[time interval help]

You could always have a field in a database, that basically lets YOU know if the user has collected their gained money within the pass 24 hours. Then use time() and check the difference between the time last collected.

 

So we can do something like this:

 

<?php
$sql = "SELECT * FROM `phpbb_dseusers` WHERE `user_id` = " . $user->date['user_id'];
$res = mysql_query($sql) or die(mysql_error());

while($row = mysql_fetch_assoc($res)){
# do other things we'll do time
$time = time();
$last = $row['last_collected']; # you might have to add this into your database
$day = 3600*24;
$total = $time-$last;
$collection = $row['collected'];

if($collection == '0'){
# give points for first time
# update last_collected field with time();
# update collected with the number 1
}else {

	if($total >= $day){
	# give points
	# update last_collected field with time();
	}
}
}
?>

[[SOLVED] syntax error message]

Do:

 

$title = mysql_real_escape_string($_POST['title']);
$cust = mysql_real_escape_string($_POST['cust_id']);

$query = "INSERT INTO `upload2` (`name`,`size`,`typr`,`path`,`title`,`cust_id`)
             VALUES('$fileName','$fileSize','$fileType','$filePath','$title','$cust');";

mysql_query($query) or die("Error, query failed: " . mysql_error());

 

You had an extra comma after cust_id

[[SOLVED] Using a Function in preg_replace]

Worked like a charm, tyvm.

[[SOLVED] Using a Function in preg_replace]

Should that matter?

 

$post = "[user=matt]";

 

 

[[SOLVED] Using a Function in preg_replace]

I have:

 

$post = preg_replace ("/\[user=(.*?)\]/is",uname2("$1"),$post);

 

and the function

 

function uname2($value){
$sql = "SELECT * FROM `users` WHERE `username`='$value'";
$res = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_assoc($res);

return "<a href=\"/profiles.php?user={$row['username']}\" style=\"text-decoration:none;\"><img src=\"/images/users/ui_{$row['level']}.png\" alt=\"\" border=\"0\"> {$row['username']}</a>\n";
}

 

My result: �

 

Basically I suppose the actually value inside the uname2 function isn't necessarily being passed.

[login page]

Heh.

 

You could easily simplify that to a much smaller page, and easier to work with.

 

/*
create a page form.php which can hold just the form itselfs
  use an array based error system
*/

if(!$_POST['submit']){
include "./form.php";
}else {
# your variables
$username = mysql_real_escape_string($_POST['username']);
$password = mysql_real_escape_string($_POST['password']);
//etc...

$errors = array();

   if(!$username){ $errors[] = "You did not supply a username"; }
   if(!$password){ $errors[] = "You did not supply a password"; }
   #etc

   if(count($errors) > 0){
      foreach($errors AS $error){
      echo $error . "<br>\n";
      }
   include "./form.php";
   }else {
   # register
   }
}

$_SERVER['HTTP_REFERRER'];

 

The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted.

Ah, you're calling it inside a function.

 

after you open the function add this:

 

global $errors;

[[SOLVED] Foreach error]

Do something like:

 

$errors = array();

//for each error you have name it $errors[]

$errors[] = "first error";
$errors[] = "second error";
$errors[] = "third error";

foreach($errors AS $error){
echo $error . "<br>\n";
}

[not a valid MySQL-Link resource]

By appropriateness of a function, the variable $con is obviously defined OUTSIDE the function. So you need to globalize the variable.

 

$con = "connection to db";

function whatever($this){
global $con;
// other stuff
}

[SQL unexpected error]

You could just put curly braces around the variables.

You can just store every value in either session, or cookies.

It's not usually the best to use session and cookies at the same time. Also, the only real way to end a cookie is to set the expiration time back from where it started.
