I do believe LimitWordCount will do strip_tags or something to that effect so no matter how many words you get back you'll never get the image tag.
Your best bet is probably to add an image field to the blog entry and use that instead.
You could do something like:<?php
class BlogEntryDecorator extends DataObjectDecorator {
public function extraStatics(){
return array(
'has_one' => array(
"TitleImage" => "Image"
)
);}
public function updateCMSFields(FieldSet &$fields) {
$fields->addFieldToTab("Root.Content.Main", new ImageField("TitleImage", "Title image"), 'Content');
}
}
?>And then add this to _config.php:
Object::add_extension('BlogEntry', 'BlogEntryDecorator');
After you upload the image through the image field you can display it by writing $TitleImage in the template.

How could I go about adding another field to this to allow the photo to have a caption? I'd assumed I could just amend it to this, but while the field appears in the CMS, when I save the page the data is lost. Thanks.
<?php
class BlogEntryDecorator extends DataObjectDecorator {
public function extraStatics(){
return array(
'has_one' => array(
"TitleImage" => "Image",
"PhotoCaption" => "HTMLText"
)
);
}public function updateCMSFields(FieldSet &$fields) {
$fields->addFieldToTab("Root.Content.Main", new ImageField("TitleImage", "Title image"), 'Content');
$fields->addFieldToTab("Root.Content.Main", new TextField("PhotoCaption", "Photo Caption"), 'Content');
}}
?> -

Not 100% sure but I think you might need to add your new fields to the db array also. ie
static $db = array(
"TitleImage" => "Image",
"PhotoCaption" => "HTMLText"
); -

Thanks. I tried doing that, but I wasn't sure how to it works in relation to 'return array', so couldn't get that to work.

When you're decorating you add db fields pretty much the same way you add extra relationships through decoration. The code you have is pretty close, this should work.
class BlogEntryDecorator extends DataObjectDecorator {
public function extraStatics(){
return array(
'db' => array("PhotoCaption" => "HTMLText"),
'has_one' => array("TitleImage" => "Image")
);
}public function updateCMSFields(FieldSet &$fields) {
$fields->addFieldToTab("Root.Content.Main", new ImageField("TitleImage", "Title image"), 'Content');
$fields->addFieldToTab("Root.Content.Main", new TextField("PhotoCaption", "Photo Caption"), 'Content');
}
}
Try this and build the database after changing the code. If everything's setup correctly the text field should get added to the BlogEntry table. -

Thank you so much, been trying again for the last hour but not quite getting it - but this works perfectly. I'm slowly getting the hang of how these relationships work.
