Hi,

Ive spent about 3 hours now troubleshooting this tutorial and every time I get a blank page on my local server with absolutely nothing on it.

an someone please help?

Here is my code for ini.inc.php

<?php

session_start();

mysql_connect('localhost','root','mypass');
mysql_select_db('user_profile');


$path = dirname(__file__);

include("{$path}/inc/user.inc.php");



$_SESSION['uid'] = 1;

?>

and for profile.php

<?php

include('core/init.inc.php');

$user_info = fetch_user_info($_GET['uid']);

?>

Could you post your user.inc.php file? The problem might be in the fetch_user_info function.

Posted: **Wed Feb 08, 2012 12:38 am**

<?php

function fetch_users(){

	$result = mysql_query('SELECT `user_id` AS `id`, `user_username` AS `username` FROM `users`');

    $users = array();
    
    while (($row = mysql_fetch_assoc($result)) !== false){
        $users[] = $row;
    }

	return $users;
}





?>

Thanks for the reply....I'm really stumped

well.. there's your problem... you don't have the fetch_user_info function. You need to create that first.

It should have shown an error. Put

error_reporting(E_ALL);

at the top of your init.inc.php to see if it gives you an error.

Thanks again for replying and the assistance but it still did nothing. When I run profile.php I get a completely white/blank page with nothing on it at all.

I added this code

function fetch_user_info($uid){
	$uid = (int)$uid;


	$sql = "SELECT
				`user_username` AS `username`,
				`user_firstname` AS `firstname`,
				`user_lastname` AS `lastname`,
				`user_email` AS `email`,
				`user_about` AS `about`,
				`user_location` AS `location`,
				`user_gender` AS `gender`'
			FROM `users`
			WHERE `user_id` = {$uid}";
			
	$result = mysql_query($sql);			
	
	return mysql_fetch_assoc($result);			
}

But still I get a blank page.

Here is my error

error_reporting(E_ALL); Warning: session_start(): Cannot send session cookie - headers already sent by (output started at -:4) in - on line 7 Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at -:4) in - on line 7 Warning: mysql_connect(): [2002] No such file or directory (trying to connect via unix:///var/mysql/mysql.sock) in - on line 9 Warning: mysql_connect(): No such file or directory in - on line 9 Warning: mysql_select_db(): [2002] No such file or directory (trying to connect via unix:///var/mysql/mysql.sock) in - on line 10 Warning: mysql_select_db(): No such file or directory in - on line 10 Warning: mysql_select_db(): A link to the server could not be established in - on line 10 Warning: include(./inc/user.inc.php): failed to open stream: No such file or directory in - on line 15 Warning: include(): Failed opening './inc/user.inc.php' for inclusion (include_path='.:') in - on line 15

IS the source for this tutorial posted someplace???????

Ive gone over this thing 8 times and can't understand why this wont work.

The errors lead me to believe that you have something before the opening <?php tag in your init file and that you're not connecting properly to a MySQL server. Are you sure the MySQL server is running? I started getting similar errors when I turned off MySQL in XAMPP.

Posted: **Thu Feb 09, 2012 5:32 pm**

thanks again for the help.

I just checked and there is nothing before the opening php tag and the mysql, localhost, tec are working fine too.

is it possible this code is not letting me connect?

#
$path = dirname(__file__);
#
 
#
include("{$path}/inc/user.inc.php");

Is there another way to access the inc/user.inc.php file instead of this?

thanks

That code is working perfectly. Nothing wrong there.

I can't see what would cause your code to fail like this.

Could you post all of your code again?

thanks again for taking the time to help me with this.

Here is my code: ini.inc.php

<?php


session_start();

mysql_connect('localhost','root','mypass');
mysql_select_db('user_profile');


$path = dirname(__file__);

include("{$path}/inc/user.inc.php");



$_SESSION['uid'] = 1;

?>

user.inc.php

<?php

function fetch_users(){

	$result = mysql_query('SELECT `user_id` AS `id`, `user_username` AS `username` FROM `users`');

    $users = array();
    
    while (($row = mysql_fetch_assoc($result)) !== false){
        $users[] = $row;
    }

	return $users;
}


function fetch_user_info($uid){
	$uid = (int)$uid;


	$sql = "SELECT
				`user_username` AS `username`,
				`user_firstname` AS `firstname`,
				`user_lastname` AS `lastname`,
				`user_email` AS `email`,
				`user_about` AS `about`,
				`user_location` AS `location`,
				`user_gender` AS `gender`'
			FROM `users`
			WHERE `user_id` = {$uid}";
			
	$result = mysql_query($sql);			
	
	return mysql_fetch_assoc($result);			
}
?>

profile.php

<?php

include('core/init.inc.php');

$user_info = fetch_user_info($_GET['uid']);


?>

Ok just figured something out......I did not create the inc folder and that seemed to fix the connect problem, obviously.

Now I am getting a message that says "that user does not exist". So I think my user_info is certainly returning false but I am not sure why as I populated my database. Is there something I should look for to troubleshoot this. I am very, very new to PHP and don't know what code to check errors in my dataase?

It looks like I'm not connecting or finding 'core/init.inc.php'. but why????? My user_list is also showing the two members I entered so that connects for some reason?

Thanks again
Rob

Oh, okay.

Echo mysql_error(); right under your query but before the return line in fetch_user_info and see if it gives you an error.

Posted: **Fri Feb 10, 2012 8:32 pm**

Ok, I tried that and I got this:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' FROM `users` WHERE `user_id` = 0' at line 8
That user does not exist.

But I don't know what this means or what syntax I should use, nor where I can reference my manuel.

Do you understand this or what's wrong?
thanks
Rob

Yes. It means you need to put semiqoutes ( ' ) around {$uid}. The fact that it said user_id = 0 means that the $uid variable is unreadable. Semiqoutes should change that.

  WHERE `user_id` = '{$uid}'";

Posted: **Sat Feb 11, 2012 8:14 pm**

Ok, I changed that to semi quotes around the var and I still get the same error. I also found an error in the gender line and had a semi quote instead of a comma, I changed that too and still get the same error.

Any ideas????

Really stumped

Ah yes.
Remove that comma

there's not supposed to be anything after that line since it's the "last" line.

Posted: **Sat Feb 11, 2012 9:01 pm**

I removed the comma and still get the same error message. Why is this TUT not working for me?????

Posted: **Sat Feb 11, 2012 11:38 pm**

what does your SQL look like now?

Posted: **Sun Feb 12, 2012 6:53 pm**

like this:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM `users` WHERE `user_id` = '0'' at line 9
That user does not exist.

Posted: **Sun Feb 12, 2012 8:09 pm**

that's your error. I was thinking about the actual SQL code.

Posted: **Mon Feb 13, 2012 8:42 am**

SQLin user_profile is:

SELECT * 
FROM  `users` 
LIMIT 0 , 30

sql in users:

SELECT  `user_id` ,  `user_username` ,  `user_firstname` ,  `user_lastname` ,  `user_email` ,  `user_about` ,  `user_location` ,  `user_gender` 
FROM  `user_profile`.`users` 
LIMIT 0 , 30

Also since removing that comma after gender I'm getting no error, just says that user does not exist and a blank page other than that....

function fetch_user_info($uid){
	$uid = (int)$uid;


	$sql = "SELECT 
				`user_username` AS `username`,
				`user_firstname` AS `firstname`,
				`user_lastname` AS `lastname`,
				`user_email` AS `email`,
				`user_about` AS `about`,
				`user_location` AS `location`,
				`user_gender` AS `gender`
			FROM `users`
			WHERE `user_id` = '{$uid}'";
			
	$result = mysql_query($sql);			
	
	Echo mysql_error();

	
	return mysql_fetch_assoc($result);			
}

Also under indexes at the very bottom of the sql database it says : PRIMARY BTREE Yes No user_id 2 A
