<?php if($meta_box_value5){?><?php echo $meta_box_value5; ?><?php } ?>

自定义post-type调取文章

指定栏目调取

<?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>

<?php the_title(); ?>

</a></h4>

</div>

<?php endwhile; wp_reset_query(); //重置 query 查询

} ?>

指定自定义分类调取

<?php

$args = array( ‘post_type’ => ‘products’, ‘posts_per_page’ => 8, ‘paged’ => get_query_var(‘paged’) );

$loop = new WP_Query( $args );

while ( $loop->have_posts() ) : $loop->the_post(); ?>

</div>

<?php the_title(); ?>

</a></h4>

</div>

<?php endwhile; ?>

//首页滚动banner

<?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”/>

<?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>

<?php endwhile; ?>

指定自定义类别调取

<?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=“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

category.php页面使用，使用query_posts(); WordPress的主查询函数。

<?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(); ?>

<?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>

<?php echo mb_strimwidth(strip_tags(apply_filters(‘the_excerpt’, $post->post_content)), 0, 200,“…”); ?>

</div>

</li>

<?php endwhile; wp_reset_query(); ?>

调取分类及分类下的文章

调取自定义分类及分类下的文章

<?php

$taxonomys = get_categories( array( ‘taxonomy’ => ‘products_category’ ) );

if ( !empty( $taxonomys ) ):

foreach ( $taxonomys as $taxonomy ):

<ul>

<?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’ => $taxonomy->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();

<?php the_title(); ?>

</a></li>

<?php

endwhile;

wp_reset_query(); //重置 query 查询

}

</ul>

</li>

<?php endforeach; endif; ?>

调取常规分类及分类下的文章

<?php

$categories = get_categories( array( ‘orderby’ => ‘name’, ‘parent’ => 0 ) );

if ( !empty( $categories ) ):

foreach ( $categories as $categorie ):

<ul>

<?php

$args = array( ‘orderby’ => ‘rand’, ‘showposts’ => 8, ‘cat’ => $categorie->term_id );

$query_posts = new WP_Query();

$query_posts->query( $args );

while ( $query_posts->have_posts() ): $query_posts->the_post();

<?php the_title(); ?>

</a></li>

<?php endwhile;?>

</ul>

</li>

<?php endforeach; endif; ?>

</ul>

禁止收录不必要的页面

404页面、搜索、tag页面

<?php

if ((is_404()) || (is_search()) || (is_tag())) {

echo ‘<meta name=”robots” content=”noindex, noarchive”>’;

}

插件制作选择禁止收录按钮

1	<?php if( !is_home() && get_field(‘rel_noindex’) == true ): ?><meta name=“robots” content=“noindex, noarchive”><?php endif; ?>

添加多语言版本

<?php if( !is_home() && get_field(‘rel_noindex’) == true ): ?><meta name=“robots” content=“noindex, noarchive”><?php endif; ?>

<?php $current_url = add_query_arg(array()); if($current_url){ ?>

<?php } ?>

侧边栏Sidebar.php的判断

<?php if(‘products’ == get_post_type() ) {?>

<?php } elseif(false == get_post_format()) {?>

<?php } else {?>

<?php }?>
