           ?>    <form action="cumpar.php"  method="post">
<td><input type="text" name="cantitate[]" value=" " size="1"/></td></tr>
<input type="hidden" name="Denumire_produs[]" value="<?php echo $row['Denumire_produs'];?>"/>

 for($i=0;$i<$limit;$i++){

    $queryi="insert into livrari_luni
                (user_id,
                id_programare,
                id_produs,
                denumire_produs,
                Pret,

                '". $id_produs[$i] ."',
                '". $denumire[$i] . "',
                 '". $pret[$i] . "',                
                '". $cantitate [$i] ."')";
                $resulti = mysql_query($queryi)

Test for the condition you want to eliminate in your loop.

for($i=0;$i<$limit;$i++){
    if(intval($cantitate[$i]) < 1) continue;   // skip to next entry in the array;
    $queryi="insert into livrari_luni
...

I use

if($cantitate[$i])> 1)

and it seem to be ok this way to;

[pritaeas]

This will skip values of 1 too, so either change it to < 1 or >= 1

[liamfriel]

Any variables with the values false/0/NULL/"" are considered to execute false in PHP

#execcute if $cantitate[$i] is not null
if($cantitate[$i]){
  //this part of the array is not NULL.....
}

Would also be fine.
