如何在代码点火器中将自定义错误处理程序设置为电子邮件错误 - How to set custom error handler in Codeigniter to Email errors

How to set custom error handler in Codeigniter to Email errors

我对PHP和自定义错误处理程序的设置相当陌生，但是我有一些代码可以在CI之外正常工作，但我无法弄清楚如何将其集成到CI控制器中。我收到错误"消息：未定义的属性：错误：$my_错误处理程序"

我的控制器是：

<?php
class Errors extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
    }
    function my_error_handler($number, $message, $file, $line, $vars)
    {
        $email = "
            <p>An error ($number) occurred on line
            <strong>$line</strong> and in the <strong>file: $file.</strong>
            <p> $message </p>";
        $email .= "<pre>" . print_r($vars, 1) . "</pre>";
        $headers = 'Content-type: text/html; charset=iso-8859-1' . "'r'n";
        // Email the error to someone...
        error_log($email, 1, 'name@domain.com', $headers);
        // Make sure that you decide how to respond to errors (on the user's side)
        // Either echo an error message, or kill the entire project. Up to you...
        // The code below ensures that we only "die" if the error was more than
        // just a NOTICE.
        if ( ($number !== E_NOTICE) && ($number < 2048) ) {
            die("There was an error. Please try again later.");
        }
    }

    function test()
    {
        // We should use our custom function to handle errors.
        set_error_handler($this->my_error_handler);
        // Trigger an error... (var doesn't exist)
        echo $somevarthatdoesnotexist;
    }
}
?>

如果有更好的方法使用 CI 通过电子邮件发送错误消息，请告诉我。

我不认为扩展CI_Controller是解决这个问题的正确方法。相反，您应该扩展CI_Logs以在记录错误时发送电子邮件：

class MY_Log extends CI_Log {
    function MY_Log(){
        parent::__construct();
    }
    function write_log($level = 'error', $msg, $php_error = FALSE){
        $result = parent::write_log($level, $msg, $php_error);
        if ($result == TRUE && strtoupper($level) == 'ERROR') {
            $message = "An error occurred: 'n'n";
            $message .= $level.' - '.date($this->_date_fmt). ' --> '.$msg."'n";
            $this->CI =& get_instance();
            $to = $this->CI->config->item('email_admin_address');
            $from_name = $this->CI->config->item('email_general_name');
            $from_address = $this->CI->config->item('email_general_address');
            $subject = 'An error has occured';
            $headers = "From: $from_name <$from_address>" . "'r'n";
            $headers .= 'Content-type: text/plain; charset=utf-8'r'n';
            mail($to, $subject, $message, $headers);
        }
        return $result;
    }

}

将此类保存到应用程序''库''MY_Logs.php不要忘记在配置中启用错误日志记录.php： $config['log_threshold'] = 1;

感谢WPStorm，他首先提出了这个想法。

我已经找到了解决方案。

set_error_handler(array(&$this, 'my_error_handler'));

因为你必须告诉错误处理程序它是你想要调用的类方法（set_error_handler(array(&$this, ‘method’))的预期含义），而不仅仅是一个函数（set_error_handler(‘function’)的预期含义）

如果扩展核心异常类，您将能够在其中添加所需的功能。
