Hi!
I have a randomscript which both makes a random image from a folder and creates a random class. Sometimes it duplicates the images and my question is:
How do I make the images to just be displayed once?
the script is:
<?php
/* The default folder with images */
//$settings['img_folder'] = 'plugins/project_menu/images/thumbs/';
/* File types (extensions) to display */
$settings['img_ext'] = array('.jpg','.gif','.png');
/*
How to display the images?
0 = print just the image path (for includes), like: images/test.jpg
1 = redirect to the image, when using: <img src="randim.php" />
*/
$settings['display_type'] = 0;
/* Allow on-the-fly settings override? 0 = NO, 1 = YES */
$settings['allow_otf'] = 1;
/*******************************************************************************
* DO NOT EDIT BELOW...
*
* ...or at least make a backup before you do!
*******************************************************************************/
/* Override type? */
if ($settings['allow_otf'] && isset($_GET['type']))
{
$type = intval($_GET['type']);
}
else
{
$type = $settings['display_type'];
}
/* Override images folder? */
if ($settings['allow_otf'] && isset($_GET['folder']))
{
$folder = htmlspecialchars(trim($_GET['folder']));
if (!is_dir($folder))
{
$folder = $settings['img_folder'];
}
}
else
{
$folder = $settings['img_folder'];
}
/* Make sure images fodler ends with an '/' */
if (substr($folder,-1) != '/')
{
$folder.='/';
}
/* Get a list of all the image files */
$flist = array();
foreach($settings['img_ext'] as $ext)
{
$tmp = glob($folder.'*'.$ext);
if (is_array($tmp))
{
$flist = array_merge($flist,$tmp);
}
}
/* If we have any images choose a random one, otherwise select the "noimg.gif" image */
if (count($flist))
{
$src = $flist[array_rand($flist)];
}
else
{
$src = 'noimg.gif';
}
/* Output the image according to the selected type */
if ($type)
{
header('Location:'.$src);
exit();
}
else
{
// echo $src;
}
?>
and for calling the images (the long scripts is because I got 25 pictures that is displayed):
<body>
<?php
// This is for making a random class
class UniqueRand{
var $alreadyExists = array();
function uRand($min = NULL, $max = NULL){
$break='false';
while($break=='false'){
$rand=mt_rand($min,$max);
if(array_search($rand,$this->alreadyExists)===false){
$this->alreadyExists[]=$rand;
$break='stop';
}else{
// echo " $rand already! ";
// print_r($this->alreadyExists);
}
}
return $rand;
}
}
$rand=new UniqueRand();
?>
<?php
/* this is for making a random image from the folder
plugins/project_menu/images/thumbs/ hyperlinked to
plugins/project_menu/images/pictures/ */
$_GET['type']=0;
$_GET['folder']='plugins/project_menu/images/pictures/';
// new random image1;
include 'randim.php';
//now you have large image in $src;
// replace folder name assuming filename is the same
$small = str_replace('plugins/project_menu/images/pictures/','plugins/project_menu/images/thumbs/',$src);
?>
<ol>
<li><div class="scrollbox">
<div class="<?="randompacering". $rand->uRand(1,25).""?>"><a class="fancy" rel="fancy" href="<?=$src;?>"><img border='0' height='40px' src="<?=$small;?>"></a></div></p>
</li>
<?php
// new random image2;
include 'randim.php';
$small = str_replace('plugins/project_menu/images/pictures/','plugins/project_menu/images/thumbs/',$src);
?>
<li>
<div class="<?="randompacering". $rand->uRand(1,25).""?>"><a class="fancy" rel="fancy" href="<?=$src;?>"><img border='0' height='40px' src="<?=$small;?>"></a></div></p>
</li>
</ol>
</body>
</html>
any suggestions?
thanks a lot!
