Question

I have a form as shown below.

What I have done up to now is assign a checkbox for each item as follows.

<input type="checkbox" name="options[]" value="relevant_value" class="checks">

Now my issue is I can not figure out which the parent item and which is the child item. How can I solve this?

(Given I use Joomla. Get the checkboxes using below code)

$options    = JRequest::getVar('options', NULL, 'post', 'array');

Answer 1

I’ll suggest to use multidimensional array.like this-

For parent-
<input type="checkbox" name="options[]" value="parent" class="checks">
For child-
<input type="checkbox" name="options[parent][]" value="child" class="checks">

get data through-

$options    = JRequest::getVar('options', NULL, 'post', 'array');

see how data comes-

print_r($options);

Now it’s two dimentional,use parent as the key for child to differentiate different parent.

foreach($options as $option){
         $parent[] = $option;
         if(is_array($options[$option]){
             foreach($options[$option] as $opt)
             $childs[$option][]=$opt;
         }

    }

let me know if it’s not clear.
