| | Hey, "boolean" is not a data type, look at the correct definition/declartion Also, are you defining the function prototypes before main (since you're using them after main) because if not, the program won't know where to call the fucntions. Hope this helps :)  |
 | Hey, I might be having a blonde moment but here goes.. I'm trying to split a massive 1D vector into blocks at different places (If that makes sense), it should basically go like this: 0 201 401 601 801 .. .. .., 57201 2 202 402 602 .. .. .. …  |
| | Hey, Numbers_roman::tonumeral($year); *This looks like a namespace, however, I might be wrong. See: http://php.net/manual/en/language.namespaces.php* and require_once("numbers/roman.php") This this includes the file, but, instead of the "include" function which will only execute an error, this function will die if there is an error. By using the require_once, it will check to … |

| | @griseindria - Just select it off SESSIONS then..? I.e. <?php if(!isset($_SESSION['user_session'])) exit("You do not have permission to access this page, sorry"); $query = "SELECT * FROM profile WHERE user_id='{$_SESSION['user_id']}'"; $res = mysql_query($query); if(!mysql_affected_rows() == 1) exit("Couldn't find the details"); while($row = mysql_fetch_array($res)) { // only display the users details } … |
| | Shouldn't this: <?php while($row = mysql_fetch_array($result)) { echo "<a href='members_profile.php?id=<?php echo $row[0];?>' >" .$row['username'] . ', '; } ?> Be this: <?php while($row = mysql_fetch_array($result)) { echo '<a href="members_profile.php?id=' .$row[0]. '">' .$row['username']. '</a>'; } ?> Also, with this code: <?php session_start(); Connected to database here $sql = "select * from … |
 | Hey, why not try mysql_affected_rows()? E.g. //This session value is created at login $username = $_SESSION['valid']; //This is written to the URL $server_id = $_GET['server']; //See if a server exists with this ID and Username $query_server = "SELECT id FROM servers WHERE id='".$server_id."' AND `administrator`='".$username."'"; $result=mysql_query($query_server); if(mysql_affected_rows() == 1) { … |

| | Re: arrays Hey, You need to firstly look into arrays, and, then how to pass (array pointers) into functions, once you've found these things out you can then sort the array (bubble sort e.g.) and find the lowest value. Not allowed to provide a solution to this probem!  |

 | Re: Case Statements Hey, You're not breaking your cases, after each case you need to have a break otherwise it may just jump to the next case etc. Also, you need to have/suggested that you always have a default case. Here's an example: int main() { int number; switch(number) { case 0: // … |

| | Just a quick question.. (I'm very tired so might be missing the point)! But if I had this code: <?php global $json_news; var_dump($json_news); echo"<br/>=======================<hr/>"; ?> It would return NULL because although you are defining $json_news as a global, you're not setting it as anything.. Surely, your function whats to return … |

| | Hello, I'm not an expert in this field, but, I'm sure you can stream the security camera to a web-server. I don't really /think/ this can be done in PHP and therefore PHP only handles which camera is shown, for example switch between HOUSE 1 and HOUSE 2 and also …  |

| | On the first line of XICS.php you have this line: <?php $mysqli = new mysqli(HOST, USER, PASSWORD, DATABASE); sec_session_start(); ?> Well, you're defining the constant "HOST", "USER", "PASSWORD", "DATABASE" in the file, process_login.php - So it looks, from looking at the code it doesn't know where it is.. So in … |
 | Hello, Vectors are arrays, but, arrays are defined in size (memory allocations) whereas Vectors are dynamically assigned, in memory. So for example, if you reach the maximum capacity in an array it will run out of memory whereas vectors will just change it's size dynamically and therefore allocate more memory. … |
