Is there any way to compile a blade template from

问题:

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')); 
?>

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;
}

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: This package is not compatible with the Laravel 5.7
