Can anyone help me I'm trying to read two results from a function by passing
them out via an array but I'm not sure how to access them once I have done
that. In the PHP manual it shows a list call which I can't seem to even find
what the hell it does the code below runs without any errors but does not
seem to work.
here the function gest passed the language and currency preference and a
variable (1,0) to decide what it will do with them - update the preferences
of the user or read out and define the preferences. (once updated I want it
to read out the prefs aswell)
function PrefChange($lang,$curry,$state){
global $DB_Server, $HTTP_Host, $DB_Login, $DB_Password, $DB_Name, $DocRoot ;
if ($state){//read preferences from page
if (!($result = mysql_db_query($DB_Name,"SELECT language_pref,
currency_pref FROM users WHERE user_id ='$cookie_user'"))){
DisplayErrMessage(sprintf("internal error %s %s %s %d:%s\n",$DB_Server,
$DB_Login, $DB_Password,
mysql_errno(), mysql_error()));
while ($row = mysql_fetch_array($results)){
$lang_pref = $row["language_pref"];
$currancy_pref = $row["currency_pref"];
return array($lang_pref,$currancy_pref);
}
}
} else {///update preferences from page
if (!($result = mysql_db_query($DB_Name,"UPDATE users SET
language_pref='$lang' AND currency_pref='$curry' WHERE
user_id='$cookie_user'"))){
DisplayErrMessage(sprintf("internal error %s %s %s %d:%s\n",$DB_Server,
$DB_Login, $DB_Password,
mysql_errno(), mysql_error()));
PrefChange(0,0,1) ;
}
}
}
an example of what I'd like to do when calling the function (here I'm only
reading the prefrences from the DB ), a select box that is showing the
preference that is chosen with the preference read from the above function
and the list created by the function below
<select name="form_lang_pref" style="font-family:verdana,
Arial;font-size:8pt" CLASS:menu">
<?
list ($form_language_pref, $form_currency_pref) = PrefChange(0,0,1);
$select_id = $form_language_pref;
$db = mysql_connect("$DB_Server", "$DB_Login, $DB_Password");
mysql_select_db("$DB_Name",$db);
$results = mysql_query("SELECT * FROM language ORDER BY language
",$db);
while ($row = mysql_fetch_array($results)){
$rowid = $row["language_id"];
$name = $row["language"];
if ($rowid == $select_id) {
echo("<option SELECTED
value=\"$id\">$name</option>\n");
} else {
echo("<option value=\"$id\">$name</option>\n");
}
// endwhile;
}
echo("</select>");
?>
