Oscommerce Common Issues/ Bugs: 3

atal error: Call to a member function add_current_page() on a non-object in /home/xx/xxx/includes/application_top.php on line 312

This is another of the common issues I encounter almost on every new instance I work on. Issue resolution is very simple. Following the steps as below:

1. open includes/application_top.php
2. find the section of code

// navigation history
if (tep_session_is_registered('navigation')) {
if (PHP_VERSION < broken_navigation =" $navigation;" navigation =" new">unserialize($broken_navigation);
}
} else {
tep_session_register('navigation');
$navigation = new navigationHistory;
}
$navigation->add_current_page();

3. Replace the section with the following segment of code:

// navigation history
if (tep_session_is_registered('navigation')) {
if (PHP_VERSION < broken_navigation =" $navigation;" navigation =" new">unserialize($broken_navigation);
} else {
$navigation = new navigationHistory;
}
} else {
tep_session_register('navigation');
$navigation = new navigationHistory;
}
$navigation->add_current_page();
