Question

我一直在努力想清楚这一点，虽然很接近，但我无法解决问题。我的代码如下......

 <?php
include('functions.php');
connect();
if (isset($_POST['submit'])){
    $fieldName = $_POST['fieldName'];
    foreach($fieldName AS $key=>$values){
        $fieldList .= $values;

    }
    $fieldList = implode(',', $fieldName); //comma separated list
    echo $rowList;
    $sql = mysql_query("SELECT ".$fieldList." FROM members");
    $row = mysql_fetch_assoc($sql);
    echo "<table>";
    echo "<tr>";
    foreach ($row as $col => $value) {
        echo "<th>";
        echo $col;
        echo "</th>";
    }
    echo "</tr>";
    while ($row = mysql_fetch_assoc($sql)){
        echo "<tr><td>".$row['city']."</td><td>".$row['firstName']."</td><td>".$row['cellPhone']."</td></tr>";//***HOPING TO GENERATE THIS DYNAMICALLY WITH VARIABLES...MAYBE ANOTHER FOREACH???
    }
    echo "</table>";

}
?>

    <option value="cellPhone">Cell Phone</option>
</select>           
<input type="submit" name="submit" value="SUBMIT"/>
</form>
</body>

我非常接近，但我不明白如何创建位于上面的while循环之间的“echo语句”。我的猜测是，我会做类似于...... $fieldList .= $values;的事情，根据用户在下拉框中选择的项目数量，语句将根据需要增长。

我只是想通了。请在下面找到我用来生成我正在寻找的动态表列表的代码...

while ($row = mysql_fetch_assoc($sql)){
    echo "<tr>";
    foreach ($fieldName as $value){
        echo "<td>".$row[$value]."</td>";
    }
    echo "</tr>";
}

我希望这可以帮助那些尝试创建简单报告工具的人。
