因为我有保存和更新按钮,所以我需要知道在laravel上的请求表单中单击了哪个按钮.
App\Http\Requests\RegistrationRequest.php
public function rules()
{
$myrule = [ 'name' => 'required', 'age' => 'required' ];
if (isset($_POST['save']))
{
$myrule['application_form'] = 'required';
}
elseif (isset($_POST['update']))
{
$myrule['application_form'] = 'required_without:is_application_form';
}
return $myrule;
}
我需要知道单击的按钮是Save还是Update,因为如果单击Save按钮我需要application_form文件字段,但是如果is_application_form hidden字段为空,我只需要application_form字段.
上面的设置适用于名称和年龄字段,但忽略IF条件内的代码.
我有一个使用此迁移代码创建的现有表：
Schema::create('mytable', function (Blueprint $table) {
$table->increments('id');
$table->double('mycolumn',8,2)->unsigned()->default(0);
$table->timestamps();
});
然后我创建了另一个迁移文件，mycolumn用下面的迁移文件来调整我的字段的值范围。
Schema::table('mytable', function (Blueprint $table) {
$table->double('mycolumn',15,2)->unsigned()->default(0)->change();
});
但是我收到一个错误：
In DBALException.php line 283:

array:2 [?
0 => array:3 [?
"time" => 7780
"name" => "John A. Doe"
"photo" => "johndoe.png"
]
1 => array:3 [?
"time" => 49800
"name" => "Jane B. Doe"
"photo" => "janedoe.png"
]
]
该time值是秒，我的问题是如何循环遍历数组，以便可以运行以下函数：
"time" => $this->secondsToHumanReadable(49800)
我的函数secondsToHumanReadable已经过测试并且可以正常工作，我只希望它插入time数组结果中的值。
更新：
所需的输出将是：
array:2 [?
0 => array:3 [?
"time" => '2 days, 1 hour, 3 minutes, 45 seconds'
"name" => "John A. Doe"
"photo" => "johndoe.png"

1 => array:3 [?
"time" => …
