Portfolio page faulty display

Hello,

I'm continuing testing and trouble shooting a new update of a WordPress theme. The old version of the theme is here (sample page):
http://terrybraunstein.com/portfolio/
and it displays the Portfolio page in a proper GRID design as it should be.

and the new version is here:
http://sg.terrybraunstein.com/portfolio/
and this displays the Portfolio page as if it would be a Blog

I checked carefully the proper settings and selected its correct Template (Portfolio)

Portfolio Page grid shows only when you open one of the posts, e.g. this one:
http://sg.terrybraunstein.com/portfolio/who-is-she-2013-2014/ and close it clicking on the X in the upper right. Clicking again on Portfolio in the Menu shows the Blog design again.


I installed a WordPress plug in, Query Monitor, and there is a PHP error showing up when opening this page :
http://sg.terrybraunstein.com/portfolio/who-is-she-2013-2014/
but I don't know anything about PHP so that error message does not say anything to me. Here is the screen-shot of the error message:

What could be the reason that the Portfolio page is not displaying properly in the new version?

PHP errors can be difficult to deal with, yet they often are quite literal. Too much so sometimes.

It means what it says. The PHP interpreter found an undefined variable by the name of url. Because of this, it assumed it was a string - 'url'. Not a big help. But that pretty much assures that url at that point is expected to be passed or that it was meant to be a string. Since I'm not seeing the code, it could be a string that as a property of some object or array is meant to signify something. That's usually what that sort of error means. But it could be meant to be a literal string (unlikely).

Give this some time to sink in. Then give me any further thoughts.

Also, if I could see the PHP code that's producing this error, I might be able to contribute more.

It's also possible that this is just a non-fatal error in the PHP code and that the actual problem lies elsewhere.

I'm attaching a zip file with all the php files mentioned in the error message:
Notice Use of undefined constant url - assumed 'url' 1 wp-content/themes/yin_and_yang/includes/portfolio.php:67 load_template('~/wp-content/themes/yin_and_yang/includes/portfolio.php')
wp-includes/template.php:531

Got them. It's late here. And as I think I indicated, not sure I will be able to solve this from that - just that it will give me a better chance. I'll have a look tomorrow, or over the weekend.

You say you have recently upgraded the Yin & Yang theme but have you also upgraded the version of Wordpress it's running on? If you've only updated the theme, maybe that's the problem? You might need to upgrade the core Wordpress files too. Same for any other plugins you're using. It might be worth disabling all addons and then gradually add back and test between each additions to see if you can narrow down any conflicts.

Another thought: the Yin & Yang theme is a premium Wordpress download so if your help period from the developer has expired since your time of purchase, it might be a good idea to extend the support package you have with them as their existing customer. Changes and modifications by the original developer (who will be more of an expert in Wordpress than we are) can be built in to the core and should be compatible with future updates (both in Wordpress core files and in the theme) but small ad-hoc updates and fixes by outside coders in the here-and-now will be more general and may need further adaptations as your core changes in the future. Just something to bear in mind.

Yes, I did.

All updated as well.

I did that as a part of trouble shooting, even when all plugins are disabled the portfolio pae does not display properly.

I may suggest this to my friend (the owner of the site and the theme) whom I'm helping now if I don't succeed...

The old theme is 5 years old, so big changes were needed to be made to make the theme up to date with the latest standards, which means that some things had to be rebuilt from ground up, so a simple update of the theme does not work.

Somehow this line in the portfolio.php file maybe giving some clue?

In the error message it says:
Notice Use of undefined constant url - assumed 'url' 1 wp-content/themes/yin_and_yang/includes/portfolio.php:67

and the line 67 is:
<img class="preview-img" src="<?php echo esc_url($image[url]); ?>" alt="<?php the_title_attribute(); ?>" />

In PHP all variables begin with the '$' sign so "url" in that line isn't seen as a variable by PHP. I suspect it should be:

Code:

---

<img class="preview-img" src="<?php echo esc_url($image[$url]); ?>" alt="<?php the_title_attribute(); ?>" />

Actually, in PHP, the square bracket notation is most likely to contain a quote delimited string representing a key in an array. That's most likely the case here, although it's slightly possible the $ was intended*. Also, when error reporting is off and PHP is in one of its less strict modes, a string is assumed and there's no problem. In more strict environments, it can be a fatal error, either in PHP itself, or because the resulting string includes the error message, which breaks the intended output.

Anyways, we can fix that, but there could also be other problems, in fact three, of the four files in the zip, three have this same loose syntax. Once I have them all located and fixed, I'll send you the repaired set of files. Keep the zip you already sent me as a backup just in case.



* more often found in loops, like a foreach loop. I don't see any obvious loop in the sections of code involved here. Also, if that is the case, usually it's a more generic term, like $key. Further, I think the original error message stated it assumed 'url', not $url, though of course that isn't necessarily definitive. That said, one almost has to assume this code worked in its development environment. That would almost assure its missing quotes, not missing a $, as no level of PHP will automatically supply a missing $, though loose PHP settings will allow for missing quotes with no error.

I tried this but it does not work, no change. Thanks anyway.
