}Controller :

public function index()

$this->load->view('blog_w');
}
public function registre()
{
// set rules
$this->form_validation->set_rules('email','EMAIL','trim|required|valid_email|is_unique[utilisateurs.email]');
if($this->form_validation->run()==FALSE)
{
echo validation_errors();
}else{
$data=array(
'email'=>$this->input->post('email'));
$this->blog_m->registre($data);
echo "<div class='alert'>Inscription success</div>";
echo "email";
}
}
}没有报错，但是数据没有插入数据库，也没有成功信息。
最佳答案
试试这个。
在 View 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>
在 Controller 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";
}
}
}
在模型中
function registre($email)
{
$data = array(
'email'=>$this->input->post('email')
);
$this->db->insert('utilisateurs',$data);
}
