photo gallery doent work WHY

**big-dog1965** · 09-10-2007, 11:13 AM

Can someone tell me why this dont work. I down loaded a photo gallery from
http://www.dynamicdrive.com Here the getpics.php is said to save in the gallery folder I did that (also it automaticly makes a getpics.php. file that keeps coming back even if you delete it?)

PHP Code:


<?

Header("content-type: application/x-javascript");



function returnimages($dirname=".") {

   $pattern="\.(jpg|jpeg|png|gif|bmp)$";

   $files = array();

   $curimage=0;

   if($handle = opendir($dirname)) {

       while(false !== ($file = readdir($handle))){

               if(eregi($pattern, $file)){

         $filedate=date ("M d, Y H:i:s", filemtime($file));

                 echo 'galleryarray[' . $curimage .']=["' . $file . '", "'.$filedate.'"];' . "\n";

                 $curimage++;

               }

       }



       closedir($handle);

   }

   return($files);

}



echo "var galleryarray=new Array();" . "\n";

returnimages();

?>

Heres the htm page

HTML Code:

Well, I checked the URL:

PHP Code:


http://www.wichita.com/gallery/getpics.php

and there was nothing there, or it wouldn't allow me to see it.

Anyways, there could be any number of problems. If the server isn't PHP enabled, this script will not work. If it uses a proprietary PHP syntax, the getpics.php would need to be modified for that syntax. If it follows strict PHP syntax, there are two modifications (red) that may need to be made:

Code:

<?php
Header("content-type: application/x-javascript");

function returnimages($dirname="./") {
   $pattern="\.(jpg|jpeg|png|gif|bmp)$";
   $files = array();
   $curimage=0;
   if($handle = opendir($dirname)) {
       while(false !== ($file = readdir($handle))){
               if(eregi($pattern, $file)){
		 $filedate=date ("M d, Y H:i:s", filemtime($file));
                 echo 'galleryarray[' . $curimage .']=["' . $file . '", "'.$filedate.'"];' . "\n";
                 $curimage++;
               }
       }

       closedir($handle);
   }
   return($files);
}

echo "var galleryarray=new Array();" . "\n";
returnimages();
?>

Only one or the other of the above modifications may be needed, or they both may, or neither.

To be of much more help, we would need a link to the problem page.

Please post a link to the page on your site that contains the problematic script so we can check it out.

test
basicly just the gallery page

**jscheuer1** · 09-10-2007, 06:59 PM

You forgot to close the style tag:

Code:

<style type="text/css">

.slideshow{ /*CSS for DIV containing each image*/
float: left;
margin-right: 10px;
margin-bottom: 10px;
}

.slideshow img{ /*CSS for each image tag*/
border: 0;
width: 200px;
height: 106px;
}

#navlinks{ /*CSS for DIV containing the navigational links*/
width: 400px;
}

#navlinks a{ /*CSS for each navigational link*/
margin-right: 8px;
margin-bottom: 3px;
font-size: 110%;
}

#navlinks a.current{ /*CSS for currently selected navigational link*/
background-color: yellow;
}
</style>
</head>

And:

Code:

<script src="http://www.wichitarcraceway.com/test/gallery/getpics.php" type="text/javascript"></script>

is a file not found error.

Sorry amiture misstakes there oh wait Iam

I got that fixed. Now the pics try to come up but just see X but looking at properties of X it has image name

Never mind on X I needed a locaction for link back to itself
Seems rather slow but works.
Thanks again

Seems rather slow but works.

2007_Free_Race2.jpg at 1.2 MB (1,243,150 bytes)? Come on.

If you were to resize and optimize your images they would come up much faster. This script also allows you to use two directories, one for thumbnails and one for larger images. If you were to make small optimized images for the thumbnail directory and larger optimized versions for the larger images directory, it would load very fast and each larger image would take little time to load as well.

**big-dog1965** · 09-11-2007, 07:50 AM

I spent some time looking for a script to resize but the ones I found I didnt know how to make them work and seemed that most just done jpg. It would be nice to have one that would resize what ever was put into a folder jpg, png, gif then make another some % smaller and put that into another folder.
