In order to see the path to template in generated html source code for debuggin purposes I used the following code snippet in the
app/code/core/Mage/Core/Block/Template.php
/**
* Render block
*
* #return string
*/
public function renderView()
{
$this->setScriptPath(Mage::getBaseDir('design'));
$showDebug = true;
if (!$showDebug) {
$html = $this->fetchView($this->getTemplateFile());
}
else {
$template = $this->getTemplateFile();
$tagName = 'template_'.current(explode('.',end(explode('/',$template))));
$html = '<'.$tagName.'><!-- '.$template.' -->';
$html .= $this->fetchView($template);
$html .= '<!--/ '.$template.' --></'.$tagName.'>';
}
return $html;
}
but now in the error logs I see the following:
2010-12-13T21:55:35+00:00 ERR (3): Strict Notice: Only variables should be passed by reference in /app/code/core/Mage/Core/Block/Template.php on line 245
How should this be referenced in order to avoid this error?
Pretty sure your problem is this line
$tagName = 'template_'.current(explode('.',end(explode('/',$template))));
The end and current methods accept an array variable as a paramater, passed by reference. You're passing the result of a function call, which PHP doesn't like. Assuming that snippet is trying to get an extension-less template name, try this instead
$parts = pathinfo($template);
$tagName = $parts['filename'];
Install the Developer Toolbar extension instead. Or turn on Template Hints from the Admin.

I'm trying to get rendered twig content in a plugin controller. I'm using CmsCompoundObject to load a partial but it's throwing an error.
$theme = Theme::getActiveThemeCode();
$markup = CmsCompoundObject::load($theme, "partials/test.htm")->getTwigContent();
The from property is invalid, make sure that Cms\Classes\CmsCompoundObject has a string value for its $dirName property (use '' if not using directories)
../october/rain/src/Halcyon/Builder.php line 309
Looking at the code, this is where it's throwing the error:
/**
* #return array
*/
protected function runSelect()
{
if (!is_string($this->from)) {
throw new ApplicationException(sprintf("The from property is invalid, make sure that %s has a string value for its \$dirName property (use '' if not using directories)", get_class($this->model)));
}
if ($this->selectSingle) {
list($name, $extension) = $this->selectSingle;
return $this->datasource->selectOne($this->from, $name, $extension);
}
}
$theme is a string and not empty, it properly gets the current theme so I'm not sure why it's saying invalid.
OctoberCMS Slack channel helped me find the solution.
First was to use Partial instead of CmsCompoundObject and the 2nd was to remove "partials/" from the path name as the Partial class already knows to look in that directory.
$theme = Theme::getActiveTheme();
$markup = Partial::load($theme, "test.htm")->getTwigContent();
How can I compile a blade template from a string rather than a view file, like the code below:
<?php
$string = '<h2>{{ $name }}</h2>';
echo Blade::compile($string, array('name' => 'John Doe'));
?>
http://paste.laravel.com/ujL
I found the solution by extending BladeCompiler.
<?php namespace Laravel\Enhanced;
use Illuminate\View\Compilers\BladeCompiler as LaravelBladeCompiler;
class BladeCompiler extends LaravelBladeCompiler {
/**
* Compile blade template with passing arguments.
*
* #param string $value HTML-code including blade
* #param array $args Array of values used in blade
* #return string
*/
public function compileWiths($value, array $args = array())
{
$generated = parent::compileString($value);
ob_start() and extract($args, EXTR_SKIP);
// We'll include the view contents for parsing within a catcher
// so we can avoid any WSOD errors. If an exception occurs we
// will throw it out to the exception handler.
try
{
eval('?>'.$generated);
}
// If we caught an exception, we'll silently flush the output
// buffer so that no partially rendered views get thrown out
// to the client and confuse the user with junk.
catch (\Exception $e)
{
ob_get_clean(); throw $e;
}
$content = ob_get_clean();
return $content;
}
}
Small modification to the above script.
You can use this function inside any class without extending the BladeCompiler class.
public function bladeCompile($value, array $args = array())
{
$generated = \Blade::compileString($value);
ob_start() and extract($args, EXTR_SKIP);
// We'll include the view contents for parsing within a catcher
// so we can avoid any WSOD errors. If an exception occurs we
// will throw it out to the exception handler.
try
{
eval('?>'.$generated);
}
// If we caught an exception, we'll silently flush the output
// buffer so that no partially rendered views get thrown out
// to the client and confuse the user with junk.
catch (\Exception $e)
{
ob_get_clean(); throw $e;
}
$content = ob_get_clean();
return $content;
}
For anyone still interested in this, they've added it to Laravel 9
use Illuminate\Support\Facades\Blade;
return Blade::render('Hello, {{ $name }}', ['name' => 'Julian Bashir']);
https://laravel.com/docs/9.x/blade#rendering-inline-blade-templates
I just stumbled upon the same requirement! For me, i had to fetch a blade template stored in DB & render it to send email notifications.
I did this in laravel 5.8 by kind-of Extending \Illuminate\View\View. So, basically i created the below class & named him StringBlade (I couldn't find a better name atm :/)
<?php
namespace App\Central\Libraries\Blade;
use Illuminate\Filesystem\Filesystem;
class StringBlade implements StringBladeContract
{
/**
* #var Filesystem
*/
protected $file;
/**
* #var \Illuminate\View\View|\Illuminate\Contracts\View\Factory
*/
protected $viewer;
/**
* StringBlade constructor.
*
* #param Filesystem $file
*/
public function __construct(Filesystem $file)
{
$this->file = $file;
$this->viewer = view();
}
/**
* Get Blade File path.
*
* #param $bladeString
* #return bool|string
*/
protected function getBlade($bladeString)
{
$bladePath = $this->generateBladePath();
$content = \Blade::compileString($bladeString);
return $this->file->put($bladePath, $content)
? $bladePath
: false;
}
/**
* Get the rendered HTML.
*
* #param $bladeString
* #param array $data
* #return bool|string
*/
public function render($bladeString, $data = [])
{
// Put the php version of blade String to *.php temp file & returns the temp file path
$bladePath = $this->getBlade($bladeString);
if (!$bladePath) {
return false;
}
// Render the php temp file & return the HTML content
$content = $this->viewer->file($bladePath, $data)->render();
// Delete the php temp file.
$this->file->delete($bladePath);
return $content;
}
/**
* Generate a blade file path.
*
* #return string
*/
protected function generateBladePath()
{
$cachePath = rtrim(config('cache.stores.file.path'), '/');
$tempFileName = sha1('string-blade' . microtime());
$directory = "{$cachePath}/string-blades";
if (!is_dir($directory)) {
mkdir($directory, 0777);
}
return "{$directory}/{$tempFileName}.php";
}
}
As you can already see from the above, below are the steps followed:
First converted the blade string to the php equivalent using \Blade::compileString($bladeString).
Now we have to store it to a physical file. For this storage, the frameworks cache directory is used - storage/framework/cache/data/string-blades/
Now we can ask \Illuminate\View\Factory native method 'file()' to compile & render this file.
Delete the temp file immediately (In my case i didn't need to keep the php equivalent file, Probably same for you too)
And Finally i created a facade in a composer auto-loaded file for easy usage like below:
<?php
if (! function_exists('string_blade')) {
/**
* Get StringBlade Instance or returns the HTML after rendering the blade string with the given data.
*
* #param string $html
* #param array $data
* #return StringBladeContract|bool|string
*/
function string_blade(string $html, $data = [])
{
return !empty($html)
? app(StringBladeContract::class)->render($html, $data)
: app(StringBladeContract::class);
}
}
Now i can call it from anywhere like below:
<?php
$html = string_blade('<span>My Name is {{ $name }}</span>', ['name' => 'Nikhil']);
// Outputs HTML
// <span>My Name is Nikhil</span>
Hope this helps someone or at-least maybe inspires someone to re-write in a better way.
Cheers!
I'm not using blade this way but I thought that the compile method accepts only a view as argument.
Maybe you're looking for:
Blade::compileString()
It's a old question. But I found a package which makes the job easier.
Laravel Blade String Compiler renders the blade templates from the string value. Check the documentation on how to install the package.
Here is an example:
$template = '<h1>{{ $name }}</h1>'; // string blade template
return view (['template' => $template], ['name' => 'John Doe']);
Note: The package is now updated to support till Laravel 6.
I know its pretty old thread, but today also requirement is same.
Following is the way I solved this on my Laravel 5.7 (but this will work with any laravel version greater than version 5), I used the knowledge gained from this thread and few other threads to get this working (will leave links to all threads at the end, if this help up-vote those too)
I added this to my helper.php (I used this technique to add helper to my project, but you can use this function directly as well)
if (! function_exists('inline_view')) {
/**
* Get the evaluated view contents for the given blade string.
*
* #param string $view
* #param array $data
* #param array $mergeData
* #return \Illuminate\View\View|\Illuminate\Contracts\View\Factory
*/
function inline_view($view = null, $data = [], $mergeData = [])
{
/* Create a file with name as hash of the passed string */
$filename = hash('sha1', $view);
/* Putting it in storage/framework/views so that these files get cleared on `php artisan view:clear*/
$file_location = storage_path('framework/views/');
$filepath = storage_path('framework/views/'.$filename.'.blade.php');
/* Create file only if it doesn't exist */
if (!file_exists($filepath)) {
file_put_contents($filepath, $view);
}
/* Add storage/framework/views as a location from where view files can be picked, used in make function below */
view()->addLocation($file_location);
/* call the usual view helper to render the blade file created above */
return view($filename, $data, $mergeData);
}
}
Usage is exactly same as laravel's view() helper, only that now first parameter is the blade string
$view_string = '#if(strlen($name_html)>6)
<strong>{{ $name_html }}</strong>
#else
{{$name_html}}
#endif';
return inline_view($view_string)->with('name_html', $user->name);
return inline_view($view_string, ['name_html' => $user->name]);

I'm getting the above error displaying within my content areas on my Joomla site all a sudden, any suggestions?
Update: No such luck finding access to defined file and directory within godaddy ftp file directory, ftp, or Joomal C-panel.
Within FTP, I cannot find access to this particular file to investigate what is on line 100.
Within the Joomla panel, in Global Configurations, I was able to toggle 'error message' to none for atleast this error to be hidden. Within the cache directory I do not see any options to get into the folder, though it displays.
I also see this at the bottom of that c-panel screen, but just links to a joomla help site, and within the fields I do not see described area to toggle 'ON or OFF'
"Following PHP Server Settings are not optimal for Security and it is recommended to change them:

It is not exactly an error. It is a warning.
Suddenly? Perhaps you have upgraded/updated your PHP version. Or changed PHP configuration to "strict mode".
The message "expected to be a reference, value given" means the called function expected to receive a reference, not a value. Look:
$something = 9;
show_section($something);
// here you are passing a variable
// this will be accepted as a reference
show_section(9);
// here you are NOT passing a reference
// here you are passing a VALUE
When you pass "by reference", the function can change the variable value... in the example above:
function show_section(&$parameter) {
$parameter = 'changed!';
}
Note the ampersand symbol & before the $parameter - this is how we specify a function requires a REFERENCE.
AFTER the function call, in the example above, the variable $something value will be the changed! string.
The line throwing the error is NOT the "global" one. It is the next:
$result = call_user_func_array(array($$object_123456789, $method), $arguments);
The problem here is that the function is being called indirectly by using the "call_user_func_array" function.
A solution would be transforming all arguments into references. Suggestion:
foreach ($arguments as $count => $value)
{
$param = 'param' . $count;
$$param = $value;
$arguments[$count] = &$$param;
}
Put the code above in the beginning of the call function, right after the following line:
$id = serialize($arguments);
Give this a try!
I had made a personal note software in PHP so I can store and organize my notes and wished for a nice simple format to write them in.
I had done it in Markdown but found it was a little confusing and there was no simple syntax highlighting, so I did bbcode before and wished to implement that.
Now for GeSHi which I really wish to implement (the syntax highlighter), it requires the most simple code like this:
$geshi = new GeSHi($sourcecode, $language);
$geshi->parse_code();
Now this is the easy part , but what I wish to do is allow my bbcode to call it.
My current regular expression to match a made up [syntax=cpp][/syntax] bbcode is the following:
preg_replace('#\[syntax=(.*?)\](.*?)\[/syntax\]#si' , 'geshi(\\2,\\1)????', text);
You will notice I capture the language and the content, how on earth would I connect it to the GeSHi code?
preg_replace seems to just be able to replace it with a string not an 'expression', I am not sure how to use those two lines of code for GeSHi up there with the captured data..
I really am excited about this project and wish to overcome this.
I wrote this class a while back, the reason for the class was to allow easy customization / parsing. Maybe a little overkill, but works well and I needed it overkill for my application. The usage is pretty simple:
$geshiH = new Geshi_Helper();
$text = $geshiH->geshi($text); // this assumes that the text should be parsed (ie inline syntaxes)
---- OR ----
$geshiH = new Geshi_Helper();
$text = $geshiH->geshi($text, $lang); // assumes that you have the language, good for a snippets deal
I had to do some chopping from other custom items I had, but pending no syntax errors from the chopping it should work. Feel free to use it.

It looks to me like you already got the regex right. Your problem lies in the invocation, so I suggest making a wrapper function:
function geshi($src, $l) {
$geshi = new GeSHi($sourcecode, $language);
$geshi->parse_code();
return $geshi->how_do_I_get_the_results();
}
Now this would normally suffice, but the source code is likely to contain single or dobule quotes itself. Therefore you cannot write preg_replace(".../e", "geshi('$2','$1')", ...) as you would need. (Note that '$1' and '$2' need quotes because preg_replace just substitutes the $1,$2 placeholders, but this needs to be valid php inline code).
That's why you need to use preg_replace_callback to avoid escaping issues in the /e exec replacement code.
So for example:
preg_replace_callback('#\[syntax=(.*?)\](.*?)\[/syntax\]#si' , 'geshi_replace', $text);
And I'd make a second wrapper, but you can combine it with the original code:
function geshi_replace($uu) {
return geshi($uu[2], $uu[1]);
}
Use preg_match:
$match = preg_match('#\[syntax=(.*?)\](.*?)\[/syntax\]#si', $text);
$geshi = new GeSHi($match[2], $match[1]);
I've got this code, but I'm not sure I make it work:

I'm not sure how to activate it is what I'm trying to say. I placed it in the controller and it's within a function for one of my pages. I don't have any syntax errors. I just don't know how to wake it up and make it work. I thought I could just put youtube_data_grabber('http://www.youtube.com/watch?v=LAcrFym10ZI', 'url'); but that didn't work.
I got the code from this blog, and I have the zend functionality working. I tested it earlier and had no errors. I'm just having trouble with this youtube part.
Any ideas?
That code should go in a helper or plugin not in the controller. The first part of the code on that page should be in your controller. The one you pasted is just an alternate version.
Save your code to application/helpers/youtube_helper.php, then in your controller go ahead and call $this->load->helper('youtube').
Only then will your youtube_data_grabber() function be available.
