Angular 10 Crud Tutorial – Edit User

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

Guys before starting this, I must say, you have to follow below tutorial links to understand this post:
AngularCrud Tutorial – Add User
Angular Crud Tutorial – View user
Angular Crud Tutorial – Delete user

Angular10 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 – Edit 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:

Guys, you can skip this step if you already have angular 10 fresh setup:

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  modules into our angular application:

Guys, you can skip this step if you already have these modules:

npm i bootstrap --save

npm i jquery --save

npm install --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 {

//Edit Form

editForm: FormGroup;
submitted = false;
data:any;
userdata:any;
showedituser = false;
userID:any;

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

  this.http.get('http://localhost/save.php').subscribe(data => {
    this.data = data;
    
    }, error => console.error(error));
}

//Edit User Button Click

edituser(id)
{
  // Initialize Params Object
  var myFormData = new FormData();
  this.showedituser = true;
  // Begin assigning parameters

  myFormData.append('userid', id);
  

return this.http.post('http://localhost/save.php/'
  , myFormData).subscribe((res: Response) => {
    this.userdata = res[0];

    //set values in edit user form
    this.editForm.controls["firstname"].setValue(this.userdata.username);
    this.editForm.controls["email"].setValue(this.userdata.email);
    this.userID = this.userdata.id;

    //edit user modal show
    $("#editModal").modal("show");
    
  });
}

//Update User Function
get f() { return this.editForm.controls; }
onSubmit() {
  
  this.submitted = true;
  // stop here if form is invalid
  if (this.editForm.invalid) {
      return;
  }
  //True if all the fields are filled
  if(this.submitted)
  {
    
    // Initialize Params Object
    var myFormData = new FormData();
  
  // Begin assigning parameters
  
  myFormData.append('updateUsername', this.editForm.value.firstname);
  myFormData.append('updateEmail', this.editForm.value.email);
  myFormData.append('updateid', this.userID);
  
  return this.http.post('http://localhost/save.php/'
    , myFormData).subscribe((res: Response) => {
      
      

      $("#editModal").modal("hide");
      
        //sweetalert message popup
        Swal.fire({
        title: 'Hurray!!',
        text:   "User has been updated successfully",
        icon: 'success'
      });
        
        //refetch users from datatabse
        return this.http.get('http://localhost/save.php').subscribe(data => {
          this.data = data;
         }, error => console.error(error));
        
      
  });
  }
 
}
ngOnInit() {
    //Edit form validations
    this.editForm = 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:

<table class="table table-hover table-bordered">
        <thead>
          <tr>
            <th>ID</th>
            <th>Email</th>
            <th>Username</th>
            <th>Actions</th>
          </tr>
        </thead>
        <tbody>
       
           
              <tr *ngFor="let group of data">
                <td>{{group.id}}</td>
                <td>{{group.email}}</td>
                <td>{{group.username}}</td>
       
                <td>
                  <button class="bg-info"> <i class="fas fa-eye"></i> </button>
                  <button class="bg-warning" (click)="edituser(group.id)"> <i class="fas fa-edit"></i> </button>
                  <button class="bg-danger"> <i class="fas fa-trash"></i> </button>
                </td>
              </tr>
           
         
         
          
        </tbody>
      </table>

<div class="modal" id="editModal" *ngIf="showedituser">
        <div class="modal-dialog">
          <div class="modal-content">
          
            <div class="modal-header">
              <h4 class="modal-title align-center">Edit : {{userdata.username}}</h4>
              <button type="button" class="close" data-dismiss="modal">&times;</button>
            </div>
            
            <div class="modal-body">
            
              <form [formGroup]="editForm" (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">Update</button>
                </form>
             
                    
            
              
           
            </div>
          
            <div class="modal-footer">
              <button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
            </div>
          </div>
        </div>
      </div>

7. Now friends we just need to add below code into src/index.html file to add font-awesome icons and some custom styling:

<head>
  ...
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
  <link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css">
  <style>
   .bg-primary, .bg-warning, .bg-danger, .bg-info{border:none; margin-right: 3px;}
   .fa-edit:before,  .fa-user:before, .fa-trash:before, .fa-eye:before{color: #fff;}
   .btn{margin-right: 3px;}
  </style>
</head>

8. Now friends here is my php code snippet to fetch data and show  into angular 10  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);
} 



//Get single user details
if(isset($_POST['userid']))
{
    $trp = mysqli_query($conn, "SELECT * from userdetails where id =".$_POST['userid']);
    $rows = array();
    while($r = mysqli_fetch_assoc($trp)) {
        $rows[] = $r;
    }
    print json_encode($rows);
}

//Update user
elseif(isset($_POST["updateid"]))
{
    $sql = "UPDATE userdetails SET email='".$_POST["updateEmail"]."', username='".$_POST["updateUsername"]."'  WHERE id=".$_POST["updateid"];

    if ($conn->query($sql) === TRUE) {
    
       $data = array("data" => "Record updated successfully");
        echo json_encode($data);
    } else {
    
    $data = array("data" => "Error updating record: " . $conn->error);
    echo json_encode($data);
    }
}
else
{
    //get all users details
    $trp = mysqli_query($conn, "SELECT * from userdetails");
    $rows = array();
    while($r = mysqli_fetch_assoc($trp)) {
        $rows[] = $r;
    }
    print json_encode($rows);
}
?>
