Deprecated - Drupal core

Hi,

For multistep forms, how to set validation function for each step and redirect the form to previous step if the current step is invalid.

Thanks a lot in advance.

I'm sure the answer to this is somewhere, but I can't see it. Is it possible to have autocomplete display values that are different than the one the form returns? I have a database of "foods" that all have a numerical ID (because some of the foods have similar if not identical names based on their relationship to other foods). I still want the food to be selectable by name, but want to return the numerical ID instead of the name (which would be impossible to differentiate from other foods of the same name).

I try to execute the following code in my drupal blog page:

Adding products now...

 $dbh = dba_open( "products", "c", "cdb" )
       or die( "Couldn't open database" );

 dba_insert( "Sonic Screwdriver", 23.20, $dbh);
 dba_insert( "Tricorder", 55.50, $dbh);
 dba_insert( "ORAC AI", 2200.50, $dbh);
 dba_insert( "HAL 2000", 4500.00, $dbh);

 dba_close( $dbh );
 

It should create or open a database called products and adds some data to it.
It gives the following error.

I have been using Drupal for a long time and I don't get why term relation is part of the core.
If I made "triangle" and "square" are related... so what? What is the relation? both are polygons? why not give them the common parent "polygon"? No matter what the application is, the relationship of two terms can always mapped by the combination of different parent-child relationships.

Hello,

I have a weird problem...I have different texts, displayed via drupal_set_message....but not all are shown...no message box on single pages...Sometimes, there is a grey message box with the text content and sometimes, it does not appear...

Any others, who have the same problem or may be a solution?

Thanks,
André

My pages gives errors when I try to send email through my pages which I set in my PC. I try to change the php.ini file in order to set the account and smtp server. I try to set a gmail account. However I can't set it. I'm not sure why, but there is a possibility that the smtp server requires a password. So how can I set the password in php.ini file for the google account.
