我正在尝试通过电子邮件发送学生列表。 学生列表数据已保存在数据库中。
所以我根据merchTxnRef
然后从表/记录中检索该行并将其分配给变量..
然后将变量连接到邮件正文并尝试发送它们。
但我的<tr></tr>
在邮件中是空的。我知道这是因为我将foreach循环变量错误地保存到此变量$studentList
如何将foreach循环值保存在变量中并将其打印到循环外
以下是我正在尝试的代码。
$sqlListst = "SELECT * FROM tck_paymentStudents WHERE merchTxnRef LIKE $merchTxnRef'";
$resultListst = $wpdb->get_results($sql) or die(mysql_error());
foreach( $resultListst as $resultsListst ) {
$merchTxnRef = $resultsListst->merchTxnRef;
$sudentname = $resultsListst->sudentname;
$admissionnmbr = $resultsListst->admissionnmbr;
$purpose = $resultsListst->purpose;
$amount = $resultsListst->amount;
$grade = $resultsListst->grade;
$studentList = '<tr><td>'.$merchTxnRef.'</td><td>'.$sudentname.'</td><td>'.$admissionnmbr.'</td><td>'.$purpose.'</td><td>'.$amount.'</td><td>'.$grade.'</td></tr>';
}
$mail_body_guest_full = '<table>';
$mail_body_guest_full .= $studentList;
$mail_body_guest_full .= '</table>';
$email = 'myemail@examplsite.com';
$subject = 'Student List';
$from_guest = 'guestemail@gmail.com';
$headers_guest = array('From: My Site <'.$from_guest.'>');
$mail_sent_guest = wp_mail( $email, $subject, $mail_body_guest_full, $headers_guest );
答案 0 :(得分:1)
1)$studentList.=
附近缺少连接点
2)LIKE '".$merchTxnRef."'";
附近的查询中缺少单引号
3)根据您的评论$wpdb->get_results($sqlListst)
$sqlListst = "SELECT * FROM tck_paymentStudents WHERE merchTxnRef LIKE '".$merchTxnRef."'";
$resultListst = $wpdb->get_results($sqlListst) or die(mysql_error());
foreach( $resultListst as $resultsListst )
{
$merchTxnRef = $resultsListst->merchTxnRef;
$sudentname = $resultsListst->sudentname;
$admissionnmbr = $resultsListst->admissionnmbr;
$purpose = $resultsListst->purpose;
$amount = $resultsListst->amount;
$grade = $resultsListst->grade;
$studentList.= '<tr><td>'.$merchTxnRef.'</td><td>'.$sudentname.'</td><td>'.$admissionnmbr.'</td><td>'.$purpose.'</td><td>'.$amount.'</td><td>'.$grade.'</td></tr>';
}
$mail_body_guest_full = '<table><tbody>';
$mail_body_guest_full .= $studentList;
$mail_body_guest_full .= '</tbody></table>';
$email = 'myemail@examplsite.com';
$subject = 'Student List';
$from_guest = 'guestemail@gmail.com';
$headers_guest = array('From: My Site <'.$from_guest.'>');
$mail_sent_guest = wp_mail( $email, $subject, $mail_body_guest_full, $headers_guest );
