HTML output provided to a PHP file

Question

I have an HTML form, when clicked Submit, gives me an output in JSON format with the help of

$('#result').text(JSON.stringify($('form').serializeObject()));

My HTML form has action="filename.php"* and its method as post

Now I want to send/read these values in a PHP file and should be able to perform operations on them. Like, print them on screen (Echo) or insert them into database.

Please help on how to get the values in readable/accessible format in my php file? Thanks in advance.

Javascript is not needed in this case (at least, with the details currently provided in the question). Also, this is a very basic problem that can easily be solved through a quick Google search. Search for PHP form, PHP POST, PHP GET — STT LCU

$.post('url here', post data here eg: { id : 12 }, function(returnedPage) { this is the callback function eg: alert(returnedPage); }); — Joel Harkes

In filename.php

$formData = json_decode($_POST['fieldname']);

will decode the json string from your form post into a PHP object. If you want an array pass true as the second param to the json_decode method

You'll need to replace fieldname with the attribute name from your HTML / Javascript that holds the json data.

<?php echo json_decode($_GET['Fname']); ?>this is working.. but when I do an echo, I see nothing.

you can't echo an array or object, as such. If you want to see if for debugging then var_dump it. If you want to output it on the page you need to loop over it and echo each node

when I do echo$_GET['Fname'], I see the value entered in my HTML form

Thats because before you do the json_decode() call you have a JSON string, which can be echo'd

hmm makes sense... but when I do var_dump, I see "null" there.

You can post the variables as normal (no JQuery serialization to JSON) and then you can access the posted variables via the $_POST variable in filename.php.
