I’m trying to create a notification where posts over 3 years old display a warning message. I’ve bundled the following together, but it doesn’t seem to be working:
<?php
$old_post = 60*60*24*1095; // 3 years
if((date('U')-$page->published()->toDate('U')) > $old_post) {
echo '<div class="old-notice">This post is more than three years old and may contain incorrect information or <a href="/disclaimer">opinions I no longer hold</a>.</div>';
}
?>
I’m getting the following error with this snippet:
Whoops \ Exception \ ErrorException (E_USER_DEPRECATED)
Passing a single space as value to `Xml::attr()` has been deprecated. In a future version, passing a single space won't render an empty value anymore but a single space. To render an empty value, please pass an empty string.
The if logic seems to work as this error only displays on posts older than 3 years old.
Hm, the error message doesn’t seem to fit the code snippet you posted.
Could you post a screenshot of the whoops page, please?
On a side note it is not good practice to echo HTML, recommended:
<?php
$old_post = 60*60*24*1095; // 3 years
if((date('U')-$page->published()->toDate('U')) > $old_post): ?>
<div class="old-notice">This post is more than three years old and may contain incorrect information or <a href="/disclaimer">opinions I no longer hold</a>.</div>
<?php endif ?>
So fresh back from a dog walk, I’ve worked out that the issue is with 1 particular post. It was just a coincidence that that particular post is the first one that’s 3 years old or more. If I go to older ones, they display the message just fine.
Weirdly though, the same post on my live site doesn’t display an error. I checked if it was the code I’ve added, but it wasn’t, the post still bugs out locally, even when the new code is commented out. So I assume it’s something to do with the development server?
Ok, unfortunately the screenshot is cut off at the bottom where the interesting information is. Seems to be an issue with Html::img() somewhere in your template or in snippets used in your template.
