Im trying to pass a mulitidimensional Javascript array to another page on my site by:

• using JSON.stringify on the array




• assigning the resultant value to an input field




• posting that field to the second page




• using json_decode on the posted value




• then var_dump to test




• (echo'ing the posted variable directly just to see if it came through
  at all)

Javascript on page one:

var JSONstr = JSON.stringify(fullInfoArray);

document.getElementById('JSONfullInfoArray').value= JSONstr;

php on page two:

$data = json_decode($_POST[JSONfullInfoArray]);

var_dump($data);



echo($_POST[JSONfullInfoArray]);

The echo works fine but the var_dump returns NULL

What have I done wrong?

This got me fixed up:

$postedData = $_POST[JSONfullInfoArray];

$tempData = str_replace(\, ,$postedData);

$cleanData = json_decode($tempData);

var_dump($cleanData);

Im not sure why but the post was coming through with a bunch of characters separating each variable in the string

Figured it out using json_last_error() as sugested by Bart which returned JSON_ERROR_SYNTAX
