将文本从php文件发送到html中的变量

Question

Can i send text from a php file into a variable in an html file? 我可以将文本从php文件发送到html文件的变量中吗？ I have an if statement in my php, that checks if a field is empty. 我的PHP中有一个if语句，用于检查字段是否为空。 If it is empty then i want to send to my html file a text saying 'please fill the field' and put it in a label in my html. 如果为空，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html的标签中。 Is there a way for that? 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";
}

?>

Answer 1

Yes, you'll just echo out the HTML like any other ordinary echo. 是的，您将像其他任何普通回声一样回显HTML。

echo '<label>Test</label>';

It can be embed right in your HTML (as long it's a PHP file, obviously) like this: 可以将其直接嵌入HTML中（显然，只要是PHP文件即可），如下所示：

<!DOCTYPE html>
<html>
    <head>
        <title>Test</title>
    </head>

    <body>
        <?php echo $something === true ? '<label>test</label>' : ''; ?>
    </body>
</html>
