  • Stackoverflow expects you to perform a degree of research before you ask a question (and to share the results of that research in the question). There is nothing here which suggests you've investigated form validation at all.

You can use the required attribute. When present, it specifies that an input field must be filled out before submitting the form. In your code, you could have something like this:



<input type="text" name="t1" size=18 required>


the required attribute works with the following input types: text, search, url, tel, email, password, date pickers, number, checkbox, radio, and file. You can read more about it here or here.



Cheers!
