Codeigniter - Save input value in mysql - php

Question

I have an input in my code that update a value in MySQL, but is not working, if i set the value manually in PHPMyAdmin, the value display in HTML, but when i try update, return to 0.
I have the same code to do a similar function, and have copied, and it still isn't working.
Controller:
function ordemmobile(){
$ordemmobile = $this->input->post('ordemmobile');
$id = $this->input->post('id');
if($id > 0){
$data['ordemmobile'] = $ordemmobile;
$data['id'] = $id;
if( $this->categorias_model->alterar($data)){
$ret = "success";
$msg = "Ordem alterada com sucesso!";
}else{
$ret = "danger";
$msg = "Erro ao alterar a ordem :(";
}
}else{
$ret = "danger";
$msg = "Erro ao alterar a ordem :(";
}
echo json_encode(array('status' => $ret , 'msg' => $msg));
}
View:
echo "<td><input type=\"number\" name=\"ordemmobile\" value=\"".$registro->ordemmobile."\" style=\"width:80px; margin:0\" class=\"ordemmobile\" data-id=\"".$registro->id."\" data-url=\"".base_url('adm/'.$this->router->fetch_class().'/ordemmobile')."\" /><span style=\"display:none\">".$registro->ordemmobile."</span></td>";
Model (alterar):
function alterar($data){
$this->db->where('id',$data['id']);
return $this->db->update('ga845_categorias',$data);
}

Looks like it should work if the inputs are getting posted. Checking both inputs would be a good idea.
Consider this
function ordemmobile()
{
$ordemmobile = $this->input->post('ordemmobile');
$id = $this->input->post('id');
if(empty($id) || empty($ordemmobile))
{
$ret = "danger";
$msg = "Erro ao alterar a ordem :(";
}
else
{
$data['ordemmobile'] = $ordemmobile;
$data['id'] = $id;
if($this->categorias_model->alterar($data))
{
$ret = "success";
$msg = "Ordem alterada com sucesso!";
}
else
{
$ret = "danger";
$msg = "Erro ao alterar a ordem :(";
}
}
echo json_encode(array('status' => $ret, 'msg' => $msg));
}
You should also take a good look at what your browser's Web Developer Tools tell you about the request to and response from the server.
