PHP Message Box

[sseeley]

Hi I am new to PHP can anyone tell me whether I can generate a message box just using PHP?  If you have some sample code that would be great.

 

Many thanks in advance.

elaborate more please. What do you mean by a message box?

 

PHP can generate HTML, so thereby you can use PHP to generate an HTML box.

 

What are you looking for?

I am just looking for a message box that displays errors for example when a user enters a password that is not the correct length.  'Your password must be at least 8 characters long'.

 

Thanks

in that case all you need is a set of if,else statements

<?php
if(strlen($_POST['password'] < {
echo('Your password must be at least 8 characters long');
}
else{
echo('GOOD JOB!');
}

For a Message Box, I think you will want to use Javascript.

I would have to agree with this post for some realtime checking you would need to use AJAX (JavaScript) with PHP used as the called page. There should be some examples of this around the net.

also if you make something in javascript that check the length a password you need to rerun the check in php again before you insert it into the database. because javascript checks can be easily bypassed.
