Okay, so I defined a CSS class and put it into a file in the parts/css folder:

.mcw-editor-short {
	height: 140px;
}

And then I added editor_class to an editor field:

		array(
			'type' => 'editor',
			'field' => 'newsletter_highlights',
			'label' => __( 'Highlights of this issue' ),
			'columns' => 12,
			'options' => array (
				'media_buttons' => false,
				'editor_class' => 'mcw-editor-short',
				'teeny' => true,
			),
		),

But the class is applied to a textarea that is display: none, so it doesn’t affect the height of the editor box. See attached Firebug screenshot.

Again, could be pilot error … so set me straight if I’m goofing up! 🙂

Also, is there a better way to limit the height of an editor field? I tried

	'attributes' => array (
		'rows' => 3,
	),

But that doesn’t work.

Thanks!

Since it won’t allow me to upload the .php file, here’s the field definition:

piklist('field', array(
	'type' => 'group',
	'field' => 'newsletter_archive',
	'label' => 'Newsletter Archives',
	'description' => 'Each archive includes an image, title and section for highlighting the content of the newsletter.',
	'columns' => 12,
	'add_more' => true,
	'template' => 'field',
	'fields' => array(
		array(
			'type' => 'text',
			'field' => 'newsletter_archive_title',
			'label' => 'Issue Date',
		),
		array(
			'type' => 'file',
			'field' => 'newsletter_file',
			'label' => 'Upload or choose a PDF',
			'options' => array(
				'modal_title' => 'Add File(s)',
				'button' => 'Add',
			),
		),
		array(
			'type' => 'editor',
			'field' => 'newsletter_highlights',
			'label' => __( 'Highlights of this issue' ),
			'options' => array (
				'wpautop' => true,
				'media_buttons' => false,
				'tabindex' => '',
				'editor_css' => '',
				'editor_class' => '',
				'teeny' => false,
				'dfw' => false,
				'tinymce' => true,
				'quicktags' => true,
			),
		),
		array(
			'type' => 'file',
			'field' => 'newsletter_image',
			'label' => 'Add a cover image',
			'options' => array(
				'modal_title' => 'Add File(s)',
				'button' => 'Add',
			),
		),
	),
));

One tip for anyone who has defined piklist fields inside their theme.

In order to deactivate Piklist, I renamed my theme’s piklist file to piklistx. Then I switched to the new Piklist plugin files, reactivated it, and ran the update. Oops, it didn’t find my theme’s piklist parts so it didn’t run the update on them.

So if you use this method to deactivate Piklist before the upgrade, make sure you switch the name back before running the database update.

Then I found this page: https://piklist.com/user-guide/docs/piklist_sanitization_rules/
So I added a ‘piklist_sanitization_rules’ filter and created a rule for ‘mcw_integer’, using the same callback function:

add_filter( 'piklist_sanitization_rules', 'mcw_add_sanitize_rule', 11 );
function mcw_add_sanitize_rule ( $sanitization_rules ) {
	$sanitization_rules['mcw_integer'] = array(
		'callback' => 'mcw_sanitize_integer'
	);
	return $sanitization_rules;
}
 
function mcw_sanitize_integer ( $value, $field, $options ) {   
	$number = preg_match( '/^[0-9]+$/', $value );
	$number = (int)$number;
	if ( isset( $options['non_negative'] ) && $options['non_negative'] && ( $number < 0 ) ) {
		return '0';
	} else {
		return "$number";
	}
}

I changed the field definition to:

piklist('field', array(
	'type' => 'text',
	'field' => 'donation',
	'scope' => 'post_meta',
	'value' => '',
	'template' => 'mcw_quantity',
	'label' => 'Amount of Donation',
	'sanitize' => array(
		array(
			'type' => 'mcw_integer',
			'options' => array(
				'non_negative' => true,
			),
		),
    ),
    'required' => false,
));

The good news is that it does call the callback function. But it kept giving me an error message: ‘PHP Notice: Undefined index: type in /…/wp-content/plugins/piklist/includes/class-piklist-validate.php on line 304

But of course, now that I’m reporting this, the error message has gone away. So it looks as though the second model is working.

It would be really helpful to have one complete example that shows both ends of the process, and I would like to know what I did wrong with my first attempt.

Thanks! 🙂
