Shoutbox Spams

[Guest SwordKing]

Hi Community,

I just created a shoutbox. Day by day I get senseless spams in it. I think there are a few oppurtiunitys how to keep my shoutbox clear and safe.
A security code would maybe help and a blocking of 'www' or 'http://' !

How do I do that? If you have any suggestions, please le me know. thanks

What is it? I don' know what you mean

[.josh]

as in, that's the google keyword you want to use. image verification.

captcha is a system of text in images used to block spiders from doing stuff such as registering on sites and such.

[marcus]

Yeah, you can use captcha for the security code. And to block http:// and www

You can do:

[code]
<?php
$message = $_POST['message'];
$message = str_replace("http://","",$message);
$message = str_replace("www","",$message);
?>
[/code]

okay. I understand that, but how to show an error? I used

[code]if($action=="add" AND $cont<>"www" AND $cont<>"http://" ) {
[/code]

But if someone posted "http://myurl.de" it's useless. What can I use instead of <> ?

The operator you're looking for is "!=". (not equal)  You should use "&&" instead of "AND".

well AND doesn't really matter unless he's mixing operators cuz AND and && has a different order of precedence.  In this particular condition (and in most conditions) it really doesn't matter.

i think what you are really trying to do in this condition is for instance this:

[code]
if ($action == "add") {
  if((!substr($cont,"http://") && (!substr($cont,"www")) {
    // add stuff here
  } else {
    // is spam
  }
}
[/code]

[code]Parse error: parse error, unexpected '{' [/code]

there stand :

[code]  if((!substr($cont,"http://") && (!substr($cont,"www")) { [/code]

Should I post the whole code?

[marcus]

[code] if(!substr($cont,"http://") && !substr($cont,"www")) { [/code]

[.josh]

i forgot some )'s. sorry:

[code]
if((!substr($cont,"http://")) && (!substr($cont,"www"))) {
[/code]

[Guest SwordKing]

thank you. thats it.

I will use it that way. When I have additional questions, I'll come back.

hi I am here once again.

There is a problem with your code. Or maybe I did wrong :

[code]if ($action == "add") {
  if(!substr($cont,"http://") && !substr($cont,"www")) {
    $add="INSERT INTO shoutbox (name, content) VALUES ('$name', '$content')"; $sqlaction=mysql_query($add);
  print "entry <strong>done</strong> ...  [ <a href=\"index.php?show=news\">go on</a> ]";
  } else {
  print "Please <strong>don't</strong>Spam !";
  }
}[/code]

He is always showing "Please don't Spam". I am not able to insert an entry.

What's wrong here?

I THINK you might have your variables mixed up.

Is the box with the shoutbox message in called $content? If so then use the following:

[code]if ($action == "add")
{
if(!substr($content,"http://") | !substr($content,"www"))
{
$add="INSERT INTO shoutbox (name, content) VALUES ('$name', '$content')"; $sqlaction=mysql_query($add);
print "entry <strong>done</strong> ...  [ <a href=\"index.php?show=news\">go on</a> ]";
}
else
{
print "Please <strong>don't</strong> Spam !";
}
}[/code]

[Guest SwordKing]

That's not the right solution.

It's always [quote]Please <strong>don't</strong> Spam[/quote] once again.

Try:
[code]
<?php

if ($action == "add") {
  if(strpos($content, "http://") === false && strpos($content, "www") === false){
  $add = "INSERT INTO shoutbox (name, content) VALUES ('$name', '$content')";
  $sqlaction = mysql_query($add);
  print "entry <strong>done</strong> ...  [ <a href=\"index.php?show=news\">go on</a> ]";
  } else {
  print "Please <strong>don't</strong>Spam !";
  }
}

?>
[/code]

ahh thank you. That's it ! :)
