Hi, i have found the following code which works fine for two images but i am having problems adding adding more data to the array and displaying a third different image.

Please can someone tweak the code below to help me?

Kindest regards,

Brian

<?php
$images = array(0 => array ('portfolio/index.php','Qlink.gif'), 1 => array ('news.php','Qlink2.gif'), 2 => array ('fountain.php','Qlink3.gif'), 3 => array ('castle.php','Qlink4.gif'));
$imageone='';
$imagetwo='';

function create(){
$chosen = array();
global $imageone, $imagetwo;
$i='1';
while ($i <= 2){
$random = rand(0, 3);
if (!in_array($random, $chosen)){
array_push($chosen, $random);
$i++;
}
}
$imageone = $chosen['0'];
$imagetwo = $chosen['1'];
}
create();
?>

Then call it like this

<a href="<?php echo $images[$imageone][0]; ?>" title="link to page"><img src="default_image_folder/<?php echo $images[$imageone][1]; ?>" alt="random image and link" /></a>

Hi

I would prefer to use the array_rand() function :

CODE --> PHP ( fragment )

function create()
{
  global $images;
  $chosen = array_rand($images, 2);
  shuffle($chosen);
  return $chosen;
}

list($imageone, $imagetwo) = create();

Actually that is more useful with associative arrays :

CODE --> PHP

<?php
$images = array(
  'portfolio/index.php' => 'Qlink.gif',
  'news.php' => 'Qlink2.gif',
  'fountain.php' => 'Qlink3.gif',
  'castle.php' => 'Qlink4.gif'
);

function create()
{
  global $images;
  $chosen = array_rand($images, 2);
  shuffle($chosen);
  return $chosen;
}

list($imageone, $imagetwo) = create();
?>



<a href="<?php echo $imageone; ?>" title="link to page"><img src="default_image_folder/<?php echo $images[$imageone]; ?>" alt="random image and link" /></a>

However I see no reason why those dumb $imageone and $imagetwo variables are used.
