Sorry to bother you guys again, but I can't get this to function properly and I can't see where the error is coming from. function ModifyCalc($sum, $ModType, $ModValue, $OptModType, $OptModValue){ $NewSum = 0; if ($ModType >= 2 && $OptModType == 1){ eval ('$NewSum = $sum' . $ModType . '$ModValue ;'); return $NewSum; } To summarize, the user inputs the data in the calculator, hit submit and a function is called on that page, which you can see above, passing the data to the function parameters as you see above. The '$Opt' variables are only used (but do have default values) if the user wishes to further modify their calculation. When I echo $NewSum, I receive 0 which means to me Eval return NULL which doesn't make sense. When I test eval() by itself with constant values on a test page, it works but once I include it in a function or if() it fails, what am I doing wrong? I've checked the manual and I don't see anything wrong with my code.

Disregard my last question. I realize it's dangerous, I'll just have to sanitize the data thoroughly. Thanks for the help.

One of my favorites is PHP for Absolute Beginners. I know you said you weren't doing the code anymore, but I have to add something: <input type = “text” name = “userName”> I'm going to guess, that since you're not using $_GET or $_POST (which you should be to pass the data), another issue could be the use of those special quotes are messing things up a bit too. Just use regular double quotes. I could be wrong about that though.

Thanks MasterACE14 and scootash for your replies, it's appreciated. While it may be the 'simpliest' method, is it the 'safest'? That's what I'm considered about regarding using it. The data is stored and dynamically built into selection boxes but still, those values can be changed using certain browser components now-a-days to include just about anything. or am I just being unnecessarily paranoid?

As SergeiSS mentioned, change your code to what he typed and if you'd like to display the names in a list format use what I type below just after the while loop closing bracket. foreach($players as $key => $pList){ echo $pList.'<br>'; } Yes, but you need to have them stored in the database then when doing the query use the ORDER BY command. So for instance, let's say your list of names is stored a database named " "Team_DB" in the following tables: 1. Player_name 3. Team_Name then in your query you'd do something like this: $query = "SELECT `Player_name`, `Team_Name` FROM `Team_DB` ORDER BY `Team_Name`"; The above will list them by team, or you can simply remove the ORDER BY command and use PHP to display the output based on team if you're going for aesthetics.

Hey all, I'm building a pretty extensive calculator program for my users but I'm stuck on the best way to doe the math operation. I currently have all data stored in a database (such as the integers and the operation symbols +, -, *, / , % etc) because the calculator page is completely dynamic. The symbols are queried from the DB via id number. Right now I'm using a switch statement to handle everything but that switch statement is huge, it's almost 24 cases long and I want to compact this into an array for functionality purposes and speed. I've tried everything from eval() (which I do not want to use unless I absolutely have no other choice), concatenating the variables together and while this shows what equation is supposed to take place, it doesn't perform the actual equation because the operator symbol is just a string. I'm truly stuck and have been researching a solution almost two days. here's a clip of the switch and case depends upon which operation the user wishes to perform: switch($Calc){ case 2: $Total = $firstvalue + $secondvalue; break; case 3: $Total = $firstvalue - $secondvalue; break; case 4: $Total = $firstvalue * $secondvalue; break; case 5: $Total = $firstvalue / $secondvalue; break; case 6: $Total = $firstvalue % $secondvalue; break; default: echo 'No modifier selected!'; break; } I said earlier, this is just a snippet of the switch, the original is 24 cases long and I really don't want to have to use a switch if I can get away with it but I'm not sure how to do this so I can use an array or a nested array loop. Thank you for your help.

Hey laffin, Actually the problem was me not being able to insert the elements and the above code is a snippet from a program that requires that information, but like it does most of the time, my brain malfunctioned and I was having the dickens of a time trying to resolve the issue. I think I suffer from early alzheimers at times

Hi AyKay and Thorpe, When I saw what you two posted, I literally did this => *groan and face palm* I'm now hanging my head in shame lol. I completely spaced placing the array outside of the loop. Thank you both for your help, and the concise explanation. They both were definitely appreciated!

Hello all, What I'm trying to do is insert dynamic data supplied by the user into an array, but for some reason, the loop only builds arrays inside of arrays (or so it seems) and doesn't create an array with unique indexes and associated data. I was hoping someone could point me in the right path? I've searched numerous forums, threads and google but cannot find an answer. Here is the code snippet I'm working on. What it's supposed to do is collect a user's input, which is a Quantity amount and a high number, and based on that amount, create an array of random integers. This is my latest attempt. Now, maybe I'm just losing it, but when I place print_r($output) inside the loop, I see how it's being created but no unique indexes, just nested arrays. When I place it outside of the loop, I only receive one array with one index and value even though a high quantity was sent to the script. $i = 1; while ($i <= $Quantity){ $output = array(rand($RandLow, $RandHigh)); $i++; } print_r($output); Here is another attempt, which again proved to be unsuccessful, at least to my tire brain. $i = 1; while ($i <= $Quantity){ $output = rand($RandLow, $RandHigh); $total = array($output); $i++; } print_r($total); I've tried the for() loop as well but I just can't seem to make heads or tails of this and I'm sure it's going to be something simple that I'm missing. Thanks in advance for any help and insight if you know a better way to do this.

I didn't even know about GClientGeocoder, thanks for the heads up. Also, when I stated, "They're storing the information locally" I meant the user's information is being stored locally in their (the client's) own internal database. Thanks for the code snippet Little Guy, I'll see what I can do with it. Unfortunately I'm not sure if it's going to be what they want because the site owner wants that information created dynamically when the user inputs it in and as far as I know, they don't want to do that using a predetermined list of coordinates but rather general city, state/province, country stuff.

Ok, I naturally assumed someone would suggest GoogleMaps, but seeing as they want custom markers based on various user status and they want the map to auto-update based on location entered by the user and from what I've seen on GoogleMaps API (unless I'm looking at the wrong API), the locations (coordinates) are predetermined within the script itself and I don't see where the I can customize the markers themselves. So, how do I go about doing this with GoogleMaps API? I'm sure I'm just missing something.

Hey all, Not sure if this is the proper place for my question and if it isn't, I apologize in advance. I've recently began building this website and one of the desired aspects is to allow their users to input their location (city, state / province and country) and have PHP automatically create markers on a map of the location. I'm not sure PHP can even do this, sounds more like a JavaScript / Ajax thing but does anyone know of a script or open source program that can do what I'm describing? or at least can provide me some direction because I have absolutely no idea on where to start looking and before someone suggests GoogleMaps, they're storing the information locally so GoogleMaps won't work in this case as far as I know. Thanks for any help you can provide!
