I’m developed an extension to add validation to the text field type.  Once this extension is enabled you’ll see a drop down when your editing (or creating) a text field.  Choose from the list to validate entries against a specified regular expression.  Or if you’re feeling adventurous, switch the field type to a Drop-down List and enter a regex in the textarea like so:

Just note that all the regex’s have to start with a ‘v:’ followed by the expression.  Fell free to add as many php-valid modifiers as you’d like.  The above would ensure that the field is composed of all alphanumeric characters.

Great extension Mark!

Would it be possible to honor the “Is this a required field?” setting?
Right now it’s not possible to leave a field empty.

Cheers

I’m not sure what you mean by “required”?

Got it cocoaholic, ext has been updated to 1.0.1 to allow empty entries.

Mark Huot you are an extension making machine! Thanks for sharing them :D

Thanks Mark!

What do the “settings” do for this extension?

Did they accidentally sneak into your code, or are you working on more cool features?

You got it cocoaholic, it snuck in there from my Multi-text extension.  I’ve since removed it and added new settings so that if you define your own regular expression match you can then define your own error message in the settings page.  Enjoy, version is 1.0.2 at the top of the thread.

version 1.0.3 fixes the alerts to use the field labels not the names.

Mark, any chance of getting this to work with standalone entry/edit forms?

Another request to have this work with SEAFs.  It looks like the validation works, but instead of getting the user message template with the error message when and invalid field is submitted, I get a blank screen.  I would love to be able to use this extension on a current project.

Having looked at the documentation and this thread, I’m still confused as to how I would add this regular expression to the dropdown menu to check for a price field:

[0-9]+\.[0-9][0-9]

How would I add ‘Price’ to the validation drop down, using this regex?

TY!

Wonderful Job! Thanks for sharing them Mark.
