[英]Assign the AUTO_INCREMENT value to another field
Need your help. 需要你的帮助。 I have a table with 3 columns (id, name, filename)
name
and filename
are a string. 我有一个包含3列(ID,名称,文件名)的表,
name
和filename
是一个字符串。 The id
field is AUTO_INCREMENT
so I don't have to post it on array. id
字段是AUTO_INCREMENT
所以我不必将其发布在数组上。 But the problem is on the filename
field which is a combination string of id
and name
with '-' delimiter. 但是问题出在
filename
段上,该字段是id
和name
的组合字符串,并带有'-'分隔符。 My expected results of filename
is 我对
filename
预期结果是
+---+-------+-----------+
|id | Name | Filename |
+---+-------+-----------+
| 1 | James | 1-James |
| 2 | John | 2-John |
| 3 | Clark | 3-Clark |
+---+-------+-----------+
My code is: 我的代码是:
$data = array(
'name' = $this->input->post('name');
'filename' =$this->input->id->post('name');
)
$this->db->insert('dbname', $data)
?>
You need to first insert data. 您需要首先插入数据。 Then get last inserted Id and using this you need to update record
然后获取最后插入的ID,并使用此ID更新记录
$data = array(
'name' => $this->input->post('name');
'filename' => $this->input->id->post('name');
)
$this->db->insert('dbname', $data);
$last_id = $this->db->insert_id();
$new_file_name = $last_id."-".$this->input->post('name');
$update_data = array(
'filename' => $new_file_name;
);
$this->db->where('id',$last_id);
$this->db->update('dbname', $update_data);
