Question

How can I write a condition such that if the row wasn’t found to then do something?

My code

$resultt = mysql_query("SELECT * FROM objednavky WHERE kdo = '$kdo' and kdy = '$the_rday'");
                        while ($roww = mysql_fetch_array($resultt)) {

                            echo "<form method='post' action=''>
                                  <label for='obb1'>Menu #1&emsp;</label>
                                  <input type='text' name='obb1' value='$roww[3]' size='4'><br>
                                  <label for='obb1'>Menu #2&emsp;</label>
                                  <input type='text' name='obb2' value='' size='4'><br>
                                  <label for='obb1'>Menu #3&emsp;</label>
                                  <input type='text' name='obb3' value='' size='4'><br>
                                  <input type='submit' value='objednat'></form>";


                        }

And I want to continue like this

   ...} else {
echo " no match ";
}

Thank you so much for help.

In this case you can use mysql_num_rows()

$resultt = mysql_query("SELECT * FROM objednavky WHERE kdo = '$kdo' and kdy = '$the_rday'");


   if(mysql_num_rows($resultt)<1){
   echo "not found";
   }else{

     while(...)

       }
