将foreach划分为多个div

Question

我有这个输出10个链接的函数，我想将链接分成两个div，但我认为当我调用函数时echo会丢失。

这就是我所拥有的：

            function wpb_list_child_pages() { 

            $args = array(
            'sort_order' => 'asc',
            'sort_column' => 'post_title',
            'hierarchical' => 1,
            'meta_value' => '',
            'child_of' => 108,
            'parent' => -1,
            'exclude_tree' => '',
            'offset' => 0,
            'post_type' => 'page',
            'post_status' => 'publish'
            ); 
            $pages = get_pages($args); 


            if ( $pages) 
            {   
            $links = '';
            $counter = 1;
            foreach($pages as $page):

            $links .= '<ul> <li> <a href=" ' .  get_page_link( $page->ID ) . '"> ' .$page->post_title . ' </a> </li></ul>';
            $counter++; // increment the counter variable for each loop
            endforeach; 

            return $links;

            }

            }

这就是我试图做的原因：

            function wpb_list_child_pages() { 

            $args = array(
            'sort_order' => 'asc',
            'sort_column' => 'post_title',
            'hierarchical' => 1,
            'meta_value' => '',
            'child_of' => 108,
            'parent' => -1,
            'exclude_tree' => '',
            'offset' => 0,
            'post_type' => 'page',
            'post_status' => 'publish'
            ); 
            $pages = get_pages($args); 


            if ( $pages) 
            {   
            $links = '';
            $counter = 1;
            foreach($pages as $page):
            if($counter == 1) {
            echo "<div class='left_class'>"; // open left div
            }
            $links .= '<ul> <li> <a href=" ' .  get_page_link( $page->ID ) . '"> ' .$page->post_title . ' </a> </li></ul>';
            //var_dump ($links);
            if($counter==5){
            echo "</div>"; //close left div
            echo "<div class='right_class'>"; // open right div
            }

            if($counter==10){
            echo "</div>"; //close right div
            }
            $counter++; // increment the counter variable for each loop
            endforeach; 

            return $links;

            }                               
            }

这就是我调用函数的方法

 echo '<div class="section-1">'.wpb_list_child_pages().'</div>';

您的脚本似乎在输出之前收集变量中的链接。你的（缩进的）示例应该如下所示：

        function wpb_list_child_pages() { 

        $args = array(
        'sort_order' => 'asc',
        'sort_column' => 'post_title',
        'hierarchical' => 1,
        'meta_value' => '',
        'child_of' => 108,
        'parent' => -1,
        'exclude_tree' => '',
        'offset' => 0,
        'post_type' => 'page',
        'post_status' => 'publish'
        ); 
        $pages = get_pages($args); 


        if ( $pages) 
        {   
        $links = '';
        $counter = 1;
        foreach($pages as $page):
        if($counter == 1) {
        $links .= "<div class='left_class'>"; // open left div
        }
        $links .= '<ul> <li> <a href=" ' .  get_page_link( $page->ID ) . '"> ' .$page->post_title . ' </a> </li></ul>';
        //var_dump ($links);
        if($counter==5){
        $links .= "</div>"; //close left div
        $links .= "<div class='right_class'>"; // open right div
        }

        if($counter==10){
        $links .= "</div>"; //close right div
        }
        $counter++; // increment the counter variable for each loop
        endforeach; 

        return $links;

        }                               
        }

所以，出现错误的是你在回显链接之前回显了所有（开启和关闭）标签。
