WP: 5.0.2
\nPHP: recently updated 5.6 > 7.2<\/p>\n

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. <\/p>\n

One the frontend the page renders – but the side panel is missing.<\/p>\n

I found the backend troublemaker, but I wonder why.<\/p>\n

Bad code:<\/p>\n

<?php\nif(isset($_POST['imodel'])){ $mod = $_POST['imodel']; } ELSE {$mod = 'iPhone Xs'; $linkinsert ='iphone-xs';}\nif(isset($_POST['imemory'])){ $mem = $_POST['imemory']; } ELSE {$mem = '64';}\n\nif(isset($_POST['curr_option'])){$curr_option = $_POST['curr_option']; } ELSE {$curr_option = 'USD';}<\/code><\/pre>\n
Changed and working in backend:<\/p>\n
<?php\nif(!empty($_POST['imodel']) || !empty($_POST['imemory'])){\n    $mod = 'iPhone Xs'; $linkinsert ='iphone-xs'; $mem = '64';\n}\n\nif(isset($_POST['curr_option'])){$curr_option = $_POST['curr_option']; } ELSE {$curr_option = 'USD';}<\/code><\/pre>\n
However, in the frontend the side-panel still disappears on reload.<\/p>\n
Need to add that the bad code<\/em> did run in PHP 5.6 (or previous WP version) without problem.<\/p>\n","protected":false},"template":"","class_list":["post-11107041","topic","type-topic","status-publish","hentry","topic-tag-isset"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/11107041","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":1,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/11107041\/revisions"}],"predecessor-version":[{"id":11107121,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/11107041\/revisions\/11107121"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=11107041"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
