Question

我使用的是PHP 5.6。尝试使用脚本时，我收到错误。该脚本用于发送电子邮件，这里是它的副本。我需要帮助修复它。谢谢。错误也在下面：

注意：未定义的偏移量：第36行的C：\ Apache \ htdocs \ ~s spamsite \ email.php中的1

这是脚本：

＆＃13;

<?php 

if( isset($_POST['submit'])) 
{
//define the receiver of the email 
    $to = $_POST["to"]; 
//define from whom the email is from ie Name & E-Mail.
    $name=$_POST["name"];
    $from = $_POST["from"]; 
//define who will be copied.
    $cc = $_POST["cc"];
//define who will be blind copied.
    $bcc = $_POST["bcc"];
//define the subject of the email 
    $subject = $_POST["subject"]; 
//define the message of the email 
    $message=$_POST["message"]; 
//so we use the MD5 algorithm to generate a random hash 
    $random_hash = md5(date('r', time())); 
//define the headers we want passed. Note that they are separated with \r\n 
    $headers  = "From: " . $name . "<" . $from . ">" . "\nCc: " . $cc . "\nBcc: " . $bcc;
// boundary 
    $semi_rand = md5(time()); 
    $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 

// headers for attachment  
    $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\""; 

// multipart boundary 
    $message = "--{$mime_boundary}\n" . "Content-Type: text/html; charset=\"UTF-8\"\n" .
    "Content-Transfer-Encoding: 7bit\n\n" . "<p>" . $message . "</p>" . "\n\n"; 
 
// Preparing Attachment.
    for($i=0;$i<(count($_FILES["attachment"]["name"])+1);$i++)
    {
        if($_FILES["attachment"]["name"][$i] != "")
        {
            $filename = $_FILES["attachment"]["name"][$i];
            $filetype = $_FILES["attachment"]["type"][$i];
            $content  = chunk_split(base64_encode(file_get_contents($_FILES["attachment"]["tmp_name"][$i]))); 
            $message .= "--{$mime_boundary}\n";
            $message .= "Content-Type: " . $filetype . "; name=\"".$filename."\"\n"; 
            $message .= "Content-Description: " .$filename . "\n";
            $message .= "Content-Disposition: attachment;\n" . " filename=\"".$filename."\";\n";
            $message .= "Content-Transfer-Encoding: base64\n\n" . $content."\n\n";
        }
            
    }
    $message .= "--{$mime_boundary}--\r\n";
    
//send email
    $mail = @mail($to, $subject, $message, $headers, "-f$from"); 
    
//if the message is sent successfully print "Mail sent". Otherwise print "Mail failed" 
    echo $mail? "Your Mail Has Been Sent Successfully" : "Oops..Something Went Wrong.. Your Mail Has Not Been Sent"; 
}

Answer 1

如果您不确定数组是否包含某些键，则应使用

if(isset($array['key'])) {
    //Do something
}

您似乎应该更改此行

 for($i=0;$i<(count($_FILES["attachment"]["name"])+1);$i++)

到

if(isset($_FILES["attachment"]) && isset($_FILES["attachment"]["name"]))
    for($i=0;$i<(count($_FILES["attachment"]["name"])+1);$i++)

Answer 2

你的for循环看起来有错误：

试试这个：

for($i = 0; $i < count($_FILES["attachment"]["name"]); $i++)

而不是：

for($i=0;$i<(count($_FILES["attachment"]["name"])+1);$i++)

因为如果您连接了3个文件，那么将会：

$_FILES["attachment"]["name"][0]
$_FILES["attachment"]["name"][1]
$_FILES["attachment"]["name"][2]

你的count($_FILES["attachment"]["name"])将返回3.而你只想升到2。
