Get grouped HTML data into a PHP array? (Similar to sub-elements of a check box)

Question

How to convert this form structure to a PHP array? I can also edit HTML, so every idea is good ...

If the checkbox is selected, then this data should be inserted into the PHP array by saving, the necessary structure:

0 =>
   'group' => 'group_a',
   'type' => 'type_yellow',
   'desc' => 'now to convert'
1 =>
   'group' => 'group_b',
   'type' => 'type_orange',
   'desc' => 'needed to order'

As an example, I tried to specify inputthe element name as arrayhow description[], but I can not control whether the checkbox is checked or not ...

Hm. For flags, standard behavior is a value that is sent only if the flag is checked. Thus, a solution for the server side for this could be:

-, :

• entries[][group]
• entries[][type]
• entries[][desc]

,

• entries[0][group]
• entries[0][type]
• entries[0][desc]
• entries[1][group]
• entries[1][type]
• entries[1][desc]
• .....

$_POST[entries], POST.

$entries = $_POST['entries'];

entries, . array_filter :

$entries = array_filter($entries, function($entry) {
    return isset($entry['group']);
});
