Question

我正在一个单页网站上工作，它有两种不同的形式可以填写。当我填写其中一个表格时，我会收到一封电子邮件，但它没有电话号码（其中一个表格）。我的第二种形式我不能将主题作为电子邮件的主题，并在$ header中包含该名称。我没有把两个表格放在一起，而是假设两者都是一样的。我也在使用recaptcha，但它不能正常工作，但我会在另一个问题上提交。

表格1

<form action="post.php" method="post">
    <div class="leftSide">
        <input type="text" name="name" id="name" required="true" placeholder="Name">
        <input type="text" name="email" id="email" required="true" placeholder="Email">
        <input type="text" name="subject" id="subject" required="true" placeholder="Subject">

    <div class="rightSide">
        <textarea name="message" id="message" required="true" placeholder="Message"></textarea> 
    </div>          
    <input type="submit" value="Send Message" id="contactBtn">

Answer 1

替换此部分：

if(strlen(!$subject) < 5) {
  $errors[] = "You must enter a subject.";
} else {
  $errors[] = "You must enter a subject.";
}

为：

if(strlen($subject) < 5) {
  $errors[] = "Subject must be at least 5 characters.";
} elseif(!$subject) {
  $errors[] = "You must enter a subject.";
}
