Hi,

I have a problem, my knowledge’s about PHP is limited.

I use the 2.1 version of the Updownload module on PN .750 gold (http://www.petzi-juist.de/)

The module shows screenshots next to the downloads on the right site. I managed to move the screenshot to the left side with success. The only problem is if there is no images available it show noting. I traced down the piece of code responsible for this. Look at the following code:

File name: dl-util.php

//
//shows the screenshot
//thanks to: Luis Carlos Bethancourt
//
function get_screenshot($lid)
{
include("modules/UpDownload/includes/config.php");

echo "

<center>";
if($screenshotlink =="")
{
$screenshotlink = "modules/UpDownload/shots";
}

while($ext = current($screenshot_extensions))
{
if(file_exists($screenshotlink."/thumbs/$lid".$ext))
{
$fp = @fopen($screenshotlink."/thumbs/$lid".$ext,"r");
$small_ext = $ext;
}

if(file_exists($screenshotlink."/$lid".$ext))
{
$fp = @fopen($screenshotlink."/thumbs/$lid".$ext,"r");
$large_ext = $ext;
}
next($screenshot_extensions);
}

if ($fp)
{
if(file_exists($screenshotlink."/$lid".$large_ext))
{
// echo " $\""._FULLSCREENSHOT."\"$ $\""._FULLSCREENSHOT."\"$ / echo " $\""._SCREENSHOT."\"$ $\""._SCREENSHOT."\"$ ";

/* else
{
echo _NOPICTURE."
"._AVAILABLE ;
*/ }

echo"</center>

";
}

As you can see there is a second ELSE structure!!
When I un command the following lines I get a parser error

else
{
echo _NOPICTURE."
"._AVAILABLE ;
}

What’s wrong? How can I nest a IF then ELSE structure like this?

I hope somebody can shine some light on this, so I and others can learn from this.

Any help is appreciated,

Michiel

I think you need a '}' in front of the 'else' in error. As it stands you have an 'else' block that doesn't refer to any 'if'.
