[ErrorException] Warning: fopen(): Filename cannot be empty about feedbundle

Hi @ayoob-faraji,

Thank you for creating this issue.

I can't reproduce it, are you using something particular in your Kernel class?

The command is trying to open (and should create if not exists) <kernel root dir>/web/rss.xml file. Unfortunately, I don't know why it can't in your case.

Can you provide me additional information or try to debug the filepath in the vendor\eko\feedbundle\Eko\FeedBundle\Command\FeedDumpCommand.php file?

@ayoob-faraji,

Ok cool if you could resolve this issue.

Not sure to understand what you talk about, do you want to add multiple entities under different XML nodes (blog, news, radio) in your feed?

[ayoob-faraji]

@eko
no, I have a article entity that has included 3 categories : blog , news and radio
I want file rss.xml includes 3 links blog , news and radio
so if click each of links to go to the page and list to bring it

Hi @ayoob-faraji,

This can be achieved by adding a GroupItemField with 3 ItemFields.

It could be something like this:

$feed->addItemField(new GroupItemField('categories',
    new ItemField('blog', 'getFeedBlogLink'),
    new ItemField('news', 'getFeedNewsLink'),
    new ItemField('radio', 'getFeedRadioLink')
));

All you have to do is to implement 3 methods in your entity getFeedBlogLink(), getFeedNewsLink() and getFeedRadioLink().

This should output the following XML:

<entry>
    ...
    <categories>
        <blog>YOUR getFeedBlogLink() returned value</blog>
        <news>YOUR getFeedNewsLink() returned value</news>
        <radio>YOUR getFeedRadioLink() returned value</radio>
    </categories>
</entry>
