View Full Version : DB query help

I am trying to use a code snippet from vidiscript CMS on a non vidiscript page. The problem is that this code snippet references items that are not defined on non-vidiscript pages. So basically trying to mesh the 2 together but... I lack the coding knowledge to do so.

I have this....
$db->query("SELECT * FROM sitead WHERE adname='ad2'") ; if ($db->numRows() > 0) { $ares = $db->fetch() ; $adtext = $ares['adtext'] ;

and I have $db defined via an include higher up in the page...

function db_connect() {
global $db_host,$db_user,$db_password,$db_database ;
$db = new mysql($db_host, $db_user, $db_password, $db_database) ;
if (!$db) die (ERROR);
return $db ;

when i try to run the page i get this error
Fatal error: Call to a member function query() on a non-object in C:\xampp\htdocs\index.phpon line 526

line 526 is the first code snippet in this post. I have a feeling I am getting this error because this page uses MYSQL queries and I am trying to run a mysqli or pdo query on the page (not sure which, im that dumb, haha) Totally lost, thank you!

are you connecting with the data base? and are all your names( datsbase table feld ) correct?
just re read and you are probably correct in your assumption. are you using FETCH_ ALL to return objects?

I have the db connection details included earlier in the script. and i know it works b/c the same DB is used for data immedietly before this part. mysql_select_db($db_database, $dbvidiscript);
$sql = "SELECT * FROM `category` WHERE `ptr` = 0 AND parent = '0' ORDER BY name ASC" ;
$result = mysql_query($sql) or die(mysql_error()) ;
if ($result) {
that is what works earlier in the script.

then using
$db->query("SELECT * FROM sitead WHERE adname='ad2'") ;
if ($db->numRows() > 0) {

does not. not entirely familiar with fetch_all but I did look it up and I believe my problem to be prior to putting the data into an array, like a connection problem with the style of connection im using, but i do know the connection details are correct, checked them.

ok, not 100% sure but I think you are not returning objects. it not really a mix and match the best features of PDO is perhaps the prepare and try which is major against SQL injection as you have probably read.

here look at this

So I'm a lil confused but is the $db->query type query a PDO query? I have to admit I know very little about pdo and sqli. But with a push in the right direction I can make sure I get everything I'm missing in there.

What all do I need to run a query like that? Like in terms of defining the db, and credentials etc.

its is code to return an object so is general . this is a saey guide that will give you a start with PDO better than i could.

and here is a dw extension and tut http://www.pziecina.com/design/dreamweaver/pdo_extension.php

Thanks for those tuts. I read them over and installed the extension, I wasnt able to use the DW code but it did give me the hints to get the code i needed to make the vidiscript query work. For any new pages I make i will deff use the DW extension though
