Question

我真的不明白为什么这个 @method（'PUT'）在我的SQL中执行未知列'_method'的原因。我将在下面显示所有可能导致此错误的代码。 Laravel版本6.2。

SQLSTATE [42S22]：找不到列：1054中的未知列'_method' 'where子句'（SQL：更新setups设置_method = PUT，id = 1， image = admitad-e1504616712278.png，meta_title =测试， address =测试，contact = testing @ testing，email =测试， social = [“测试”，“测试”]，updated_at = 2019-12-29 15:40:21 _method = PUT）

2019_12_23_171326_create_setups_table.php

public function up()
    {
        Schema::create('setups', function (Blueprint $table) {
            $table->increments('id');
            $table->string('image')->nullable();
            $table->string('meta_title');
            $table->string('address');
            $table->string('contact');
            $table->string('email');
            $table->string('social');
            $table->timestamps();
        });
    }

}

web.php

Route :: resource（'setups'，'SetupController'）;

Answer 1

@method('PUT')

始终打印

<input name="_method" type="hidden" value="PUT">

插入到源html中，如果您不想使用此代码，则可以删除它，或者您想消除它们，在代码中再添加一个值：

$data = Input::except('_token', 'submit','_method');
