Use PHP to develop the user reporting function in the knowledge question and answer website

With the development of the Internet, the knowledge question and answer website is becoming more and more popular. In order to ensure the order and quality of the website, the user reporting function has become an essential part. This article will introduce how to use PHP to develop the user reporting function in a knowledge question and answer website.

1. Demand analysis of user reporting function

In the knowledge question and answer website, users can report content posted by other users under the questions or answers. The implementation of the reporting function needs to meet the following requirements:

1. Users need to log in before they can use the reporting function.
2. Users can only report content posted by other users, but not content posted by themselves.
3. Users can choose the reason for reporting and fill in a supplementary explanation.
4. After the user submits a report, the system needs to record the report information and process it.

2. Development process of user reporting function

1. Login verification

First, it is necessary to determine whether the user has logged in. This can be achieved through the session mechanism. After the user successfully logs in, the user information is stored in the session. Subsequent operations can verify whether the user has logged in by judging whether the session exists.

2. Get target content information

The user reporting function is for content posted by other users, so it is necessary to obtain information about the target content. The ID of the target content can be passed to background processing via the GET or POST method.

3. Determine whether the publisher of the target content and the reporter are the same

After obtaining the target content information, you can determine whether the publisher of the target content and the reporter are the same through database query or other methods. Whether the currently logged in user is the same. If they are the same, the user is prompted not to report the content they posted; otherwise, proceed to the next step.

4. Display the report page

According to the requirements, the user needs to select the reason for the report and fill in the supplementary explanation. This can be done via HTML forms. Specific code examples are as follows:

<form action="report.php" method="post">
  <input type="hidden" name="target_id" value="<?php echo $target_id ?>">
  <label for="reason">举报原因：</label>
  <select name="reason" id="reason">
    <option value="1">垃圾信息</option>
    <option value="2">恶意攻击</option>
    <option value="3">违规内容</option>
  </select>
  <br>
  <label for="description">补充说明：</label>
  <textarea name="description" id="description" rows="5" cols="30"></textarea>
  <br>
  <input type="submit" value="提交">
</form>

5. Processing report requests

After the user clicks the submit button, the form data is passed to the background for processing. The background PHP file (such as report.php) can perform the following operations:

<?php
  // 获取表单数据
  $target_id = $_POST['target_id'];
  $reason = $_POST['reason'];
  $description = $_POST['description'];

  // 将举报信息记录到数据库
  // ...
  
  // 返回结果给用户
  echo '举报成功';
?>

In report.php, you can insert the report information into the database and give a prompt on the page that the report is successful.
