Removing Particular Text From Field - PHP - HELP!

[oliverj777]

Hello,

 

I have a field in which when a user types something into it, it saves it into a table in my SQL. But is it possible to remove a particular phrase from the field if the user enters it.

 

Example:

 

I have a text field that says 'please enter your website domain here'. The user then enters 'www.domain.com'. Is it possible for PHP to remove the 'www.' and only save the 'domain.com' to my SQL (bearing in mind that not all users may enter www.)

 

Here is the code for the text field:

 

<input name="website_name" type="text" class="text-box" id="website_name" value="<?php echo $website_name; ?>" size="24" />

 

Here is the code for the _POST:

 

if(isset($_POST['send']))
            {
		$database->updateUserField($session->username, "website_name", $_POST['website_name']);	
}

 

(the code so far all works fine - I just want to add an extra 'variable', if you will, to the code)

 

Thanks for your help!!

$website_name = str_replace('www.', '', $_POST['website_name']);

I would test this but my FTP application keeps crashing  :confused: -- It looks like it would work. For future reference, would that code search any text for 'www.' For example, if some user types in 'hellowww.' will that code also remove the 'www.' no matter where it is within the text, thus saving it as 'hello'?

 

Thanks

Yes.

I tested it - and it didn't work -- any suggestions?

 

It still saves the www. into my SQL table??

This is my code so far:

 

 if(isset($_POST['send']))
            {
		$website_name = str_replace('www.', '', $_POST['']);
		$database->updateUserField($session->username, "website_name", $_POST['website_name']);

Well, you'll either need to change:

 

$website_name = str_replace('www.', '', $_POST['website_name']);
// to
$_POST['website_name'] = str_replace('www.', '', $_POST['website_name']);

 

Or change:

 

$database->updateUserField($session->username, "website_name", $_POST['website_name']);
// to 
$database->updateUserField($session->username, "website_name", $website_name);	

 

One or the other.  Thought that would be obvious, sorry.

sweet --

 

I used the

$_POST['website_name'] = str_replace('www.', '', $_POST['website_name']);

 

works fine
