PHP Codeigniter 3 - Create Dynamic Tree View using Bootstrap Treeview JS

In this step, we are going to learn about how to create a dynamic tree view. We will use PHP Codeigniter 3 and Bootstrap Treeview JS to do this. In the below example, we will use Bootstrap Treeview JS so that we can build the dynamic tree structure in Codeigniter 3.

For our category tree or many things, we need to create a dynamic tree structure in our application. If we are developing our application using the Codeigniter framework, it will be easy for us to build the example of dynamic treeview.

For this, we will first create a new table named "item" and specify many columns like name, id, and parent_id. After that, the Codeigniter route will be created. Now we will create a new controller as "ItemController" and then create a new blade file as items.php. The step by step process to create a dynamic tree view is described as follows:

Step 1:

In this step, we are going to Create an Item Table. We will use our database and create a new table named "item". We will create it by using the SQL query, which is described as follows:

item table:

When we successfully create the table, we need to add dummy records. So we will add some records.

Step 2:

In this step, we are going to Create Route. We will create this for Ajax and View method. In this, we will use our routes.php file and then we will put the following code into that file:

application/config/routes.php

Step 3:

In this step, we are going to Create a Controller. We will create a new controller as "ItemController." We will create this with getItem(), index(), and membersTree() methods. Now we will use that file and then add the following code into it:

application/controllers/ItemController.php

Step 4:

In this step, we are going to Create View File. We will create a view file named items.php. For dynamic tree view, we will use that file and write the below code into it:

application/views/items.php

Now our above code is ready, and we can run it. When we run this, the following output will be generated:
