}else{
$data=array(
'email'=>$this->input->post('email'));
$this->blog_m->registre($data);
echo "<div class='alert'>Inscription success</div>";
echo "email";
}
}
}There is no error but the data does not insert in the database and there is no success message.
没有错误但是数据没有插入到数据库中，也没有成功信息。

Try this.
尝试这个。
In View (AJAX Part)
在视图中（AJAX 部分）
<script>
$(function(){
$( "#btn" ).click(function(event)
{
event.preventDefault();
var email= $("#email").val();
$.ajax(
{
type:"post",
url: "<?php echo base_url(); ?>index.php/blog_c/registre",
data:{ email:email},
success:function(response)
{
console.log(response);
$("#message").html(response);
$('#cartmessage').show();
}
error: function()
{
alert("Invalide!");
}
}
);
});
});
</script>
In Controller
在控制器中
public function registre()
{
$email = $this->input->post('email'); # add this
$this->form_validation->set_rules('email','EMAIL','trim|required|valid_email|is_unique[utilisateurs.email]');
if($this->form_validation->run() == FALSE)
{
echo validation_errors();
}
else
{
if(!$this->blog_m->registre($email))
{
echo "Something Went Wrong";
}
else
{
echo "Inscription success";
}
}
}
In Model
在模型中
function registre($email)
{
$data = array(
'email'=>$this->input->post('email')
);
$this->db->insert('utilisateurs',$data);
}
回答by Hikmat Sijapati
In your controller load model first.Like this..
首先在您的控制器加载模型中。像这样..
public function __construct()
{
parent::__construct();
$this->load->helper(array('form','url'));//loads required heplers
$this->load->model('blog_m');//loads your model
}
In view: you are using ajax so set form actionempty.Like this..
鉴于：您正在使用ajax，因此将表单设置为action空。像这样..
<?php echo form_open('',array('id'=>'myForm'));?>
