Php – How to set custom error message zend form element file

elementfilePHPvalidationzend-framework

So I am using Zend and I have a Zend form with a Zend_Form_Element_File and three validators:
1. setRequired
2. Extension
3. Size

 $this->browse = new Zend_Form_Element_File('Browse');
 $this->browse->setRequired(false)->removeDecorator('errors')->removeDecorator('label')
->addValidator('Extension', true, 'pdf')->addValidator('Size', false, 2000000);

I want to set custom error messages for these validators but do not know how.

The reason I want to set a custom error message is because I have a custom decorator with which I grab all errors when the form is not valid with isValid() and display them at the top of the form. The method for which I am grabbing errors in the form is getErrors().

I've also tried: http://www.mail-archive.com/fw-general@lists.zend.com/msg25779.html
by doing:

 $validator = new Zend_Validate_File_Upload();
 $validator->setMessages(array('fileUploadErrorNoFile' => 'Upload an image!''));

and doing

 $this->browse->addValidator($validator);

Any help?

this is how i use to set custom validator message.

$file = new Zend_Form_Element_File('file');
$file->setLabel('File Label')
     ->setMaxFileSize('512000')
     ->addValidator('Count', true, 1)
     ->addValidator('Size', true, 512000)
     ->addValidator('Extension', true, 'jpg,jpeg,png,gif');

$file->getValidator('Count')->setMessage('You can upload only one file');
$file->getValidator('Size')->setMessage('Your file size cannot upload file size limit of 512 kb');
$file->getValidator('Extension')->setMessage('Invalid file extension, only valid image with file format jpg, jpeg, png and gif are allowed.');

here are some of the links that may prove useful to understand custom validator message.

Python – How to check whether a file exists without exceptions

If the reason you're checking is so you can do something like if file_exists: open_it(), it's safer to use a try around the attempt to open it. Checking and then opening risks the file being deleted or moved or something between when you check and when you try to open it.

If you're not planning to open the file immediately, you can use os.path.isfile

Return True if path is an existing regular file. This follows symbolic links, so both islink() and isfile() can be true for the same path.

import os.path
os.path.isfile(fname)

if you need to be sure it's a file.

Starting with Python 3.4, the pathlib module offers an object-oriented approach (backported to pathlib2 in Python 2.7):

from pathlib import Path

my_file = Path("/path/to/file")
if my_file.is_file():
    # file exists

To check a directory, do:

if my_file.is_dir():
    # directory exists

To check whether a Path object exists independently of whether is it a file or directory, use exists():

if my_file.exists():
    # path exists

You can also use resolve(strict=True) in a try block:

try:
    my_abs_path = my_file.resolve(strict=True)
except FileNotFoundError:
    # doesn't exist
else:
    # exists

Python – How to copy a file in Python

shutil has many methods you can use. One of which is:

from shutil import copyfile
copyfile(src, dst)

# 2nd option
copy(src, dst)  # dst can be a folder; use copy2() to preserve timestamp

Copy the contents of the file named src to a file named dst. Both src and dst need to be the entire filename of the files, including path.
The destination location must be writable; otherwise, an IOError exception will be raised.
If dst already exists, it will be replaced.
Special files such as character or block devices and pipes cannot be copied with this function.
With copy, src and dst are path names given as strs.

Another shutil method to look at is shutil.copy2(). It's similar but preserves more metadata (e.g. time stamps).

If you use os.path operations, use copy rather than copyfile. copyfile will only accept strings.
