Click on image.

[zhanna]

Hello,

 

I am facing a problem and i can't solve it.

What my code do?

It automatically loads an image from a folder randomly on any page i wish, i specially use it for banners.

 

In pages i placed, size is witdh 200 and height 200, but real size is not 200/200. All i want is the image loaded should be clickable to view full size of it.

 

My Code:imgs.php

<?

error_reporting(0);

if ($handle = opendir('files')) {

 

  $count=0;

  /* Dit is de juiste manier om door een directory te wandelen. */

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

if(getimagesize("files/".$file)) {

$count++;

      $dirlist[$count]="files/".$file;

    }

  }

 

  closedir($handle);

  $filenr = rand(1,$count);

  print($dirlist[$filenr]);

 

}

?>

 

Then i use this small script to show in my pages.

 

<img src="<? include("imgs.php"); ?>" cellpadding="0" width="200" height="200">

 

this will load a random image from imgs.php with size of 200/200, All i want is, i want the images to be clicable, if i click on them, i see full size of the images.

 

please  Can anyone of you help me ?

 

Thanks

are you wanting the full sized image to be on a page all by itself? Just wrap a url tag around it with it as the target.  Are you wanting some kind of popup thing? You're gonna have to use javascript for that.

You would be better off making it a function then assigning the random picture name to a variable so it will be clickable.

 

<?php
error_reporting(0);
function get_pic(){
  $dir = "files";
  if ($handle = opendir($dir)) {
  $count=0;
  /* Dit is de juiste manier om door een directory te wandelen. */
    while (false !== ($file = readdir($handle))) {
      if(getimagesize("$dir/".$file)) {
      $count++;
      $dirlist[$count]="$dir/".$file;
      }
    }
  closedir($handle);
  $filenr = rand(1,$count);
  return ($dirlist[$filenr]);
  }
}

$pic = get_pic();

echo "<a href=\"$pic\" /><img src=\"$pic\" cellpadding=\"0\" cellspacing=\"0\" width=\"200\" height=\"200\" /></a>\n";
?>

Thank You Ray.

 

but one more problem, i did use the way you mentioned.

 

I made a table, it has 4 row and 4 column.

 

In each row, i added this code.

<? echo "<a href=\"$pic\" /><img src=\"$pic\" cellpadding=\"0\" cellspacing=\"0\" width=\"150\" height=\"150\" /></a>\n"; ?>

 

As i refresh, i am getting same images everywhere. i have 8 image in one page, all images are same. I want them random.

 

Is it possible to show random images with one function ?

you would need to either call the function 8 times or change the function to give you 8 images in an array. Personally I would store the 8 images in an array then call them from the array.

 

<?php
error_reporting(0);
function get_pic(){
  $dir = "files";
  if ($handle = opendir($dir)) {
  $count=0;
  /* Dit is de juiste manier om door een directory te wandelen. */
    while (false !== ($file = readdir($handle))) {
      if(getimagesize("$dir/".$file)) {
      $count++;
      $dirlist[$count]="$dir/".$file;
      }
    }
  closedir($handle);
  for($i=0; $i<8; $i++){
  $filenr = rand(1,$count);
  $images[] = $dirlist[$filenr];
  }
  return $images;
  }
}

$pics = get_pic();
// now your 8 images would be this
echo "<a href=\"".$pics[0]."\" /><img src=\"".$pics[0]."\" cellpadding=\"0\" cellspacing=\"0\" width=\"200\" height=\"200\" /></a>\n";
echo "<a href=\"".$pics[1]."\" /><img src=\"".$pics[1]."\" cellpadding=\"0\" cellspacing=\"0\" width=\"200\" height=\"200\" /></a>\n";
echo "<a href=\"".$pics[2]."\" /><img src=\"".$pics[2]."\" cellpadding=\"0\" cellspacing=\"0\" width=\"200\" height=\"200\" /></a>\n";
echo "<a href=\"".$pics[3]."\" /><img src=\"".$pics[3]."\" cellpadding=\"0\" cellspacing=\"0\" width=\"200\" height=\"200\" /></a>\n";
echo "<a href=\"".$pics[4]."\" /><img src=\"".$pics[4]."\" cellpadding=\"0\" cellspacing=\"0\" width=\"200\" height=\"200\" /></a>\n";
echo "<a href=\"".$pics[5]."\" /><img src=\"".$pics[5]."\" cellpadding=\"0\" cellspacing=\"0\" width=\"200\" height=\"200\" /></a>\n";
echo "<a href=\"".$pics[6]."\" /><img src=\"".$pics[6]."\" cellpadding=\"0\" cellspacing=\"0\" width=\"200\" height=\"200\" /></a>\n";
echo "<a href=\"".$pics[7]."\" /><img src=\"".$pics[7]."\" cellpadding=\"0\" cellspacing=\"0\" width=\"200\" height=\"200\" /></a>\n";
?>
