I want to do a random image block with selected images which then link to certain URLs.
I found one script which works on a regular page on my server, have a look here.
But when I add this (and the corresponding phpblock) as a function to lib-custom like this:
PHP Formatted Code
function phpblock_random()
{
$file_type = ".jpg";
$text_file_type = ".txt";

$image_folder = "images";

$handle = opendir("/xxx/x/duvide.com/public_html/random/$image_folder");
while ($file = readdir($handle))
        $names[count($names)] = $file;
closedir($handle);

sort($names);

for ($i=0;$names[$i];$i++){
        $ext=strtolower(substr($names[$i],-4));
        if ($ext==".jpg"){
                $names1[$tempvar]=$names[$i];$tempvar++;
                }
        }

$random = mt_rand(1, $tempvar);

$image_name = $random . $file_type;
$text_name = $random . $text_file_type;

}
// end random

The block is not showing at all, not even an error message.
Any ideas?

Thank you/Frank

Geeklog has 2 image gallery plugins each of which have imageblock functionality BTW.

if you are in the know, please tell me the code I need in order to get it running. I am not a php guy, in case you have not noticed.
I know there are image galleries but their random blocks don't do what I need.

Thank you

A PHP block should return the HTML that Geeklog will then display in the block. However, the above code doesn't really do anything from what I can see. So it's not only the missing return statement - it's not clear what that code is supposed to do in the first place ...

bye, Dirk

it should do what it does on this link but in a block in geeklog:
with each refresh it changes the images randomly. Very simple I would think.

Thanks for your help/Frank

My G2Bridge for Gallery2 allows for the use of my Minislideshow or MediaBlock or even autotags to accomplish your goal.

Wondering if I got enough urls in there Wink

Oops sorry almost forgot about you.
try:
PHP Formatted Code

    function phpblock_random_images() {
        global $_CONF;
        $image_directory = '/images/';
        $link = $_CONF['site_url'];
        $pattern = ".jpg$";
        $files = array ();
        $display = '';
        if ($handle = opendir($_CONF['path_html'].$image_directory)) {
            while ($file = readdir($handle)) {
                if (eregi($pattern, $file)) {
                    $files[] = $file;
                }
            }
            shuffle($files);
            $file = $_CONF['path_html'].$image_directory.$files[0];
            list ($width, $height, $type, $attr) = getimagesize($file);
            $display .= '<a href="'.$link.'"><img src="'.$_CONF['site_url']
                .$image_directory.$files[0].'" '.$attr
                .' alt="'.$files[0].'" title="'.$files[0].'"></a>';
            closedir($handle);
        }
        return $display;
    }

Thank you for your effort -s.
But this is not the script I need to incorporate into the block.
Why is my script working on a normal page but not in the geeklog blog? That is would I would like to solve.

the code for the linked page is like this:
PHP Formatted Code
<?php include "/xxx/x/duvide.com/public_html/random/random.php";
echo "<img src=\"$image_folder/$image_name\" alt=\"$image_name\" />";
include "$image_folder/$text_name"; ?>

like I said, I am not the php guy, maybe something needs to be added to the code for the block?

Hi -s, it works but not like I need it to work. I want only certain images displayed randomly linking to a certain URL and I want a caption. My standalone script does this and I just would like to have it in a block. Is this too much to ask for Big Grin

Thanks/Frank
