一旦提交表单，表单就不会被验证，并且模式会因为页面刷新而关闭。我希望模式在提交表单时保持打开状态。 php 如下:
<?php
$nameerror = $studentiderror = $emailerror = "";
$subject = "Thank you for voting!";
$body = "Dear $_POST["name"], Thank you for voting for this sustainable initiative. Your vote is appreciated! Lots of love from the Beefarm Committee of the Erasmus Sustainability Hub!";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if ($_POST["submit"]) {
if (empty(($_POST["name"])) {
$nameerror = "Please enter your name" }
if (empty($_POST["studentID"])) {
$studentiderror .= "Please enter your student ID";
} else {
$result = "Thank you for voting!";
mail($_POST["email"], $subject, $body);
}
};
}
这是模态的 HTML，PHP 嵌入在 HTML 中，提交后验证表单时应显示错误消息:
<div class="container">
<div class="modal" id="myModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button class="close" data-dismiss="modal">x</button>
<h4 class="modal-title">Vote!</h4>
</div>
<div class="modal-body">
<p>
Let us know what you think! <br/>
By voting, you as a student can have a say in the realisation of this project. Even if you vote
against having bees on campus, your vote is appreciated! <br/>
Thank you!
</p>
<form id="votingscreen" method="POST">
<?php echo $result ?>
<div class="form-group">
<label for="name">Name</label>
<?php echo $nameerror ?>
<input style="width: 180px" type="text" id="name" name="name" class="form-control" placeholder="Your name">
</div>
<div class="form-group">
<label for="studentID">Student ID</label>
<?php echo $studentiderror ?>
<input style="width: 180px" type="text" id="studentID" name="studentID" class="form-control" placeholder="123456AB">
</div>
<div class="form-group">
<label for="email">E-mail</label>
<?php echo $emailerror ?>
<input style="width: 180px" type="email" id="email" name="email" class="form-control" placeholder="E-mail">
</div>
<hr />
<div class="radiogroup">
<label for="radiogroup"> Bees on campus? </label>
<label class="radio-inline">
<input type="radio" name="vote" id="voteyesradio" value="yes" checked>
Yes
</label>
<label class="radio-inline">
<input type="radio" name="vote" id="votenoradio" value="no">
No
</label>
</div>
<div class="form-group">
<input type="submit" name="submit" id="submitButton" class="btn btn-success btn-block" value="Vote!"/>
</div>
</form>
</div>
</div>
</div>
</div>
</div>
这是 JS 代码:
$(".contentContainer").css("min-height", $(window).height());
$("#image").css("min-height", $("#beeweek").height());
$(document).ready(function () {
$("#submitButton").click(function () {
$("#myModal").modal('show');
})
});
$(".video-container").css("min-height", $(window).height());

如果您不希望刷新页面，您应该使用 Ajax 提交表单，此链接应该可以帮助您，jQuery Ajax POST example with PHP
