Version: Reporter: Brian Litzinger —
I haven’t tracked down the cause of this yet but while making a new fieldtype I encountered this error:
Error: Call to a member function accepts_content_type() on boolean in /var/www/html/system/ee/EllisLab/Addons/grid/libraries/Grid_lib.php on line 665

12 4.4692 10911968 Grid_lib->get_grid_fieldtypes( ) .../ft.grid.php:460I tracked it down to the setup_handler method returning false, so its trying to call the accepts_content_type method on a boolean. Either the setup_handler shouldn’t return a boolean or an object, or before trying to call accepts_content_type it should check to make sure $fieldtype is a valid field object, and if not, throw a helpful error message.
foreach ($fieldtypes as $field_short_name => $field_name)
{
$fieldtype = $ft_api->setup_handler($field_short_name, TRUE);
// Check to see if the fieldtype accepts Grid as a content type;
// also, temporarily exlcude Relationships for content types
// other than channel
if ( ! $fieldtype->accepts_content_type('grid') ||
($this->content_type != 'channel' && $field_short_name == 'relationship'))
{
unset($fieldtypes[$field_short_name], $compatibility[$field_short_name]);
}
