问题是您将整个 <?php include "config.php"; if(isset($_POST['submit'])) { $target = "images/".basename($_FILES['image']['name']); $v_type = $_POST["v_type"]; $v_name = $_POST["v_name"]; $v_man = $_POST["v_man"]; $v_model = $_POST["v_model"]; $v_color = $_POST["v_color"]; $v_trans = $_POST["v_trans"]; $v_1_15_rent = $_POST["v_1_15_rent"]; $v_16_25_rent = $_POST["v_16_25_rent"]; $v_25_plus_rent = $_POST["v_25_plus_rent"]; $v_reg = $_POST["v_reg"]; $vendor_name = $_POST["vendor_name"]; $vendor_mobile = $_POST["vendor_mobile"]; $vendor_price = $_POST["vendor_price"]; $image = $_FILES["image"]["name"]; $v_id=$_GET["v_id"]; $sql = " UPDATE my_veh_ven SET v_type='$v_type', v_name='$v_name' ,v_man='$v_man' ,v_color='$v_color', v_trans='$v_trans', v_1_15_rent='$v_1_15_rent' , v_16_25_rent='$v_16_25_rent' ,v_25_plus_rent='$v_25_plus_rent' , image='$image' , v_reg='$v_reg' ,vendor_name='$vendor_name', vendor_mobile='$vendor_mobile' ,vendor_price='$vendor_price' WHERE v_id='$v_id' "; if (mysqli_query($conn, $sql)) { if(move_uploaded_file($_FILES['image']['tmp_name'], $target)) { $success = "✓ Successfully Updated"; } } else { $fail = "X Not Updated"; } } mysqli_close($conn); ?> 数组作为值传递给Value标记。

我不是100％确定如何正确处理选择中的嵌套数组，但您可以使用<optgroup>。

<option>
