能够为每个分机显示正确的图标但是当我上传文件例如ppt文件时出现问题我的显示器中的每个其他文件（div）都采用该图标并且我有pdf / doc / ppt我的目录中的文件。我希望每个文件都根据其图标显示。切换条件工作正常，因为当我选择doc / pdf / ppt文件时，它会显示图标，但所有其他文件都会显示该图标。
我哪里出错？
在此先感谢您的帮助。
答案 0 :(得分：0)
经过多天后，我找到了解决问题的方法，我只需要使用switch语句在数据库中插入相应的文件图标路径，然后从数据库中获取图标路径。
控制器中的* * upload.php
<?php
class Upload extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
}
public function index()
{
$this->load->view('upload_success', array('error' => ' '));
}
public function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'doc|docx|ppt|pptx|pdf|xls|xlsx';
$config['max_size'] = 0;
$config['max_width'] = 3024;
$config['max_height'] = 1768;
$this->load->library('upload', $config);
if (!$this->upload->do_upload('userfile')) {
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_success', $error);
} else {
$data = array();
$this->load->library('upload', $config);
$fileData = $this->upload->data();
$ext = $this->upload->data('file_ext');
switch ($ext) {
case ".docx":
$icon = "\docss\images\word.png";
break;
case ".pdf":
$icon = "\docss\images\pdf.jpg";
break;
case ".pptx":
$icon = "\docss\images\ppt.png";
break;
default:
echo "sorry there was an error uploading your file!!!";
}
$uploadData['full_path'] = $fileData['full_path'];
$uploadData['file_name'] = $fileData['file_name'];
$uploadData['created'] = date("Y-m-d H:i:s");
$uploadData['modified'] = date("Y-m-d H:i:s");
$uploadData['file_icon'] = $icon; //the path of the approriate file icon to insert in db
}
if(!empty($uploadData)){
//Insert file information into the database
$this->db->insert('files',$uploadData);
$confyg = array(
'source_image' => $fileData ['full_path'],
'new_image' => './uploads/thumbs/',
'maintain_ration' => true,
'width' => 150,
'height' => 100
);
$this->load->library('image_lib', $confyg);
$this->image_lib->resize();
$this->load->model('upload_model');
$data['icon'] = $this->upload_model->getaimage();
$this->load->view('upload_success', $data);
}
}
}
?>
之后，代码按照我的意愿运行。 希望它能帮助另一个想要上传和显示适当文件图标的人。
