Foreach loop inside array

Question

I\'m trying to create an array inside an array, using a for loop - here\'s my code:

    array(
    \'label\' => \'Assign to user\',
    \'desc\' => \'C         


        

Answer 1

That's invalid syntax. You'd have to build the "parent" portions of the array first. THEN add in the sub-array stuff with the foreach loop:

$foo = array(
    'label' => 'Assign to user',
    'desc' => 'Choose a user',
    'id' => $prefix.'client',
    'type' => 'radio',
    'options' => array()
);

foreach ($clients as $user) {
    $foo['options'][] = array (  
        'label' => $user->user_login,  
        'value' => $user->user_login,
    );
}

Answer 2

You use foreach to access the data, not define it.

Try this:

array(
    'label' => 'Assign to user',
    'desc' => 'Choose a user',
    'id' => $prefix.'client',
    'type' => 'radio'
    'options' => $clients
    )

If you need to change the structure of the data for 'options', do this before defining the primary array.

Answer 3

You cannot use the foreach in the definition of the array. You can however put the $clients variable in the array itself or you can foreach outside the array to build the array to be inserted at the options key
