Dynamic PHP Picture Viewer HELP!!!

whatsthis

I'm playing with the Dynamic PHP Picture Viewer from javascriptkit.com.

The PHP file is put into the same folder as the images to pass the array to the javascript.

Does any one know how to change this PHP script so I can enter the folder. I want to get the folder from mysql table to tell the picture viewer which pictures to show.

<?
Header("content-type: application/x-javascript");
$pathstring=pathinfo($SERVER['PHP_SELF']);
$locationstring="http://" . $SERVER['HTTP_HOST'].$pathstring['dirname'] . "/";

function returnimages($dirname=".") {
$pattern="(.jpg$)|(.png$)|(.jpeg$)|(.gif$)";
$files = array();
$curimage=0;
if($handle = opendir($dirname)) {
while(false !== ($file = readdir($handle))){
if(eregi($pattern, $file)){
echo 'picsarray[' . $curimage .']="' . $file . '";';
$curimage++;
}
}
   closedir($handle);
}
return($files);
}

echo 'var locationstring="' . $locationstring . '";';
echo 'var picsarray=new Array();';
returnimages()
?>

I've tried changing the dirname variable

Thanks all

Are you using an url or a relative path? Either way, use a relative path from the sever root and see if it works.

Thanks for your reply Vaaaska but I'm a bit wet behind the ears and shall need a bit more guidance.

I want to put this getpics file with the javascript slideshow in the same folder on my website. The different folders of images are also on my server. I need the getpics.php file to get the folder name from mysql table (that I can do) but then it needs to send the array to the javascript. I've found this but haven't tried (played) with it yet.

<?php
// getpics.php
$directory = "Graphics/Thumbnails"; // Directory in which the images are stored, relative to the location of this script. Must have the slash
header("Content-Type: text/javascript");
$dir = opendir($directory);
for($i=0;$file = readdir($dir);$i++)
if(strpos($file, ".") === 0) {
$i--;
continue;
} else echo("fadeimages[$i]=['$directory/$file', '', ''];\n");
?>

any help greatly appreciated.

The problem is likely your directory...you need the entire root. Put this at the beginning of the file and tell us what you get.

echo $_SERVER['DOCUMENT_ROOT']; exit;

Thanks for your help Vaaaska,I've got ithe bloody thing working now. The script creates an array and then populates it with images from a folder. The folder path comes from the mysql table.

Works great and I can call the php script from the javascript page but I can't integrate the php and the javascript scripts into dreamweaver. I'm sending the mysql info for the select/from/where to the php page which gets the folder path. The array is then created and populated but I want to display the javascript html page with the slideshow on it.

I think that I need to embed the php script into the javascript page. Or even better get the php page to call the javascript. I don't know and getting confused !
