是的,这在WordPress中是可能的,但我不会使用索引。php只是一个定制的首页。php模板然后创建一个名为home的页面,并将其设置为options general中的首页。
对于您的类别菜单:
<?php
$categories = get_categories(); ?>
<ul id="category-menu">
<?php foreach ( $categories as $cat ) { ?>
<li id="cat-<?php echo $cat->term_id; ?>"><a class="<?php echo $cat->slug; ?> ajax" onclick="cat_ajax_get(\'<?php echo $cat->term_id; ?>\');" href="#"><?php echo $cat->name; ?></a></li>
<?php } ?>
</ul>
其中,单击类别时调用jQuery ajax函数,并以函数的名称将cat ID传递给jQuery。
html div占位符,您的帖子将通过ajax加载:
<div id="loading-animation" style="display: none;"><img src="<?php echo admin_url ( \'images/loading-publish.gif\' ); ?>"/></div>
<div id="category-post-content"></div>
通过菜单项中的onclick处理程序调用jQuery函数:
<script>
function cat_ajax_get(catID) {
jQuery("a.ajax").removeClass("current");
jQuery("a.ajax").addClass("current"); //adds class current to the category menu item being displayed so you can style it with css
jQuery("#loading-animation").show();
var ajaxurl = \'<?php echo admin_url( \'admin-ajax.php\' ); //must echo it ?>\';
jQuery.ajax({
type: \'POST\',
url: ajaxurl,
data: {"action": "load-filter", cat: catID },
success: function(response) {
jQuery("#category-post-content").html(response);
jQuery("#loading-animation").hide();
return false;
}
});
}
</script>
WordPress PHP函数返回所选类别中的帖子。
add_action( \'wp_ajax_nopriv_load-filter\', \'prefix_load_cat_posts\' );
add_action( \'wp_ajax_load-filter\', \'prefix_load_cat_posts\' );
function prefix_load_cat_posts () {
$cat_id = $_POST[ \'cat\' ];
$args = array (
\'cat\' => $cat_id,
\'posts_per_page\' => 10,
\'order\' => \'DESC\'
);
$posts = get_posts( $args );
ob_start ();
foreach ( $posts as $post ) {
setup_postdata( $post ); ?>
<div id="post-<?php echo $post->ID; ?> <?php post_class(); ?>">
<h1 class="posttitle"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h1>
<div id="post-content">
<?php the_excerpt(); ?>
</div>
</div>
<?php } wp_reset_postdata();
$response = ob_get_contents();
ob_end_clean();
echo $response;
die(1);
}
我们正在使用输出缓冲,这有助于防止WordPress Ajax有时会出现的功能故障。
