Import Image Into Existing Class

Friday 06 February 2004 2:52:30 am

Hi,

It depends on which eZ publish are you using. If you are using eZ publish 3.1 or 3.2, you can refer to import scripts listed in the Contributions section and find out how to import image. If you are using eZ publish 3.3, you need to use following saveImage function:

function saveImage( $sourceImage, $originalImageFileName, $caption, &$contentObjectAttribute )
{
    $content =& $contentObjectAttribute->content();
    // $content is now an instance of eZImageAliasHandler
    if ( is_object( $content ) )
    {
        $content->initializeFromFile( $sourceImage, $caption, $originalImageFileName );
        if ( $content->isStorageRequired() )
        {
            $content->store();
        }
    }
}

I am not able to get this working. What should the values for the variables look like? So you know, I am trying to include them in the script I posted in another thread (http://ez.no/community/forum/developer/importing_update_entry_if_it_already_exists). I have tried several ways to add it, all to no avail. The function you posted is inserted in the script, here is the code I am using to try to call the function:

if ($contentClassAttribute->attribute("name") == "Image")
  {
    saveImage ('/PATH_TO_SITE/ez/design/admin/images/logo.gif', 'logo.jpg', 'The logo', &$contentObjectAttribute);
  }

At the moment I am using the eZ logo for testing purposes. I am sure that I am missing sometihng obvious, but I can't put my finger on it.

Thanks for the help!

Actually, I just discovered that the image is stored when I use a path from the server's root (not Web root). <b>But</b> the image is not associated with the entry, even though it is included in the right(?) spot within my import script. Confusing, but it's progress...

FYI: Here is the code I am using within my import script.

[The Function]

function saveImage( $sourceImage, $originalImageFileName, $caption, &$contentObjectAttribute )
{
  $content =& $contentObjectAttribute->content();
  // $content is now an instance of eZImageAliasHandler
  if ( is_object( $content ) )
  {
    $content->initializeFromFile( $sourceImage, $caption, $originalImageFileName );
    if ( $content->isStorageRequired() )
    {
      $content->store();
    }
  }
}

[Attribute Import]

if ($contentClassAttribute->attribute("name") == "Image")
  {
    saveImage ('/PATH_FROM_SERVER_ROOT/image.jpg', 'image.jpg', 'Image Caption Text', &$contentObjectAttribute);
  }

I do have an image object within the class, it is named 'Image'.

Some more information:

Below are two versions of the data_text for the ezcontentobject_attribute associated with the proper contentobject_id. The first is the one that is created by the import code (above) and is broken. The second was created when I edited the same document via the online editor and added the image manually,

         timestamp="1077036457"
         is_valid="1" />
</ezimage>

Several things stand out:
1. The working version contains much more information.
2. The <i>filename</i> in the broken version doesn't include the extension (jpg), <i>is_valid</i>, <i>suffix</i> and many other fields are empty.
3. No Aliases were created.

Where is the disconnect?

Your code looks correct. Have you checked read/write permissions on both the source and the destination folder? Mabye the user you the the import script as doesn't have proper permissions?

If I read kernel code correctly, it works as follows (concerning initializeFromFile($filename, $caption, $origfile))
- checks if $filename exists, fails if not,
- sets $origfile to $filename if the former is null,
- finds out MIME type of $origfile
- generates new filename from MIME type
and so on. Looks like MIME type check fails in this case, perhaps $filename exists, but $origfile doesn't?
Or is it in wrong directory? Try omitting $origfile.

Nathan, thanks for posting! I had solved the problem previously, and neglected to post an update here. Sorry! Now that the site is almost complete (we've done a quiet launch, and are about to announce the site), I will try to post a complete version of my import script. Part of the issue I ran into was due to a problem in the kernel code, which the fine folks at eZ systems (Wenyue!) were very helpful in tracking down. I believe the issue has been solved in an update, so it shouldn't plague others. :)

For those of you pondering it, the support contracts are well worth it. Wenyue saved me a lot of time and ended my frustrations.
