如何将数据插入到mysqli中的表中？

Question

我可以看到我在表单中输入的所有数据，但无法将其插入到表格中。

<?php
echo "u r at starting";
$product_title = $_POST["product_title"];
$product_cat = $_POST["product_cat"];
$cat = $_POST["cat"];
$product_price = $_POST["product_price"];
$product_keywords = $_POST["product_keywords"];
$product_desc = $_POST["product_desc"];

$product_img1 = $_FILES["product_img1"]["name"];
$product_img2 = $_FILES["product_img2"]["name"];
$product_img3 = $_FILES["product_img3"]["name"];

echo $product_title;
echo $product_cat;
echo $cat;
echo $product_price;
echo $product_keywords;
echo $product_desc;
echo $product_img1;
echo $product_img2;
echo $product_img3;


if(isset($_POST["abc"]))
{

$temp_name1 = $_FILES["product_img1"]["tmp_name"];
$temp_name2 = $_FILES["product_img2"]["tmp_name"];
$temp_name3 = $_FILES["product_img3"]["tmp_name"];

move_uploaded_file($temp_name1, "product_images/img1");
move_uploaded_file($temp_name2, "product_images/img2");
move_uploaded_file($temp_name3, "product_images/img3");

$insert_product = "INSERT INTO product_tab VALUES('$product_cat','$cat_id',NOW(),'$product_title','$product_img1','$product_img2','$product_img3','$product_price','$product_keywords','$product_desc')";

$run_product = mysqli_query($con,$insert_product);
echo $run_product;
if($run_product)
{

    echo "Product inserted successfully";
}
else
{
    echo "NOt inserted";
}
}
echo "end";
?>

$con 是脚本中定义的变量吗？您显示的代码没有定义 $con。
