插入具有相同文本字段值的多个复选框值(codeigniter)

标签: php codeigniter checkbox

我试图将值放入MySQL表中,如下所示:

| --- --- sbjct_name | --- ---水平|

| ----------物理---------- | ---- Level 1 ----- |

| ----------物理---------- | ---- Level 2 ----- |

| ----------物理---------- | ---- Level 3 ----- |

| ----------微积分--------- | ----第1级----- |

| ----------微积分--------- | ---- Level 2 ----- |

(我不知道怎么做桌子,但我想你明白了)

我要说我要把数学"数学"进入sbjct_name列和" Level 1"," Level 2"," Level 3"值进入级别列。

基本想法来自this pict (selecting value for a same input text value)

而不是插入"数学"每个级别多次, 我试图用复选框标记一次提交它。它将类似于this pict (with checkbox)

我不知道如何实现这一目标(或者如果CI可能的话)。

这是我的控制器中的一些代码,

public function add_subject()
{
    $data = array();

    if ($this->input->post('savebttn'))
    {
        $this->form_validation->set_rules('sbjct_name', 'Subject Name', 'trim|required|xss_clean');
        $this->form_validation->set_rules('level', 'Level', '|required|is_natural');
        $this->form_validation->set_error_delimiters('<span class="fielderror">','</span>');

        if ($this->form_validation->run() == FALSE)
        {
            $data['reset'] = FALSE;
        }
        else
        {
           //I don't know what to do here
           //I don't know what to do here
           //I don't know what to do here
           //I don't know what to do here
        }
    }
    $data['level'] = $this->admin_model->get_checkbox_option('level', 'lvl_id', 'lvl_name');
    $data['page'] = 'createsubject';
    $this->load->view('admin/main', $data);
}

这是模型中的复选框视图功能

public function get_checkbox_option($table, $id, $name, $selected=0)
{
    $query = $this->db->get($table);
    $select= '';
    if ($query->num_rows() > 0)
    {
        foreach ($query->result_array() as $row)
        {
            $selected_option = ($selected == $row[$id]) ? 'selected = "selected" ':' ';
            $select .='<input type="checkbox" name="level" value="'.$row[$id].'" '.$selected_option.'>'.$row[$name].'<br>';
        }
    }
    return $select;
}

这是视图上的表单,

    <form action="" method="post" id="createcategoryform">
        <table>
            <tbody>
                <tr>
                    <td><div class="label">Subject Name</div></td>
                    <td><div class="input">
                        <input type="text" name="sbjct_name" size="39" class="ui-corner-all input-text validate[required]">
                        <?=form_error('sbjct_name');?>
                    </div></td>
                </tr>
                <tr>
                    <td><div class="label">Level</div></td>
                    <td><div class="input-text ui-corner-all validate[required]">
                        <?=(isset($level)) ? $level: '';?>
                    </div><?=form_error('level');?></td>
                </tr>
                <tr>
                    <td>&nbsp;</td>
                    <td><input type="submit" value="Save" name="savebttn" class="input-button ui-corner-all ui-state-default"></td>
                </tr>
            </tbody>
        </table>
    </form>

如果你能给出任何线索,我将不胜感激。 :d

<强>第一

将您的复选框设为数组,使其看起来像这样

$select .='<input type="checkbox" name="level[]" value="'.$row[$id].'" '.$selected_option.'>'.$row[$name].'<br>';

注意名字。你的name="level"和我的name="level[]" ,那么你可以将所有级别作为一个变量获取

<强>第二

让你的控制器像这样

if ($this->form_validation->run() == FALSE)
        {
            $data['reset'] = FALSE;
        }
        else
        {
          // make array container for input batch
          $insertData = array();
          if(!empty($this->input->post('level'))) {
              foreach($this->input->post('level') as $level) {
                    $tempArray = array(
                      'sbjct_name' => $this->input->post('sbjct_name'),
                      'level' => $level
                    );

                    array_push($insertData, $tempArray);
              }

              // it's better to put this in model
              // but for example purpose I put it there
              $this->db->insert_batch('table', $insertData);

              //do what you want to do here
          }
        }
