我知道这对你们来说是一个很大的要求，但我似乎无法理解。
我找到此页面：http://www.bobz.co/ajax-filter-posts-tag/#comment-28112
它显示了如何为post标记创建动态过滤器。
我想把它改成帖子类别，但我似乎无法让它工作。
我将此代码放在函数中。php
function ajax_filter_posts_scripts() {
// Enqueue script
wp_register_script(\'afp_script\', get_stylesheet_directory_uri() . \'/js/ajax-filter-posts.js\', false, null, false);
wp_enqueue_script(\'afp_script\');
wp_localize_script( \'afp_script\', \'afp_vars\', array(
\'afp_nonce\' => wp_create_nonce( \'afp_nonce\' ), // Create nonce which we later will use to verify AJAX request
\'afp_ajax_url\' => admin_url( \'admin-ajax.php\' ),
)
);
}
add_action(\'wp_enqueue_scripts\', \'ajax_filter_posts_scripts\', 100);
// Script for getting posts
function ajax_filter_get_posts( $taxonomy ) {
// Verify nonce
if( !isset( $_POST[\'afp_nonce\'] ) || !wp_verify_nonce( $_POST[\'afp_nonce\'], \'afp_nonce\' ) )
die(\'Permission denied\');
$taxonomy = $_POST[\'taxonomy\'];
// WP Query
$args = array(
\'category_name\' => $taxonomy,
\'post_type\' => \'post\',
\'posts_per_page\' => 10,
);
// If taxonomy is not set, remove key from array and get all posts
if( !$taxonomy ) {
unset( $args[\'category_name\'] );
}
$query = new WP_Query( $args );
if ( $query->have_posts() ) : while ( $query->have_posts() ) : $query->the_post(); ?>
<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<?php the_excerpt(); ?>
<?php endwhile; ?>
<?php else: ?>
<h2>No posts found</h2>
<?php endif;
die();
}
add_action(\'wp_ajax_filter_posts\', \'ajax_filter_get_posts\');
add_action(\'wp_ajax_nopriv_filter_posts\', \'ajax_filter_get_posts\');
然后在我的实际页面模板中，我输入以下代码：
//in my template file
<?php
$args = array(
\'post_type\' => \'post\',
\'posts_per_page\' => 10,
);
$query = new WP_Query( $args );
function tags_filter() {
$tax = \'category\';
$terms = get_terms( $tax );
$count = count( $terms );
if ( $count > 0 ): ?>
<div class="post-tags">
<?php
foreach ( $terms as $term ) {
$term_link = get_term_link( $term, $tax );
echo \'<a href="\' . $term_link . \'" class="tax-filter" title="\' . $term->slug . \'">\' . $term->name . \'</a> \';
} ?>
</div>
<?php endif;
}
当我加载页面模板时，网站会加载我的内容并显示类别筛选按钮，但当我单击任何按钮时，会返回“未找到帖子”。
这让我相信我的函数文件有问题，但我无法解决。
有人能看到我做错了什么吗？

不确定你是否解决了这个问题，但我正在寻找一种方法，将其嵌入到页面中，并按类别过滤帖子。
我得到了这个工作，所以它显示所有类别和相关的职位。把它放进去functions.php
function ajax_filter_posts_scripts() {
// Enqueue script
wp_register_script(\'afp_script\', get_template_directory_uri() . \'/js/ajax-filter-posts.js\', false, null, false);
wp_enqueue_script(\'afp_script\');
wp_localize_script( \'afp_script\', \'afp_vars\', array(
\'afp_nonce\' => wp_create_nonce( \'afp_nonce\' ), // Create nonce which we later will use to verify AJAX request
\'afp_ajax_url\' => admin_url( \'admin-ajax.php\' ),
)
);
}
add_action(\'wp_enqueue_scripts\', \'ajax_filter_posts_scripts\', 100);
// Script for getting posts
function ajax_filter_get_posts( $taxonomy ) {
// Verify nonce
if( !isset( $_POST[\'afp_nonce\'] ) || !wp_verify_nonce( $_POST[\'afp_nonce\'], \'afp_nonce\' ) )
die(\'Permission denied\');
$taxonomy = $_POST[\'taxonomy\'];
// WP Query
$args = array(
\'category_name\' => $taxonomy,
\'post_type\' => \'post\',
\'posts_per_page\' => 10,
);
echo $taxonomy;
// If taxonomy is not set, remove key from array and get all posts
if( !$taxonomy ) {
unset( $args[\'tag\'] );
}
$query = new WP_Query( $args );
if ( $query->have_posts() ) : while ( $query->have_posts() ) : $query->the_post(); ?>
<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<?php the_excerpt(); ?>
<?php endwhile; ?>
<?php else: ?>
<h2>No posts found</h2>
<?php endif;
die();
}
add_action(\'wp_ajax_filter_posts\', \'ajax_filter_get_posts\');
add_action(\'wp_ajax_nopriv_filter_posts\', \'ajax_filter_get_posts\');
然后，将其添加到页面模板中：
<?php $args = array(
\'post_type\' => \'post\',
\'posts_per_page\' => 10,
);
$query = new WP_Query( $args );
$tax = \'category\';
$terms = get_terms( $tax );
$count = count( $terms );
if ( $count > 0 ): ?>
<div class="post-tags">
<?php
foreach ( $terms as $term ) {
$term_link = get_term_link( $term, $tax );
echo \'<a href="\' . $term_link . \'" class="tax-filter" title="\' . $term->slug . \'">\' . $term->name . \'</a> \';
} ?>
</div>
<?php endif;
if ( $query->have_posts() ): ?>
<div class="tagged-posts">
<?php while ( $query->have_posts() ) : $query->the_post(); ?>
<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<?php the_excerpt(); ?>
<?php endwhile; ?>
</div>
<?php else: ?>
<div class="tagged-posts">
<h2>No posts found</h2>
</div>
<?php endif; ?>
希望这有助于解决您的问题！
