JSON object to php variables

Question

I need to convert a JSON object that the php receive from the html form into php variable. I have two forms form1 gives the values and form2 submits them. this is where I give form2 the JSON string value

-html--javascript function- var myObj = { "username" : theUsername, "name" : theName, "surname" : theSurName, "email" : theEmail, "password" : thePass, "confirmpass" : thePass2, "dob" : theDate, "gender" : theGender, "age" : theAge }; var jsonstr=JSON.stringify(myObj); document.forms["form2"]["hide"].value = jsonstr; //form2 gets the whole string

-php- //$jstr = $_REQUEST["hide"];

//$newObj=JSON.parse(jstr);

//$name = $newObj.name;

This is what I tried, but it doesn't work

I used the post method in the html. How do I now convert it back into seperate variables in php ?

Separate variables? Do you mean: $username, $name, $surname...? — Jose Adrian

It's probably a mere wording issue but JSON can never be an object: JSON is a string. That's why there is an stringify() method. — Álvaro González

Take a look at json_decode

The result of a json_decode is an associative array with the keys and values that were present in your javascript object.

If you don't know how to get the information after you've posted to a PHP script, take a look at the superglobal $_POST. If you're not familiar with that however, I suggest buying a PHP book or read trough some tutorials :)

If you want the string index from de JSON send it to a php page

var myObj = { "username" : theUsername, "name" : theName, "surname" : theSurName, "email" : theEmail, "password" : thePass, "confirmpass" : thePass2, "dob" : theDate, "gender" : theGender, "age" : theAge }

Then in the PHP Page:

 extract($_POST);

Then you should see your variables $name, $surname, $email...
