  & lt ;? Php if ($ _GET ['id']> gt; = '1') {$ data_entry_id = $ _GET ['id']; $ Current_user_id = get_current_user_id (); $ Row_kids = $ wpdb- & gt; Query ("Select * from reg_children, where '% data_entry_id%' and UID = '$ current_user_id'" like kids;); If (! $ Rows_kids)! {$ Wpdb- & gt; Query ("INSERT ('', '$ data_entry_id', '$ current_user_id')" in reg_children VALUES); }}? & Gt;   
 Thank you in advance for your help.   
 
 
 you should  
  $ row_kids = $ wpdb-> gt; ; Query ("Select * from reg_children, where '% data_entry_id%' and UID = '$ current_user_id'" like kids;);   
 You've mesh with single quotes and make sure that $ wpdb has been declared globally.  
 And there should be a combined query  
  $ wpdb-> Query (include "reg_children in VALUES (zero, '$ data_entry_id', '$ current_user_id'));   
 And mainly if you should have the statement  
  if (empty ($ totalRows_kids)) {  
 Forgot to close the brace and make sure you defined $ totalRows_kids ... I think counting results from the selection query
