链接到Foreach循环中的单独文件时出现问题

时间：2016-08-23 作者：jrcollins

我正在自定义主题的类别模板，以显示当前类别的子类别，而不是该类别中的帖子。

类别模板链接到另一个模板文件(content-grid.php) 生成动态帖子/类别内容。

我能让它工作的唯一方法是在类别模板上将所有代码组合在一起。

这是原始类别模板：

<?php
/**
 * The template for displaying category archive pages.
 *
 * @link https://codex.wordpress.org/Template_Hierarchy
 *
 * @package Codilight_Lite
 */

get_header(); ?>
    <div id="content" class="site-content container <?php echo codilight_lite_sidebar_position(); ?>">
        <div class="content-inside">
            <div id="primary" class="content-area">
                <main id="main" class="site-main" role="main">

                <?php
                if ( have_posts() ) : $count = 0; ?>

                    <header class="page-header">
                        <?php
                            the_archive_title( \'<h1 class="page-title">\', \'</h1>\' );
                            the_archive_description( \'<div class="taxonomy-description">\', \'</div>\' );
                        ?>
                    </header><!-- .page-header -->

                    <?php
                    $layout_archive_posts = get_theme_mod( \'layout_archive_posts\', \'grid\' );
                    if ( $layout_archive_posts == \'grid\' ) {
                        echo \'<div class="block1 block1_grid">\';
                        echo \'<div class="row">\';
                            while ( have_posts() ) : the_post();
                            $count++;
                                get_template_part( \'template-parts/content-grid\' );
                            if ( $count % 2 == 0 ) {
                                echo \'</div>\';
                                echo \'<div class="row">\';
                            }
                            endwhile;
                        echo \'</div>\';
                        echo \'</div>\';
                        codilight_lite_custom_paginate();

                    } else {
                        echo \'<div class="block1 block1_list">\';
                            while ( have_posts() ) : the_post();
                            get_template_part( \'template-parts/content-list\' );
                            endwhile;
                        codilight_lite_custom_paginate();
                        echo \'</div>\';
                    }
                    ?>

                <?php else : ?>

                    <?php get_template_part( \'template-parts/content\', \'none\' ); ?>

                <?php endif; ?>

                </main><!-- #main -->
            </div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>
。。。这是content-grid.php 模板文件：

<?php
/**
 * Template part for displaying posts with grid style.
 *
 * @link https://codex.wordpress.org/Template_Hierarchy
 *
 * @package Codilight_Lite
 */

?>

<article id="post-<?php the_ID(); ?>" <?php post_class( \'col-md-6 col-sm-12\' ); ?>>
    <div class="entry-thumb">
        <a href="<?php echo esc_url( get_permalink() ); ?>" title="<?php the_title(); ?>">
            <?php
            if ( has_post_thumbnail( ) ) {
                the_post_thumbnail( \'codilight_lite_block_2_medium\' );
            } else {
                echo \'<img alt="\'. esc_html( get_the_title() ) .\'" src="\'. esc_url( get_template_directory_uri() . \'/assets/images/blank325_170.png\' ) .\'">\';
            }
            ?>
        </a>
        <?php
        $category = get_the_category();
        if($category[0]){
            echo \'<a class="entry-category" href="\'.get_category_link($category[0]->term_id ).\'">\'.$category[0]->cat_name.\'</a>\';
        }
        ?>
    </div>
    <div class="entry-detail">
        <header class="entry-header">
            <?php the_title( sprintf( \'<h2 class="entry-title"><a href="%s" rel="bookmark">\', esc_url( get_permalink() ) ), \'</a></h2>\' ); ?>
            <?php if ( \'post\' === get_post_type() ) codilight_lite_meta_1();?>
        </header><!-- .entry-header -->

        <div class="entry-excerpt">
            <?php echo codilight_lite_excerpt(120); ?>
        </div><!-- .entry-content -->
    </div>
</article><!-- #post-## -->
。。。现在是自定义类别模板文件：

<?php
/**
 * Category Template: Custom
 */

get_header(); ?>
    <div id="content" class="site-content container <?php echo codilight_lite_sidebar_position(); ?>">
        <div class="content-inside">
            <div id="primary" class="content-area">
                <main id="main" class="site-main" role="main">
<?php 
        $cat = get_category( get_query_var( \'cat\' ) );
        $cat_id = $cat->cat_ID;
        $child_categories=get_categories(
        array( 
        \'parent\' => $cat_id,
        // Uncomment the below line if you want empty category to appear on the list. 
        // \'hide_empty\'   => 0
    )
); 
        if (!empty($child_categories)) : $count = 0; ?>

                    <header class="page-header">
                        <?php
                            the_archive_title( \'<h1 class="page-title">\', \'</h1>\' );
                            the_archive_description( \'<div class="taxonomy-description">\', \'</div>\' );
                        ?>
                    </header><!-- .page-header -->

                    <?php
                        echo \'<div class="block1 block1_grid">\';
                        echo \'<div class="row">\';

                    foreach ( $child_categories as $child ){ $count++;
                    get_template_part( \'template-parts/content-grid\' );

                    if ( $count % 2 == 0 ) {
                                echo \'</div>\';
                                echo \'<div class="row">\';
                    }
                    }
                        echo \'</div>\';
                        echo \'</div>\';
                    ?>

                <?php else : ?>

                    <?php get_template_part( \'template-parts/content\', \'none\' ); ?>

                <?php endif; ?>

                </main><!-- #main -->
            </div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>
。。。以及定制的content-grid.php 模板文件：

<?php
/**
 * Template part for displaying posts with grid style.
 *
 * @link https://codex.wordpress.org/Template_Hierarchy
 *
 * @package Codilight_Lite
 */

?>

<article id="" class="col-md-6 col-sm-12">

    <div class="entry-thumb">

        <a href="<?php echo get_category_link( $child->cat_ID ); ?>" title="<?php echo $child ->cat_name;?>">

    <?php $image_url = z_taxonomy_image_url($child->term_id); ?>

        <?php if (!empty($image_url)) : ?>
            <img alt="" src="<?php if (function_exists(\'z_taxonomy_image_url\')) echo z_taxonomy_image_url($child->term_id);?>" />

        <?php else: ?>
            <img alt="" src="<?php echo esc_url( get_template_directory_uri() . \'/assets/images/blank325_170.png\' ) ?>" />

    <?php endif; ?>

        </a>

    </div>

    <div class="entry-detail">

        <header class="entry-header">

            <h2 class="entry-title"><a href="<?php echo get_category_link( $child->cat_ID ); ?> " rel="bookmark"><?php echo $child ->cat_name;?></a>
            </h2>

        </header><!-- .entry-header -->

        <div class="entry-excerpt">

            <?php echo $child ->description;?>

        </div><!-- .entry-content -->

    </div>

</article><!-- #post-## -->
。。。最后，这是我如何将所有代码放在分类模板文件中的方法，该文件有效：

<?php
/**
 * Category Template: Custom
 */

get_header(); ?>
    <div id="content" class="site-content container <?php echo codilight_lite_sidebar_position(); ?>">
        <div class="content-inside">

                <main id="main" class="site-main" role="main">

        $cat = get_category( get_query_var( \'cat\' ) );
        $cat_id = $cat->cat_ID;
        $child_categories=get_categories(
        array( 
        \'parent\' => $cat_id,
        // Uncomment the below line if you want empty category to appear on the list. 
        // \'hide_empty\'   => 0
    )
); 
        if (!empty($child_categories)) : $count = 0; ?>

                    <header class="page-header">
                        <?php
                            the_archive_title( \'<h1 class="page-title">\', \'</h1>\' );
                            the_archive_description( \'<div class="taxonomy-description">\', \'</div>\' );

                    foreach ( $child_categories as $child ) : $count++; ?>

                    ?>

                <?php else : ?>

                    <?php get_template_part( \'template-parts/content\', \'none\' ); ?>

                <?php endif; ?>

据我所知get_template_part() 函数不适用于foreach 环所以我们需要使用locate_template() 此情况下的函数。这是您自定义的类别模板代码。把它放在那里-

<?php
/**
 * Category Template: Custom
 */

get_header(); ?>
    <div id="content" class="site-content container <?php echo codilight_lite_sidebar_position(); ?>">
        <div class="content-inside">
            <div id="primary" class="content-area">
                <main id="main" class="site-main" role="main">
        <?php 
        $cat = get_category( get_query_var( \'cat\' ) );
        $cat_id = $cat->cat_ID;
        $child_categories=get_categories(
        array( 
            \'parent\' => $cat_id,
            // Uncomment the below line if you want empty category to appear on the list. 
            // \'hide_empty\'   => 0
            )
        ); 
        if (!empty($child_categories)) : $count = 0; ?>

                    <header class="page-header">
                        <?php
                            the_archive_title( \'<h1 class="page-title">\', \'</h1>\' );
                            the_archive_description( \'<div class="taxonomy-description">\', \'</div>\' );
                        ?>
                    </header><!-- .page-header -->

                    <div class="block1 block1_grid">
                    <?php
                    foreach(array_chunk($child_categories, 2) as $item) {
                        echo \'<div class="row">\';
                        foreach ($item as $child) {
                            // get_template_part( \'template-parts/content-grid\' );
                            include( locate_template( \'template-parts/content-grid.php\' ) );
                        }
                        echo \'</div>\';
                    }
                    ?>
                    </div>

                <?php else : ?>

                    <?php get_template_part( \'template-parts/content\', \'none\' ); ?>

                <?php endif; ?>

                </main><!-- #main -->
            </div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>
