Function Component: Create

The component is defined as a function named Create.

submitHandler Function

• Purpose: This function handles the form submission.
• Parameters: Takes an event object as a parameter.
• Functionality:
  • Prevents the default form submission behavior using event.preventDefault().
  • Retrieves the values from the form fields (title, body, and author).
  • Constructs a data object with these values.
  • Makes a POST request to a specified URL using Axios, sending the data object.
  • If the request is successful, logs the response and resets the form fields.
  • If the request fails, logs the error.

JSX Structure

The component returns a JSX fragment (<>...</>) containing the following elements:

• Container Div: A div with the class container to contain the form.
• Row Div: A div with the class row to structure the layout.
• Column Div: A div with classes col-lg-8, col-md-10, and mx-auto to center the form within the container.
• Paragraph: A paragraph element with the text "Create a post......?".
• Form: A form element with:
  • Class sentMessage
  • ID contactForm
  • onSubmit handler set to submitHandler

Form Fields

The form contains three input fields and a submit button:

1. Title Input:

   • Type: text
   • Class: form-control
   • Placeholder: "Title"
   • ID: title
   • Required: true
   • Name: title

2. Body Textarea:

   • Class: form-control
   • Placeholder: "Body"
   • ID: body
   • Name: body

3. Author Input:

   • Type: text
   • Class: form-control
   • Placeholder: "Author"
   • ID: author
   • Required: true
   • Name: author

4. Submit Button:

   • Type: submit
   • Class: btn btn-primary
   • ID: sendMessageButton
   • Text: "Send"

Summary

This React component provides a form for creating a post with a title, body, and author. When the form is submitted, the submitHandler function collects the input data and sends it to a specified URL using Axios. If the submission is successful, the form is reset; otherwise, any errors are logged to the console.
