Validation rule with regex

Yes, you can do that with custom HTML5 attribute pattern. Please follow the instructions here:

https://metabox.io/docs/custom-attributes-for-inputs/

Thank you,
but please help me again, i tried this

array(
			'name' => 'subtitle',
			'id' => $prefix . 'subt',
			'type' => 'text',
			'required'  => true,
			'regex'   => '[1-9][a-d]',
			),

what’s wrong?

There is no regex attribute. You should use pattern attribute. The format can be found at:

okey, so I tried

array(
			'name' => 'subtitle',
			'id' => $prefix . 'subt',
			'type' => 'text',
			'pattern'   => '[1-9][a-d]',
			),

the HTML-Source looks fine for me

<div class="rwmb-input">
<input id="px_subt" class="rwmb-text" type="text" name="px_subt" pattern="[1-9][a-d]" size="30">
</div>

but i don’t get any error-message for wrong inputs.

Just tested and found that the validation module doesn’t work well with pattern attribute. I’ve just pushed a fix on Github, please download the development version on Github and try again.
