Example of writing two Codeigniter files for batch upload controller and codeigniter

Example 1:

/*** Multifile upload *** @ author Dream <dream@shanjing-inc.com> */public function multiple_uploads () {// load the required class library $ this-> load-> library ('upload'); // configure the upload parameter $ upload_config = array ('upload _ path' => '', 'allowed _ types' => 'jpg | png | gif ', 'max _ size' => '123', 'max _ width' => '123 ', 'max _ height' => '123',); $ this-> upload-> initialize ($ upload_config ); // cyclically process the uploaded file foreach ($ _ FILES as $ key => $ value) {if (! Empty ($ key ['name']) {if ($ this-> upload-> do_upload ($ key )) {// print_r ($ this-> upload-> data ());} else {// upload Failed echo $ this-> upload-> display_errors ();}}}}

Example 2:

Function upload () {$ config ['upload _ path'] = '. /uploads/';/* Here, uploads is relative to index. php, that is, the entry file. Do not make a mistake! Otherwise, The error "The upload path does not appear to be valid. "; */$ config ['allowed _ types '] = 'gif | jpg | png';/* I tried to upload other types of files. Pay attention to the sequence here! A problem was encountered while attempting to move the uploaded file to the final destination. This error is generally because the file name to be uploaded cannot be A Chinese name. This is depressing! Not solved yet. You can use other methods to solve the problem by modifying the file name! $ Config ['allowed _ types'] = 'zip | gz | png | gif | jpg '; (correct) $ config ['allowed _ types'] = 'png | gif | jpg | zip | gz '; (error) */$ config ['max _ size'] = '000000'; $ config ['max _ width'] = '000000 '; $ config ['max _ height'] = '000000'; $ config ['file _ name'] = time (); // do not use the original name $ this-> load-> library ('upload', $ config); if (! $ This-> upload-> do_upload () {echo $ this-> upload-> display_errors ();} else {$ data ['upload _ data'] = $ this-> upload-> data (); // file Information $ img = $ data ['upload _ data'] ['file _ name']; // obtain the file name echo $ img. "<br>"; foreach ($ data ['upload _ data'] as $ item => $ value) {echo $ item. ":". $ value. "<br> ";}}}

What are the issues with CodeIgniter access?

The absolute path obtained after the codeigniter file is uploaded

You can set the upload directory by using the upload class.
So at this time, you actually know the direct directory, and the corresponding stored database only needs to store the file name.

If the directory is changed (for example, by year, month, or day), because you know it in advance, you can also organize the corresponding relative path to store it in the database.

If it is written in the corresponding configuration file, you can use
