面子工程之文章评分功能

960grid
不用问,这又是一篇折腾文章,给文章添加了一个评分功能。之所以说是面子工程,是因为这文章评分功能不会写入到数据库,甚至按F5之后,这评分又被归零了。那么为什么要折腾呢,因为俺喜欢折腾。。。

折腾开始,首先找到你的single.php文件,在想要加入这评分功能的地方加入下面这段HTML代码:

<div id="starBg" class="star_bg">                      
    <input type="radio" id="starScore1" class="score score_1" value="1" name="score">
    <a href="#starScore1" class="star star_1" title="差"><label for="starScore1"></label></a>
    <input type="radio" id="starScore2" class="score score_2" value="2" name="score">
    <a href="#starScore2" class="star star_2" title="较差"><label for="starScore2">较差</label></a>
    <input type="radio" id="starScore3" class="score score_3" value="3" name="score">
    <a href="#starScore3" class="star star_3" title="普通"><label for="starScore3">普通</label></a>
    <input type="radio" id="starScore4" class="score score_4" value="4" name="score">
    <a href="#starScore4" class="star star_4" title="较好"><label for="starScore4">较好</label></a>
    <input type="radio" id="starScore5" class="score score_5" value="5" name="score">
    <a href="#5" class="star star_5" title="好"><label for="starScore5"></label></a>
</div>

然后就是给这货添加CSS效果,当然之前把这星星图片先上传到images文件夹下:

.star_bg {
    width: 120px; height: 20px;
    background: url(images/star.png) repeat-x;
    position: relative;
    overflow: hidden;
}
.star {
    height: 100%; width: 24px;
    line-height: 6em;
    position: absolute;
    z-index: 3;
}
.star:hover {    
    background: url(images/star.png) repeat-x 0 -20px!important;
    left: 0; z-index: 2;
}
.star_1 { left: 0; }
.star_2 { left: 24px; }
.star_3 { left: 48px; }
.star_4 { left: 72px; }
.star_5 { left: 96px; }
.star_1:hover { width: 24px; }
.star_2:hover { width: 48px; }
.star_3:hover { width: 72px; }
.star_4:hover { width: 96px; }
.star_5:hover { width: 120px; }

label {
    display: block; _display:inline;
    height: 100%; width: 100%;
    cursor: pointer;
}

/* 幕后的英雄,单选按钮 */
.score { position: absolute; clip: rect(0 0 0 0); }
.score:checked + .star {    
    background: url(images/star.png) repeat-x 0 -20px;
    left: 0; z-index: 1;
}
.score_1:checked ~ .star_1 { width: 24px; }
.score_2:checked ~ .star_2 { width: 48px; }
.score_3:checked ~ .star_3 { width: 72px; }
.score_4:checked ~ .star_4 { width: 96px; }
.score_5:checked ~ .star_5 { width: 120px; }

.star_bg:hover .star {  background-image: none; }

/* for IE6-IE8 JS 交互 */
.star_checked {    
    background: url(images/star.png) repeat-x 0 -20px;
    left: 0; z-index: 1;
}
