preg_match()期望参数2为字符串，给定错误的数组 [英] preg_match() expects parameter 2 to be string, array given Error

问题描述

我正在尝试插入数组，但出现错误:-

I'm trying to insert array but I'm getting error:-

preg_match()期望参数2为字符串，给定数组

preg_match() expects parameter 2 to be string, array given

我的下方表单如下:

{!! Form::text('description[]',null,['class' => 'input-field input-sm','v-model'=>'row.description']) !!}
{!! Form::text('log_time[]',null,['class' => 'input-field input-sm','v-model'=>'row.log_time']) !!}

我的控制器存储功能:

$this->validate($request, $this->rules);
        $data = array();
        foreach($request->description as $key=>$value){
            $data[]=[
                'description'=> $value, 
        'log_time'=> $request->log_time[$key], 
        'call_id'=>$call->id,
            ];
        }
       PortLog::create($data);

当我检查 dd($ data)

array:2 [▼
  0 => array:3 [▼
    "description" => "des"
    "log_time" => ""
    "call_id" => 16
  ]
  1 => array:3 [▼
    "description" => ""
    "log_time" => "hi"
    "call_id" => 16
  ]
]

这里我做错了什么?

推荐答案

似乎您正在尝试在一个语句中插入多个port_logs.但是，create()方法仅用于创建模型的一个实例.您要么需要使用insert()语句，要么通过您的$data将代码更新为foreach并发出多个create()语句.

It looks like you're attempting to insert multiple port_logs in one statement. However, the create() method is only meant to create one instance of a model. You either need to use the insert() statement, or update your code to foreach through your $data and issue multiple create() statements.

PortLog::insert($data);

// or

foreach($data as $row) {
    PortLog::create($row);
}

如果您只想插入数据，而又不想实例化一堆PortLog实例，那么insert()方法是您的理想选择.如果您需要为每一行实例化一个新的PortLog实例，那么create()方法就是您的理想选择.

If you just want to insert the data, and you don't want to instante a bunch of PortLog instances, then the insert() method is the way to go. If you need to instantiate a new PortLog instance for each row, then the create() method is the way to go.
