I have the following shortcode which gets the images of that post (that will be in a folder named as the post's id ) and displays them echoing as many tag images as needed.
session_start();
$postID = $_SESSION['post_ID'];
$upload_dir = wp_upload_dir();
$path = $upload_dir['basedir'].'/'.'gallery/'.$postID;
if(file_exists($path)) {
$pathFile = $path.'/*';
$images = glob($pathFile);
if(!empty($images)) {
foreach($images as $image){
$alt = end(explode('/', $image));
echo '<img src="'.$image.'" alt="'.$alt.'" />';
}
} else echo 'No hay imágenes.';
} else echo 'No hay imágenes.';
?>
The problem is that the images aren't displayed, i get the followin error in the brower's console GET https://path-to-theme/wp-content/uploads/gallery/1658/wwg.jpg 404, per every image and i get this icon:
I have no idea why my images aren't displayed the images, the path is correct, the images are there, complitely no idea what I'm missing. It's not a permissions problem as i tried giving 755 permissions to the directories starting from /uploads/.. and so on including the images.
I fixed the problem. The issue wa sthat i wasn't uploading the images as wp wants me to, therefore the images, even they were in the folder, couldn't be displayed. So I had to change the way i uploaded them, by using wp functions and specifying the mime_type etc so wp could store their metadata in it's db in order to be able to acknowledge them and display them in a future.
