Question

我需要在提交html表单后添加成功消息。我尝试了一些我在网上找到的例子，甚至尝试自己编写，但是他们要么不工作，要么保持表格不提交。我仍然是PHP的新手，所以任何帮助都表示赞赏。只要信息出现，我就不会对信息的显示方式过于挑剔。我怎样才能做到这一点？感谢。

<?php
try {
    $dbh = new pdo('sqlsrv:Server=xxxx,1433;database=xxxx', 'xxxx', 'xxxx');
    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $tsql = "INSERT INTO testtable (date, position, referral) VALUES (?, ?, ?)";
    $stmt = $dbh->prepare($tsql);
    $stmt->execute(array(
        $_REQUEST['date'],
        $_REQUEST['position'],
        $_REQUEST['referral']
    ));

    /* The following call to closeCursor() may be required by some drivers */
    $stmt->closeCursor();

    // and now we're done; close it
    $dbh = null;
}
catch (PDOException $e) {
    die("PDO Exception: " . $e->getMessage());
}
catch (Exception $e) {
    die("Exception: " . $e->getMessage());
}
?>

Answer 1

您可以设置会话变量，然后在视图文件中检索并清除它。

Answer 2

您可以在echo "Success!"行之后$dbh = null;。{/ p>

如果try {}和catch（）之间发生错误（异常）。它将被catch（）行捕获，这将导致显示die()'s之一。如果您到达$dbh = null行，则表示您的查询已成功。

Answer 3

您可以通过编写像这样的代码来检查您的HTML表单是否已提交。

<?php
    if(isset($_POST['submit'])) {
        echo "Form Submitted";
    } 
?>

HTML形式如下：

<form >
    <input class="button" type="submit" name="submit" value="submit"/>    
</form>

这只是你想要设置的一个例子。

HTML：

<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="ajax-example.js"></script>
</head>
<body>
<h1>ajax form simple example</h1>
<form id="foo">
    <div class="message"></div>
    <label for="bar">A bar</label>
    <input id="bar" name="bar" type="text" value="" />
    <input type="submit" value="Send" />
</form>
</body>

Javascript（ajax-example.js）：

// bind to the submit event of our form
$("#foo").submit(function(event){

    // fire off the request to /form.php
    $.ajax({
        url: "/form.php",
        type: "post",
        data: serializedData,
            error: function(){
               alert('error');
            },
            beforeSend: function() {
               //here you can put do thing cool like a $('element').html('loading-image.gif')
            },
            success : function(data){
                $('.message').html('success!! '+data);
            }
    });
});

PHP（form.php）

<?php
try {
    $dbh = new pdo('sqlsrv:Server=xxxx,1433;database=xxxx', 'xxxx', 'xxxx');
    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $tsql = "INSERT INTO testtable (date, position, referral) VALUES (?, ?, ?)";
    $stmt = $dbh->prepare($tsql);
    $stmt->execute(array(
        $_REQUEST['date'],
        $_REQUEST['position'],
        $_REQUEST['referral']
    ));

    /* The following call to closeCursor() may be required by some drivers */
    $stmt->closeCursor();

    // and now we're done; close it
    $dbh = null;

   return 'PUT SOMETHING HERE IF YOU WANT';
}
catch (PDOException $e) {
    die("PDO Exception: " . $e->getMessage());
}
catch (Exception $e) {
    die("Exception: " . $e->getMessage());
}
?>
