这是我的代码。我想将从4下拉列表中选择的选项保存到mysql。当我提交表单时，从最后一个框中选择的值将保存在 mysql 表的所有行中。现在，请告诉我我该怎么办？我正在正确从数据库表中获取下拉框值，那么问题是什么？
这是你的代码。
<?php
$status = $_POST['status'];
$driver_name= $_POST['driver_name'];
$from = $_POST['date_from'];
$to = $_POST['date_to'];
$conn = mysqli_connect('localhost', 'root', '', 'punbus') or
die("Database not connected" . mysqli_error());
if(isset($_POST['sub'])) {
foreach($status as $k=>$s){
$ins = "insert into driver_status(driver_name,status,date_from,date_to) VALUES
('".$driver_name[$k]."','$s','$from','$to')";
if (mysqli_query($conn, $ins)) {
echo "added";
} else {
echo "NOT" . mysqli_error($conn);
}
}
}
$sel = 'select Driver_name from driver_master';
$query = mysqli_query($conn, $sel);
echo "<form action='driver_status.php' method='post'>";
echo "<table cellpadding=5>";
echo "<tr>";
echo "<th>Driver Name</th>";
echo "<th>Status</th>";
echo "<th>From</th>";
echo "<th>To</th>";
echo "</tr>";
while($row=mysqli_fetch_assoc($query)){
echo "<tr><td>".$row['Driver_name']
."<input type='"hidden'" name='"driver_name[]'" value='"".$row['Driver_name']."'"/></td>";
$sel1='select d_status from status';
$query1=mysqli_query($conn,$sel1);
echo "<td><select name='"status[]'">";
while($row1=mysqli_fetch_assoc($query1)){
echo "<option value='"".$row1['d_status']."'">".$row1['d_status']."</option>";
}
echo "</select></td></tr>";
}
echo "</table>";
echo '<input type="submit" name="sub" value="Update"/>';
echo "</form>";
?>
这
类似于其他文本框 $op="从客户端选择 *，其中活动=0"; $op 1=mysql_query($op(;
echo '<select name="c" id="c" style="width:160px;" required>';
while ($row = mysql_fetch_array($op1))
{
echo $s=$row["c_name"];
if($company!=$s)
{
echo '<option value="'.$row["c_name"].'">'.$row["c_name"].'</option>';
}
}
$c=$_REQUEST['c'];
$sql="insert into project c_name) values('$c')";
$sql1=mysql_query($sql);
