Hi derrida,

You should take some time and explore the DevNet on Adobe's site.  There are some great resources there free for the taking:

hi Jason
i am stuck when i need to create the rsComments with the sql query.
they use the interakt extension, i need to do it alone.
but in teir files they have this qsl :
SELECT blg_comment_com.idart_com, blg_user_usr.username_usr, blg_comment_com.text_com, blg_comment_com.date_com, blg_comment_com.valid_com FROM (blg_comment_com INNER JOIN blg_user_usr ON blg_user_usr.id_usr=blg_comment_com.idusr_com) WHERE blg_comment_com.idart_com=".HTTP_GET_VARS["id_art"]." AND blg_comment_com.valid_com=1 "

so i entered this sql code to the sql section in the rsComments recordset and i get this type of error message:
mysql error: 1064
and they point out that the problem is with the last line:
WHERE blg_comment_com.idart_com=".HTTP_GET_VARS["id_art"]." AND blg_comment_com.valid_com=1 "
and actually i can read and understand most of the code, but not the HTTP part.

can you help me?

best regards

derrida

I think it's just a typo...

HTTP_GET_VARS should either be $HTTP_GET_VARS or more simply $_GET

hi jason
thanks, it works. i had the feeling that the problem is there but i knew about $_GET but not about $HTTP_GET_VARS.

Hi ron,

Glad it was a simple fix.

$_GET and all of the "$_" arrays are the superglobals that were introduced in PHP 4.1 (I think it was 4.1).  However, it is possible to turn them off at the config level.  In that case, the older arrays of $HTTP_GET_VARS and $HTTP_POST_VARS are available.

Just make sure that you are using $_ or $HTTP_ consistently throughout your scripts if both work.  They are not equivalent.
