||
Updates:
|
||
version 1.01 - added the $DOCUMENT_ROOT server variable to the $upload_dir
|
||
in the example.php.
|
||
|
||
version 1.02 - added the 'check_dir' method to the class. In this version
|
||
the user get an error if the defined upload-directory doesn't exsit.
|
||
|
||
version 1.10 - now the class will check if a file alreay exists. Use the
|
||
replace-property to overwrite an old file. Notice the checkbox inside the
|
||
example file: Check this box to toggle the replace-property.
|
||
|
||
version 2.00 - made this class more compact (removed some useless variables)
|
||
and added a new method(show_extensions()) to the basic class. All messages
|
||
are saved from now in the $message property (not replaced anymore) New in
|
||
this release is the multi upload example, with an extended class is it
|
||
possible to upload more then one file at the same time.
|
||
|
||
version 2.01 - added a new method: With "check_file_name()" the class will
|
||
controle if a filename uses only charcters recognized by a regular filesytem.
|
||
|
||
version 2.02 - The method upload() has boolean function now. There is now
|
||
a property to switch the method check_file_name() on or off. CHMOD = 0777
|
||
if the property $replace is set to "y".
|
||
|
||
version 2.10 - The check_file_name() method tests now the string length and
|
||
checks that the filename is not empty (I removed the file check from the upload
|
||
method). The $message property is changed into an array. This array will be
|
||
filled by the error_text() method (this method is a extended version of the
|
||
old report_error() method). Inside this method you can switch the message by the new
|
||
property $language to use translations for the output. The message output is
|
||
done by the new show_error_string() method. I did also some cleaning work and
|
||
(small) bug fixing in several methods. I changed the multi_upload_example
|
||
to work with the new error reporting methodes, too.
|
||
|
||
version 2.20 - I changed the upload() method to handle also unique filenames.
|
||
This will happen if you set the var $rename_file on true. I added also some user
|
||
friendly (dutch) messages to the main class. I isolated the function to get the file
|
||
extension into a new method: function get_extension(). Notice the new extension:
|
||
"foto_upload", these are some easy to use functions to resize an rotate
|
||
images. After the thumbnail and photo creation is done there is delete method to
|
||
remove the (orig.) uploaded file.
|
||
|
||
Version 2.21 - Added spanish messages to the class, thanks Sergio for the
|
||
translations.
