Hi there i was just wondering whether anyone knew why this code wont work when i try and open a certain Directory on my virtual homespace.

Code:

<?php 


	$handle=opendir("."); 
	$strSought = "gif"; 
	$imgCount = 0;  

	while ($file = readdir($handle)) 
	{ 
		if ($strSought == substr($file, -3)) 
		{ 
		    $imgCount = $imgCount + 1; 
		} 
	} 

	closedir($handle);

	if ($imgCount != 0)
	{
		$handle=opendir('.'); 

		$perRow = 5;

		$numRows = $imgCount/$perRow;

		$imgNum = 0;

		echo "<table width=\"100%\" border=\"0\">"; 

	 	//Note: readdir returns filenames in the order in which they are 
	 	//    stored by the filesystem. Future enhancement: sort by filename 
	 	//    (sequence they were shot) 
	 	
	 	while (false !== ($file = readdir($handle))) 
	 	{ 
			if ($strSought == substr($file, -3)) 
			{ 
			    $imgNum++;

			    $size = GetImageSize($file); 

			    $jpglink = substr($file, 0, 8);

			    echo "<td><a href=\"$jpglink.jpg\"><img src=\"$file\" height=\"$size[1]\" width=\"$size[0]\" border=\"1\" hspace=\"10\" vspace=\"20\"></a>";						

			    //modulus (%) $a % $b remainder of $a divided by $b 
			    if ($imgNum%$perRow)
			    {
				echo "</td>";
			    }
			    else							
			    {
				echo "</td></tr><tr>";
			    }
		 	 }
	  } 

	 closedir($handle); 
	 echo "</table>"; 
  }

?>

When i change the $handle=opendir("."); to $handle=opendir("/chosen/directory");
I keep getting an error

Does anyone have a solution please?

Could you post the error, please?

Add a dot or remove the first slash from the directory. This should work.

PHP Code:

$handle=opendir("./chosen/directory"); 



// or



$handle=opendir("chosen/directory");

Hi guys thanks a lot for this it works really well indeed except i have one slight problem and that is when i create sepreate pages for the users eg. nico.php and sarah.php... no matter which of those two users I am logged in as I am still able to access both the user pages...

so for example, if i log in as nico i get redirected to nico.php page. but i am able still to access sarah.php... just by the simple fact that i am a logged in user

I hope this makes sense
can anyone help me with this??

thanks

Sounds like you need to add some code to track who is logged in and restrcit them from accessing pages they aren't allowed to view.

Or dynamically generate your pages based on what user is logged in, the way it's supposed to be done
