React Native Insert Text Input Data To MySQL Server Android iOS Tutorial

admin July 3, 2017 July 3, 2017React Native

How to Insert Text Input Data – store multiple TextInput component entered data to online PHP MySQL database server using Fetch API and Show server response inside app using Alert message after successfully inserted record.

Inserting data from React Native application to MySQL database is a very important task to every developer because without submitting data from app there is no dynamic activity in project. So in this tutorial we would going to create a react native application which would stores the Text Input entered value into MySQL database and after successfully inserting the record it would show us the response conformation message coming from server into Alert message. So let’s get started 🙂 .

Contents in this project Insert Text Input Data To MySQL Server :

1. Create a database + Table on your online hosting server.

Create a database on your MySQL server, then Create a fresh table inside the database. The table name should be UserInfoTable . Add 4 columns inside the table id, name, email, phone_number .

2. Create PHP script to insert received data from React Native application into MySQL database.

Create 2 PHP files DBConfig.php and submit_user_info.php .

DBConfig.php : This file contains the MySQL database hostname, database name, database password and database username.

submit_user_info.php : This file receive the send record from application and insert that received data into MySQL database.

Code for DBConfig.php file :

<?php

//Define your host here.
$HostName = "localhost";

//Define your database name here.
$DatabaseName = "id2070055_reactnativedb";

//Define your database username here.
$HostUser = "id2070055_reactnativedb_user";

//Define your database password here.
$HostPass = "1234567890";

?>

<?php

//Define your host here.

$HostName = "localhost";

//Define your database name here.

$DatabaseName = "id2070055_reactnativedb";

//Define your database username here.

$HostUser = "id2070055_reactnativedb_user";

//Define your database password here.

$HostPass = "1234567890";

Code for submit_user_info.php file :

<?php

// Importing DBConfig.php file.
include 'DBConfig.php';

// Creating connection.
 $con = mysqli_connect($HostName,$HostUser,$HostPass,$DatabaseName);

 // Getting the received JSON into $json variable.
 $json = file_get_contents('php://input');
 
 // decoding the received JSON and store into $obj variable.
 $obj = json_decode($json,true);

 // Populate name from JSON $obj array and store into $name.
$name = $obj['name'];

// Populate email from JSON $obj array and store into $email.
$email = $obj['email'];

// Populate phone number from JSON $obj array and store into $phone_number.
$phone_number = $obj['phone_number'];
 
 // Creating SQL query and insert the record into MySQL database table.
$Sql_Query = "insert into UserInfoTable (name,email,phone_number) values ('$name','$email','$phone_number')";
 

 if(mysqli_query($con,$Sql_Query)){
 
 // If the record inserted successfully then show the message.
$MSG = 'Data Inserted Successfully into MySQL Database' ;

// Converting the message into JSON format.
$json = json_encode($MSG);

// Echo the message.
 echo $json ;
 
 }
 else{
 
 echo 'Try Again';
 
 }
 mysqli_close($con);
?>

<?php

// Importing DBConfig.php file.

include 'DBConfig.php';

// Creating connection.

$con = mysqli_connect($HostName,$HostUser,$HostPass,$DatabaseName);

// Getting the received JSON into $json variable.

$json = file_get_contents('php://input');

// decoding the received JSON and store into $obj variable.

$obj = json_decode($json,true);

// Populate name from JSON $obj array and store into $name.

$name = $obj['name'];

// Populate email from JSON $obj array and store into $email.

$email = $obj['email'];

// Populate phone number from JSON $obj array and store into $phone_number.

$phone_number = $obj['phone_number'];

// Creating SQL query and insert the record into MySQL database table.

$Sql_Query = "insert into UserInfoTable (name,email,phone_number) values ('$name','$email','$phone_number')";

if(mysqli_query($con,$Sql_Query)){

// If the record inserted successfully then show the message.

$MSG = 'Data Inserted Successfully into MySQL Database' ;

// Converting the message into JSON format.

$json = json_encode($MSG);

// Echo the message.

echo $json ;

}

else{

echo 'Try Again';

}

mysqli_close($con);

3. Start a fresh React Native project. If you don’t know how then read my this tutorial.

4. Add AppRegistry, StyleSheet, TextInput, View, Alert, Button component inside the import block.

import React, { Component } from 'react';
 
import { AppRegistry, StyleSheet, TextInput, View, Alert, Button } from 'react-native';

import React, { Component } from 'react';

import { AppRegistry, StyleSheet, TextInput, View, Alert, Button } from 'react-native';

5. Create constructor.

Create a constructor in your Main Class with props parameter. Now declare three variables TextInputName: ‘ ‘, TextInputEmail: ‘ ‘ and TextInputPhoneNumber: ‘ ‘ with empty values using this.state.

constructor(props) {
 
    super(props)
 
    this.state = {
 
      TextInputName: '',
      TextInputEmail: '',
      TextInputPhoneNumber: ''
 
    }
 
  }

constructor(props) {

super(props)

this.state = {

TextInputName: '',

TextInputEmail: '',

TextInputPhoneNumber: ''

}

6. Create function named as InsertDataToServer() to send the Text Input data on server.

InsertDataToServer = () =>{

 
 const { TextInputName }  = this.state ;
 const { TextInputEmail }  = this.state ;
 const { TextInputPhoneNumber }  = this.state ;

fetch('https://reactnativecode.000webhostapp.com/submit_user_info.php', {
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({

    name: TextInputName,

    email: TextInputEmail,

    phone_number: TextInputPhoneNumber

  })

}).then((response) => response.json())
      .then((responseJson) => {

// Showing response message coming from server after inserting records.
        Alert.alert(responseJson);

      }).catch((error) => {
        console.error(error);
      });
 
 
  }

InsertDataToServer = () =>{

const { TextInputName } = this.state ;

const { TextInputEmail } = this.state ;

const { TextInputPhoneNumber } = this.state ;

fetch('https://reactnativecode.000webhostapp.com/submit_user_info.php', {

method: 'POST',

headers: {

'Accept': 'application/json',

'Content-Type': 'application/json',

body: JSON.stringify({

name: TextInputName,

email: TextInputEmail,

phone_number: TextInputPhoneNumber

})

}).then((response) => response.json())

.then((responseJson) => {

// Showing response message coming from server after inserting records.

Alert.alert(responseJson);

}).catch((error) => {

console.error(error);

});

}

7. Create custom css class named as MainContainer and TextInputStyleClass just above the AppRegistry.registerComponent line.

const styles = StyleSheet.create({
 
MainContainer :{
 
justifyContent: 'center',
flex:1,
margin: 10
},

TextInputStyleClass: {

textAlign: 'center',
marginBottom: 7,
height: 40,
borderWidth: 1,
// Set border Hex Color Code Here.
 borderColor: '#FF5722',
 
// Set border Radius.
 //borderRadius: 10 ,
}
 
});

const styles = StyleSheet.create({

MainContainer :{

justifyContent: 'center',

flex:1,

margin: 10

TextInputStyleClass: {

textAlign: 'center',

marginBottom: 7,

height: 40,

borderWidth: 1,

// Set border Hex Color Code Here.

borderColor: '#FF5722',

// Set border Radius.

//borderRadius: 10 ,

}

});

8. Add View as parent view in render’s return block and Call the MainContainer class into View.

render() {
    return (
 
<View style={styles.MainContainer}>
  
        
 
</View>
            
    );
}

render() {

return (

</View>

);

}

9. Add 3 Text Input and 1 Button component inside the View .

placeholder = Shows hint inside the Text Input.

onChangeText = Every time when user type anything in Text Input it will store the entered value in state variable.

underlineColorAndroid = Hide the Text Input base line.

style = Used to call css class.

onPress = Call the InsertDataToServer() function on button onPress.

render() {
    return (
 
<View style={styles.MainContainer}>
  
        <TextInput
          
          // Adding hint in Text Input using Place holder.
          placeholder="Enter Name"
 
          onChangeText={TextInputName => this.setState({TextInputName})}

          // Making the Under line Transparent.
          underlineColorAndroid='transparent'
 
          style={styles.TextInputStyleClass}
        />

        <TextInput
          
          // Adding hint in Text Input using Place holder.
          placeholder="Enter Email"
 
          onChangeText={TextInputEmail => this.setState({TextInputEmail})}

          // Making the Under line Transparent.
          underlineColorAndroid='transparent'
 
          style={styles.TextInputStyleClass}
        />

        <TextInput
          
          // Adding hint in Text Input using Place holder.
          placeholder="Enter Phone Number"
 
          onChangeText={TextInputPhoneNumber => this.setState({TextInputPhoneNumber})}

          // Making the Under line Transparent.
          underlineColorAndroid='transparent'
 
          style={styles.TextInputStyleClass}
        />
 
        <Button title="Insert Text Input Data to Server" onPress={this.InsertDataToServer} color="#2196F3" />
      
  
 
</View>
            
    );
  }
}

render() {

return (

<TextInput

// Adding hint in Text Input using Place holder.

placeholder="Enter Name"

onChangeText={TextInputName => this.setState({TextInputName})}

// Making the Under line Transparent.

underlineColorAndroid='transparent'

style={styles.TextInputStyleClass}

<TextInput

// Adding hint in Text Input using Place holder.

placeholder="Enter Email"

onChangeText={TextInputEmail => this.setState({TextInputEmail})}

// Making the Under line Transparent.

underlineColorAndroid='transparent'

style={styles.TextInputStyleClass}

<TextInput

// Adding hint in Text Input using Place holder.

placeholder="Enter Phone Number"

onChangeText={TextInputPhoneNumber => this.setState({TextInputPhoneNumber})}

// Making the Under line Transparent.

underlineColorAndroid='transparent'

style={styles.TextInputStyleClass}

</View>

);

}

10. Complete source code for index.android.js / index.ios.js file.

import React, { Component } from 'react';
 
import { AppRegistry, StyleSheet, TextInput, View, Alert, Button } from 'react-native';
 
class MainProject extends Component {
 
constructor(props) {
 
    super(props)
 
    this.state = {
 
      TextInputName: '',
      TextInputEmail: '',
      TextInputPhoneNumber: ''
 
    }
 
  }
 
  InsertDataToServer = () =>{

 
 const { TextInputName }  = this.state ;
 const { TextInputEmail }  = this.state ;
 const { TextInputPhoneNumber }  = this.state ;

 

fetch('https://reactnativecode.000webhostapp.com/submit_user_info.php', {
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({

    name: TextInputName,

    email: TextInputEmail,

    phone_number: TextInputPhoneNumber

  })

}).then((response) => response.json())
      .then((responseJson) => {

// Showing response message coming from server after inserting records.
        Alert.alert(responseJson);

      }).catch((error) => {
        console.error(error);
      });
 
 
  }
 
  render() {
    return (
 
<View style={styles.MainContainer}>
  
        <TextInput
          
          // Adding hint in Text Input using Place holder.
          placeholder="Enter Name"
 
          onChangeText={TextInputName => this.setState({TextInputName})}

          // Making the Under line Transparent.
          underlineColorAndroid='transparent'
 
          style={styles.TextInputStyleClass}
        />

        <TextInput
          
          // Adding hint in Text Input using Place holder.
          placeholder="Enter Email"
 
          onChangeText={TextInputEmail => this.setState({TextInputEmail})}

          // Making the Under line Transparent.
          underlineColorAndroid='transparent'
 
          style={styles.TextInputStyleClass}
        />

        <TextInput

          placeholder="Enter Phone Number"
 
          onChangeText={TextInputPhoneNumber => this.setState({TextInputPhoneNumber})}

          // Making the Under line Transparent.
          underlineColorAndroid='transparent'
 
          style={styles.TextInputStyleClass}
        />
 
        <Button title="Insert Text Input Data to Server" onPress={this.InsertDataToServer} color="#2196F3" />

  Zan you are using the URL wrong you should use like that : http://YourLocalSystemIpAddpress/submit_user_info.php . You can use IPCONFIG command to find your local system IP address.

Where do I put the DBConfig.php and submit_user_info.php?

Do I store those files on the server?

I’m using Xampp, to create and run a MYSQL database. Do you know how I can achieve this?

Cheers

  Chris i am using the 000webhost online hosting service. But to run this project on locally using Xampp, You need create a folder inside your Xampp -> htdocs -> YourFolerName . Now put both PHP files inside this folder. Now run the ipconfig command in command prompt to know your local system IP address. Now after finding the IP your URL should look like this : http://YourSystemIpAddress/submit_user_info.php . Use this URL into Fetch() method.

      Manpal here webhost means online hosting server ? Then you need to put all the PHP files to your hosting space.

Great Tutorial. I made some subtle changes because I think of newer versions of React-Native.
After I run the update I get errors: JSON Parse error: Unexpected identifier “insert” Then a bunch of errors from the core product. I have the submit_user_info.php and the DBConfig on my server.
How would I debug this. Is it the logon, the SQL query etc.
I am using Expo XDE and Genymotion to test this.

  Solex you need to check DBConfig.php file for all server configuration and also check your table name in submit_user_info.php . One more thing you are running php script on localhost or online server.

  Sandeep if you want to run PHP files then you need to put all the php files in htdocs folder. Now use http://YourWebSiteIP/YourProjectFolder/file.php inside your application.

I tried it in localhost, but it gives network error. Could it be because i try in local?

  No Berke, check your database config file or make sure when you are testing this project you have connected to internet because fetch works over internet.

Hi, Sr.
I’ve tried to use your URL and DB’s config in my Host but does’t works.
I just upload all the PHP files in my MySQL and I changed the fetch URL to mine, like this : fetch(‘https://appdejore.000webhostapp.com/ShowAllStudentsList.php’ , etc…
It works at web, but when I run in my React Native, doesn’t. A red error appears…
Can i have some help? My host is :
//Define your host here.
$HostName = “localhost”;

//Define your database name here.
$DatabaseName = “id6607105_app_teste”;

//Define your database username here.
$HostUser = “id6607105_app”;

//Define your database password here.
$HostPass = “123456789”;

Login: [email protected]
Password: 1234

      Network request fail is mostly comes when you put the serve URL without IP .
