Bootstrap is the most popular solution for creating beautiful, intuitive, mobile-ready UI elements. It’s easy to include the Bootstrap library for the user.

Often, many of my readers ask for Bootstrap integration code. So I decided to create the first example of Bootstrap that can interact with PHP.

Bootstrap provides built-in features for handling UI responsiveness, form validation, and more. I used the SVG icon library to display the contact form fields with appropriate icons.

The Bootstrap interface looks rich. The UI attracts people and allows them to use it easily. Also, the developer’s effort is reduced by using the Bootstrap framework.

Contact forms collect various user information such as name, message and more. There are various popular types of communication techniques.

Bootstrap supports various layout options to create more complex designs. Depending on the complexity of the interface design, Bootstrap is even more reliable.

This example uses the reboot form and classes to create a Bootstrap contact form. This makes this UI design responsive and compatible for all browsers and viewing environments.

This includes an existing contact form with vertical controls. Each control form has a predefined icon corresponding to the contact input. I downloaded the Bootstrap SVG icon library to have the icon.

In PHP, it handles the data sent to send them via email. Also, save the data in the database table if it exists. It is optional and can override the code.

Working With Forms In Php

This code uses a simple PHP mail() function to send the email. In the previous example, I added a Gmail SMTP email address. Replace the simple mail() function with one that uses PhpMailer via Gmail SMTP.

The contact form code is a small integrated application. This example contains a small code to have a Bootstrap contact form.

The file contains an HTML contact form template. The landing page provides a contact form to access this template.

This section shows the HTML code for the Bootstrap contact form. This HTML displays a field with a vertical contact form.

Once it detects an incorrect form field, it closes the form submission. Added this will add Bootstrap’s custom validation method to validate default fields.

This section is available for all examples of contact forms. But, it is important that we started it.

In this example, we have support for storing contact data in the database. But, it is possible and can be solved by coding.
