    Hilfe zur Verständnis eines Skriptes

    Hey,
    ich hab auf meiner Seite jetzt ein Kommentarskript eingebaut, läuft auch super, doch leider bei der Seite wo man ein Kommentar hinterlassen kann wird alles auf einmal dick geschrieben.

    PHP:
    <?
    //Please set the following variables for your mysql database:
    $db_hostname  =  "localhost" ;   //usually "localhost be default"
    $db_username  =  "xxx" ;   //your user name
    $db_pass  =  "xxx" ;   //the password for your user
    $db_name  =  "xxx" ;   //the name of the database



    // connect to database
    $dbh  =  mysql_connect  ( $db_hostname ,  $db_username ,  $db_pass ) or die ( 'I cannot connect to the database because: '  .  mysql_error ());
    mysql_select_db  ( $db_name );



    //for security, html is not allowed, so bbcode is used for formatting

    //START 3rd PARTY CODE:  I did not write this

    ich kenn mich nun leider so gar nicht mit php aus, wo genau steht das er alles dick macht bzw. größer? Irgendwas muss da ja stehen :-/

    BWs sind garantiert!

    AW: Hilfe zur Verständnis eines Skriptes

    Such das Script nach

    font-weight: bold;
    <strong>
    <b>

    ab, damit kann der Text Dick geschrieben werden.

    AW: Hilfe zur Verständnis eines Skriptes

    Ich hab das Script mal durchsucht. Nicht zu finden war: <strong>, <b>, <bold>. Demnach ist dein Problem im CSS-Teil zu finden:

    ----------------------------------------------------------------------------------------
    Zeile 1:
    .bold {
    font-weight: bold;
    }

    Die Klasse wird in Zeile 176 verwendet:
    $Text = preg_replace("(\[b\](.+?)\[\/b])is",'<span class="bold">$1</span>',$Text);
    ----------------------------------------------------------------------------------------
    Zeil 85:
    .quotecodeheader {
    font-family: Verdana, arial, helvetica, sans-serif;
    font-size: 12px;
    font-weight: bold;
    }

    Die Klasse wir in Zeilen 211 und 223 verwendet:
    <td class="quotecodeheader"> Code:</td>
    ----------------------------------------------------------------------------------------

    Ich denke damit habe ich deine Suche etwas eingegrenzt. Wobei ich sagen muss, dass das für mich alles normal aussieht.
    Cheers!
