我可以将php文件中的文本发送到html文件中的变量吗?我的php中有一个if语句,用于检查字段是否为空。如果它是空的,那么我想向我的html文件发送一个文本,说“请填写字段”并将其放在我的HTML中的标签中。有办法吗?
<?php
$name = $_REQUEST['author'];
$from = $_REQUEST['email'];
$subj = $_REQUEST['sub'];
$message = $_REQUEST['msg'];
$subject = $subj;
$body = $message;
$headers .= "From: ".$from;
$to = "mail@mail.com";
if ($name = ''){
HERE i want to send a text to a variable named 'reason' in my html in case $name is empty.
}
if(mail($to,$subject,$body,$headers)) {
header( "Location: http://www.mysite.com/contactForm-english" );
} else {
echo "There was a problem sending the mail. Check your code and make sure that the e-mail address ".$to." is valid";
}
?>

是的,你就像其他任何普通的回声一样回应HTML。
echo '<label>Test</label>';
它可以嵌入你的HTML中(只要它是一个PHP文件,显然)就像这样:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
</head>
<body>
<?php echo $something === true ? '<label>test</label>' : ''; ?>
</body>
</html>

<?php echo $variable; ?>
