【问题描述】:
我想在选择选项标签中显示一个选定的值,带有特定的 id, 我有一个帖子表
+---------+-------------+---------------+-------------+
| post_id | post_title | post_content | category_id |
+---------+-------------+---------------+-------------+
| 1 | Title One | Content One | 1 |
+---------+-------------+---------------+-------------+
| 2 | TitleTwo | Content Two | 1 |
+---------+-------------+---------------+-------------+
| 3 | Title Three | Content Three | 2 |
+---------+-------------+---------------+-------------+
然后我有一个类别表
+-------------+----------------+
| category_id | category |
+-------------+----------------+
| 1 | Category One |
+-------------+----------------+
| 2 | Category Two |
+-------------+----------------+
| 3 | Category Three |
+-------------+----------------+
我用选择选项标签显示类别
控制器添加
function add(){
if ($this->input->post('submit'){
$data = array(
'post_title' => $this->input->post('post_title'),
'post_content' => $this->input->post('post_content'),
'category_id' => $this->input->post('category_id'));
$this->db->insert('post_table',$data);
}
$data[cats] = $this->db->get(category_table)->result();
$this->load->view('view_add_post');
}
查看添加,
<form method="post" action="<?php echo base_url();?>index.php/post/add">
<input type="text" name="post_title">
<textarea name="post_content"></textare>
<select name="category_id">
<?php foreach ($cats as $category) { ?>
<option value="<?php echo $category->category_id ?>"><?php echo $category->category?>
<?php } ?>
</select>
<input type="submit" name="submit" value="Save">
</form>
控制器编辑
function edit($id){
$data['post'] = $this->db->get_where('post_table' array('post_id',$id))->row();
$data['cats'] = $this->db->get('category_table)->result();
$this->load->view('view_edit_post',$data)
}
编辑视图
这是我想在下拉选择选项中显示类别的问题,其中选择的是我输入的第一个,例如我已经输入了类别 id 为 1 的帖子,然后当我在选择选项中编辑类别 1 时自动选中,怎么做?
<select name="category_id">
<?php foreach ($cats as $category) { ?>
<option value="<?php echo $category->category_id ?>"><?php echo $category->category?>
<?php } ?>
</select>
// the selected option is automatically
对不起,我的英语不好。
