I need help modifying this script so that the URL field be a simple Title field.  Right now the URL field cheks if it is properly inputed and if it contains spaces or you leave out .com then it shows error.  I just need this simple fix to remove those rules so that this field can be used as title.  Any help is appreciated.

 

I pasted the file below

 

<?php
if(preg_match('#' . basename(__FILE__) . '#', $_SERVER['PHP_SELF'])) { die('You are not allowed to call this page directly.'); }

Thank man that worked.  I noticed a second problem now the script still outputs Title as URL.

It shows title URL icon, and when you move mouse over it shows the http://title

 

I just want it to output pure title.

 

Let me know if you can help

 

Thanks

 

I think this is the code in the same file.

 

// add slash if ip is visible

if($var_show_ip==1) {

$slash=" / ";

$part1=explode(".", $dbresult->ip);

$part2=explode(".", $options["ip_mask"]);

if($part2[0]=="*") {$part1[0]=str_repeat("*", strlen($part1[0]));}

if($part2[1]=="*") {$part1[1]=str_repeat("*", strlen($part1[1]));;}

if($part2[2]=="*") {$part1[2]=str_repeat("*", strlen($part1[2]));;}

if($part2[3]=="*") {$part1[3]=str_repeat("*", strlen($part1[3]));;}

$show_ip = $part1[0] . "." . $part1[1] . "." . $part1[2] . "." . $part1[3];

} else {

  $show_ip=""; $slash="";
