How to get data using php and angylarJS - php

Question

I hope that you are in good mood :). I'm trying to return data which depend on text from user using AngularJS and php. So I create file php which contain my query and using $http.get in AngularJS. My problem is I want to integrate value of input in mysql query, but always using angular. I tried many times but nothing works To be more clear, here is muy code:
app.js
app1.controller('autoCompleteCTRL',function($scope,$rootScope,$http) {
$scope.search = function(){
$scope.$watch('searchText', function() {
console.log($scope.searchText);
});
$http({
method: "get",
url: "../SearchResultsQuery.php",
dataType: 'json',
data: { 'userText': $scope.searchText},
async: false,
params: {action: "get"}
}).success(function(data, status, headers, config) {
alert(data);
}).error(function(data, status, headers, config) {
alert(error);
});
};
}
index.html
<input type="text" placeholder="Search for items" id="textFiled" class="input" ng-model="searchText" ng-change="search()" />
app.php
<?php
$conn=pgsqlCon();
$searchText = mysql_real_escape_string(userText);
$query='SELECT * FROM planet_osm_roads AS a, to_tsquery_partial(\'%.$searchText.%\') AS query
WHERE ts_road ## query';
$result = pg_query($conn,$query);
$myarray = array();
while ($row = pg_fetch_row($result)) {
$myarray[] = $row;
}
pg_close($conn);
echo json_encode($myarray);
?>
I hope that you understand me Thanks for advance :)

Answer 1

try to make your http request like this:
app.controller('TestCtrl', function ($scope, $http){
$scope.search = function(){
$http.post('../app.php', {searchText: $scope.searchText})
.success(function (response){
console.log(response);
})
.error(function (response){
console.log(response);
});
}
});
app.php
<?php
$data = file_get_contents("php://input");
$searchText = mysql_real_escape_string($data['searchText']);
/* database code */
?>
This should work.

In your app.js file, instead of this line:
data: { 'userText': $scope.searchText}
write:
params: { 'userText': $scope.searchText}
and remove this line:
params: {action: "get"}
This way it will transfer userText variable through request URL as a GET parameter.
In your app.php file, instead of:
$searchText = mysql_real_escape_string(userText);
write:
$searchText = mysql_real_escape_string($_GET['userText']);
This will populate your $searchText php variable with text from client application (AngularJS). I'm not sure about your postgresql query. Your question title is mysql - How to get data..., but in your php code sample you use postgres extension to build query. But that's a different story I guess.
