完整url yoast的php

Question

我是php的新手。我用的是Wordpress和yoast。

然而，yoast插件没有正确地编写规范。我希望编写规范，以便它使用以下语法

<link rel="canonical" href="https://www.travelideology.com/about/">

然而，它是在写

<link rel="canonical" href="https:/about/">

如果有人能让我知道我的代码出了什么问题，我会很高兴的。

代码如下：

function my_wpseo_canonical( $canonical ) {

    global $post;
    $attachment = get_post( $post->ID );

    $protocol = ($_SERVER['HTTPS'] && $_SERVER['HTTPS'] != "off") ? "https" : "http";
    $cleansed = $protocol . "://" . $_SERVER['HTTP_HOST'];
    $cleansed2 = get_permalink($attachment);
    $canonical = $cleansed . $cleansed2;
    return $canonical; 
}

add_filter( 'wpseo_canonical', 'my_wpseo_canonical' );

Answer 1

试一试

function my_wpseo_canonical( $canonical ) {

global $post;
$attachment = get_post( $post->ID );

    $protocol = ($_SERVER['HTTPS'] && $_SERVER['HTTPS'] != "off") ? "https" : "http";
$cleansed = $protocol . "://" .site_url(). $_SERVER['HTTP_HOST'];
$cleansed2 = get_permalink($attachment);
$canonical = $cleansed . $cleansed2;
return $canonical; 
    }
