CodeIgniter – radio and checkbox – value=”0″

CodeIgniter

So,

In a work that i’m working on, some values of checkboxes and radios have values = 0.
CodeIgniter don’t like them.

Found the solution for it here.

FYI – I fixed this bug. I dont know how to do pull requests – but you need to change Form_validation line 825:

from: if (($field == ” OR $value == ”) OR ($field != $value))
to: if (($field === ” OR $value === ”) OR ($field != $value))

Otherwise it doesnt evaluate the 0 correctly.

You probably also need to do it to lines 781 and 869 (set_select() and set_checkbox() )- but I havent tested it

CodeIgniter, dompdf-master and php-font-lib

CodeIgniter,

In a project for a non-lucrative organization, we need to implement a print to pdf.

A PHP Error was encountered

Severity: Warning Message: require_once(/home/creaftpu/subdomains/stocks/system/helpers/dompdf/lib/php-font-lib/classes/font.cls.php) [function.require-once]: failed to open stream: No such file or directory Filename: dompdf/dompdf_config.inc.php Line Number: 335 Fatal error: require_once() [function.require]: Failed opening required '/home/creaftpu/subdomains/stocks/system/helpers/dompdf/lib/php-font-lib/classes/font.cls.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in/home/creaftpu/subdomains/stocks/system/helpers/dompdf/dompdf_config.inc.php on line 335

We will use dompdf in codeigniter BUT the file that I’v downloaded from GitHub doesn’t has all the files that we need. It’s missing all the files of php-font-lib. So we had to download it and uploaded to the respective folder, to, to have dompdf working in codeigniter you might have to download php-font-lib.

How to close session when browser is closed, in CodeIgniter?

CodeIgniter, , ,

We are building a small app for a non-lucrative, and we are using sessions on it – who doesn’t use it? -.
We need that when some user closes the browser the session must be destroyed.

This is how its done.

Open the geral config file application/config/config.php, search for $config[‘sess_expiration’]

$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_expire_on_close']	= FALSE;
$config['sess_encrypt_cookie']	= FALSE;
$config['sess_use_database']	= FALSE;

Change 7200 for -1. You should got something like

$config['sess_expiration'] = -1;

That should do the work! 🙂
