Removing posted info

Maleko

ok, on my guestbook, when they fill out there website link, if they just put www.domain.com that works fine, if they put [url]http://www.domain.com,[/url] another [url]http://[/url] is added to that post, making the link no work...how can i get it to remove the [url]http://[/url] if the user manually submits it?

in the post section of the guestbook try this. we will call the form field where they enter their website, url for the sake of this code.

if(substr($POST['url'], 0, 7) == "http://") {
$POST['url'] = substr($_POST['url'], 7); //start the string after [url]http://[/url]
}

that one simple if statement will remove their [url]http://[/url] if they put it in, otherwise it will just continue processing as it does now. give that a shot and see how it works.

ive been inserting it in all places in my codes...doesnt do anytihng...

you need to change url in $_POST['url'] to whatever the name of the text field is in the guestbook script, otherwise it will do nothing.

Maleko

yeh, i did, where do i put the script exactly?

drew010

can you maybe paste some of the guestbook code? all of it if its one file.

Well, heres my process file:

//Database connection
	$user="";
	$host="";
	$password="";
	$database = "";
//If fail to connect, error
	$connection = mysql_connect($host,$user,$password)
			or die ("Couldn't connect to server");
	$db = mysql_select_db($database,$connection);
//Insert information submitted into database
		$date = Date("y-m-d H:i:s");
		$query="INSERT INTO guestbook (name,email,url,message,dateadded) VALUES
			('$name','$email','$url','$message','$date')";
//If cant insert data, error
	$result=mysql_query($query)
		or die ("Couldn't execute query");

echo "just a message to redirect"

That file is processed once the user clicks cubmit, then it redirects to the gustbook entries...im still working out how to use if and else to make it one file.

ok the reason its probably not working is because of register_globals conflict.

change your code to this:

$date = Date("y-m-d H:i:s");

if(substr(strtolower($url), 0, 7) == "http://") {
$url = substr($url, 7);
}

$query="INSERT INTO guestbook (name,email,url,message,dateadded) VALUES
('$name','$email','$url','$message','$date')";

hope that does it.

Sweet, works fine 😃 cheers for the help!

Would u be able to explain what does what in the code?

if(substr(strtolower($url), 0, 7) == "http://") { 
$url = substr($url, 7); 
}

if (the first seven letters (of the url, in lower case) == "http://") {
the url = every thing after that
}
