That is a very good tutorial. Keep up the good work.
I'm running on an issue though. Whenever i click the submit button, i jump to an empty script.php page even if i insert 'wrong' data or even if i put the 'correct data without the messages being displayed.
How can i solve the issue ?
Thanks so much for the tutorial.

[@DigitalFox-tutorials]

Hey, this is not supposed to happen. Maybe you have a typo in your code, happens to me a lot.
Check out or download the source code from my website.

Why we use the null?

[@DigitalFox-tutorials]

You don't have to. When we create a variable without assigning a value, the variable by default has a value of null. Sometimes i set a variable to null, sometimes not. It depends on the moment i guess.

With bootstrap?

[@DigitalFox-tutorials]

No just HTML and CSS, no bootstrap here.

[@webdevolipment6107]

when i press submit my page is refreshing and then after refreshing is showing the message can you please help me

[@DigitalFox-tutorials]

That is because when you refresh the page you submit the form again.

Arrow code bad code?

[@DigitalFox-tutorials]

Hey, thanks for the sub. Can you be more specific please.

[@BlackCrypt]

@@DigitalFox-tutorials I’ve seen many tutorials where they say nested if then statements are bad.

[@DigitalFox-tutorials]

Nested if statements are not necessarily bad. It comes down on your
code readability. If your 'if else chains' are hard to follow , or you have
excessive nesting, then yes it's bad code because its harder to read and maintain your code.
I hardly use over two nested if statements in my code.

I get this problem in php file, value="" . I already have require in html and the script.php already has that variables. Please help

[@DigitalFox-tutorials]

Hey, if you already declared the variable in the php file, check for any misspelling.
Or download the source code:

[@SchulkenBorashen]

@@DigitalFox-tutorials Thanks for replying! I checked the variables, it is the same. I also looked at the source code, I added the terminator but the problem's still there. This is a project for my school so it is a little bit different from your tutorial. The form I made has an action=" ". Maybe that's the problem?

[@DigitalFox-tutorials]

@Schulken Borashen It doesn't matter if the action attribute is empty, check in the php file if your variables are declared outside the if statement, and not inside.
