我无法通过连接mysql数据库中的firstname和lastname来填充下拉列表。我尝试了一些查询,但似乎都没有。我知道我的查询中有错误,但无法弄清楚发生了什么。此外,我已将下面的MVC代码与我的表格一起粘贴。
我的控制器代码是:exits.php
function admin_add_absconding(){
global $SITE,$USER;
$data = array();
$data['row'] = new stdClass();
$data['row'] = $this->admin_init_elements->set_post_vals($this->input->post());
$data['offices']=$this->mod_common->get_all_offices();
$clients = currentuserclients();
$data['roles'] = $this->mod_common->get_cat_array('designation','status',"1' AND id > '0",'designation');
get_city_state_country_array($data,array('cityid'=>$data['row']->cityid));
$data['error_message'] = '';
$data['row']->id = $this->uri->segment(3);
$data['id'] = $this->uri->segment(3);
$data['action'] = 'add';
$data['heading'] = 'Add';
$data['msg_class'] = 'sukses';
$data['path']=$path;
$post_action = $this->input->post('action');
$data['groups'] = $this->exit_common->get_all_names();
if($post_action=='add' || $post_action =='update' ){
$post_array = $this->input->post();
$action = ($post_action == 'add')?'inserted':'updated';
//echo '<pre>';print_r($SITE);die;
echo $post_array['exit_type'] = 'Employee Initiated';
if($data['error_message'] == 'Record '.$action.' successfully'){
$data['row'] = new stdClass();
$data['row']->id = $this->uri->segment(3);
$data['row']->status = 1;
}
}
我的型号代码是:exit_common.php
function get_all_names(){
$query = $this->db->query('SELECT firstname,lastname FROM pr_users_details');
echo $this->db->last_query();
die;
return $query->result();
}
我的观看代码是:backend_add_new_exit.php
<select class="form-control">
<?php
foreach($groups as $row)
{
echo '<option value="'.$row->firstname.'">'.$row->lastname.'</option>';
}
?>
</select>

在get_all_names()
函数中,在返回结果之前回显查询和die
。 die
会立即停止您的脚本。
根据您显示的表定义,您的查询似乎没有任何错误,但除了SQL语法错误之外,还有许多可能失败的原因。

在你的模型exit_common.php上试试这个
<?php
function get_all_names(){
$query = $this->db->get('pr_users_details');
if ($query->num_rows() > 0)
{
return $query->result();
}
}
?>
On you Views使用以下代码
<select class="form-control">
<?php foreach($groups as $row):?>
<option value="<?php echo $row->firstname; ?>"> <?php echo $row->lastname; ?> </option>
<?php endforeach; ?>
</select>
希望有所帮助
