ThinkPHP uploads attachments and thinkphp uploads attachments.

ThinkPHP uploads attachments and thinkphp uploads attachments.

I just learned how to use the ThinkPHP framework to upload attachments (images, documents, videos, and other files)

First, you need to understand several functions in Upload. class. php (ThinkPHP/Library/Think/Upload, class, php) in the tp framework.

1: getError () gets the upload error message

2: uploadOne () Upload a single file

3: upload () upload multiple files

4: rootPath: root path for storing uploaded files

The Code is as follows:

Front-end:

<Td> product images </td> <input type = "file" name = "goods_pic"/> </td>

Controller

// Process uploaded attachment images // determine whether to upload 4: if no attachment is uploaded ($ _ FILES ['goods _ pic '] ['error'] <4) {// upload $ cfg = array ('rootpath' => '. /Public/uploads/', // Save the root path); $ upload = new \ Think \ Upload ($ cfg); // fully qualified name instantiation object // uploadOne () after the method is successfully executed, the attachment (on the server) $ file_info = $ upload-> uploadOne ($ _ FILES ['goods _ pic ']); // Save the uploaded attachment to the database splicing path // $ upload-> rootPath through the parent class upload. class. the _ get () method in php gets the configuration's rootPath $ _ POST ['goods _ big_img '] = $ upload-> rootPath. $ file_info ['savepath']. $ file_info ['savename'];}

If you have other requirements for uploading attachments, refer to the parent class Upload. class. in php, upload and configure the config parameter to select the required parameter. You only need to rewrite it in the Code $ cfg = array () above!

The configuration parameters for parent upload are as follows (you can rewrite them as required ):

Private $ config = array ('mimes '=> array (), // The MiMe type of the file that can be uploaded 'maxsize' => 0, // The size of the uploaded file is limited (0-no limit) 'exts' => array (), // The suffix of the file to be uploaded is 'autosub' => true, // The automatic subdirectory saves the file 'subname' => array ('date', 'Y-m-d'), // The subdirectory creation method, [0]-function name, [1]-parameter. Multiple parameters use the array 'rootpath' => '. /Uploads/', // Save the root path 'savepath' => '', // Save the path 'savename' => array ('uniqid ',''), // Upload File naming rule, [0]-function name, [1]-parameter, multiple parameters use array 'savext' => '', // Save the suffix of the file, if it is null, use the original suffix 'replace '=> false, // whether the same name overwrites 'hash' => true, // whether to generate the hash code 'callback' => false, // check whether a file callback exists. If an array of returned file information is 'driver '=> '', // The File Upload driver 'driverconfig' => array (), // upload driver configuration );

The above is all the content of this article. I hope it will be helpful for your learning and support for helping customers.
