I am trying create a wrapper directive over select and I am trying to assign the 'name 'attribute to the select
directive
<form name=myform>
<selectformfield label="Select Orders" id="id_1" name="orderselection"
selectedval="obj.order" options="Orders" />
</form>
I have my directive defined as
mainApp
.directive(
'selectformfield',
function() {
return {
restrict : 'E',
transclude : true,
scope : {
label : '@',
id : '@',
selectedval : '=',
options : '=',
name: '='
},
template : "<select class='form-control' ng-model='selectedval' name='{{name}}' ng-options='item as item.name for item in options' required><option value=''>-- select --</option></select>"
};
});
I am trying to access the select's name attribute through myform in the controller something like console.log($scope.myForm.orderselection) and I get undefined
If I hardcode the name in the directive then I am able to access the attribute console.log($scope.myForm.orderselection)
I am missing anything here. Do I have to do any post compile or something ?

The ng-bind directive tells AngularJS to replace the content of an HTML element with the value of a given variable, or expression. If the value of the given variable, or expression, changes, the content of the specified HTML element will be changed as well.
Pre-linking function Executed before the child elements are linked. Not safe to do DOM transformation since the compiler linking function will fail to locate the correct elements for linking. Post-linking function Executed after the child elements are linked.
Compiles an HTML string or DOM into a template and produces a template function, which can then be used to link scope and the template together.
A - ng-bind directive binds the AngularJS Application data to HTML tags.
Khanh TO is correct in that you need to setup your name correctly when trying to access to through your isolated scope. Here is a working example of what I believe you are trying to accomplish. I've added comments to the code where I've changed what you had.

Javascript:
var app = angular.module('plunker', [])
.controller('MainCtrl', function ($scope, $log) {
$scope.model = {
person: {
name: 'World'
},
people: [{
name: 'Bob'
}, {
name: 'Harry'
}, {
name: 'World'
}]
};
})
.directive('selectformfield', function ($compile) {
return {
restrict: 'E',
replace: true, // Probably want replace instead of transclude
scope: {
label: '@',
id: '@',
selectedval: '=',
options: '=',
name: '@' // Change name to read the literal value of the attr
},
// change name='{{ name }}' to be ng-attr-name='{{ name }}' to support interpolation
template: "<select class='form-control' ng-model='selectedval' ng-attr-name='{{name}}' ng-options='item as item.name for item in options' required><option value=''>-- select --</option></select>"
};
});
HTML:
<body ng-controller="MainCtrl">
<p>Hello {{ model.person.name}}!</p>
<form name='myForm'>
<label for='orderselection'>Say hello to: </label>
<selectformfield label="Select Orders" id="id_1" name="orderselection"
selectedval="model.person" options="model.people"></selectformfield>
<p ng-class='{valid: myForm.$valid, invalid: myForm.$invalid }'>The form is valid: {{ myForm.$valid }}</p>
<p ng-class='{valid: myForm.orderselection.$valid, invalid: myForm.orderselection.$invalid }'>The people select field is valid: {{ myForm.orderselection.$valid }}</p>
</form>
</body>
CSS:
.valid {
color: green;
}
.invalid {
color: red;
}
