Foreach循环位置无法正常工作

Question

我正在尝试列出已存储在mysql数据库中的人员的列表，但是只有第一个数据库项目的样式正确，而其他项目则不合适。我对CSS很陌生，可能在while循环或定位中犯了一个错误。

我正在使用的代码如下：

   <div id="adminsummary">

<div id="admintitel">
    <p id="admintext">Admin Overview</p>
</div>
<?php
while ($row = mysqli_fetch_array($result)) {
    $steamid = $row["steamid"];
    $xml = simplexml_load_file("http://steamcommunity.com/profiles/$steamid/?xml=1");
    if (!empty($xml)) {
        $username = $xml->steamID;
    }
    ?>

    <div id="admin">
        <img id="adminimg" src="<?php echo $steamprofile['avatarmedium']; ?>">
        <p id="adminname"><?php echo $username; ?></p>
     <!--   <p id="adminname"> SteamID: <?php echo $row["steamid"]; ?></p> -->
        <p id="adminname"> Rank: <?php if ($row["rank"] == 1) {echo "SuperAdmin";} else {echo "Admin";} ?></p>
        <hr id="hr2">
    </div>
    </div>

样式表：

#adminsummary {
    background: white;
    margin-top: 5%;
    height: 75%;
    width: 25%;
    margin-right: 5%;
    float:right;
    border-radius: 25px;
    box-shadow: 10px 10px 77px -6px rgba(0,0,0,0.59);
}

#admintitel{
    background: #343a40;
    border-top-left-radius: 25px;
    border-top-right-radius: 25px;


}

#admintext{
    color: white;
    font-family: sans-serif;
    font-weight: bold;
    text-align: center;
    padding: 25px;

}


#adminimg {

    border-radius: 25px;
    float: left;
    margin-left: 25px;
}


#hr2 {
    display: block;
    margin-top: 25px;
    margin-bottom: 0.5em;
    margin-left: auto;
    margin-right: auto;
    border-style: inset;
    border-width: 1px;
}

#adminname {
    text-align: left;
    font-weight: bold;
    margin-left: 25%;
    font-family: sans-serif;
}

感谢您抽出宝贵的时间来帮助我

Answer 1

尝试在divs循环内的p和while中将类而不是id放置。

ID在CSS中是唯一的，这说明了为什么设置第一行的样式，而不是其他行的样式。

Answer 2

如果您修改HTML并删除循环中的ID，则可以将类与子/兄弟选择器组合使用，以更简洁的方式分配样式

<!-- these IDs are OK as they are unique ( presumably ) -->
<div id="adminsummary">

    <div id="admintitel">
        <p id="admintext">Admin Overview</p>
    </div>

    <?php

        while ($row = mysqli_fetch_array($result)) {
            $steamid = $row["steamid"];
            $xml = simplexml_load_file("http://steamcommunity.com/profiles/$steamid/?xml=1");

            if (!empty($xml)) {
                $username = $xml->steamID;
            }

    ?>

    <!-- use classes &/or sibling selectors for cleaner html ~ no duplicate IDs though -->
    <div class="admin">
        <img src="<?php echo $steamprofile['avatarmedium']; ?>">
        <p><?php echo $username; ?></p>
        <p> Rank: <?php if ($row["rank"] == 1) {echo "SuperAdmin";} else {echo "Admin";} ?></p>
        <hr />
    </div>


    <?php
        }//close loop
    ?>

</div>

经过轻微修改的CSS，使用子选择器在.admin代码块内分配样式

#adminsummary {
    background: white;
    margin-top: 5%;
    height: 75%;
    width: 25%;
    margin-right: 5%;
    float:right;
    border-radius: 25px;
    box-shadow: 10px 10px 77px -6px rgba(0,0,0,0.59);
}
#admintitel{
    background: #343a40;
    border-top-left-radius: 25px;
    border-top-right-radius: 25px;
}
#admintext{
    color: white;
    font-family: sans-serif;
    font-weight: bold;
    text-align: center;
    padding: 25px;
}


#adminsummary .admin img {
    border-radius: 25px;
    float: left;
    margin-left: 25px;
}

#adminsummary .admin hr {
    display: block;
    margin-top: 25px;
    margin-bottom: 0.5em;
    margin-left: auto;
    margin-right: auto;
    border-style: inset;
    border-width: 1px;
}
#adminsummary .admin p {
    text-align: left;
    font-weight: bold;
    margin-left: 25%;
    font-family: sans-serif;
}
