Gallery Images Sorting

[jagmeet]

Hi Frnds

I m Using Photo Album ..... when i connect to Server through Php FTP script connection .... in image sorting m getting 1 problem.

Example:
1.jpg (Main Images)
2.jpg
3.jpg
th_1.jpg (Thumbnail Main Images)
th_2.jpg
th_3.jpg

Prob: my script also Sorting "Thumbnail Pics" but i want to sort only "Main Image"

How can i set Files Sorting Filter .... plzz help/give me php Filter Function who filter and Remove "th_1.jpg, th_2.jpg, th_3.jpg" from sorting and show only "1.jpg, 2.jpg, 3.jpg"

$dir = "h t t p:/ /w w w.domain.c o m/anyalbum";
$filearray = array();
if ($fil = opendir($dir))
{
while (($file = readdir($fil)) !== false)
   {
//if ($file != "." && $file != "..")
if (strpos($file, '.jpg',1)||strpos($file, '.gif',1) )
      {
$filearray[] = $file;
      }
   }

Change this line:

if (strpos($file, '.jpg',1)||strpos($file, '.gif',1) ) 

To this:

if ((strpos($file, '.jpg', 1) !== false || strpos($file, '.gif', 1) !== false) && strpos($file, 'th_') != 0)

Sir ...
thx for reply ...... m going to try dis code

Dan, using your suggestion, $filearray would be just an empty array?

Should be:

if ((stripos($file, ".jpg", 1) !== false || stripos($file, ".gif", 1) !== false) && (stripos($file, "th_") == 0)) {
// not !=, but ==
// also swtiched to stripos() in case extensions are JPG and what not. 

Also something to think about, if the file extension happens to be .JPEG, the above if statement would not catch it.

if (preg_match("/\.(jpg|jpeg|gif?)$/i", $file) && !preg_match("/^th_/i", $file)) { 

[Dan Grossman]

Is it not equivalent to what you wrote? I just added a check that "th_" does not appear at the 0th position of the file name.

[notepad_coder]

I ran it and i get an empty array using !=, switching to == returned the file data.

[Dan Grossman]

It should be !== instead of !=, like the other conditions, my typo

Need to differentiate between false and the 0th position, which both evaluate to false

Using the string functions should be slightly faster than regex for this if it matters

[notepad_coder]

True, using strpos() is about 90% faster, but using regex lets you define more extension types without a huge if statement :/
