如何顯示動態數組值以從Codeigniter中的模型查看

Question

這是我的模型代碼：

foreach ($query->result() as $row)
{
    $data = array(
                   'ptitle' =>$row->ptitle,
                    'technology' => $row->technology,
                    'description' => $row->description,

                    );

    $this->session->set_userdata('project',$data);
}

這是我的查看代碼：

<?php
if (isset($this->session->userdata['project']))
{

     $ptitle = ($this->session->userdata['project']['ptitle']);
    $technology = ($this->session->userdata['project']['technology']);
    $description =  ($this->session->userdata['project']['description']);


}
?>

當我打印數組時顯示

Array（[ptitle] => opmp [technology] => hbh [description] => kg）Array（[ptitle] => icicse [technology] => vv [description] => bhjv）。有人可以幫我打印這個嗎價值觀

Answer 1

設置會話應如下所示

$data = array(
    'ptitle'        => $row['ptitle'],
    'technology'    => $row['technology'],
    'description'   => $row['description'],
);

$this->session->set_userdata($data);

要檢索它們，請使用

if (isset($this->session->userdata['project']))
{

    $ptitle         = $this->session->userdata('ptitle');
    $technology     = $this->session->userdata('technology');
    $description    =  $this->session->userdata('description');

}

Answer 2

如果您在SESSION中將多個存儲為數組，那么您當然也需要在視圖中使用foreach 。

從

if(isset($this->session->userdata['project']))
{
    $ptitle = ($this->session->userdata['project']['ptitle']);
    $technology = ($this->session->userdata['project']['technology']);
    $description =  ($this->session->userdata['project']['description']);
}

進入

if(isset($this->session->userdata['project']))
{
    foreach($this->session->userdata['project'] as $project)
    {
        $ptitle = $project['ptitle'];
        $technology = $project['technology'];
        $description =  $project['description'];
        echo $ptitle.'<br>'.$technology.'<br>'.$description.'<br>';
    }
}

Answer 3

嘗試像下面這樣設置數組，然后將其傳遞給會話集數據。

$project = array("project" =>
                         array(
                             'ptitle' => "ptitle",
                             'technology' => "technology",
                             'description' => "description",
                         )
                  );

$this->session->set_userdata($project);
