Question

我有问题，我无法在数据库中插入标签。我有3个表：制品

id title content date

标签

id name

Tags_in_news

id news_id tag_id

我的HTML：

<form id="form1" name="form1" method="post" action="<?php echo base_url() .'administration/addArticle'; ?>" enctype="multipart/form-data">

p><b>Title:</b></p>
    <input type="text" name="title" id="title" style="width:605px">
<p><b>Tags:</b></p>
  <input type="text" name="dropdiv" id="dropdiv" style="width:605"  /><br />
<p><b>Content:</b></p>
        <textarea name="content" id="content" style="width:605px; height: 300px;" rows="200"></textarea>

        <input type="submit" value="Add" />
</form>

方法：

public function addArticle()
    {
    if ($this->input->post('title', TRUE) and($this->input->post('dropdiv',TRUE)) and strlen($this->input->post('title', TRUE))>3 ) 
    {
        $title     =     addslashes($this->input->post('title'));
        $content   =     addslashes($this->input->post('content'));
        $tags      =     $this->input->post('dropdiv');
        $date      =     date("Y-m-d H:i:s");
        $theid     =     $this->db->insert_id();


        $this->db->query("
                INSERT INTO articles (
                        title, 
                        content,
                        date) 
                VALUES (?, ?, ?)",
                array(
                    $title, 
                    $content, 
                    $date)
            );

        foreach ($tags as $t) 
        {          
            $tag_SQL = $t;
            $this->db->query("insert into tags_in_news (news_id, tag_id) values ('{$theid}','{$tag_SQL}')");
        }
         redirect('administration/add_article', 'redirect');
    }
}

在文章中没有问题数据存储，但在表中tags_in_news不存储，我无法理解问题出在哪里...请帮助
