message       = data.success_message;            
    var redirect_link = data.href;
    alert(redirect_link);
      window.location.href = redirect_link;
  }          
});

}); });

The data I'm getting in after serialize in str is as follows:

op=group_filter&page=1&from_date=11%2F10%2F2000&social_login=&to_date=11%2F10%2F2013&login_criteria=all&user_name=&user_state=&user_email_id=&user_city=

Now the PHP file(manage_users.php) is as follows:

/*The code is actually one of the switch casees*/
prepare_request();
  $request = empty( $_GET ) ? $_POST : $_GET ;
$op         = $request['op'];
switch( $op ) {
case "delete_bulk_users":
print_r($request);/*For printing the received array of values after form submission
                    Here I'm not getting serialized data */
}

Thanks in advance.

The serialize function is intended to be used to create a query string for a URL from a collection of inputs (or an entire form), and will out of necessity encode characters such as / (which denotes a directory in a URL). There's no way to tell .serialize() to convert to the "proper" format because it already is .

If you're using the result of .serialize() as part of an AJAX request it's fine to do that like so:

$.ajax({
    url: 'yourpage.php',
    data: str, // the string returned by calling .serialize()
    ... // other options go here
}).done(function(response) {
    // do something with the response
});

Your server should handle decoding those characters when it receives the request and provide the correct values to you.

If you're using it for something else you could try using the native JavaScript decodeURIComponent function to convert those encoded characters back, like so:

str = decodeURIComponent(str);

Note that calling decodeURIComponent and then trying to use it for an AJAX request won't work.

For more information on URI encoding take a read through the MDN entry for encodeURIComponent .
