I am attempting to upload company logo images to my Media Library - but I am noticing some problems...
Namely, some of those images seem to come in at 0Kb created.
Source image URLs are all like ?format=png
I wish to store them in /home/mysite/public_html/wp-content/uploads/org_logos/{companyname}.png
... wherein companyname is the slug of the corresponding company term for taxonomy Organisation.
Here is my code...
// Remote logo URL
$image_url = $json_object->logo.'?format=png';
// Generate a file path and name
$upload_dir = wp_upload_dir();
$image_data = file_get_contents( $image_url );
$filename = $company_term->slug.'.png';
if ( wp_mkdir_p( $upload_dir['path'] ) ) {
$file = $upload_dir['path'] . '/org_logos/' . $filename;
}
else {
$file = $upload_dir['basedir'] . '/org_logos/' . $filename;
}
// Copy the file
file_put_contents( $file, $image_data );
// Add to Media Library
$wp_filetype = wp_check_filetype( $filename, null ); // eg. image/png
$attachment = array(
'post_mime_type' => $wp_filetype['type'],
'post_title' => sanitize_file_name( $filename ),
'post_content' => '',
'post_status' => 'inherit'
);
$attach_id = wp_insert_attachment( $attachment, $file );
require_once( ABSPATH . 'wp-admin/includes/image.php' );
$attach_data = wp_generate_attachment_metadata( $attach_id, $file );
wp_update_attachment_metadata( $attach_id, $attach_data );
This is successfully adding something to both the server and the Media Library every time. But, whilst sometimes that is an actual image, sometimes it is 0Kb and/or a blank thumbnail in the Media Library.
I had thought there was an issue around using slug where it contains dashes as a filename because the resulting image file for source ?format=png (/home/mysite/public_html/wp-content/uploads/org_logos/starcom-mediavest-group.png) is always blank.
But, actually, the problem goes for more than just filenames which take slugs bearing dashes, because another problematic example is a no-dash source ?format=png
wherein file /home/mysite/public_html/wp-content/uploads/org_logos/cadreon.png is also 0Kb.
Image types are confirmed as image/png.
Is the problem my file_put_contents, my WordPress code or something else?
It's weird, because it works sometimes.
