無法在codeigniter中插入數據

我是Codeigniter中的新手。我無法將數據插入到我的表格中。我也使用過引導文件。無法在codeigniter中插入數據

這些是查看線路 - groups.php

<input type="text" name="group" id="group" placeholder="Group"> 
<button type="button" name="addgroup" class="btn btn-primary" id="add" data-dismiss="modal">Add</button>

型號 - groups_model.php

function insert_groups($dbdata) { 
     $this->db->insert('groups', $dbdata); 
    }

控制器 - groups_controller.php

public function group() 
    { 
     $this->load->view('groups'); 
     $this->load->model('groups_model'); 
     if(isset($_POST['addgroup'])) 
     { 
      $userID= '2'; 
      $groupname= $this->input->post('group'); 
      //$this->load->model('groups_model'); 
      $data=array(
       'userID'=>$userID, 
       'groupname'=>$groupname 
      ); 
      $this->groups_model->insert_groups($data); 
      //var_dump($this->db->last_query()); 
     } 

    } 
}

我的全HTML表格粘貼下面。那裏有很多評論。

last_query（）是什麼？你檢查查詢嗎？ –

當前我的查看頁面不顯示。這是說沒有找到項目名稱/組。在路由中，我通過$ route ['groups'] = groups_controller/group指定了它。 – upjc

將根改爲'$ route ['groups'] = groups/group' –

爲什麼在應該提交時使用按鈕。

改變這種

<button type="button" name="addgroup" class="btn btn-primary" id="add" data-dismiss="modal">Add</button>

到

<button type="submit" name="addgroup" class="btn btn-primary" id="add" data-dismiss="modal">Add</button>

你必須提交數據，以得到它後

更改了它，但沒有發生插入。 – upjc

你有表單標籤或form_open標籤嗎？ –

我有表格標籤。我在問題末尾附上了完整的groups.php（查看文件）。 – upjc

嘗試

public function group() 
    { 

     $this->load->model('groups_model'); 
     if($this->input->post('addgroup')) 
     { 
      $userID= '2'; 
      $groupname= $this->input->post('group'); 

      $data=array(
       'userID'=>$userID, 
       'groupname'=>$groupname 
      ); 
      $this->groups_model->insert_groups($data); 
        } 
$this->load->view('groups'); 
    } 
}

並添加動作到您的形式：
變化

<form method="post" name="form1">

要

<?= form_open('yourcontroller/action')?> 
//anything HTML inside your form 
<?= form_close()?>

而且你必須加載形式幫助做到這一點。在autoload.php

$autoload['helper'] = array('form');

希望它有幫助！

中提交類似於提交按鈕的類，而不使用form_open並關閉它。不管怎麼說，還是要謝謝你。 – upjc

基本上，你的表單標記中沒有action屬性。

<form method="post" name="form1">

您可以使用此表達式：

<form action="yourcontroller/action" method="post" name="form1">

或使用笨表單輔助

$this->load->helper('form'); 
echo form_open("yourcontroller/action");

希望它可以幫助你。
