我试图在页面刷新后自动响应一个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态,也没有显示错误消息。页面本身正在重新加载,提交到表单的数据在数据库中正确更新(或者不提交,具体取决于是否存在错误!),但在刷新页面后模式不会重新打开。
我目前的代码如下:
//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>';

}
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,我认为模态和错误消息未出现的原因是,为了在页面上显示更新的信息,必须在重新显示模式之前重新加载页面本身。我假设,在页面重新加载时,重新加载之前发生的任何事情都已被彻底根除,因此当手动单击“更新配置文件”按钮重新打开时,为什么没有显示警报消息等信息页面重新加载后的模态。这是应该发生的事情:
答案 0 :(得分:1)
根据Bootstrap文档,手动显示模态的适当方法是使用show
参数,如下所示:
$(function () {
$('#myModal').modal('show');
});

的更多信息通过将代码包装在jQuery构造函数中,代码将在DOM准备好时执行。
