I am loading a template in my current php file using Joomla's loadTemplate function with passing the variables like below
<?php echo $this->loadTemplate('test', array('id' => '10')); ?>
While in the 'test.php', I am not getting this 'id' value. How can I get this?
The loadTemplate function only has one argument, the name of the template (see the API docs).
What usually works for me is assigning the value to a variable on $this, for example $this->myId = 10.

I have file excel.php by the path /resources/lang/en/excel.php
Then in controller I tried to fetch word by key:
use Lang;
echo Lang::get('excel.idEvent');
Also I tried:
dd(echo __('excel.idEvent'));
Whats is right way to do that?
First, your excel.php file must be in the right format:
<?php
return [
'welcome' => 'Welcome to our application'
];
The right way to get it on your blade template in fact it is:
echo __('excel.welcome');
or
echo __('Welcome to our application');
The way to do it on your controller is:
use Lang;
Lang::get('excel.welcome');
If you are not using Facades: use \Illuminate\Support\Facades\Lang;
You can also use the trans() function, ex:
Route::get('/', function () {
echo trans('messages.welcome');
});
If you use JSON translation files, you might have to use __().
Here are all the ways to use:
#lang('...') // only in blade files
__('...')
Lang::get('...')
trans('...')
app('translator')->get('...')
Lang::trans('...')
They all defer to \Illuminate\Translation\Translator::get() eventually.
I am using laravel 5.5. I have created a helper.php in app\Http. I am calling this helper in my blade file by using
{!! Helper::functionName() !!}
this is working fine. but i want to hold this helper result in a variable like
{!! $Result=Helper::functionName() !!}
But currently this is printing this result. How to solve this. please help.
So that i can make any if condition on this $Result.
In my helpers.php
namespace App\Http\Helpers;
class Helper
{
public static function functionName()
{
return "mydata";
}
}
There is no point to use helper like this. You should run the helper in controller and pass calculated data into view. In most cases you shouldn't set any variables in views or make any calculations - those should be passed from controller to view and view should only use them.
In this case, you can use "<?php ?>".
So result:
<?php $Result=Helper::functionName(); ?>
may be this is not possible because in laravel "{{}}" this means echo "" so by default it will print the value. return the value from helper function and use in your blade
I want to add some blade directives.
I have in my service provider
Blade::directive('image', function ($media) {
return "<?php echo {$media->getImageUrl()}; ?>";
});
The blade file contain
#image($media)
the $media variable is an object which use the Media model and which contains a public function getImageUrl()which return a string with the url of the image.
When I execute this code, I have this error message
Fatal error: Call to a member function getImageUrl() on string
The object passed in the Blade directive is considered as a string instead of Media object
Is there any way to use $media as an Mediaobject instead of a string ?
The curly braces should be around $media:
Blade::directive('image', function ($media) {
return "<?php echo {$media}->getImageUrl(); ?>";
});
This compiles to:
<?php echo ($media)->getImageUrl(); ?>
As far as I know Blade directives only accept one expression as a string, including the function call braces. So the expression received by the directive is:
"($media)"
After changing directives you should clear the compiled views because Blade is caching the directives, so you would not see your changes taking affect.
I have a problem when i try to add other parameter to URL.
before i use Codeigniter i add those parameters using JavaScript like this
test
but when i tried to do it with Codeigniter i don't know how.
<?php echo anchor("home/index/param1","test"); ?>
as i said i want to add this parameter for example my URL looks like this
home/index/param2
so when i click on test i want the URL to be like this
home/index/param2/param1
Take a look at CodeIgniter's URL Helper Documentation
The first parameter can contain any segments you wish appended to the URL. As with the site_url() function above, segments can be a string or an array.
For your example, you could try:
<?php
$base_url = 'home/index/';
$param1 = 'param1';
$param2 = 'param2';
$segments = array($base_url, $param1, $param2);
echo anchor($segments,"test");
?>
You can't do that with the form helper, you have to use your js function again :
echo anchor("home/index/param2", "test", array("onClick" => "javascript:addParam(window.location.href, 'display', 'param1');"));
It will produce :
test
But I don't see the point of dynamically change the href on the click event. Why don't you set it directly at the beginning ?
echo anchor("home/index/param2/param1", "test");
I have a problem understanding how variables work inside the Laravel templating system, Blade.
I set the variables in the controller, I can see them in the first view I make, but not inside the next one.
I'm using a master.blade.php file that holds the header and footer of the page, yielding the content in the middle. I can use the variable inside the master.blade.php file, but not inside the content blade file (variable undefined).
For example, for the contact page:
CONTROLLER FUNCTION:
$this->data['page'] = "contact";
$this->layout->content = View::make('pages.contact');
$this->layout->with('data', $this->data);
MASTER.BLADE.PHP:
if ($data['page'] == 'contact')
{ //do something, it works }
#yield('content')
CONTACT.BLADE.PHP:
if ($data['page'] == 'contact')
{// do something. ErrorException Undefined variable: data}
Am I missing something or is it a known restriction?
Thanks!
The problem was that I was passing the variables only to the layout:
Instead of:
$this->layout->content = View::make('pages.contact');
$this->layout->with('data', $this->data);
I fixed it using:
$this->layout->content = View::make('pages.contact', array('data' => $this->data));
$this->layout->with('data', $this->data);
This way passing the variables to the layout, but also to that particular view.
Hope it helps someone.
