我可以让add_rewrite_rule在本地与MAMP一起工作，但不能在我的DreamHost制作服务器上工作。
我试图在http://www.pawsnewengland.com/our-dogs-list/为美化宠物的网址做好准备。丑陋的URL遵循以下结构：our-dogs-list /？view = pet-details＆amp; id = 12345，自定义函数使用$_GET变量处理信息。
在我的functions.php文件中，我已将其包括在内：
function rewrite_pet_url() {
add_rewrite_rule(
"our-dogs-list/pet-details/([0-9]+)/?$",
"index.php/our-dogs-list/?view=pet-details&id=$1",
"top"
);
}
add_action( 'init', 'rewrite_pet_url');
我也尝试了同样的结果：
function rewrite_pet_url() {
add_rewrite_rule(
"our-dogs-list/pet-details/([0-9]+)/?$",
"index.php/our-dogs-list/?view=pet-details&id=$matches[1]",
"top"
);
}
add_action( 'init', 'rewrite_pet_url');
为了简单地测试重写是否会起作用，尝试了这个：
function rewrite_pet_url() {
add_rewrite_rule(
"fake",
"index.php/about",
"top"
);
}
add_action( 'init', 'rewrite_pet_url');
我在测试之前刷新重写规则，并确认重写规则已添加到.htaccess文件中。但是出于某种原因，我看到的是404页面或白色屏幕并且“未指定输入文件。”
我能够在本地工作，所以我不知道在现场服务器上有什么打破。任何见解？
我已经将重写“工作”，因为它不再导致任何错误。不幸的是，它现在导致不必要的重定向到根URL。
function rewrite_pet_url() {
add_rewrite_tag('%view%','([^&]+)');
add_rewrite_tag('%id%','([^&]+)');
add_rewrite_rule(
'our-dogs-list/pet-details/([0-9]+)?$',
'index.php/?page_id=1663&view=pet-details&id=$1',
'top'
);
}
add_action( 'init', 'rewrite_pet_url' );
有了这个，我可以使用view访问id和get_query_var()变量。但是，WordPress不会尊重example.com/our-dogs-list/pet-details/12345，而是将页面重定向到example.com/our-dogs-list/。
知道可能导致这种情况的原因是什么？它有效地使重写规则变得毫无用处。

这很长时间才能添加评论。
我会将它添加到functions.php中。我已经更改了你的永久链接，我的demo plugin解释了每个函数的作用：
add_filter('generate_rewrite_rules', 'pet_rewrite_url');
add_filter('query_vars', 'pet_query_vars'));
add_filter('admin_init', 'pet_flush_rewrite_rules');
add_action("parse_request", "pet_parse_request");
function pet_rewrite_url( $wp_rewrite ) {
$new_rules = array(
'our-dogs-list/pet-details/([0-9]+)/?$' => sprintf("index.php?pet-details=%s",$wp_rewrite->preg_index(1))
);
$wp_rewrite->rules = $new_rules + $wp_rewrite->rules;
return $wp_rewrite->rules;
}
function pet_query_vars( $query_vars ) {
$query_vars[] = 'pet-details';
return $query_vars;
}
function pet_flush_rewrite_rules() {
$rules = $GLOBALS['wp_rewrite']->wp_rewrite_rules();
if ( ! isset( $rules['our-dogs-list/pet-details/([0-9]+)/?$'] ) ) { // must be the same rule as in pet_rewrite_url($wp_rewrite)
global $wp_rewrite;
$wp_rewrite->flush_rules();
}
}
function pet_parse_request($wp_query) {
if (isset($wp_query->query_vars['pet-details'])) { // same as the first custom variable in pet_query_vars( $query_vars )
// add your code here, code below is for this demo
printf("<pre>%s</pre>",print_r($wp_query->query_vars,true));
exit(0);
}
}

您的替换看起来不正确，请尝试：
function rewrite_pet_url() {
add_rewrite_rule(
"our-dogs-list/pet-details/([0-9]+)/?$",
"index.php?view=pet-details&id=$1",
"top"
);
}
add_action( 'init', 'rewrite_pet_url');
请注意使用index.php而非index.php/our-dogs-list/作为目的地。
或许它就像这样：
function rewrite_pet_url() {
add_rewrite_rule(
"our-dogs-list/pet-details/([0-9]+)/?$",
"our-dogs-list/index.php?view=pet-details&id=$1",
"top"
);
}
add_action( 'init', 'rewrite_pet_url');

在你的.htaccess中修改
RewriteRule ^our-dogs-list/pet-details/([0-9]+)?$ /index.php?page_id=1663&view=pet-details&id=$1 [L]为RewriteRule ^index\.php$ - [L]添加此内容，以便您.hatcces可以这样：
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wordpress/
RewriteRule ^our-dogs-list/pet-details/([0-9]+)?$ /wordpress/index.php?page_id=2&view=pet-details&id=$1 [L]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wordpress/index.php [L]
</IfModule>

重要说明：默认情况下，WordPress无法识别自定义查询字符串 用于重写的变量。您必须注册您的查询字符串 WordPress的变量。只需使用add_rewrite_tag（）来执行此操作，或 以上改写不起作用！有关捕获的更多信息 重写后的查询字符串变量值可以在这里找到。
到目前为止，我了解您应该在第一个示例中使用：{_ 1}}和view的add_rewrite_tag（）。
