User class help...

[sean04]

Can someone give me a hand on getting this working maybe how to use it and what not.. I'm trying but not very successful lol. I want to call the loaduser on the profile page..

 

<?php
include "Database.php";
class User{

//Constructor - Create a new user
function User(){
}

//Constructor - Load an existing user
function LoaddUser($userID){
	$this->LoadUser($UserID);
}

function LoadUser($userID){
	//$db = new Database();
	$results = mysql_fetch_array(mysql_query("SELECT * FROM userInfo WHERE User_ID = '$userID'"));

	$UserID = $results[userID];
	$Email_Address = $results[Email_Address];
	$Password = $results[Password];
	$Name = $results[Name];
	$Screen_Name = $results[screen_Name];

	return $results;
}
}

?>

 

Thanks,

Sean

I hope Database.php contains a Database class?

 

If so, you write:

 

class UserGateway {
     private $db = null;
     function __construct(Database $db) {
         $this->db = $db;
     }
     
     function getAllUsers() {
         return new UserList($this->db->fetchAll('SELECT * FROM users'));
     }
     
     function findUserById($id) {
         return new User($this->db->fetchRow('SELECT * FROM users WHERE id = ..'));
     }
     
     function findUsersByLastName($lastName) {
         return new UserList(..);
     }
}

Yes it does contain a Database class

 

Thanks for the reply!

 

So I wouldn't do anything like I posted right? Like loading all the users information? or should I just do that on the profile.php

 

Thanks again,

Sean

On the profile page you would call:

 

$user = $gateway->findUserById(1);

[sean04]

Thanks! I will give this a try!

 

Do you recommend anything like this as a function?

 

function LoadUser($userID){

//$db = new Database();

$results = mysql_fetch_array(mysql_query("SELECT * FROM userInfo WHERE User_ID = '$userID'"));

$UserID = $results[userID];

$Email_Address = $results[Email_Address];

$Password = $results[Password];

$Name = $results[Name];

$Screen_Name = $results[screen_Name];

return $results;

}

 

or should i just implement that right in the profile page?

 

Thanks,

Sean

1) I see that stuff from $results go into variables like $Name in the function LoadUser. What happens to these variables after the function returns $results?

 

2) What happens to the array that LoadUser returns?

 

3) Go and google about PHP Arrays and how String indexes work in Arrays.

Actually what I've done doesn't really make any sense i guess lol.

 

Thanks,

Well, back to the drawing board with new lessons learned, and some questions on your mind to guide you, then. We all have to do that.

Thanks!

 

Another question... how would I get this to output on the profile page? Here is the function:

function GetFriends($User_ID){
		if($User_ID != null){
			$getUserFriends = mysql_query("SELECT * FROM `userfriends` WHERE `User_ID` = '$User_ID'") or die(mysql_error());
			$totalUserFriends = mysql_num_rows($getUserFriends);
			while ($UserFriends = mysql_fetch_array($getUserFriends)) {
				$getRequesterInfo = mysql_fetch_array(mysql_query("SELECT * FROM `viewInformation` WHERE `User_ID` = '$UserFriends[Friends_User_ID]'")) or die(mysql_error()); //gets requests
				if($getRequesterInfo[Picture_Link] != "") {
					echo"<a href='user_profile.php?User=$RequesterInfo[user_ID]'><img src='$RequesterInfo[Picture_Link]' border='2' height='75' width='75'></a><p/>"; }else{echo"<a href='user_profile.php?User=$RequesterInfo[user_ID]'><img src='".$defaultProfilePicture."' border='2' height='75' width='75'></a><p/>";
				}
				echo "<a href='user_profile.php?User=$RequesterInfo[user_ID]'>$RequesterInfo[screen_Name]</a> - ";
				echo "<a href='?verifydelete&quickViewUser=$RequesterInfo[user_ID]'>Remove</a><br><p/></div>";
	}
	return(GetFriends);

}

 

That function is in a class called User... Here is what I'm using on the profile page to call it:

$user = $User->GetFriends($User_ID);

 

And that doesn't work lol... I know it probably need a lot of cleaning up and i know I'm not returning the correct value lol.

 

Thanks for any help,

Sean

Ok I got it working finally. I just need to know if this is the proper way to do it? If there is something that would work better please let me know.

 

function GetFriends($User_ID){

	if($User_ID != null){

	$getUserFriends = mysql_query("SELECT * FROM user_friends WHERE $_SESSION[userID] = '$User_ID'") or die(mysql_error());
	$totalUserFriends = mysql_num_rows($getUserFriends);

	while ($UserFriends = mysql_fetch_array($getUserFriends)) {
		echo"<div class=ViewList>";
		$getFriendInformation = mysql_fetch_array(mysql_query("SELECT * FROM `viewInformation` WHERE `User_ID` = '$UserFriends[Friends_User_ID]'"));
		if($getFriendInformation[Picture_Link] != "") {
			echo"<a href='user_profile.php?User=$getFriendInformation[user_ID]'><img src='$getFriendInformation[Picture_Link]' border='2' height='75' width='75'></a><p/>"; }else{echo"<a href='user_profile.php?User=$getFriendInformation[user_ID]'><img src='".$defaultProfilePicture."' border='2' height='75' width='75'></a><p/>";
		}
		echo "<a href='user_profile.php?User=$getFriendInformation[user_ID]'>$getFriendInformation[screen_Name]</a> - ";
		echo "<a href='?verifydelete&quickViewUser=$getFriendInformation[user_ID]'>Remove</a><br><p/></div>";
	}
	return $UserFriends;
}

 

This is what I use to call the function:

 

User::GetFriends(1);

 

 

Suggestions?

 

Thanks,

Sean

I'm not entirely sure what you want your code to do. Could you describe, in one or two sentences, what you want to print?

[ignace]

If you want to call it like:

 

User::GetFriends(1);

 

Then you should add static to your function declaration:

 

static function GetFriends(..

 

But IMO it doesn't make any sense because User is a representation of the actual user on your system and it would make more sense to write something like:

 

$User->GetFriends();

 

Which would return a FriendList (or UserList)
