Hi All

Basically I have 4 fields in my database

image2, image3, image4, image5

I have an image uploader to upload the files but I need what I need is if image2 is empty put in image3, if image3 is empty put in image4

so far I have this


//so first is the query to find the right row which gives the variable $row

//now here is what im doing

if($row['image2']!==""){
 //run this code
}

elseif($row['image3']!==""){
//run this code
}

elseif($row['image4']!==""){
//run this code
}

elseif($row['image5']!==""){
//run this code
}


Now the problem I'm having is the code that is always executing is the first one of $row['image2']

even if image2 has a value in the database it still runs that code and over writes the field in the database. It never moves on to field 3 or 4.  Can someone please tell me if I've done something wrong.


I'm not storing the image in the database just the name.

Thanks

Danny

I'm making a connection to Active Directory using ADODB connection. I can read almost everything from this but some outputs are in an Octet format.
For example objectSID is giving me only a ?.
Is there somebody that knows how to read or convert this?

I've found a converter function in ASP maybe someone can translate this to PHP?

Code: [Select]
TXT_ObjectGUID = HexStrToDecStr(OctetToHexStr(objRecordSet.fields("objectSID")))

Function OctetToHexStr(arrbytOctet)
' Function to convert OctetString (byte array) to Hex string.
Dim k
OctetToHexStr = ""
For k = 1 To Lenb(arrbytOctet)
OctetToHexStr = OctetToHexStr _
& Right("0" & Hex(Ascb(Midb(arrbytOctet, k, 1))), 2)
Next
End Function

Function HexStrToDecStr(strSid)
' Function to convert hex Sid to decimal (SDDL) Sid.
Dim arrbytSid, lngTemp, j

ReDim arrbytSid(Len(strSid)/2 - 1)
For j = 0 To UBound(arrbytSid)
arrbytSid(j) = CInt("&H" & Mid(strSid, 2*j + 1, 2))
Next

HexStrToDecStr = "S-" & arrbytSid(0) & "-" _
& arrbytSid(1) & "-" & arrbytSid(8)

lngTemp = arrbytSid(15)
lngTemp = lngTemp * 256 + arrbytSid(14)
lngTemp = lngTemp * 256 + arrbytSid(13)
lngTemp = lngTemp * 256 + arrbytSid(12)

HexStrToDecStr = HexStrToDecStr & "-" & CStr(lngTemp)

lngTemp = arrbytSid(19)
lngTemp = lngTemp * 256 + arrbytSid(18)
lngTemp = lngTemp * 256 + arrbytSid(17)
lngTemp = lngTemp * 256 + arrbytSid(16)

HexStrToDecStr = HexStrToDecStr & "-" & CStr(lngTemp)

lngTemp = arrbytSid(23)
lngTemp = lngTemp * 256 + arrbytSid(22)
lngTemp = lngTemp * 256 + arrbytSid(21)
lngTemp = lngTemp * 256 + arrbytSid(20)

HexStrToDecStr = HexStrToDecStr & "-" & CStr(lngTemp)

lngTemp = arrbytSid(25)
lngTemp = lngTemp * 256 + arrbytSid(24)

HexStrToDecStr = HexStrToDecStr & "-" & CStr(lngTemp)

End Function

Hi, I'm trying to force 2 decimal places with the following function but it 's not working.  Any suggestions? 

Code: [Select]
function ShippingCost() {
$shippingCost = 4.00;
    number_format($shippingCost,2);
return $shippingCost;
}
