该函数现在的目的是遍历多个以逗号分隔的邮政编码列表（zip_codes_serviced 的高级自定义字段）并将其与特定的邮政编码匹配（33606 用于测试目的）。如果匹配，该函数应打印与该邮政编码关联的城市和州字段。在这种情况下，佛罗里达州坦帕市。见下面的功能：

function zip_search($userZip){
    $posts = get_posts(array(
        'posts_per_page'    => -1,
        'post_type'         => 'Location'
    ));


    if( $posts ): 
        foreach( $posts as $post ): 
            $zipField=get_field('zip_codes_serviced');
            //echo $zipField;
            $zipString = $zipField . ', ';
            //echo $zipArray;

            $array = explode(', ' , $zipString); //split string into array seperated by ', '

            foreach($array as $value) //loop over values
            {
                $cityField=get_field('city');
                $stateField=get_field('state');

                if($value==$userZip){

                return ($cityField . '<br>' . $stateField);  
            }   
            }       
        endforeach;
        wp_reset_postdata(); 
    endif; 
}

然后我这样调用函数：

zip_search(33606);

我也试过这样：

function zip_search(){
        $posts = get_posts(array(
            'posts_per_page'    => -1,
            'post_type'         => 'Location'
        ));
        //Set user zip to 33606 for testing purposes
        $userZip=33606;

        if( $posts ): 
            foreach( $posts as $post ): 
                $zipField=get_field('zip_codes_serviced');
                //echo $zipField;
                $zipString = $zipField . ', ';
                //echo $zipArray;

                $array = explode(', ' , $zipString); //split string into array seperated by ', '

                foreach($array as $value) //loop over values
                {
                    $cityField=get_field('city');
                    $stateField=get_field('state');
                    //echo $value. '<br>';            
                    if($value==$userZip){

                    echo ($cityField . '<br>' . $stateField); //print 
                }   
                }       
            endforeach;
            wp_reset_postdata(); 
        endif; 
    }

然后像这样调用：

zip_search();

这不应该在页面上打印出城市和州字段吗？当我将逻辑放在函数之外时，它可以工作，但我无法让它在函数内工作。有人有建议吗？

我可以让它工作的唯一方法是完全在一个函数之外——创建一个文件zip-search.php，然后<?php include("phone-display.php"); ?>在我希望它显示的页面上插入，但我很确定这是一个 hack；zip-search.php见下：

$posts = get_posts(array(
    'posts_per_page'    => -1,
    'post_type'         => 'Location'
));
//Set user zip to 33606 for testing purposes
$userZip=33606;
if( $posts ): 
     foreach( $posts as $post ): 
        $zipField=get_field('zip_codes_serviced');
        //echo $zipField;
        $zipString = $zipField . ', ';
        //echo $zipArray;

        $array = explode(', ' , $zipString); //split string into array seperated by ', '

        foreach($array as $value) //loop over values
        {
            $cityField=get_field('city');
            $stateField=get_field('state');
            //echo $value. '<br>';            
            if($value==$userZip){

               echo ($cityField . '<br>' . $stateField); //print 
           }    
         }       
     endforeach;
    wp_reset_postdata(); 
 endif;

我试图让邮政编码功能工作的整个模板文件如下所示：

<?php 
 /*
Template Name: Location
*
*/
get_header(); 
nectar_page_header($post->ID); 

//full page
$fp_options = nectar_get_full_page_options();
extract($fp_options);

?>
<?php
function zip_search($userZip){
    $posts = get_posts(array(
        'posts_per_page'    => -1,
        'post_type'         => 'Location'
    ));
    //Set user zip to 33606 for testing purposes
    //$userZip=33606;

    if( $posts ): 
        foreach( $posts as $post ): 
            $zipField=get_field('zip_codes_serviced');
            //echo $zipField;
            $zipString = $zipField . ', ';
            //echo $zipArray;

            $array = explode(', ' , $zipString); //split string into array seperated by ', '

            foreach($array as $value) //loop over values
            {
                $cityField=get_field('city');
                $stateField=get_field('state');
                //echo $value. '<br>';            
                if($value==$userZip){

                echo ($cityField . '<br>' . $stateField); //print 
            }   
            }       
        endforeach;
        wp_reset_postdata(); 
    endif; 
}
?>

请看var_dump($post);下面的函数结果，由于字符限制，我只包含了一小部分：

我最终这样做了，最后决定返回帖子的永久链接而不是城市和州会更好：

function zip_search($userZip){

    $args = array(
    'posts_per_page'    => -1,
    'post_type'         => 'Locations'
    );

$wp_query = new WP_Query($args); 

if( $wp_query->have_posts() ): while( $wp_query->have_posts() ) : $wp_query->the_post();
      $zipField=get_field('zip_codes_services');

          $zipString = $zipField . ', ';        

          $array = explode(', ' , $zipString); //split string into array seperated by ', '

        foreach($array as $value) //loop over values
        {

            if($value==$userZip){
                $post_id = get_the_ID();
                $permalink=get_permalink($post_id);                 
               return ($permalink); //print 
           }    

        }
       endwhile; 
       wp_reset_postdata(); 
endif;
}
