nice, ill have to test it out later in the week...

thanks for the update!

[sentinel]

thx alot chaney
schedule is full until weekend. after that i'll try to have a look at the "robot problem" (which still might exist even with pp1.6)

[Puffin]

Thank you! For me this is the only thing that really works. No I am able to upgrade to 1.6 :)

[marc]

thanks for the update of your nice addon. Same situation like puffin: for me the only thing that really works.

[terje]

Thank you QmQ!

This is THE ONLY way to protect against spam in PixelPost.
Deleted over 500,000 spams today.. Time to put an stop to it.

[rainman]

I have a problem with this addon. I'm using the default PP 1.6.0 horizon theme and sometimes my visitors cannot leave a comment although they input the right captcha code. I tested this by myself a few times and I'm able to post a comment only after two or three (code) refreshes. Did someone have this issue?
Any help would be appreciated :)

[dreampaper]

hi,

i just tried installing captcha, i followed all the steps in the readme-file... but now my homepage is blank? (www.dykesandthecity.com)

any ideas what caused this and what I can do about it?

tnx!

[Dkozikowski]

Login to the admin panel and visit your site, it will still be blank but add the following to the end of your URI, ?errors

so, the full URI would look like,

http://www.snapping.dykesandthecity.com/index.php?errors


This should tell you what is causing the blank screen.

[fredxeric]

I just have it installed on my pixelpost blog and it's working fine 4 me...

[jdleung]

I remember the team had said it has a strong security on anti-spam,do we need this addon on pp1.6?

[JETC]

I still got spams without captcha on 1.6 so I just still implemented it. I'm probably going to recode the comments and use AJAX or something instead of captcha to prevent spam. I'll have to see but captcha has done wonders. Completely zero spam when it's in effect so I'm not complaining at all.

[weberknecht]

thank u so much :) its works beautyfull :)

[jesperj]

I've installed this hack and it works fine with my default langugage (english) image_template.html but on my image_se_template.html, the <CAPTCHA> tag simply isn't replaced. I've been desperately trying various things to hack the code to work for me but since I suck at such things, I have to give up. I reuploaded the default addon index.php on my site for now.

I found that if I replaced this section in the code:

else

{

// we use our special designed language templates.

if( isset($_GET['x'])&&file_exists( "templates/".$cfgrow['template']."/".$_GET['x']."_".$language_abr."_template.html"))

{

if (eregi("[.]",$_GET['x']))

die("Come on! forget about it...");

$tpl = file_get_contents("templates/".$cfgrow['template']."/".$_GET['x']."_".$language_abr."_template.html");

//next 1 line for CAPTCHA hack --- insert by Chaney SUN

$tpl = str_replace("<CAPTCHA>","<input type='text' name='userinput' class='input' value='' id=\"userinput\"/>&nbsp;&nbsp;&nbsp; <label for=\"userinput\">". $captcha_insert_message ."</label><br /><br /><img src=\"./includes/captcha.php\"><br><br /> ",$tpl);

}

with:


else

{

// we use our special designed language templates.

//if( isset($_GET['x'])&&file_exists( "templates/".$cfgrow['template']."/".$_GET['x']."_".$language_abr."_template.html"))

if(file_exists( "templates/jj2/image_se_template.html"))
{

//if (eregi("[.]",$_GET['x']))

// die("Come on! forget about it...");

//$tpl = file_get_contents("templates/".$cfgrow['template']."/".$_GET['x']."_".$language_abr."_template.html");
$tpl = file_get_contents("templates/jj2/image_se_template.html");

//next 1 line for CAPTCHA hack --- insert by Chaney SUN

$tpl = str_replace("<CAPTCHA>","<input type='text' name='userinput' class='input' value='' id=\"userinput\"/>&nbsp;&nbsp;&nbsp; <label for=\"userinput\">". $captcha_insert_message ."</label><br /><br /><img src=\"./includes/captcha.php\"><br><br /> ",$tpl);

}



If I do that, the swedish archive gets broken BUT the captcha does work on the swedish image comment function. Some errors in finding my swedish templates?

I hope someone here can help me. It works if you try it in the english version.
Even if you don't know swedish the links are placed on the same spot so it shouldn't be too hard to figure out for debugging.

Thank you very much in advance. My brain is toast now.

[Dennis]

Jesper, you should not code the image_template manually. The template selection is dynamically based on $_GET['x'], so doing this doesn't makes any sense.

[jesperj]

Dennis,

Ok. I have to look into how to make a proper template then, since if I understand your answer correctly, the one I'm using now is not correct.

Alas, that will have to wait till a day when I'm not zombified by depressive symptoms.

Thank you.

A lot of things don't make sense.

[Dennis]

Perhaps you could send me the template so I can have a look.

[jesperj]

Oh Dennis :)

That is a very sweet offer.

You must have better things to do with your time but how can I resist if you say so.

I will pm you an URL where I have uploaded a zip with the files.

Thank you very much!

Jesper

[mauritz]

Nice, it works for me.
Now just wait and see if it stops the spam flood ;)

But one question; how can I adjust the position of the field, text and the captcha image. Right now it's first the field, then a text (type over the code please) and below that the captcha image.
Is it possible to adjust these things?

[sentinel]

you've to change 2 lines in the index.php file

the following snippeds assume you're using the addon for pp 1.6

line 260 and 272:
$tpl = str_replace("<CAPTCHA>","<input type='text' name='userinput' class='input' value='' id=\"userinput\"/>&nbsp;&nbsp;&nbsp; <label for=\"userinp
ut\">". $captcha_insert_message ."</label><br /><br /><img src=\"./includes/captcha.php\"><br><br /> ",$tpl);


you have to modify the second part of the str_replace command (beginning with "<input type... ") the way you want. but change the code the same way in both lines in case you want to switch the template (comments in popup or not)

[GeoS]

Its better to put such code into the addon file.

[sentinel]

that's right.
it would be more confident do split up the parts (text/formfield/picture)into single variable which can be placed individually in the template.
but still, this captcha is a hack. which might change depending what the team plans todo with workspaces or what one's able to implement inside em.

[Dennis]

Well I examined the code and a hack is not necessary anymore for PP 1.7.

[sentinel]

that's nice thx for watchin

[Stefanel]

Hello!

This is my first install of pixelpost and I think it's great, but, I know that spam comments can be a pain in the a** sometimes because I've experienced it a lot on my wordpress based blog.
Anyway, can captcha be used on a fresh install of pixelpost 1.6?

[sentinel]

the current captcha "addon" can be used with pp 1.6 yes.
there's a readme.txt inside the package which explains the installation in detail.

[edit]
be sure to download the according version at the first page of this thread for pp 1.6!

[floime]

i think i have a little porblem with the captcha - i use the newest version and pp 1.6 and a user mailt me that it isnt possibel for him to leave a comment because the code he writes in the box is always wrong (it works only a few times)- he's using firefox (i don't know which version) - is there a known problem -- or have i done something wrong ?

MfG floime

[sentinel]

yes there've been such issues already in the past.
i must confess i have not been able to solve (and reproduce) the problems (on my server) yet.
(and am i'm still open for hints)

one possible solution which seems to work from time to time is to delete the cookies concerning your pblog and clean the cache .
u got a pm


for those who experience(d) the same problem
try to replace the anti_spam_addon.php with the content of the following file
anti_comment_spam.php (http://www.digitalview.at/pp-addons/anti_comment_spam.php.txt)
i'm currently using this one on my blog without any error-reports (or my visitors aren't so nice as yours are ..)

'cause pp 1.7 is released stable, whoever wants to use captcha stuff besides defensio/akismet,
take a look at the extensions section done by dennis (http://www.pixelpost.org/extend/addons/comments-captcha/)

so this hack has an end here
*sigkill*
