我想向我网站上的多个用户发送通知。他们的 ID 在数组 （$userinput） 中。$userinput在每个值的开头保存由逗号分隔的成员 ID（如"7,1,2,3"）。
我想运行这样的查询：
$sqlnot = "INSERT INTO lb_notif (to_id, time_sent, from_id, subject, message) VALUES ('$user_id_here', now(), '$logOptions_id', '$title', 'You have been invited to this group chat: <a href=profilechat.php?id=$logOptions_id&chat=$act_item_id>Click here to enter</a>.') ";
我如何才能将其发送给所有这些成员？
您需要循环数组并动态构建查询：
$sqlnot = "INSERT INTO lb_notif (to_id, time_sent, from_id, subject, message) VALUES";
$parts = array();
foreach($userinput as $user) {
$parts[] = "('$user', now(), '$logOptions_id', '$title', 'You have been invited to this group chat: <a href=profilechat.php?id=$logOptions_id&chat=$act_item_id>Click here to enter</a>.') ";
}
$sqlnot .= implode(',', $parts);
$id_string = "7,1,2,3";
$user_ids = explode(",", $id_string);
foreach($user_ids as $user_id_here){
$sqlnot = "INSERT INTO lb_notif (to_id, time_sent, from_id, subject, message) VALUES ('$user_id_here', now(), '$logOptions_id', '$title', 'You have been invited to this group chat: <a href=profilechat.php?id=$logOptions_id&chat=$act_item_id>Click here to enter</a>.') ";
// execute your query here
}
如果要
多次插入，则foreach是一个超级按钮选项，如下所示：
$ids = explode(",", $userinput);
foreach($ids as $user_id){
$sqlnot = "INSERT INTO lb_notif (to_id, time_sent, from_id, subject, message) VALUES ('$user_id_here', now(), '$logOptions_id', '$title', 'You have been invited to this group chat: <a href=profilechat.php?id=$logOptions_id&chat=$act_item_id>Click here to enter</a>.') ";
}
