All done!

I really enjoyed this topic, and I think it can help a lot of us for future development, but beyond the topic there are soooo much more you can validate (validate if a email address entered is actually an email address ect) but this is just the beginning smiling smiley

Is it important to check user input on the server side with PHP too, when client side validation ( javascript ) is useful because it`s almost instantaneous and can alert the user to problem without making an unnecessary round -trip to the server ?

Done with the handbook, going through the chapter in the manual now, but I got the principles down.

Remembering to define the variables now, so things are going much better smiling smiley

Topic completed.

Validation is really important. Regarding HTMLSpecialChars, I'm glad that it's possible to keep any html entered in a form from messing up a webpage...

Done.

The counter ($counter) for validating inputs in 4B-1 can be risky if you have many inputs.

I used a boolean ($infocorrect) value which negates the "go-ahead" state if an error is detected.

<?php
.....
$infocorrect = true;

if (empty($firstname)) {
echo 'Please enter your first name.<br>';
$infocorrect = false;
}

...
if ($infocorrect) {
echo "Thank you for completing this survey $firstname.<br>";
...
}

?>

4B-2 - important!!

Yeah - until you have to save ASCII characters to a database with the intention to search the database for such characters..... arggh - don't ask me to explain. You NEVER stop learning PHP. Fun.
