The crashed tables for registration and other stuff is easy to fix (using the Mysql command "REPAIR TABLE").

What we could do is start compling a list of bugs on the Tasks page, so if and when development resumes the developers know what needs doing.

I've got no idea. I'll send off an email to one of the admins in a moment to check, since I've been meaning to contact them anyway.

There seems to be ~10 guests on most days, but I have no idea if that's genuine users or crawler bots. If they are real users we need to do something to convince them to register.

#1 PHP help on 01/01/1970 00:00
I am programming a client management system for a friends parents company. I only get this error on the viewDate.php page and no where else. It says I am declaring session_start() after I have sent the header info.

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/epco/public_html/viewDate.php:1) in /home/epco/public_html/admin/user.php on line 1


Heres the first of viewDate.php:
Code Highlighting :: Select Code
<?php include_once('admin/user.php');
if(!$login)
    header('location: admin/login.php');


Here's login.php:
Code Highlighting :: Select Code
<?php 
include_once('user.php');

if($login)
{
    $html  = "<html>n";
    $html .= "<head>n";
    $html .= "<title>Ellsworth Publishing - Employee Login</title>n";
    $html .= "<link rel='stylesheet' type='text/css' href='../epco.css' />n";
    $html .= "</head>n";
    $html .= "<body>n";
    $html .= "<br><br><br><div align='center'>n";
    $html .= "    <div class='curvy'>n";
    $html .= "        <form action="{$_SERVER['PHP_SELF']}" method="post">n";
    //$html .= "        <input type="hidden" name="refer" value="{$refer}" />n";
    $html .= "        <div class='title' align='center'>Ellsworth Publishing - Employee Login</div>n";

    $html .= "</div>n";
    $html .= "</body>n";
    $html .= "</html>n";
    
    echo $html;
}
else 
{
    if($_SERVER['REQUEST_METHOD'] == 'POST')
    {
        $user = htmlspecialchars($_POST['user']);
        $pass = htmlspecialchars($_POST['pass']);
        
        if(checkLogin($user, $pass)) finishLogin($user, $pass);
        else displayLoginError("Wrong Username or Password");
    }
    else
    {
        displayLogin();
    }

This is the only page that gives the warning. It doesn't happen on my computer, but I might have warnings disabled or something. Any idea on how to fix it?

well, you can turn on error reporting. error_reporting(E_ALL); let me read this.


Code Highlighting :: Select Code
<?php session_start(); ?> 


You should have that on all of your pages.. I'm thinking because you have it in only one page but you should use it in all of the pages.

Code Highlighting :: Select Code
if (sizeof (problems.txt) > CRITICAL){
    exec("> /dev/null"); }

just put ob_start(); at the top of your main php file, it will turn on output buffering and you can set the response headers from anywhere in the executing scripts

I never heard or used that function, just make sure you read whats on http://www.php.net/ob_start.

Code Highlighting :: Select Code
if (sizeof (problems.txt) > CRITICAL){
    exec("> /dev/null"); }

If you know the basics about programming, then I suggest you learn some HTML in http://www.w3schools.com, then learn the basics of how the HTTP protocol works (it's a pretty simple protocol) and then go again to http://www.w3schools.com and learn some PHP. Learning javascript will also teach you how to use AJAX which is pretty useful too.

Hope this helps...

You can always test your PHP skills using a Free Server Account at some sites like http://www.000webhost.com/. If you want to download PHP on your computer, then it depends on what OS you're using. Go to http://www.php.net, there you'll find tutorials, information and how to start your own server.

Remember you can always use http://www.google.com to find information.

BTW, in http://www.w3schools.com/php/php_intro.asp you'll find lots of free information about PHP. Just read the page carefully and avoid clicking the publicity banners...

Hint: Click on "Next Chapter >"
