I have a form with some input fields with the same name in order to send an array of values to the action.
<input type="text" name="myInput" value="apple"/>
<input type="text" name="myInput" value="banana"/>
<input type="text" name="myInput" value="grapefruit"/>
Now in the action I have the parameter set with getter and setter. I tried various things:
String myInput
String[] myInput
List<String> myInput
List myInput
Nothing works, the value is always null. I tested using String and sending 1 value only, that works as expected, but the array isn't getting anywhere.

I'm sending the form using POST method.
Action is quite simple:
<action name="save" class="com.mypackage.SaveAction">
<result name="success">/saveSuccess.jsp</result>
</action>
Posting this to answer my question.
In the end it seems like the size of the request was too big.

I'm fairly new to dev work and i've run into an issue. supporting an app and they want to do masking on the input for a phone number. They want to have the input be that you can only enter a phone number in a xxx-xxx-xxxx format. Currently we are checking input, but only when we write to the DB.
The app has no masking built into it and is using AngularJS 1.4.9. I was able to locate something at the below URL however I'm having issues with it not working. I can call mask in my html template but it doesn't seem to do anything.
Does anyone have any suggestions or something that is easy to implement? I don't want to re-write a ton of the app. Right now we do the validation on the write to the DB, which can be annoying as you dont get the error till you hit save and then you lost all the data you put into the form.
I'm also very new to Angular, sorry for any misunderstandings i might have.

You can do that without installing any new dependencies using ng-pattern,
running link
<ng-form name="myForm" ng-controller="mainCtrl">
<div>Phone No. :</div>
<div>
<input type="text" placeholder="913-636-7865" name="phone" ng-pattern="phoneNumbr" ng-model="phone" />
<span class="error" ng-show="myForm.phone.$error.required">Required!</span>
<span class="error" ng-show="myForm.phone.$error.minlength">Phone no not less that 10 char.</span>
<span class="error" ng-show="myForm.phone.$error.maxlength">Phone no not more than 11 char.</span>
<br><span class="error" ng-show="myForm.phone.$error.pattern">Please match pattern [913-636-7865]</span>
</div>
Using ng-mask is a good option , but make sure you have it installed and added to your dependency list
angular.module('yourApp', ['ngMask']);
here what should your html look like :
<div class="row">
<div class="col-md-6">
<label>Phone number (Home)</label>
<input type="tel"
name="phone"
mask="999-999-9999"
ng-model="phone"/>
</div>

How to store fa-icons values in checkbox in MySQL using CodeIgniter.
<form method="post" action="/action_page.php">
<div>
<input type="checkbox" id="fa-icon" name="icon" value="cat">
</div>
<div>
<button type="submit">submitt</button>
</div>
</form>
In this example, we've got a name of icon, and a value of cat. When the form is submitted, the data name/value pair will be icon=cat.
If the value attribute was omitted, the default value for the checkbox is on , so the submitted data in that case would be animal=on.
<i class="icon-<?= $this->input->post('icon'); ?>"></i> <img src="cat-<?= $this->input->post('icon'); ?>.jpg" height="42" width="42">
will give you "cat -image or cat-icon"
By using name attribute
The name attribute specifies the name of an element. The name attribute is used to reference elements in a JavaScript, or to reference form data after a form is submitted. Note: Only form elements with a name attribute will have their values passed when submitting a form.

[object Object] is automatically appeared as value in every textbox in my form. May i know what went wrong? It appears after i inserted the attribute name="searchr" in tag. Thanks.
in search.htm:
<form ng-submit="search()" ng-controller="formcontrol" name="searchr">
<input type="search" placeholder="Search here" id="text_search" ng-model="searchr.text" name="text">
in controller.js:
.controller('SearchCtrl', function($scope, $http) { }
<form name="searchr">
This creates an object of type FormController, and stores it into the scope under the name searchr.
<input name="text">
This creates an object of type NgModelController and stores it in the FormController's text attribute.
<input ng-model="searchr.text">
This tells angular that the model of the field (i.e. the text that must be displayed in the field) is searchr.text, but due to the above, searchr.textis the NgModelController object created by angular, which is part of the FormController object created by angular.
Don't use the same name for the form as the name you use to store the model of the form.

md-button with ng-click doesn't work.
So I created simple controller like following.
Wen I clicked button2 its works, but click md-button nothing happening.
controller
app.controller('MyContrl', function ($scope) {
$scope.submit = function () {
$scope.message = "asdfa";
};
});
html
{{message}}
<md-input-container>
<md-button ng-click="sumit()">Button1 - Doesn't work</md-button>
</md-input-container>
<button ng-click="submit()" value="Button2- works" class="md-raised">sdf</button>
You have a typo on the ng-click event. Change sumit() to submit().
:)
