Laravel 5 中未定义的函数 link_to

Undefined function link_to in Laravel 5

提问by Paul Kitutu

I was trying to create a view in Laravel 5, I used the function link_to to create some html link but to my dismay; I got an error as below:

我试图在 Laravel 5 中创建一个视图，我使用函数 link_to 创建了一些 html 链接，但让我感到沮丧；我收到如下错误：

FatalErrorException Call to undefined function link_to()

FatalErrorException 调用未定义的函数 link_to()

Was this function removed? I know the alternative is to write the actual HTML as <a href='url'>Label</a>but I would prefer to use some function like link_to('url','label');

这个功能去掉了吗？我知道另一种方法是编写实际的 HTML，<a href='url'>Label</a>但我更喜欢使用一些函数，如 link_to('url','label');

link_tois actually illuminate/htmlhelpers which you need to add manually using composer require "illuminate/html=~5.0"or convert to use url()instead.

link_to实际上illuminate/html是您需要手动添加 usingcomposer require "illuminate/html=~5.0"或转换为 use 的助手url()。

There is a method presented in Illuminate\Html\HtmlBuilder.php

Illuminate\Html\HtmlBuilder.php 中有一个方法

/**
 * Generate a HTML link.
 *
 * @param  string  $url
 * @param  string  $title
 * @param  array   $attributes
 * @param  bool    $secure
 * @return string
 */
public function link($url, $title = null, $attributes = array(), $secure = null) { ... }

Instead of using link_to or link_to_*, you can find alternative methods registered in facades. If you set the alias as

除了使用 link_to 或 link_to_*，您还可以找到在 Facades 中注册的替代方法。如果您将别名设置为

'Html'      => 'Illuminate\Html\HtmlFacade'

you can try something like

你可以尝试类似的东西

{!! Html::link('url', 'label') !!}

which will give exactly the same function. Hope this post will be helpful.

这将提供完全相同的功能。希望这篇文章会有所帮助。

There's no link_to function. Use url instead:

没有 link_to 功能。改用 url：

{!! url('path', $task->title) !!}
