WordPress的画廊没有显示 [英] Wordpress Gallery is not displaying

问题描述

我从头开始开发了一个自定义的wordpress主题.我有一个问题.当我尝试在帖子或页面中使用本机wordpress画廊简码时，它在编辑器中可以很好地显示，但不会在前端显示.

I have developed a custom wordpress theme from scratch. I'm having a issue in it. When I try to use native wordpress gallery shortcode in my post or page, It is display fine in the editor but its not displaying on the front end.

我什至尝试使用:

echo do_shortcode('[gallery columns="5" link="none" ids="70,69,68,67"]');

但是什么都没有出现...

But nothing has shown up...

其他帖子/页面内容显示良好，但没有显示图库.就像它甚至没有在前端产生任何东西一样.

Other post / page content is displaying fine but just gallery is not displaying. Its like its not even generating anything on the front-end.

如果我将主题切换为任何其他主题，它将起作用，但不适用于我的主题，因此很明显这是一个主题问题.我必须为图库添加某种主题支持吗?

If I switched the theme to any other theme it work but not in my theme, so its clear that its a theme problem. Do I have to add some kind of theme support for the gallery?

任何帮助将不胜感激:)

Any help would be appreciated :)

推荐答案

等待了很多，但找不到答案...我找到了问题，但不知道如何解决.但幸运的是，有一种解决方法.

Waited a lot but couldn't find an answer... I found the issue but doesn't know how to resolve it. But fortunately there is a way around it.

我一直在使用wordpress的pre_get_posts钩子来设置tax_query，它看起来像这样:

I have been using wordpress's pre_get_posts hook to set a tax_query which looks like this:

add_action( 'pre_get_posts', 'homeInjector' );

function homeInjector( $query ) {

        if ( $query->is_home() ) {

            $issues = get_terms( array(
                'taxonomy' => 'issues'
            ) );

            if ( isset( $_POST['issue'] ) ) {
                $term = $_POST['issue'];
            } else {
                $term = $issues[0]->slug;
            }


            $arg = array(
                array(
                    'taxonomy' => 'issues',
                    'terms'    => $term,
                    'field'    => 'slug'
                )
            );

            $query->set( 'tax_query', $arg );

        }

但是如果我在index.php中使用new WP_Query对象使用相同的代码，它将起作用！

but if I use same code in index.php with new WP_Query object it works!

$issues = get_terms( array(
    'taxonomy' => 'issues'
) );

if ( isset( $_POST['issue'] ) ) {
    $term = $_POST['issue'];
} else {
    $term = $issues[0]->slug;
}

$qry = new WP_Query( array(
    'post_type' => 'post',
    'tax_query' => array(
        array(
            'taxonomy' => 'issues',
            'terms'    => $term,
            'field'    => 'slug'
        )
    )
) );

不知道为什么，但是有效...

Don't know why but it works...

但是我仍然要等待适当的答案，因为我的存在只是帮助我和其他人的一种方法:)

But still I'll wait for the appropriate answer because mine is just a way around to help me and others :)
