Onderwerp: [PHP] str_replace probleem

In bestaande code, Ekomite CMS GuestBook snippet [1], probeer ik een
optie in te bouwen om tekst smilies ( :-) ) om te zetten in een image.
Dit probeer ik met str_replace:

$message = str_replace(":-)", "<img
src=\"./assets/images/smilies/a1.gif\">", $_POST['message']);
$message = str_replace(":-(", "<img
src=\"./assets/images/smilies/a2.gif\">", $_POST['message']);
$message = str_replace(";-)", "<img
src=\"./assets/images/smilies/a3.gif\">", $_POST['message']);
$message = str_replace("", "<img
src=\"./assets/images/smilies/a4.gif\">", $_POST['message']);
$message = str_replace("", "<img
src=\"./assets/images/smilies/a5.gif\">", $_POST['message']);
$message = str_replace("", "<img
src=\"./assets/images/smilies/a6.gif\">", $_POST['message']);
$message = str_replace("", "<img
src=\"./assets/images/smilies/a7.gif\">", $_POST['message']);
$message = str_replace("", "<img
src=\"./assets/images/smilies/a8.gif\">", $_POST['message']);
$message = str_replace("", "<img
src=\"./assets/images/smilies/a9.gif\">", $_POST['message']);
$message = str_replace("", "<img
src=\"./assets/images/smilies/a10.gif\">", $_POST['message']);
$message = str_replace(":confused:", "<img
src=\"./assets/images/smilies/a11.gif\">", $_POST['message']);

De ene keer wordt het plaatje weergegeven en de andere keer de tekst.
Heeft iemand de oplossing (let wel, PHP is niet mijn sterke kant...)?
De paden (./assets/images/smilies/) kloppen.

# GuestBook - Etomite v0.6.3 - Modified 2004-11-05
# Created By: Ralph A. Dahlgren - rad14701@yahoo.com
# Usage: Create an Etomite user or admin as GuestBook owner in Etomite
Manager
# Change $defaultadmin variable to match GuestBook owner
# OR: Set $defaultadmin to an existing Admin name.
# Messages will be deposited into that mailbox, but only GuestBook
# messages will be displayed within the GuestBook listing.
#
# Var's: $gbtype - Referenced in GuestBook admin User Messages Subject
# $gbadmin - Etomite User/Admin who will receive this message
#
# Examples: [[GuestBook?gbtype=GuestBook&gbadmin=guestbook]] - Self
Explanatory
# [[GuestBook?gbadmin=someuser]] - Uses
$etomite->documentObject['pagetitle'] for $gbtype
# [[GuestBook?bgtype=SomeTopic]] - Uses $defaultadmin for $gbadmin
# [[GuestBook]] - Will use snippet defaults for $gbtype and
$gbadmin
#
# Note: $etomite->documentObject['createdby'] was not used for $gbadmin
intentionally
# To implement this capability would entail and additonal DB
Query before Inserts
#

$gbadmin not passed

Met bovenstaande code krijg ik de tekst, bijvoorbeeld ' :-) '.
*Nu* heb ik een comment toegevoegd zodat er maar 1 str_replace regel is
en de smiley wordt *wel* weergegeven... :

// $message = $_POST['message'];
$message = str_replace(":-)", "<img
src=\"./assets/images/smilies/a1.gif\">", $_POST['message']);
/*
$message = str_replace(":-(", "<img
src=\"./assets/images/smilies/a2.gif\">", $_POST['message']);
$message = str_replace(";-)", "<img
src=\"./assets/images/smilies/a3.gif\">", $_POST['message']);
$message = str_replace("", "<img
src=\"./assets/images/smilies/a4.gif\">", $_POST['message']);
$message = str_replace("", "<img
src=\"./assets/images/smilies/a5.gif\">", $_POST['message']);
$message = str_replace("", "<img
src=\"./assets/images/smilies/a6.gif\">", $_POST['message']);
$message = str_replace("", "<img
src=\"./assets/images/smilies/a7.gif\">", $_POST['message']);
$message = str_replace("", "<img

$message = str_replace("", "<img

$message = str_replace("", "<img
src=\"./assets/images/smilies/a10.gif\">", $_POST['message']);
$message = str_replace(":confused:", "<img
src=\"./assets/images/smilies/a11.gif\">", $_POST['message']);
*/
# Query to INSERT a new GuestBook message into user_messages

Ik hoop dat het een beetje duidelijk is... ;-) Alvast bedankt voor enige
inzichten.

Prober het eens met :confused: als test case, je zult zien dat die wel
werkt.

Is ook niet verwonderlijk, er staat immers:

$nieuwewaarde=functieA($originelewaarde);
$nieuwewaarde=functieB($originelewaarde);
$nieuwewaarde=functieC($originelewaarde);

Terwijl je bedoelt:
$nieuwewaarde=functieA($originelewaarde);
$nieuwewaarde=functieB($nieuwewaarde);
$nieuwewaarde=functieC($nieuwewaarde);

Maar met str_replace kan dat ook in 1 keer:

$emo=array('' ,'' , ...);
$img=array('<img src="/path/a1.gif">', '<img src="/path/a2.gif">','<img...);

$message=str_replace($emo,$img,$_POST='message']);

Hoe ik daar overheen heb kunnen kijken...

Bedankt, het werkt!
