Codeigniter update from query within controller
提问by user2505513
Hope I can explain this properly...
希望我能正确解释这个......
I am using form validation with Codeigniter. If my form returns a string id back to the controller, how can I use this to perform a database query and use the result array to perform an update...
我正在使用 Codeigniter 进行表单验证。如果我的表单将字符串 id 返回给控制器,我如何使用它来执行数据库查询并使用结果数组来执行更新...
Does that make sense?
那有意义吗?
function form($id) {
if ($this->form_validation->run('') == false) {
//...
}
else {
// Query database where strId = $this->input->post('strId')
// Put results into an array called $data
// Update database where id = $this->input->post('id')
$this->db->where('id', $this->input->post('id'));
$this->db->update('database', $data);
}
}

Controller:
控制器:
//... (if valid) ...
$this->load->model('myform'); //loads myform_model.php
$this->myform->update(); //call the update method
Model (myform_model.php):
模型(myform_model.php):
function update(){
$this->load->database();
$this->db->where('id', $this->input->post('id'));
$this->db->update('tableName', $data);
}
Note: Your id must already exist in the database table since you're using "update". To insert data, use $this->db->insert();
注意:您的 id 必须已经存在于数据库表中,因为您使用的是“更新”。要插入数据,使用 $this->db->insert();

很好的代码很好:
function update($id, $data) {
函数更新($id,$data){
$this->db->where('id', $this->input->post('$id'));
$this->db->update('tableName', $data);
}
or lik this:
或者像这样:
function update($id, $data) {
函数更新($id,$data){
$this->db->where('id', '$id');
$this->db->update('tableName', $data);
}
