Laravel 5.5从带有参数的刀片视图中调用Controller函数 [英] Laravel 5.5 call Controller function from blade view with parameter

问题描述

我有一个产品滑块，我正在尝试找到每种产品的最低价格.

I have a slider of products and i'm trying to find the lowest price of each product.

因此，我首先要尝试从Controller成功调用函数并传递产品的id并打印出来.

So i'm trying, first of all, to successfully call a function from a Controller and pass the id of the product and also print it out.

blade.php

 <span class="text-bold">
   @php
    use App\Http\Controllers\ServiceProvider;
    echo ServiceProvider::getLowestPrice($product_cat->id);
   @endphp
 </span>

路线

Route::post('/getLowestPrice/{id}', 'ServiceProvider@getLowestPrice');

控制器

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class ServiceProvider extends Controller
{
    public static function getLowestPrice($id) {
        return $id;
    }
}

我得到一个错误

Parse error: syntax error, unexpected 'use' (T_USE) 

您知道为什么use在这里不起作用吗?

Any idea why use is not working here?

推荐答案

您不能在方法内使用use关键字

you can't use use keyword inside method

您可以像这样编写完整的类路径

you can write the full class path , like this

 <span class="text-bold">
   @php
    echo App\Http\Controllers\ServiceProvider::getLowestPrice($product_cat->id);
   @endphp
 </span>
