I would like to make a http.post request, to receive a list of objects from PHP with .subscribe.
When I do that, I receive something like a string which contains my objects.
But in a *ngFor loop, the console says me the list is an undefined variable.
Here is my code :
list-master.ts
/////
objet01 = {ville: 'Bordeaux', prix: '69€'};
objet02 = {ville: 'Lille', prix: '45€'};
objs = [this.objet01, this.objet02];
/////
tempproj;
constructor(public navCtrl: NavController, private navParams: NavParams, public http: Http) {
this.http = http;
this.getprojets();
}
getprojets() {
var link = 'http://*****/getprojets.php';
var myData = JSON.stringify({value: 'true'});
this.http.post(link, myData)
.subscribe(data => {
this.tempproj = data["_body"];
console.log('OKOK ' + this.tempproj + ' OKOK');
}, error => {
console.log("Oooops!");
});
}
Here is getprojets.php:
$postdata = file_get_contents("php://input");
if (isset($postdata)) {
$request = json_decode($postdata);
$value = $request->value;
if ($value === 'true' ) {
$bdd = new PDO('***', '***', '***', array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));
$bdd->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
$query = $bdd->prepare("SELECT * FROM projetsapparts") or die('Login invalide');
$query->execute();
$liste = array();
class projet1 {};
while ($projet = $query->fetch()) {
$projet1 = new projet1;
$projet1->ville = $projet['ville'];
$projet1->photo = $projet['photo'];
$liste[] = $projet1;
}
echo json_encode($liste);
}
}
else {
echo 'Erreur postdata';
}
And then, the list-master.html:
<ion-slides class="marketslide" autoplay="3000" loop="true">
<ion-slide *ngFor="let appart of tempproj">
<ion-card (tap)="showplvdetails()">
<img src="{{appart.photo}}">
<div class="card-title">{{appart.ville}}</div>
</ion-card>
</ion-slide>
</ion-slides>
In the console, the var tempproj contains 3 entries, it looks like a list of objects : [{"ville":"Reims","photo":"http:******.jpg"},{"ville":"Paris","photo":"http:******.jpg"},{"ville":"Amsterdam","photo":"http:******.jpg"}]
But, I have this error:
Cannot read property 'hasAttribute' of undefined
When in the .html file, I replace the var tempproj by the var objs (which is set in .ts file instead of coming from PHP) in the *ngFor, all is working fine.
Why does the list of objects from PHP be undefined?
On the *ngFor="let appart of tempproj" line, does the 'appart' can be an object?
Please help me, I only find solutions for JavaScript and Angular 2. I'm on it for 5 days.
