Question

I’m trying to delete photos from a folder, which is called, “photos”, that are NOT currently in my database. (These are all photos that have stacked up as I’ve been building the website and testing it and such, so now it’s time to take the site live and I don’t want all this waste in it)

I have three tables with photo information in them, and a number of columns throughout. Below is a mockup query of about what I THINK it should look like.

SELECT left_image, right_image, photo1, photo2, photo3, photo4, home_photo 
FROM about_photos, facilities, home

left_image and right_image go with about_photos.
photo1, photo2, photo3 and photo4 go with facilities.
home_photo goes with home.

Also, I need to use a wildcard for the end of the photo, because the files have thumbnails, so for instance the original photo would be called, abcimage.jpg but there would be abcimage.jpg, abcimage_medium.jpg, abcimage_thumb.jpg also in the database I only store, photos/abcimage and add the rest of the filename depending on where it goes.

Answer 1

$directory = "../path/to/photos_directory/";

//get all image files with a .jpg extension.
$images = glob($directory . "*.jpg");

foreach($images as $image)
{
    $name = explode('_',$image);
    $name = 'photos/' . $name[0];
    $sql = mysql_query("SELECT id FROM table WHERE photo1='$name' OR photo2='$name'");
    if(mysql_num_rows($sql) == 0)
        unlink($directory . $image);
}
