I want pass post-fields to own php-function and then display the output in Views loop editor.
What I'm trying to get is function that parses output from 2 different custom fields containing date-time (2017-09-21 11:00:00). I can compare and format them easily in php-funtion, but not in Views Loop.
How do I pass those two fields to my own php-function and display result in loop?

Hi Jussi,

Thank you for contacting Toolset support. This will require some good level programming expertise, below is the approach that you would follow:

1. How do I pass those two fields to my own php-function and display result in loop?
==> You can make shortcode for your php function and pass those fields in shortcode attributes, like:

[my_custom_shortcode attr_1="field1_shortcode" attr_2="field2_shortcode"]

- Then after processing those fields you can return result back to the shortcode for display..

- Here is WP shortcode API: https://codex.wordpress.org/Shortcode_API

2. View also has conditional Shortcode to compare things and you can use your custom functions in conditions, here is the doc:
https://toolset.com/documentation/user-guides/conditional-html-output-in-views/using-custom-functions-in-conditions/

You can also use your own custom shortcodes in Views conditional output:

Please note that above info is specially for someone having WP programming experience.
Thank you

Thank you for guidance. I tested this, and the solution seems to work.

I put following php-code to my themes functions.php:

function this_is_test_shortcode_func( $atts ) {
	$attlist = shortcode_atts(
		array(
			'first' => '(no first)',
			'second' => '(no second)',
		), $atts, 'this_is_test_shortcode' );
	return "Output 1: " . $attlist['first'] . " / 2: " . $attlist['second'];
}
add_shortcode( 'this_is_test_shortcode' , 'this_is_test_shortcode_func' );

And this row to Loop Output Editor:

[this_is_test_shortcode first="[wpv-post-title]" second="[wpv-post-date]"]

It outputs nicely those two fields as a return. Next step is to build the date parser in this php-function.
