php - 具有相同名称的多个文本输入 - 添加到数据库

Question

我有一个包含多个字段的表单，所有字段都可以相乘

<input type="text" name="child_name[]" />
<input type="text" name="child_age[]" />
<input type="text" name="child_gender[]" />    
<input type="text" name="child_school[]" />

我想使用 foreach 将多行添加到数据库中的表中，但每次我尝试时都会收到错误提示

"Unknown column 'Array' in 'field list'"

当我打印出数据时，它会将所有字段显示为数组，所以我一定是对 foreach 语句做错了什么，但我不知道是什么

Array ( [child_name] => Array ( [0] => child one [1] => child two) [child_age] => Array ( [0] => 14 [1] => 13 ) [child_gender] => Array ( [0] => male [1] => female ) [child_school] => Array ( [0] => burnside [1] => summer heights high ) )

如有任何帮助，我们将不胜感激!#

这是我的foreach的代码

foreach ($_POST['child_name'] as $child_name)
    {
        $insert_children_data = array(
            'child_name' => $_POST['child_name'],
            'child_age' => $_POST['child_age'],
            'child_gender' => $_POST['child_gender'],
            'child_school' => $_POST['child_school']
        );
        $insert = $this->db->insert('portrait_children', $insert_children_data);
        return $insert;
    }

试试这个(假设您的表单中的每个 child_name、child_age 等都有相同数量的元素):

for ($ix=0; $ix<count($_POST['child_name']); $ix++)
{
    $insert_children_data = array(
        'child_name' => $_POST['child_name'][$ix],
        'child_age' => $_POST['child_age'][$ix],
        'child_gender' => $_POST['child_gender'][$ix],
        'child_school' => $_POST['child_school'][$ix]
    );

    $insert = $this->db->insert('portrait_children', $insert_children_data);
    //return $insert; //you cant return here. must let the loop complete.
}
