我之前有一些Python编程经验,但被要求为某人构建一个网页,所以我尝试使用Bootstrap框架、HTML和PHP(边学边做)构建了一个基本页面。
除了订阅表单没有验证以外,一切都完美无缺。因此,我认为最好实现一些验证,但是该表单似乎没有反应,并且即使表单完全为空,脚本仍然会完成并发送电子邮件。
这是否是因为表单在“模态”中?我对此仍然很生疏,如果这已经涉及到了,我向您道歉,但我找不到能帮助我的答案。
我附上了模态表单的HTML和PHP代码。
现在,我的表单中每个输入都有一个专门用于错误的字段:

我非常希望能得到任何帮助!
编辑:
以防有人想知道我最终是如何到达需要的位置的:@leepowers的答案是朝着正确方向迈出的巨大一步,这让我能够检查是否有任何错误并在有错误时阻止发送电子邮件,然后我学习了“会话”,我以非常混乱的方式将错误存储在会话中,以便在返回表单时重用它们。
// Gather all errors into an array
$errors = array($fromErr, $firstErr, $lastErr);
// Remove any empty error messages from the array
$errors = array_filter($errors);
// An array with more than zero elements evaluates `true` in a boolean context
if ($errors) {
$_SESSION["fromErr"] = $fromErr;
$_SESSION["firstErr"] = $firstErr;
$_SESSION["lastErr"] = $lastErr;
die(header('Location: ./index.html#Subscribe'));
} else { // send email
在我的html页面中,我有一些JS来将“重定向”指向一个模态框:
<script>
$(document).ready(function() {
if(window.location.href.indexOf('#Thanks') != -1) {
$('#Thanks').modal('show');
} else if(window.location.href.indexOf('#Subscribe') != -1) {
$('#Subscribe').modal('show');
}
});
</script>
现在,我的表单中每个输入都有一个专门用于错误的字段:
<div class="input-group" style="margin-bottom: 5px;">
<span class="input-group-addon" id="email">Email</span>
<input type="email" class="form-control" placeholder="something@example.co.uk" name="email" aria-describedby="Email">
<span class="input-group-addon error" style="color: red">* <?php echo $_SESSION["fromErr"];?></span>
谢谢大家的帮助。这段话与IT技术无关。
$lastErr
或者$firstErr
做任何处理,所以邮件会直接发送。尝试在mail($to,$subject,$message,$headers);
之前添加一个条件,要求这两个变量都为空。 - chris85if (count($errors) > 0) { handleError(); } else { doSomething(); }
。 - Miketest_input()
函数具体是做什么的? - Mikemagic_quotes_gpc
设置为true
,否则你应该删除stripslashes()
