  • In Random image ..should not appear twice on one page

    Thanks a lot for your reply big.nerd 🙂
    I understand the idea of that function, but I really don't have a clue how to implement. (way to much noob :eek: )
    Could you explain this more, if you have the time?

    Thanks very much,

    Dick

    • In Random image ..should not appear twice on one page

      This php scriprt will (as many other scripts ) pick an image from a parsed config file.
      In my "index.php" multiple images should show up (randomly picked).
      That all works perfect...but I do not want an image to show up twice (or even more) at the same time.

      How do I accomplish that?...I have no idea howto...

      Thanks

      Dick

      Here are the files:

      rotator.php

      function showImage() {

$ini_file = 'images.ini';
# read the config file into an array or die trying
$images = @parse_ini_file($ini_file,true);
if (! $images) {
  die('cannot read ini file');
}



$img = array_rand($images);
# get the selected image's css id if one exists
$id = $images[$img]['id'] ?
  sprintf( ' id="%s" ', $images[$img]['id'] ) :
  '';
# get selected image's dimensions
$size = @getimagesize( $images[$img]['src'] );
# if an url was specified, output the opening A HREF tag
if ( $images[$img]['url'] ) {
  printf(
    '<a href="%s" title="%s" target="blank">',
    $images[$img]['url'],
    $images[$img]['title']
  );
}
# output the IMG tag
printf(
  '<img src="%s" alt="%s" %s %s%s/ border="0">',
  $images[$img]['src'],
  $images[$img]['alt'],
  $size[3],
  $id,
  $class
);
# if an url was specified, output the closing A HREF tag
if ( $images[$img]['url'] ) {
  echo('</a>');
}	
  }
