Angular 10 Crud Tutorial – Add User

Angular 10 Crud Tutorial - Add User

Hello friends, welcome back to my blog. Today in this blog post, I am going to tell you, Angular 10 Crud Tutorial – Add User.

Angular Crud

Angular 10 came and if you are new then you must check below two links:

  1. Angular10 for beginners
  2. Angular10 Basic Tutorials

Friends now I proceed onwards and here is the working code snippet for Angular 10 Crud Tutorial – Add User and please use carefully this to avoid the mistakes:

1. Firstly friends we need fresh angular 10 setup and for this we need to run below commands but if you already have angular 10 setup then you can avoid below commands. Secondly we should also have latest node version installed on our system:

npm install -g @angular/cli 

ng new angularcrud //Create new Angular Project

cd angularcrud // Go inside the Angular Project Folder

ng serve --open // Run and Open the Angular Project

http://localhost:4200/ // Working Angular Project Url

 

2. Now friends, here we need to run below commands into our project terminal to install bootstrap(for good looks), jquery to support bootstrap and sweetlaert(for beautiful success popups) modules into our angular application:

npm i bootstrap --save

npm i jquery --save

npm i --save sweetalert2

ng serve --o

 

3. Now friends, here we need to add below  into our angular.json file to get modules styles and scripts:

...
"styles": [
              ...
              "node_modules/bootstrap/dist/css/bootstrap.min.css",
              "node_modules/sweetalert2/src/sweetalert2.scss",
              
            ],
            "scripts": [
              ...
              "node_modules/jquery/dist/jquery.min.js", 
              "node_modules/bootstrap/dist/js/bootstrap.min.js", 
              "node_modules/sweetalert2/dist/sweetalert2.js", 
              
            ]
...

 

4. Now friends we just need to add below code into src/app/app.module.ts file:

...
import { NgModule } from '@angular/core';
import { ReactiveFormsModule } from '@angular/forms';
import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [
    ReactiveFormsModule,
    HttpClientModule
  ],
...

 

5. Now friends we just need to add below code into src/app/app.component.ts file:

...
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
import { HttpClient } from '@angular/common/http';
import Swal from 'sweetalert2/dist/sweetalert2.js';

export class AppComponent {
...

//add user form start

registerForm: FormGroup;
submitted = false;

constructor(private http: HttpClient, private formBuilder: FormBuilder){}

//Add user form actions
get f() { return this.registerForm.controls; }

onSubmit() {
  
  this.submitted = true;
  // stop here if form is invalid
  if (this.registerForm.invalid) {
      return;
  }
  //True if all the fields are filled
  if(this.submitted)
  {
    
    // Initialize Params Object
     var myFormData = new FormData();
  
   // Begin assigning parameters
  
      myFormData.append('myUsername', this.registerForm.value.firstname);
      myFormData.append('myEmail', this.registerForm.value.email);
  
    //post request
    return this.http.post('http://localhost/save.php/'
    , myFormData).subscribe((res: Response) => {
      
      
      
        //sweetalert message popup
        Swal.fire({
        title: 'Hurray!!',
        text:   this.registerForm.value.firstname+" has been added successfully",
        icon: 'success'
      });
        
        
      
  });
  }
 
}

  ngOnInit() {
    //Add User form validations
    this.registerForm = this.formBuilder.group({
    email: ['', [Validators.required, Validators.email]],
   
    firstname: ['', [Validators.required]]
    });
  }

}

 

6. Now friends we just need to add below code into src/app/app.component.html file to see the output on browser:

<form [formGroup]="registerForm" (ngSubmit)="onSubmit()">
        <div class="row">
           <div class="col-sm-6">
              <div class="form-group">
                    <label>Username</label>
                    <input type="text" formControlName="firstname" class="form-control" [ngClass]="{ 'is-invalid': submitted && f.firstname.errors }" />
                    <div *ngIf="submitted && f.firstname.errors" class="invalid-feedback">
                          <div *ngIf="f.firstname.errors.required">Name is required</div>
                    </div>
                 </div>
           </div> 
           <div class="col-sm-6">
              <div class="form-group">
                 <label>Email</label>
                 <input type="text" formControlName="email" class="form-control" [ngClass]="{ 'is-invalid': submitted && f.email.errors }" />
                 <div *ngIf="submitted && f.email.errors" class="invalid-feedback">
                    <div *ngIf="f.email.errors.required">Email is required</div>
                    <div *ngIf="f.email.errors.email">Email must be a valid email address</div>
                 </div>
              </div>
           </div>
           
           
       </div>
       <button type="submit" class="btn btn-primary">Submit</button>
     </form>

 

7. Now friends here is my php code snippet to save angular 10 form data and I added this code into my xampp/htdocs/save.php file:

//Please create users database inside phpmysql admin and create userdetails tabel and create id, email and username fields

<?php

//Please create users database inside phpmysql admin and create userdetails tabel and create id, email and username fields

$servername = "localhost";
$username   = "root";
$password   = "";
$dbname     = "users";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 


    $sql = "INSERT INTO userdetails (email, username)
        VALUES ('".$_POST['myEmail']."', '".$_POST['myUsername']."')";
    if (mysqli_query($conn,$sql)) {
    $data = array("data" => "You Data added successfully");
        echo json_encode($data);
    } else {
        $data = array("data" => "Error: " . $sql . "<br>" . $conn->error);
        echo json_encode($data);
        
    }

?>
