I'm the lucky owner of the SMS plugin, but I just want to show it to the listing owner. I have already arranged that only logged in users can see the SMS payment method, but I would like to add the owner id from the listing.
If you can help me, it will be greatly appreciated.

my code now is:

<?php if(function_exists('sp_buttons')) if(osc_is_web_user_logged_in()) { { echo sp_buttons( osc_item_id() ); } ?>
<?php } ?>

line 484 i did:

<?php if(function_exists('sp_buttons'))  if(osc_item_user_id() > 0 && osc_item_user_id() == osc_logged_user_id()) {  { { echo sp_buttons( osc_item_id() ); } ?>
<?php } ?>
  <?php ;  } ?>

This is correct code:
<?php 
  if(function_exists('sp_buttons')) {
    if(osc_item_user_id() > 0 && osc_item_user_id() == osc_logged_user_id()) { 
      echo sp_buttons( osc_item_id() ); 
    } 
  }
?>


Added and works fine... thank you for support.
