Retrieving serialize data in a PHP file called using AJAX - php

Question

Form sending AJAX code:
var str = $("form").serialize();
alert(str);
// var uns=#unserialize(str);
//alert(uns);
$.ajax({
type: "POST",
url: "update.php",
data: "box1="+str,
success: function(value)
{
$("#data").html(value);
}
HTML Form:
<form>
<input type=checkbox name=box[] value='1'/><input type=checkbox name=box[] value='2'/>
</form>
In my PHP:
$box=$_POST['box1'];
How can I access each of the box variable values in PHP side?

Answer 1

Your js should be like this:
var str = $("form").serializeArray();
$.ajax({
type: "POST",
url: "update.php",
data: str,
success: function(value) {
$("#data").html(value);
}
});
With php you should loop your result array.
$box = $_POST['box'];
foreach ($box as $x) {
echo $x;
}
Edit:
You have to use serializeArray function in jQuery. Then it will work with this code.

Answer 2

Provided that your server is receiving a string that looks something like this
$("form").serialize();
"param1=someVal&param2=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
Hope that's helpful. Good luck!

Answer 3

your JS should be like this -
var str = $( "form" ).serializeArray();
var postData = new FormData();
$.each(str, function(i, val) {
postData.append(val.name, val.value);
});
$.ajax({
type: "POST",
data: postData,
url: action,
cache: false,
contentType: false,
processData: false,
success: function(data){
alert(data);
}
});
Now do this in your php script -
print_r($_POST);
you will get all form data in alert box.

Answer 4

$data = array();
foreach(explode('&', $_POST[data]) as $value)
{
$value1 = explode('=', $value);
$data[$value1[0]] = validateInput($value1[1]);
}
var_dump($data['box']);

Answer 5

your data in php will contain a string like this
field1=value1&field2=value2&....
so you can get your value1 using $_POST['field1] , value2 with $_POST['field2']

Answer 6

Change
data: "box1="+str,
into
data: str,
serialize() will produce a string like: input1=value1&input2=value2. So in your php you can access each value with, for instance $value1 = $_PHP['input1'];

Answer 7

values=$("#edituser_form").serialize();//alert(values);
$.ajax({
url: 'ajax/ajax_call.php',
type: 'POST',
dataType:"json",
data: values,
success: function(){
alert("success");
},
error: function(){
alert("failure");
}
});

Answer 8

$box=$_POST['box'];
and $box is an array.
