# Displaying Errors

After validation you can use the same results object and use it to display the validation errors in your client side:

## Handlers:

```javascript
// store the validation results in the request collection
prc.validationResults = validate( obj );
```

## Views:

```markup
<-- Display all errors as a message box --->
#getInstance( "MessageBox@cbMessagebox" )
    .renderMessage( type="error", messageArray=prc.validationResults.getAllErrors() )#
```

If you want more control you can use the `hasErrors()` and iterate over the errors to display:

```javascript
<cfif prc.validationResults.hasErrors()>
    <ul>
    <cfloop array="#prc.validationResults.getErrors()#" index="thisError">
        <li>#thisError.getMessage()#</li>
    </cfloop>
    </ul>
</cfif>
```

You can even use the results object in your views to get specific field errors, message, etc.

## Functional Approach

You can also use the callbacks `onError() and onSuccess` to finalize the validation.  These are very common when using non only html apps but api apps.

```javascript
any function saveShared( event, rc, prc ){
		// validation
		validate(
			target      = rc,
			constraints = "sharedUser"
		).onError( function( results ){
			flash.put(
				"notice",
				results.getAllErrors().tostring()
			);
			return index( event, rc, prc );
		})
		.onSuccess( function( results ){
			flash.put( "User info validated!" );
			relocate( "main" );
		} );
	}
```

## Common Methods

The following are some common methods from the validation result object for dealing with errors:

* `getResultMetadata()`
* `getFieldErrors( [field] )`
* `getAllErrors( [field] )`
* `getAllErrorsAsJSON( [field] )`
* `getAllErrorsAsStruct( [field] )`
* `getErrorCount( [field] )`
* `hasErrors( [field] )`
* `getErrors()`
* `onError( consumer )`
* `onSuccess( consumer )`

The API Docs in the module (once installed) will give you the latest information about these methods and arguments.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://coldbox-validation.ortusbooks.com/v3.x-1/overview/displaying-errors.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
