How to easily complete encoding conversion tasks in dedecms

In order to easily complete the encoding conversion task in DedeCMS, first we need to understand the encoding structure and related files of DedeCMS. DedeCMS is a PHP-based content management system that uses UTF-8 encoding by default. But sometimes we need to convert website content to other encoding formats, such as GB2312, etc. Next, I will introduce how to implement the encoding conversion task in DedeCMS and provide specific code examples.

First of all, we can find the charset.func.php file in the include directory of DedeCMS. This file is a function library used to handle character encoding conversion. We can add custom encoding conversion functions in this file to meet specific needs.

Suppose we need to convert the website content from UTF-8 encoding to GB2312 encoding, we can add the following code to the charset.func.php file:

function utf8_to_gb2312($str) {
    return iconv('UTF-8', 'GB2312', $str);
}

Next , we need to call this function in the DedeCMS template file to achieve content encoding conversion. Suppose we want to convert the article title and content into GB2312 encoding in the article page. We can add the following code to the article template file:

$title = $article['title'];
$content = $article['content'];

$title_gb2312 = utf8_to_gb2312($title);
$content_gb2312 = utf8_to_gb2312($content);

echo $title_gb2312;
echo $content_gb2312;

Through the above code, the title and content can be converted into the article page. Convert to GB2312 encoding function.

In addition, if we need to convert the data submitted by the user from GB2312 encoding to UTF-8 encoding and store it in the database, we can use the following code:

$username = $_POST['username'];
$content = $_POST['content'];

$username_utf8 = iconv('GB2312', 'UTF-8', $username);
$content_utf8 = iconv('GB2312', 'UTF-8', $content);

// 将数据插入数据库
$sql = "INSERT INTO table_name (username, content) VALUES ('$username_utf8', '$content_utf8')";

Through the above code, we It can convert user-submitted data from GB2312 encoding to UTF-8 encoding and store it in the database.

In general, by customizing the encoding conversion function in the charset.func.php file of DedeCMS and calling these functions in the template file, we can easily complete it in DedeCMS encoding conversion task. This method is not only convenient, but also has a certain degree of flexibility and can meet various needs.
