Question

在我添加项目的按钮中，在类别区域中，我的类别是修复我只能从数据库本身手动添加类别，我想在类别区域的下拉列表中插入新数据。

This is my php file

这是我的addproduct.php，在我的PHP代码中添加了一个产品。

addproduct.php
<?php
    include('session.php');

    $name=$_POST['name'];
    $category=$_POST['category'];
    $price=$_POST['price'];
    $supplier=$_POST['supplier'];
    $qty=$_POST['qty'];

    $fileInfo = PATHINFO($_FILES["image"]["name"]);

    if (empty($_FILES["image"]["name"])){
        $location="";
    }
    else{
        if ($fileInfo['extension'] == "jpg" OR $fileInfo['extension'] == "png") {
            $newFilename = $fileInfo['filename'] . "_" . time() . "." . $fileInfo['extension'];
            move_uploaded_file($_FILES["image"]["tmp_name"], "../upload/" . $newFilename);
            $location = "upload/" . $newFilename;
        }
        else{
            $location="";
            ?>
                <script>
                    window.alert('Photo not added. Please upload JPG or PNG photo only!');
                </script>
            <?php
        }
    }

    mysqli_query($conn,"insert into product (product_name,categoryid,product_price,product_qty,photo, supplierid) values ('$name','$category','$price','$qty','$location', '$supplier')");
    $pid=mysqli_insert_id($conn);

    mysqli_query($conn,"insert into inventory (userid, action, productid, quantity, inventory_date) values ('".$_SESSION['id']."', 'Add Product', '$pid', '$qty', NOW())");

    ?>
        <script>
            window.alert('Product added successfully!');
            window.history.back();
        </script>
    <?php
?>

这是我的addmodal.php，其中主要是我的html和css文件。

addmodal.php
<!-- Add Product -->
<div class="modal fade" id="addproduct" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
