2 Questions : smileys&cookies

3.1.  How do I add more smilies to my forums?

Adding more smilies to your forums is not difficult, but it involves editing one of the scripts that comes with PunBB. Here's a step-by-step instruction. Having very basic knowledge of PHP or programming in general is recommended.

Copy the smilies you want to add/change to into the directory img/smilies/.
Open up the file include/parser.php in a text editor and locate the line that starts with "// Here you can add additional smilies if you like" (it's almost at the top of the file). There you will find two PHP arrays - $smiley_text and $smiley_img. $smiley_text contains the character combinations for the smileys (e.g. or ) and $smiley_img contains the filenames of the smiley images (e.g. big_smile.png or roll.png).
For every new smiley that you want to add, add a character combination to $smiley_text and a filename to $smiley_img. Please note that you must escape the character ' (singlequote) with a backslash if you use it in any of your smilies (e.g. ':rock\'n\'roll:'). Singlequote must be escaped so that PHP can understand that it is not the end of the string, but a character in the string. The same goes for backslash. If your smiley contains a backslash, just must escape that backslash with another backslash (e.g. ':\\').
Once you've added your smileys above, you should pay attention to the row below the smiley arrays. It says that if any of your smilies contain any of the characters &, ", ', < or >, you must uncomment the row thereafter.
Finally save/upload the file and try it out. A list of all installed smilies can be found at the bottom of the help text in help.php.
If you get a PHP error message stating that it encountered a "Parse error", you probably forgot to escape a singlequote or backslash character in the $smiley_text array.
