Angular 11 Crud Tutorial Add New User
Angular 11 came and if you are new then you must check below link:
Friends now I proceed onwards and here is the working code snippet for Angular 11 Crud Tutorial with Service – View 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:
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Injectable({
providedIn: 'root'
})
export class CrudService {
singleuserdata:any;
constructor(private http:HttpClient) { }
...
public getsingleuser(userid)
{
return this.http.post('http://localhost/users.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:
...
export class AppComponent {
...
//variable storing single user data
userdata:any
//Variable for show hide popup
showuser = false;
//View User function
openuser(id)
{
// Initialize Params Object
var myFormData = new FormData();
// Begin assigning parameters
myFormData.append('userid', id);
//user details post request
this.crudservice.getsingleuser(myFormData);
setTimeout(()=>{
this.userdata = this.crudservice.singleuserdata;
this.showuser = true;
}, 500);
setTimeout(()=>{
$("#showuser").modal("show");
}, 800);
}
}
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-info" (click)="openuser(group.id)"> <i class="fas fa-eye"></i> </button>
</td>
</tr>
</tbody>
</table>
<!--View User Details-->
<div class="modal" id="showuser" *ngIf="showuser">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title align-center">User : {{userdata.username}}</h4>
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body text-center">
<table class="table table-hover table-bordered">
<thead>
<tr>
<th>ID</th>
<th>Email</th>
<th>Username</th>
</tr>
</thead>
<tbody>
<!-- User Dynamic data-->
<tr>
<td>{{userdata.id}}</td>
<td>{{userdata.email}}</td>
<td>{{userdata.username}}</td>
</tr>
</tbody>
</table>
</div>
</div>
</div>
</div>
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: " . $conn->connect_error);
}
//Add user
if(isset($_POST['myEmail']))
{
$sql = "INSERT INTO userdetails (email, username)
VALUES ('".$_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);
}
}
//Get single user details
elseif(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);
}
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);
}
?>
