Detailed explanation of how PHP implements the page display function after adding products

With the popularity of the Internet, the development of various websites and applications has attracted more and more attention and favor. Among these websites and applications, e-commerce platforms can be said to occupy a very important position. In e-commerce platforms, adding products is a very important step. Today we will discuss how to implement the method in PHP to display products immediately on the page after they are added.

First of all, let’s take a look at the basic process of adding products. Generally speaking, adding products involves the following steps:

1. Enter the product management page;
2. Click the add product button to enter the add product page;
3. Enter relevant information on the Add Product page, including product name, product price, product description, etc.;
4. Click the Add button to store the product information in the database;
5. Return to the product management page.

In this process, how can the added products be displayed immediately when returning to the product management page in the last step?

Actually, this is not a problem. After successfully adding the product, we can immediately query the database for the newly added product information and display it on the product management page. Among them, we can use the mysqli extension in PHP to realize database connection and operation.

The specific steps are as follows:

1. After successfully adding the product, use the mysqli_query function to query the latest data records in the product table:

$sql = "SELECT * FROM goods ORDER BY id DESC LIMIT 1";
$result = mysqli_query($conn, $sql);
$row = mysqli_fetch_assoc($result);

Here , we used the ORDER BY and LIMIT statements to query the latest data records.

2. Display the queried product information:

echo "添加成功！<br>";
echo "商品名称：" . $row["goods_name"] . "<br>";
echo "商品价格：" . $row["goods_price"] . "<br>";
echo "商品描述：" . $row["goods_desc"] . "<br>";

Here, we use the mysqli_fetch_assoc function to convert the query results into an associative array , and uses the key name of the array element to obtain product information.

To sum up, the PHP method to realize that the page can be displayed immediately after adding products is mainly achieved by using the query operation in the mysqli extension. Through this method, we can improve the user experience of the e-commerce platform, allowing users to see the products they added immediately after adding them, thereby increasing the traffic and conversion rate of the website.
