Fatal error: Uncaught Error: Function name must be a string (Responsive Google Maps WP Plugin - Metabox.php on line 115)

Question

各位开发人员和问题解决者，大家好，

我运行遇到了一个 PHP7 问题，我的代码似乎需要更新：

/home/wp-theme/public_html/wp-content/plugins/responsive-google-maps/classes/MarkAdCoreClasses/Metabox.php on line 115

我进行了一些搜索，但未能在 Stack Overflow 上的其他线程中找到这个特定问题。我对 PHP 有点熟悉，但不是处理核心 PHP 文件的专家。我更像是一名 front-end/full-stack 开发人员。

Source code: Metabox.php on line 115

$field_output .= $this->form_fields->$field['type'](array($field, $settings['metabox_id'], $passed_values));

如果有人能帮助我，我将不胜感激。提前致谢。

Answer 1

第 115 行似乎在调用一个动态函数，其名称是从 form_fields 对象中数组类型的 $field 变量中检索的。

几年前 CodeCanyon 项目页面上似乎确实报告过同样的问题 here。

我建议重新下载插件并将其上传到网站上的 /wp-content/plugins/ 文件夹，看看最新的更新是否解决了问题。

Answer 2

设法修复它，我是对的。

变化

$field_output .= $this->form_fields->$field['type'](array($field, $settings['metabox_id'], $passed_values));

到

$field_output .= $this->form_fields->{$field['type']}(array($field, $settings['metabox_id'], $passed_values));
