Question

我试图将图像上传到指定的文件夹，但无法弄清楚为什么控制器功能不起作用。这是控制器代码

public function do_upload()
{
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = '400';
    $config['max_width']  = '1024';
    $config['max_height']  = '768';

    $this->load->library('upload',$config);
    if($this->upload->do_upload()){
        echo "image uploaded";
    }

    echo $this->input->post('username');
}

这是在视图文件夹中输入图像文件的表单

<form enctype="multipart/form-data" method="post" action="<?php echo    site_url('welcome/do_upload');?>">
username:<input type="text" name="username">
<p>upload file</p>
<input type="file" name="image">
<input type="submit" name="submit" value="submit">
</form>

你只需要在do_upload函数中传递文件输入名称'image'，默认情况下是'userfile'

public function do_upload()
{
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = '400';
    $config['max_width']  = '1024';
    $config['max_height']  = '768';

    $this->load->library('upload',$config);
    if($this->upload->do_upload('image')){ //passed 'image' file control input name in form
        echo "image uploaded";
    }

        echo $this->input->post('username');
 }

图像未上传到codeigniter中的指定文件夹
