sending multiple attachments from databases

[TM-GNM]

Hi! A ex-staffer  created a functions file that emails to me, as attachments, CSV files of 21 elists in the MySQL databases of multiple websites. It creates one email per CSV file. I'd like to changed the code to send multiple files per email. (So can I save them in my computer by save-all instead of one at a time.)

I've attached the current code. Instead of 21 separate emails, I'd like just 4, divided like so:

'website-subscribers' should include 3 attachments:
                                    'media',
                                    '30days',
                                    'footsteps',

‘dada' should include these attachments:
                'blessings',
                'booknews',
                'dailyreflections',
                'earlydr',
                'eastdr',
                'notify',
                'eclass',
                'prayernetwork',
                'reflexiones',
                'saints',
                'sundays',

'download-link-users' should include these attachments:
                                                '30days',
                                                'footsteps',
                                                'gnm',
                                                'es',
                                                'media',
                                                'wb',

'7warriors' should be sent by itself.

Please help! I'm in over my head. Thank you!

Do you have some php code to show us how far you are?  Do use the <> icon for the code when you post it here.

change the code to use arrays for the sets of data under each major category, rather than processing each list/site separately. write two new functions (keeping the old code as is.) the new add_all_subscribers_lists_array() function would build arrays of parameters inside the inner foreach() loop, then call a new add_subscriber_list_array() function once, after the end of the inner foreach() loop. the code in the new add_subscriber_list_array() function would loop over the arrays of input parameters, query for the data and build each .csv file, then call the wp_mail() function once, supplying an array of the attachments.

of some concern is that the code is creating a new database connection for each list/site. are all these databases on the same database server, with the only difference being which database is selected? if so, the code only needs to select the database before each query, rather than create an entirely new connection for each list/site query.

for the 7warriors .csv, the posted code only outputs three headings, but there are four columns of data. to fix this, you would define a specific $column_names array inside the 7warriors conditional logic.

Thank you. They are all on the same server -- different websites but same server.
