Features

  • Repeat groups of fields multiple times

  • Use Javascript to manipulate the repeater
  • Customize the add and remove button's HTML
  • Use Gravity Forms pre-populate hooks and filters like normal
  • Supports Conditional Logic!

Issues

  • Not all fields are currently supported.
  • Ajax enabled forms are not yet supported. (Ajax will be automatically disabled on forms with repeaters)

Shortcodes

You can place shortcodes inside of input labels, input descriptions, and HTML blocks!

  • [gfRepeater-count] - Will output the current repeat number.
  • [gfRepeater-buttons] - Will output both the '+' and '-' buttons.
  • [gfRepeater-add] - Will output the '+' button.
  • [gfRepeater-remove] - Will output the '-' button.

CSS Classes

You can use these CSS classes in the in the "Custom CSS Class" setting to do different things.

  • gf_repeater_hide_add - Will hide the '+' button if placed in the repeater end css setting.
  • gf_repeater_hide_remove - Will hide the '-' button if placed in the repeater end css setting.

Javascript

Functions

You can use Javascript to manipulate the repeater.

  • formId is your form's Id number assigned by Gravity Forms.
  • repeaterId will depened on how many repeaters you have in your form. (The first repeater's ID is 1, second is 2, etc.)
  • repeaterChildId works the same way and depends on how many times the repeater has been repeated.
  • These functions will not allow you to repeat more than the set max and unrepeat more than the set min.

// Repeats the repeater once.
gfRepeater_repeatRepeater(formId, repeaterId);
// Un-repeats the repeater once. repeaterChildId is optional.
gfRepeater_unrepeatRepeater(formId, repeaterId, repeaterChildId);
// Repeats the repeater a number of times.
gfRepeater_repeatRepeaterTimes(formId, repeaterId, timesX);
// UnRepeats the repeater a number of times.
gfRepeater_unrepeatRepeaterTimes(formId, repeaterId, timesX);
// Repeats or unrepeats the repeater to get it to whatever timesX is.
gfRepeater_setRepeater(formId, repeaterId, timesX);
// Selects an element depending on the variables passed. All variables are optional besides formId. inputId also accepts '*' to select all inputs.
gfRepeater_select(formId, repeaterId, repeatId, childId, inputId);
Triggers

These triggers are assigned to the form will be fired during different repeater related events with the repeaterId and repeaterChildId attached to them.

gform_repeater_before_repeat - Fires right before a repeater is about to be repeated.
gform_repeater_after_repeat - Fires right after a repeater has been repeated.
gform_repeater_before_unrepeat - Fires right before a repeater is about to be un-repeated.
gform_repeater_after_unrepeat - Fires right after a repeater has been un-repeated.
gform_repeater_init_done - Fires after the repeater is done setting up. Also fires on the window when all repeaters are done setting up.

Usage Examples

Repeat the repeater a number of times depending on the value of a drop down field:

jQuery('#gform_6 #input_6_7').change(function(){
    var attendees = jQuery(this).val();
    gfRepeater_setRepeater(6, 1, attendees);
});

Change the value of a field if the repeater is repeated or un-repeated:

jQuery('#gform_9').on('gform_repeater_after_repeat gform_repeater_after_unrepeat', function(event, repeaterId, repeatId){
    if (repeaterId == 1) {
        var repeatCount = gfRepeater_repeaters[9][1]['data']['repeatCount'];
        var totalPrice = 27.47 * repeatCount;
        jQuery('#gform_9 #input_9_4').val('$'+totalPrice);
    }
});

Prepopulate Fields

You can set Parameter Names to prepopulate repeated fields like usual with the added ability to specify which repeated set will be prepopulated. For example, let's say we have set the parameter name for one of our repeated fields to "parem":

?parem=hello+world will result in that field being set to "hello world" regardless of how many times it has been repeated.

?parem3=hello+world will result in that field being set to "hello world" only when repeated a third time.

You can use filters as well!

add_filter( 'gform_field_value_parem', 'your_function_name' );
add_filter( 'gform_field_value_parem3', 'your_function_name' );

Also, setting the prepopulate parameter on the repeater start field will override the start setting.

Frequently Asked Questions

Can I use multiple repeaters in one form?

Yes!

Can I nest repeaters?

Unfortunately nesting repeaters is not supported at this time.

Can I change the + and - buttons to text links?

Yes! Just go to the form editor and change the Add HTML and Remove HTML settings to <a>Your Link Text</a> and they should appear as regular links on your form!
