Question

我使用以下方法为特定类别设置了自定义单一模板：

// custom single template for specific category
function wpse_custom_category_single_template( $single_template ) {

        // global $post;

        // get all categories of current post
        $categories = get_the_category( $post->ID );
        $top_categories = array();

        // get top level categories
        foreach( $categories as $cat ) {
                if ( $cat->parent != 0 ) {
                        $top_categories[] = $cat->parent;
                } else {
                        $top_categories[] = $cat->term_id;
                }
        }

        // check if specific category exists in array
        if ( in_array( '7', $top_categories ) ) {
                if ( file_exists( get_template_directory() . '/single-custom.php' ) ) return get_template_directory() . '/single-custom.php';
        }

        return $single_template;

}

add_filter( 'single_template', 'wpse_custom_category_single_template' );

在single-custom.php中，我正在使用：

<?php echo get_the_date('F jS, Y', $post->ID); ?>

但它正在从所有这一类别的第一篇文章中提取日期（即在每个帖子上显示相同的日期）。在不使用自定义单个模板的所有其他帖子中，日期显示正常。任何人都可以建议我在哪里犯错误。

编辑以显示single-custom.php

        <?php
    /**
     * The template for displaying all single posts and attachments
     *
     * @package FoundationPress
     * @since FoundationPress 1.0.0

    get_header(); ?>

Answer 1

我相信你可以从$post->ID删除get_the_date()：

echo get_the_date( 'F jS, Y' );

如果这不起作用，您可以尝试使用get_the_ID()功能代替$post->ID：

echo get_the_date( 'F jS, Y', get_the_ID() );

旁注：

您的代码中还有一个额外的</div>，这是故意的吗？如果没有，我已经清理了一点，以便更容易解析：

<?php
    /**
    * The template for displaying all single posts and attachments
    *
    * @package FoundationPress
    * @since FoundationPress 1.0.0
    */

    get_header();

    if( function_exists( 'yoast_breadcrumb' ) )
        yoast_breadcrumb( '<p id="breadcrumbs">', '</p>' );
?>

Answer 2

如果没有看到来自single-custom.php的代码，则很难确定，但听起来您的$post变量不包含您想要日期的项目。确保在每次循环迭代时重新分配全局$post变量。像这样的东西会把它放在你的循环中。

$your_query_object->the_post();
echo get_the_date('F jS, Y', $post->ID)

get_the_date在自定义single.php中不起作用
