如何插入多个复选框值连续排在MySQL笨

Question

employer_rgn.php

<div class="form-group"> 
    <label for="" class="control-label col-xs-2"> 
    <?php echo $this->lang->line('spclzd_ctgry'); ?> 
    </label> 
    <div class=" col-md-8">    
    <input type="checkbox" name="spec_cat[]" value="Information Technology"> Information Technology 
    <input type="checkbox" name="spec_cat[]" value="Engineering/Manufacturing">Engineering/Manufacturing <br /> 
    <input type="checkbox" name="spec_cat[]" value="Banking & Financial Services"> Banking & Financial Services 
    <input type="checkbox" name="spec_cat[]" value="BPO/ITES"> BPO/ITES <br /> 
    <input type="checkbox" name="spec_cat[]" value="FMCG/Retail"> FMCG/Retail 
    <input type="checkbox" name="spec_cat[]" value="Telecom/ISP"> Telecom/ISP <br /> 
    <input type="checkbox" name="spec_cat[]" value="Pharmaceuticals/Health Care"> Pharmaceuticals/Health Care 
    <input type="checkbox" name="spec_cat[]" value="Sales & Marketing"> Sales & Marketing <br /> 
    <input type="checkbox" name="spec_cat[]" value="Other Non IT"> Other Non IT 
    </div> 
</div> 

employer_model

public function insert() 
{ 
    //Insert second stage details for employer into database. 
    $Specilized_category = $this->input->post('spec_cat'); 
    $data=array('Specilized_category'=>implode(",", $Specilized_category),); 
    $this->db->insert('tbl_employer', $data); 

我将复选框值成用逗号分隔的数据库。但问题是，我需要从数据库中取回选中的值以编辑我的代码。我如何使用implode方法得到这些值？或者是否必须更改我的代码以将值插入数据库？

当你implode它创建一个数组，所以它的类型可以是数组，当它试图插入到MySQL。但在转换为字符串或json字符串后，您可以存储多个值。

像...

public function insert() 
{ 
    //Insert second stage details for employer into database. 
    $Specilized_category = $this->input->post('spec_cat'); 
    $data=array(
    'Specilized_category'=>json_encode(implode(",", $Specilized_category)), 
); 
$this->db->insert('tbl_employer', $data); 

尝试，让我知道如果你遇到任何问题，同时插入.. ['}
