रुक मत, थक मत, चलना है,
अंधेरों से भी लड़ना है।
जो गिरकर फिर संभल गया,
उसी को आगे बढ़ना है।
ना सोच कि राह कठिन है,
ना मान कि किस्मत कमज़ोर है,
जिसके इरादे लोहे जैसे,
उसके आगे हर शोर है।
तू आग है, तू शक्ति है,
तू खुद अपनी भक्ति है,
दुनिया तुझे क्या रोकेगी,
जब तेरी सोच ही मुक्त है।
हार नहीं बस एक सबक है,
जीत तेरा अधिकार है,
जो खुद पे विश्वास रखे,
उसका ही संसार है।
उठ, जाग, और साबित कर,
तू किस मिट्टी का बना है,
जो आज खड़ा है डर के आगे,
कल वही इतिहास बना है।
The code can be a little challenging to understand at first, but feel free to ask if you don't understand any part.

How to use it:
- Log in to the Wapka Dashboard (https://web.wapka.org/dashboard);
- Select your website from the "Your services" list;
- Now create a new page called "login" (Basic Function > New Page) - you can skip this step if you already have a login page and want to use it.
- Now open the login page we created and go to Advanced function > Script, and finally paste the following Lua code into the textarea:
Code: Select all
if (env.userid ~= 0) then -- Check if the user is already logged in
url.redirect("/") -- If yes, redirect to the main page
end
if (req.method == "POST") then -- Checks if the login form has been submitted
error_message = nil -- Starts error message as null
username = req.post.username -- Gets the username from the POST request
password = req.post.password -- Gets the password from the POST request
continue = req.get.continue -- Useful if the user came from another page
if continue == nil then continue = "/" end -- Checks if a continue URL has been defined, if not, it is defined as the home page
if (username == "" and password == "") then -- Checks if the username and password are empty
error_message = "You must enter your username and password."
elseif (username == "") then -- Checks if username is empty
error_message = "You must enter your username."
elseif (password == "") then -- Checks if password is empty
error_message = "You must enter your password."
else -- Continue with login if username and password have been filled in
local param = { -- Sets the parameters for the API login method
username = username,
password = password
}
local is_ok, login, info, error_login = api.user_login(param)
if (is_ok) then -- Username and password are correct and login was successful
url.redirect(continue) -- Redirects to the destination defined in continue
else -- An error occurred while trying to login
error_message = error_login -- defines the error message as the one received in the login method
end
end
if (error_message) then -- Checks if any errors occurred and sets an error message div to display on the page
html_error = [=[<div class="error-message">%s</div>]=]
error_message = string.format(html_error, error_message)
end
end
local html_code = [=[
<h2>Log-in to your account</h2>
