Hi Guys,
For some strange reason my class doesn't seem to want to initialize. This exact script works on my website currently, but is giving me a problem on my local development pc. Not quite sure what's wrong. This is a custom wordpress theme so its split up funky. I keep getting this error Fatal error: Call to a member function display_pages() on a non-object.
This is inside my page template.
PHP Code:
include_once( LP_CLASSES_DIR . '/pagination-class.php');
/* Get the records */
$drawing_count = HistData_Model::total_drawing_dates();
/* Define pagination */
$pages = new Pagination;
$pages->items_total = $drawing_count[0]['count(*)'];
$pages->mid_range = 7;
$pages->paginate();
echo $pages->display_pages();
echo $pages->display_items_per_page();
echo $pages->display_jump_menu();
foreach($drawings_array as $new_drawing):
echo $new_drawing; //This comes from further up and populates fine when you print array out.
endforeach;
echo "<br />";
echo $pages->display_pages();
this is my pagination class
PHP Code:
