2 Questions, Just finding the correct functions

[Lamez]

Question 1:

I am working on a external link checker, but If the user does not add a protocol like http:// or ftp:// or something like that how can I add it to the beginning of the URL?

Example:

-User input: www.google.com

-Code Added: http://www.google.com

 

Question 2

How can I find the address the user came from?

 

-Thanks guys!

1.

 

<?php
$form = array('url');
if ($form['url'] != '' && strpos(strtolower($form['url']), 'http://') !== 0)
$form['url'] = 'http://'.$form['url'];
?>

 

2. php referrals - google a script or something

I am sorry, but the code you gave me does not echo anything out.

 

Here is how I integrated it.

<?php
$url = htmlspecialchars($_GET["url"]);
$form = array($url);
if ($form['url'] != '' && strpos(strtolower($form['url']), 'http://') !== 0)
$form['url'] = 'http://'.$form['url'];
$url = $form['url'];

if (!isset($_GET["url"])){
header("Location: http://www.krazypicks.com");
}else{
echo "<center>You are about to leave KrazyPicks! to an external link. <br>Do you want to continue?";
echo "<br>External Link: ".$url."</center>";
?>

 

Thanks!

Sorry bout' that, didn't include the output 

 

Well it's good that you took it upon yourself to figure it out. Glad I could help, half way atleast.

see that is the thing, I get nothing echoed out!

 

you can test the code here: http://links.krazypicks.com/?url=google.com

Try it? The values in the array() shouldn't return anything because they weren't extracted. Should work now.

 

Ugh, man it's 3 am here, and I'm tired. Forgive me for my stupidity.

 

But keep in mind that this quick little fix up will always add http://, it does not interpret the protocol beforehand.

 

Although, I'm not quite sure why you would want to worry about ftp://, etc...?

 

This function should interpret it though, so just incorporate it where necessary. Unless it's for the active protocol only. *shrug* If none of this helped you, I'm sure someone else can. I gotta get some rest, and I'll help you more in the morning if your problem is still unresolved.

 

Good luck.

Thank you for that little bit of code, it was exactly what I was looking for.

 

Thanks Again!

I thought there was a way to find out where the user came from.

 

Example:

User googles my website, but I redirect them back to the google search.

 

Any way?
