how to execute multiple query. I just can execute one query

[urtrivedi]

1) You must concate $word. In your code u assiging new query

$word .= "INSERT INTO relation_mu_and_unit (id_drug, id_unit, priority, value, harga1, harga2, harga3, last_edit) VALUES ( $id_drug,$id_unit, $i, $value, $harga_1, $harga_2, $harga_3, NOW() );";

2) mysqli expects connection first then query, make sure you create mysqli connection.

mysqli_mutli_query($conni, $word) ;

3) for multiquery you must keep mysqli_mutli_query($conni,$word) outside for loop

      $word .= "INSERT INTO relation_mu_and_unit (id_drug, id_unit, priority, value, harga1, harga2, harga3, last_edit) VALUES  ( $id_drug,$id_unit, $i, $value, $harga_1, $harga_2, $harga_3, NOW() );";
 } // for loops ends here                                                                          
 mysqli_multi_query($conni,$word);
