Security on file browse Item in APEX

• Add the Menu item to default custom Blackberry file browser

  Hello

  I try to add the Menu item by default Blackberry file browser.

  I want to add the menu item 'PRINT' files. It is when I browse through the media-> Explore-> photo, we get a list of images and when clicked on the Menu. I expect the element menu to print it.

  I use ApplicationMenuItemRepository to achieve this. And the documentation says.

  MENUITEM_FILE_EXPLORER
          ApplicationMenuIteminstances registered with this ID appear when the file Explorer application is running.

  MENUITEM_FILE_EXPLORER_BROWSE
          ApplicationMenuIteminstances registered with this ID appear when a user uses the Windows Explorer application to browse files and folders.

  MENUITEM_FILE_EXPLORER_ITEM
          ApplicationMenuIteminstances registered with this ID appear when a user uses the file Explorer application to open a file.

  Whence this Explorer of files mentioned in the CIHI means. I added the Menu item in the browser, and I could see the IMPRESSION here. But I don't know where this IMPRESSION would be visible IF we add the menu item to one of them.

  Thanks in advance.

• File browse point questions...

  Hi all..
  
  Please help me with these questions on the point of ""file_browse"
  
  I have a file browse the element on a page, as in the following application.
  
  http://Apex.Oracle.com/pls/Apex/f?p=62812:1
  
  (1) when the user select a file with the Browse button, we get the
  '' ' file path' ' ' in the text field.
  

  Is it possible to validate (via javascript or any other way), whether that particular
  ""file path"" is correct and a valid file exist as per the ""file path""??

  The reason for this validation is, sometimes, our users will copy the "" file path"" instead of using the
  Browse folder button.
  
  
  (2) http://apex.oracle.com/pls/apex/f?p=62812:1
  
  If users enter a valid, but on the page in question if path I validations,
  If none of the checks fails, the compensation of the "" file path"" entered by the user.
  

  Is it possible to retain the ""file_path"" that the users entered? even if any validations fail?

  EX: on the next page
  http://Apex.Oracle.com/pls/Apex/f?p=62812:1
  
  Please
  (i) select a valid file in the element "" Browse file"" and
  (II) "" do not select any selection list "" value
  (III) click Download.
  validation will be fired and path of the file get authorized.
  
  Thank you

  COLLEGE. just curious, what security question catch one, if the element to browse file retains the "" file path"" they previously selected...

  The question is not the server now file "previously selected", but maliciously change the value to capture a file that the user cannot have intended to submit (by example/etc/passwd) when the invalid page is returned.

  every time, when little validation fails, ' 'user must reselect this file. ??

  For their own safety, Yes.

  even it is in session... for a common State, he feels that he was allowed out and will need to ' "reselet" ' the file again... ".

  It is recommended to clean all files subject to validations related APEX_APPLICATION_FILES stops working.

  Y at - there no other solution for this problem? or is it (file browse article) just how it behaves?

  In order to ensure a safe and secure environment web is how he's got to behave.

  Good user interface design can be used to minimize the impact on users by isolating classify them the navigation items on different pages for items that are prone to failure of the validation by the use of pages multiple assistants etc.

  There is an available plugin element that does, but he has a right to license for commercial use.

  This is a very controversial topic and you will find information on how to apply it if you search in the forum or on the web for "download of multiple files to oracle apex.

• File browse JavaScript does not

  Hi all
  
  
  -What is there far to JavaScript events to work for items to browse to files? I want to activate another button when the file browse has some value.
  
  Thank you
  Fadi.

  My bad. In earlier versions of the APEX, it was possible to get the full path of the item you download. I think that since 3.0 or 3.1, this has changed. Now you get only the name of the file.

  Samare,

  Here you will find an example for the deactivation and activation of the buttons:

  http://Apex.Oracle.com/pls/OTN/f?p=31517:143

  and here:

  http://Apex.Oracle.com/pls/OTN/f?p=31517:15

  You can see browse the code for reading the content of the file element.

  By combining the two scripts, you can enable or disable buttons based on the content of the file navigation feature.

• Hide the download link of file browse point

  Hello.
  
  How can I hide the download link of file browse point, we show that when the article is not empty?
  
  Question for apex 3.2.

  Hello

  APEX 3.2 there is no declarative switch to do so. You should use JavaScript to remove the download link.

  APEX 4.0, the item type of "Browse file" has a new attribute 'Display Download Link' in which you can define if you want to view the download link.

• Validation and file browse

  Hello
  just a quick question on something I noticed only today.
  Imagine you have a page where you have 2 items:
  PX_NAME - type = textfield
  PX_FILE - type = file browse
  
  You have a validation for the PX_NAME is not NULL and no process for inclusion of these values to the DB. (Let me refrain No. process to insert)
  Now, when you click submit (I forgot you have a button to submit the page) and you have previously chosen a large file (let´s say 10 MB if you don't expect too much) and also with the intention of I forgot to put any value in the PX_NAME element if the validation fails, you will notice that, before the validation returns an error you will need to wait for the file to be uploaded.
  This means if you insert files 1 GB and you do not validate the hollow items javascript you'll be here for centuries before that returned an error.
  
  Is this really how it should work, or I guess things?
  
  
  
  Kind regards
  Alexander.

  Is this really how it should work, or I guess things? >

  That's how it should work. Think about it: APEX runs in the database, and cannot do any treatment, including validations - until he received the data sent to the web server by the browser to mod_plsql. With respect to the web and the browser server is concerned it is just data form. Await you on the original of the form submission, before he gets to the APEX.

  If it is expected that, due to the size files involved, this will cause problems, then the overall application design needs to deal with. JavaScript validation on the client is a way, design the download as a process in 2 steps (e.g. with a wizard page 2) so that the value of name is submitted to and approved by APEX before allowing the user to interact with the file picker would be another.

• Validate the file browse point is not null?

  Hello, using APEX 5.0.1. I have a process that needs to run in case a file browse is not null - validation of the PL/SQL Expression. * The file storage type is: BLOB column specified in the attribute of the Source element. for example: P14_STATUS_ID_CURRENT_VALUE = 0 AND: P14_IS_CANCELLED = ' only AND: P14_FILEBROWSE_ITEM IS NOT NULL, even if I download the file, the validation fails! ??? Then I tried this validation, but no result, select FILENAME from wwv_flow_files where name =: p$ _fname and: P14_STATUS_ID_CURRENT_VALUE = 0 AND: P14_IS_CANCELLED = 'n') is this a bug? is there a work around?

  Solved: It should be: dbms_lob.getlength(:P14_FILEBROWSE_ITEM) > 0

• Validation of the file browse without stopping to download

  Hi guys,.
  
  I use Apex 4.0 and need help with the following prayer:
  
  I have a file browse point that downloads a file in the built-in WWV_FLOW_FILES. The problem is that it will post even when there is an error and my validation flags upward.
  
  Is it supposed to, is not a work around? Basically I don't want the end user to download the same file more than once.
  
  Thanks in advance to all

  I have a file browse point that downloads a file in the built-in WWV_FLOW_FILES. The problem is that it will post even when there is an error and my validation flags upward. Is it supposed to...

  Yes. The data in the file is just the same as any other form value and must be presented and sessions of State (in this case in APEX_APPLICATION_FILES) before the APEX can do something with it:

  {: identifier of the thread = 902770}

  Basically I don't want the end user to download the same file more than once.

  You will need to perform some sort of validation for it and in case of failure check, remove the unwanted file:

  {: identifier of the thread = 1772863}
