html表格行为空时发生插入。如果任何输入字段有值allow to insert，则不要将空行插入数据库。我需要在哪里更改代码？如果表格数据行为空，则插入数据
PHP代码

for ($count = 0; $count < count($itemname); $count++) {
        $itemname_clean  = mysqli_real_escape_string($link, $itemname[$count]);
        $unit_clean      = (int) $unit[$count];
        $quantity_clean  = (int) $quantity[$count];
        $rate_clean      = $rate[$count];
        $totamount_clean = $totamount[$count];
        $checkvat_clean  = $checkvat[$count];
        if ($itemname_clean != '' || $unit_clean != '' || $quantity_clean != '' || $rate_clean != '' || $totamount_clean != '') {
            $query .= '
   //insert query goes here
        }
    }
