Question

我有一个表，每行有3列：name，enable，disable。启用和禁用列有一个复选框，正如名称所示，我试图每行只勾选一个复选框。到目前为止，这些是我的代码（对于每一行和两列）：

<?php foreach($customers as $customer):?>
<tr>
    <td align="center"><?php echo $customer;?></td>
    <?php
    $check = FALSE;
    if($user_customer != FALSE)
        foreach($user_customer as $object)
            foreach($object as $current_customer)
                if($current_customer == $customer)
                    $check = TRUE;
    ?>

    <td align='center'>
        <?php
            if($check == FALSE)
                $data = array('name' => 'enable[]', 'value' => $customer, 'checked' => FALSE);
            else
                $data = array('name' => 'enable[]', 'value' => $customer,  'checked' => TRUE);

            echo form_checkbox($data);
        ?>
    </td>
    <td align='center'>
        <?php
            if($check == TRUE)
                $data = array('name' => 'disable[]', 'value' => $customer, 'checked' => FALSE);
            else
                $data = array('name' => 'disable[]',  'value' => $customer, 'checked' => TRUE);

            echo form_checkbox($data);
        ?>
    </td>

</tr>
<?php endforeach?>

在我提交表单后，它会相应地将值存储到数据库中，但我不希望用户能够一次勾选两个复选框。我尝试使用单选按钮，但每列只检查一次。我试图按行，任何帮助吗？

P.S。我不想使用任何Javascript。

编辑，我为每一行添加了一个计数器，因此对于第一行等它将是radio_1，这是我编辑的部分：

<td align='center'>
    <?php
        if($check == FALSE)
            $data = array('name' => "radio_$counter", 'value' => $customer, 'checked' => FALSE);
        else
            $data = array('name' => "radio_$counter", 'value' => $customer,  'checked' => TRUE);

        echo form_radio($data);
    ?>
</td>
<td align='center'>
    <?php
        if($check == TRUE)
            $data = array('name' => "radio_$counter", 'value' => $customer, 'checked' => FALSE);
        else
            $data = array('name' => "radio_$counter",  'value' => $customer, 'checked' => TRUE);

        echo form_radio($data);
    ?>
</td>

编辑2，这就是我在控制器功能中检索它的方式：

// These were the arrays that I assigned to each checkbox according to the column
$enable = $this->input->post('enable');
$disable = $this->input->post('disable');

// I used it for inserting and deleting values
$insert = $this->home_model->insert_customer(array('user_id'=>$user_id, 'customer'=>$enable));
$delete = $this->home_model->delete_customer($user_id, $disable);

最终我设法在不使用javascript的情况下解决了我的问题。

首先，在我看来，我在td中使用了一个隐藏输入和一个复选框输入。如下所示，有两种不同的数组。隐藏的输入数组名为disable[]，复选框数组将包含提交表单时所有选中的复选框值，名为enable[]。

隐藏的输入数组disable[]将始终提交值，无论如何。现在我们在disable[]数组中拥有所有客户名称。

查看：

<td align='center'>
    <input type="hidden" value="<?php echo $customer?>" name='disable[]'>
    <?php
        if($check == FALSE)
        {
            $data = array('name' => 'enable[]', 'value' => $customer, 'checked' => FALSE);
        }
        else
            $data = array('name' => 'enable[]', 'value' => $customer,  'checked' => TRUE);

        echo form_checkbox($data);
    ?>
</td>

现在我操作数组以获取我想要的值。就我而言，我的数据库表只有两列user_id和customer。每次用户想要启用或禁用他/她的客户时，我都会添加和删除。这就是我想要获得两个数组的原因。

控制器：

// Array containing selected/checked customers
$enable = $this->input->post('enable');

// Array containing all customers
$disable = $this->input->post('disable');

// Loop through selected customers
foreach($enable as $index => $value)
{
    // Check if customer exists in database
    if( $this->home_model->check_customer($user_id, $enable[$index]) )
    {
        // If exists, unset from enable to prevent duplicate insert
        unset($enable[$index]);
    }

    /* Unset the remaining
    (or all selected customers if it doesn't exists in DB)
    selected customers from disable array */

    $key = array_search($value, $disable);
    unset($disable[$key]);
}

现在在同一个控制器中，只需进行3次简单检查，看看是否确保执行哪个查询，如果有客户要插入和删除，是否只有客户要插入，或者是否只有客户要删除

// Check enable and disable array are not empty
if( ! empty($enable) && ! empty($disable) )
{
    $insert = $this->home_model->insert_customer(array('user_id'=>$user_id, 'customer'=>$enable));
    $delete = $this->home_model->delete_customer($user_id, $disable);
}
// If enable array is not empty but disable is empty, insert only
elseif( ! empty($enable) && empty($disable) )
{
    $insert = $this->home_model->insert_customer(array('user_id'=>$user_id, 'customer'=>$enable));
}
// If enable is empty but disable is not empty, delete only
elseif( empty($enable) && ! empty($disable) )
{
    $delete = $this->home_model->delete_customer($user_id, $disable);
}

仅为每行选中一个复选框
