成功插入数据后如何在引导成功警报中显示成功消息

Question

如何在插入数据库后以绿色显示一段时间的警报消息或在右侧有一个关闭按钮。

    <?php
include('../session.php');
$from="$session_id";
$to=mysql_real_escape_string($_POST["to"]);
$subject=mysql_real_escape_string($_POST["ssubject"]);
$message=mysql_real_escape_string($_POST["smessage"]);
if($from==$to){
    echo "Message could not be sent";
    die();
}
if($from>1 && $to>1){
    echo "Message could not be sent";
    die();
}



//echo $to.$message;
//validate before insert
if(strlen($subject)>50){
    echo "Subject was too long";
    die();
}
if(strlen($message)>150){
    echo "Message was too long";
    die();
}
include('../dbsource.php');
$mysqli=connect();

if(insert($mysqli,$from,$to,$subject,$message)>0)

{
   // echo "<script type=\"text/javascript\">".
       // "alert('Message was successfully sent');".
        //"</script>";
   $result='successfully sent message';


    }
else
{
    echo "<script type=\"text/javascript\">".
        "alert('there was error sending message.. please try it later');".
        "</script>";

}
?>


<?php
function insert($mysqli,$from,$to,$subject,$message){   
    $mdate=date('Y-m-d');
    $mtime=date('H:i:s');   
    $query = "INSERT INTO messages (mfrom,mto,subject,message,mdate,mtime)".
        "VALUES ('$from','$to','$subject','$message','$mdate','$mtime')";
    if($mysqli->query($query)>0)
        return($mysqli->insert_id);
    else
        return 0;
}

php 页面的代码如下：

<div class="alert alert-success fade in">
    <a href="#" class="close" data-dismiss="alert">&times;</a>
    <strong>Success!</strong><? $result ?>
</div>

如何在引导提示框中显示成功消息？

我知道这个答案很晚了，但我想也许像我这样的人想要一个答案

我有 2 个函数要处理（插入数据库）

<?php
$nameErr = "";
$familyErr = "";
$codeErr = "";
$passErr = "";
function create_student($name, $family, $code, $pass)
{
    global $conn, $tbl_student;
    $sql = "INSERT INTO $tbl_student (students_code, students_pass, students_name, students_family) VALUES (? ,? ,?,?)";
    $create_student = $conn->prepare($sql);
    $create_student->bindParam(1, $code);
    $create_student->bindParam(2, $pass);
    $create_student->bindParam(3, $name);
    $create_student->bindParam(4, $family);
    $create_student->execute();
    $student=$name." ".$family;
    if($create_student->rowCount()>=1){
        $result_create_student=['1',$student];
    }
    else
    {
        $result_create_student=['0',"error in inserting"];
    }
    return $result_create_student;
}
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
if (isset($_POST['submit-create-student']) && ($_SERVER['REQUEST_METHOD'] == 'POST')) {
    if (empty($_POST["student-name"])) {
        $nameErr = "you must insert name.";
    } else {
        $name = sanitize_func($_POST["student-name"]);
    }
    if (empty($_POST["student-family"])) {
        $familyErr = "you must insert family.";
    } else {
        $family = sanitize_func($_POST["student-family"]);
    }
    if (empty($_POST["student-code"])) {
        $codeErr = "you must insert code.";
    } else {
        $code = sanitize_func($_POST["student-code"]);
    }
    if (empty($_POST["student-pass"])) {
        $passErr = "you must insert pass.";
    } else {
        $pass = sanitize_func($_POST["student-pass"]);
    }
    if (($nameErr == "") && ($familyErr == "") && ($codeErr == "") && ($passErr == "")) {
        $result_create_student=create_student($name, $family, $code,$pass);
    }
}
?>

我们想要在我的代码中显示结果的部分我喜欢这样

<div class="px-2 text-right schms-font-size-12 mb-1">
                                            <?php if (isset($result_create_student) && $result_create_student != "") : ?>
                                                <?php if ($result_create_student[0] == '1'): ?>
                                                    <div class="alert alert-success alert-dismissible text-right">
                                                        <button type="button" class="close" data-dismiss="alert">&times;
                                                        </button>
                                                        <strong class="pl-1">success!</strong>
                                                        one student with name
                                                        <span  class="text-justify"><?php echo $result_create_student[1]; ?></span>
                                                       inserting in databse.
                                                    </div>
                                                <?php elseif ($result_create_student[0] == '0'): ?>
                                                    <div class="alert alert-danger alert-dismissible text-right">
                                                        <button type="button" class="close" data-dismiss="alert">&times;
                                                        </button>
                                                        <strong class="pl-1">error!</strong>
                                                        <span  class="text-justify"><?php echo $result_create_student[1]; ?></span>
                                                    </div>
                                                <?php endif; ?>
                                            <?php endif; ?>
