Here is an example from Ng-Book - the Complete Book on Angularjs Book by Ari Lerner
http://jsbin.com/voxirajoru/edit?html,output where ng-form
has been used to create nested form elements and perform validation. As the each input field has same value for name
attribute so how can on the server side I can access value of all three variables by using some server side language? Let's say it's PHP
and method
is post
. Usually in PHP
I would do this:
`$_POST['dynamic_input']`
but how is it possible to access three field values coming from input field using $_POST
array?
Using the example from the link you provided, you can access form data by updating the code there with the following.
// Add the fields object as a parameter to submitForm()
<form name="signup_form" ng-controller="FormController" ng-submit="submitForm(fields)" novalidate>
// In the $scope.submitForm() function...
$scope.submitForm = function(data) {
alert(data[0].name); // Alerts name
alert(data[1].name); // Alerts password
alert(data[2].name); // Alerts email
};
If you log out the data received by submitForm(), you get the following:
[{"placeholder":"Username","isRequired":true,"$$hashKey":"004","name":"random name"},{"placeholder":"Password","isRequired":true,"$$hashKey":"005","name":"password"},{"placeholder":"Email (optional)","isRequired":false,"$$hashKey":"006","name":"email@host.com"}]
For passing to your server, package all this up as is or format it to your preference and send it to your server via the built in $http.post()
or $resource()
inside of the $scope.submitForm function.
An example of the formatted data could be:
$scope.submitForm = function(data) {
var postData = {};
postData.name = data[0].name;
postData.password = data[1].name;
postData.email = data[2].name;
... send postData to server via AJAX ...
// Creates the object: {"name":"random name","password":"password","email":"email@host.com"}
//alert(JSON.stringify(postData));
};
