mailhog我在向新用户发送电子邮件以创建密码时遇到错误。
错误：
Connection could not be established with host mailhog :stream_socket_client(): php_network_getaddresses: getaddrinfo failed: No such host is known.
.env 配置：
MAIL_MAILER=smtp
MAIL_HOST=mailhog
MAIL_PORT=1025

我已经尝试了其他帖子的解释我无法让它工作,因为我总是得到以下警告:警告:get_object_vars()期望参数1是对象,数组给出...
stdclass对象数组如下所示:
Array
(
[0] => stdClass Object
(
[pares] => 4
[moda] => 9
)
[1] => stdClass Object
(
[pares] => 3
[moda] => 8
)
[2] => stdClass Object
(
[pares] => 2
[moda] => 8
)
[3] => stdClass Object
(
[pares] => 5
[moda] => 4
)
[4] => stdClass Object
(
[pares] => 1
[moda] => 1
)
[5] => stdClass Object
(
[pares] => 6
[moda] => 1
)
)
我尝试分别访问值 - modas和pares及其数字 …
我的问题是，鉴于我有以下 php 代码来比较两个字符串：
$cadena1='JUAN LÓPEZ YÁÑEZ';
$cadena2='JUAN LOPEZ YÁÑEZ';
if($cadena1===$cadena2){
echo '<p style="color: green;">The strings match!</p>';
}else{
echo '<p style="color: red;">The strings do not match. Accent sensitive?</p>';
}
我注意到，例如，如果我比较LOPEZ和LÓPEZ，则比较结果为假。
无论西班牙口音如何，是否有一种方法或功能可以比较这些字符串？
如文档中所述，您可以在自定义路径中创建组件，该路径与默认路径views/livewire/和Http/Livewire. 只是为了更好的组织，我创建了子文件夹：
$ php artisan make:livewire tutorial/counter
所以我在以下路径中获取了我的文件：
views/livewire/tutorial/counter.blade.phpHttp/Livewire/Tutorial/Counter.php为了在视图中测试组件，我创建了一个/livewire/tutorial/welcome.blade.php具有以下内容的组件：
<!DOCTYPE html>

Order
- hasMany(CartItem)
- hasManyThrough(Product, CartItem)
CartItem
- belongsTo(Order)
- hasOne(Product)
Product

通过调用动态属性和方法表单(例如$order->products,$order->products()对于Order模型),验证所有关系都在工作
现在我想删除与特定订单相关的所有产品,所以我尝试了这个(订单ID = 3):
Order::find(3)->products()->delete()
但这不起作用.由于某种原因,我收到错误消息,指出无法找到加入列:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'cart_items.order_id' in 'where clause' (SQL: delete from `products` where `cart_items`.`order_id` = 3)

谁知道这里有什么问题？
我最初有一个大数组，我从数据库中得到了一个简短的版本：
$arreglo =Array
(
"0" => Array
(
"concurso" => 2600,
"R1" => 1
),
"1" => Array
(
"concurso" => 2602,
"R1" => 1
),
"2" => Array
(
"concurso" => 2603,
"R1" => 1
),
"3" => Array
(
"concurso" => 2648,
"R1" => 1
),
"4" => Array
(
"concurso" => 2653,
"R1" => 1
),
"5" => Array
(
"concurso" => 2655,
"R1" => 1
),
"6" => Array
(
"concurso" => 2698,
"R1" => 1 …我正在使用Slim Framework和Twig.
我想通过使用部分来应用DRY.我有一个表单,可以在几个视图中重复使用不同的变量,如标题和路由(url)名称.
我正在努力如何使其在URL名称上工作.
例如,在视图中使用带有参数的'urlFor'帮助器的链接如下:
<a href="{{urlFor('route.name', {parameter: value})}}">The link</a>
这就是我想传递给部分模板的链接,因为它在每个视图中都不同,我想使用部分表单.我尝试了几种方法,但它不起作用.我不知道如何传递包含'内部的字符串.
例如,我在父视图中尝试了这样的部分调用,如下所示:
{% include 'partials/partial.php' with {'theUrl': "urlFor('route.name', {parameter: value})"} %}
在里面的部分像这样:
<a href="{{theUrl}}">Show more</a>
它不起作用,因为在浏览器的URL中我看到以下内容:
http://myproject.dev/pages/urlFor('route.name',%20%7Bparameter:%201%7D)
看起来它没有正确转义.有什么想法如何通过路由名称来解决这个问题urlFor()？
我一直在努力研究如何从Eloquent中的集合中获取不同值的数量.
我一直在尝试几种方法,比如在docs上找到的unique(),values()等.即使确实存在count()方法,也没有方法来获取不同值的计数.
例如,通过应用以下查询
$technicalshighestdegrees = Capsule::table('academicinfo AS fa')
->selectRaw('DISTINCT fa.academic_id AS Id,c.name AS Degree')
->leftJoin('academics AS a','fa.academic_id','=','a.id')
->leftJoin('cat_degree AS c','fa.level','=','c.id')
->whereIn('a.type',['Technical'])
->where('a.status','!=','Retired')
->where('c.degree',true)
->orderBy('a.id')
->orderBy('c.hierarchy','desc')/*http://stackoverflow.com/a/17006377/1883256*/
->get();
我收到这个系列:
Illuminate\Support\Collection Object
(
[items:protected] => Array
(
[0] => stdClass Object
(
[Id] => 3
[Grado] => Master
)
[1] => stdClass Object
(
[Id] => 3
[Grado] => Bachelor
)
[2] => stdClass Object
(
[Id] => 4
[Grado] => Master
)
[3] => stdClass Object
(
[Id] => 4 …我有一个数据库中的这个集合,我有一个名为"event_date"的列.
我想要的只是获取集合中该列的日期名称.
我知道你可以使用Carbon来获取名称的日期,例如,一个名为的方法->format(),但是我得到一个错误,说这个方法不存在.
我的代码到目前为止如下:
$collection = MyModel::all();
里面有"event_date"属性或列.从那以后,我想得到将它们放入数组或集合中的日期名称,并最终计算那些天数.
为了实现这一点,我尝试了以下方法:
我尝试了->pluck()如下方法:
$filtered = collect([
'myDates'=>$collection->pluck('event_date'),
]);
而dd($filtered)看起来像如下:
Collection {#209 ?
#items: array:1 [?
"myDates" => Collection {#243 ?
#items: array:30 [?
0 => Carbon {#244 ?
+"date": "2017-02-05 00:00:00.000000"
+"timezone_type": 3
+"timezone": "America/Mexico_City"
}
1 => Carbon {#218 ?
+"date": "2017-01-15 00:00:00.000000"
+"timezone_type": 3
+"timezone": "America/Mexico_City"
}
2 => Carbon {#250 ?
+"date": "2016-09-25 00:00:00.000000"
+"timezone_type": 3
+"timezone": "America/Mexico_City"
}
3 => Carbon {#249 ? …我在Jetstream中创建了一个Livewire组件，并将其设置为web.php路由页面中的全页组件，如下所示：
use App\Http\Livewire\PostComponent;
...
Route::get('posts/',PostComponent::class)->name('posts');
该post-component.blade.php文件最初有以下代码：
<div>
<h1>If you look to others for fulfillment, you will never truly be fulfilled.</h1>
</div>
如果我点击 URL，.../posts我会收到以下错误：
未定义的变量：标题（查看：/home/vagrant/laravelapp/resources/views/layouts/app.blade.php）
所以我尝试在文件中添加插槽post-component.blade.php：
<x-app-layout>
<x-slot name="header">
<h2 class="font-semibold text-xl text-gray-800 leading-tight">
{{ __('Dashboard') }}
</h2>
</x-slot>
<div>
<h1>If you look to others for fulfillment, you will never truly be fulfilled.</h1>
</div>
</x-app-layout>
尽管如此，我还是遇到了同样的错误。
我缺少什么？我该如何解决？
