Javascript – How to set MUI input value inside loop with array value in react js?

I have created the React js demo using React MUI. I have made a separate component for each input called InputText.js and used this for each text box. My issue is when I used this component for any single information then it’s working fine but I have prepared one array using useState for education and I want to set each education in a separate input box using a loop in JSX but it is not works.

I have managed the input validation using react-hook-form with controller method.

Please check all my code and help me to fix this issue

components/InputText.js

import * as React from "react";
import { useState } from "react";
import TextField from "@mui/material/TextField";
import { PropTypes } from "prop-types";
import { Controller } from "react-hook-form";

const InputText = React.forwardRef(({ control, ...rest }, ref) => {

  const [textValue, setTextValue] = useState("");
  const onTextChange = (e, field) => {
    setTextValue(e.target.value);
    return rest.onChange(e);
  };
  return (
    <Controller
      name={rest.name}
      rules={rest.rules}
      control={control}
      render={({ field }) => (
        <TextField
          fullWidth
          onChange={e => {
            onTextChange(e, field);
          }} 
          label={rest.label}
          type={rest.type}
          value={textValue}
          helperText={rest.helperText}
          disabled={rest.disabled}

          ref={ref}
          //onChange={onTextChange}
        />
      )}

    Here is the answer!

    <InputText
  label={"Education"} 
  name={`edu[${index}].education`}
  onChange={onInputChange}
  control={control}
  value={row.education}
/>

    I have used the name as name={edu[${index}].education} and it works perfectly

    The issue you’re facing seems to be related to how you’re handling the state for each input field using the textValue state in the InputText component. Since you’re using an array of education objects and want to display each education in a separate input box using a loop, you need to manage the state of each input field individually.

    Here’s a modified version of your InputText component that is better suited for handling input fields within a loop and array data:

    import * as React from "react";
import TextField from "@mui/material/TextField";
import { PropTypes } from "prop-types";
import { Controller } from "react-hook-form";

const InputText = React.forwardRef(({ control, ...rest }, ref) => {

  return (
    <Controller
      name={rest.name}
      rules={rest.rules}
      control={control}
      render={({ field }) => (
        <TextField
          fullWidth
          onChange={field.onChange}
          label={rest.label}
          type={rest.type}
          value={field.value}
          helperText={rest.helperText}
          disabled={rest.disabled}
          {...field}
          ref={ref}
        />
      )}
    />
  );
});

InputText.defaultProps = {
  type: "text",
  name: "",
  label: "Field",
  value: "",
  disabled: false,
};
InputText.propTypes = {
  label: PropTypes.string,
  value: PropTypes.string,
};

export default InputText;

    Now, in the component where you’re rendering the education inputs, you can map over the array of education objects and render separate input fields for each education:

    import React from "react";
import { useForm, Controller } from "react-hook-form";
import InputText from "./InputText";

const EducationForm = () => {
  const { control, handleSubmit } = useForm();
  const [educations, setEducations] = React.useState([
    { id: 1, title: "Education 1" },
    { id: 2, title: "Education 2" },
    // ... other education objects
  ]);

  const onSubmit = (data) => {
    console.log(data);
  };

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      {educations.map((education) => (
        <Controller
          key={education.id}
          name={`education_${education.id}`} // Use a unique name for each input
          control={control}
          defaultValue={education.title} // Set initial value
          render={({ field }) => (
            <InputText
              control={control}
              {...field}
              label={`Education ${education.id}`}
              rules={{ required: true }} // Add your validation rules
            />
          )}
        />
      ))}
      <button type="submit">Submit</button>
    </form>
  );
};

export default EducationForm;

    This way, you’re mapping over the educations array and rendering separate input fields for each education object. Each input field has a unique name (education_${education.id}) to distinguish them and the defaultValue is set based on the education title. The state management for each input field is now handled by the react-hook-form library through the Controller component.
