Making new input boxes

[Butterfly Bill]

I have been trying to decipher some code on the create_account.php page.

 

What I am interested in is greating some extra input boxes and radio buttons on the sign-in page. I have found the following code that seems to relate to , for example, the customer's first name:

 

$firstname = tep_db_prepare_input($HTTP_POST_VARS['firstname']);

 

$sql_data_array = array('customers_firstname' => $firstname,

 

$sql_data_array = array('customers_id' => $customer_id,

'entry_firstname' => $firstname,

 

$sql_data_array = array('customers_firstname' => $firstname,

 

tep_session_register('customer_first_name');

 

<td class="main"><?php echo tep_draw_input_field('firstname') . ' ' . (tep_not_null(ENTRY_FIRST_NAME_TEXT) ? '<span class="inputRequirement">' . ENTRY_FIRST_NAME_TEXT . '</span>': ''); ?></td>

 

 

There are some things I can't figure out:

 

"tep_db_prepare_input"

What is the "tep_db"? Is that a variable or a database name?

 

Likewise "echo tep_draw_input_field('firstname')"

This looks like it might be the code that actually draws the box on the viewer's page, but I have scoured the tutorials on w3schools.com, tizag.com, and us3.php.net and I haven't been able to find "draw_input_field" on any of them.

 

Is there somewhere in the web a truly comprehensive list of all possible commands in php? What I am mostly interested in is making simple text inputs, text area boxes, and radio buttons, and hooking them up to the SQL.

They're both custom functions written by the osC coders.

 

tep_db_prepare_input can be found in /catalog/includes/functions/database.php

 

tep_draw_input_field is in /catalog/includes/functions/html_output.php

 

That whole "functions" folder is nothing but files full of custom functions written by the osC coders
