Using $('#form').serialize()
, I was able to send this over to a PHP page. Now how do I unserialize it in PHP? It was serialized in jQuery.
This question is related to

serialization
Provided that your server is receiving a string that looks something like this (which it should if you're using jQuery serialize()
):
"param1=someVal¶m2=someOtherVal"
...something like this is probably all you need:
$params = array();
parse_str($_GET, $params);
$params
should then be an array modeled how you would expect. Note this works also with HTML arrays.
See the following for more information: http://www.php.net/manual/en/function.parse-str.php
This is in reply to user1256561. Thanks for your idea.. however i have not taken care of the url decode stuff mentioned in step3.
so here is the php code that will decode the serialized form data, if anyone else needs it. By the way, use this code at your own discretion.
function xyz($strfromAjaxPOST)
{
$array = "";
$returndata = "";
$strArray = explode("&", $strfromPOST);
$i = 0;
foreach ($strArray as $str)
{
$array = explode("=", $str);
$returndata[$i] = $array[0];
$i = $i + 1;
$returndata[$i] = $array[1];
$i = $i + 1;
}
print_r($returndata);
}
The url post data input will be like: attribute1=value1&attribute2=value2&attribute3=value3 and so on
Output of above code will still be in an array and you can modify it to get it assigned to any variable you want and it depends on how you want to use this data further.
Array
(
[0] => attribute1
[1] => value1
[2] => attribute2
[3] => value2
[4] => attribute3
[5] => value3
)
parse_str($_POST['whatever'], $searcharray);
You can use this function:
function post_unserialize( $key ){
$post_data = array();
$post_data = $_POST[ $key ];
unset($_POST[ $key ]);
parse_str($post_data, $post_data);
$_POST = array_merge($_POST, $post_data);
}
How to use it
$_POST['serialized_data'] = 'var1=1&var2=2&var3=3';
post_unserialize( 'serialized_data' );
Simply do this
$get = explode('&', $_POST['seri']); // explode with and
foreach ($get as $key => $value) {
$need[substr($value, 0 , strpos($value, '='))] = substr(
$value,
strpos( $value, '=' ) + 1
);
}
// access your query param name=ddd&email=aaaaa&username=wwwww&password=wwww&password=eeee
var_dump($need['name']);
In HTML page:
<script>
function insert_tag()
{
$.ajax({
url: "aaa.php",
type: "POST",
data: {
ssd: "yes",
data: $("#form_insert").serialize()
},
dataType: "JSON",
success: function (jsonStr) {
$("#result1").html(jsonStr['back_message']);
}
});
}
</script>
<form id="form_insert">
<input type="text" name="f1" value="a"/>
<input type="text" name="f2" value="b"/>
<input type="text" name="f3" value="c"/>
<input type="text" name="f4" value="d"/>
<div onclick="insert_tag();"><b>OK</b></div>
<div id="result1">...</div>
</form>
on PHP page:
<?php
if(isset($_POST['data']))
{
parse_str($_POST['data'], $searcharray);
$data = array(
"back_message" => $searcharray['f1']
);
echo json_encode($data);
}
?>
on this php code, return f1
field.
Use:
$( '#form' ).serializeArray();
Php get array, dont need unserialize ;)
Why don't use associative array, so you can use it easily
function unserializeForm($str) {
$returndata = array();
$strArray = explode("&", $str);
$i = 0;
foreach ($strArray as $item) {
$array = explode("=", $item);
$returndata[$array[0]] = $array[1];
}
return $returndata;
}

I think you need to separate the form names from its values, one method to do this is to explode (&)
so that you will get attribute=value,attribute2=value
.
My point here is that you will convert the serialized jQuery string into arrays in PHP.
Here is the steps that you should follow to be more specific.
jQuery
to a PHP
page(e.g ajax.php
)
where you use $.ajax
to submit using post or get.(&)
thus separating each
attributes. Now you will get attribute1=value, attribute2=value, now
you will get a php array variable. e.g$data =
array("attribute1=value","attribute2=value")
foreach
on $data
and explode
the (=)
so that you can
separate the attribute from the value, and be sure to urldecode
the value so that it will convert serialized values to the value
that you need, and insert the attribute and its value to a new array
variable, which stores the attribute and the value of the serialized
string.Let me know if you need more clarifications.
// jQuery Post
var arraydata = $('.selector').serialize();
// jquery.post serialized var - TO - PHP Array format
parse_str($_POST[arraydata], $searcharray);
print_r($searcharray); // Only for print array
// You get any same of that
Array (
[A] => 1
[B] => 2
[C] => 3
[D] => 4
[E] => 5
[F] => 6
[G] => 7
[H] => 8
)
Modified Murtaza Hussain answer:
function unserializeForm($str) {
$strArray = explode("&", $str);
foreach($strArray as $item) {
$array = explode("=", $item);
$returndata[] = $array;
}
return $returndata;
}
I don't know which version of Jquery you are using, but this works for me in jquery 1.3:
$.ajax({
type: 'POST',
url: your url,
data: $('#'+form_id).serialize(),
success: function(data) {
$('#debug').html(data);
}
});
Then you can access POST array keys as you would normally do in php.
Just try with a print_r()
.
I think you're wrapping serialized form value in an object's property, which is useless as far as i know.
Hope this helps!
You just need value attribute name in form. Example :
Form
<form id="login_form">
<input type="text" name="username" id="a"/>
<input type="password" name="password" id="b"/>
<button type="button" onclick="login()">Submit</button>
</form>
Javascript
$(document).ready(function(){});
function login(){
var obj = $('#login_form').serialize();
$.post('index.php', obj, function(res){
alert(res);
})
}
PHP - index.php
<?php
if(!empty($POST['username']) && !empty($POST['password'])){
$user = $POST['username'];
$pass = $POST['password'];
$res = "Username : ".$user." || Password : ".$pass;
return $res;
}
?>
