我最终创建了一个联系表单的代码，但是有一件事我想要，但是最大大小为5 MB，如果尝试了函数if($file_size > 5000000){$fileErr = "max allowed size is 5 mb";} else{$check6 = 1;}但是它不起作用且代码不能正常工作但是，如果我删除此功能，其他一切都会很好，所以任何帮助，当我解决这个问题时，我会在这里添加代码，这样每个人都可以从中获益....这里是下面的代码

您的情况正确，您的代码也正常运行。请重新检查。

答案 1 :(得分：1)

当allowedExtensions为真时，您设置了$ check5 = 1。在它旁边，您检查file_size。当您的file_size＆gt; 5MB，check5未重置或更改。因此，如果您的附件是正确的＆amp; file_size＆gt; 5mb系统将尝试发送带有附件（您不想要的）的电子邮件为check5==1。所以要停止它，你需要在file_size＆gt;时设置check5=0。 5MB。

请更新您的代码，如：

if($file_size > 5000000){
       $fileErr .= "Max allowed size is 5 MB";
} else {
        $check6 = 1;
        array_push($files,$file);
 }

希望这很清楚

试试PHPMailer，我使用它就没有问题了。

<?php
/**
 * PHPMailer simple file upload and send example
 */
$msg = '';
if (array_key_exists('userfile', $_FILES)) {
    // First handle the upload
    // Don't trust provided filename - same goes for MIME types
    // See http://php.net/manual/en/features.file-upload.php#114004 for more thorough upload validation
    $uploadfile = tempnam(sys_get_temp_dir(), sha1($_FILES['userfile']['name']));
    if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
        // Upload handled successfully
        // Now create a message
        // This should be somewhere in your include_path
        require '../PHPMailerAutoload.php';
        $mail = new PHPMailer;
        $mail->setFrom('from@example.com', 'First Last');
        $mail->addAddress('whoto@example.com', 'John Doe');
        $mail->Subject = 'PHPMailer file sender';
        $mail->Body = 'My message body';
        // Attach the uploaded file
        $mail->addAttachment($uploadfile, 'My uploaded file');
        if (!$mail->send()) {
            $msg .= "Mailer Error: " . $mail->ErrorInfo;
        } else {
            $msg .= "Message sent!";
        }
    } else {
        $msg .= 'Failed to move file to ' . $uploadfile;
    }
}
?>
