================== Installation

Unpack Polr, or clone the git repo. Only the git clone option allows quick updating through git pull.
Go to the root of your Polr folder (on webserver)
Read INSTALL.txt
MySQL warning: Set your character set to UTF8. Some character sets are vulnerable to a certain bug in MySQL and mysqli_real_escape_string. For more information, please see http://stackoverflow.com/questions/5741187/sql-injection-that-gets-around-mysql-real-escape-string. This bug should be mostly fixed >1.1.0.
You're ready to go! Check back for updates, and git pull if possible to update Polr. Otherwise, you can download a ZIP from Github and replace your current files. Make sure to keep your config.php!

Prerequisites:

mod_rewrite (install help: https://www.digitalocean.com/community/tutorials/how-to-set-up-mod_rewrite)
MySQL or MariaDB equivalent >= 5.5
PHP >= 5.4
Apache httpd
MySQLi extension for PHP
MySQLnd (native driver; i.e php5-mysqlnd on Ubuntu)
MCrypt (http://www.php.net//manual/en/book.mcrypt.php)

The list may be long, but most hosts include these prerequisites in PHP stacks, so you don't have to install them yourself.

================== Troubleshooting

###I get a blank page at the user dashboard (/admin/)

This error occurs when your PHP installation's version is older than 5.3, or because you do not have either the PHP mysqli extension or do not have the MySQLnd (native driver). On Ubuntu, you simply need to sudo apt-get install php5-mysqlnd and restart apache2 service apache2 restart. You should have the mysqli.so extension enabled. Ask on IRC if you need further support.

###I get a blank page when trying to register (registerproc.php)

This may mean you do not have the MCrypt extension for PHP. To install this on Ubuntu, run the following commands:

sudo apt-get install php5-mcrypt
sudo mv -i /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/
sudo php5enmod mcrypt
sudo service apache2 restart

On Fedora/Centos:

yum update
yum install php-mcrypt*
sudo php5enmod mcrypt
sudo service apache2 restart

###I have errors enabled, and I get "Illegal String Offset"

This usually occurs when you are missing an extension, and thus, the expected associative arrays (e.g mysqli_fetch_assoc) are instead strings, and errors occur. The most common cause of this is the missing MySQLi extension or native driver. Refer to the first FAQ, or the mysqli_fetch_all FAQ. This issue is usually caused by an old PHP version.

###The links produced give me 404

You need mod_rewrite in order to use Polr. Please take a look at https://www.digitalocean.com/community/tutorials/how-to-set-up-mod_rewrite

###I can't run setup, I get various MySQL errors.

Make sure your host is correct. Some webhosts require you to bind to a certain ip or port, such as 0.0.0.0. You may need to modify the code if you need to use an unconventional port. (option coming soon)

Make sure the database is premade, and that the user has the required permissions to create tables.

###I'm getting an error in the dashboard; Missing mysqli_fetch_all.

This problem occurs if your PHP version is below 5.3 or you do not have the native driver (http://php.net/manual/en/book.mysqlnd.php). If you cannot install the native driver, place this in your req.php file:

function mysqli_fetch_all($res) {
    $array = array();
    while ($row = $res->fetch_assoc()) {
        array_push($array, $row);
    }
    return $array;
}

###I can't install Polr through the setup script.

You probably didn't configure MySQL correctly. Delete config.php and try again.
