Apostrophes in {content} that’s then used in PHP shortcode cases fatal error
-
I have a shortcode [location] that’s set up in Post Snippets. I want it to be able to have content pulled from the editor, have the shortcode execute PHP code, and have it possible to have an apostrophe in the content.
For example, I have
[location category="food"] <strong>John's Rib Shack</strong> 123 Fake St. [/location]which is then passed through some PHP for determining other factors on the shortcode (ex. change the output depending on the category attribute).
Currently, I am unable to assign the content to a variable in my PHP code while using PHP 7.1 due to a fatal error since the apostrophe in the content escapes the variable string & then causes an error when eval’d. I tried wrapping {content} in htmlspecialchars(), but that still didn’t work.
Just wanted to let you know about this so it can be investigated & resolved since I’d imagine people would want to use apostrophes in a scenario like I described without the page it’s used on breaking.
Thanks!

Enabling wptexturize didn’t affect the issue.
Actually, I noticed my code left
{content}not outputting at all (just the one<p><em>'.ucfirst('{cat}').'</em></p>snippet was outputting for the location’s details.I tried many different ways of filtering the
{content}output to strip line breaks (this actually didn’t seem possible?), converting quotes to prevent code issues, etc. Unfortunately, this wasn’t successful so I just opted to add the shortcode directly to the theme’s functions.php file: https://gist.github.com/KZeni/dab000c9c4877148690c48abd75f1d8b#file-what-worked-php
