Question

我正在尝试将数组作为一行插入到我的数据库中的“费用”表中：

public function insert_expense($expenses){
    $this->db->insert_batch('expenses', $expenses); 
}

我一直收到这个错误：

发生数据库错误
  错误号码：1364
  字段'exp_user'没有默认值
  INSERT INTO expenses（）VALUES（），（），（），（），（），（），（），（），（），（），（），（）
  文件名：models / Expenses_model.php
  行号：26

这是我桌子的结构：

这是我试图插入的一个例子：

array(12) {
    ["exp_user"] "1"
    ["exp_date"] "2016-10-18"
    ["exp_date_request"] "2016-10-18"
    ["exp_client"] "Potato"
    ["exp_provider"] "Miew"
    ["exp_amount"] "1"
    ["exp_currency"] "₪"
    ["exp_budget"] "budget2"
    ["exp_method"] "cc"
    ["exp_frequency"] "Monthly"
    ["exp_expenditure"] "asdasdas asdas dsa as"
    ["exp_charge_client"] NULL
}

如果变量$expenses是您示例中的数组：

$expenses = array(
    "exp_user" => "1",
    "exp_date" => "2016-10-18",
    "exp_date_request" => "2016-10-18",
    "exp_client" => "Potato",
    "exp_provider" => "Miew",
    "exp_amount" => "1",
    "exp_currency" => "₪",
    "exp_budget" => "budget2",
    "exp_method" => "cc",
    "exp_frequency" => "Monthly",
    "exp_expenditure" => "asdasdas asdas dsa as",
    "exp_charge_client" => NULL
);

您无法在insert_batch函数中使用它（因为insert_batch函数需要获取一组数组（数据）作为第二个参数）。

基本上insert_batch函数可以插入多行（不需要循环insert函数）。您可以使用多维数组：

$expenses = array(
    array(
        "exp_user" => "1",
        "exp_date" => "2016-10-18",
        "exp_date_request" => "2016-10-18",
        "exp_client" => "Potato",
        "exp_provider" => "Miew",
        "exp_amount" => "1",
        "exp_currency" => "₪",
        "exp_budget" => "budget2",
        "exp_method" => "cc",
        "exp_frequency" => "Monthly",
        "exp_expenditure" => "asdasdas asdas dsa as",
        "exp_charge_client" => NULL
    ),
    array(
        "exp_user" => "1",
        "exp_date" => "2016-10-18",
        "exp_date_request" => "2016-10-18",
        "exp_client" => "Potato",
        "exp_provider" => "Miew",
        "exp_amount" => "1",
        "exp_currency" => "₪",
        "exp_budget" => "budget2",
        "exp_method" => "cc",
        "exp_frequency" => "Monthly",
        "exp_expenditure" => "asdasdas asdas dsa as",
        "exp_charge_client" => NULL
    ),
    array(
        "exp_user" => "1",
        "exp_date" => "2016-10-18",
        "exp_date_request" => "2016-10-18",
        "exp_client" => "Potato",
        "exp_provider" => "Miew",
        "exp_amount" => "1",
        "exp_currency" => "₪",
        "exp_budget" => "budget2",
        "exp_method" => "cc",
        "exp_frequency" => "Monthly",
        "exp_expenditure" => "asdasdas asdas dsa as",
        "exp_charge_client" => NULL
    )
);

现在使用insert_batch。

是有道理的

如果您只想插入1条记录，可以使用insert功能：

$this->db->insert('expenses', $expenses);

或将通话更改为：

$this->db->insert_batch('expenses', array( $expenses ) );

CodeIgniter insert_batch：字段'exp_user'没有默认值
