I know the tag form has an attribute called action and I know how action works, this is how I used it
<form method="post" action = "registerd.php">
</form>
The registerd.php page also exists as well. Now I am doing some validation in the tag form using php validation, but why does it jump to the registerd.php page without validating the values at first? is there any other solutions to this rather than using the header at the end of php code like :
header("location : registerd.php")
here is the whole code I'm writing Thank you very much in advance
