Hello friends, welcome back to my blog. Today in this blog post, I am going to show you, Angular 11 Crud Tutorial – View User.
Guys before starting this, I must say, you have to follow below tutorial link to understand this post:
Angular 11 Crud Tutorial – Add 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 – View User and please use carefully this to avoid the mistakes:
1. Firstly friends we need fresh angular 11 setup and for this we need to run below commands but if you already have angular 11 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 modules into our angular application:
npm i bootstrap --save npm i jquery --save 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",
],
"scripts": [
...
"node_modules/jquery/dist/jquery.min.js",
"node_modules/bootstrap/dist/js/bootstrap.min.js",
]
...
4. Now friends we just need to add below code into src/app/app.module.ts file:
...
import { HttpClientModule } from '@angular/common/http';
@NgModule({
imports: [
HttpClientModule
],
...
5. Now friends we just need to add below code into src/app/app.component.ts file:
...
import { HttpClient } from '@angular/common/http';
declare let $: any;
export class AppComponent {
...
//Declare data storing variables
data:any;
userdata:any;
//For modal popup hiding first time
showuser = false;
constructor(private http: HttpClient){
//get request
this.http.get('http://localhost/save.php').subscribe(data => {
this.data = data;
}, error => console.error(error));
}
openuser(id)
{
// Initialize Params Object
var myFormData = new FormData();
//removing modal hiding
this.showuser = true;
// Begin assigning parameters
myFormData.append('userid', id);
//user details post request
return this.http.post('http://localhost/save.php/'
, myFormData).subscribe((res: Response) => {
this.userdata = res[0];
$("#myModal").modal("show");
});
}
}
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" (click)="openuser(group.id)"> <i class="fas fa-eye"></i> </button>
<button class="bg-warning"> <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="myModal" *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>
7. Now friends we just need to add below code into src/index.html file to add font-awesome 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>
.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 11 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);
}
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);
}
?>
