php - 页面刷新后自动激活Bootstrap模式

Question

我试图在页面刷新后自动响应 Bootstrap 模式以显示反馈消息，但是我当前的代码没有重新加载模式，也没有显示错误消息。页面本身正在重新加载，提交到表单的数据正在数据库中正确更新(或不提交，取决于是否有错误!)，但页面刷新后模式不会重新打开。

我当前的代码如下:

//Clean
$submit = clean_string($_POST['submit']);

$id = $profile_info['id'];
$db_password = $profile_info['password'];


//Update account details
if ($submit == 'Save changes') {
    $first_name = clean_string($_POST['first-name']);
    $last_name = clean_string($_POST['last-name']);
    $email = clean_string($_POST['email']);
    $current_password = clean_string($_POST['current-password']);
    $new_password = clean_string($_POST['new-password']);
    $confirm_new_password = clean_string($_POST['confirm-new-password']);

    //Output variables
    $updateProfile_bad_message = '';
    $updateProfile_good_message = '';

    if ($db_server) {
        if (!empty($first_name)) {
            if ($first_name = clean_string($first_name)) {
                $query = "UPDATE users SET first_name = '$first_name' WHERE id = '$id'";
                mysql_query($query) or die("Insert failed. " . mysql_error() . "<br />" . $query);
                $updateProfile_good_message = '<div class="alert alert-success">Changes saved</div>';
            } else {
                $updateProfile_bad_message = '<div class="alert alert-error">Sorry, something\'s gone wrong! Please try again later.</div>';?>
                <script type="text/javascript">
                    $('a.account-update').trigger('click');
                </script><?php
            }
        } 
        if (!empty($last_name)) {
            if ($last_name = clean_string($last_name)) {
                $query = "UPDATE users SET last_name = '$last_name' WHERE id = '$id'";
                mysql_query($query) or die("Insert failed. " . mysql_error() . "<br />" . $query);
                $updateProfile_good_message = '<div class="alert alert-success">Changes saved</div>';
            } else {
                $updateProfile_bad_message = '<div class="alert alert-error">Sorry, something\'s gone wrong! Please try again later.</div>';?>

            }
        } 
        if (!empty($email)) {
            if ($email = clean_string($email)) {
                $taken = mysql_query("SELECT email FROM users WHERE email='$email'");
                $count = mysql_num_rows($taken);
                if ($count > 0) {
                    $updateProfile_bad_message = '<div class="alert alert-error">The email you have entered is already associated with a Screening account. Please choose another.</div>';

更新

要添加更多信息，我认为模式和错误消息没有出现的原因是，为了使更新的信息显示在页面上，必须在重新显示模式之前重新加载页面本身。我的假设是，在页面重新加载时，重新加载之前发生的任何事情都几乎被消除，因此为什么当手动单击“更新配置文件”按钮重新打开时没有显示任何信息，例如警报消息页面重新加载后的模式。这是应该发生的事情:

• 如果有错误，只显示错误反馈信息，无需重新加载页面
• 如果没有错误，请重新加载页面以显示更新的信息，并重新显示模式以确认更改已成功保存。

Answer 1

根据 Bootstrap 文档，手动显示模式的适当方法是使用 show 参数，如下所示:

$(function () {
  $('#myModal').modal('show');
});
