Gravity Form Checkbox Values

This post is an extension of Gravity Forms – Collecting Select Box Value.
In this demo we are capturing the values from a group of checkboxes.

Demo with Checkboxes

    Select the items to add to your order
  • ...we'll grab the checkbox values here
/**
* Wrap our JS for capturing values
*/
var checkboxHandler = {
 
 	//Change these IDs to match your form
 	checkboxFieldId: 'input_5_3',  //checkbox container ID
	outputFieldId:   'input_5_2',    //hidden field to capture values
	
	checkboxField: null,
	outputField: null,
	
    /*
	Listen to Checkboxes
	---------------------- */
    init: function() {
    
		this.outputField = document.getElementById(this.outputFieldId);
		
		if( typeof this.outputField === 'undefined' || !this.outputField ) {
			console.error('Missing output field ' + this.outputFieldId);
			return;
		}
		
        this.checkboxField = document.getElementById(this.checkboxFieldId);
        if(typeof this.checkboxField === 'undefined' || !this.checkboxField) {
			console.error('Missing checkbox field ' + this.checkboxFieldId);
            return;
        }
         
        jQuery(this.checkboxField).on(
			'change',
			'input[type=checkbox]',
			{
				checkbox: this.checkboxField,
				output:   this.outputField
			},
			this.setValues
		);
    },
    
	
    /*
	Set text (or hidden) field to list of checkbox values
    ----------------------------------- */
    setValues: function(ev) {
	
		var fields = ev.data;
        var valueString = '';
		
		jQuery(fields.checkbox).find('input:checked').each( function(i){
			valueString += this.value + ', ';
		});
		
		fields.output.value = valueString.replace(/, $/, '');
    }
};

jQuery().ready( checkboxHandler.init() );

If you are using a child theme or custom theme you can add this code to its JavaScript file.
Otherwise use WordPress’ wp_register_script and wp_enqueue_script functions to load a new file.
The value of the hidden/text box can then be included in your Gravity Forms notification.
