Uz si pred tym scriptom nieco odoslal prehliadacu (nejake echo alebo co). preto ti hadze headersd already sent...

Soubor, ktery zpracova data:

//Korenovy url ke skriptum

  if(function_exists("mysql_real_escape_string"))

    $str = mysql_real_escape_string($str, $GLOBALS["conn"]);

  else

  return $str;

 Header("Location: ".$_GET["url"]); 

no uz mi to ako tak funguje ale ked vlozim $message do databazy tak mi to namiesto <a href... vlozi do db "["URL"]"www.stranka.com"["/URL"]"....

no uz to facha...som neupravil vstup do db...:) dikes moc za pomoc.. :ok:

som to dalej upravit a len by som chcel vediet ci to je dobre.. robi to sice co to ma ale aj tak sa chcem uistit:)
takze tu to je:

$_POST["message"] = preg_replace(array("/((http|ftp|buhvi_co_jeste)://.*)/imU", "/(.*)/imU", "/[email](.*)[/email]/imU", "/[i](.*)[/i]/imU", "/[B](.*)[/B]/imU"),

                                     array("<a class="smallhyp_o" target="_blank" href="".BASE_URL."/redir.php?url=1">1</a>", "<a class="smallhyp_o" target="_blank" href="".BASE_URL."/redir.php?url=http://1">http://1</a>", "<a class="smallhyp_o" href="mailto:1">1</a>", "<em>1</em>", "<strong style="font-size:11px;">1</strong>"),

                                     $_POST["message"]);

Tenhle kód mi funguje, takže je to asi správně ??:ok:?

define('BASE_URL', 'http://mojestranky.cz');



$_POST["message"] = "

Blah [url(vynechat)]seznam.cz[/url] kvak [url(vynechat)]ftp://seznam.cz[/url]

[email(vynechat)]jp@seznam.cz[/email] yeah [email(vynechat)]kt.jp@seznam.cz[/email]

blah [i(vynechat)]kurziva[/i] [i(vynechat)]dalsi kurziva[/i] [b(vynechat)]tucne jej

[b(vynechat)]dalsi tucne. Blah.";



$_POST["message"] = preg_replace(array("/((http|ftp|buhvi_co_jeste)://.*)/imU", "/(.*)/imU", "/[email](.*)[/email]/imU", "/[i](.*)[/i]/imU", "/[B](.*)[/B]/imU"),

                                 array("<a class="smallhyp_o" target="_blank" href="".BASE_URL."/redir.php?url=1">1</a>", "<a class="smallhyp_o" target="_blank" href="".BASE_URL."/redir.php?url=http://1">http://1</a>", "<a class="smallhyp_o" href="mailto:1">1</a>", "<em>1</em>", "<strong style="font-size:11px;">1</strong>"),

                                 $_POST["message"]);

echo $_POST["message"];

az teraz som si vsimol ze mi tam nejde str_replace ak uzivatel pri pisani prispevku stlaci enter tak sa vlozi <br>
mam to takto...
?

....

    $_POST["prispevok"] = preg_replace(array("/((http|ftp|buhvi_co_jeste)://.*)/imU", "/(.*)/imU", "/[email](.*)[/email]/imU", "/[i](.*)[/i]/imU", "/[B](.*)[/B]/imU"),

                                     array("<a class="hypforum_o" target="_blank" href="".BASE_URL."/redir.php?url=1">1</a>", "<a class="hypforum_o" target="_blank" href="".BASE_URL."/redir.php?url=http://1">http://1</a>", "<a class="hypforum_o" href="mailto:1">1</a>", "<em>1</em>", "<strong style="font-size:12px;">1</strong>"),

                                     $_POST["prispevok"]);



   $_POST["prispevok"] = Str_Replace($najst, $nahradit, $_POST["prispevok"]);//smajlici...funguju

   $_POST["prispevok"] = Str_Replace("n","",$_POST["prispevok"]);// <br> nefunguje

    //neco jeste udelat

   MySQL_Query("INSERT INTO prispevok_forum VALUES(

Nan nahrazovani enteru BeeRkem staci funkce nl2br() ;)

no tak uz som to vyriesil cez fciu nl2br() ale aj tak by som bol rad keby mi niekto vysvetlil preco v tomto scripte nefunguje funkcia Str_Replace("n","",$_POST["prispevok"]) lebo ja tam ziadnu chybu nevidim...a bolo by to pre mna vhodnejšie vzladom na zarovnanie textu... dikes
