approach to data validation, let's describe the ideal scenario: A form is displayed. You fill it in and 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 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. codeigniter form validation error message not showing 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 a text editor, create a form called myform.php. In it, place this code and save it to your applications/views/ folder:

EDIT : validation rules: private $validation_rules = array( array( 'field' => 'username', 'label' => 'Username', 'rules' => 'trim|required|callback__check_valid_username|min_length[6]|max_length[20]|xss_clean' ), array( 'field' => 'password', 'label' => 'Password', 'rules' => 'trim|required|min_length[6]|max_length[32]' ), ); php codeigniter share|improve this question edited Dec 9 '11 at 14:46 asked Dec 8 '11 at 10:22 fxuser 1,939840103 How you set your validation rule(s)? Those additional information will necessary. set_message method allow you to set your own error messages on the fly. But one thing you should notice, that the key name has to match the function name that it corresponds to. –toopay Dec 8 '11 at 14:35 what im trying to do is to show an extra error message when the user enter incorrect login details. –fxuser Dec 8 '11 at 15:08 Additional information which you need to provide is : (i repeat again) how you set your validation rule(s)? Did you use custom callback function? required? unique? –toopay Dec 9 '1
CodeIgniter Form Validation - Setting Rules, Setting Error Messages and Repopulating Form by Nagarajan 10/12/2014 | 8:16 0 Posted in CodeIgniter, Web Technology Hello Readers, I would like to write a blog on http://www.geeks.gallery/codeigniter-form-validation-setting-rules-setting-message-and-repopulating-form/ CodeIgniter form validation. Form validation on server side is very important in order to avoid entering some random values and also client side validation such as javascript validation is easily breakable.

This is easy to implement. But user can easily bye pass it by right clicking on the webpage, opening console and can edit HTML contents, user can remove the required from code and can submit the form with empty value. So it is necessary to validate form in server side, which cannot be bye passed. codeigniter form validation Consider you are about to validate a user Login form. You
