Codeigniter Form Validation Error Message Not Showing
up vote 4 down vote favorite 2 I want to make some custom error messages in my CodeIgniter forms. I've tried using $this->form_validation->set_message('is_unique[users.username]', 'The username is already taken'); However I can't get it working. Editing the form_validation_lang.php file is not good enough, as is_unique will be The username is already taken for usernames, and The e-mail is already registered for mails. How can I make this custom codeigniter form validation example error message? Here's a snippet from my code: $this->form_validation->set_message('is_unique[users.username]', 'The username is already taken'); // Check if username has changed if ($this->input->post('username') !== $user->username) { $this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[4]|max_length[20]|is_unique[users.username]'); } php forms codeigniter validation share|improve this question asked Jan 22 '13 at 14:15 Patrick Reck 4,16373065 1 check out the form validation example on the codeigniter documentation site.. ellislab.com/codeigniter/user-guide/libraries/… –MrFoh Jan 22 '13 at 14:26 The code example I posted is identical to the docs: $this->form_validation->set_message('required', 'Your custom message here'); –Patrick Reck Jan 22 '13 at 15:47 add a comment| 4 Answers 4 active oldest votes up vote 10 down vote accepted Right way of doing this is by passing a string format $this->form_validation->set_message('is_unique', 'The %s is already taken'); So, then only we can able to get message like "This Username is already taken" or "This Email is already taken". share|improve this answer answered Mar 17 '14 at 17:45 Balakrishnan 65021030 add a comment| up vote 1 down vote This worked for me $this->form_validation->set_message('is_unique', 'The username is already taken'); share|improve this answer answered Apr 19 '13 at 7:57 Devendra Verma 370318 add a comment| up vote 1 down vote It's better you use like this: $this->form_validation->set_message('is_un

You fill it in and error message submit it. If you submitted something invalid, or perhaps missed a required item, the form is redisplayed containing your data along with an error message describing the problem. This process continues until you have submitted a valid form. On the receiving end, the script must: Check for required data. Verify that the data is of the correct type, and meets the correct criteria. For codeigniter form validation example, if a username is submitted it must be validated to contain only permitted characters. It must be of a minimum length, and not exceed a maximum length. The username can't be someone else's existing username, or perhaps even a reserved word. Etc. Sanitize the data for security. Pre-format the data if needed (Does the data need to be trimmed? HTML encoded? Etc.) Prep the data for insertion in the database. Although there is nothing terribly complex about the above process, it usually requires a significant amount of code, and to display error messages, various control structures are usually placed within the form HTML. Form validation, while simple to create, is generally very messy and tedious to implement. Form Validation Tutorial What follows is a "hands on" tutorial for implementing CodeIgniters Form Validation. In order to implement form validation you'll need three things: A View file containing a form. A View file containing a "success" message to be displayed upon successful submission. A controller function to receive and process the submitted data. Let's create those three things, using a member sign-up form as the example. The Form Using
MY_Form_validation extends CI_Form_validation { private $_custom_field_errors = array(); public function _execute($row, $rules, $postdata = NULL, $cycles = 0) { // Execute the parent method from CI_Form_validation. parent::_execute($row, $rules, $postdata, $cycles); // Override any error messages for the current field. if (isset($this->_error_array[$row['field']]) && isset($this->_custom_field_errors[$row['field']])) { $message = str_replace( '%s', !empty($row['label']) ? $row['label'] : $row['field'], $this->_custom_field_errors[$row['field']]); $this->_error_array[$row['field']] = $message; $this->_field_data[$row['field']]['error'] = $message; } } public function set_rules($field, $label = '', $rules = '', $message = '') { $rules = parent::set_rules($field, $label, $rules); if (!empty($message)) { $this->_custom_field_errors[$field] = $message; } return $rules; } } ?> This entry was tagged codeigniter, php.
