我正在制作一个单页网站。在这个页面上，我想运行三到四次WP\\u Query来拉入这3-4个页面。

页面看起来有点像这样：

<div class="row">
 <?php

    $args = array( \'pagename\' => \'page-1\'); 

    $the_query = new WP_Query( $args );

    // The Loop
    if ( $the_query->have_posts() ) :
    while ( $the_query->have_posts() ) : $the_query->the_post();
      get_template_part(\'content\');
    endwhile;
    endif;

    // Reset Post Data
    wp_reset_postdata();
?>
</div>


<div class="row">
 <?php

    $args = array( \'pagename\' => \'page-2\'); 

    $the_query = new WP_Query( $args );

    // The Loop
    if ( $the_query->have_posts() ) :
    while ( $the_query->have_posts() ) : $the_query->the_post();
      get_template_part(\'content\');
    endwhile;
    endif;

    // Reset Post Data
    wp_reset_postdata();
?>
</div>

<div class="row">
 <?php

    $args = array( \'pagename\' => \'page-3\'); 

    $the_query = new WP_Query( $args );

    // The Loop
    if ( $the_query->have_posts() ) :
    while ( $the_query->have_posts() ) : $the_query->the_post();
      get_template_part(\'content\');
    endwhile;
    endif;

    // Reset Post Data
    wp_reset_postdata();
?>
</div>

当然，我在这里重复我自己的话，这有点浪费。我要做的是对WP\\u Query的这个实例进行函数化。这是我所做的，但它似乎没有任何回报。它一定是很愚蠢的东西，但我看不出它可能是什么（在functions.php中）：

/**
 * Functionize wp_query
 *
 * @since 0.1
 */
function waterstreet_fetch_page( $pagename ){
    $args = array( \'pagename\' => $pagename ); 

    $the_query = new WP_Query( $args );

    // The Loop
    if ( $the_query->have_posts() ) :
    while ( $the_query->have_posts() ) : $the_query->the_post();
      get_template_part(\'content\');
    endwhile;
    endif;

    // Reset Post Data
    wp_reset_postdata();
}

当然，在我的模板文件中，我希望能够运行：

<div class="row">
    <?php waterstreet_fetch_page(\'page-1\'); ?>
</div>

<div class="row">
    <?php waterstreet_fetch_page(\'page-2\'); ?>
</div>

<div class="row">
    <?php waterstreet_fetch_page(\'page-3\'); ?>
</div>

欢迎咨询！谢谢
