I need to use this Class in a CI 2.1 project, and I would like to know how to convert it to work on CI.
Code: http://pastebin.com/HKTvWsGK
I tried this:
I copied the class php file to the application/libraries/ folder, and then wrote this in a controller:
$this->load->helper('file');
$json = read_file('assets/js/config.json');
$config = 'var configFile = ' . $json;
$this->load->library('JavaScriptPacker');
$myPacker = new JavaScriptPacker($config);
$packed = $myPacker->pack();
echo $packed;
But I get this Warning message when I run it:
A PHP Error was encountered
Severity: Warning
Message: Missing argument 1 for JavaScriptPacker::__construct(), called in /var/www/myapp/system/core/Loader.php on line 1099 and defined
Filename: libraries/JavaScriptPacker.php
Line Number: 86
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: _script
Filename: libraries/JavaScriptPacker.php
Line Number: 87
Then after that error message, the correct output is shown. But don’t know how to avoid the error message.
Any ideas?
Thanks!
]]>Where should I search to find something about it? I would like to do this in CI and jQuery (client side)
Keep warm

I’m hoping someone else can verify this, I’m not sure if there are confounding factors or not because the query I was running it with was pretty complicated (like 30 joins… ewww)
However, In trying to figure out what was causing the issue, I finally stumbled upon one of the SELECT columns was causing it. I did a binary search, and just kept cutting it in half until I found the troubled area.
Turns out the cause was a ‘smalldatetime’ column. I deleted it, and the query worked and the page displayed. Magic, right?
Well to go a step further, since I’m just on a test database, I changed the column type to datetime on SQL Server, and put it back in the query. It worked again, so I changed it back. Broken.
I’m running Ubuntu 10.04 with Apache 2.2.14 PHP 5.3.2-1ubuntu4.13, mssql. I tried with and without eaccelerator (on a second identical ubuntu box [did a fresh install to make sure I wasn’t crazy]). The database is MS SQL Server 2008 R2.
I’m not sure if this is a driver bug, mssql(sybase?) driver bug, or just something else. I’m not sure where to begin with blank pages, because the actual log says the page is being output correctly, the database analyzer says the query completes successfully… It’s just bizarre.
]]>How/where can I put this function so that I can access it from within any controller/model or view etc?
function get_setting($setting)
{
$query = $this->db->where('setting_name',$setting)->get('settings')->row();
return $query->value;
}
I tried putting it in a helper but the db class doesn’t work from helpers I guess?
Thanks!
application/core/MY_Controller.php
<?php

{
parent::__construct();
$this->template_data['page_title'] = 'My Site';
$this->template_data['stylesheets'][] = 'css/styles.css';

$this->load->view( 'page_template_home', $this->template_data );
}
}
When I run it I get a PHP error:
A PHP Error was encountered

info: I’m updating from CI 1.6.3 to 2.1.0 - In 1.6.3 MY_Controller was an extension to Controller and resided in application/libraries - In 2.1.0 MY_Controller is an extension to CI_Controller and resides in application/core - I can’t spot my faux pas… please verify.

I’ve been pondering how to do some routing for a rather large system, and wanted to try and keep it as minimal as possible.
So, I was hoping that you may be able to answer some of my questions.
1) I noticed someone using code like this on the forum in a route, is this right and can anyone explain more? From what I understand it means you don’t have to do each one seperately.
$route['(home/contact/about)'] = 'main/$1';
2) If the system I’m building is built off of a CMS, and the user adds pages etc, most of the page urls are not going to be known, but need to be at the root ‘url’, e.g. example.com/my_new_page
How can I effectively direct that to the correct page, when there’s also going to be things like categories, sub categories, products etc (categories would be at the root, e.g. example.com/fruit)
As from what I can tell, I can’t use a simple :any or reg xp to do it, as I’m not going to know if it’s a page or a category!?
That’s all for now ... Thank you.
Thanks,
Appealing Studio
I have read the user guide thoroughly on Libraries. Given I have never done this before there is a clear learning overhead. I don’t really understand how best to pass parameters from multiple sources into 1 instance of ‘sendmail()’
The other part of me says to heck with it. I will just place ‘sendmail()’ into my controllers 5 times and update the parameters in each ... easy.
What is the best practice ?? Where si the dividing line when good programmers go ‘easy’ or ‘hard’ ?
I guess if there was a great tuorial with examples that would make things easier too - as the user guide is limited.
If there are any resources I shoud look at or ideas - as ever I am Very Gratefull !

Here’s the simple controller and model functions i’m trying to use. The links seems to produce the offset i need to use in my query rather than the actual page number. I’m confused….
<?php
public function booking_list()
{
$page = (int) $this->uri->segment(3);
$count = $this->book_model->count_upcoming($this->session->userdata('username'));
$config['base_url'] = base_url().'listing/booking_list/';
$config['total_rows'] = $count;
$config['per_page'] = 2;
$bookings = $this->book_model->upcoming($this->session->userdata('username'),$page,$config['per_page']);
echo "<pre>";
print_r($bookings);
echo "</pre>";
echo $this->pagination->create_links();
}
?>
book_model functions
<?php
function count_upcoming($username)
{
$today = date("Y-m-d");
$query = $this->db->query("SELECT id FROM Bookings WHERE DATE(last_night) >= '$today' AND username = '$username' AND deleted = '0000-00-00 00:00:00' AND unavailable = '0'");
return $query->num_rows();
}
function upcoming($username,$page = 0,$per_page = 2)
{
$offset = $page * $per_page;
$today = date("Y-m-d");
$query = $this->db->query("SELECT * FROM Bookings WHERE DATE(last_night) >= '$today' AND username = '$username' AND deleted = '0000-00-00 00:00:00' AND unavailable = '0' ORDER BY last_night ASC LIMIT $offset, $per_page");
if($query->num_rows() > 0)
{
foreach ($query->result() as $row)
{
$bookings[$row->id] = array(
'id' => $row->id,
'check_in' => $row->check_in,
'last_night' => $row->last_night,
'unit' => $row->unit,
'guest' => $row->guest,
'unavailable' => $row->unavailable,
'pending' => $row->pending,
'hash' => $row->hash,
'created' => $row->created,
);
}
return $bookings;
}
}
?>
I think I have found a problem (on my system, at least). I believe the problem lies with the use of the deprecated mime_content_type php function.
From upload.php CI version 2.1 lines 1019 - 1068
protected function _file_mime_type($file)
{
// Use if the Fileinfo extension, if available (only versions above 5.3 support the FILEINFO_MIME_TYPE flag)
if ( (float) substr(phpversion(), 0, 3) >= 5.3 && function_exists('finfo_file'))
{
$finfo = new finfo(FILEINFO_MIME_TYPE);
if ($finfo !== FALSE) // This is possible, if there is no magic MIME database file found on the system
{
$file_type = $finfo->file($file['tmp_name']);
/* According to the comments section of the PHP manual page,
* it is possible that this function returns an empty string
* for some files (e.g. if they don't exist in the magic MIME database)
*/
if (strlen($file_type) > 1)
{
$this->file_type = $file_type;
return;
}
}
}
// Fall back to the deprecated mime_content_type(), if available
if (function_exists('mime_content_type'))
{
$this->file_type = @mime_content_type($file['tmp_name']);
return;
}
/* This is an ugly hack, but UNIX-type systems provide a native way to detect the file type,
* which is still more secure than depending on the value of $_FILES[$field]['type'].
*
* Notes:
* - a 'W' in the substr() expression bellow, would mean that we're using Windows
* - many system admins would disable the exec() function due to security concerns, hence the function_exists() check
*/
if (DIRECTORY_SEPARATOR !== '\\' && function_exists('exec'))
{
$output = array();
@exec('file --brief --mime-type ' . escapeshellarg($file['tmp_path']), $output, $return_code);
if ($return_code === 0 && strlen($output[0]) > 0) // A return status code != 0 would mean failed execution
{
$this->file_type = rtrim($output[0]);
return;
}
}
$this->file_type = $file['type'];
}
I am running php 5.2.17 so the first IF (line 1022) fails. mime_content_type exists in 5.2.17 so the second if (line 1042) executes. $this->file_type is set using the mime_content_type function.
My server passes a random file name for the ‘tmp_name’ with no file extension. I am uploading docx files and my browser passes the correct mime type. However, the mime_content_type function returns plain text mime type. This causes the entire upload function to fail.
My solution: revert to upload.php from 2.0.1.
I don’t know what the best way would be to detect mime type. The danger of using the browser’s data is that it could be hacked allowing the user to upload potentially dangerous files.
Obviously this problem goes away if you are using 5.3+. Unfortunately, I had a hard enough time getting my host to move from 4.+ to 5.+ so I am not holding my breath.
