WordPress 文章多重字段筛选-www.88531.cn资享网

最近给某个客户定制一个关于数据下载的WordPress模板，需要使用erphpdown收费下载插件，其中要实现这样一个页面：多字段筛选。

效果如下：（这里只列出3项自定义字段）

筛选界面代码如下：

<div class="filters">   <div class="filter-item">   数据标价：<a href="<?php echo add_query_arg("price","all",selfURL())?>" class="<?php if(!isset($_GET['price']) || $_GET['price'] == 'all') echo 'on';?>">全部</a> <a href="<?php echo add_query_arg("price","free",selfURL())?>" class="<?php if($_GET['price'] == 'free') echo 'on';?>">免费</a> <a href="<?php echo add_query_arg("price","fee",selfURL())?>" class="<?php if($_GET['price'] == 'fee') echo 'on';?>">付费</a>   </div>   <div class="filter-item">   数据来源：<a href="<?php echo add_query_arg("from","all",selfURL())?>" class="<?php if(!isset($_GET['from']) || $_GET['from'] == 'all') echo 'on';?>">全部</a> <a href="<?php echo add_query_arg("from","data",selfURL())?>" class="<?php if($_GET['from'] == 'data') echo 'on';?>">引力数据</a> <a href="<?php echo add_query_arg("from","organization",selfURL())?>" class="<?php if($_GET['from'] == 'organization') echo 'on';?>">机构</a> <a href="<?php echo add_query_arg("from","internet",selfURL())?>" class="<?php if($_GET['from'] == 'internet') echo 'on';?>">互联网</a> <a href="<?php echo add_query_arg("from","personal",selfURL())?>" class="<?php if($_GET['from'] == 'personal') echo 'on';?>">个人</a>   </div>   <div class="filter-item">   数据大小：<a href="<?php echo add_query_arg("size","0",selfURL())?>" class="<?php if(!isset($_GET['size']) || $_GET['size'] == '0') echo 'on';?>">全部</a> <a href="<?php echo add_query_arg("size","1",selfURL())?>" class="<?php if($_GET['size'] == '1') echo 'on';?>">100M以下</a> <a href="<?php echo add_query_arg("size","2",selfURL())?>" class="<?php if($_GET['size'] == '2') echo 'on';?>">100M-500M</a> <a href="<?php echo add_query_arg("size","3",selfURL())?>" class="<?php if($_GET['size'] == '3') echo 'on';?>">500M-1G</a> <a href="<?php echo add_query_arg("size","4",selfURL())?>" class="<?php if($_GET['size'] == '4') echo 'on';?>">1G以上</a>   </div>   </div>

筛选功能部分代码如下：

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;   $metaArray = array(); //自定义字段数组by mobantu    if(isset($_GET['price'])){   if($_GET['price'] == 'free'){   $array_temp = array('key' => 'down_price', 'value'=>'0', 'compare'=>'=');   array_push($metaArray,$array_temp);   }elseif($_GET['price'] == 'fee'){   $array_temp = array('key' => 'down_price', 'value'=>'0', 'compare'=>'>');   array_push($metaArray,$array_temp);   }   }    if(isset($_GET['from'])){   $array_temp = array('key' => 'down_from', 'value'=>$_GET['from'], 'compare'=>'=');   array_push($metaArray,$array_temp);   }    if(isset($_GET['size'])){   if($_GET['size'] == '1'){   $array_temp = array('key' => 'down_size', 'value'=>'100', 'type' => 'numeric', 'compare'=>'<');    array_push($metaArray,$array_temp);   }if($_GET['size'] == '2'){   $array_temp = array('key' => 'down_size', 'value'=>array( 100, 500 ), 'type' => 'numeric', 'compare'=>'BETWEEN');    array_push($metaArray,$array_temp);   }   }       $args = array(   'order' => DESC,   'caller_get_posts' => 1,   'meta_query' => $metaArray,   'paged' => $paged   );    query_posts($args);

看了我的代码，相信你脑洞大开，妈妈再也不用担心你的多重筛选了~~

另外，之前也给另一个客户基于Mohtml主题开发了一个评分的功能，弄了一个评分筛选小工具，小工具选项：

部分代码如下，没有上面的代码方便，不过也可以参考：

$order = "DESC";   $orderby = 'date';   $meta_key = '';    if($review_order == 'review_desc'){   $orderby = 'meta_value_num';   $meta_key = 'review_'.$show_style;    }elseif($review_order == 'review_asc'){   $order = 'ASC';   $orderby = 'meta_value_num';   $meta_key = 'review_'.$show_style;    }elseif($review_order == 'date_asc'){   $order = 'ASC';   }elseif($review_order == 'random'){   $orderby = 'rand';   }    if($show_date == '7'){   $args = array(   'order' => $order,   'orderby' => $orderby,   'meta_key' => $meta_key,   'meta_query' => array(   array('key'=>'review_type','value'=>$type, 'compare'=>'IN'),   ),   'date_query' => array(   array(   'after' => '1 week ago'   )   ),   'showposts' => $limit,   'caller_get_posts' => 1   );   }elseif($show_date == '30'){   $args = array(   'order' => $order,   'orderby' => $orderby,   'meta_key' => $meta_key,   'meta_query' => array(   array('key'=>'review_type','value'=>$type, 'compare'=>'IN'),   ),   'date_query' => array(   array(   'after' => '1 month ago'   )   ),   'showposts' => $limit,   'caller_get_posts' => 1   );   }elseif($show_date == '183'){   $args = array(   'order' => $order,   'orderby' => $orderby,   'meta_key' => $meta_key,   'meta_query' => array(   array('key'=>'review_type','value'=>$type, 'compare'=>'IN'),   ),   'date_query' => array(   array(   'after' => '6 month ago'   )   ),   'showposts' => $limit,   'caller_get_posts' => 1   );   }elseif($show_date == '30'){   $args = array(   'order' => $order,   'orderby' => $orderby,   'meta_key' => $meta_key,   'meta_query' => array(   array('key'=>'review_type','value'=>$type, 'compare'=>'IN'),   ),   'date_query' => array(   array(   'after' => '1 year ago'   )   ),   'showposts' => $limit,   'caller_get_posts' => 1   );   }else{   $args = array(   'order' => $order,   'orderby' => $orderby,   'meta_key' => $meta_key,   'meta_query' => array(   array('key'=>'review_type','value'=>$type, 'compare'=>'IN'),   ),   'showposts' => $limit,   'caller_get_posts' => 1   );   }   query_posts($args);
