Conditional Logic and Pre Population

Hey Guys -

My website sells multiple tours - some of these tours depart from multiple departure locations and all have various little unique differences that are reflected in the forms.

So the forms aid the user experience, so that the interaction with Salesforce is smooth, and also so that it is easier for me to make large scale changes to forms I have decided to make a 'super' form that can be used on all tour pages (and then a couple others for non tour pages). For this to work there will be various entry fields that are conditional - many of these fields would be conditional on a field containing the name of the tour the user is interested in.

The problem is my Boss doesn't want the user to have to choose the tour they are interested in, so I was wondering if there was some way I can pre-populate a field with the tour/page name (or perhaps default to the relevant tour?) and yet still have other fields be able to rely on it for conditional logic.

An example of two different forms:

http://www.fraserfree.com.au/fraser-island-tours-hervey-bay/fraser-island-tour-3-day-cool-dingo

Any idea greatly appreciated!

Other choice would be to use the shortcode to populate these fields.

Pass the tour choice to the form when you embed it into the page and you can use the same form for every tour - [gravityform id=1 field_values='tour_choice=2day']

With a widget the shortcode call variables won't work - only choices are hooks like you are working with, referral arguments, or (probably easiest for your form) the pre-configured default values.

If you name the Post / Page with the tour's identity, you can use the default value - insert variable field on an admin only (to hide from visitors) field. - http://grab.by/b3FS

This does limit you to a single line or similar field, if you want to do a drop down or radio button field you will have to go with the hook.

As for your hook, it can be done linking to the internal WordPress function get_the_title()

/*---------------------------------------------------------------------------------*/
/* Gravity Forms Functions - Get page fields from WordPress                        */
/*---------------------------------------------------------------------------------*/

//  Assigns the name of the current post/page to Gravity Forms field 'which_tour'
add_filter('gform_field_value_which_tour', 'get_the_title');

One limit I have notices with this is if the widget is displayed on a category list it will capture the name of the oldest post in the category.

No problem, I'm new to php too but I've always been good at tearing apart coding.

Most of the snipets you find here are creating a custom function, and then passing the result to the Gravity Forms variables. To do this there are two parts - the function, and a statement to assign the result to a variable.

In this case, the WordPress function get_the_title() already exists, so you do not have to create the function and assign the variable to return.

The add_filter() function needs to be encased in php coding in the functions.php file. You can ether copy the single line into the existing functions list, or add it to the end of the file with it's own php call.

<?php
add_filter('gform_field_value_which_tour', 'get_the_title');
?>

Check the 'Allow field to be populated dynamically' and then enter which_tour in the box.

Be careful editing the functions.php - if the code has an error in it it may stop the WordPress engine from working and you will need to correct the error from outside the WordPress editor (control panel, ftp, etc).
