For you experts out there.. picture finding

webchef

Hello, and thanks in advance for any help.

Lets say i ran a query to get the auto_id of an article.

each article may or may not contain 1 or more pictures of either jpeg, or gif type.

so if the auto_id of an article is 25. then pictures for the article could be as follows:

25_01.jpg OR 25_01.gif

25_01.jpg, 25_02.jpg, 25_03.gif

or Etc. Etc.

basically what i need done is to find all the pictures, whether gif or jpg, that corrospond to the article. and put the names in an array:

example:
// all pictues in the following array corrospond to article 25
$pictures = array(1 => "25_01.jpg", "25_02.gif", "25_03.jpg");

i've been running in circles for a couple of days now.. what is the best way of doing this?

Thanks again.

Mike

Are the picture filenames in a table or do you want to locate them in directory?

webchef

they are all in a folder.. if it was in a database, i would have done it already.. but this is where the problem comes in...

i was thinkinng of something along these lines:

$jpg_ext = ".jpg";
$gif_ext = ".gif";
$pic_count = 1;
$pictures = array ("no_pic.gif");
while (file_exists($auto_id ._. $pic_count . $jpg_ext)) {
	array_push($pictures, $auto_id ._. $pic_count . $jpeg_ext);
	$pic_count++;
}
while (file_exists($auto_id ._. $pic_count . $gif_ext)) {
	array_push($pictures, $auto_id ._. $pic_count . $gif_ext);
	$pic_count++;
}

webchef

well it seems no one in this board was able to help me...

But thanks for all who tried anyway... in case anyone is interested.. here is the solution:

function getFiles($dirname, $key) {  

	 $handle=opendir($dirname); 
	 while ($file = readdir($handle)) 
	 { 
			if($file=='.'||$file=='..') 
				continue; 
			else 
			{ 
				if (eregi($key, $file)) {    $result_array[]=$file; } 
			} 
	 } 
	 closedir($handle); 
	 return $result_array; 
 } 
 $a = $auto_id . "_";
 $pictures = getFiles("images", $a); 
 echo "$pictures[0] <br> $pictures[1] <br> $pictures[2] $pictures[3] <br>";

Thanks again...

see ya
