Post返回NULL

Question

我正在尝试获取上传文件的内容。但是post值返回NULL。但是$_FILES值正在变得正确。还试过$this->input->post()但它仍然返回NULL。

查看：（upload_contacts.php）

    <form enctype='multipart/form-data' method='POST'>
    <table>
        <tr>
            <td>
            Choose a file to upload: <input name='uploadedfile' type='file' />
            </td>
            <br/>
        </tr>
        <tr>
            <td>
                <input type='submit' value='submit' />
            </td>
        </tr>
    </table>
</form>

控制器：（contact.php）

public function uploadCSV()
{   
    //todo : Crate view 

    $this->config->load('je_settings',TRUE);
    $tally_folder_path = $this->config->item('folder_path');
    if(! empty($_FILES['uploadedfile']['name']))
    {
        var_dump($_FILES['uploadedfile']['name']);
        var_dump($_POST);
        die();
        $file_type = $_FILES['uploadedfile']['type'];
        $allowed = array('text/csv','text/comma-separated-values');
        if( ! empty($_FILES['uploadedfile']['name']) && in_array($file_type, $allowed))
        {
            $tally_src_file = $tally_folder_path . basename( $_FILES['uploadedfile']['name']);
            move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $tally_src_file);
        }
        else
        {
            die("No file specified or Format not supported");
        }
        $path = "sudo chmod 777 ".$tally_src_file;
        shell_exec($path);
        $this->user($tally_src_file);

Answer 1

您必须为提交输入设置名称

 <input type='submit' value='submit' name="submit" />

Answer 2

也许您在form_action="abc.xyz"中遗漏了<form enctype='multipart/form-data' method='POST'>，因此它返回NULL值
