我发布了我编辑的代码，并且有新的错误w / c我不明白

注意：未定义的索引：product_brand in   第152行的C：\ xampp \ htdocs \ JGMarketing \ Admin_Area \ insert_product.php

注意：未定义的索引：product_price in   第153行的C：\ xampp \ htdocs \ JGMarketing \ Admin_Area \ _ insert_product.php

  x="hello"
  commands.getoutput("echo x | cat >> /mytxt.txt".format(x))

Answer 1

您将提交按钮名称定义为＆＃34; insert_post＆＃34;。但是，如果条件你采取另一个名称（如果（isset（$ _ POST [＆＃39; insert_product＆＃39;]）））。更改名称。

Answer 2

您的查询错误：

 $insert_product="insert into products 
(product_cat,product_brand,product_name,product_price,product_desc,product_image,product_keywords) values('$product_cat','$product_brand','$product_name','$product_price',','$product_desc','$product_image','$product_keywords')";

插入此查询：

$insert_product="insert into products 
    (product_cat,product_brand,product_name,product_price,product_desc,product_image,product_keywords) values('$product_cat','$product_brand','$product_name','$product_price','$product_desc','$product_image','$product_keywords')";

Answer 3

尝试使用这样的...请确保正确检查数据库连接和表单操作。

if(isset($_POST['insert_post'])){

//getting text data from fields
 $product_name = $_POST['product_name'];
$product_cat = $_POST['product_cat'];
$product_brand = $_POST['product_brand'];
$product_price = $_POST['product_price'];
$product_desc = $_POST['product_desc'];
$product_keywords = $_POST['product_keywords'];


//getting image from fields
$product_image = $_FILES['product_image']['name'];
$product_image_tmp = $_FILES['product_image']['tmp_name'];

move_uploaded_file($product_image_tmp,"product_images/$product_image");

    $insert_product="insert into products (product_cat,product_brand,product_name,product_price,product_desc,product_image,product_keywords) values('$product_cat','$product_brand','$product_name','$product_price','$product_desc','$product_image','$product_keywords')";

 $insert_pro = mysqli_query($con, $insert_product);

if($insert_pro){

echo"alert('Product Has been inserted')";

echo"window.open('insert_product.php','_self')";

}

else{
    echo "Something has gone wrong";
}

    }

错误：“注意：未定义的索引”
