我正在尝试获取位于Wordpress首页的自定义表单，其中包含自定义帖子类型，类别，自定义分类和自定义元字段的字段。我想要实现的两件事：
1st：根据搜索，将从选择字段中选择的值与来自特定元字段或/和来自/与分类/类别的值进行比较。
第二：提交表单时，未选择的值将不会包含在搜索中。
我在构建查询时遇到问题，如果我必须制作不同的搜索页面模板或者我可以使用默认搜索模板，我也很困惑。
以下是我目前使用的所有内容：
function marinedeals_filter_search($query) {
if ( is_admin() || ! $query->is_main_query() ) {
return;
}
if ( $query->is_search ) {
$query->set( 'post_type', array('post', 'yacht') );
}
return $query;
};
add_action('pre_get_posts', 'marinedeals_filter_search');
function marinedeals_add_custom_types_to_tax( $query ) {
if ( is_admin() || ! $query->is_main_query() ) {
return;
}
if ( is_category() || is_tag() && empty( $query->query_vars['suppress_filters'] ) ) {
// Get all your post types
$post_types = array( 'post', 'yacht' );
$query->set( 'post_type', $post_types );
}
return $query;
}
add_action( 'pre_get_posts', 'marinedeals_add_custom_types_to_tax' );
function marinedeals_custom_search_query( $query ) {
if ( !is_admin() && $query->is_search ) {
$query->set('meta_query', array(
array(
'key' => '__meta_key__',
'value' => $query->query_vars['s'],
'compare' => 'LIKE'
)
));
};
}
add_filter( 'pre_get_posts', 'marinedeals_custom_search_query');
function no_content_while_no_excerpt()
{
remove_filter( 'get_the_excerpt', 'wp_trim_excerpt' );
}
add_action( 'init', 'no_content_while_no_excerpt' );
function getRewriteRules() {
global $wp_rewrite; // Global WP_Rewrite class object
return $wp_rewrite->rewrite_rules();
}
function add_query_vars($aVars) {
$aVars[] = "manufacturers"; // represents the name of the product category as shown in the URL
$aVars[] = 'length';
$aVars[] = 'price';
$aVars[] = 'year';
$aVars[] = 'yacht';
return $aVars;
}
add_filter( 'query_vars', 'add_query_vars' );
