foreach 数组插入到数据库
foreach array insert to database
我有 3 张桌子。类别、成分和 category_ingredient。现在我想将类别和成分的 ID 插入到 category_ingredient。但我收到这样的错误:
这是我的代码:

您将 $ingredient_id
视为字符串,但它是一个数组。我通常用我期望的类型命名我的变量,这样我就不会混淆......例如,$ingredient_id_array
.
// var_dump($saveData); die();
$ingredient_id_array = $this->products_model->saveIngredients($saveData);
foreach (explode(',', $this->input->post('ingredient_category')) as $key => $value)

foreach ( $ingredient_id_array as $key => $str ){
$joinData[] = array(
'ingredient_id' => intval( $str ),
'category_id' => intval( trim($value) )
