Friends now I proceed onwards and here is the working code snippet for Angular 11 Crud Tutorial with Service – Delete User and please use carefully this to avoid the mistakes:

1. Now friends we just need to add below code into src/app/crud.service.ts file and please follow only highlighted code:

...
export class CrudService {
  
  singleuserdata:any;
  constructor(private http:HttpClient) { }
  //get all user details
  public getusers()
      {
        
          return this.http.get('http://localhost/reactimageupload.php');
      }

  
  //delete user
  public deleteuser(userid)
  {
    return this.http.post('http://localhost/reactimageupload.php/'
    , userid).subscribe((res: Response) => {
      this.singleuserdata = res[0];
      
      
    });
  }

    
}

 

2. Now friends we just need to add below code into src/app/app.component.ts file and please follow only highlighted code:

...
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
import Swal from 'sweetalert2/dist/sweetalert2.js';
import { CrudService } from './crud.service'; 
declare let $: any;
export class AppComponent  {
  ...
  constructor(private crudservice: CrudService, private formBuilder: FormBuilder) {}
  data = [];
 

    //Delete User
    deleteuser(id)
    {
      // Initialize Params Object
      var myFormData = new FormData();
   
      
      // Begin assigning parameters
      myFormData.append('deleteid', id);
      this.crudservice.deleteuser(myFormData);
      //sweetalert message popup
      Swal.fire({
        title: 'Hurray!!',
        text:   "User has been deleted successfully",
        icon: 'success'
      });
      $('#datatableexample').DataTable().destroy();
        this.crudservice.getusers().subscribe((ret: any[])=>{
        
          this.data = ret;
         
          setTimeout(()=>{                          
            $('#datatableexample').DataTable( {
              pagingType: 'full_numbers',
              pageLength: 5,
              processing: true,
              lengthMenu : [5, 10, 25],
              order:[0,"desc"]
          } );
          }, 500);
          
          
      });
        

    }
}

 

3. Now friends we just need to add below code into src/app/app.component.html file to see the output on browser and please follow only highlighted code:

<!--Datatable with User Details-->
  <table class="table table-hover table-bordered" id="datatableexample">
    <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-danger" (click)="deleteuser(group.id)"> <i class="fas fa-trash"></i> </button>
            </td>
          </tr>
       
     
     
      
    </tbody>
  </table>

 

4. Now friends, we have to add some code into our src/index.html file for font icons:
<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>
   .fa-eye:before{color: #fff;}
   
  </style>
</head>

 

5. Now friends here is my php code snippet to fetch and show  into angular 11  and I added this code into my xampp/htdocs/users.php file and please follow only highlighted code:

//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);
} 




//Delete user
if(isset($_POST['deleteid']))
{
    $sql = mysqli_query($conn, "DELETE from userdetails where id =".$_POST['deleteid']);
    if ($sql) {
        
        $data = array("data" => "Record deleted successfully");
        echo json_encode($data);
      } else {
      
        $data = array("data" =>"Error deleting record: " . mysqli_error($conn));
        echo json_encode($data);
      }
}

else
{
    //get all users details
    $trp = mysqli_query($conn, "SELECT * from userdetails ORDER BY id DESC");
    $rows = array();
    while($r = mysqli_fetch_assoc($trp)) {
        $rows[] = $r;
    }

   

    print json_encode($rows);
}
?>
