我有一个插件，我正在使用发送电子邮件的PHP表单。表单中的所有内容都是发送我需要发送的值，但是有一个文件附件区域，用户可以在其中附加多个文件。
html表单（通过插件中的echo＆gt;）
function html_form_code() {

我已经拥有＆＃34;文件[]＆＃34;作为该字段的名称，因为我假设我需要将每个文件添加到数组中，然后以可以解释的方式将其吐出到电子邮件中。我已经尝试了很多东西，但不能使这个工作完成。
如何在wordpress中将多个文件附加到php表单以便通过电子邮件发送？
答案 0 :(得分：0)
你错过了最后一个参数$attachments，它可以是一个数组。 您指定要使用 file[]但我在输入名称中看不到它。
$attachments = array( WP_CONTENT_DIR . '/uploads/file_to_attach.zip' );
wp_mail( $to, $subject, $message, $headers, $attachments );
您可以使用函数move_uploaded_file()复制服务器上的文件，并在邮件发送后立即unlink()。
答案 1 :(得分：0)
所以我最终解决了它。感谢@Benoti带领我朝着正确的方向前进。这是在上传过程中添加了安全性的最终产品。
//file upload function
$total = count($_FILES['upload']['name']);
$attachments = "";
$attachmentString = "";
$attachmentSet = false;
//variables for validation
$maxsize = 2097152; //just over 2mb
$whitelist = array(
'image/jpeg',
'image/jpg',
'image/gif',
'image/png'
);
if(file_exists($_FILES['upload']['tmp_name'][0]) || is_uploaded_file($_FILES['upload']['tmp_name'][0])) {
//hey look the attachment is set!
$attachmentSet = True;
// Loop through each file
for($i=0; $i<$total; $i++) {
//Get the temp file path
$tmpFilePath = $_FILES['upload']['tmp_name'][$i];
//Make sure we have a filepath
if ($tmpFilePath != ""){
$uploaddir = 'var/www/uploadsfolderpath/'#changed for security
wp_mkdir_p( $uploaddir );
//rename file
$orig_name = $_FILES["upload"]["name"][$i];
$temp = explode(".", $orig_name);
//give name with original name added by user plus hash random value
$newfilename = array_values($temp)[0] . md5(array_values($temp)[0]) . '.' . end($temp);
//variables per each iteration
//Setup our new file path
$newFilePath = $uploaddir . $newfilename; //renamed file added to new file path
$file_type = $_FILES['upload']['type'][$i]; //returns the mimetype
$imageinfo = getimagesize($_FILES['upload']['tmp_name'][$i]);//returns size of image

$max_file_size_in_bytes = 2140907; // 2MB in bytes
if(count($errors) === 0)
{
#restrict the limit

}
}
else

}

if($imageinfo['mime'] != 'image/gif' && $imageinfo['mime'] != 'image/png' && $imageinfo['mime'] != 'image/jpeg' && isset($imageinfo))
{
$errors[] = 'Invalid file type. Only JPG, GIF and PNG types are accepted.';
}
//file type verficatio
if(!in_array($file_type, $whitelist) && !empty($_FILES["upload"]["type"])) {

}
//all conditions passed, upload files!
if(count($errors) === 0) {
//Upload the file into the temp dir
if(move_uploaded_file($tmpFilePath, $newFilePath)) {
chmod($newFilePath, 0644);
$attachments[$i] = $newFilePath;
//make string for sending to email
$attachmentString[$i] = $newFilePath;
$headers .= "Content-Disposition: attachment; filename = \"" . $attachmentString[$i] . "\"\n\n";
}
}
}
}//end of loop
}
// If email has been process for sending, display a success message
if(count($errors) === 0) {
if ( wp_mail( $to, $subject, $message, $headers, $attachments ) ) {
echo '<div class="success"><p>Success! Thanks for contacting us, expect a response soon.</p></div>';
if ($attachmentSet) {
//clean up your temp files after sending
foreach($attachments as $att) {
@unlink($att);
};
}
}
}
else {
echo '<div class="error">';
foreach($errors as $error) {
echo '<p>' .$error . '</p>';
}
echo '</div>';
}
}
}
这是文件上传部分（仍然是相同的邮件功能）。

建议欢迎，因为这是我第一次用php构建这样的东西：）
