Does anyone know a code to have a random image display in the directory?

PHP Code:


			
<?php 

/// Set $dirname to your full path

$dirname = $_SERVER['DOCUMENT_ROOT']."/image_folder/"; // Include trailing slash

/// End config

$i = 0;

$pics = array();

$dir = opendir( $dirname );

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

    if( !is_dir( $file ) ){

        $pics[$i] = $file;

    }

    $i++;

}



$max = count( $pics ) - 1; 

$rand = rand( 0, $max ); 

echo( '<img src="'.$pics[$rand].'" alt="banner" />' ); 

?>

Should do the trick nicely for you...

In case you have files in your image directory that aren't images:

PHP Code:


			
<?php

$dir = ''; // Set this to your image directory relative to the script, or leave blank

foreach(glob($dir.'*') as $image) {

  switch (strtolower(substr($image,-3))) {

  case 'jpg':

  case 'png':

  case 'gif':

    $images[] = $image;

    break;

  }

}

shuffle($images);

echo '<img src="'.$images[0].'" alt="A Random Image"/>';

?>

ghostcop: what about *.tiff? or *.jpeg even? Unlikely, yet possible.

To add an extension to the php code I wrote, simply add a

PHP Code:


			
case 'ext':

above the case 'jpg': where ext is the extension of the file type. Removing any of the existing case statements will prevent that file type from being displayed.
