How unique id in sugar crm modules such as in Emails module are generated?

Question

Need to know that how "create_guid" function work and how it generate IDs for different modules e.g. Emails module?

Answer 1

You may just call it like

$next_meeting->id = create_guid();

for example in logic hook. The function itself placed in /include/utils.php file .

Of course you have to save newly generated bean with

$next_meeting->save();

Answer 2

You will need to call it in following manner:

$Module_Bean->new_with_id = true; 
$Module_Bean->id = create_guid();

Note that if you assigned your own ID using create_guid function then "new_with_id" need to be set as well. You can find function at this path: include\utils.php

Following is the function body:

function create_guid()
{
    $microTime = microtime();
    list($a_dec, $a_sec) = explode(' ', $microTime);

    $dec_hex = dechex($a_dec * 1000000);
    $sec_hex = dechex($a_sec);

    ensure_length($dec_hex, 5);
    ensure_length($sec_hex, 6);

    $guid = '';
    $guid .= $dec_hex;
    $guid .= create_guid_section(3);
    $guid .= '-';
    $guid .= create_guid_section(4);
    $guid .= '-';
    $guid .= create_guid_section(4);
    $guid .= '-';
    $guid .= create_guid_section(4);
    $guid .= '-';
    $guid .= $sec_hex;
    $guid .= create_guid_section(6);

    return $guid;
}
