strange... the code looks okay to me. Maybe start commenting out blocks of code to narrow down where the problem is occurring?

Hi Nonshatter, I have included form html and the below php code and there is no output at line 28. I am using WAMP and I have also uploaded it to the my domain and still the code is displayed on screen?

Really puzzling me now

Cheers

David

<?php
//current.php
 
if (isset($_POST['submit'])){
   $title = $_POST['title'];
 
 
   //Here I'm spliting the title variable to see what the first two letter are
   $titleSplit = str_split($title, 2);
 
   if($titleSplit[0] == 'tt'){
      $url = 'http://www.imdb.com/title/' . $title;// $title value expected tt0892318
	  $title = $url;
   }
   elseif($titleSplit[0] == 'ht' ){
 
	  $title = $url;// $title value expected http://www.imdb.com/title/tt0892318
   }
   else
   {
      $url = 'http://www/imdb.com/title/tt' . $title;// title value expected tt0892318
	  $title = $url;
 
   } 
 
}
echo $title;
?>

Hi Nonshatter, I have started to get this to work again by rebuilding the page. Now one of the problems is that the only statement that is working is the 1st if and elseif and else don't provide any value outputs at all? I have placed a number of echo statments throughout the script to test this

I am not sure if you or anyone has any ideas

Thanks in advance

David

<?php
if (isset($_POST['submit'])){
   $title = $_POST['title'];
 
 //echo $title;// Test expected string output ok
 
 $titleSplit = str_split($title, 2);
  
  
   if($titleSplit[0] == 'tt'){
      $url = 'http://www.imdb.com/title/' . $title;// $title value expected tt0892318
	  $title = $url;
	  echo " this should be tt", $title;
   }
   elseif($titleSplit[0] == 'ht' ){// This could also search ww to enable the programmer to ommit the HTTP:// element of the url
     
	  $title = $url;// $title value expected http://www.imdb.com/title/tt0892318
	   echo " this should be ht", $title;
   }
   else
   {
      
	  $url = 'http://www/imdb.com/title/tt' . $title;// title value expected 0892318
	  $title = $url;
	   echo " this should be 08", $title;
   } 


}


echo $title;
 ?>
