我正在尝试从WordPress插件将日期写入文本文件。虽然这对单个PHP文件有效,但当我将代码添加到插件时,它不会写入。TXT文件具有权限 777 并且与插件文件位于同一目录中。

我做错了什么?

这是插件,我添加的行在块中 //log 404s to text file :

 <?php
 /*
 Plugin Name: Mail me 404 errors
 Plugin URI: http://me.com
 Description: A 404 status triggers an email with details.
 Version: 1.0
 Author: Me
 Author URI: http://me.com
 */
 //SENDS 404 EMAIL TO ADMIN


 function email_admin($location){   
     // ip address
     $ipaddress = $_SERVER['REMOTE_ADDR'];
     if (!empty($_SERVER['X_FORWARDED_FOR'])) {
         $X_FORWARDED_FOR = explode(',', $_SERVER['X_FORWARDED_FOR']);
     }
     elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
         $X_FORWARDED_FOR = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
     }
     else {$ipaddress = "undefined";}
     if (!empty($X_FORWARDED_FOR)) {
         $ipaddress = trim($X_FORWARDED_FOR[0]);
     }

     // site info
     $blname=get_option('blogname');
     $admemail = get_option('admin_email');
     $honeypot = "http://www.projecthoneypot.org/ip_".$ipaddress;

     // time log
     $time = date("F jS Y, H:i", time()+25200);

     //referrer
     function current_page_url(){
         $page_url = 'http';
         if(isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on'){
         $page_url .= 's';
     }
     return $page_url.'://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
 }
 if(isset($_SESSION['referrer'])){
    $referrer = $_SESSION['referrer'];
 } elseif(isset($_SERVER['HTTP_REFERER'])){
    $referrer = $_SERVER['HTTP_REFERER'];
 } else {$referrer = "undefined";}
    $_SESSION['referrer'] = current_page_url();

 // query string
 if (isset($_SERVER['QUERY_STRING'])) { 
    $string = $_SERVER['QUERY_STRING']; 
 } else {
    $string = "undefined";
 }

    $remote = $_SERVER['REMOTE_IDENT'];

    $agent = $_SERVER['HTTP_USER_AGENT'];
 } else {
    $agent = "undefined";
 }

 //log 404s to txt file

 $ban = "#$time\r\n$ipad\r\n"; 
 $file = "errors.txt"; 
 $open = @fopen($file, "a"); 
 $write = @fputs($open, $ban); 
 @fclose($open);
 //log 404s to txt file

 $mailhead = "MIME-Version: 1.0\r\n";

传递文件的完整路径 /wp-content/plugins/your-plugin/errors.txt 到 fopen 具有 plugin_dir_path() :

$file = plugin_dir_path( __FILE__ ) . '/errors.txt'; 
$open = fopen( $file, "a" );

以下是一个最小示例:

add_action( 'get_header', 'mail_me_errors' );

function mail_me_errors() {
    if ( is_404() ) {
        email_admin( $_SERVER['REQUEST_URI'] );
    }
}

function email_admin( $location ) {   
    $time = date( "F jS Y, H:i", time()+25200 );
    $ban = "#$time\r\n$location\r\n"; 
    $file = plugin_dir_path( __FILE__ ) . '/errors.txt'; 
    $open = fopen( $file, "a" ); 
    $write = fputs( $open, $ban ); 
    fclose( $open );
}
