I have the following php script that was taken from http://ma.tt/scripts/randomimage/ . I want to use this extensively in an HTML page so I turned the script into a basic function so I could add a parameter to it, as to make it more flexible. My question is, now that I edited the parameter into the script, how can I specify this parameter within the HTML page?
Heres the Script:
<?php
function previewImage($directory){
$folder = $directory;
// Space seperated list of extensions, you probably won't have to change this.
$exts = 'jpg jpeg png gif';
$files = array(); $i = -1; // Initialize some variables
if ('' == $folder) $folder = './';
$handle = opendir($folder);
$exts = explode(' ', $exts);
while (false !== ($file = readdir($handle))) {
foreach($exts as $ext) { // for each extension check the extension
if (preg_match('/\.'.$ext.'$/i', $file, $test)) { // faster than ereg, case insensitive
$files[] = $file; // it’s good
++$i;
}
}
}
closedir($handle); // We’re not using it anymore
mt_srand((double)microtime()*1000000); // seed for PHP < 4.2
$rand = mt_rand(0, $i); // $i was incremented as we went along
header('Location: '.$folder.$files[$rand]); // Voila!
}
?>
