List PHP events - hide some rows, custom filter

[urbido]

Hi, I have custom input in filters, which I pass on change in filter array. Then in PHP events (onLoadData) I take that custom input, process some data and change some rows. It works fine, but I would like to "hide/delete unchanged rows". I tried to do in in onPreLoadData, but anytime I do $model->someMethod, I get 500 error. Also, I tried in "onLoadData", in foreach($rows as $row) unset $row, set $row = null, but its still visible in list.

What is proper way to take list filter params, do some custom-functions and then remove certain rows from list data, according to input filter params and custom-function's result?

In both onPreLoadData and onLoadData code such as in the Wiki examples should work.
Which PHP version are you running?
Don't you get detailed info for the 500 error with error reporting and debug on?
Don't forget, you can always var_dump() or print_r() variables followed by an "exit;" in your code to see what you're having.
Double-/triple-check for syntax errors, of course.

Guess more can't be said without knowing your exact code.

You didn't get me. I tried several ways to hide rows. Is there any way to hide/remove rows from list using php_events?
