The second-hand recycling website developed by PHP realizes the function of user customized needs

As people become more aware of environmental protection, the second-hand recycling market is gradually emerging. In order to make it easier for people to recycle items they no longer need, I developed a second-hand recycling website based on PHP, and added user customization functions to it to meet the personalized needs of users.

First, I used PHP's MVC architecture (Model-View-Controller) to build the website. This architecture can effectively separate the logic of the website from the interface and improve the maintainability and scalability of the code.

Next, I defined a model called Item to represent the items that the user wants to recycle. The Item model contains the attributes of the item, such as name, description, price, etc. In the database, I created a table called items to store the data for the Item model.

In the controller part, I first process the item information submitted by the user and ensure the legality of the input through verification. Then, save this information to the database.

The following is a sample code that shows how I process and verify the item information submitted by the user in the controller:

<?php

class ItemController {
    public function create() {
        // 处理用户提交的物品信息
        $name = $_POST['name'];
        $description = $_POST['description'];
        $price = $_POST['price'];

        // 验证输入的合法性
        if (empty($name) || empty($description) || empty($price)) {
            // 如果有任何一个字段为空，返回错误信息给用户
            echo "请填写完整的物品信息";
            return;
        }

        // 将物品信息保存到数据库中
        $item = new Item($name, $description, $price);
        $item->save();

        // 返回成功信息给用户
        echo "物品发布成功";
    }
}

In the view section, I provide a form interface for the user, Allow them to enter information about the item. After the user completes filling in, click the submit button to submit the form data to the above controller for processing.

The following is a sample code that shows how I create a form interface in the view:

<form action="/item/create" method="post">
    <input type="text" name="name" placeholder="物品名称">
    <textarea name="description" placeholder="物品描述"></textarea>
    <input type="text" name="price" placeholder="物品价格">
    <input type="submit" value="提交">
</form>

Through the above code example, users can fill in the name, description, price and other information of the item themselves, and submit it to the server. The server will verify the validity of the user's input and save the information to the database. Finally, the server will return corresponding information to the user, prompting them whether the operation was successful or not.

In summary, the second-hand recycling website I developed based on PHP can realize user customization requirements, allowing users to input item information by themselves and save it to the database. This personalized function can improve the user experience and also meets the requirements of current environmental awareness. I hope this website can provide a more convenient and efficient platform for people's second-hand recycling behavior.
