PHP create dynamic array in a multidimensional array

Question

I want to dynamic create an array based on a number inside a multidimensional array

here is the code

$meta_box = array(  
\'id\' => \'my-meta-box\',
         


        

Answer 1

First you create the array $meta_box as follows:

$meta_box = array(  
  'id' => 'my-meta-box',
  'title' => 'Custom Input Fields',
  'page' => 'page',
  'context' => 'normal',
  'priority' => 'high',
  'fields' => array ()
);

Then you can add the 'dynamic' arrays as follows:

$number = 2;
for ($i = 1; $i <= $number; $i++) {
  $meta_box['fields'][] = array(
    'name' => 'Textarea',
    'desc' => 'Enter big text here',
    'id' => 'textarea_' . $i, //id is textarea + number
    'type' => 'textarea',
    'std' => 'Default value'
  );
}

This starts the numbering for the ids at 1 until $number.
