現在，我使用這個類。
class MarketPress_data {
public function get_countries() {
//load data structures
require_once(WP_PLUGIN_DIR.'/marketpress/marketpress-includes/marketpress-data.php');
return $this->countries;
}
}
$MarketPress_data = new MarketPress_data;
，然後用試圖將數據輸出：
foreach ($MarketPress_data->get_countries() as $key => $val) {
echo $key . ' = ' . $val;
}
現在的問題是我得到這個。
Fatal error: Call to a member function get_countries() on a non-object
請幫忙，因爲我不知道我在這裏錯過了什麼。
由於某些原因，這在我的PHP 5.3.20中適用。我不確定當你沒有在你的班級中定義這個字段時，爲什麼你要使用$ this->這個國家。如果您刪除$ this或定義字段會發生什麼？ –
我試圖刪除$這仍然是一樣的..我無法弄清楚。 – Ken
除非先前已聲明，否則不能指定給某個字段。將'private $ countries'行添加到您的班級中。我不認爲這會解決你的錯誤，但是誰知道:) –
