我有一个前端表单，允许用户上传简历，然后将简历作为附件与表单的其余部分一起发送。为此，我使用了wp_handle_upload() 像这样：

if ($_FILES) {

if ( ! function_exists( \'wp_handle_upload\' ) ) require_once( ABSPATH . \'wp-admin/includes/file.php\' );
$uploadedfile = $_FILES[\'file\'];
$upload_overrides = array( \'test_form\' => false );
$movefile = wp_handle_upload( $uploadedfile, $upload_overrides );
    if ( $movefile ) {
        echo "File is valid, and was successfully uploaded.\\n";
        var_dump( $movefile);
    } else {
        echo "Possible file upload attack!\\n";
    } 
}

检查错误后，表单将与wp\\U邮件一起发送：($receiver_email, $subject, $body, $headers 都很好，可以看到here

$attachments = $uploadedfile;

if (wp_mail($receiver_email, $subject, $body, $headers, $attachments)) {
        
    $jobs_email_sent = true;

} else {
    $jobs_email_sent_error = true;
}

然而，我从var_dump($movefile) 当我提交表格时。

File is valid, and was successfully uploaded.
array(1) {
 ["error"]=>
 string(212) "File is empty. Please upload something more substantial. This error could also be caused by uploads being disabled in your php.ini or by post_max_size being defined as smaller than upload_max_filesize in php.ini."
}

而且邮件自然没有附件。我检查了php。ini和file\\u uploads确实已打开，upload\\u max\\u filesize为128M。我尝试添加一个pdf和一个jpg文件，这两个文件都很小。

如果你能了解我在这里做错了什么，我将不胜感激。

更新只需阅读wp_mail() 必须完全指定文件路径，如中所示$attachments = array(WP_CONTENT_DIR . \'/uploads/file_to_attach.zip\');应该在wp_handle_upload(); 作为文件。

当我var\\u dump（$\\u文件）时，我得到：

array(1) {
  ["upload_file"]=>
  array(5) {
    ["name"]=>
    string(5) "3.jpg"
    ["type"]=>
    string(10) "image/jpeg"
    ["tmp_name"]=>
    string(14) "/tmp/php3aeSzD"
    ["error"]=>
    int(0)
    ["size"]=>
    int(53262)
  }
 }

我的文件名为3。jpg。
