[英]Controller not calling model function
我正在嘗試調用函數get_owner($id)
以獲取用戶名,但它一直在說:遇到PHP錯誤
Severity: Notice
Message: Trying to get property of non-object
Filename: incident/detail_page_admin.php
Line Number: 54
視圖:
<p id ="detail_owner">Criador do Incidente: <?php echo $incident_own->name;?></p>
控制器:
$aux = $this->incident_model->count_incident($this->session->userdata('usuario_id'));
$avatar = $this->usuario_model->get_avatar($this->session->userdata('usuario_id'));
$incident_owner = $this->usuario_model->get_owner($id);
$this->load->view('template/cabecalho');
$b = $this->incident_model->get_incident_by_id($id);
$this->load->view('incident/detail_page_admin', array('incident_own' => $incident_owner, 'count_incident' => $aux, 'incident_show_by_id' => $b, 'avatar_array' => $avatar));
$this->load->view('template/rodape');
模型:
function get_owner ($id){
$a = $this->db->query('select name from usuario where id = ?', array($id));
return $a->result();
}
而不是在模型函數中返回$a->result()
,而是要返回$a->row()
,然后它應該可以工作。
function get_owner ($id){
$a = $this->db->query('select name from usuario where id = ?', array($id));
return $a->row();
}
但是,返回$a->row()
只會返回一行,如果只期望一行,那很好。 但是,如果您希望返回多行,則可以執行
function get_owner ($id){
$a = $this->db->query('select name from usuario where id = ?', array($id));
return $a;
}
然后,您想像這樣遍歷視圖中的結果行
<?php foreach ($incident_own->result() as $row)
{ ?>
<p id ="detail_owner">Criador do Incidente: <?php echo $row->name;?></p>
<?php } ?>
