Problems populating a select list with angular js and php - php

Question

I am trying to populate a select list with data from my db (php & mysql). I am working with AngularJs and Angular Material. So for i am not able to show the data from the db in the list
db situation:
tblProjectType -> name of table
2 rows:
id_ProjectType
project_type
Any help or pointers would be great.
This is my html code:
<form ng-controller="AppCtrl">
<div layout="row">
<md-select-label>Project type</md-select-label>
<md-select ng-model="project_type" name="project_type" placeholder="Choose a project type" id="containerProjectType">
<md-option ng-repeat="projecttype in projecttypes" value="{{projecttype.id_ProjectType}}">{{projecttype.project_type}}</md-option>
</md-select>
</div>
</form>
The code of my app.js is:
var app = angular.module("DragDrop", ['ngMaterial']);
app.controller('AppCtrl', function($scope, $mdDialog, $http) {
$scope.projectTypeInfo = [];
var getProjectTypeFunction = function(succesFn, errorFn)
{
$http.get('db.php?action=get_ProjectType_info')// call to the server
.succesFn(function(data){
succesFn(data); //call the function passed into getProjectTypeFunction with the data from the server
console.log('Retrieved data from server');
})
.error(errorFn || function() {
console.log("Error in retrieving data from server");
})
}
this.reloadProjectTypeList = function()
{
getProjectTypeFunction(
/* success function */
function(data) {
//debugger;
$scope.projectTypeInfo = data;
//digest recycle
//if (!$scope.$$phase) { $scope.$apply(); }
},
/* error function */
function()
{
alert("Server load failed");
})
};
My php code is:
<?php
include('config.php');
//echo ('test' . $_GET['action']);
switch($_GET['action']) {
case 'get_ProjectType_info' :
get_ProjectType_info();
break;
}
/** Function to data from tblProjectType **/
function get_ProjectType_info(){
$qry = mysql_query('SELECT * from tblProjectType');
echo("test");
//echo(qry);
$data = array();
while($rows = mysql_fetch_array($qry))
{
$data[] = array(
"id_ProjectType" => $rows['id_ProjectType'],
"project_type" => $rows['project_type']
);
}
print_r(json_encode($data));
return json_encode($data);
}
?>

So for starters lets clean up your JS. We can reduce what you have to this:
var app = angular.module("DragDrop", ['ngMaterial']);
app.controller('AppCtrl', function($scope, $mdDialog, $http)
{
$scope.projectTypeInfo = [];
$scope.getProjectTypeFunction = function()
{
$http.get('db.php?action=get_ProjectType_info')
.success(function(data, status, headers, config)
{
$scope.projectTypeInfo = data;
console.log('Retrieved data from server');
console.log(data);
})
.error(function(data, status, headers, config)
{
console.log("Error in retrieving data from server");
console.log(data,status);
});
};
$scope.getProjectTypeFunction(); //-- call the function that invokes $http.get()
};
In PHP your function needs to echo the data via echo json_encode($data);, not return it (as stated by #Avalanche).
Now, your console should output something, but you need to remove console.log("test"); from your PHP as that will surely cause an error.
edit
Currently your repeat states:
<md-option ng-repeat="projecttype in projecttypes" value="{{projecttype.id_ProjectType}}">{{projecttype.project_type}}</md-option>
We have stored your data in $scope.projectTypeInfo therefore it needs to be modified to:
<md-option ng-repeat="projecttype in projectTypeInfo" ng-value="projecttype.id_ProjectType">{{projecttype.project_type}}</md-option>
