我一直在努力解决这个问题,虽然很接近,但我就是想不通。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>";
}
?>

我是如此接近,但我不明白如何创建驻留在我上面的 while 循环之间的“回声语句”。我的猜测是我会做一些类似于...$fieldList .= $values;
的事情,根据用户在我的下拉框中选择的项目数量,语句将根据需要增长。
