Question

In cake php how to avoid one or more elements in option array of select box.

$options = array('One','Two','First','Second');

echo $this->Form->select('trial', $options);

Here I want to avoid ‘First’ and ‘Second’ from array, here option array is coming from DB.

$options = array('One','Two');

Is it possible to do it by any alteration in select method of cake php(i.e array $attributes or anything else ) or manually search the array and drop the values ?

Answer 1

Use array_slice():

echo $this->Form->select('trial', array_slice($options, 0, 2));

Edit:

An alternative solution, if you don’t know the order of the array, and if the values are unique, is by using array_search():

unset($options[array_search('First', $options)]);

Or if the values aren’t unique and you’d like to remove them all, then array_keys() could be useful:

$keys = array_keys($options, 'First');

foreach ($keys as $key)
{
  unset($options[$key]);
}
