问题描述
对不起，如果我的问题是基本的或愚蠢的，但请帮助我解决这个问题.我正在尝试在 wordpress 中动态更改 </code> 和 <code><meta name="description" ></code> 标签.所以这就是我在 function.php 文件中尝试的.<em class="showen"></em></p>
<p class="en">Sorry if my question was basic or stupid but please help me to solve this issue. I'm trying to change <code><title></code> and <code><meta name="description" ></code> tags dynamically in wordpress. so this is what I tried in function.php file.</p>
<pre><code><code>function changeMeta_2(){
global $wpdb;
$cur_url = $_SERVER['REQUEST_URI'];
$basename = pathinfo($cur_url);
$ebasename = $basename['filename'];
if(is_numeric($ebasename)) {
$url = explode('/', $basename['dirname']);
$basename = explode('.', $url[count($url)-2]);
$ebasename = $basename[0];
}
$pageName = $ebasename;
$arraylist_subcat = array("car","bike","boat","xxxx","yyyy","zzz","mmmm");
$arraylist_maincat = array("aus","ind","usa","uae");
$category_id = get_term_by('slug',$pageName, 'category');
$category_parentid = get_term_by('id', $category_id->parent, 'category');
$parent_slug = $category_parentid->slug;
if ( is_page()) {
if ( in_array($pageName,$arraylist_maincat) ) {
$metaTitle = 'Browse '.$pageName.' | Some txt title | mysite.com';
$metaDescription = 'some of custome blablaaaaa text description '.$pageName.' some of custome blablaaaaa text description ';
echo '<title>'.$metaTitle.'</title>';
echo '<meta name="description" content="'.$metaDescription.'"/>';
}
}
}
add_action( 'wp_head', 'changeMeta_2' );
</code></code></pre>
<p class="cn">在上面的代码中，我试图更改与数组值(in_array 条件)匹配的术语 ID 的标题标签和元描述.<em class="showen"></em></p>
<p class="en">In the above code I'm trying to change the title tag and meta description for term id which are matching with array values (in_array condition).</p>
<p class="cn">一切正常，但问题是不是覆盖(替换)<code><title></code> 标签附加在头部.它不会改变它附加.请有人帮我解决这个问题.<em class="showen"></em></p>
<p class="en">Everything works fine, but problem is instead of override(replace) <code><title></code> tag is appending in head. Its not changing it appending. please someone help me to solve this issue.</p>
<h3 class="best_ans mt-1">推荐答案</h3>
<p class="cn">对于将来遇到此问题的任何人:此功能可以使用 <a href="https://wordpress.org/plugins/wordpress-seo/" rel="nofollow">Yoast SEO 插件</a>.<em class="showen"></em></p>
<p class="en">For anybody coming to this question in the future: This functionality can be accomplished using the Yoast SEO plugin.</p>
<p class="cn"><strong>但是</strong>，如果您仍然想自己做....<em class="showen"></em></p>
<p class="en"><strong>However</strong>, if you do want to still do this yourself....</p>
<p class="cn">为了修改标题，而不是 <code>wp_head</code> 钩子，您需要使用实际上允许您<strong>修改</strong>标题的过滤器:<a href="https://developer.wordpress.org/reference/hooks/wp_title/" rel="nofollow">wp_title</a><em class="showen"></em></p>
<p class="en">In order to modify the title, rather than the <code>wp_head</code> hook, you need to be using the filters that actually allow you to <strong>modify</strong> the title: wp_title</p>
<p class="cn">并且您可以/应该使用 <code>wp_head</code> 来<strong>添加</strong>元描述(请参阅此处的文档:<a href="http://codex.wordpress.org/Meta_Tags_in_WordPress" rel="nofollow">http://codex.wordpress.org/Meta_Tags_in_WordPress</a>)<em class="showen"></em></p>
<p class="en">And you can / should use the <code>wp_head</code> in order to <strong>add</strong> the meta description (see the docs here: http://codex.wordpress.org/Meta_Tags_in_WordPress)</p>
<p class="cn"><strong>另请注意</strong>有更简单的方法来获取页面标题，如下所述...<em class="showen"></em></p>
<p class="en"><strong>Also note</strong> there's easier ways to get the page title, mentioned below...</p>
<p class="cn">对于标题，您的代码如下所示:<em class="showen"></em></p>
<p class="en">For the title, your code would look something like so:</p>
<pre><code><code>function changeTitle($title, $sep, $seplocation){
global $wpdb;
// NOTE: This is the HARD way to get the page title, and is unreliable...
$cur_url = $_SERVER['REQUEST_URI'];
$basename = pathinfo($cur_url);
$ebasename = $basename['filename'];
if(is_numeric($ebasename)) {
$url = explode('/', $basename['dirname']);
$basename = explode('.', $url[count($url)-2]);
$ebasename = $basename[0];
}
$pageName = $ebasename;
// NOTE: Why not get pagename this way?
global $post;
$pageName = $post->post_title;
// or if you need the slug...
$pageName = $post->post_slug;
$arraylist_subcat = array("car","bike","boat","xxxx","yyyy","zzz","mmmm");
$arraylist_maincat = array("aus","ind","usa","uae");
$category_id = get_term_by('slug',$pageName, 'category');
$category_parentid = get_term_by('id', $category_id->parent, 'category');
$parent_slug = $category_parentid->slug;
if ( is_page()) {
if ( in_array($pageName,$arraylist_maincat) ) {
$title = 'Browse '.$pageName.' | Some txt title | mysite.com';
}
}
return $title;
}
add_action( 'wp_title', 'changeTitle', 10, 3 );
