Warning: file_get_contents (): Filename cannot be empty in /srv/disk18/3303837/www/pommecannelle.lu/encomendas/php/sendmail.php on line 41
The value returned by $row['imagem'] is empty. Check your database that the column exists and isn't empty for any rows. The first row with a null or empty imagem is causing this error.
You should check (a) if that row has a filename and (b) that the file was read successfully:
ob_start();
$attachment = false;
if (!empty($row['imagem']) {
$fileContents = file_get_contents($row['imagem']);
if ($fileContents !== FALSE) {
$attachment = chunk_split(base64_encode($fileContents));
}
}
if ($attachment) {
// Now send your email
...
}
I also noticed you never did anything with $attachment.
Depending on if this is a hobby vs. large-scale project, you should also check if the column exists with array_key_exists() , and/or work on error handling as well.
