Symfony2 - Getting All Errors From a Form in a Controller

Recently I was working on an API call which uses a form to validate the data you are passing in. I ran into the issue of getting all the errors for a form in Symfony2 is not as straight forward as you would think. At first I tried $form->getErrors() and then looped through the errors. That didn’t get all of them. After looking around I found:

<?php
    public function getAllErrors($children, $template = true) {
    	$this->getAllFormErrors($children);
    	return $this->allErrors;
    }
   
    
    private function getAllFormErrors($children, $template = true) {
    	foreach ($children as $child) {
    		if ($child->hasErrors()) {
    			$vars = $child->createView()->getVars();
    			$errors = $child->getErrors();
    			foreach ($errors as $error) {
    				$this->allErrors[$vars["name"]][] = $this->convertFormErrorObjToString($error);
    			}
    		}
    
    		if ($child->hasChildren()) {
    			$this->getAllErrors($child);
    		}
    	}
    }
    

    
    private function convertFormErrorObjToString($error) {
    	$errorMessageTemplate = $error->getMessageTemplate();
    	foreach ($error->getMessageParameters() as $key => $value) {
    		$errorMessageTemplate = str_replace($key, $value, $errorMessageTemplate);
    	}
    	return $errorMessageTemplate;
    }

This works really well for any errors which are bound to a field. However it will not catch global errors such as a unique validator. It should probably be renamed from getAllErrors(). In order to get those you need to also loop through $form->getErrors(). This was returning the global errors only for me. Here is my code in the end:

<?php
        foreach($form->getErrors() as $e)
            $errors[]=$translator->trans($this->convertFormErrorObjToString($e), array(), 'validators');
        
        
        foreach($this->getAllErrors($children) as $key=>$error)
            $errors[]=$key.': '.$translator->trans($error[0], array(), 'validators');

There may be a better way, just wanted to shoot this out as not many people had good solutions on it.

Bonus: If you are using the translator service on validators and you get an error which is the ‘validators’ translation files, make sure you use the proper domain, ie: $translator->trans(‘key’,array(),‘validators’).
