Re: empty and isset

ok i dont know if this will help at all since the code that doesnt work wont fit in the message (got error saying i cant send that much all at once) this is what i got out of var_dump.. first set of variables: $member[Areacode1]=string(3)"123" 123 $member[Exchange1]=string(3)"123"123 $member[Number1]=string(4)"1234"1234 those variables im not worried about because they are required in the form. the next ones i want to exclude from the list all together if string()==0 on all 3 variables.. here is the var dumb from them: $member[AreaCode2]string(0)"" $member[Exchange2]string(0)"" $member[Number2]string(0)"" here is the seudo code for what i need to do: if $member[AreaCode] & $member[Exchange2] & $member[Number2] is empty, null =="" or has string(0) in it { //exclude vars from list alltogether } any other conditions{ //print the vars in the list } ----- Original Message ----- From: "John W.
