Hi, I'm using Metabox with Oxygen Builder. I've created a Custom Field Group for some pages.
In these fields I have a cloneable group with several sub fields. One of these is a Switch that show or hide other sub fields.
In Oxygen Builder I used a Code Block to show the cloneable group with html and php and it worked well.
After switching to php 8, many warnings appear in frontend as these:
Warning: Undefined array key "gara_contvar_btn" in .../wp-content/plugins/oxygen/component- framework/components/classes/code-block.class.php(133) : eval()'d code on line 9
Warning: Undefined array key "gara_contvar_btntxt" in .../wp-content/plugins/oxygen/component- framework/components/classes/code-block.class.php(133) : eval()'d code on line 10
Warning: Undefined array key "gara_contvar_btnurl" in .../wp-content/plugins/oxygen/component-framework/components/classes/code-block.class.php(133) : eval()'d code on line 11
And these are the first rows in the code block:
2 $group = rwmb_meta( 'gara_contvar' );
3 foreach( $group as $value):
...
9 $btn = $value['gara_contvar_btn']; // switch field
10 $btn_txt = $value['gara_contvar_btntxt']; // text field without default value
11 $btn_url = $value['gara_contvar_btnurl']; // url field without default value
I saw that if the switch is Off, no value is set in the database, so the warning. And the same if I have a text or url field empty (the switch of line 9, hide or show the fileds of line 10 and 11).
Can you help me to remove these warnings? Thanks
Daniele
