25: if (check_url($_POST["url"]) == "http"){

28: else if (check_url($_POST["url"]) == "nohttp"){

comments working continue with and without captcha include errormessage.

yes i have see this and correct this, but don't work...

your code is other as th code from above. your code not parsed, i use this code in comment.php from default theme:



<?php plogger_require_captcha(); ?>
<p>
<img src="<?php echo $config["gallery_url"].'plog-includes/plog-captcha.php'; ?>" alt="CAPTCHA Image" id="captcha-image" />
</p>
<p>
<input type="text" name="captcha" id="captcha" value="" size="28" tabindex="3" />
<label for="url"><?php echo plog_tr('Gib hier die Zeichen aus dem kleinen Bild obendrüber ein.'); ?></label>

every time when i reload site after comment, added comment also every time - form must this intercept.

ps: sorry for my english...is a rest of school english for 30 years ago and lexirom ;-)

I haven't had time to work on it right at the moment, PieperLy. I'll try to make it a priority, but this week looks to be pretty slammed.

hello,

i change the code in plog-includes/plog-comment.php...and now it works

the lines with

first get all the neccessary variables
if (check_url($_POST["url"]) == "http"){
$url = $_POST["url"];// }
else if (check_url($_POST["url"]) == "nohttp"){
$url = "http://".$_POST["url"];
}
else{// $url = "";
}don't work...
.
.
.
change plog-comment.php to:
<?php
// this is our comment script, it simply writes the comment information
// to our database and links it to the picture using the pictures id

if (basename($_SERVER['PHP_SELF']) == basename( __FILE__ )) {
// ignorance is bliss
exit();
}

// Loosly validate url string format without actually checking the link (cause that takes time)
function check_url($url) {
if (preg_match('#^http\\:\\/\\/[a-z0-9\-]+\.([a-z0-9\-]+\.)?[a-z]+#i', $url)) {
return "http";
}
else if (preg_match('#^[a-z0-9\-]+\.([a-z0-9\-]+\.)?[a-z]+#i', $url)) {
return "nohttp";
}
else {
return "badurl";
}
}

// first get all the neccessary variables

// if (check_url($_POST["url"]) == "http"){
// $url = $_POST["url"];
// }
// else if (check_url($_POST["url"]) == "nohttp"){
// $url = "http://".$_POST["url"];
// }
// else{
// $url = "";
// }

$parent_id = intval($_POST["parent"]);

// If the captcha is required, check it here

if (($_POST['captcha'] != $_SESSION['captcha']) || !$_POST['captcha']) {
$_SESSION["comment_post_error"] = "CAPTCHA check failed!";
return;
}

$rv = add_comment($parent_id,$_POST["author"],$_POST["email"],$_POST["comment"]);

// redirect back to picture page
if (isset($rv['errors'])) {
// will this work?
$_SESSION['comment_post_error'] = $rv['errors'];
}
else if ($config['comments_moderate']) {
$_SESSION['comment_moderated'] = 1;
}

?>

when every come an errormessage with bad variable "url", i delete the call of the variable in this line

now i have two still problems:

1. how can i reload the captcha image without lose the form inputs?

2. how can i use a different errormessage for captchafield to formfields?

reagards from germany, have a nice weekend :-)
