```jsx
##### I: Importing Dependencies
Start by importing React and any necessary services:
```
import React, { Component } from 'react';
import { createCategory } from '../../services/ApiCategory';
```
#### II: Defining the Class Component
```
class CategoryFormClass extends Component {
state = {
name: '',
description: ''
};
state = {
name: '',
description: ''
};
render() {
return (
"test"
);
}
}
```
handleChange = (event) => {
this.setState({ [event.target.name]: event.target.value });
};
#### III: Exporting the Component
handleSubmit = async (event) => {
```
export default CategoryFormClass;
```
#### IV: Handling Input Changes & Submit Function
```
handleChange = (event) => {
this.setState({ [event.target.name]: event.target.value });
};
handleSubmit = (event) => {
event.preventDefault();
const { name, description } = this.state;
await createCategory({ name, description });
this.setState({ name: '', description: '' });
this.props.fetchCategories();
};
console.log(this.state);
alert(`Category Name: ${name}\nCategory Description: ${description}`);
render() {
const { name, description } = this.state
this.setState({ name: "", description: "" });
return (
<form onSubmit={this.handleSubmit}>
<input
type="text"
name="name"
value={name}
onChange={this.handleChange}
placeholder="Category Name"
/>
<input
type="text"
name="description"
value={description}
onChange={this.handleChange}
placeholder="Category Description"
/>
<button type="submit">Add Category</button>
</form>
);
}
// Call the addCategory method passed down from CategoryListClass
// this.props.addCategory({ name, description });
// API integration will be handled in the next chapter
// await createCategory({ name, description });
// this.props.fetchCategories();
};
```
```
// handleSubmit = (event) => {
// event.preventDefault();
// const { name, description } = this.state;
// console.log(this.state);
// alert(`Category Name: ${name}\nCategory Description: ${description}`);
// this.setState({ name: "", description: "" });
// // Call the addCategory method passed down from CategoryListClass
// this.props.addCategory({ name, description });
// // Call the createCategory function, which uses axios to create a new category
// createCategory({ name, description })
// .then(response => {
// console.log("Category created successfully:", response.data);
// // Optionally, you could call fetchCategories here if you want to refresh the category list
// // this.props.fetchCategories();
// })
// .catch(error => {
// console.error("There was an error creating the category:", error);
// });
// };
```
#### V: Rendering the Form

CategoryListClass.js
```jsx
#### I: Importing Dependencies
Start by importing React and any necessary services:
```
import React, { Component } from 'react';
import CategoryFormClass from './CategoryFormClass';
import { getCategories, deleteCategory, updateCategory } from '../../services/ApiCategory';
import './Category.css';

.then((response) => response.data);
};
export const updateCategory = (id, category) => {
return axios.put(`${apiUrl}/${id}`, category)
.then((response) => response.data);
};
// Example with custom headers
// export const createCategory = (category, token) => {
