How to sort files in thumbnail script

[meek]

Hi there.

This script shows clickable thumbnails of images in a folder. However, they seem to be shown quite randomly and not in any particular order. Could someone help me change the script to sort the images in alphabetical order when they are displayed?

<?php

function listFiler($folder) {

 if($bib = @opendir($folder)) {
   while (false !== ($fil = readdir($bib))) {
     if($fil != "." && $fil != ".." && !ereg("^\..+", $fil)) {
         list($w, $h, $x, $x) = getimagesize( "$folder/$fil" );
          $fil_liste[] = "<a href=\"javascript:popit('$folder/$fil', $w, $h)\"><img src=\"$folder/$fil\" width=\"100px\" height=\"100px\" border=\"0\" alt=\"$fil\" title=\"$fil\" style=\"border:1px solid #333;\"></a>";
     }
   }
   closedir($bib);

   if(is_array($fil_liste)) {
     $liste = join(" ", $fil_liste);
   } else {
     $liste = "No files...";
   }
   return ""
   . "$liste";
 } else {
   die("Could not open: " . $folder);
 }
}

echo listFiler("photos"); //Choose folder.

?>

Thanks in advance.

I did the same thing before, one way I do it is read file names into an array, then sort the array, then loop the array of ordered file names, assign the thumbnails. here's the logic of sort multi-dim array:

for ($counter_1 = 0; $counter_1 < sizeof($arr_test); $counter_1++){
for ($counter_2 =$counter_1 + 1 ; $counter_2 < sizeof($arr_test); $counter_2++){
if ($arr_test[$counter_1]["filename"] > $arr_test[$counter_2]["filename"]){
$temp_arr = $arr_test[$counter_1];
$arr_test[$counter_1] = $arr_test[$counter_2];
$arr_test[$counter_2] = $temp_arr;
}
}
}

Thanks, looks interesting! I'm new to php, so could you add the array to the existing script for me, please? I have no idea how to implement it.

not tested, you need debug yourself

<?PHP

function listFiler($folder) {

if($bib = @opendir($folder)) { 

	/**
	 * Read the file names, imagesize into array
	 */
	while (false !== ($fil = readdir($bib))) { 
		if($fil != "." && $fil != ".." && !ereg("^..+", $fil)) { 
			list($w, $h, $x, $x) = getimagesize( $folder.'/'.$fil ); 
			$arr_files[] = array('filename'=>$fil, 'w'=>$w, 'h'=>$h, 'x'=>$x, 'x'=>$x);
		}
	}

	/**
	 * sort the array by filename
	 */
	for ($counter_1 = 0; $counter_1 < sizeof($arr_files); $counter_1++){
		for ($counter_2 =$counter_1 + 1 ; $counter_2 < sizeof($arr_files); $counter_2++){
			if ($arr_files[$counter_1]['filename'] > $arr_files[$counter_2]['filename']){
				$temp_arr = $arr_files[$counter_1];	
				$arr_files[$counter_1] = $arr_files[$counter_2];
				$arr_files[$counter_2] = $temp_arr;
			}
		}
	}

	/**
	 * set html
	 */
	for ($i = 0; $i < sizeof($arr_files); $i++){
		$fil_liste[] = "<a href=\"java script:popit('{$folder}/{$fil}', {$w}, {$h})\"><img src=\"$folder/$fil\" width=\"100px\" height=\"100px\" border=\"0\" alt=\"$fil\" title=\"$fil\" style=\"border:1px solid #333;\"></a>"; 
	}
} 

}
closedir($bib);

if(is_array($fil_liste)) {
$liste = join(" ", $fil_liste);
} else {
$liste = "No files...";
}
return ""
. "$liste";
} else {
die("Could not open: " . $folder);
}
}

echo listFiler("photos"); //Choose folder.

?>

Thanks. I get a parse error in this line: } else { - any idea why?

[dewen]

sorry, try this

<?PHP
function listFiler($folder) {

if($bib = @opendir($folder)) { 

	/**
	 * Read the file names, imagesize into array
	 */
	while (false !== ($fil = readdir($bib))) { 
		if($fil != "." && $fil != ".." && !ereg("^..+", $fil)) { 
			list($w, $h, $x, $x) = getimagesize( $folder.'/'.$fil ); 
			$arr_files[] = array('filename'=>$fil, 'w'=>$w, 'h'=>$h, 'x'=>$x, 'x'=>$x);
		}
	}

	/**
	 * sort the array by filename
	 */
	for ($counter_1 = 0; $counter_1 < sizeof($arr_files); $counter_1++){
		for ($counter_2 =$counter_1 + 1 ; $counter_2 < sizeof($arr_files); $counter_2++){
			if ($arr_files[$counter_1]['filename'] > $arr_files[$counter_2]['filename']){
				$temp_arr = $arr_files[$counter_1];	
				$arr_files[$counter_1] = $arr_files[$counter_2];
				$arr_files[$counter_2] = $temp_arr;
			}
		}
	}

	/**
	 * set html
	 */
	for ($i = 0; $i < sizeof($arr_files); $i++){
		$fil_liste[] = "<a href=\"java script:popit('{$folder}/{$fil}', {$w}, {$h})\"><img src=\"$folder/$fil\" width=\"100px\" height=\"100px\" border=\"0\" alt=\"$fil\" title=\"$fil\" style=\"border:1px solid #333;\"></a>"; 
	}

	closedir($bib); 

	if(is_array($fil_liste)) { 
		$liste = join(" ", $fil_liste); 
	} else { 
		$liste = "No files..."; 
	} 
	return "" . "$liste"; 
} else { 
	die("Could not open: " . $folder); 
} 

}

echo listFiler("photos"); //Choose folder.

?>

Thanks. No parse error now but I get the message: No files...

[dewen]

does you original code works? try change

if($fil != "." && $fil != ".." && !ereg("^..+", $fil)) {

to

if($fil != "." && $fil != "..") {

worked on my system

[meek]

Ah, this one works:

    <?php

function listFiler($folder) {

 if($bib = @opendir($folder)) {
$filnavne = array();
while (false !== ($fil = readdir($bib))) {  // Get filenames
  if($fil != "." && $fil != ".." && !ereg("^\..+", $fil)) {
    $filnavne[] = $fil;
  }
}
sort( $filnavne );        //  ordering array according to filename
foreach( $filnavne as $fil ) {            // Writing array
    list($w, $h, $x, $x) = getimagesize( "$bibliotek/$fil" );
    $fil_liste[] = "<a href=\"javascript:popit('$bibliotek/$fil', $w, $h)\"><img src=\"$bibliotek/$fil\" width=\"100px\" height=\"100px\" border=\"0\" alt=\"$fil\" title=\"$fil\" style=\"border:1px solid #333;\"></a>";
}
   closedir($bib);

   if(is_array($fil_liste)) {
     $liste = join(" ", $fil_liste);
   } else {
     $liste = "No files...";
   }
   return ""
   . "$liste";
 } else {
   die("Could not open: " . $folder);
 }
}

echo listFiler("photos"); //Choose folder.

?>

But thanks a lot for your help, dewen. :-)
