I'm writing a custom helper that extends HtmlHelper and overriding the \HtmlHelper::image() method to calculate the image dimensions and add them as HTML attributes. What I have so far works fine for regular pictures:
public function image($path, $options = array()) {
if (!array_key_exists('width', $options) && !array_key_exists('height', $options)) {
$stamp = Configure::read('Asset.timestamp');
Configure::write('Asset.timestamp', false);
$path = $this->assetUrl($path, $options + array('pathPrefix' => Configure::read('App.imageBaseUrl')));
list($width, $height) = #getimagesize(rtrim(WWW_ROOT, '\\/') . $path);
if (!is_null($width)) {
$options['width'] = $width;
}
if (!is_null($height)) {
$options['height'] = $height;
}
Configure::write('Asset.timestamp', $stamp);
}
return parent::image($path, $options);
}
… but has these flaws:
Pictures from plug-ins can't be located on disk (and they should), e.g.:
echo $this->Html->image('/debug_kit/img/cake.icon.png', array('alt' => 'CakePHP'));
… produces this file system path:
…\src\webroot/debug_kit/img/cake.icon.png
… thus getimagesize() fails because actual location is:
…\src\Plugin\DebugKit\webroot\img\cake.icon.png"
External pictures (which should be ignored) go through the full process:
echo $this->Html->image('http://placekitten.com/200/300');
…\src\webroothttp://placekitten.com/200/300
I've been looking for a builtin method to convert a CakePHP picture URL (in any format accepted by \HtmlHelper::image() into a file system path (o something like null when doesn't apply) but I couldn't find any. Native features that need a disk path, such as \Helper::assetTimestamp() are wrapped in tons of non-reusable code.
Is there an elegant solution?
I'd say that there are pretty much only 3 options:
Submit a patch to add asset filesystem path retrieval functionality to the core.
Copy a lot of code from the helper (assetUrl(), webroot(), and assetTimestamp()).
Use web requests for local URLs (ideally combined with caching).
Try using DS rather than using \ or /, they sometime can cause problems with the OS.
DS is directory separator provided by cakephp Short for PHP’s DIRECTORY_SEPARATOR, which is / on Linux and \ on Windows.

I am creating an invoice on users desired package selection. The pdf file is being created (but it takes some time), while the code checks for the file. The file exists. Here is the address of the file;
C:/wamp/www/proposal/file/invoice/Basic_52_60.pdf
This is the correct path to the file. I am passing this path to the function in another controller as;
redirect('email/email_invoice/'.$file);
When I tested the file path in email_invoice function, it displayed only c:
c:
The slashes in the path are not transferred. I don't know exactly what is the problem.
CodeIgniter considers each segment of the URL a parameter after the controller and method. So you are essentially passing 7 variables to the Email::email_invoice() method.
You could use some sort of encoding to pass it as one variable and then decode it on the other side such as:
$file = base64_encode($file);
redirect('email/email_invoice/' . $file);
Then in Email.php:
public function email_invoice($file) {
$file = base64_decode($file);
}
Or you could pass it as a get parameter:
redirect('email/email_invoice/?file=' . $file);
public function email_invoice() {
$file = $this->input->get('file');
}
The latter requires the $_GET array to be enabled which it is not by default.
UPDATE - Using Flashdata
Based on some of the comments I thought I would update this answer. base64_encode() can result in characters that will break the URL so you would need to use:
$file = urlencode(base64_encode($file));
redirect('email/email_invoice/' . $file);
And on the other side:
public function email_invoice($file) {
$file = urldecode(base64_decode($file));
}
As the OP pointed out $_GET variables can be manipulated leaving you open to directory traversal attacks or other vulnerabilities. Even if done right you would need extra code for security. Encoding can easily be spotted and altered.
File paths probably shouldn't be carried around in the URL. POST data can be manipulated also even if it is less obvious. Security through obscurity is not security at all. A better approach would be to use flashdata.
$this->session->set_flashdata('email_invoice_pdf', $file);
redirect('email/email_invoice/');
Then in your controller:
public function email_invoice() {
$file = $this->session->flashdata('email_invoice_pdf');
}
That's it. The session was used to carry the file path to the next page request, but after that it is gone.
I'm trying to create a new node for every file thats in a specific folder using Drupal 7.
A good example of what I'm trying to create is Youtube.
When I paste a video with the .mp4 extension in a specific folder, I want Drupal to scan that folder (I will tell Drupal when to scan, so this doesn't have to happen automatically), and create a node with that video in it. I will manually set the title, description, etc... myself using the admin interface, and publish it.
I know my way around in Drupal, and its modules, but I'm not an expert. I've been googling for awhile now and the only thing I could find was:
file_scan_directory($dir, $mask, $options = array(), $depth = 0)
I'm not asking for a complete copy/paste solution, I was just hoping someone could give me some tips, useful links or tutorials on how to do this.
To create a node for each video file you find in a directory, you can use code similar to the following one.
foreach (file_scan_directory($dir, '*.mp4', array('recurse' => FALSE) as $uri => $info) {
$body_text = 'Build the body text.';
$node = new stdClass();
$node->type = $node_type;
node_object_prepare($node);
$node->title = 'Node Created Programmatically on ' . date('c');
$node->language = LANGUAGE_NONE;
$node->body[$node->language][0]['value'] = $body_text;
$node->body[$node->language][0]['summary'] = text_summary($body_text);
$node->body[$node->language][0]['format'] = 'full_html';
node_save($node);
}
i have a form that contains two file element with unique name. i want to reach each file element from Zend_File_Transfer_Adapter_Http(); how can i do that?
if i use
$apt = new Zend_File_Transfer_Adapter_Http();
.
.
$apt->receive();
two files have been uploaded. but i execute different queries for each file element.
for example
$smallPic = small pic name that i get from input smallPic
i execute
update products set smallPic = '$smallPic'
and for large pic
$largePic = large pic name that i get from input largePic
i execute
update products set largePic = '$largePic'
how can i reach each input file element with $apt ?
Here is some code I have used in the past to receive multiple files from a Zend_Form where many of the file upload fields were dynamic and not part of the form.
Since you know the names of the two file uploads, you can also say $apt->getFileInfo('my_file');
$apt = new Zend_File_Transfer_Adapter_Http();
$files = $apt->getFileInfo();
foreach($files as $file => $fileInfo) {
if ($apt->isUploaded($file)) {
if ($apt->isValid($file)) {
if ($apt->receive($file)) {
$info = $apt->getFileInfo($file);
$tmp = $info[$file]['tmp_name'];
$data = file_get_contents($tmp);
// here $tmp is the location of the uploaded file on the server
// var_dump($info); to see all the fields you can use
}
}
}
}
Hope that helps.
I'm researching hours and hours, but I could not find any clear, efficient way to make it :/
I have a codeigniter base website in English and I have to add a Polish language now. What is the best way to make my site in 2 language depending visitor selection?
is there any way to create array files for each language and call them in view files depends on Session from lang selection? I don't wanna use database.
Appreciate helps! I'm running out of deadline :/ thanks!!
Have you seen CodeIgniter's Language library?
The Language Class provides functions
to retrieve language files and lines
of text for purposes of internationalization.
In your CodeIgniter system folder you'll
find one called language containing sets
of language files. You can create your
own language files as needed in order
to display error and other messages in
other languages.
Language files are typically stored in
your system/language directory. Alternately
you can create a folder called language
inside your application folder and store
them there. CodeIgniter will look first
in your application/language directory.
If the directory does not exist or the
specified language is not located there
CI will instead look in your global
system/language folder.
In your case...
you need to create a polish_lang.php and english_lang.php inside application/language/polish
then create your keys inside that file (e.g. $lang['hello'] = "Witaj";
then load it in your controller like $this->lang->load('polish_lang', 'polish');
then fetch the line like $this->lang->line('hello'); Just store the return value of this function in a variable so you can use it in your view.
Repeat the steps for the english language and all other languages you need.
Also to add the language to the session, I would define some constants for each language, then make sure you have the session library autoloaded in config/autoload.php, or you load it whenever you need it. Add the users desired language to the session:
$this->session->set_userdata('language', ENGLISH);
Then you can grab it anytime like this:
$language = $this->session->userdata('language');
In the controller add following lines when you make the cunstructor
i.e, after
parent::Controller();
add below lines
$this->load->helper('lang_translate');
$this->lang->load('nl_site', 'nl'); // ('filename', 'directory')
create helper file lang_translate_helper.php with following function and put it in directory system\application\helpers
function label($label, $obj)
{
$return = $obj->lang->line($label);
if($return)
echo $return;
else
echo $label;
}
for each of the language, create a directory with language abbrevation like en, nl, fr, etc., under
system\application\languages
create language file in above (respective) directory which will contain $lang array holding pairs label=>language_value as given below
nl_site_lang.php
$lang['welcome'] = 'Welkom';
$lang['hello word'] = 'worde Witaj';
en_site_lang.php
$lang['welcome'] = 'Welcome';
$lang['hello word'] = 'Hello Word';
you can store multiple files for same language with differently as per the requirement
e.g, if you want separate language file for managing backend (administrator section) you can use it in controller as $this->lang->load('nl_admin', 'nl');
nl_admin_lang.php
$lang['welcome'] = 'Welkom';
$lang['hello word'] = 'worde Witaj';
and finally
to print the label in desired language, access labels as below in view
label('welcome', $this);
OR
label('hello word', $this);
note the space in hello & word you can use it like this way as well :)
whene there is no lable defined in the language file, it will simply print it what you passed to the function label.
I second Randell's answer.
However, one could always integrate a GeoIP such as http://www.maxmind.com/app/php
or http://www.ipinfodb.com/. Then you can save the results with the codeigniter session class.
If you want to use the ipinfodb.com api You can add the ip2locationlite.class.php file to your codeigniter application library folder and then create a model function to do whatever geoip logic you need for your application, such as:
function geolocate()
{
$ipinfodb = new ipinfodb;
$ipinfodb->setKey('API KEY');
//Get errors and locations
$locations = $ipinfodb->getGeoLocation($this->input->ip_address());
$errors = $ipinfodb->getError();
//Set geolocation cookie
if(empty($errors))
{
foreach ($locations as $field => $val):
if($field === 'CountryCode')
{
$place = $val;
}
endforeach;
}
return $place;
}
For easier use CI have updated this so you can just use
$this->load->helper('language');
and to translate text
lang('language line');
and if you want to warp it inside label then use optional parameter
lang('language line', 'element id');
This will output
// becomes <label for="form_item_id">language_key</label>

I've used Wiredesignz's MY_Language class with great success.
I've just published it on github, as I can't seem to find a trace of it anywhere.
https://github.com/meigwilym/CI_Language
My only changes are to rename the class to CI_Lang, in accordance with the new v2 changes.
When managing the actual files, things can get out of sync pretty easily unless you're really vigilant. So we've launched a (beta) free service called String which allows you to keep track of your language files easily, and collaborate with translators.
You can either import existing language files (in PHP array, PHP Define, ini, po or .strings formats) or create your own sections from scratch and add content directly through the system.
String is totally free so please check it out and tell us what you think.
It's actually built on Codeigniter too! Check out the beta at http://mygengo.com/string
Follow this https://github.com/EllisLab/CodeIgniter/wiki/CodeIgniter-2.1-internationalization-i18n
its simple and clear, also check out the document # http://ellislab.com/codeigniter/user-guide/libraries/language.html
its way simpler than
I am using such code in config.php:
$lang = 'ru'; // this language will be used if there is no any lang information from useragent (for example, from command line, wget, etc...
if (!empty($_SERVER['HTTP_ACCEPT_LANGUAGE'])) $lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'],0,2);
$tmp_value = $_COOKIE['language'];
if (!empty($tmp_value)) $lang = $tmp_value;
switch ($lang)
{
case 'ru':
$config['language'] = 'russian';
setlocale(LC_ALL,'ru_RU.UTF-8');
break;
case 'uk':
$config['language'] = 'ukrainian';
setlocale(LC_ALL,'uk_UA.UTF-8');
break;
case 'foo':
$config['language'] = 'foo';
setlocale(LC_ALL,'foo_FOO.UTF-8');
break;
default:
$config['language'] = 'english';
setlocale(LC_ALL,'en_US.UTF-8');
break;
}
.... and then i'm using usualy internal mechanizm of CI
o, almost forget! in views i using buttons, which seting cookie 'language' with language, prefered by user.
So, first this code try to detect "preffered language" setted in user`s useragent (browser). Then code try to read cookie 'language'. And finaly - switch sets language for CI-application
you can make a function like this
function translateTo($language, $word) {
define('defaultLang','english');
if (isset($lang[$language][$word]) == FALSE)
return $lang[$language][$word];
else
return $lang[defaultLang][$word];
}
Friend, don't worry, if you have any application installed built in codeigniter and you wanna add some language pack just follow these steps:
1. Add language files in folder application/language/arabic (i add arabic lang in sma2 built in ci)
2. Go to the file named setting.php in application/modules/settings/views/setting.php. Here you find the array
<?php /*
$lang = array (
'english' => 'English',
'arabic' => 'Arabic', // i add this here
'spanish' => 'Español'
Now save and run the application. It's worked fine.
