Submit content of div in database on button click - php

Question

I have a WYSIWYG tool where I can create a content. At the bottom, I have a form where I can submit a value (from an input text) to a database. That works fine. Now, I am trying to submit the content that has been created in the WYSIWYG in the database.
I am thinking of using a value in the input as shown below:
<input name="videoLink" type="text" value="John" required/>
and use javascript to make the value dynamic. But there must be an easier way. To make the form submit the content of a div instead of having to type anything in the input box.
My code is shown below:
angular.module("textAngularTest", ['textAngular']);
function wysiwygeditor($scope) {
$scope.orightml = '<h2>Put Your Text Here</h2>';
$scope.htmlcontent = $scope.orightml;
$scope.disabled = false;
};
.ta-editor {
min-height: 80px;
height: auto;
overflow: auto;
font-family: inherit;
font-size: 100%;
}

<div ng-app="textAngularTest" ng-controller="wysiwygeditor" class="container app">
<h3>WYSIWYG Editor</h3>
<div text-angular="text-angular" name="htmlcontent" ng-model="htmlcontent" ta-disabled='disabled'></div>
<!--<h3>Raw HTML in a text area</h3>
<textarea ng-model="htmlcontent" style="width: 100%"></textarea>-->
<h3>Preview</h3>
<div ng-bind-html="htmlcontent"></div>
<!--<h3>Bound with ta-bind, our internal html-binding directive</h3>
<div ta-bind="text" ng-model="htmlcontent" ta-readonly='disabled'></div>-->
<button type="button" ng-click="htmlcontent = orightml">Reset</button>
<form action="Insert.php" method='POST' enctype='multipart/form-data'>
<label><input name="videoLink" type="text" required/></label>
<input id="button" type="submit" name="log">
</form>
</div>

Use placeholder instead of value.
Set value =" " but the placeholder="Put text here" ... otherwise you could get a lot of Johns.. I presume that's what you want to avoid? I don't think you can avoid php/ passing values to php from html [using javascript] to enter values into a database.
Your form isn't that big. You don't need that amount of js unless your site is using angular/is included in all pages of the CMS. So if the question is really how to pass variables to php with minimal javascript, then comment.
You should still use placeholder instead of value. Otherwise if people don't change the text / maybe just press enter/submit.. your required error message won't fire. That's a lot of Johns in the db! :)
Hope this helps
