PHP unserialize jQuery FORM post

Question

<form action="index.php" method="POST" id="form">
<input type="text" name="guest" id="guest_name" class="textbox"/><br />
<textarea name="textarea" id="text" class="textarea"></textarea/><br />
<input type="submit" id="submit" class="submit"/><br />
</form>

Jquery

$.post("events.php?action=send", { data :  $("#form").serialize() }, function(data, error) { }

Tested if post DATA has the data in it:

echo var_dump($_POST['data']);

I get this:

name=blabla&comment=blabla1

And then when I do

echo $_POST['guest'];

Nothing comes up, it's a NULL.

Question:

What have I done wrong? Why doesn't the POST guest get filled? if it's in DATA, and form's method is POST too.

Thanks!

It's because you are serializing the form in to the data field in your JQuery that you are getting it like that in PHP. Try getting rid of the data : part in the post function so the data will be past to the $_POST array as expected. — Jon

Pass the serialized string as the data parameter to $.post not an object whose data parameter is the serialized string

$.post("events.php?action=send", $("#form").serialize() , function(data, error) { }

Now you'll be able to access $_POST['guest'] etc

<?php
parse_str($_POST['data'], $data);
print_r($data);

You are doing it in the wrong way. Try like this

$.post(
        "events.php?action=send", 
        $("#form").serialize() , 
        function(data, error) {}
);

On php end access $_POST array like this

echo $_POST['guest'];
echo $_POST['textarea'];

Remove the data key you don't need it.$("#form").serialize() will make a query string in post which you can easily access as you get on usuall form submission.

Object literals must have key/value pairs. Line 3 of your code is not an improvement.

From what you've written it looks like $_POST['data']['guest'] would have what you're looking for in it.
