I need to display user friendly error message in the view I am in, and wondering what will be the best solution. I can display and error page using error controller but this is not what i want to achieve. I need to handle all custom error messages in any model and display an error in the view you are in. For example:
I am in "user" controller. When creating new user, the PHP model code checks if same user name exist, if exist I want to display a message in the view or maybe have something like this in header: echo $error; which display any error message I have set to be displayed from any model if occurred.
Example error message in model:
if ($p0 > 0) {
$IsValid = false;
log::LOG_USER_ERROR("This user already exist!", $username);
exit("This user already exist! </br> ");
}
This code write the error in a log file successfully, however how do I display the error message in the same view I am in? exit() displays the message in a blank page. I need to display it as block in red in the same view and design.
exit() terminates the current script, so the code for your View is not executed.
Instead, part of your View should be an area to display messages. Then you can put the error message in a variable (probably an array of messages) that the View displays to the user in that area.
