死与回声的PHP错误信息给我的问题

Question

am using recaptcha. orignally the error was used using 'die' but this took my to another page and gave me an error.

because i want it to show in the page, i used print.

The problem with echo is the function doesnt work:

this is my site :

http://www.the-big-bbq.co.uk/invitation.php#prettyPhoto

my code:

<?php
if (isset($_POST['submit'])){
require_once('recaptchalib.php');
$privatekey = "6LeBwPcSAAAAAL2pNriaDSi8ca0Yb1qewzfDMYyY";
$resp = recaptcha_check_answer ($privatekey,
                            $_SERVER["REMOTE_ADDR"],
                            $_POST["recaptcha_challenge_field"],
                            $_POST["recaptcha_response_field"]);

if (!$resp->is_valid) {
// What happens when the CAPTCHA was entered incorrectly
echo $myDiv1;   

} else {
// Your code here to handle a successful verification
}
}
?>

This is the html

        <p class="myDiv1">Please enter the text shown</p>

originally it was using this:

     die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." .
     "(reCAPTCHA said: " . $resp->error . ")");

how can i use echo, but show it only when they have entered wrong details.

Answer 1

All you need to do is output what you want in this situation with one or many echo statements.

I had no idea what $myDiv1 was so I just did it manually.

Like so:-

<?php
if (isset($_POST['submit'])){
    require_once('recaptchalib.php');
    $privatekey = "6LeBwPcSAAAAAL2pNriaDSi8ca0Yb1qewzfDMYyY";
    $resp = recaptcha_check_answer ($privatekey,
                        $_SERVER["REMOTE_ADDR"],
                        $_POST["recaptcha_challenge_field"],
                        $_POST["recaptcha_response_field"]);

    if (!$resp->is_valid) {
        // What happens when the CAPTCHA was entered incorrectly
        echo '<p class="myDiv1">';
        echo "The reCAPTCHA wasn't entered correctly. Go back and try it again.";
        echo ' (reCAPTCHA said: ' . $resp->error . ')';
        echo '</p>'; 

    } else {
        // Your code here to handle a successful verification
    }
}
?>
