19.4. Migrating from previous versions

The API of Zend_File_Transfer has changed from time to time. If you started to use Zend_File_Transfer and it's subcomponents in earlier versions follow the guidelines below to migrate your scripts to use the new API.

19.4.1. Migrating from 1.6 to 1.7 or newer

19.4.1.1. Changes when using filters and validators

As noted by users, the validators from Zend_File_Transfer do not work in conjunction with Zend_Config due to the fact that they have not used named arrays.

Therefor, all filters and validators for Zend_File_Transfer have been reworked. While the old signatures continue to work, they have been marked as deprecated, and will emit a PHP notice asking you to fix them.

The following list shows you the changes you will have to do for proper usage of the parameters.

19.4.1.1.1. Filter: Rename
  • Old method API: Zend_Filter_File_Rename($oldfile, $newfile, $overwrite)

  • New method API: Zend_Filter_File_Rename($options) where $options accepts the following array keys: source equals to $oldfile, target equals to $newfile, overwrite equals to $overwrite

例 19.33. Changes for the rename filter from 1.6 to 1.7

// Example for 1.6
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addFilter('Rename',
                   array('/path/to/oldfile', '/path/to/newfile', true));

// Same example for 1.7
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addFilter('Rename',
                   array('source' => '/path/to/oldfile',
                         'target' => '/path/to/newfile',
                         'overwrite' => true));

                    

19.4.1.1.2. Validator: Count
  • Old method API: Zend_Validate_File_Count($min, $max)

  • New method API: Zend_Validate_File_Count($options) where $options accepts the following array keys: min equals to $min, max equals to $max,

例 19.34. Changes for the count validator from 1.6 to 1.7

// Example for 1.6
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('Count',
                      array(2, 3));

// Same example for 1.7
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('Count',
                      false,
                      array('min' => 2,
                            'max' => 3));

                    

19.4.1.1.3. Validator: Extension
  • Old method API: Zend_Validate_File_Extension($extension, $case)

  • New method API: Zend_Validate_File_Extension($options) where $options accepts the following array keys: * equals to $extension and can have any other key, case equals to $case,

例 19.35. Changes for the extension validator from 1.6 to 1.7

// Example for 1.6
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('Extension',
                      array('jpg,gif,bmp', true));

// Same example for 1.7
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('Extension',
                      false,
                      array('extension1' => 'jpg,gif,bmp',
                            'case' => true));

                    

19.4.1.1.4. Validator: FilesSize
  • Old method API: Zend_Validate_File_FilesSize($min, $max, $bytestring)

  • New method API: Zend_Validate_File_FilesSize($options) where $options accepts the following array keys: min equals to $min, max equals to $max, bytestring equals to $bytestring

Additionally, the useByteString() method signature has changed. It can only be used to test if the validator is expecting to use byte strings in generated messages. To set the value of the flag, use the setUseByteString() method.

例 19.36. Changes for the filessize validator from 1.6 to 1.7

// Example for 1.6
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('FilesSize',
                   array(100, 10000, true));

// Same example for 1.7
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('FilesSize',
                      false,
                      array('min' => 100,
                            'max' => 10000,
                            'bytestring' => true));

// Example for 1.6
$upload->useByteString(true); // set flag

// Same example for 1.7
$upload->setUseByteSting(true); // set flag

                    

19.4.1.1.5. Validator: Hash
  • Old method API: Zend_Validate_File_Hash($hash, $algorithm)

  • New method API: Zend_Validate_File_Hash($options) where $options accepts the following array keys: * equals to $hash and can have any other key, algorithm equals to $algorithm,

例 19.37. Changes for the hash validator from 1.6 to 1.7

// Example for 1.6
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('Hash',
                   array('12345', 'md5'));

// Same example for 1.7
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('Hash',
                      false,
                      array('hash1' => '12345',
                            'algorithm' => 'md5'));

                    

19.4.1.1.6. Validator: ImageSize
  • Old method API: Zend_Validate_File_ImageSize($minwidth, $minheight, $maxwidth, $maxheight)

  • New method API: Zend_Validate_File_FilesSize($options) where $options accepts the following array keys: minwidth equals to $minwidth, maxwidth equals to $maxwidth, minheight equals to $minheight, maxheight equals to $maxheight,

例 19.38. Changes for the imagesize validator from 1.6 to 1.7

// Example for 1.6
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('ImageSize',
                      array(10, 10, 100, 100));

// Same example for 1.7
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('ImageSize',
                      false,
                      array('minwidth' => 10,
                            'minheight' => 10,
                            'maxwidth' => 100,
                            'maxheight' => 100));

                    

19.4.1.1.7. Validator: Size
  • Old method API: Zend_Validate_File_Size($min, $max, $bytestring)

  • New method API: Zend_Validate_File_Size($options) where $options accepts the following array keys: min equals to $min, max equals to $max, bytestring equals to $bytestring

例 19.39. Changes for the size validator from 1.6 to 1.7

// Example for 1.6
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('Size',
                      array(100, 10000, true));

// Same example for 1.7
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('Size',
                      false,
                      array('min' => 100,
                            'max' => 10000,
                            'bytestring' => true));

                    

19.4.2. Migrating from 1.6.1 to 1.6.2 or newer

19.4.2.1. Changes when using validators

As noted by users, the validators from Zend_File_Transfer do not work the same way like the default ones from Zend_Form. Zend_Form allows the usage of a breakChainOnFailure parameter which breaks the validation for all further validators when an validation error has occurred.

So we added this parameter also to all existing validators from Zend_File_Transfer.

  • Old method API: addValidator($validator, $options, $files).

  • New method API: addValidator($validator, $breakChainOnFailure, $options, $files).

To migrate your scripts to the new API, simply add a false after defining the wished validator.

例 19.40. How to change your file validators from 1.6.1 to 1.6.2

// Example for 1.6.1
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('FilesSize', array('1B', '100kB'));

// Same example for 1.6.2 and newer
// Note the added boolean false
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->addValidator('FilesSize', false, array('1B', '100kB'));
