AbydosGater Posted October 9, 2006 Share Posted October 9, 2006 Hey, Ive been setting up a user managment system,And i have a page that allows users to edit their info, as you would,But after letting them fill the form, i stored their new information in variables! and now i want to make sure that nothing they entered is NULL or empty![quote] //Check If The Updates Are Legal!if ($newusername !== NULL || $newpassword !== NULL || $newemail !== NULL) {$doupdates = "TRUE";} else {$doupdates = "FALSE";}[/quote]So if none of them are NULL, it will do the updates, else dont do them,But this isnt working because later down the script i have...[quote]if ($doupdates == "TRUE") {echo "Do Update: TRUE";} elseif ($doupdates == "FALSE") {echo "<font color='#FF0000'><center><b>Please Note:<br>There Has Been An Error In The Information You Entered!<br>Please Go Back And Try Again!</b></center></font>";}[/quote]I replaced my sql updates with an echo, just for small topic... but when i run the script, and i leave one or all of the form fields.. I just get The Do Update True, so what have i done wrong??Thanks Quote Link to comment Share on other sites More sharing options...
Orio Posted October 9, 2006 Share Posted October 9, 2006 You if statement is wrong (($doupdates == "TRUE")).You are checking if $doupdates is the string "TRUE".You can either do-if($doupdates)orif($doupdates === TRUE)Same goes for the false, if($doupdates === FALSE) or if(!$doupdates).Orio.

sanfly Posted October 9, 2006 Share Posted October 9, 2006 Try this[code=php:0]//Check If The Updates Are Legal!if ($newusername && $newpassword && $newemail) { $doupdates = true;} else { $doupdates = false;}if ($doupdates === true) { echo "Do Update: TRUE";} elseif ($doupdates === false) { echo "<font color='#FF0000'><center>Please Note: There Has Been An Error In The Information You Entered! Please Go Back And Try Again!</center></font>";}[/code]EDIT: changed the "||" (or) to "&&" (and) > I assume you want all to be entered, not just any one or more of them, change back if im wrong there Quote Link to comment Share on other sites More sharing options...
AbydosGater Posted October 9, 2006 Author Share Posted October 9, 2006 Ok i Changed it to...[quote]if ($doupdates === TRUE) {echo "Do Update: TRUE";} elseif ($doupdates === FALSE) {echo "<font color='#FF0000'><center><b>Please Note:<br>There Has Been An Error In The Information You Entered!<br>Please Go Back And Try Again!</b></center></font>";}[/quote]But now i get nothing,, no echos :PEDIT:Hey Sanfly..Thanks, I know that the vars ARE set! i set them from my forms! i know there is a value, i want to check if the value is null, or if it actually has a value!?

sanfly Posted October 9, 2006 Share Posted October 9, 2006 [quote author=AbydosGater link=topic=110999.msg449515#msg449515 date=1160429115]Hey Sanfly..Thanks, I know that the vars ARE set! i set them from my forms! i know there is a value, i want to check if the value is null, or if it actually has a value!?[/quote]If the variables are empty, they will return false (or NULL), if there is a value, it returns true. So, eitherif($somevariable){ echo "YAY";}elseif(!$somevariable){ echo "Bummer, its empty/null";}orif(!empty($somevariable)){ echo "YAY";}elseif(empty($somevariable)){ echo "Bummer its empty/null";}should return the same thing in most cases Quote Link to comment Share on other sites More sharing options...
