Description of Returned Data
The languageSwitcher() function is used to display a language switcher on a webpage. It allows users to switch between different language translations of a website.
This function takes no arguments and does not return any value. Instead, it generates and displays an HTML form with language options. When the user selects a language, the form is submitted to the same page via HTTP POST request. The function then reads the selected language from the form data and stores it in the user's session variable. If the user is logged in, the function also updates the user's language preference in the database.
Here is an example of how to use this function:
// Include the function definition
// Call the function to display the language switcher languageSwitcher();
This will output an HTML form containing flags for each available language. When the user clicks on a flag, the form will be submitted and the selected language will be stored in the session variable. The webpage will then be refreshed, and the translated content will be displayed in the selected language.
