checking for empty form fields before submission

[nuc63 27]

I use a html form to choose the websites meta tags to fill in info in one bot but sometimes a field is missing, because its incomplete on a submitted site how would check that a form field is empty and then input a variable before submission.

Use and If node then use the Search Page in your evaluation. If found do this if not do that.
