有在淘宝、京东等商城购买过东西的用户大概都知道,在搜索产品的时候可以通过筛选产品条件细分查询,从而获得更加精确的结果(如下图)。那么在wordpress中如何实现相似的结果?下面是亘古博客分享的通过jQuery、wordpress自定义分类法实现的多重关键词筛选查询功能。
注:以下方法仅对标签页面有效,且略有问题,因此仅供参考,如果要实际运用请自行仔细调试。
一、添加自定义分类法:
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 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 |
/* 自定义分类法 */ // 增加心情 // 增加天气 // 搜索关键字 register_taxonomy add_action( 'init', 'create_mood' ); function create_mood() { $labels = array( 'name' => _x( '心情标签', '当时心情' ), 'singular_name' => _x( 'mood', 'taxonomy singular name' ), 'search_items' => __( '心情搜索' ), 'all_items' => __( '全部心情' ), 'parent_item' => __( '上级心情' ), 'parent_item_colon' => __( '上级心情:' ), 'edit_item' => __( '修改标签' ), 'update_item' => __( '更新标签' ), 'add_new_item' => __( '增加新的心情标签' ), 'new_item_name' => __( '新心情名字' ), ); register_taxonomy('mood','post',array( 'hierarchical' => false, 'labels' => $labels )); } add_action( 'init', 'create_weather' ); function create_weather() { $labels = array( 'name' => _x( '天气标签', '当时天气' ), 'singular_name' => _x( 'weather', 'taxonomy singular name' ), 'search_items' => __( '天气搜索' ), 'all_items' => __( '全部天气' ), 'parent_item' => __( '上级天气' ), 'parent_item_colon' => __( '上级天气:' ), 'edit_item' => __( '修改标签' ), 'update_item' => __( '更新标签' ), 'add_new_item' => __( '增加新的天气标签' ), 'new_item_name' => __( '新天气名字' ), ); register_taxonomy('weather','post',array( 'hierarchical' => false, 'labels' => $labels )); } // -- END ---------------------------------------- |
二、创建tag.php文件,并添加以下代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 |
<?php if (!defined('AUTH_KEY')){header('HTTP/1.0 404 Not Found');die ('请不要直接加载这个页面。谢谢!');};?> <?php get_header(); ?> <div class="box boxA"> <form action="<?php bloginfo('url'); ?>" id="searchform" method="get"> <input type="text" value="" name="s" class="sKey" autocomplete="off"> <input type="submit" value="搜索" class="sSubmit"> </form> </div> <div class="box filter"> <p class="tagfilter" id="tag" <?php if($_GET['tag']!=''){echo ' data="'.$_GET["tag"].'"';}?>><b>标签:</b> <?php $terms = get_terms("post_tag"); $count = count($terms); if ( $count > 0 ){ foreach ( $terms as $term ) { if(strtolower(urlencode($_GET['tag']))==$term->slug){ echo '<a data="'. $term->slug .'" style="border-color: orange;">' . $term->name . '</a>'; }else{ echo '<a data="'. $term->slug .'">' . $term->name . '</a>'; } } } ?> </p> <p class="tagfilter" id="mood"<?php if($_GET['mood']!=''){echo ' data="'.$_GET["mood"].'"';}?>><b>心情:</b> <?php $terms = get_terms("mood"); $count = count($terms); if ( $count > 0 ){ foreach ( $terms as $term ) { if(strtolower(urlencode($_GET['mood']))==$term->slug){ echo '<a data="'. $term->slug .'" style="border-color: orange;">' . $term->name . '</a>'; }else{ echo '<a data="'. $term->slug .'">' . $term->name . '</a>'; } } } ?></p> <p class="tagfilter" id="weather" <?php if($_GET['weather']!=''){echo ' data="'.$_GET["weather"].'"';}?>><b>天气:</b> <?php $terms = get_terms("weather"); $count = count($terms); if ( $count > 0 ){ foreach ( $terms as $term ) { if(strtolower(urlencode($_GET['weather']))==$term->slug){ echo '<a data="'. $term->slug .'" style="border-color: orange;">' . $term->name . '</a>'; }else{ echo '<a data="'. $term->slug .'">' . $term->name . '</a>'; } } } ?> </p> <button id="filterSub" class="right">查询</button> </div> <div id="indexMain" class="box"> <div class="posts"> <?php if (have_posts()) : ?> <?php while (have_posts()) : the_post(); ?> <div class="post"> <div class="title"> <div class="avatar left"><?php echo get_avatar( get_the_author_email()); ?></div> <h3><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a></h3> <div class="meta"> <span><?php the_author(); ?></span> <span><?php the_time('Y.m.d') ?></span> <span><?php the_category(' , ') ?></span> <span><?php comments_popup_link( "0 条评论", "1 条评论", "% 条评论" );?></span> <?php the_tags('<span>标签:',' , ','</span>') ?> <?php the_terms( $post->ID,'mood','<span>心情:',' , ','</span>'); ?> <?php the_terms( $post->ID,'weather','<span>天气:',' , ','</span>'); ?> </div> </div> <div class="line"></div> <div class="content"> <?php echo mb_strimwidth(strip_tags(apply_filters('the_content', $post->post_content)), 0, 500,"..."); ?> </div> </div> <?php endwhile; ?> <?php endif; ?> <div class="navigation"> </div> </div> <?php get_sidebar(); ?> </div> <?php get_footer(); ?> |
三、添加jquery代码:
代码1:需要搜索按钮
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 30 31 32 33 34 35 36 37 38 39 40 41 42 |
$('.tagfilter a').click(function() { var papaDate = $(this).parent('.tagfilter').attr('data'); $(this).parent('.tagfilter').find('a').css('borderColor', ''); if(papaDate == undefined | papaDate == "" | papaDate != $(this).attr('data')) { $(this).css('borderColor', 'orange').parent('.tagfilter').attr('data', $(this).attr('data')); } else if(papaDate == $(this).attr('data')) { $(this).css('borderColor', '').parent('.tagfilter').attr('data', ''); } else { $(this).css('borderColor', '').parent('.tagfilter').attr('data', ''); } }); $('#filterSub').click(function() { var urlNow = 'http://' + window.location.host + '/?'; var url = urlNow; var mood = $('#mood').attr('data'); var weather = $('#weather').attr('data'); var tag = $('#tag').attr('data'); if(typeof(mood) != 'undefined') { if(mood.length > 0) { url += 'mood=' + mood; } } if(typeof(weather) != 'undefined') { if(url.substr(-1) != '?') { url += '&'; } if(weather.length > 0) { url += 'weather=' + weather; } } if(typeof(tag) != 'undefined') { if(url.substr(-1) != '?') { url += '&'; } if(tag.length > 0) { url += 'tag=' + tag; } } if(urlNow != url) { window.location.href = url; } }) |
代码2:不需要搜索按钮(演示站):
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 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 |
$('.tagfilter a').click(function() { var papaDate = $(this).parent('.tagfilter').attr('data'); $(this).parent('.tagfilter').find('a').css('borderColor', ''); if(papaDate == undefined | papaDate == "" | papaDate != $(this).attr('data')) { $(this).css('borderColor', 'orange').parent('.tagfilter').attr('data', $(this).attr('data')); } else if(papaDate == $(this).attr('data')) { $(this).css('borderColor', '').parent('.tagfilter').attr('data', ''); } else { $(this).css('borderColor', '').parent('.tagfilter').attr('data', ''); } var urlNow = 'http://' + window.location.host + '/?'; var url = urlNow; var mood = $('#mood').attr('data'); var weather = $('#weather').attr('data'); var tag = $('#tag').attr('data'); if(typeof(mood) != 'undefined') { if(mood.length > 0) { url += 'mood=' + mood; } } if(typeof(weather) != 'undefined') { if(url.substr(-1) != '?') { url += '&'; } if(weather.length > 0) { url += 'weather=' + weather; } } if(typeof(tag) != 'undefined') { if(url.substr(-1) != '?') { url += '&'; } if(tag.length > 0) { url += 'tag=' + tag; } } if(urlNow != url) { window.location.href = url; } /* var bigi = $('.tagfilter').length; var arr = new Array(); var url = 'http://' + window.location.host + '/?tag='; for(var i = 0; i < bigi; i++) { if($('.tagfilter').eq(i).attr('data') != undefined & $('.tagfilter').eq(i).attr('data') != "") { if(i != 0 & url.substr(-1) != '+') { url += '+'; } url += $('.tagfilter').eq(i).attr('data'); } } window.location.href = url;*/ }) |
注:如果网站是子目录,请把代码中的http://' + window.location.host + '/?
修改为http://' + window.location.host + '/子目录名称/?
(子目录名称为自己的子目录名称)
