Question

我知道标题没有多说。

我正在创建一个网站，如果他们愿意，我希望人们查看一本书。此代码位于页面上的产品信息下：

      <span class='starRating'>
            <input id="rating5" type="radio" name="rating" value="5">
            <label for="rating5">5</label>
            <input id="rating4" type="radio" name="rating" value="4">
            <label for="rating4">4</label>
            <input id="rating3" type="radio" name="rating" value="3" checked>
            <label for="rating3">3</label>
            <input id="rating2" type="radio" name="rating" value="2">
            <label for="rating2">2</label>
            <input id="rating1" type="radio" name="rating" value="1">
            <label for="rating1">1</label>
      </span>
</select><br><br>
<button type='submit' onclick='comment.php'>Voeg toe</button>
<?php 
    $name = $_GET['Naam'];
    $comment = $_GET['Comment'];
    $rating = $_GET['rating'];
    if ($name != '' && $comment != '') {
    switch ($rating1) {
        case $rating = "1" :
            $ratingImg = '<img src=/nl/images1/star-on.svg>';
            break;
        case $rating = "2" :
            $ratingImg = '<img src=/nl/images1/star-on.svg><img src=/nl/images1/star-on.svg>';
            break;
        case $rating = "3" :
            $ratingImg = '<img src=/nl/images1/star-on.svg><img src=/nl/images1/star-on.svg><img src=/nl/images1/star-on.svg>';
            break;
        case $rating = "4" :
            $rating = '<img src=/nl/images1/star-on.svg><img src=/nl/images1/star-on.svg><img src=/nl/images1/star-on.svg><img src=/nl/images1/star-on.svg>';
            break;
        case $rating = "5" :
            $ratingImg = '<img src=/nl/images1/star-on.svg><img src=/nl/images1/star-on.svg><img src=/nl/images1/star-on.svg><img src=/nl/images1/star-on.svg><img src=/nl/images1/star-on.svg>';
            break;
    }
    $finalComment = "<?php 
    echo '<hr><p>Door: $name</p><p>Score: $ratingImg</p><p>$comment</p><br>';?>"
    ;

我想将人们选择的星数作为变量。我有来自here的星系。当我发送以下内容时，在我的URL栏中：...？rating = 5＆amp; ...

我可以在$ratingImg变量中获取此内容吗？如果我的问题不清楚，请说出来。

Answer 1

$name = $_GET['Naam'];
$comment = $_GET['Comment'];
$rating = $_GET['rating'];
if ($name != '' && $comment != '') {
switch ($rating1) {

更改为

$name = $_GET['Naam'];
$comment = $_GET['Comment'];
$rating = $_GET['rating'];
if ($name != '' && $comment != '') {
switch ($rating) {

您没有变量 $ rating1

Answer 2

您的开关正在调用名为$ rating1的变量，该变量未定义。它应该改为$ rating

错别选Typos是杀手。 =（

从星评系统中获取信息
