Add or remove input fields dynamically in PHP using jQuery

Today we’ll show you how to add or remove input fields dynamically in PHP using jQuery. Previously we have implemented the same type of the functionality to add or remove input fields dynamically in React.

In this article, we will see an example to add multiple fields with the remove button and how to get field value after form submission using PHP. Also we can remove the added fields by clicking on the remove link.

1. Create HTML form

Let’s create a HTML form with a single input field and Add More button.

Also use the following style to design the page.

2. Add jQuery library

We have to add the following jQuery library in the head section of the page.

3. Add jQuery script

Let’s write a code to add or remove elements from the DOM using jQuery.

In the above script, we have set a maximum limit of input fields that indicates the user can add maximum 5 input fields but you can change it as per your requirements.

When the user clicks on the Add More button then a new input field with remove link will be added until the count reaches maximum limit. Similarly when the user clicks on the Remove link, the relevant input field will be removed.

4. Get values using PHP

After the form submission, we will get the value of input fields in the type of the array like below.

We have also shown you the logic to loop through each item where you can insert it into the database table.

5. Output

Combine all codes together and see how it works.

index.php
