RE: [PHP] if(($mydata->address

[snip] if( ($mydata->address != "") and ($mydata->addresspublic == "yes") ) { } But in other combinations, they work? if($mydata->address != ""){} or if($mydata->addresspublic == "yes"){} So what new lesson am I to learn now? :) [/snip] Always put the value first in case you accidentally try an assignment operator. Now, on to your code...(with my recommendations) if(("" != $mydata->address) && ("yes" == $mydata->addresspublic)){ ...stuff... } if(("" != $mydata->address) || ("yes" == $mydata->addresspublic)){ ...stuff... } Those should work. Now, why do I recommend the value first? Easy. Consider... if($mydata->foo = "") // always true, $mydata->foo is now equal to blank If I do this... if("" = $mydata->foo) // an error is thrown. If I come back in and finish the comparison operator (which I needed to know was broken) it fixes the conditional statement at this point.
