richtext
Content
[...]
```php$model->scenario = "abc";
```
... but had no **rule** defined yet. I wanted to implement the rule later, but I didnt know that when you set a scenario to your model it **must** be used in method rules() or defined in method scenarios(). So take this into consideration. I expected that when the scenario has no rules it will just be skipped or deleted.
**Richtext / wysiwyg HTML editor - Summernote**
---
If you want to allow user to enter html-formatted text, you need to use some HTML wysiwyg editor, because ordinary TextArea can only work with plain text. It seems to me that [Summernote](https://summernote.org/getting-started/#simple-example) is the simplest addon available:
```javascript
// Add following code to file layouts/main.php ..
// But make sure jquery is already loaded !!
// Read above in chapter "Adding a google-like calendar"
<!-- include summernote css/js -->
<link href="http://cdnjs.cloudflare.com/ajax/libs/summernote/0.8.12/summernote.css" rel="stylesheet">
<script src="http://cdnjs.cloudflare.com/ajax/libs/summernote/0.8.12/summernote.js"></script>
// And then in any view you can use this code:
<script>
$(document).ready(function() {
$('#summernote1').summernote();
$('#summernote2').summernote();
});
</script>
<div id="summernote1">Hello Summernote</div>
<form method="post">
<textarea id="summernote2" name="editordata"></textarea>
</form>
```
in this tutorial I showed how to save Contacts inqueries into database. If you want to use this richtech editor in this section, open view contast/\_form.php and just add this JS code:
```javascript
<script>
$(document).ready(function() {
$('#contact-body').summernote();
});
</script>
```
It will be saved to DB as HTML code. But this might be also a source of problems, because user can inject some dangerous HTML code. So keep this in mind.
Now you will also have to modify view contact/view.php like this in order to see nice formatted text:
```php
DetailView::widget([
'model' => $model,
'attributes' => [
// ...
'body:html', // html
],
])
```
