如何为自定义帖子类型创建自定义搜索？

这是我尝试过的并获得3个步骤的解决方案.假设您的自定义帖子类型为" 产品"

1. 添加功能代码,您可以在其中指定 archive-search.php

 function template_chooser($template)   
{    
  global $wp_query;   
  $post_type = get_query_var('post_type');   
  if( $wp_query->is_search && $post_type == 'products' )   
  {
    return locate_template('archive-search.php');  //  redirect to archive-search.php
  }   
  return $template;   
}
add_filter('template_include', 'template_chooser');    
 

2.为自定义帖子类型(archive-search.php)

         <?php
        /* Template Name: Custom Search */        
        get_header(); ?>             
        <div class="contentarea">
            <div id="content" class="content_right">  
                     <h3>Search Result for : <?php echo "$s"; ?> </h3>       
                     <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>    
                <div id="post-<?php the_ID(); ?>" class="posts">        
                     <article>        
                    <h4><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h4>        
                    <p><?php the_exerpt(); ?></p>        
                    <p align="right"><a href="<?php the_permalink(); ?>">Read     More</a></p>    
                    <span class="post-meta"> Post By <?php the_author(); ?>    
                     | Date : <?php echo date('j F Y'); ?></span>    

                    </article><!-- #post -->    
                </div>
        <?php endwhile; ?>
    <?php endif; ?>




           </div><!-- content -->    
        </div><!-- contentarea -->   
        <?php get_sidebar(); ?>
        <?php get_footer(); ?>
 

3. 构建搜索表单
   在此搜索表中,"产品"值是隐藏的,它将仅搜索产品帖子.

     <div>   
       <h3>Search Products</h3>
       <form role="search" action="<?php echo site_url('/'); ?>" method="get" id="searchform">
       <input type="text" name="s" placeholder="Search Products"/>
       <input type="hidden" name="post_type" value="products" /> <!-- // hidden 'products' value -->
       <input type="submit" alt="Search" value="Search" />
     </form>
    </div>

Here is what I've tried and got a solution with 3 steps. Let's say your custom post type is "products"

1 . Add Function Code here you can specify the archive-search.php

function template_chooser($template)   
{    
  global $wp_query;   
  $post_type = get_query_var('post_type');   
  if( $wp_query->is_search && $post_type == 'products' )   
  {
    return locate_template('archive-search.php');  //  redirect to archive-search.php
  }   
  return $template;   
}
add_filter('template_include', 'template_chooser');    

2 . Create search result template for custom post type ( archive-search.php )

        <?php
        /* Template Name: Custom Search */        
        get_header(); ?>             
        <div class="contentarea">
            <div id="content" class="content_right">  
                     <h3>Search Result for : <?php echo "$s"; ?> </h3>       
                     <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>    
                <div id="post-<?php the_ID(); ?>" class="posts">        
                     <article>        
                    <h4><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h4>        
                    <p><?php the_exerpt(); ?></p>        
                    <p align="right"><a href="<?php the_permalink(); ?>">Read     More</a></p>    
                    <span class="post-meta"> Post By <?php the_author(); ?>    
                     | Date : <?php echo date('j F Y'); ?></span>    

                    </article><!-- #post -->    
                </div>
        <?php endwhile; ?>
    <?php endif; ?>




           </div><!-- content -->    
        </div><!-- contentarea -->   
        <?php get_sidebar(); ?>
        <?php get_footer(); ?>

3. Build Search Form
   In this Search Form, the value "products" is hidden and it will search only product posts.

    <div>   
       <h3>Search Products</h3>
       <form role="search" action="<?php echo site_url('/'); ?>" method="get" id="searchform">
       <input type="text" name="s" placeholder="Search Products"/>
       <input type="hidden" name="post_type" value="products" /> <!-- // hidden 'products' value -->
       <input type="submit" alt="Search" value="Search" />
     </form>
    </div>

这对我有用.不太干净,但是我无法获得其他任何答案.

自定义帖子类型的搜索表单:

 <form role="search" method="get" class="search-form" action="<?php echo home_url( '/' ); ?>">
    <label>
        <span class="screen-reader-text"><?php echo _x( 'Search for:', 'label' ) ?></span>
        <input type="search" class="search-field" placeholder="<?php echo esc_attr_x( 'Search …', 'placeholder' ) ?>" value="<?php echo get_search_query() ?>" name="s" title="<?php echo esc_attr_x( 'Search for:', 'label' ) ?>" />
        <input type="hidden" name="post_type" value="book" />
    </label>
    <input type="submit" class="search-submit" value="<?php echo esc_attr_x( 'Search', 'submit button' ) ?>" />
</form>
 

在functions.php中:

 function searchfilter($query) {
    if ($query->is_search && !is_admin() ) {
        if(isset($_GET['post_type'])) {
            $type = $_GET['post_type'];
                if($type == 'book') {
                    $query->set('post_type',array('book'));
                }
        }       
    }
return $query;
}
add_filter('pre_get_posts','searchfilter');
 

在search.php中:

 <?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
    <?php if(isset($_GET['post_type'])) {
        $type = $_GET['post_type'];
           if($type == 'book') {?>

               /* Format for "book" custom post type */

           <?php } else { ?>

               /* Format for custom post types that are not "book,"
               or you can use elseif to specify a second post type the
               same way as above. Copy the default format here if you
               only have one custom post type. */

           <?php } ?>
    <?php } else { ?>

              /* Format to display when the post_type parameter
              is not set (i.e. default format) */
<?php } ?>
<?php endwhile; else: ?>

/* What to display if there are no results. */

<?php endif; ?>
 

在所有三个地方,您自然都需要用自定义帖子类型替换"图书".

希望这对某人有帮助！

Here is what works for me. Not as clean but I couldn't get any of these other answers to work.

Search form for Custom Post Type:

<form role="search" method="get" class="search-form" action="<?php echo home_url( '/' ); ?>">
    <label>
        <span class="screen-reader-text"><?php echo _x( 'Search for:', 'label' ) ?></span>
        <input type="search" class="search-field" placeholder="<?php echo esc_attr_x( 'Search …', 'placeholder' ) ?>" value="<?php echo get_search_query() ?>" name="s" title="<?php echo esc_attr_x( 'Search for:', 'label' ) ?>" />
        <input type="hidden" name="post_type" value="book" />
    </label>
    <input type="submit" class="search-submit" value="<?php echo esc_attr_x( 'Search', 'submit button' ) ?>" />
</form>

In functions.php:

function searchfilter($query) {
    if ($query->is_search && !is_admin() ) {
        if(isset($_GET['post_type'])) {
            $type = $_GET['post_type'];
                if($type == 'book') {
                    $query->set('post_type',array('book'));
                }
        }       
    }
return $query;
}
add_filter('pre_get_posts','searchfilter');

In search.php:

<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
    <?php if(isset($_GET['post_type'])) {
        $type = $_GET['post_type'];
           if($type == 'book') {?>

               /* Format for "book" custom post type */

           <?php } else { ?>

               /* Format for custom post types that are not "book,"
               or you can use elseif to specify a second post type the
               same way as above. Copy the default format here if you
               only have one custom post type. */

           <?php } ?>
    <?php } else { ?>

              /* Format to display when the post_type parameter
              is not set (i.e. default format) */
<?php } ?>
<?php endwhile; else: ?>

/* What to display if there are no results. */

<?php endif; ?>

Naturally in all three places you'll need to replace "book" with your custom post type.

Hope this helps someone!

更短的代码实现

  function template_chooser($template)   
{    
  global $wp_query; 
  $post_type = $wp_query->query_vars["pagename"];   
  if( isset($_GET['s']) && $post_type == 'products' )   
  {

    return locate_template('archive-search.php');  //  redirect to archive-search.php
  }   
  return $template;   
}
add_filter('template_include', 'template_chooser'); 
 

A short code more actualized

 function template_chooser($template)   
{    
  global $wp_query; 
  $post_type = $wp_query->query_vars["pagename"];   
  if( isset($_GET['s']) && $post_type == 'products' )   
  {

    return locate_template('archive-search.php');  //  redirect to archive-search.php
  }   
  return $template;   
}
add_filter('template_include', 'template_chooser'); 

我一直希望使用两种不同的形式进行常规搜索和针对自定义帖子类型的搜索.

我的自定义帖子类型使用的标题与普通页面不同,在我的普通页面上,对我的搜索表单的调用是:

 <?php get_search_form(true); ?>
 

在自定义帖子类型标题中对我的搜索表单的调用是:

 <?php get_template_part('search','library'); ?>
 

还有一个附加字段:

 <input type="hidden" name="post_type" value="library" /> //Where "library" is my custom post type.
 

在功能文件中,我提供了以下代码.

 /** Custom Search for Library */
function search_library($template)   
{    
  global $wp_query;   
  $post_type = get_query_var('post_type');   
  if( $wp_query->is_search && $post_type == 'library' )   
  {
    return locate_template('search-library.php');  //  redirect to archive-search.php
  }   
  return $template;   
}
add_filter('template_include', 'search_library');
 

哪个会检测搜索表单是否正在自定义字段中进行搜索,从而在自定义模板中显示搜索,否则请使用常规模板.

编辑:修复了无论如何返回为true的get_search_form()函数调用.

I was looking to use two different forms for my normal searches and my searches on a custom post type.

My custom post type uses a different header than normal pages, on my normal page, the call to my search form is:

<?php get_search_form(true); ?>

And the call to my search form in the custom post type header is:

<?php get_template_part('search','library'); ?>

Which has an additional field:

<input type="hidden" name="post_type" value="library" /> //Where "library" is my custom post type.

In the functions file I have the following code that you have provided.

/** Custom Search for Library */
function search_library($template)   
{    
  global $wp_query;   
  $post_type = get_query_var('post_type');   
  if( $wp_query->is_search && $post_type == 'library' )   
  {
    return locate_template('search-library.php');  //  redirect to archive-search.php
  }   
  return $template;   
}
add_filter('template_include', 'search_library');

Which detects if the search form is doing a search within custom fields, thus showing the search in a custom template, otherwise use the normal template.

Edit: fixed the get_search_form() function call which would have returned true no matter what.

要解决输入搜索为空的问题,可以用以下代码替换功能代码:

 function template_chooser($template)   
{    
 global $wp_query;   
 $post_type = get_query_var('post_type');   
 if( isset($_GET['s']) && $post_type == 'products' )   
 {
  return locate_template('archive-search.php');  //  redirect to archive-search.php
 }   
 return $template;   
}
add_filter('template_include', 'template_chooser');
 

To fix the empty input search issue you can substitute the function code with this:

function template_chooser($template)   
{    
 global $wp_query;   
 $post_type = get_query_var('post_type');   
 if( isset($_GET['s']) && $post_type == 'products' )   
 {
  return locate_template('archive-search.php');  //  redirect to archive-search.php
 }   
 return $template;   
}
add_filter('template_include', 'template_chooser');
