调研方向

首先检查负责注入返回视图函数的 Volt 渲染器,然后使用此报告中的三个组件代码片段重现该问题。跟踪规则、渲染文本和变量名中的单词 "new" 如何改变生成的 PHP;当这些示例能够在没有格式错误的 PHP 或异常的情况下完成渲染时,即表示完成。

Description

As soon as the word "new" appears in certain places of the volt component, the rendering gets weird.

I show 3 examples, but I had even more issues. I guess they all point to the same problem.

I upgraded from Livewire 3 to 4 and I do have numerous Volt components in my project. Quite a few are affected by this bug.

Steps To Reproduce
1. Example
  rules([
     'count' => ['required', 'int', 'min:1', 'max:1000', new \App\Rules\GhpRule],
     'gift' => ['boolean'],
  ]);

becomes by the volt renderer

  rules([
     'count' => ['required', 'int', 'min:1', 'max:1000', return new \App\Rules\GhpRule],
     'gift' => ['boolean'],
  ]);

Which gives an exception.

2. Example

THIS DOES cause a render problem:

<?php

use function Livewire\Volt\{state,on,computed};

state([
   'new_count' => false,
]);

?>

<div x-data>
   <x-svg-icon title="{{ 'Previous new contribution' }}" class="{{ $new_count ? '' : 'opacity-30' }}" icon="up"/>
</div>


THIS DOES NOT cause the render problem:

<?php

use function Livewire\Volt\{state,on,computed};

state([
'new_count' => false,
]);

?>

<div x-data>
<x-svg-icon title="{{ 'Previous contribution' }}" class="{{ $new_count ? '' : 'opacity-30' }}" icon="up"/>
</div>

All that I had to change was to change Previous new contribution to Previous contribution !

The render problem is that the return view function is injected inside the last php function found in the volt component. Which causes an exception at the protected keyword.

3. Example

$new = computed(fn() => $this->forumThread);
becomes by the volt renderer

return new = computed(fn() => $this->forumThread);
Which then throws an exception or course.

When I change this to:

$newThread = computed(fn() => $this->forumThread);
everything works.
