@hube2 thank you very much!
I found it. I have these:
add_filter('acf/load_value', array($this, 'fixArabic'), 1000);
add_filter('acf/pre_save_post', array($this, 'fixArabic'), 1000);
Their job is to replace some Arabic characters to Persian characters.
Before:
public function fixArabic($content)
{
if (!is_a($content, 'DateTime')) {
return str_replace(array('ي', 'ك', '٤', '٥', '٦', 'ة'), array('ی', 'ک', '۴', '۵', '۶', 'ه'), $content);
}
return $content;
}
After:
public function fixArabic($content)
{
if (!is_a($content, 'DateTime') && !is_array($content)) {
return str_replace(array('ي', 'ك', '٤', '٥', '٦', 'ة'), array('ی', 'ک', '۴', '۵', '۶', 'ه'), $content);
}
return $content;
}
The problem was when the $content is an array so && !is_array($content) solved the problem.
Thank you again.
But do you have any ideas why it was working with PHP7.4 and not with PHP8.0?
