Hi There,

I created a document type and having a text field to capture website URL as it's not mandatory field so I have checked "Allow empty value" to true but I'd like ensure if any user entering the value in this filed, that must a valid URL. To achieve it I used the "Regular expression" option.

Now problem is that, entered Regular expression still firing even user not entering any value. what I want my Regular expression should fire if there is any value user entering otherwise not.

Any help would be appreciate!

kind Regards Dilip

Technically an empty string is not a valid URL. So your regular expression will have to accommodate for that.

You could also use a URL selector as a control type vs. a textbox. Using this you can configure this to allow or not allow someone to choose attachments, content tree items, media library items and/or a website URL. It makes it easier for someone to enter or select a link.

Hi Brenden,

Thanks for your reply!

I tried to use URL selector apart from text box but it's not validate the input means a valid URL formate.

Could you please let me know if there is any additional setting I need to do.

Thanks

Hi Dilip,

you can try regular expression such as ^($|https?://.*$). Update the inner condition as you need to match desired format.

You are correct Dilip, it does not validate the URL ALTHOUGH it does give the user something to select from VS manually typing in which will give you better results than you'd expect. The user will find out pretty quick if their link is broken.
