我試圖通過在收件箱中選擇多個複選框,然後點擊提交刪除刪除從我的數據庫中的多個私人信息。我有下面的代碼,但沒有任何反應。我不知道我錯過了什麼..笨刪除多行與複選框
查看:
<?php echo form_open('pm/remove_checked'); ?>
<?php foreach ($query as $row): ?>
<input type="checkbox" name="msg[]" value="<?php echo $row->id; ?>" />
<?php echo $row->from; ?>
<?php echo $row->subject; ?>
<?php echo date("m/d/Y",strtotime($row->msg_date)); ?>
<?php endforeach; ?>
<?php echo form_submit('delete', 'Delete'); ?>
</form>
控制器:
function remove_checked()
{
//validation rules
$this->form_validation->set_rules('msg[]', 'Private Message', 'required|xss_clean');
if ($this->form_validation->run() == FALSE)
{
$data['query'] = $this->Pm_model->received_msg();
$this->load->view('pm/inbox', $data);
}
else //success
{
$checked_messages = $this->input->post('msg'); //selected messages
$this->Pm_model->delete_checked($checked_messages);
//redirect to inbox
}
}
型號:
function delete_checked($checked_messages)
{
$checked_messages = array();
foreach ($checked_messages as $msg_id):
$this->db->select('id');
$this->db->from('user_msg');
$this->db->where('id', $msg_id);
$this->db->limit(1);
$query = $this->db->get();
if ($query->num_rows() > 0) //if message exists
{
$this->db->where('id', $msg_id);
$this->db->where('recipient', $this->users->get_user_id()); //verify if recipient id is equal to logged in user id
$this->db->delete('user_msg');
}
else
{
return FALSE;
}
endforeach;
}
感謝您的建議!我不知道「繼續」和交易。對於循環,我不得不使用'($ checked_messages作爲$ key => $ msg_id)'..我沒有得到數組項的值。 – CyberJunkie
