Hello,

I have created some custom fields for hotel classification, price range etc.

Hotel classification for instance needs to be entered as a number ranging from 1 to 5 in the backend but shown as a number of stars in the front-end.

What is the right hook to add a filter or action to add some replace functionality in my php-file?

I have searched the Codex documentation but could not find the right hook.

Best, Markus

Hi Markus,

I asked to the developers if there is a hook for this and how you can use it.

They’ll let us know asap.

Thanks

Hi Markus,

The hook name depends on the type of field used for the number and the HTML variable name used to name the custom field. If you provide wp-admin i will make you one example.

Thanks,

Hi Stiofan,

Thank you for looking into that topic.

One good example for a custom field is geodir_classification in wp_geodir_gd_place_detail. The values need to be entered as number ranging from 1 to 5 but need to be shown as a number of stars in the front-end e.g. ***** for a 5-star hotel.

I would like to implement something like:

add_filter(‘XXX_HOOK’,’ggp_geodir_classification’);
function ggp_geodir_classification( $classification ){
if($classification ==’5′)
$stars = str_replace(‘5′,'’,$classification);
elseif($classification ==’4′)
$stars = str_replace(‘4′,'’,$classification);
elseif($classification ==’3′)
$stars = str_replace(‘3′,'’,$classification);
elseif($classification ==’2′)
$stars = str_replace(‘2′,'’,$classification);
else
$stars = str_replace(‘1′,'’,$classification);
return $stars;
}

What would be the XXX_HOOK?

Thanks for the info i have added the following snippet to your site under “Code Snippets”
```
add_filter('geodir_custom_field_output_text','ggp_geodir_classification',15,3);
function ggp_geodir_classification( $html,$location,$cf){
 global $post;
 
 if($cf['name']!='geodir_classification'){return $html;} // if not the field we want then return standard
 
 $classification = $post->{$cf['htmlvar_name']};
 
 if($classification =='5')
 $html = str_replace('5','',$html);
 elseif($classification =='4')
 $html = str_replace('4','',$html);
 elseif($classification =='3')
 $html = str_replace('3','',$html);
 elseif($classification =='2')
 $html = str_replace('2','',$html);
 else
 $html = str_replace('1','',$html);
 return $html;
}
```
Thanks,
