12. Form Validation<br />
CodeIgniter<br />
Validation is an important process while building web application. It ensures that the<br />
data that we are getting is proper and valid to store or process. CodeIgniter has made<br />
this task very easy. Let us understand this process with a simple example.<br />
Example<br />
Create a view file myform.php and save the below code it in<br />
application/views/myform.php. This page will display form where user can submit<br />
his name and we will validate this page to ensure that it should not be empty while<br />
submitting.<br />
<br />
<br />
My Form<br />
<br />
<br />
<br />
<br />
<br />
Name<br />
<br />
<br />
<br />
<br />
<br />
Create a view file formsuccess.php and save it in<br />
application/views/formsuccess.php. This page will be displayed if the form is<br />
validated successfully.<br />
