I'm getting this fatal error message:
Fatal error: Can't use method return value in write context in C:\wamp\www\mySite\application\controllers\eventsManager.php on line 115
Could someone tell me what it means?
The line it refers to is this:
$this->session->set_flashdata('alert') = '<ul>' . validation_errors('<li>', '</li>') . '</ul>';
That line should be:
$this->session->set_flashdata('alert', '<ul>'.validation_errors('<li>','</li>').'</ul>');
From a quick google search, I have gathered that the empty() function may be the culprit. It isn't in your code but it may be in set_flashdata() somewhere. empty() can only check a variable, not the return value of a function. Assign validation_errors('<li>','</li>') to at temp variable and insert the temp var instead.
$this->session->set_flashdata('alert')doing? The error usually means you have to store value returned from a function before you can assign any values to it.
