I have the below content in my DB-
<p>This is dummy content for testing</p>
{{LandingPageController::getTest()}}
I want to render that into my view. But when I'm rendering this in Laravel view, this {{LandingPageController::getTest()}} is getting displayed as it is stored in DB.
I want to call the LandingPageController getTest method in my view.
Please suggest me a quick fix for this.
Landing Page Controller
public function getTest(){
return "Hello World!!!";
}
just make the function static
public static function getTest(){
return "Hello World!!!";
}
that's the only way you can call it like this {{LandingPageController::getTest()}} but I do advice not to do that in your blade file this not a good code design. you should do $test = LandingPageController::getTest() in the controller that you return the blade view and pass it like this return view('blade_file_name',compact('test')) and in your blade file just do {{$test}}
PS - if you doing it your controller use the class like this use Path\To\Controller\LandingPageController
Use namespace for that controller in your blade file. example
namespace App\Http\Controllers\LandingPageController;
You can evaluate a string as a php code using the eval() function
eval — Evaluate a string as PHP code
But it is highly discouraged.
The eval() language construct is very dangerous because it allows execution of arbitrary PHP code. Its use thus is discouraged. If you have carefully verified that there is no other option than to use this construct, pay special attention not to pass any user provided data into it without properly validating it beforehand.
You can use a generic string, {test} for example, when saving the content in the storage.
<p>This is dummy content for testing</p>
{test}
Then whenever you need to display the actual content, you can simply replace the generic string with the real value. You'll have this line in your blade file:
{{ str_replace('{str}', "Hello World", $content) }}
Take a look at Helper. You can call helper function in view to render your text or html
Got the solution, achieve the functionality with "laravel-shortcodes".
Found a very good tutorial on laravel-shortcodes like wordpress

I am trying to figure out how to do the equivalent of the following in Laravel that I would do in CodeIgniter all the time to build views:
$section = $this->load->view('pages/about', $data, TRUE);
This would allow me to echo $section in another view file and then when that view was called the normal way, it would render it. I am not sure how to do something like this in Laravel.
UPDATE
I figured it out. What I was needing was Laravel's HtmlString class to take a string and convert it to html markup to the view file.
You would need to use the View Facade, so make sure to include it with an "Use" statement in your Controller, but basically is this:
$html = View::make('pages/about', $data)->render();
The render() method will just render the view in HTML, instead of returning it as a Response object like the view() helper function does.
There are several ways to do so, try this:
return view('admin.profile', $data);
Read through this doc:
https://laravel.com/docs/5.5/views
I didn't deal with render method yet !!
is it for blade template ?
I have to pass dynamic data in blade.php file dynamically.
Given that you've tagged the question with Blade, I'll assume you mean render inside Laravel's View class.
Illuminate\View\View::render() returns the string contents of the view. It is also used inside the class' __toString() method which allows you to echo a View object.
// example.blade.php
Hello, World!
// SomeController.php
$view = view('example');
echo $view->render(); // Hello, World!
echo $view; // Hello, World!
Laravel typically handles this for you, I.e. calls render or uses the object as a string when necessary.
Blade's #include('viewname') directive will load the view file and call the render method behind the scenes for example.
You may use it yourself when you want to get the compiled view to perform some subsequent action. Occasionally I have called render explicitly rather than to string if the view itself is causing an exception and in PHP explains
Fatal error: Method a::__toString() must not throw an exception in /index.php on line 12
Calling render() in the above case gives a more useful error message.
Render(), when applied to a view, will generate the corresponding raw html and store the result in a variable.
Typical reasons for which I use render are:
When converting pages to pdf (ex. using dompdf, pass this into loadhtml()), returning HTML content to ajax calls
You can get php blade file with passing dynamic value in a string form
Like this
Blade
<link rel="apple-touch-icon" sizes="60x60" href="{{$url}}/assets/images/favicon/apple-icon-60x60.png">
Controller
$html = view('User::html-file',['url'=>'https://stackoverflow.com'])->render();
O/P
<link rel="apple-touch-icon" sizes="60x60" href="https://stackoverflow.com/assets/images/favicon/apple-icon-60x60.png">\r\n
0pposed to ->render() when using DomPDF, you can also use ->toHtml():
$pdf->loadHtml(\view('folderX.bladeY', $data)->toHtml());
We got a shopsystem working with Smarty. I need to pass some Smarty variables to a PHP function and get the return.
What I know and also did so far is the following:
{$order_id|#get_order_total}
So this passes the Smarty Variable "$order_id" to a included PHP file which contains the function get_order_total($order_id) and shows me the return of this function.
Now I need to pass 3 variables to a PHP function. The function would for example look like this:
handleDebit($order, $payCode, $insertId)
Sadly i have not found the right thing so far in smarty documentation. Anyone has ever done this?
If you really need to call the function from within smarty templates, register a wrapper function as smarty-plugin:
<?php
$smarty->registerPlugin("function","handleDebit", "handleDebitSmarty");
function handleDebitSmarty($params, $smarty)
{
return handleDebit($params['order'], $params['payCode'], $params['insertId']);
}
Now you can use it as smarty tag:
{handleDebit order=$blah payCode=$blub insertId=$yeahh}
But you should consider #JonSterling s advice and try to find a way auch that a controller is doing the handleDebit-call and you only handle results/display-stuff in the template.
I am using Yii Framework. In the view, main.php, there is a reference to the $content block
<?php echo $content; ?>
I could not find it anywhere in the model or elsewhere in the demo project. Can someone shed light on this? Or may be this variable is never declared? I have not modified the demo project yet.
The $content value in layout files contains the rendered content of the template specified as the first attribute of the render command. (It's automatically created so I wouldn't use "content" as an additional variable name or it could cause confusion.) The variables that you pass as an additional array argument in the render statement are made available to the template you are calling, not to the layout.
If you have nested layouts, the value of $content cascades from parent to child.
All your controllers are derived from CController class. CController has a function named render which you call it for rendering your views. It works like this:
beforeRender is called.
renderPartial is called on your view file, and its output is stored in $output.
renderFile is called on the layout file, with a parameter named content like this:
$this->render(layoutFile, array('content'=>$output));
So the $content is coming from here. You can see the actual code here: Source code, and documentation here: Documentation
Found answer from Yii Documentation / Layouts,
For example, a layout may contain a header and a footer, and embed the
view in between, like this:
......header here......
<?php echo $content; ?>
......footer here......
where $content stores the rendering result of the view.
It is indeed all the text in one of the view (in my case index.php). $content basically takes the content of view. It is not declared anywhere and it is be default. As the answer said, you should not use declare/use $content in your code.
I think its being set from the controller which is calling this view.
In the controller look for something like the following
$this->render('main', array('content'=>"something here"));
Kohana (and probably other frameworks) allow you get a route and echo its URL, creating routes that are easy to maintain.

Is this OK to have in the view, or should I assign it to a variable, and then pass the view the variable?
Thanks
You aren't performing logic here. This is perfectly acceptable.
Of course your view code would be a bit cleaner if you created a variable in your controller, but this really is fine IMHO.
I find such a concatenation unnecessary. It seems url::base() going to be used in every link on the site. Why not to have a method to add it automatically? Something like Route::url("contact")
And usage of such a construct in the template is OK.
You can create a function or static method for generating urls:
public static function url($routename, array $params = NULL)
{
return url::base().Route::get($routename)->uri($params);
}
