[Short-URL]

Okay, I have my website http://www.small-url.com

But I cant seem to figre out stopping someone signing up as there shorturl with a slash or a dot, becuase that causes errors

Any ideas?

[trq]

[code=php:0]
if (strpos($shorturl,array("/",".")) {
  echo "your shorturl cannot contain slashes or full stops";
}
[/code]

you should sort the error out ok.

when the error is sorted the example below to valadate url good luck.


sorry there you go you can have http:// or www. or both lol full url or subdomain

[code]
Code:
<?

//tempary web address.

$web_address="www.google.com";

function web_address($web_address) {

if(eregi("^(http://|www.)+[a-z]+\.+[a-z]+(\.+[a-z]{2})?$",$web_address)){

echo "Correct web address!";
}else{
echo "Wrong web address!";
}
}

//returning the function.

web_address($web_address);


?>
[/code]

Still nothing..

if (strpos($shorturl,array("//","."))[color=red][b])[/b][/color] {

you missed a bracket off the end.. so I added it on but it still doesnt work.

Hello,

I have tried using the above, but it still lets me signup with a dot or a slash.

What charaters you consider as valid? Only alphanumeric? Or other stuff too?

Orio.

alphanumeric.

Use:
[code]<?php
if(!ereg("^[a-zA-Z0-9]+$", $url)){
die("Invalid url");
}
?>[/code]

Orio.
