How to close thinkphp's error

When developing using the ThinkPHP framework, we often encounter program errors. When the program reports an error, an error prompt window will pop up. If we do not handle it, this window will remain until it is manually closed. This will undoubtedly affect the user experience and make developers very inconvenient. So how to close this error prompt window in the ThinkPHP framework?

First of all, we need to know that the error prompt page of the ThinkPHP framework is output by the display method in the ThinkPHP\Library\Think\Error class. So as long as you make slight modifications in this method, you can realize the function of closing the error prompt window.

The specific implementation steps are as follows:

1. Find the ThinkPHP\Library\Think\Error class file, open it and find the display method.
2. Find the following code in the display method:

if (isset($config['show_page_trace']) && $config['show_page_trace']) {
    // ...
} else {
    // 显示错误信息
    include $this->getErrorTemplate($exception);
}

This code block is used to determine whether to display detailed error tracking information. We need to replace include $this->getErrorTemplate($exception) with the following code:

if (IS_AJAX) { //如果是 Ajax 请求，直接返回 JSON 格式的数据
    $result = array(
        'code' => -1,
        'msg' => $exception->getMessage()
    );
    exit(json_encode($result));
} else { //如果是普通请求，则直接输出错误信息
    exit($exception->getMessage());
}

Among them, IS_AJAX is one in the ThinkPHP framework Constant used to determine whether the current request is an Ajax request.

3. Save the modified Error class file and re-run the program.

Now, when the program reports an error, the error prompt window will no longer pop up, but the error information will be output directly to the page (if it is an Ajax request, it will be returned in JSON format).

It should be noted that closing the error prompt window will bring a better experience to users, but it will also increase the difficulty of debugging for developers. Therefore, in a formal environment, we should open the error prompt window so that errors can be discovered and repaired in time.

Summary:

The error window in the ThinkPHP framework can be closed by modifying the display method of the Error class. But in a formal environment, the error prompt window should be opened so that errors can be discovered and repaired in time. When developers use it, they need to handle it flexibly according to the actual situation.
