This function grabs all the jpegs from folders which match the page name and prints a background image. On the homepage it searches all the sub directories and chooses one at random. What i would like is to exclude (on the homepage only) certain files which match an array of names...can anyone help?
$isHome = $this->level() == 0;
$path = 'public/images/bg/';
if (!$isHome) $path .= $this->slug;
$homepagefile = URL_PUBLIC.'public/images/bg/'.$this->slug.'/main.jpg';
$bgimagearray = array();
$iterator = new DirectoryIterator($path);
foreach ($iterator as $fileinfo) {
if ($fileinfo->isFile() && !preg_match('\.jpg$/', $fileinfo->getFilename()) && !$isHome) {
$bgimagearray[] = "'" . $fileinfo->getFilename() . "'";
} else if ($fileinfo->isDir() && $isHome) {
$iterator2 = new DirectoryIterator($path . $fileinfo->getFilename());
foreach ($iterator2 as $fileinfo2) {
if ($fileinfo2->isFile() && !preg_match('\.jpg$/', $fileinfo2->getFilename())) {
$bgimagearray[] = "'" . $fileinfo->getFilename() . '/' . $fileinfo2->getFilename() . "'";
}
}
}
}
$bgimage = array_rand($bgimagearray);
In simple terms, you just need another condition in the if
statement when filtering which items go into the bgimagearray
for the homepage.
if ($fileinfo2->isFile()
&& !preg_match('\.jpg$/', $fileinfo2->getFilename())
&& ! in_array($fileinfo2->getFilename, $my_blacklist_array) // added
) {
Aside: your code is a little messy and your task could likely be solved with prettier code structure; however, that would be a rewrite of your existing code rather than answering the question posed.
