I've searched around and I found some similar questions asked, but none that really help me (as my PHP abilities aren't quite enough to figure it out). I'm thinking that my question will be simple enough to answer, as the similar questions I found were solved with one or two lines of code. So, here goes!
I have a bit of code that searches the contents of a given directory, and provides the files in an array. This specific directory only has .JPG image files named like this:
Shot01.jpg Shot01_tn.jpg
so on and so forth. My array gives me the file names in a way where I can use the results directly in an tag to be displayed on a site I'm building. However, I'm having a little trouble as I want to limit my array to not return items if they contain "_tn", so I can use the thumbnail that links to the full size image. I had thought about just not having thumbnails and resizing the images to make the PHP easier for me to do, but that feels like giving up to me. So, does anyone know how I can do this? Here's the code that I have currently:
$path = 'featured/';
$newest = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path, RecursiveDirectoryIterator::SKIP_DOTS));
$array = iterator_to_array($newest);
foreach($array as $fileObject):
$filelist = str_replace("_tn", "", $fileObject->getPathname());
echo $filelist . "<br>";
endforeach;
I attempted to use a str_replace(), but I now realize that I was completely wrong. This returns my array like this:
Array
(
[0] => featured/Shot01.jpg
[1] => featured/Shot01.jpg
[2] => featured/Shot02.jpg
[3] => featured/Shot02.jpg
[4] => featured/Shot03.jpg
[5] => featured/Shot03.jpg
)
I only have 3 images (with thumbnails) currently, but I will have more, so I'm also going to want to limit the results from the array to be a random 3 results. But, if that's too much to ask, I can figure that part out on my own I believe.
So there's no confusion, I want to completely remove the items from the array if they contain "_tn", so my array would look something like this:
Array
(
[0] => featured/Shot01.jpg
[2] => featured/Shot02.jpg
[4] => featured/Shot03.jpg
)
Thanks to anyone who can help!
<?php
function filtertn($var)
{
return(!strpos($var,'_tn'));
}
$array = Array(
[0] => featured/Shot01.jpg
[1] => featured/Shot01_tn.jpg
[2] => featured/Shot02.jpg
[3] => featured/Shot02_tn.jpg
[4] => featured/Shot03.jpg
[5] => featured/Shot03_tn.jpg
);
$filesarray=array_filter($array, "filtertn");
print_r($filesarray);
?>
