A recursive function that takes a validation error array and return a string with all the different errors concatenated into a formatted string
Further to my previous posting
This function will walk the validationErrors array and return the error messages.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | function formatValidationErrors($validationErrors = [], $errorMessage = null){ // get Validation errors and append them into a string foreach ($validationErrors as $key => $value) { if (is_array($value)) { $errorMessage = formatValidationErrors($value, $errorMessage); } else { if ($errorMessage) { $errorMessage .= sprintf(". <strong>%s: </strong>", $value); } else { $errorMessage = sprintf("<strong>%s</strong>", $value); } } } return $errorMessage;} |
Calling the code from your controller
1 2 | // app/Controller/CartonController.php$errorText = $this->Carton->formatValidationErrors($this->Carton->validationErrors); |
