[SOLVED] Lowercase only

[NoDoze]

I have a PHP form, which when entered into the mysql database, I only want to be lowercase characters only, possible?

[NoDoze]

Hmmmm....ok.... I think I'm closer, but still don't understand....

 

This is from my code:

$user_id = $_POST['user_id'];

 

How would I apply this to it?

$string = "This-Is An! Example234";

$string = preg_replace('/[^0-9a-z]*/','',strtolower($string));

 

Would it be...?

$user_id = preg_replace('/[^a-z]*/','',strtolower($_POST['user_id']));

 

Thanks!

$user_id = $_POST['user_id'];
$user_id = strtolower($user_id);

This is used in a form, so wouldn't I still need to use 'POST' to define the variable?

 

Or would that do both tasks?

What do you mean?  My code does use $_POST.  This code is assuming the user hits 'submit' and the form is submitted to the processing page/script.  With $_POST all you do is call the name of the input field.  So if you have:

 

 

Then you would get the submitted information by calling...

 

$user_id = $_POST['NoDoze'];

 

Is this what you're asking or helpful?

Oh! Woops....

You're talking about putting BOTH lines....Ahhhh!

I was thinking you meant replace the first with the second...

 

Sorry for the misunderstanding! heh.

 

Thanks!

No worries.  I haven't tested that code but I'm pretty sure it will work.

[NoDoze]

Worked perfectly!

 

But now I realize I have another problem... the same variable is creating the user folder too!

 

So...

mkdir ("/home/dir/dir/ftp/{$_POST['user_id']}")

is creating the directory with the mixed caps.

 

how would I alter this to take lowercase only?

mkdir ("/home/dir/dir/ftp/$user_id")

So that it would take the defined variable from above instead in lowercase?

 

Thanks

You want the directory path to use the lowercase string?

 

mkdir ("/home/dir/dir/ftp/".$user_id."")

[NoDoze]

Yup! I'll give that a try...

 

Thanks!

[NoDoze]

Worked like a charm!

 

Thanks!

No problem, glad I could help.
