我正在开发一个网站,它使用javascript来处理许多函数和基于PHP的Captcha代码来验证表单字段。
效果很好,但如果没有填写任何字段,表单将会提交。
我需要两个表单字段中的一个[' email'或者'电话']填写,但两者都不能留空。
当验证码字段留空或填写错误时,错误消息可能与抛出的错误消息相同。
我是PHP代码的新手,无法弄清楚如何调用该函数。
功能代码是:
<?php
if(isset($_POST['send'])){
$emailFrom = "clientemail.com";
$emailTo = "clientemail.com";
$subject = "Contact Form Submission";
$first_name = strip_tags($_POST['first_name']);
$last_name = strip_tags($_POST['last_name']);
$email = strip_tags($_POST['email']);
$phone = strip_tags($_POST['phone']);
$message = strip_tags(stripslashes($_POST['message']));
$body .= "First Name: ".$first_name."\n";
$body .= "Last Name: ".$last_name."\n";
$body .= "Email: ".$email."\n";
$body .= "Phone: ".$phone."\n";
$body .= "Comments: ".$message."\n";
$headers = "From: ".$emailFrom."\n";
$headers .= "Reply-To:".$email."\n";
if($_SESSION['security_code'] == $_POST['security_code']){
$success = mail($emailTo, $subject, $body, $headers);
if ($success){
echo '<p class="yay">Your e–mail has been sent.</p>';
}
} else {
echo '<p class="oops">Something went wrong. Hit the back button and try again.</p>';
}
} else {
?>
表单字段:
<form action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>" method="post" id="contact" name="contact">
<fieldset>
<label for="name"><span style="color:#bf252b;">*</span>First Name</label>
<input type="text" id="first_name" name="first_name" minlength="2"/>
<label for="name">Last Name</label>
<input type="text" id="last_name" name="last_name" minlength="2"/>
<label for="email"><span style="color:#bf252b;">*</span> Email</label>
<input type="text" id="email" name="email" />
<label for="phone"><span style="color:#bf252b;">*</span> Phone</label>
<input type="text" id="phone" name="phone" />
<label for="message">Message</label><div style="clear:both;"></div>
<textarea id="message" name="message" cols="40" rows="10" ></textarea>
<img src="../captcha.php" id="captcha" alt="captcha" style="padding:25px 0px 20px 0px;" />
<label for="security_code">Enter captcha</label>
<input type="text" id="security_code" name="security_code" autocomplete="off" class="required"/>
<button type="submit" id="send" name="send" style="margin:0px 0px 10px 12px;">Send!</button>
</fieldset>
</form>
<?php } ?>
有一个用于运行验证码的.php文档,但我认为有一个简单的解决方案是正确的。现有代码中的一些额外代码可以解决我的问题?如果我能帮忙的话,我真的想避免使用javascript和插件。

试试这个,
if($_SESSION['security_code'] == $_POST['security_code'] && (!empty($email) || !empty($phone))) {
而不是
if ($_SESSION['security_code'] == $_POST['security_code']) {
这不是验证表单的便捷方法,但我希望这会有所帮助。

将required
属性添加到您需要的字段中。

Notice: Undefined variable: body in /../sendform.php on line 14
那样做:
$body = "First Name: ".$first_name."\n";
$body .= "Last Name: ".$last_name."\n";
$body .= "Email: ".$email."\n";
$body .= "Phone: ".$phone."\n";
$body .= "Comments: ".$message."\n";
if(($_SESSION['security_code'] == $_POST['security_code']) AND
(!empty($email) OR !empty($phone)) ) {
换句话说:
