$wpdb is not initiating

时间：2018-02-14 作者：ishtiaq

我是wordpress新手，想创建一个插件，但是$wpdb 未启动，我正在使用wordpress版本4.9.4

这是我的代码片段

global $wpdp;
$sql    = \'SELECT * From \'.$wpdp->prefix.\' my_first_plugin\';
$result = $wpdp->get_results($sql);

您在代码示例中错误地编写了$wpdb（3x）。如果它是一个精确的副本，它将永远不会工作。SQL中前缀后面有一个空格。”不应该在那里。“From”应该是所有的大写字母。

尝试以下操作：

global $wpdb;
$sql    = \'SELECT * FROM \' . $wpdb->prefix . \'my_first_plugin\';
$result = $wpdb->get_results($sql);

结束
