How to run an function in config file ?
when i try this, i getting an error like this
Fatal error: Call to undefined function setting() in C:\wamp\www\urunsite\application\config\site.php on line 7
my config file
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
// default language
$config['lang'] = 'tr';
// Default user role id
$config['default_role'] = setting('company', 'name');
/* End of file site.php */
the setting() function is auto loading.
please help me.
Config files are loaded early in execution, but you should have no problem running any functions there as long as they have been defined. If you need access to functions that aren't defined at config load time, you have no choice but to load the config file manually instead of automatically, or use a hook to load the needed resources. You will have to use the latter if you want to run helper functions in a core config file, custom config files are usually loaded on demand so it's a bit easier.
setting() isn't a valid function.. If it's your own custom function from a model file or elsewhere, you're not giving this config file proper access to that function.
You said that the setting() function is autoloading, but how is it being autoloaded? Is it from a custom Library? Helper? Model? Depending on which it is, you would need to call the function with:
$this->library_name->setting('company', 'name');
or
$this->model_name->setting('company', 'name');
etc.

Installed crabbley/fpdf-laravel as per instructions. Tried some sample code as follows:
$pdf= app('FPDF');
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Swordsmen Class Times');
$pdf->Output();
While the instantiation of fpdf is different from the samples in the tutorials, all works as expected and the pdf is displayed in the browser. I got this working sample from the crabbley packagist.org/packages/crabbly/fpdf-laravel readme under 'usage'. The 'usage' instructions also provide an alternative instantiation viz: $pdf = new Crabbly\FPDF\FPDF;
The tutorial samples use something slightly different again, ie
require('fpdf.php');
x=new FPDF();
and thus are a little different. When I changed it to be the same as the tutorial, all I changed was the instantiation line from
$pdf= app('FPDF');
to
$pdf = new FPDF('L', 'mm','A4');
and I get the error 'Class 'App\Http\Controllers\FPDF' not found'. I do not understand the difference between the different forms of instantiation and not sure what is going on but I need the latter format so I can set page orientation etc. I also tried the usage format as described above with the same sort of error, ie new Crabbly\FPDF\FPDF not found.
I have tried the require statement but FPDF is not found and I am unsure where to point 'require' to.
Installation consisted of:
composer require crabbly/fpdf-laravel
add Crabbly\FPDF\FpdfServiceProvider::class to config/app.php in the providers section
Any suggestions will be appreciated.
You are using an implementation for the Laravel framework that binds an instance of FPDF to the service container. Using app('FPDF') returns you a new instance of FPDF, which is pretty much the same what new FPDF() would do.
The require way of using it is framework agnostic and would be the way to use FPDF if you are just using a plain PHP script. While you could use this way with Laravel too, why would you want to do that?
The reason the require does not work, by the way, is that the fpdf.php file is not found from where you call it. It would be required to sit in the same directory unless you give it a path. Considering you installed it using composer, the fpdf.php script, if any, should sit inside the vendor directory.
However, just go with using the service container. The line $pdf = new FPDF('L', 'mm','A4'); just creates a new instance of the FPDF class and initializes it by passing arguments to the constructor, these being 'L' for landscape orientation, 'mm' for the measurement unit, and 'A4' for the page size. Without knowing the package you use and having testing it, you should also be able to set them equivalently by calling:
$pdf = app('FPDF', ['L', 'mm', 'A4']);
Hope that helps!
How can I dynamically embed an inline-CSS that was entered via the back office. There're only two register methods available for registering assets in Prestashop.
public function hookDisplayHeader()
{
$this->context->controller->registerJavascript('id', 'path/to/file.js');
$this->context->controller->registerStylesheet('id', 'path/to/file.css');
}
The registerStylesheet method has an option called inline, but that requires the content to be in an existing file first. While I have the CSS code stored in the configurations.
And trying to echo the content in hookDisplayHeader() results in it being printed above the <html> open tag.
Create a TPL file in the hooks directory of your module.
Then get the CSS code value from configurations in hookDisplayHeader() function and pass it to smarty:
$custom_css = `GET CUSTOM CSS FROM CONFIG`;
$this->smarty->assign('yourcustomcss', $custom_css);
return $this->display(__FILE__, 'dummy_file.tpl');
Then in the TPL file: dummy_file.tpl
{if isset($yourcustomcss)}
<style>{$yourcustomcss nofilter}</style>
{/if}
The TPL file is supposed to be in the following directory:
/yourmodule/views/templates/hook/dummy_file.tpl
I am very new to ExtJS 4 and I have a problem extending a class. I have these files:
UsersWindow.js
Ext.define('MyDesktop.UserModel', {
extend: 'Ext.data.Model',
/* ... */
}
Ext.define('MyDesktop.UsersWindow', {
/* ... */
}
DealersWindow.js
Ext.define('MyDesktop.DealerModel', {
extend: 'MyDesktop.UserModel',
/* ... */
}
Ext.define('MyDesktop.DealersWindow', {
extend: 'MyDesktop.UsersWindow',
/* ... */
}
When I run the application, everything works as expected, however, I have this ajax call:
/UserModel.js?_dc=1379135132790
that gives a 404, and then a error parsing the javascript. I want to understand why ExtJS making this call ? Does every class should be in there own file ? Can I configure ExtJS to no look for this file ?
Thank you for your help.
Yes, every class has to be in its own file for the Ext Loader to work properly. Beside, the name of the file should be the same as the class, and its path should match the namespace.
What happens here is that the extend: 'MyDesktop.UserModel' line prompts the Ext.Loader to load the UserModel class, that it expects to find in the UserModel.js file in the root path for the MyDesktop namespace, which seems to be configured as the root directory of the application...
You can configure root source directories for different namespaces with the paths property of the Loader, or the one of the Application.
If you want to prevent Ext from trying to load this file, you will have to disable the Loader, and then you will have to include all your source files as <script> tags in your HTML. I think this will also make it impossible to compile a production build of the application later.
Alternatively, you could put your definition of MyDesktop.UserModel above the definition of MyDesktop.DealerModel, either in the same file or a file before it in the script tags. Note that even this may not work, because the requires option in your classes definitions may change the order in which the class definition are actually executed. Then again, that will probably break the build process ultimately...
In short, you should not try to work again the framework's expectations. Especially when you consider that the 1:1 mapping between class names and the file system is standard practice in about every OO language out there...
I got custom.php (inside config folder) with code like below
$config['myurl'] = 'somesite.com';
I got config.php ( standard CI ), I want to set the base_url using the value from custom.php, like this
$config['base_url'] = $this->config->item('myurl');
Doing that I got the error
Using $this when not in object context in /Volumes/HD 2/work/vnl/app/config/config.php on line 18
Whats the right code for this purpose?
This is not going to work there. The $this that you would want to use there is a controller instance and that is not created yet when the standard application/config/config.php loads.
You can try to add a pre_system hook (that's loaded right before the config object) and include in some helper function that can be called and return the desired value in the application/config/config.php. The usual constants like APPPATH will be available then.
If you can make this config variable a constant that can work too (just put the define() inside application/config/constants.php). Since the config file is just a regular php source file, you can have conditionals here too if you must.
You can just work with the arrays.
In your custom config file
$config['myurl'] = 'myurl.com';
$config['base_url'] = &$config['myurl'];
This will change the default base_url once the custom config file is loaded, you can also just reset the base_url element in your custom config, however in my opinion it is not recommended to reset the base url in another config file as later in the project you could lose track of where it is set, why not set it (and maybe use conditions) in the main config file?
I cannot for the life of me figure out how to call a shell from a controller.
We have a background process that packages up data in a .pdf, and we don't want to bog down the page loads waiting for this to occur, so we want to put all this processing in a shell.
I've figured out how to pass values to a shell with $this->args
I know you can use App::import('Shell','TestShell')... but after that I am lost.
How do I call the main() function of the shell within a controller?
In Cake 1.3, I was able to get it working by doing the following:
App::import('Shell', 'Shell');
App::Import('Vendor', array('shells/shell_title'));
$myShell = new ShellTitleShell(new Object());
$myShell->initialize();
$myShell->someAction();
I should be more focused reading the question :/
Could do it in Cake2, not sure how different would it be for 1.3. :?
<?php
App::import('Console/Command', 'AppShell');
App::import('Console/Command', 'HelloWorldShell');
$h = new HelloWorldShell();
$h->dispatchMethod('main');
?>
Windows:
If you do not have your environment variables set you will need to provide location of PHP executable.
C:\wamp\bin\php\php_v\php.exe C:\wamp\www\cakephp\cake\console\cake.php test this_arg_0 this_arg_1
Linux:
You may already have your php location defined. If not, you may need to export it to your $PATH or provide full path to php
php /var/www/html/cakephp/cake/console/cake.php test this_arg_0 this_arg_1
main() function will be called by default.
Hope it helps!
