Hi all,

I have written a few usertags which needs access to the database of CMSMS. Up to PHP 5.5 I could easily use

mysql_query("TRUNCATE TABLE `buffertime`");

which works fine. With PHP 7 I need a second parameter:

mysqli_query($link,"TRUNCATE TABLE `buffertime`");

What is a correct, predefined variablename for $link containing the current database?

As a workaround I wrote a function open_db(), which will do the job using mysqli_connect and set $link = open_db().

But that cannot be the solution to the problem. Any hint?

Thanks in advance!

Regards Peter

this works for me (on php 5.6.x or 7.0.x)
to access another database (not cmsms)

Code: Select all

$db = NewADOConnection('mysqli');
//assuming those $db_ vars are defined:
$db->Connect($db_host,$db_user,$db_pw,$db_db);

to access cmsms i think this is all that's needed:

Code: Select all

$db = cmsms()->GetDb;

and then run your query:

Code: Select all

$query = "SELECT * FROM sometable";
$dbr = $db->Execute($query);
while( $dbr && !$dbr->EOF ) {
  print_r($dbr->fields);
  $dbr->MoveNext();
}

you may need to reconnect to cmsms with

Code: Select all

adodb_connect();

It's not difficult to do that. $link means only connection ID.

You can get for current db with

Code: Select all

   $db = cmsms()->GetDb();
   $dbid = $db->connectionId;

, so this will work

Code: Select all

   $result = mysqli_query($dbid , 'select * from cms_content;');

Hi chandra,

thanks, that is exactly, what I was searching for! It works great.
