如何更改消息：上传的文件超过了 php.ini 中的 upload_max_filesize 指令

Question

您好，只要您降低上传文件大小，然后尝试上传大于 php.ini 中指定大小的文件，就会出现此通用消息 我不寻求如何解决它， 我想更改消息的内容，但我找不到在哪里。 网络上到处都是如何修复它的答案:) 谢谢！

如果您只想捕获异常并更改为“不错”的消息，则需要将上传内容包装在 try catch 中并测试以下异常类型 UPLOAD_ERR_INI_SIZE。

您可以从那里简单地编辑/更改/替换您喜欢的消息。

值得注意的是，您可能希望处理更多错误消息，它们在documentation 中列出。

这是“直接”的 PHP，所以 WordPress 可能需要少量，我现在没有方便的 WP 安装。

try {
    //upload stuff
} catch (Exception $e) {
    switch($_FILES['file']['error']) {
        case UPLOAD_ERR_OK:
            //for completeness sake
            $message = "File Uploaded Successfully";
            break;
        case UPLOAD_ERR_INI_SIZE:
            $message = "The uploaded file exceeds the upload_max_filesize directive in php.ini";
            break;
        case UPLOAD_ERR_FORM_SIZE:
            $message = "The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form";
            break;
        case UPLOAD_ERR_PARTIAL:
            $message = "The uploaded file was only partially uploaded";
            break;
        case UPLOAD_ERR_NO_FILE:
            $message = "No file was uploaded";
            break;
        case UPLOAD_ERR_NO_TMP_DIR:
            $message = "Missing a temporary folder";
            break;
        case UPLOAD_ERR_CANT_WRITE:
            $message = "Failed to write file to disk";
            break;
        case UPLOAD_ERR_EXTENSION:
            $message = "File upload stopped by extension";
            break;
        default:
            $message = "Unknown upload error";
            break;
    }
    //deal with returning the message here
}

只需将$message 编辑成您想要的任何自定义消息即可。
