Melampirkan dan Menghantar Berbilang Fail melalui E-mel dalam PHP
Tugas asal ialah mengubah suai kod yang hanya boleh menghantar satu lampiran fail untuk menghantar dua atau lebih banyak fail. Kod yang disemak ini menangani keperluan ini dengan membenarkan berbilang lampiran fail dihantar dalam e-mel:
<code class="php"><form action="#" method="POST" enctype="multipart/form-data"> <input type="file" name="csv_file[]" /><br> <input type="file" name="csv_file[]" /><br> <input type="file" name="csv_file[]" /><br> <input type="submit" name="upload" value="Upload" /><br> </form> <?php if($_POST) { // Create arrays for file information $ftype = $_FILES['csv_file']['type']; $fname = $_FILES['csv_file']['name']; // Define files to be attached $files = $fname; // Email fields $to = "recipient@example.com"; $from = "sender@example.com"; $subject = "Attachments"; $message = "Email with attached files"; $headers = "From: $from"; // Set MIME boundary $semi_rand = md5(time()); $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; // Create multipart header $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\""; // Build multipart message $message = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/plain; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n"; // Prepare each attachment foreach ($files as $key => $value) { $file = fopen($value, "rb"); $data = fread($file, filesize($value)); fclose($file); $data = chunk_split(base64_encode($data)); $message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$fname[$key]\"\n" . "Content-Disposition: attachment;\n" . " filename=\"$fname[$key]\"\n" . "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n"; $message .= "--{$mime_boundary}\n"; } // Send email $ok = @mail($to, $subject, $message, $headers); if ($ok) { echo "<p>Email sent to $to!</p>"; } else { echo "<p>Email could not be sent!</p>"; } } ?></code>
