meta-box中tab.php应用

1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
//滑动窗口产品介绍 $meta_box_value5 = get_post_meta( $post->ID, "tab-title1", true ); $meta_box_value6 = get_post_meta( $post->ID, "tab-title2", true ); $meta_box_value7 = get_post_meta( $post->ID, "tab-title3", true ); $meta_box_value8 = get_post_meta( $post->ID, "tab-title4", true ); $meta_box_value9 = do_shortcode( wpautop( get_post_meta( $post->ID, "tab-description1", true ) ) ); $meta_box_value10 = do_shortcode( wpautop( get_post_meta( $post->ID, "tab-description2", true ) ) ); $meta_box_value11 = do_shortcode( wpautop( get_post_meta( $post->ID, "tab-description3", true ) ) ); $meta_box_value12 = do_shortcode( wpautop( get_post_meta( $post->ID, "tab-description4", true ) ) ); //其他信息 $meta_ot_value13 = get_post_meta( $post->ID, "other13", true ); $meta_ot_value14 = get_post_meta( $post->ID, "other14", true ); $meta_ot_value15 = get_post_meta( $post->ID, "other15", true ); $meta_ot_value16 = get_post_meta( $post->ID, "other16", true ); |
自定义post-type调取文章
1、指定自定义分类下的具体栏目
|
1 2 3 4 5 6 7 8 |
<?php $args = array( 'post_type' => 'homeslider', 'posts_per_page' => 7, 'tax_query' => array(array('taxonomy' => 'homeslider_category','terms' => 5))); $loop = new WP_Query( $args ); while ( $loop->have_posts() ) : $loop->the_post(); ?> <li> <a href="<?php the_post_thumbnail_url( 'one' ); ?>" class="diamond <?php echo get_post_meta( $post->ID, '_class_id', true ); ?> lightbox" data-plugin-options="{'type':'image'}"> <div class="content"> <img src="<?php the_post_thumbnail_url( 'full' ); ?>" class="img-fluid plugin-random-images" alt="<?php the_title(); ?>"/> </div> </a> </li> <?php endwhile; wp_reset_query();?> |
2、在当前自定义栏目下
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 |
<?php $args = array( 'post_type' => 'products', //自定义文章类型名称 'posts_per_page' => 8, //输出的文章数量，这个可以是缺省值，不用设置 'paged' => get_query_var('paged'), 'tax_query' => array( array( 'taxonomy' => 'products_category',//自定义分类法名称 'terms' => $term_id, //id 为 64 的分类。也可是多个分类 array(12,64) ), ) ); $my_query = new WP_Query($args); if( $my_query->have_posts() ) { while ($my_query->have_posts()) : $my_query->the_post();?> <div class="col-lg-3 col-md-4 col-sm-6"> <div class="shopping-col"> <div class="product-img"> <img src="<?php post_thumbnail_src(); ?>" alt="<?php the_title(); ?>"> <div class="product-over-box"> <a href="<?php the_permalink() ?>"><i class="fa fa-link"></i></a> </div> </div> <div class="product-info text-center"> <h4><a href="<?php the_permalink() ?>"> <?php the_title(); ?> </a></h4> </div> </div> </div> <?php endwhile; wp_reset_query(); //重置 query 查询 } ?> |
3、指定自定义分类
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
<?php $args = array( 'post_type' => 'homeslider', 'posts_per_page' => 6 ); $loop = new WP_Query( $args ); while ( $loop->have_posts() ) : $loop->the_post(); ?> <div class="item <?php echo get_post_meta( $post->ID, '_class_id', true ); ?>"> <img src="<?php echo post_thumbnail_src(); ?>" alt="<?php the_title();?>" class="slide-image"/> <div class="container"> <div class="carousel-caption text-left"> <h1><?php the_title();?></h1> <?php the_excerpt() ?> <p><a class="btn btn-lg btn-primary" href="<?php echo get_post_meta( $post->ID, '_class_url', true ); ?>" role="button">Read more</a></p> </div> </div> </div> <?php endwhile; ?> |
4、通过meta_key调取
|
1 2 3 4 5 6 7 8 |
<?php $args = array( 'post_type' => 'homeslider', 'posts_per_page' => 5, 'meta_key' => '_class_id','meta_value' =>'customer' ); $loop = new WP_Query( $args ); while ( $loop->have_posts() ) : $loop->the_post(); ?> <div class="single-product clearfix"> <div class="image"> <a href="<?php echo get_post_meta( $post->ID, '_class_url', true ); ?>"></a> <img src="<?php the_post_thumbnail_url( 'two' ); ?>" alt="<?php the_title();?>"/> </div> <a href="<?php echo get_post_meta( $post->ID, '_class_url', true ); ?>" class="title"><?php the_title();?></a> </div> <?php endwhile; ?> |
常用调取文章方法
1、category.php页面使用，使用query_posts(); WordPress的主查询函数。
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
<?php $num = rand(1, 9); //$num = 1; $cat_ID = get_query_var('cat'); query_posts( array( 'cat' => $cat_ID,'posts_per_page' => 10,'order' =>ASC, 'paged' => get_query_var('paged') ) ); if ( have_posts() ) while ( have_posts() ) : the_post(); ?> <li class="clearfix"> <div class="col-md-4"><a href="<?php the_permalink() ?>"><img src="<?php the_post_thumbnail_url( 'three' ); ?>" alt="<?php the_title(); ?>"></a></div> <div class="col-md-8"> <div class="team-details"> <h5><a href="<?php the_permalink() ?>"> <?php the_title(); ?> </a></h5> <div style="padding:10px 0 5px;">By GREENLINE / <a href="javascript:void(0);"> <i class="icn fa fa-eye"><span class="sr-only">icon</span></i> <span> <?php post_views(' ', '');?> </span> </a> / <i class="fa fa-calendar"></i> <?php the_time('d-m-y'); ?> </div> </div> <?php echo mb_strimwidth(strip_tags(apply_filters('the_excerpt', $post->post_content)), 0, 200,"..."); ?> <div><a href="<?php the_permalink() ?>">>> Read More</a></div> </div> </li> <?php endwhile; wp_reset_query(); ?> |
2、任意地方调取栏目文章
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
<?php $num = rand(1, 3); //$num = 1; query_posts( array( 'cat' => 1, 'posts_per_page' => 3 ) ); if ( have_posts() ) while ( have_posts() ) : the_post(); ?> <div class="col-sm-9 col-md-6 col-lg-4 mb-4 mb-lg-0"> <a href="<?php the_permalink(); ?>" class="text-decoration-none" data-cursor-effect-hover="plus"> <div class="card border-0"> <div class="card-img-top position-relative overlay"> <div class="position-absolute bottom-10 right-0 d-flex justify-content-end w-100 py-3 px-4 z-index-3"> <span class="text-center bg-primary text-color-light font-weight-semibold text-5-5 line-height-2 px-3 py-2"> <span class="position-relative z-index-2"> <?php the_time('d'); ?> <span class="d-block custom-font-size-1 positive-ls-2 px-1"><?php the_time('m'); ?>月</span> </span> </span> </div> <img src="<?php the_post_thumbnail_url( 'two' ); ?>" class="img-fluid" alt="<?php the_title(); ?>" /> </div> <div class="card-body py-4 px-0"> <span class="d-block text-color-grey font-weight-semibold positive-ls-2 text-2">桌木鸟发布</span> <h3 class="text-transform-none font-weight-bold text-5 text-color-hover-primary mb-2"><?php the_title(); ?></h3> <p class="mb-2"><?php echo mb_strimwidth(strip_tags(apply_filters('the_excerpt', $post->post_content)), 0, 150,"..."); ?> </p> <span class="custom-view-more d-inline-flex font-weight-medium text-color-primary"> 了解更多 <img width="27" height="27" src="<?php bloginfo('template_url'); ?>/img/demos/construction/icons/arrow-right.svg" alt="" data-icon data-plugin-options="{'onlySVG': true, 'extraClass': 'svg-fill-color-primary ms-2'}" style="width: 27px;" /> </span> </div> </div> </a> </div> <?php endwhile; wp_reset_query(); ?> |
禁止收录不必要的页面
|
1 2 3 4 5 |
<?php if ((is_404()) || (is_search()) || (is_tag())) { echo '<meta name="robots" content="noindex, noarchive">'; } ?> |
侧边栏Sidebar.php的判断
|
1 2 3 4 5 6 7 |
<?php if('products' == get_post_type() ) {?> <?php } elseif(false == get_post_format()) {?> <?php } else {?> <?php }?> |
