It's not possible...PHP runs on the server and JavaScript runs on the client (browser). PHP and JavaScript are executed at different times, so one cannot call the other.

What do you mean by

if my contents of form is set with mysql database

? I don't get that condition.

But anyway, you can have the form submit to a PHP script, the PHP script will check, and if it satisfies the condition, do something. If it doesn't satisfy the condition, re-output the form.

i think you can use php in between java script and in that you can call function which will set required variable(hidden field) value in that function and use that variable in java script
