php4 - Sort (date & size) listing of dir.

Good day to you all,
I'm building a little image directory viewer and I want it to list the images by date they were uploaded and within that by landscape or portrait.

I would need newest on top.

Here is the code I have so far :

PHP Code:


		
			
<?php



$val= $_GET['folder'];

$val.="/";









$imgdir = $val; // the directory, where your images are stored

$allowed_types = array('png','jpg','jpeg','gif'); // list of filetypes you want to show



$dimg = opendir($imgdir);

while($imgfile = readdir($dimg))

{

 if(in_array(strtolower(substr($imgfile,-3)),$allowed_types))

 {

  $a_img[] = $imgfile;

  sort($a_img);

  reset ($a_img);

 } 

}



$totimg = count($a_img); // total image number

 

for($x=0; $x < $totimg; $x++)

{

 $size = getimagesize($imgdir.'/'.$a_img[$x]);





 

echo "<tr><td>";

if ($size[0] > "199"){



 echo '<img src="'.$imgdir.'/'.$a_img[$x].'" width="50" border="0">';

}

echo "</td</tr>";

 

 

echo "<tr><td>";

if ($size[1] > "199"){



 echo '<img src="'.$imgdir.'/'.$a_img[$x].'" width="50" border="0">';

}

echo "</td></tr>";

}

?>

Can someone guide me with this please ?

Thanks !
Have a nice day !

First of all, you have many unnecessary calls to sort(). I would rewrite your directory reading loop:

PHP Code:


		
			
 $dimg = opendir($imgdir);

while($imgfile = readdir($dimg))

{

    if(in_array(strtolower(substr($imgfile,-3)),$allowed_types))

    {

        $a_img[] = $imgfile;

        $fmodtime[] = filemtime($imgdir($imgfile));

    } 

}



array_multisort($fmodtime, SORT_DESC, $a_img); // sort both arrays so that the file that was modified last is first.

reset($fmodtime);

reset($a_img);

That should work. I didn't test it, though. If you need to show the file modification time in a human readable format you can use date() to do that.

I can't make it to work, I had implemented it but here what I have done and what it do :

PHP Code:


		
			
 $val0 = $_GET['folder'];

$val0 = $val1;

$val0.="/";





 $dimg = opendir($imgdir);

while($imgfile = readdir($dimg))

{

    if(in_array(strtolower(substr($imgfile,-3)),$allowed_types))

    {

        $a_img[] = $imgfile;

        $fmodtime[] = filemtime($imgdir($imgfile));

    } 

}



array_multisort($fmodtime, SORT_DESC, $a_img); // sort both arrays so that the file that was modified last is first.

reset($fmodtime);

reset($a_img);

it give me : Warning: readdir(): supplied argument is not a valid Directory

Can you help me again?

That's because you're now calling your directory name variable $val0 instead of $imgdir like you previously did.

Now it give me this :
Warning: array_multisort(): Argument #1 is expected to be an array or a sort flag in

PHP Code:


		
			
 $imgdir = $_GET['folder'];

$imgdir.="/";

  $allowed_types = array(".png", ".jpg", ".jpeg", ".gif");





 $dimg = opendir($imgdir);

while($imgfile = readdir($dimg))

{

    if(in_array(strtolower(substr($imgfile,-3)),$allowed_types))

    {

        $a_img[] = $imgfile;

        $fmodtime[] = filemtime($imgdir($imgfile));

    } 

}



array_multisort($fmodtime, SORT_DESC, $a_img); // sort both arrays so that the file that was modified last is first.

reset($fmodtime);

reset($a_img);  

 echo '<img src="'.$imgdir.'/'.$a_img[$x].'" width="50" border="0">';

D'oh... this mistake was so stupid I'm ashamed. The $fmodtime line should be

PHP Code:


		
			
 $fmodtime[] = filemtime($imgdir.$imgfile);
