I have been running through all the tutorial videos on your site but ran into a few issues where what seems to work in the vid does not work for me. Granted I am new to all this so highly likely to have made a mistake...however here is my issue (for whatever reason I cannot post this as a question against the actual lesson):

For some reason $Photo and $Brochure (these are created as part of the 'has_one' call in ArticlePage.php) are not acceptable calls when put in ArticlePage.ss. So when using the conditional statement to check if there is a brochure(pdf) attached to the article page it never evaluates to true.
Similar for the $Photo on articlepage.ss in that any call to $Photo never finds anything . However $Photo.CroppedImage(242, 156) does work when put in the ArticleHolder.ss
I noticed that using $BrochureID in a conditional statement work in ArticlePage.ss but not $Brochure or $Photo.

Tried using Code repository versions of ArticlePage.ss and ArticlePage.php in case I have made mistakes but still the same.

Any suggestions on what could be going wrong here?

Hei

what about

$Photo.Filename 
$Brochure.URL

Are you getting paths if u add those in your ArticlePage.ss template?

What's code in your ArticlePage.php?

Example:

class ArticlePage extends Page {
private static $has_one = array(
    'Photo' => 'Image',
    'Brochure' => 'File'
    );
    public function getCMSFields() {
        $fields = parent::getCMSFields();
		$fields->addFieldToTab("Root.Main", new UploadField('Photo'));
        	$fields->addFieldToTab("Root.Main", new FileField('Brochure'));
        return $fields;
    }
}

Did u made /dev/build/?flush=all after you added changes to your ArticlePage.php file?
Also you should run development site in dev mode, so you can get errors after you make dev/build/?flush=all

Using $Photo.Filename or $Brochure.URL does nothing as calls to $Photo and $Brochure do nothing.
To clarity using $Photo.setWidth(750) in ArticlePage.ss like in the tutorial, fails to inject the image into the html. I.e. when I inspect the source of the actual page there is no <img> tag present unlike on the page that has type ArticleHolder which seems to accept calls like $Photo.CroppedImage(242, 156) and inserts the correct img tag with src etc.

Forgot to mention that I always remember to build and flush so that is not the issue.

Tried putting site in dev mode...no errors

Originally I had in ArticlePage.ss, exactly as shown in the video:

 <div class="blog-main-image">
					$Photo.SetWidth(750)
					<div class="tag"><i class="fa fa-file-text"></i></div>
				</div>

Then tried copying the ArticlePage.ss from the tutorial so have:

<div class="blog-main-image">
				<% with $Photo.SetWidth(750) %>
					<img src="$URL" width="$Width" height="$Height" class="my-custom-class">
				<% end_with %>
					<div class="tag"><i class="fa fa-file-text"></i></div>
				</div>

Using the tutorial code repository version injects the <img> tags but like this

<img src="" width="" height="" class="my-custom-class">

So clearly the $Photo calls are not working at this page level

Hei,

I think problem is somewhere else not in template. What's code in your ArticlePage.php, ArticleHolder.php and Page.php?

Also maybe there is some kind of conflict?
You can try to change $Photo to $Photo2 for example, both in ss and php files (in case some plugin etc already have $Photo in use).

Thank you for your assistance and you were very much correct. The problem was I had inadvertently changed the name of the ArticlePage_Controller in ArticlePage.php so the controller was not picking up anything.

All sorted now. Cheers
