Question

我正在尝试使用laravel将循环数据插入数据库，但它返回以下错误：

Grammar.php第118行中的ErrorException：传递给Illuminate \ Database \ Grammar :: parameterize（）的参数1必须是类型数组，给定的字符串，在C：\ xampp \ htdocs \ laravel \ App \ vendor \ laravel \ framework \ src \ Illuminate \ Database \ Query中调用\＃Grammars \ Grammar.php在678行并定义了

查看：

<input name="product_id[]" type="hidden" class="rid" value="13">
<input type="hidden" name="product_name[]" value="Popins"><input type="hidden" name="product_code[]" value="2323">
<input name="unit_price[]" type="hidden" value="170">
<input name="quantity[]" type="text" value="2" id="" >

控制器

for($i=0; $i<count($product_name);$i++){
    $newSafety = new saleItems;
    $newSafety->product_id = $request->unit_price;
    $newSafety->sale_id   = $request->unit_price;
    $newSafety->product_code   = $request->product_code;
    $newSafety->product_name   = $request->product_name;
    $newSafety->quantity   = $request->quantity;
    $newSafety->unit_price   = $request->unit_price;
    $newSafety->gross_total= $request->unit_price;
    $newSafety->save();
}

看起来您传递请求的每个输入都是数组，并且您尝试将它们分配给$ newSafety对象的非数组属性。

试试这个：

for($i=0; $i<count($product_name);$i++){
    $newSafety = new saleItems;
    $newSafety->product_id = $request->unit_price[i];
    $newSafety->sale_id   = $request->unit_price[i];
    $newSafety->product_code   = $request->product_code[i];
    $newSafety->product_name   = $request->product_name[i];
    $newSafety->quantity   = $request->quantity[i];
    $newSafety->unit_price   = $request->unit_price[i];
    $newSafety->gross_total= $request->unit_price[i];
    $newSafety->save();

}
