$customBBCodes = $this->getVar('comments-form-custombbcodes');
if (count($customBBCodes)) {
    foreach($customBBCodes as $code) {
        if ($code->button_enabled) {

            $close_tag = $code->button_close_tag;
            $icon = $code->button_image;
            $css = $code->button_css;
        }
    }
}

I am running this script in my Joomla 3.0 application with PHP7.3 on Apache.

Solution

  • must add
    if(is_array($customBBCodes)){

    all change to

       `$customBBCodes = $this->getVar('comments-form-custombbcodes');
    if(is_array($customBBCodes)){
        if (count($customBBCodes)) {
            foreach($customBBCodes as $code) {
                if ($code->button_enabled) {
                    $k = 'custombbcode' . $code->id;
                    $title = trim(JCommentsText::jsEscape($code->button_title));
                    $text = empty($code->button_prompt) ? JText::_('BBCODE_HINT_ENTER_TEXT') : JText::_($code->button_prompt);
                    $open_tag = $code->button_open_tag;
                    $close_tag = $code->button_close_tag;
                    $icon = $code->button_image;
                    $css = $code->button_css;`
