按自定义字段WordPress筛选

Question

我想按自定义字段类型搜索帖子。我有自定义字段"；国家；现在我想要一个自定义的帖子类型umrahpackage，如果访问者搜索一个国家"；abc"；它应该显示abc国家的所有帖子。

这是我的代码，但不起作用。`

add_shortcode('user_search','My_User_search');
function My_User_search($atts = null)
{
$out = user_search_form();


$args = array(
'post_type' => 'umrahpackage',
'meta_query' => array(
array(
'key'     => 'country',
'value'   => 'pakistan',
'compare' => 'LIKE',
))
);
$the_query = new WP_Query( $args );
if( $the_query->have_posts() ):
while( $the_query->have_posts() ) : $the_query->the_post();
$out .= '<li>' . get_the_title() . '</li>';
endwhile;
endif;    
return $out;
}
//function to display user search form
function user_search_form(){
$metavalue = $metakey = '';
if (isset($_GET['search_by'])){
$metakey = $_GET['search_by'];
}
if (isset($_GET['s_value'])){
$metavalue = $_GET['s_value'];
}
$re = '<div class="user_search"><form action="" name="user_s" method="get">
<label for="search_by">Search by:</label>



<select id="search_by" name="search_by">';
if ($metakey != ''){
$re.= '"';
$re.= ($metakey == "country") ;

}else{
$re .= '
<option value="country">Comapny Name</option>';
}
$re .= '
</select>
<label>Company Name</label>
<input id="s_value" name="s_value" type="text" value="'.$metavalue.'"/>
<input type="hidden" id="user_search" name="post_type" value="umrahpackage" /> 

<input id="submit" type="submit" value="Search" />
</form></div>';
return $re;
}`

add_shortcode('user_search','My_User_search');
function My_User_search($atts = null){
$out = user_search_form();
$args = array('post_type' => 'umrahpackage','order' => 'asc', 
'meta_query' => array(
array(
'key' => 'country',
'value' => $_GET['s_value'],
'compare' => 'Like',
)
)
);
$the_query = new WP_Query( $args );
if( $the_query->have_posts() ):
while( $the_query->have_posts() ) : $the_query->the_post();

if($_GET['s_value']==''){
//before search hide the posts 
}
else {
$out .= '<li>' . get_the_title() . '</li>';
}  
endwhile;
endif;    
return $out;
}
function user_search_form(){

$re = '<div class="user_search"><form action="" name="user_s" method="get">
<label for="search_by">Search by:</label>
<div id="search_by" name="search_by">';
$re .= '
<label>Company Name</label>
<input id="s_value" name="s_value" type="text" value="'.$metavalue.'"/>

<input name="user_search" id="user_search" type="hidden" value="umrahpackage"/>
<input id="submit" type="submit" value="Search" />
</form></div>';
return $re;
}
?>
