从一个值中显示星星

Question

我已经遵循了这个很棒的教程，以获取"达到星星"评级系统：教程演示

这是完全有效的，我已经做了必要的将星形形式保存到MySQL表中的必要条件。现在，我想在桌子上显示带有教程的星级系统在我的桌子中注册的星值。典型的$starsvalue = 4; 然后显示4个有色星星，最后一个是空的。

目前，我不知道如何以$starsvalue的结果显示星星。任何帮助非常欢迎。

二手形式：

echo "<form id="ratingsForm" name="starsrating" method="POST">";
                echo "<div class="stars">";
                echo "<input type="radio" name="star" class="star-1" id="star-1" value="1" onclick="this.form.submit()"/>";
                echo "<label class="star-1" for="star-1">1</label>";
                echo "<input type="radio" name="star" class="star-2" id="star-2" value="2" onclick="this.form.submit()"/>";
                echo "<label class="star-2" for="star-2">2</label>";
                echo "<input type="radio" name="star" class="star-3" id="star-3" value="3" onclick="this.form.submit()"/>";
                echo "<label class="star-3" for="star-3">3</label>";
                echo "<input type="radio" name="star" class="star-4" id="star-4" value="4" onclick="this.form.submit()"/>";
                echo "<label class="star-4" for="star-4">4</label>";
                echo "<input type="radio" name="star" class="star-5" id="star-5" value="5" onclick="this.form.submit()"/>";
                echo "<label class="star-5" for="star-5">5</label>";
                echo "<span></span>";
                echo "</div>";
                echo "<div style="visibility:hidden"><Input type=submit name="choix" value="Valider"></div>";
                echo "</form>";

使用的CSS：

   body {
      padding: 50px;
    }
    form .stars {
      background: url("stars.png") repeat-x 0 0;
      width: 150px;
      margin: 0 auto;
    }
    form .stars input[type="radio"] {
      position: absolute;
      opacity: 0;
      filter: alpha(opacity=0);
    }
    form .stars input[type="radio"].star-5:checked ~ span {
      width: 100%;
    }
    form .stars input[type="radio"].star-4:checked ~ span {
      width: 80%;
    }
    form .stars input[type="radio"].star-3:checked ~ span {
      width: 60%;
    }
    form .stars input[type="radio"].star-2:checked ~ span {
      width: 40%;
    }
    form .stars input[type="radio"].star-1:checked ~ span {
      width: 20%;
    }
    form .stars label {
      display: block;
      width: 30px;
      height: 30px;
      margin: 0!important;
      padding: 0!important;
      text-indent: -999em;
      float: left;
      position: relative;
      z-index: 10;
      background: transparent!important;
      cursor: pointer;
    }
    form .stars label:hover ~ span {
      background-position: 0 -30px;
    }
    form .stars label.star-5:hover ~ span {
      width: 100% !important;
    }
    form .stars label.star-4:hover ~ span {
      width: 80% !important;
    }
    form .stars label.star-3:hover ~ span {
      width: 60% !important;
    }
    form .stars label.star-2:hover ~ span {
      width: 40% !important;
    }
    form .stars label.star-1:hover ~ span {
      width: 20% !important;
    }
    form .stars span {
      display: block;
      width: 0;
      position: relative;
      top: 0;
      left: 0;
      height: 30px;
      background: url("stars.png") repeat-x 0 -60px;
      -webkit-transition: -webkit-width 0.5s;
      -moz-transition: -moz-width 0.5s;
      -ms-transition: -ms-width 0.5s;
      -o-transition: -o-width 0.5s;
      transition: width 0.5s;
    }

*更新 *

按建议尝试raty，但我无法使星星显现。CSS和JS文件似乎在好地方。我想我不明白如何将其配置为设置"星星"图像文件夹和其他参数

我不知道我应该在raty的网页上非常常见的thoss代码吗？

$（'div'）。raty（{ 编号：function（）{ 返回$（this）.attr（'data-number'）; }}）;

我的代码：

  <link rel="stylesheet" href="./raty/lib/jquery.raty.css"/>
    <link rel="stylesheet" href="./raty/stylesheets/labs.css" media="screen" type="text/css"/>
    <script src="./raty/vendor/jquery.js"></script><script src="./raty/lib/jquery.raty.js"></script>
    <script src="./raty/javascripts/labs.js" type="text/javascript"></script>
    <div class="clearfix"></div>
<article>
    <div class="body">
        <h1>Default</h1>
        <p>You need just to have a <code>div</code> to build the Raty.</p>
        <div id="default"></div>
        <div class="highlight"><pre><span class="nt">&lt;div&gt;&lt;/div&gt;</span>
        </pre></div>
        <div class="highlight"><pre><span class="nx">$</span><span class="p">(</span><span class="s1">'div'</span><span class="p">).</span><span class="nx">raty</span><span class="p">();</span>
        </pre></div>    

Answer 1

根据教程，如果广播按钮为检查了，因此您将看到黄星。

$starsvalue=4;
echo "<form id="ratingsForm" name="starsrating" method="POST">";
echo "<div class="stars">";
for ($i = 1; $i <= 5; $i++) {
    echo "<input type="radio" name="star" class="star-$i" id="star-$i" value="$i" ";
    if ($i === $starsvalue) {
        echo " checked='checked' ";
    }
    echo "onclick="this.form.submit()"/>";
    echo "<label class="star-$i" for="star-$i">$i</label>";
}
echo "<span></span>";
echo "</div>";
echo "<div style="visibility:hidden"><Input type=submit name="choix" value="Valider"></div>";
echo "</form>";

Answer 2

这是我用raty制作的源代码。

步骤1：http：//github.com/wbotelhos/raty/archive/2.7.0.zip i下载了它，提取后，我将文件夹重命名为raty。

。

步骤2：我将HTML文件放置在此Raty文件夹的旁边。

<link href="raty/demo/stylesheets/labs.css" media="screen" rel="stylesheet" type="text/css">
<link href="raty/lib/jquery.raty.css" media="screen" rel="stylesheet" type="text/css">
<script src="raty/vendor/jquery.js"></script>
<script src="raty/lib/jquery.raty.js"></script>
<script src="raty/demo/javascripts/labs.js" type="text/javascript"></script>
<div data-number="5"></div>
<script>
$('div').raty({
    number:$(this).attr('data-number'),
    half     : true,
    path     : null,
    starHalf : 'raty/demo/images/star-half-mono.png',
    starOff  : 'raty/lib/images/star-off.png',
    starOn   : 'raty/lib/images/star-on.png'
});
</script>

也许Labs.css和labs.js并不有用，但是截至现在我只是复制了它，所以也要考虑一下。

编辑

对于选定的值假设$starvalue = 4

<script>
$('div').raty({
    number:$(this).attr('data-number'),
    half     : true,
    path     : null,
    starHalf : 'raty/demo/images/star-half-mono.png',
    starOff  : 'raty/lib/images/star-off.png',
    starOn   : 'raty/lib/images/star-on.png',
    score: <?php echo $starvalue; ?>
});
</script>
