Hi all—

I'm running into a bit of a wall when it comes to extending the blog post module.

I've successfully added a "Featured Image" field, but I can't add a simple, varchar text field.

Here's my code:

public function subscribeEvents()
{
	Backend::$events->addEvent('blog:onExtendPostModel', $this, 'extend_blogpost_model');
	Backend::$events->addEvent('blog:onExtendPostForm', $this, 'extend_blogpost_form');
}

public function extend_blogpost_model($post)
{
	$post->add_relation('has_many',
					'featuredimage',
					array('class_name'=>'Db_File',
						  'foreign_key'=>'master_object_id',
						  'conditions'=>"master_object_class='Blog_Post' and field='featuredimage'",
						  'order'=>'sort_order, id',
						  'delete' => true
						  )
					);
		
	$post->define_multi_relation_column('featuredimage', 'featuredimage', 'Featured Image', '@name');
	$post->define_column('featured_link_text', 'Featured Link Text');
}
	
public function extend_blogpost_form($post)
{

	$post->add_form_field('featuredimage')->renderAs(frm_file_attachments)->renderFilesAs('single_image')->addDocumentLabel('Upload photo')->tab('Featured Image')->noAttachmentsLabel('Photo is not uploaded')->imageThumbSize(100)->fileDownloadBaseUrl(url('ls_backend/files/get/'));
	$post->add_form_field('featured_link_text')->tab('Featured Image');

}

To match, I've added a mysql update file:

alter table blog_posts add column featured_link_text varchar(255);

What am I missing here? The error I get is that "Render mode is unknown for featured_link_text field." But when I extend the product model, as long as the update file is there, I don't need to specify a render mode for the field.

Thanks!

Aha! Success. The problem was that in my version.dat file I had used a TAB instead of a space.

However, I still am having difficulty fixing the preview function, which puffs:

Quote

Form behavior: error in the model form elements definition. Tabs should be specified either for each form element or for none.

I couldn't find any reference to this problem online or in the docu.

Hi!

I'm not sure what causes the error. Please try to exclude your custom fields from the Preview page:

public function extend_blogpost_form($post, $context)
{
     if ($context != 'preview')
    {
        $post->add_form_field('featuredimage')->renderAs(frm_file_attachments)->renderFilesAs('single_image')->addDocumentLabel('Upload photo')->tab('Featured Image')->noAttachmentsLabel('Photo is not uploaded')->imageThumbSize(100)->fileDownloadBaseUrl(url('ls_backend/files/get/'));
        $post->add_form_field('featured_link_text')->tab('Featured Image');
    }
}

Thank you

Hi Aleksey.

Chopping them out does solve the problem, thanks!

This Code is working fine for any module to extend with image field.

But how to display that particular image at front side?

For example here how can I display futuredimage at front side?

suggest me the simple way, without writing query on db_file table its possible !!

Thank you

Hi Urvi,

There are two free third-party modules on our Marketplace which extend blog posts with images and have documentation. Please check them out:
