I'm new using codeigniter. I'm trying to display items from my database, but I don't know why it doesn't work. Could you help me, please?

My Controller

function Usuario extends CI_Controller{
    function construct(){
    public function modificar_usuario(){
        $id_usuario = 1;
        $data['resultado'] = $this->usuario_m->ver_datos_usuario($id_usuario);


This is my Model:

public function ver_datos_usuario($id_usuario)

    $this->db->select('nombre','apellido','nro_ci', 'direccion','email','telefono','password');
    $this->db->where('id_usuario', $id_usuario);
    $query = $this->db->get();
    return $resultado = $query->result();


And this is my view: (Edited)

foreach ($data as $d){?>
    <label>Nombre: </label>
    <input type="text" value="<?php echo $d->nombre;?>" />
<?php } ?> 

What I'm doing wrong?

我是使用codeigniter的新手。 我正在尝试显示数据库中的项目,但我不知道 知道为什么它不起作用。 请你帮我吗?


 功能Usuario扩展CI_Controller {
  function construct(){
 parent :: __ construct(); 
 $ this-&gt; load-&gt; model('usuario_m'); 
 public function modificar_usuario(){
 $ id_usuario = 1;  
 $ this-&gt; load-&gt; model('usuario_m'); 
 $ data ['resultado'] = $ this-&gt; usuario_m-&gt; ver_datos_usuario($ id_usuario); 
 $ this-&gt;  load-&gt; view('paginas / modificar_usuario',$ data); 

这是我的模型: \ n

  public function ver_datos_usuario($ id_usuario)
 $ this-&gt; db-&gt; select('nombre','apellido','nro_ci','direccion','email  ','telefono','password'); 
 $ this-&gt; db-&gt; where('id_usuario',$ id_usuario); 
 $ this-&gt; db-&gt; from('usuarios');  
 $ query = $ this-&gt; d  b-&gt; get(); 
返回$ resultado = $ query-&gt; result(); 

这是我的观点 :(已编辑)

&lt; head&gt; 
&lt; html&gt; 
&lt; body&gt; 
foreach($ data as $  d){?&gt; 
&lt; label&gt; Nombre:&lt; / label&gt; 
&lt; input type =“text”value =“&lt;?php echo $ d-&gt; nombre;?&gt;”  /&gt; 
&lt; / body&gt; 
&lt; / html&gt;

    Change this

    foreach ($data as $d){?>

    as following

    foreach($resultado as $d){?>

    because you are sending resultado to view in $data array so now $resultado can be access as returned result from model

    One more suggestion

    Instead return result like return $resultado = $query->result(); use this return $query->result();

    Just for fun.Read docs which is about codeigniter result's

    So that you can also achieve like this...

    In view:

    foreach ($resultado as $d){?>
        <label>Nombre: </label>
        <input type="text" value="<?php echo $d['nombre'];?>" />
    <?php } ?> 

    In model:

    Change return $resultado = $query->result(); to return $query->result_array();


    1.result_array() returns result in array format.

    2.result() returns result in object format.

    Instead of using $data in the foreach iteration use $resultado. Cheers
