#How to change the avatar on Discuz platform?

Discuz is a commonly used forum system. Users can set personal avatars on the forum to show their personality. On the Discuz platform, users can change their avatar by uploading pictures. The following will introduce in detail how to change the avatar on the Discuz platform and give corresponding code examples.

First, users need to log in to the Discuz platform and enter the personal center page. On the personal center page, users can see a "Modify Avatar" button. Clicking this button will jump to the Modify Avatar page.

On the modify avatar page, users can choose to upload a local image as a new avatar. Here, we can use the following code example to implement the function of users uploading avatars:

<form enctype="multipart/form-data" action="upload_avatar.php" method="post">
    <input type="file" name="avatar" accept="image/*">
    <input type="submit" value="上传头像">
</form>

In the above code, we use a form to implement the function of users uploading avatars. After the user selects a local image file, click the "Upload Avatar" button and submit the form data to the server's upload_avatar.php file for processing.

Next, in the upload_avatar.php file on the server side, we need to write corresponding code to process the avatar file uploaded by the user and save it to the specified path. The following is a simple PHP code example:

$avatar = $_FILES['avatar'];
$avatar_name = $avatar['name'];
$avatar_tmp = $avatar['tmp_name'];
$upload_dir = 'avatars/';
$upload_path = $upload_dir . $avatar_name;

if(move_uploaded_file($avatar_tmp, $upload_path)) {
    // 保存成功，更新用户头像信息
    // 这里可以调用Discuz提供的API或者数据库操作来更新用户的头像信息
    echo '头像上传成功！';
} else {
    // 保存失败
    echo '头像上传失败！';
}

In the above code, we first get the avatar file uploaded by the user, and then save it to the specified path (assumed here is the avatars directory). If the save is successful, the relevant API or database operation of Discuz can be called according to the actual situation to update the user's avatar information.

Through the above code example, users can change their avatar on the Discuz platform. Hope the above content is helpful to you!
