Hi,

Is there a way to specify a maximum number of characters in a text field in the CMS? I can't imagine that no one has thought of this! I am looking for the equivalent to the "maxlength" HTML input attribute.

Thanks,
Garrett

Hi Garrett-

The $maxLength variable can be passed when you set up the TextField:

new TextField(
	$name = 'Word',
	$title = 'Short Word',
	$value = $myPage->Word,
	$maxLength = 4;
);

You can also check out the docs for more info:

Hope that helps!

Hi,

Thanks so much for your reply, but it's not working for me. I am still able to type in as many characters as I want, and it publishes successfully. Here's my code:

$fields->addFieldToTab("Root.Content.Main", new TextAreaField('ProjectChallenge', 'The Challenge', '' , 25), 'Content');

What's wrong with this picture??

Thanks again,
Garrett

Hi Garrett-

The code you're showing is asking for a TextAreaField. Try again with a TextField...

$fields->addFieldToTab(
	'Root.Content.Main',
	new TextField(
		'ProjectChallenge',
		'The Challenge',
		'',
		25
	),
	'Content'
);

Let me know how that works out for you!

Thanks,
John

That works, yeah, thanks! Sure wish you could use that for a TextAreaField, though....
