我正在一页上工作，那里有很多下拉列表和一个文本字段，我从中添加一个用户并为该用户选择一些下拉列表，然后将其发送到数据库中，然后成功插入。编辑该用户，当我单击“编辑”时，它应在我选择插入的下拉菜单中打印所有选定的下拉菜单，其他应保持不变。 我的价值在于进入数组。.我需要知道如何将数组打印到下拉列表中。
Array
(
[0] => Array
(
[printprofiles_id] => 1
[profilename] => Peter
[description] =>
[printer] => 3
[report_id] => 0
[profile_id] => 1
)
[1] => Array
(
[printprofiles_id] => 2
[profilename] => Peter
[description] =>
[printer] => 4
[report_id] => 1
[profile_id] => 1
)
[2] => Array
(
[printprofiles_id] => 3
[profilename] => Peter
[description] =>
[printer] => 5
[report_id] => 2
[profile_id] => 1
)
[3] => Array
(
[printprofiles_id] => 4
[profilename] => Peter
[description] =>
[printer] => 6
[report_id] => 3
[profile_id] => 1
)
[4] => Array
(
[printprofiles_id] => 5
[profilename] => Peter
[description] =>
[printer] => 7
[report_id] => 4
[profile_id] => 1
)
)
这是我的标准代码
public function get_profilesitems_by_id($id){
$query = $this->db->get_where('setup_printprofiles', array('profile_id' => $id));
return $result = $query->result_array();
}
这是我的控制器代码
public function printprofilesedit($id = 0){
if($this->input->post('submit')){
$this->form_validation->set_rules('profilename', 'profilename', 'trim|required');
if ($this->form_validation->run() == FALSE) {
$data['all_printers'] = $this->setup_model->get_all_printers(); // In dropdown value is coming from another table...
$data['all_profiles'] = $this->setup_model->get_all_profiles();
$data['profile'] = $this->setup_model->get_printprofiles_by_id($id);
$data['profileitem'] = $this->setup_model->get_profilesitems_by_id($id); // In this there is an array which I showed above...
$data['view'] = 'admin/setup/printprofilesedit';
$this->load->view('admin/layout', $data);
}
else{
$options = array(
'report_id' => $this->input->post('report_id_'.$i),
'printer' => $this->input->post('printer_'.$i),
);
$this->setup_model->edit_printprofiles($options);
}
}
if($options){
$this->session->set_flashdata('msg', 'Record is Added Successfully!');
redirect(base_url('admin/setup/printprofiles'));
}
else{
$data['all_printers'] = $this->setup_model->get_all_printers(); // In dropdown value is coming from another table...
$data['all_profiles'] = $this->setup_model->get_all_profiles();
$data['profile'] = $this->setup_model->get_printprofiles_by_id($id);
$data['profileitem'] = $this->setup_model->get_profilesitems_by_id($id); // In this there is an array which I showed above...
$data['view'] = 'admin/setup/printprofilesedit';
$this->load->view('admin/layout', $data);
}
}
这是我的printprofilesedit.php，其中有HTML代码...我仅显示了4个下拉列表，但下拉列表超过50个。正如我提到的，只有那些我在插入时选择的下拉菜单才能填充。
