So, the entry is valid only if all three are non-blank?
In which case:
if ($skill!='' && $skys[$key]!='' && $slus[$key] !='')
{
// row is valid -- do stuff
}
else
{
// entry has at least one value blank -- issue error
}
If you prefer to have the error path come first, simply apply deMorgan's
laws to the Boolean expression, to get:
if ($skills=='' || $skys[$key]=='' || $slus[$key]=='')
{
// entry has at least one value blank -- issue error
}
else
{
// row is valid -- do stuff
}
Cheers!
