3. Configure the snippet
   • The basic configuration requires that you specify:
     • the form that should be used to generate the ids (form_id).
     • the source field of the Unique ID on the form (source_field_id).
     • the field where the value should be saved to (target_field_id).
     • how many IDs you want to generate (count).
   • See the Usage Examples and available Parameters below.

Usage Examples

Generate a Fixed Number of Unique IDs

new GPUID_Multiple_IDs( array(
   'form_id'         => 123,
   'source_field_id' => 35,
   'target_field_id' => 36,
   'count'           => 2
) );

Whenever form ID 123 is submitted, the Unique ID field 35 is used to create 2 new IDs. These IDs are stored in the target field 36.

Generate Unique IDs based on a Number Field

new GPUID_Multiple_IDs( array(
	'form_id'         => 123,
	'source_field_id' => 1,
	'target_field_id' => 2,
	'count'           => array(
		'field_id' => 3,
	),
) );

Whenever form ID 123 is submitted, the Unique ID field 35 is used to create new IDs. These IDs are stored in the target field 36. The number of IDs created is the value of field ID 3.

Generate Unique IDs based on a Dropdown Field

new GPUID_Multiple_IDs( array(
     'form_id'         => 123,
     'target_field_id' => 36,
     'source_field_id' => 35,
     'count'           => array(
         'field_id' => 33,
         'choices'  => array(
             'Hole in One Sponsor ($25,000)'  => 12,
             'Albatross Sponsor ($12,500)'    => 8,
             'Eagle Sponsor ($6,500)'         => 4,
             'Birdie Sponsor ($4,500)'        => 2,
             'Par Sponsor ($2,000)'           => 1,
             'Digital Media Sponsor ($1,000)' => 0,
             'Chip-In Sponsor ($500)'         => 0
         )
     )
 ) );

Whenever form 123 is submitted, the Unique ID field 35 is used to create new IDs. These IDs are stored in the target field 36. The number of IDs created depends on which option is selected from Dropdown Field 33.

For example, if Hole in One Sponsor ($25,000) is selected, 12 IDs will be generated. If Par Sponsor ($2,000) is selected, 1 ID will be generated.
