I am submitting an image to the db like this:
if (isset($_POST['uploadImgCustom'])) {
$myNewImg = get_post_meta($id, 'usp-file-single', true);
}
$attachments = get_posts(array(
'post_type' => 'attachment',
'numberposts' => -1,
'post_status' =>'any',
'post_parent' => $post->ID
));
if ($attachments) {
foreach ( $attachments as $attachment ) {
$myNewImg = wp_get_attachment_url( $attachment->ID );
update_post_meta( $id, 'usp-file-single', $myNewImg);
}
?>
<img src="<?php echo $myNewImg; ?>" class="img-responsive">
<?php }
And then I do:
if($_SERVER['REQUEST_METHOD']=="POST") {
if ('AGGIORNA ALLEGATO' === ($_POST['uploadImgCustom'])) {
if ($_FILES['postImage']) {
$attachments = get_attached_media( '', $id );
foreach ($attachments as $attachment) {
wp_delete_attachment( $attachment->ID, 'true' );
}
foreach ($_FILES as $file => $array) {
if ($_FILES[$file]['error'] !== UPLOAD_ERR_OK) {
//Add your error action
} else {
$attach_id = media_handle_upload( $file, $id );
}
}
}
}
}
The new file is uploaded correctly and the page refreshes itself after upload completed. Yet I am seeing the old image on the page, however if I refresh the page, I see the new file. It is like keeping the cache and not reading the new data at first.
The following it is the current post ID which I grab at the beginning of the code right after I start the loop.
$id = get_the_ID();
The form html is the following:
<div class="row">
<div class="col-xs-12">
<h3>CARICA UNA NUOVA IMMAGINE O VIDEO</h3>
<form method="POST" action="" enctype="multipart/form-data">
<div class="form-group">
<input type="file" name="postImage" multiple="multiple" class="form-control">
</div>
<input id="uploadImg" name="uploadImgCustom" type="submit" value="AGGIORNA ALLEGATO" class="btn secondary-btn primary-bg">
</form>
</div>
</div>
