    Loan Repayment Calculator and Application Form [qis-subscribe] Shortcode

    The Quick Interest Slider (QIS) shortcode 'qis-subscribe' manages subscription and unsubscription of users. It verifies subscription requests, sends notifications, and updates the user's status.

    Shortcode: [qis-subscribe]

    Examples and Usage

    Basic example - Displays the subscription confirmation or error message based on the 'sub' GET parameter.

    [qis-subscribe sub=1234567890 /]

    Advanced examples

    Using the shortcode to display a message based on the 'sub' GET parameter. If the 'sub' GET parameter matches a timestamp in the 'qis_messages' option and the message has not been confirmed, it sends a notification and updates the message to confirmed. If the message is already confirmed, it displays a different message.

    [qis-subscribe sub=1234567890 notification=true /]

    Using the shortcode to display a message based on the 'unsub' GET parameter. If the 'unsub' GET parameter matches a timestamp in the 'qis_messages' option, it removes the message and displays a message confirming the unsubscription. If the message is not found, it displays a different message.

    [qis-subscribe unsub=1234567890 /]

	$auto = qis_get_stored_autoresponder(null);
	if ( isset ($_GET['sub']) ) {
		$ref = $_GET['sub'];
		foreach ($message as $key => $value ) {
			if ($ref == $value['timestamp'] && $value['confirmed'] != true) {
				if ($auto['notification']) qis_send_notification ($value);
				$message[$key]['confirmed'] = true;
				update_option('qis_messages',$message);
				return '<div class="emailresponse">'.$auto['subscribemessage'].'</div>';
			}
		}

				update_option('qis_messages',$message);
				return '<div class="emailresponse">'.$auto['unsubscribemessage'].'</div>';

    Loan Repayment Calculator and Application Form [qisprogress] Shortcode

    The Quick Interest Slider shortcode is designed to display a progress bar on a webpage. This shortcode fetches user data and displays it in a progress bar format. It checks for user input, sanitizes it, and compares it with stored values. If a match is found, it generates a progress bar with steps based on the user's progress. If no match is found, it displays a message. This shortcode also includes a form for users to input their email and reference.

    Shortcode: [qisprogress]

    Examples and Usage

    Basic example - Displays the progress of a loan application using the email and reference provided by the user.

    [qisprogress /]

    Advanced examples

    Displays the progress of a loan application using the email and reference provided by the user, with the progress steps highlighted in a specific color.

    [qisprogress highlight="#FF0000" /]

    Displays the progress of a loan application using the email and reference provided by the user, with the progress steps highlighted in a specific color and the background of the progress steps in a different color.

    [qisprogress highlight="#FF0000" background="#FFFFFF" /]

    Displays the progress of a loan application using the email and reference provided by the user, with the progress steps highlighted in a specific color, the background of the progress steps in a different color, and the rejected steps in yet another color.

    [qisprogress highlight="#FF0000" background="#FFFFFF" rejected="#000000" /]

    Please note that in the advanced examples, the colors are specified using hexadecimal color codes. You can replace these with any valid color code of your choice.
