html ファイルを添付ファイルとして送信するこのコードは、正しく機能しています。ただし、次のコード スニペットでは、画像への添付ファイルを変更すると送信されません。なぜですか?
<?php
$file_path = "file.html"; // server path where file is placed
$file_path_type = "text/html"; // File Type
$file_path_name = "newfilename.html"; // this file name will be used at reciever end
$from = "xyz@gmail.com"; // E-mail address of sender
$to = "abc@gmail.com"; // E-mail address of reciever
$subject = "Please check the Attachment."; // Subject of email
$message = "This is the message body.<br><br>Thank You!<br><a href='http://7tech.co.in'>7tech.co.in Team</a>";
$headers = "From: ".$from;
$file = fopen($file_path,'rb');
$data = fread($file,filesize($file_path));
fclose($file);
$rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$rand}x";
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
$message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message .= "\n\n";
$data = chunk_split(base64_encode($data));
$message .= "--{$mime_boundary}\n" .
"Content-Type: {$file_path_type};\n" .
" name=\"{$file_path_name}\"\n" .
"Content-Disposition: attachment;\n" .
" filename=\"{$file_path_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data .= "\n\n" .
"--{$mime_boundary}--\n";
if(@mail($to, $subject, $message, $headers)) {
echo "File send!";
} else {
echo 'Failed';
}
?>
添付ファイルを画像、つまり screenshot.png に変更すると、メッセージの送信に失敗します。
<?php
$file_path = "screenshot.png"; // server path where file is placed
$file_path_type = "image/png"; // File Type
$file_path_name = "screenshot.png"; // this file name will be used at reciever end
$from = "xyz@gmail.com"; // E-mail address of sender
$to = "abc@gmail.com"; // E-mail address of reciever
$subject = "Please check the Attachment."; // Subject of email
$message = "This is the message body.<br><br>Thank You!<br><a href='http://7tech.co.in'>7tech.co.in Team</a>";
$headers = "From: ".$from;
$file = fopen($file_path,'rb');
$data = fread($file,filesize($file_path));
fclose($file);
$rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$rand}x";
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
$message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message .= "\n\n";
$data = chunk_split(base64_encode($data));
$message .= "--{$mime_boundary}\n" .
"Content-Type: {$file_path_type};\n" .
" name=\"{$file_path_name}\"\n" .
"Content-Disposition: attachment;\n" .
" filename=\"{$file_path_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data .= "\n\n" .
"--{$mime_boundary}--\n";
if(@mail($to, $subject, $message, $headers)) {
echo "File send!";
} else {
echo 'Failed';
}
?>
エラーを指摘していただけますか。コンテンツ タイプも 1 ~ 2 か所変更しようとしましたが、うまくいきませんでした。
