我不是wordpress的专家，我正在尝试创建一个前端表单，通过ajax将信息发送到我的php函数。我需要关于上传图片和文件作为帖子附件的帮助。

我的jQuery/Ajax正在将所有内容正确地发送到我的php文件中。我唯一不明白的是，为什么上传图像和文件的功能不同？

我的html输入相对命名为：

• name="moreimages"
• name="morefiles"

我将此php代码用于图像和文件

if ($_FILES)
    {
        // Get the upload images
        $images = $_FILES[\'moreimages\'];
        foreach ($images[\'name\'] as $key => $value)
        {
            if ($images[\'name\'][$key])
            {
                $image = array(
                    \'name\' => $images[\'name\'][$key],
                    \'type\' => $images[\'type\'][$key],
                    \'tmp_name\' => $images[\'tmp_name\'][$key],
                    \'error\' => $images[\'error\'][$key],
                    \'size\' => $images[\'size\'][$key]
                );
                $_FILES = array("moreimages" => $image);
                foreach ($_FILES as $image => $array)
                {
                    $newupload = project_images($image,$pid);
                }
            }
        }
        // Get the upload attachment files
        $files = $_FILES[\'morefiles\'];
        foreach ($files[\'name\'] as $key => $value)
        {
            if ($files[\'name\'][$key])
            {
                $file = array(
                    \'name\' => $files[\'name\'][$key],
                    \'type\' => $files[\'type\'][$key],
                    \'tmp_name\' => $files[\'tmp_name\'][$key],
                    \'error\' => $files[\'error\'][$key],
                    \'size\' => $files[\'size\'][$key]
                );
                $_FILES = array("morefiles" => $file);
                foreach ($_FILES as $file => $array)
                {
                    $uploadfile = project_file($file,$pid);
                }
            }
        }
    }

function project_images($file_handler, $pid)
    {
        if ($_FILES[$file_handler][\'error\'] !== UPLOAD_ERR_OK) __return_false();
        require_once(ABSPATH . "wp-admin" . \'/includes/image.php\');
        require_once(ABSPATH . "wp-admin" . \'/includes/file.php\');
        require_once(ABSPATH . "wp-admin" . \'/includes/media.php\');
        $image_id = media_handle_upload( $file_handler, $pid );
        return $image_id;
    }
function project_file($file_handler, $pid)
    {
        if ($_FILES[$file_handler][\'error\'] !== UPLOAD_ERR_OK) __return_false();
        require_once(ABSPATH . "wp-admin" . \'/includes/image.php\');
        require_once(ABSPATH . "wp-admin" . \'/includes/file.php\');
        require_once(ABSPATH . "wp-admin" . \'/includes/media.php\');
        $file_id = media_handle_upload( $file_handler, $pid );

        //here is the only difference where I update the post meta

        update_post_meta($file_id,\'is_prj_file\',\'1\');
        return $file_id;
    }

我看不出有什么问题。你能让我提出一个类似的问题吗？谢谢

$_FILES = array("moreimages" => $image);

$files = $_FILES[\'morefiles\'];
