After switching to PHP8 you might encounter the following warning:
PHP Warning: Attempt to read property "ID" on null in .../zip-recipes/class.ziprecipes.php on line 1569

Here is a quick fix to check whether $post has set prior to access its properties.

First off, love the plug-in, does exactly what it says without extra bloat.

Now, the reason I made this topic. On our site we’ve disabled the WP cron and made an actual cronjob on the server. This cronjob is currently showing a repeated PHP notice.

See below the notice:
PHP Notice: Trying to access array offset on value of type null in /wp-content/plugins/theme-switcha/inc/plugin-core.php on line 81

Currently this line is this:
if (!$options['enable_plugin']) return $current;

I believe this notice can be prevented if this is changed to:
if (!isset($options['enable_plugin']) || !$options['enable_plugin']) return $current;

Could this please be implemented?

Kind Regards,
JJ

Fatal error: Cannot use isset() on the result of an expression (you can use “null !== expression” instead) in /home/…/public_html/plugins/content-aware-sidebars-admin/admin_bar.php on line 135

I had to go into my c-panel to access the php file and edit line 135 from:

if (isset(self::DOCS_MAP[$module->get_id()])) {

to

if (null !== (self::DOCS_MAP[$module->get_id()])) {

I’m not sure if this change breaks anything else, but my site is loading for now.

Please update the plugin to avoid this error in your next release.

Thank you.

a PHP error that completly crash my website.

i think this is caused by a deprecied function.

I would like to write a condition with ‘isset’. It works:

if ( isset( $_GET['fwp_hidden_tags'] )

but I also want to include “=gdgb”. How do I write this?

function exclude_tagged_posts( $query ) {
    if ( $query->is_main_query()  && $query->is_home() ) {
        $query->set( 'tag__not_in', array( 404 ) );
    }
}
add_action( 'pre_get_posts', 'exclude_tagged_posts' );

It excludes posts with a tag with ID = 404 from the search. Now, I would like to call a function from the address bar that only displays tags with ID = 404. How to do that? All I know is that you have to use a condition:

is_home() && isset( $_GET['function_name'] )

Right?

My code suddenly creates problems. When I save the page wordpress crashes und I get a text only page with zero style elements – like you open a text page in your browser.

One the frontend the page renders – but the side panel is missing.

I found the backend troublemaker, but I wonder why.

Bad code:

<?php
if(isset($_POST['imodel'])){ $mod = $_POST['imodel']; } ELSE {$mod = 'iPhone Xs'; $linkinsert ='iphone-xs';}
if(isset($_POST['imemory'])){ $mem = $_POST['imemory']; } ELSE {$mem = '64';}

if(isset($_POST['curr_option'])){$curr_option = $_POST['curr_option']; } ELSE {$curr_option = 'USD';}

Changed and working in backend:

<?php
if(!empty($_POST['imodel']) || !empty($_POST['imemory'])){
    $mod = 'iPhone Xs'; $linkinsert ='iphone-xs'; $mem = '64';
}

if(isset($_POST['curr_option'])){$curr_option = $_POST['curr_option']; } ELSE {$curr_option = 'USD';}

However, in the frontend the side-panel still disappears on reload.

Need to add that the bad code did run in PHP 5.6 (or previous WP version) without problem.

add_filter( 'yikes-mailchimp-filter-before-submission', 'maybe_supply_FNAME_to_merge_field', 10, 1 );

function maybe_supply_FNAME_to_merge_field( $merge_fields ) {
	if ( empty( trim( $merge_fields['SALUTATION'] ) ) && ! empty( $merge_fields['FNAME'] ) ) {
		$merge_fields['SALUTATION'] = $merge_fields['FNAME'];
	}
	return $merge_fields;
}

It turns out that the expression

empty( trim( $merge_fields['SALUTATION'] ) )

always returns TRUE, whether the subscriber has entered a value in the SALUTATION field of the form or not.

I have confirmed that the merge field SALUTATION is correctly set in the Yikes form

I have also tried the expression:
!isset( $merge_fields['SALUTATION'] )
with the same result.

So how to fix that?

I’m trying to check if am variable is set in GET method but if(isset($_GET['thread_id'])) not working because wordpress link is: https://beta.onemillionnights.com/chat/?thread_id=57 and / before ? in link stops execution of the isset function?

How can fix it?
Thanks

Every time I try to save changes made to the plugin on settings page, I get the above errors. I’m not sure if this is a plugin conflict or not. Just letting you know.
