hi everybody,
i'm making a little testscript that uses adodb to connect via PHP4 to a
postgresql 7.2 db. something like this:
=== file index.php ===
<?php
include_once('adodb/adodb.inc.php');
$conn=ADONewConnection('postgres7');
if (@$conn->PConnect('localhost','username', 'password', 'dbname')) {
include("show.php");
}
?>
=== eof ==============
=== file show.php ===
<?php
switch ($action) {
case start:
start();
break;
case listing:
listing($bereik);
break;
default:
start();
break;
}
function start() {
global $conn;
echo "<h2>Choose a letter</h2>\n";
$lett=array(A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z);
foreach ($lett as $i) {
echo "\n\t<a href='show.php?action=listing&range=$i'>$i</a> ";
}
}
function listing($range) {
global $conn;
echo "<h2>Range: ", $range, "</h2>\n";
$rs=$conn->Execute("select * from rolo where name like '$range%'");
}
?>
=== eof ==============
that's all. the idea is that the users clicks a letter, the function
listing() is called, and a selection is made. the problem is the
visibility of $conn. it's visible in index.php and in start(), but in
listing() it's gone!?! the line $rs=$conn->exectute in listing()
produces an error "call to a member of a non-object".
what am i doing wrong? how do i make $conn visible in listing()? TIA
for any pointers / help!
