I've searched all over the internet that how to form validate data sent by Angular js $http POST request in codeigniter.
For clear understanding I've posted completed HTML data. I believe that most of the developer are looking for this solution.
Here is my HTML Form:
<!DOCTYPE html>
<html>
<head>
<style>
input[type="text"].ng-invalid{border: 1px solid red; }
</style>
</head>
<body ng-app="app" ng-controller="ctrl">
<form name="test_form" ng-submit="send_data()">
<input type="text" name="email" ng-model="email">
<span ng-show="test_form.email.$invalid - required">Required</span>
<input type="password" name="password" ng-model="password">
<span ng-show="test_form.email.$invalid - required">Required</span>
<button type="submit">Submit</button>
</form>
<script src="<?php echo base_url('assets/angular/angular.min.js'); ?>" type="text/javascript">
</script>
<script>
angular.module('app', [])
.controller('ctrl', function ($scope, $http) {
$scope.send_data = function () {
$http({
method: "POST",
url: "<?php echo base_url('login/test_angular_validate'); ?>",
data: {email: $scope.email, password: $scope.password},
headers : {'Content-Type': 'application/x-www-form-urlencoded'}
}).then(function (success) {
console.log(success);
}, function (error) {
})
}
});
</script>
</body>
</html>
Backend Codeigniter Login Controller Function
<?php
public function test_angular_validate() {
$form_data = json_decode(file_get_contents("php://input"), true);
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');
$this->form_validation->set_rules('email', 'email', 'required|min_length[3]');
$this->form_validation->set_rules('password', 'password', 'required');
if ($this->form_validation->run() == FALSE) {
echo 'failed';
print_r(validation_errors());
} else {
echo 'success';
}
}
?>
When is send html form data using angular $http POST request I'm unable to validate that data using codeigniter form validation library. It throws an validation error as given in this image.

Codeigniter access the super global $_POST for its validation. Your JSON data is not binded to this superglobal. So you need to set it up manually:
$_POST = json_decode(file_get_contents("php://input"), true);
You can also POST your data URLENCODED. In that way you your POST params will be available in $_POST without a manually set.
$http({
method: 'POST',
url: "<?php echo base_url('login/test_angular_validate'); ?>",
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
data: {
email: $scope.email,
password: $scope.password
},
transformRequest: function(obj) {
var str = [];
for(var p in obj)
str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
return str.join("&");
},
}).then(function (success) {
console.log(success);
}, function (error) {
});
