Drupal form fields FAQ: What is the syntax to make a Drupal form field (textfield, textarea, password field) required?

To make a Drupal form field required, just use the Drupal form #required attribute, as shown in this required textfield example:

$form['first_name'] = array(
  '#title' => t('First Name'),
  '#type' => 'textfield',
  '#required' => TRUE,
);

As you can see, to set a Drupal form field to be required, you just need to add the #required form attribute, and set it to TRUE.

);

That code creates an HTML textfield with the label "First Name", as you can see here:

# this doesn't work
echo $this->Form->text('complexity', array('readonly' => 'readonly'));

When that failed I kept poking on the CakePHP Form input object, and was able to create a readonly text field like this:

I just solved a problem I was having in a Java Swing application getting input focus on a JDialog in a homemade text editor I use on my Mac OS X systems.
