Coldfusion Login Page Example

Web Development Software

When it comes to creating a login page for a website, the possibilities are endless. However, one programming language that stands out for its simplicity and efficiency is ColdFusion. In this article, I will walk you through a step-by-step example of how to create a ColdFusion login page, while also adding my own personal touches and commentary along the way.

Getting Started

First and foremost, let me start by saying that ColdFusion is a powerful scripting language that allows developers to build dynamic web applications. It combines HTML and CSS with server-side scripting, making it an ideal choice for creating interactive web pages.

To begin our example, let’s first create a new ColdFusion page (with a .cfm extension) and name it “loginpage.cfm”. This file will serve as our login page template. Within this file, we’ll need to include the necessary HTML and CSS to create the visual elements of our login page.

Building the Login Form

The first step in creating a login page is to build the login form. This form will typically include two input fields – one for the username and another for the password.

To create the form, we’ll use the <form> tag in HTML, along with the <input> tag to create the input fields. We’ll also need a submit button to send the form data to the server for processing. Here’s an example:

<form action="login.cfm" method="post">
<label for="username">Username:</label>
<input type="text" id="username" name="username">
<label for="password">Password:</label>
<input type="password" id="password" name="password">
<input type="submit" value="Login">

In the above code, we specified the action attribute of the <form> tag as “login.cfm”. This means that when the user clicks the submit button, the form data will be sent to the “login.cfm” file for processing.

Validating User Input

Once the user submits the login form, we’ll need to validate the input to ensure that the username and password are correct. This is an important step in the login process to prevent unauthorized access to the system.

In ColdFusion, we can use conditional statements and database queries to verify the user’s credentials. For example, we can use the <cfquery> tag to check if the username and password exist in our database. Here’s an example:

<cfquery datasource="mydatabase" name="user">
FROM users
WHERE username =
AND password =

In the above code, we used the <cfquery> tag to execute a database query. We specified the datasource attribute to indicate which database to connect to, and the name attribute to store the query result in a variable called “user”.

We then used the <cfqueryparam> tag to securely pass the form input (username and password) to the query. This helps protect against SQL injection attacks.

Handling Login Success and Failure

After validating the user’s credentials, we’ll need to handle the login success and failure scenarios. If the username and password are correct, we can redirect the user to a welcome page or display a success message. On the other hand, if the credentials are incorrect, we can display an error message and allow the user to try again.

In ColdFusion, we can use conditional statements and session variables to manage the login process. For example, if the login is successful, we can set a session variable called “isLoggedIn” to true and redirect the user to the welcome page. Here’s an example:

<cfif user.recordcount>
<cfset session.isLoggedIn = true>
<cflocation url="welcome.cfm">
<p>Invalid username or password. Please try again.</p>

In the above code, we used the <cfif> tag to check if the query result has any records. If it does, it means that the username and password are correct. We then set the session variable “isLoggedIn” to true and redirect the user to the welcome page using the <cflocation> tag.

If the login fails, we display an error message using the <p> tag and allow the user to try again.


Creating a ColdFusion login page is not only a functional necessity but also an opportunity to showcase your creativity and programming skills. By following the steps outlined in this article, you can build a secure and user-friendly login page for your website.

Remember, the login page is often the first point of interaction between the user and your website, so it’s essential to make a good impression. By utilizing ColdFusion’s power and flexibility, you can create a login page that not only meets your functional requirements but also leaves a lasting impression on your users.
