获取分组的HTML数据到PHP数组？ （像复选框的子元素一样）

Question

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

If a checkbox is checked then this data is to push into a PHP array by saving, needed structure is:

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

As example what I tried is to give by input element name as array like description[] but I cannot control if a checkbox is checked or not...

Hmm. For checkboxes, standard behaviour is the value is only sent if the checkbox is checked. So, a server side solution for this could be:

Firstly, Name the input fields as follows:

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

Or, alternatively

• entries[0][group]
• entries[0][type]
• entries[0][desc]
• entries[1][group]
• entries[1][type]
• entries[1][desc]
• and so on....

The values will be available as an array in $_POST[entries] , if you are using POST method.

$entries = $_POST['entries'];

Now, we need to filter out entries for which it's corresponding checkbox is unchecked. We can use array_filter for that:

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