从获取$_POST值向定制表中插入数据

我使用print_r()

  Array ( [0] => test [1] => [email protected] [2] => 1.00 [3] =>    21:16:36 Jun 04, 2015 PDT [4] => 9DS7592P74GMN )

现在我想在自定义表中添加此数据，但我不能。

这是我的密码

  if(!empty($_POST))
  {
    $player_name = $_POST[\'first_name\'];
    $payer_email = $_POST[\'payer_email\'];
    $payment_gross = $_POST[\'payment_gross\'];
    $payment_date = $_POST[\'payment_date\'];
    $payer_id = $_POST[\'payer_id\'];

    $paypal_str = array($player_name, $payer_email, $payment_gross, $payment_date, $payer_id);
 print_r($paypal_str);

global $wpdb;
$wpdb->insert(
    \'paypal\',
     array(
        \'name\' =>  $paypal_str[0],
        \'email\' => $paypal_str[1],
        \'amount\' => $paypal_str[2],
        \'player_id\' => $paypal_str[3],
        \'date\' => $paypal_str[4],
    )
);
}

if(!empty($_POST)) { $player_name = $_POST[\'first_name\']; $payer_email = $_POST[\'payer_email\']; $payment_gross = $_POST[\'payment_gross\']; $payment_date = $_POST[\'payment_date\']; $payer_id = $_POST[\'payer_id\']; $paypal_str = array($player_name, $payer_email, $payment_gross, $payment_date, $payer_id); print_r($paypal_str); global $wpdb; $wpdb->insert( \'paypal\', array( \'name\' => $paypal_str[0], \'email\' => $paypal_str[1], \'amount\' => $paypal_str[2], \'player_id\' => $paypal_str[3], \'date\' => $paypal_str[4] ) ); }

if(!empty($_POST)){ global $wpdb; $player_name = $_POST[\'first_name\']; $payer_email = $_POST[\'payer_email\']; $payment_gross = $_POST[\'payment_gross\']; $payment_date = $_POST[\'payment_date\']; $payer_id = $_POST[\'payer_id\']; $wpdb->insert( \'wp_paypal\', array( \'name\' => $player_name, \'player_id\' =>$payer_id, \'email\' => $payer_email, \'amount\' => $payment_gross, \'payment_date\' => $payment_date ), array( \'%s\', \'%s\', \'%s\', \'%s\', ) ); }

meaning of (array)function()

我看到了这段代码，其中包含了我以前从未见过的部分代码。在此场景中，（数组）的行为是什么？到目前为止，我知道用php创建数组的方法，但从未见过这种情况。// $this->settings = array_merge( $this->settings_defaults(), (array) get_option( $this->settings_slug, $this->settings_defaults() ) ); // &#x
