New to angular, new to life:
I have a small email form.
This works:
<form method="post" name="form" role="form" ng-controller="contactForm" ng-submit="form.$valid && sendMessage(input)" novalidate class="form-horizontal">
<p ng-show="success"><b>We received your message</b></p>
<p ng-show="error">Something wrong happened!, please try again.</p>
<label for="name">Name:</label><br>
<input type="text" id="name" name="name" ng-model="input.name" required><br>
<label for="email">Email:</label><br>
<input type="email" id="email" name="email" ng-model="input.email" required><br>
<label for="messsage">Message:</label><br>
<textarea id="messsage" name="message" ng-model="input.message" ngMaxlength='2000' required></textarea><br>
<button type="submit" name="submit" ng-disabled="error" value="submit">Submit</button>
</form>
This does not work:
<form method="post" name="form" role="form" ng-controller="contactForm" ng-submit="form.$valid && sendMessage(input)" novalidate class="form-horizontal">
<p ng-show="success"><b>We received your message</b></p>
<p ng-show="error">Something wrong happened!, please try again.</p>
<label for="name">Name:</label><br>
<input type="text" id="name" name="name" ngModel="input.name" required><br>
<label for="email">Email:</label><br>
<input type="email" id="email" name="email" ngModel="input.email" required><br>
<label for="messsage">Message:</label><br>
<textarea id="messsage" name="message" ngModel="input.message" ngMaxlength='2000' required></textarea><br>
<button type="submit" name="submit" ng-disabled="error" value="submit">Submit</button>
</form>
for the 2 inputs and the textarea if I use 'ng-model' the email sends, but when the page loads, the form loads invalid.
If i use 'ngModel' the form loads clean, but the email wont submit.
controller here:
app.controller("contactForm", ['$scope', '$http', function($scope, $http) {
$scope.success = false;
$scope.error = false;
$scope.sendMessage = function( input ) {
$http({
method: 'POST',
url: 'processForm.php',
data: input,
headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
})
.success( function(data) {
if ( data.success ) {
$scope.success = true;
$scope.input.name="";
$scope.input.email="";
$scope.input.message="";
} else {
$scope.error = true;
}
} );
}

Warning:
There is some annoying red background
.ng-invalid{
background-color:red;
}
}]);
That's how we know it is loading invalidly.
The annoying red background is the form, since you have a very generic rule set by .ng-invalid, the class will be set on the form as well. You would need to make it more specific for the inputs and controls within the form.
Example:
input.ng-invalid,
textarea.ng-invalid {
background-color:red;
}
Or just reset rule for form.ng-invalid
To add on there is nothing called ngModel it is ng-model. using the former one doesn't do anything but adds a dummy attribute on the element, it has no effect. It is angular way of directive naming, since html is case insensitive the one way angular can identify the directive from attribute or element name (based on the restriction). It converts it to camelCasing to evaluate and process respective directive (or directives attribute bindings). When you do not have ng-model specified and if the form or control does not have novalidate attribute, then the browser's HTML5 validation kicks in that is what you see as inconsistency. Using HTML5 novalidate attribute makes sure no native validation happens on the form.
ng-model is when u write the view (html part).
ngModel is used when one write a custom directive. It is placed in the "require:" param so that u can access,
variables like ngModel.$modelValue
ngModel.$modelValue will have the latest content which has been typed by the user at realtime. So, it can be used for validations, etc.
View code:-
<!doctype html>
<html ng-app="plankton">
<head>
<script src="/bower_components/angular/angular.min.js"></script>
<script src="/scripts/emailing/emailing.directive.js"></script>
</head>
<body ng-controller="EmailingCtrl">
<div>
<label>Enter Email: </label>
<emailing id="person_email" ng-model="email_entered"></emailing>
</div>
</body>
</html>
Custom directive:-
(function() {
'use strict';
angular.module('plankton', [])
.directive('emailing', function emailing(){
return {
restrict: 'AE',
replace: 'true',
template: '<input type="text"></input>',
controllerAs: 'vm',
scope: {},
require: "ngModel",
link: function(scope, elem, attrs, ngModel){
console.log(ngModel);
scope.$watch(function(){ return ngModel.$modelValue;
}, function(modelValue){
console.log(modelValue);//awesome! gets live data entered into the input text box
});
},
};
})
.controller('EmailingCtrl', function($scope){
var vm = this;
});
})();

Have an angular form that I'm passing into my controller.
When I open browser to inspect form, it is undefined. I've tried changing the name of the form, and moving the form tag to enclose the entire body. Here is my form:
<form layout-padding id="form-container" ng-controller="RegisterController as RgCtrl" layout="column" ng-cloak name="projectForm">
<div id="content-row-header">What is your email?</div>
<md-input-container class="md-block md-input-focused">
<label>Email</label>
<input required type="email" name="email" ng-model="email"
minlength="10" maxlength="100" ng-pattern="/^.+#.+\..+$/" />
<div ng-messages="projectForm.email.$error" role="alert">
<div ng-message-exp="['required', 'minlength', 'maxlength', 'pattern']">
Your email must be between 10 and 100 characters long and look like an e-mail address.
</div>
</div>
</md-input-container>
<div id="content-row-header">Set a password</div>
<md-input-container class="md-block md-input-focused">
<label>Password</label>
<input required name="password" ng-model="password">
<div ng-messages="projectForm.password.$error">
<div ng-message="required">This is required.</div>
</div>
</md-input-container>
</form>
Here is my function call:
<md-button id="orange-button" ui-sref="app.unauthenticated.purchase.agent" ng-click="doRegistration(projectForm)" flex>Create Account</md-button>
and here is my controller:
(function () {
'use strict';
angular
.module('app.auth.register')
.controller('RegisterController', RegisterController);
/** #ngInject */
function RegisterController($scope, $auth, $log, $location,$rootScope,$state,app_auth,$stateParams) {
// Data
var vm = this;
// Methods
$scope.doRegistration = function (form) {
console.log(form);
app_auth.register(form.email.$viewValue,form.password.$viewValue,form.passwordConfirm.$viewValue);
};
// $scope.goHome = function () {
/
/ $state.go('app.public');
// };
}
})();
right now when that console.log(form) runs, form is undefined
If you have some conditional directive in the form:
<form name="myForm" ng-if="someVariable">
Then $scope.myForm will be undefined in your controller.
Besides, you should use ng-submit.
you are using a directive.
The directive scope is different from the controllers. That's why you are not able to see the form reference.
GO to directive implementation and add:
scope: {
projectForm: '=',
},
reference: https://www.sitepoint.com/form-based-directives-angularjs/
name attribute will bind form controller to $scope, so you have name="projectForm" in your controller you should be able
to use $scope.projectForm

Register Controller had to encompass the form definition and function that took in a form as argument
I need to get information from my online form added in to my URL string and get it submitted to the dialler.
I have a working URL string that submits data to our dialler ok.
I need to get the first name, last name and phone number from the form submission in to the URL string.
This is how the URL string looks;
http://domain.com/scripts/api.php?user=admin&pass=password&function=add_lead&source=MobileOp&phone_number=07000000000&phone_code=44&list_id=3002&first_name=NAME&last_name=SURNAME&rank=99&campaign_id=campaign&callback=Y&callback_datetime=NOW
This is the form I have;
<form id="contact_form" method="post" action="">
<div class="contactform">
<fieldset class="large-12 columns">
<div class="required">
<label>Your First Name:*</label>
<input name="first_name" type="text" class="cms_textfield" id="first_name" value="" size="25" maxlength="80" required="required" />
</div>
<div class="required">
<label>You Last Name:*</label>
<input name="last_name" type="text" class="cms_textfield" id="last_name" value="" size="25" maxlength="80" required="required" />
</div>
<div class="required">
<label>Phone Number:*</label>
<input name="phone_number" type:"number" id="phone_number" size="25" maxlength="11" required="required"></input>
</div>
</fieldset>
<p class="right"><strong>Call us now on 01656 837180</strong></p>
<div class="submit"><input type="submit" value="Submit" class="button small radius"></div>
</div>
</form>
I am struggling to get anywhere with this. I have a basic knowledge of PHP.
If you change your form to method="GET" and the action to your url action="http://domain.com/scripts/api.php" it will include it in the URL string. That said, showing a user's password as a query string variable is probably a bad idea in the long run.
Instead, you can process the input from the form in PHP by referring to the $_POST array in your code. For example, to get the first name you'd just use $_POST['first_name']
Change
<form id="contact_form" method="post" action="">
to
<form id="contact_form" method="GET" action="">
(notice the method 'GET'). GET sends form variables through the URL.
You can use PHP for this.
if you have an input field of name attribue 'first_name', It'll be stored in the variable $_POST['first_name'] in case of POST as method and $_GET['first_name'] in case of GET method
If you have a url
http://domain.com/scripts/api.php?user=admin&pass=password&function=add_lead&source=MobileOp&phone_number=07000000000&phone_code=44&list_id=3002&first_name=NAME&last_name=SURNAME&rank=99&campaign_id=campaign&callback=Y&callback_datetime=NOW,
notice the x=y pattern repeating in it, like user=admin. Here, the first element, x becomes the key to tha PHP array and the second becomes the value.
You can use this function. on your submission page
<script type="text/javascript">
function iter() {
var str = "";
$("#contact_form .contactform .required :input").each(function () { // Iterate over inputs
if ($(this).attr('id')) {
str += $(this).attr('id') + "=" + $(this).val() + "&"; // Add each to features object
}
});
str = str.substring(0, str.length - 1);
$.ajax({
type: "GET",
url: "http://domain.com/scripts/api.php",
data: str,
async: true,
error: function (error) {
},
success: function (data) {
}
});
}
</script>
just attach it to the submit button as shown below
$("#contact_form .submit").on("click", function () {
iter();
return false;
});
i'm not a very good programmer at all but i need a little help with a webpage i'm making.
Here's what I have for a form:
<form name="input" action="name.htm" method="get">
Name: <input type="text" name="name">
<input type="submit" value="Submit">
</form>
What I want it to do is if I put in the name Fred and press submit Button, it will go to a certain page. Any other name will link to another page or popup with an error saying, "tough luck!" or something like that.
Sorry, I couldn't find anything this specific on the web anywhere. I'm sure it's simple, I'm just confused with how this works. Thank you!
using front-end only, i'd be using javascript or jquery. meaning you don't need a form element inside it.
<script>
$("#submitButton").click(function(){
window.location.replace("enter url here")
})
</script>
you can do it with JS/jQuery:
HTML
<form name="input" action="name.htm" method="get">
Name: <input type="text" name="name" id="name">
<input type="submit" id="submit-button" value="Submit">
</form>
JS
$("#submit-button").click(function(){
if ($("#name").val() == "Fred")
location.href = "goodurl";
else
location.href = "badurl";
});
There are 2 options to solve this problem.
To use JavaScript for input value's validation and depending on it to redirect user
To use server side language to check the passed value
The first option will be easier for you I guess.
You can do something like:
Name: <input type="text" name="name">
<input type="button" value="Submit" onClick="redirect();">
<script type="text/javascript">
function redirect() {
var value = document.getElementsByName('name')[0].value;
if (value == 'Fred') {
window.location.href='http://url1';
} else {
window.location.href='http://url2';
}
}
</script>
Links: 'url1' and 'url2' must be replaced with your URLs
Just add the following code in your HTML file and try it out:
<script type="text/javascript">
function handleSubmit() {
var name = document.input.name.value;
if(name == 'Fred') {
location.href = "http://www.google.com";
} else if (name == 'Jack') {
location.href = "http://www.yahoo.com";
} else {
alert("Tough Luck");
}
}
</script>
<form name="input" action="name.htm" method="get">
Name: <input type="text" name="name">
<input type="button" value="Submit" onclick="handleSubmit();">
</form>
I have a form with two required input fields:
<form>
<input type="tel" name="telephone" required>
<input type="tel" name="mobile" required>
<input type="submit" value="Submit">
</form>
Is it possible to get browsers to validate so only one of them is required? i.e if telephone is filled, don't throw an error about mobile being empty and vice versa
Update 2020-06-21 (ES6):
Given that jQuery has become somewhat unfashionable in the JavaScript world and that ES6 provides some nice syntactic sugar, I have written a pure JS equivalent to the original answer:
document.addEventListener('DOMContentLoaded', function() {
const inputs = Array.from(
document.querySelectorAll('input[name=telephone], input[name=mobile]')
);
const inputListener = e => {
inputs
.filter(i => i !== e.target)
.forEach(i => (i.required = !e.target.value.length));
};
inputs.forEach(i => i.addEventListener('input', inputListener));
});
<form method="post">
Telephone:
<input type="tel" name="telephone" value="" required>
<br>Mobile:
<input type="tel" name="mobile" value="" required>
<br>
<input type="submit" value="Submit">
</form>
This uses the input event on both inputs, and when one is not empty it sets the required property of the other input to false.
Original Answer (jQuery):
I played around with some ideas and now have a working solution for this problem using jQuery:
jQuery(function ($) {
var $inputs = $('input[name=telephone],input[name=mobile]');
$inputs.on('input', function () {
// Set the required property of the other input to false if this input is not empty.
$inputs.not(this).prop('required', !$(this).val().length);
});
});
I've written a jQuery plugin wrapping the above JavaScript code so that it can be used on multiple groups of elements.
Based on Andy's answer, but I needed a checkbox implementation & came up with this.
what role(s) do you want?
<input type="checkbox" data-manyselect="roler" name="author" required>
<input type="checkbox" data-manyselect="roler" name="coder" required>
<input type="checkbox" data-manyselect="roler" name="teacher" required>
where will you work?
<input type="checkbox" data-manyselect="placement" name="library" required>
<input type="checkbox" data-manyselect="placement" name="home" required>
<input type="checkbox" data-manyselect="placement" name="office" required>
jQuery(function ($) {
// get anything with the data-manyselect
// you don't even have to name your group if only one group
var $group = $("[data-manyselect]");
$group.on('input', function () {
var group = $(this).data('manyselect');
// set required property of other inputs in group to false
var allInGroup = $('*[data-manyselect="'+group+'"]');
// Set the required property of the other input to false if this input is not empty.
var oneSet = true;
$(allInGroup).each(function(){
if ($(this).prop('checked'))
oneSet = false;
});
$(allInGroup).prop('required', oneSet)
});
});
Here for anyone else getting here by googling and wanting a quick solution for one of many checkboxes.
You would better do form data validation with Javascript anyway, because the HTML5 validation doesn't work in older browsers. Here is how:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Form Validation Phone Number</title>
</head>
<body>
<form name="myForm" action="data_handler.php">
<input type="tel" name="telephone">
<input type="tel" name="mobile">
<input type="button" value="Submit" onclick="validateAndSend()">
</form>
<script>
function validateAndSend() {
if (myForm.telephone.value == '' && myForm.mobile.value == '') {
alert('You have to enter at least one phone number.');
return false;
}
else {
myForm.submit();
}
}
</script>
</body>
</html>
.

For two text fields #Andy's answer is working awesome, but in case of more than two fields we can use something like this.
jQuery(function ($) {
var $inputs = $('input[name=phone],input[name=mobile],input[name=email]');
$inputs.on('input', function () {
var total = $('input[name=phone]').val().length + $('input[name=mobile]').val().length + $('input[name=email]').val().length;
$inputs.not(this).prop('required', !total);
});
});
I have created a basic HTML contact form using cgimail and everything works, but I can't get it to keep from redirecting somewhere after the form is submitted. I'm trying to instead use a bootstrap alert at the top of the page.
How do I get the form to submit, then keep it from redirecting?
here's the code:
<form method="post" action="/cgi-bin/cgiemail/forms/email.txt">
<fieldset>
<h2 id="contact-header">Contact</h2>
<label>Name:</label>
<input type="text" name="yourname" placeholder="" autofocus>
<label>Email Address:</label>
<input type="email" name="email" value="" placeholder="">
<label>Phone:</label>
<input type="tel" name="phone" value="" placeholder="">
<label>Message:</label>
<textarea name="message" rows="2"></textarea>
<br>
<button type="submit" id="formSubmit" class="btn">Send</button>
<input type="hidden" name="success" value="">
</fieldset>
</form>
Thanks,
Ryan
The "action" attribute in your form is telling it to send the browser over to that email.txt, which would then have control over whether or not to redirect you to another page. By default it would at least redirect you to the email.txt page for the post, but odds are cgi is doing extra stuff when posting to that page.
Using jQuery AJAX, you can do the following (this code skips error checking):
$('form').submit(function() {
var data = { };
data.yourname = $(this).find('input[name="yourname"]').val();
data.message = $(this).find('textarea[name="message"]').val();
// do the same as above for each form field.
$.post("/cgi-bin/cgiemail/forms/email.txt", data, function() {
//add the alert to the form.
$('body').prepend('div class="alert">Success!</div>');
});
return false;
});
You have two straight-forward choices. You can use jQuery and its forms plugin to turn this into an ajax operation or you can roll your own equivalent. It would look something like this (using jQuery):
$('form').submit(function() {
... get all values.
... ajax post the values to the server.
return false;
});
If you're using jQuery, then you could try cancelling the submit event. First give your form an id
HTML:
<form id="myform" ...
JavaScript:
$('#myform').on('submit', function(e) {
e.preventDefault();
$.ajax({
url: '/cgi-bin/cgiemail/forms/email.txt',
type: 'post',
data: $(this).serialize()
});
return false;
});
