functional posted:I'm worried about your code, though. Lines like these: I have security, I just cut it out because it wasn't really part of the logic. You cannot go upwards using .., and the file has to exist before anything is done with it, and the strings are escaped. I don't think you can inject anything. Leaching was not the major concern, just more of a sidenote. Okay, since that is good, what is the easiest way to go about displaying the statistics? Everything I see is either too simple to use, or too complex. Something like http://wettone.com/code/slimstat, except prettier. I doubt I'll find the right package though, I'll probably end up writing my own.

What's the scope of a session_start( ) call? I have a multi-layered AJAX application that filters requests, then forwards each request onto a controller object which then in turn completes the request. At any given time you could propagate over a number of objects, a lot of which rely on session variables and I'm wondering if it's necessary for me to call session_start( ) any time that there is a reference to $_SESSION or will it work if I just call it at the beginning of a request routine?

$_SESSION is a global variable which is initialized by session_start(), so you only need to call the function once per request.

Does the DateTime object actually work in the latest PHP release? I tried instantiating a new DateTime object and doing DateTime.sub to subtract some time, but I get a function not defined error. Am I missing an include or something, or does 'experimental' just mean 'doesn't work at all'? The code is essentially this: <?php $date = new DateTime(formatstring); $date.sub(T1D); ?>

That sounds pretty confusing after reading it, so here's an example: You're trying to get the element's key, not its value. The confusing part is that you're mixing an indexed array with an associative array, since you didn't give the first element a key. php:<?
$header = array("Home","Info"=>array("E-Mail","Other"));
$keys = array_keys($header);
echo $keys[0]; // Prints "0" because this element doesn't have a key
echo $keys[1]; // Prints "Info"

You can iterate over $_GET just like any other array or use isset() to see if anything you're looking for was set. For example, &ascsv might act as a flag to output some report as CSV as long as it's set by checking for isset($_GET['ascsv']). Of course, this could confuse the poo poo out of someone who edits the query string with &ascsv=0 and expects it to work, so take that into consideration  Internet Headache posted:According to SEO guys, search engines hate query strings.

The api is pretty self explanatory. eaccelerator_put($key, $data, $duration) puts $data into the cache with an access key of $key, for $duration seconds. eaccelerator_get($key) tries to retrieve data stored at $key eaccelerator_rm($key) removes entry stored at $key If you just need to know about caching 'theory' in general, just do a search for that.

When using the php DomDocument, what does the error "ID loginForm already defined in entity" mean? I've tried googling for this and I can't find anything that defines the error. I've checked through the HTML and I don't see any duplicate loginForm elements. The only thing I notice is that there is a form id and a form name that is both loginForm. Could that cause this error?

Hi guys, I'm pretty new with queries in PHP and I have a question. I'm setting up a little game for some friends that calculates a budget (each player playing as a nation of their choice). My units table has different types of units such as "army", "navy", etc. You can see the page here: http://www.rickpierce.info/dotw/nations.php I got army subtracting fine with the help of a friend using a LEFT JOIN command. But now I come to adding a second (navy) and I'm lost. My friend suggested subqueries but he's unfamiliar with the process, and I'm feeling in over my head on this one as a beginner. Here's the query and some other information to help you get an idea of what I've done/am trying to do: php:<?
$result = mysql_query("SELECT `nations`.*,SUM(Size) AS `armycount` FROM `nations` LEFT JOIN `units`
ON `units`.`Owner` = `nations`.`NatID` WHERE TYPE='army' GROUP BY `nations`.`NatID`");
...
while($row = mysql_fetch_assoc($result))
{
$percent = $row["Growth"] * 100;
$armycost = $row['armycount'] * 3;
$navycost = $row['navycount'] * 20;
$net = ($row["GDP"] * $row["Growth"]) + $row["GDP"] + $row["Reserve"] - $armycost - $navycost;
?>Edit: broke query in half to stop tables from breaking.

ExtraNoise posted:The hang up is the WHERE TYPE, as I can't just insert another WHERE TYPE='navy' in the query without it falling apart. Running a second query is both stupid and doesn't work. I've tried rearranging the query to incorporate another SUM and WHERE, but because the WHERE needs to be in that exact location in the query, it doesn't work. Unless I'm misunderstanding, you want to use WHERE `type` = 'army' OR `type` = 'navy' Or you could use WHERE `type` IN ('army','navy')

jasonbar posted:Unless I'm misunderstanding, you want to use WHERE `type` = 'army' OR `type` = 'navy' Would it be able to differentiate between the two, or would it SUM up both types? Either way, I'll give it a try! Edit: I should note that I would like it to also create the variable navycount (see armycount) that is the SUM for type="navy", sort of how the query creates a SUM for armycount that is the SUM for type="army". Would I be a lot better off just using separate tables for each type of unit?

I hate to sound rude, but you might need to do a little reading about database normalization before you go much further. The issue of putting 'army' and 'navy' in different tables will become clear, you'll prevent lots of headaches, and the project will turn out better.

I could use some help. Our website guy (goon JH Pufnstuf) departed us ages ago and now my boss wants a few changes done to the website. Between my coworker and myself, we've managed to tackle all but one of the requested fixes, but this one is throwing us both for a loop. Goal: I want to add an onClick variable to a radio button selection. Summary: To access a group of text listings on our site, it's necessary to click on a radio button to indicate the region, and then a drop down menu for a section, before hitting submit and having the values returned. The boss wants it so that after clicking the radio button, but before selecting from the drop down and hitting submit, a temporary page with banner ads (that correspond to region selected by the radio button) pops up in the opposing frame. What we have now: php:<? <form id="form1" name="city" method="get" action="adsbycity_results.php"> <?php $result = mysql_query("SELECT * FROM cities"); while($cities = mysql_fetch_object($result)) { ?> <ul style="list-style: none; margin: 0 0 -7px 0;"><li style="padding: 0 0 0 16px; background: none;"><input type="radio" name="city_id" value="<?php echo $cities->city_id?>" /> <?php echo stripslashes($cities->name)?></li></ul> <?php } ?>?> php:<? <!-- Banner Ads start here --> <?php $city_id = $_GET['city_id']; ?> <?php $category = $_GET['category']; ?> <?php $ban_result = mysql_query("SELECT * FROM banners WHERE city_id='$city_id' AND category='$category'"); while($banners = mysql_fetch_object($ban_result)) { ?> <ul> <li><a href="<?php echo $banners->link?>" target="_blank"><img src="<?php echo $banners->file?>" alt="<?php echo $banners->company?>"></a></li> </ul> <?php } ?>?> php:<? <input type="radio" name="city_id" value="<?php echo $cities->city_id?>" onClick="XXX" />?>

It might be a PHP limitation in which you can only assign static default values to function inputs. For instance, This is probably illegal: php:<?php public function __construct($un = $_POST["username"], $pw = $_POST["password"]) { // ... } ?> php:<?php public function __construct($un = "defaultuser", $pw = "defaultpassword") { // ... } ?>

I'm trying to fix some code that needs to be able to send mail from a website. Right now the line of code for mailing is just: mail($_POST['chrEmail'].", ".$_POST['chrPerson'],$subject,$body,$headers); It needs to include SMPT authentication because I'm moving the code to another server (and their mail server requires login credentials), but since I'm not really that fluent in PHP, I'm having some trouble getting it to work. I know the server name, user name, password, and all that, but I'm not sure how to put it together and the scripts that I've found online look a lot different than just the normal "mail" function. Any ideas?

I'm not too sure how to do this automatically but I'm sure there is a way and I think php is the way to go. I want to update a mysql database according to payments made through paypal. So if someone pays for an upgrade using paypal it automatically upgrades their account by updating the mysql database. The only ways I've thought of was to manually download the paypal transaction list, and get the people to submit a form with their username and paypal transaction number then run a program to compare the lists and update the database. There still seem to be manual steps which I want to remove or reduce somehow. I don't know php , but I figured it wouldn't be that hard to learn. Edit: It was quite easy once I found the sandbox page for paypal and looked at the documentation and stuff there. FSMC fucked around with this message at 00:11 on Jan 18, 2009 |
