Data Is Getting Lost During $.post

I have a list

of articles
• and an event handler on a button. When clicking the button, I aggregate all
• s ID (integer) using: data.articles = $('#cat

Solution 1:

Duplicate of Array being chopped off over ajax post. Ajax posting limit? ?

Suggests that it's to do with PHP's max_input_vars: This limit applies only to each nesting level of a multi-dimensional input array.

To solve this without editing the server configuration:

// Serialize the elements into a single var using join():

data.articles  = $('#category-articles').sortable('toArray').join(';');

And on the serverside:

// Unserializing the single variable back into an array:$articles = explode(';', $_POST['articles']);

The delimiting char ;must not appear inside the elements, chose a different character if it is a problem.
