Why? (A Wordpres/logic/PHP question)
I was debugging a new theme I downloaded. The theme came with it’s own Tags page (tags.php). The issue was no posts were showing up on the page. So, I went about debugging it.
At one point I thought I’d check to see if have_posts() actually said it “had posts”. so, right before the “if (have_posts())” I added
I didn’t know if I’d get a value displayed or not, but it was worth a try. Imagine my surprise when the next time the page was displayed, it had posts on it.
Wanting to make sure I wasn’t seeing things, I then removed the echo statement and re-saved the page. On the next page refresh the posts were again missing.
So, can someone explain to me what happened? How could adding the
right before the “if” have made the script suddenly work?
And should I leave the echo there, or will it cause problems down the road? Should I remove it and figure out something else?
