Is there a way to have a field which only accepts links to youtube videos?

We are having a youtube video contest and we only want people to be able to send us links to their videos hosted on youtube. Is there a way to make sure that any url submitted is a youtube link?

Hi,

You can use conditions as well as the form field validation in order to not only make sure there is a valid URL, but that it also contains the text that you want.  Here is an example form I made that requires a valid URL in a text box as well as "youtube.com", or it will not show the form collapse containing the submit button:

You can clone the form to see the setting by following this guide:

Essentially you would need to block a part of the form conditionally until the text you desire is in a the text box:

There is however no direct way to make sure that a URL is a Youtube URL.

Please let us know if you have any further questions and we will be happy to help.

Thank you for using JotForm!
