将多个参数传递给刀片指令 [英] Pass multiple parameters to a blade directive

问题描述

我正在尝试创建一个Blade指令，以突出显示将从搜索查询中返回的某些单词.

I'm trying to create a blade directive to highlight some words that will return from my search query.

这是我的刀片指令:

class AppServiceProvider extends ServiceProvider

{
    public function boot()
    {
        Blade::directive('highlight', function($expression, $string){

            $expressionValues = preg_split('/\s+/', $expression);

            foreach ($expressionValues as $value) {
                $string = str_replace($value, "<b>".$value."</b>", $string);
            }

            return "<?php echo {$string}; ?>";
        });
    }

    public function register()
    {
    }
}

我这样呼叫刀片:

@highlight('ho', 'house')

但是，这个错误跟在我后面

But, this erros is following me:

Missing argument 2 for App\Providers\AppServiceProvider::App\Providers\{closure}()

如何解决?

推荐答案

Blade::directive('custom', function ($expression) {
    eval("\$params = [$expression];");
    list($param1, $param2, $param3) = $params;

    // Great coding stuff here
});

和刀片模板中:

@custom('param1', 'param2', 'param3')
