Listing tab order code snippet error

Hi,

I read the tutorial on changing the order of the tabs in the listing but I’m getting errors when I try to change the order – probably don’t know what i’m doing properly.

I tried the code below:

// this is the snippet that adds the filter, calling the function below.
add_filter(‘geodir_detail_page_tab_list_extend’, ‘geodir_detail_page_tab_list_extend’) ;

// this is the function that does the re-ordering that we call with the add filter snippet above.
function geodir_detail_page_tab_list_extend($tab_array)
{

// here you can modify the array and re-arrange tabs as you wish, you can create a completely new array too.

// this is the review tab, by default is the 7th, but here we moved it to position 1.
if(isset($tab_array[‘reviews’])){
$new_tab_array[‘reviews’] = $tab_array[‘reviews’];// set in new array
// IMPORTANT the following code tells GeoDirectory that this is the new default active tab
$new_tab_array[‘reviews’][‘is_active_tab’]=’2′;
unset($tab_array[‘reviews’]);//unset in old one
}

// this is the post profile tab, by default is the 1st
if(isset($tab_array[‘post_profile’])){
$new_tab_array[‘post_profile’] = $tab_array[‘post_profile’]; // set in new array
// IMPORTANT the following code tells GeoDirectory that this is no longer the default active tab
$new_tab_array[‘post_profile’][‘is_active_tab’]=’3′;
unset($tab_array[‘post_profile’]);//unset in old one
}

// this is the post info tab (optional for custom fields), by default, if available, is the 2nd.
if(isset($tab_array[‘post_info’])){
$new_tab_array[‘post_info’] = $tab_array[‘post_info’];// set in new array
unset($tab_array[‘post_info’]);//unset in old one
}
// this is the images tab, by default is the 3rd
if(isset($tab_array[‘post_images’])){
$new_tab_array[‘post_images’] = $tab_array[‘post_images’];// set in new array
unset($tab_array[‘post_images’]);//unset in old one
}

// this is the video tab, appears only if there are videos and by default is the 4th
if(isset($tab_array[‘post_video’])){
$new_tab_array[‘post_video’] = $tab_array[‘post_video’];// set in new array
unset($tab_array[‘post_video’]);//unset in old one
}

// this is the speacial offer tab, appears only if there are special offers and by default is the 5th
if(isset($tab_array[‘special_offers’])){
$new_tab_array[‘special_offers’] = $tab_array[‘special_offers’];// set in new array
unset($tab_array[‘special_offers’]);//unset in old one
}

// this is the map tab, by default is the 6th
if(isset($tab_array[‘post_map’])){
$new_tab_array[‘post_map’] = $tab_array[‘post_map’];// set in new array
unset($tab_array[‘post_map’]);//unset in old one
}

// this is the related listing tab, it is optional and by default is the 8th
if(isset($tab_array[‘related_listing’])){
$new_tab_array[‘related_listing’] = $tab_array[‘related_listing’];// set in new array
unset($tab_array[‘related_listing’]);//unset in old one
}

// now we set any remaining tabs that have not been assigned an order
foreach($tab_array as $key=>$tab){
$new_tab_array[$key]=$tab;
}

return $new_tab_array ;
}

I just need it in the following order:

1. map
2. reviews
3. profile
4. post info
5+ any for now (undecided)

I put it in the functions child theme. If you can clearly show me how I can change the code for the order above that would be smashing
Thanks
