在下面的代码中，如何插入我创建的自定义变量 $website_url ？我想为 get_highest_score 插入它和 get_highest_score_range职能。现在，输出的格式是这样的:<li><a href="post-url">Post Name</a></li>我想将 post-url 更改为自定义网站 url。

我必须先在任何地方添加它吗？
$custom = get_post_custom($post->ID);
$website_url = $custom["website_url"][0];
-编辑- 这是我改变它的方式。我做错了什么，因为网站 url 没有输出。

以下是 get_highest_score 的函数和 get_highest_score_range .
### Function: Display Highest Score Page/Post
if(!function_exists('get_highest_score')) {
function get_highest_score($mode = '', $min_votes = 0, $limit = 10, $chars = 0, $display = true) {
global $wpdb;
$output = '';
if(!empty($mode) && $mode != 'both') {
$where = "$wpdb->posts.post_type = '$mode'";
} else {
$where = '1=1';
}
$temp = stripslashes(get_option('postratings_template_mostrated'));
$highest_score = $wpdb->get_results("SELECT DISTINCT $wpdb->posts.*, (t1.meta_value+0.00) AS ratings_average, (t2.meta_value+0.00) AS ratings_users, (t3.meta_value+0.00) AS ratings_score FROM $wpdb->posts LEFT JOIN $wpdb->postmeta AS t1 ON t1.post_id = $wpdb->posts.ID LEFT JOIN $wpdb->postmeta As t2 ON t1.post_id = t2.post_id LEFT JOIN $wpdb->postmeta AS t3 ON t3.post_id = $wpdb->posts.ID WHERE t1.meta_key = 'ratings_average' AND t2.meta_key = 'ratings_users' AND t3.meta_key = 'ratings_score' AND $wpdb->posts.post_password = '' AND $wpdb->posts.post_date < '".current_time('mysql')."'

if($highest_score) {
foreach ($highest_score as $post) {

}
} else {
$output = '<li>'.__('N/A', 'wp-postratings').'</li>'."\n";
}
if($display) {
echo $output;
} else {
return $output;
}
}
}
...和get_highest_score_range ...
### Function: Display Highest Score Page/Post With Time Range
if(!function_exists('get_highest_score_range')) {
function get_highest_score_range($time = '1 day', $mode = '', $limit = 10, $chars = 0, $display = true) {
global $wpdb;
$min_time = strtotime('-'.$time, current_time('timestamp'));
$output = '';
if(!empty($mode) && $mode != 'both') {
$where = "$wpdb->posts.post_type = '$mode'";
} else {
$where = '1=1';
}
$temp = stripslashes(get_option('postratings_template_mostrated'));
$highest_score = $wpdb->get_results("SELECT COUNT($wpdb->ratings.rating_postid) AS ratings_users, SUM($wpdb->ratings.rating_rating) AS ratings_score, ROUND(((SUM($wpdb->ratings.rating_rating)/COUNT($wpdb->ratings.rating_postid))), 2) AS ratings_average, $wpdb->posts.* FROM $wpdb->posts LEFT JOIN $wpdb->ratings ON $wpdb->ratings.rating_postid = $wpdb->posts.ID WHERE rating_timestamp >= $min_time AND $wpdb->posts.post_password = '' AND $wpdb->posts.post_date < '".current_time('mysql')."'

if($highest_score) {
foreach ($highest_score as $post) {
$output .= expand_ratings_template($temp, $post->ID, $post, $chars)."\n";
}
} else {
$output = '<li>'.__('N/A', 'wp-postratings').'</li>'."\n";
}
if($display) {
echo $output;
} else {
return $output;
}
}
}
这是 expand_ratings_template功能。

}
$post_ratings_text = '<span class="post-ratings-text" id="ratings_'.$post_id.'_text"></span>';
// Get the image's alt text

这是完整的两个文件(未经编辑):
最佳答案
毕竟您不必使用 $website_url。这是您要编辑的 expand_ratings_template 函数的一部分。
if (strpos($template, '%POST_URL%') !== false) {
$post_link = get_permalink($post_id);
$value = str_replace("%POST_URL%", $post_link, $value);
}
应成为:
if (strpos($template, '%POST_URL%') !== false) {
$custom = get_post_custom($post_id);
$post_link = $custom["website_url"][0];
$value = str_replace("%POST_URL%", $post_link, $value);
}
希望这行得通。 如果没有，插入一个
print_r($custom);
行后
$custom = get_post_custom($post_id);

当我使用Bundler时，是否需要在我的Gemfile中将其列为依赖项？毕竟，我的代码中有些地方需要它。例如，当我进行Bundler设置时:require"bundler/setup" 最佳答案 没有。您可以尝试，但首先您必须用鞋带将自己抬离地面。 关于ruby-我需要将Bundler本身添加到Gemfile中吗？，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.com/questions/4758609/
