Faux Subsummaries with Variable Height Rows

Recently we’ve looked at two methods to generate a “faux” subsummary to address a shortcoming of FileMaker native subsummaries… namely that in a multipage report you can have orphaned entries at the top of a given page with no indication of what parent entity they belong to. The methods were documented here: Conditional Summary Report […]

Faux Subsummaries via JSON + Virtual List

Today we’re going to take another look at a challenge we discussed last time (in Conditional Summary Report Header)… namely how to cajole FileMaker into displaying a subsummary, or a reasonable facsimile thereof, at the top of a report page when items in the group begin on an earlier page. Demo file: Faux Subsummaries via […]

Conditional Summary Report Header

Recently I received an email wondering… When printing a multipage report sorted by a sub-summary, is there a way to display the sub-summary heading on the following page when it breaks across two or more pages? There are various approaches one might take, and I actually buried one of those approaches inside an article + […]

Thinking About JSON, part 3

This a quick followup to last month’s part 2, because today I want to to dig a little deeper into JSONSetElement and take a closer look at the first argument: As I wrote last time… Part of what makes JSONSetElement so powerful is that it can be used both to create new entries, and to […]

Thinking About JSON, Part 2

This is a follow up to Thinking About JSON, Part 1. Last time we were primarily concerned with learning about JSON paths and structures, and reading JSON. This time around we’re going to look at creating and manipulating JSON. Demo file: winery-json.zip (If the above screen shot looks familiar you have a good memory, because […]

Virtual List Reporting with JSON Arrays

Acknowledgement: As always a huge thank you to Bruce Robertson, for inventing virtual list, and for many other contributions to the FM community over the years. Introduction As a follow up to my recent “Virtual List on Steroids” presentations at DIG-FM and dotFMP, today I want to take a fresh look at using JSON arrays […]

Fast Summaries Re-revisited

My recent “Virtual List on Steroids” presentation at DIG-FM, and the preparation of a revised version to give at dotFMP next week, has prompted me to reconsider certain assumptions re: optimizing performance both locally, and across a LAN and/or WAN. Specifically, there are two things we’re going to look at today. First, a way to […]

Thinking About JSON, part 1

I’ve been working on a couple large JSON projects over the last few months, and with the one year anniversary of FileMaker having built-in JSON capabilities just around the corner, this seems an opportune moment to share some reflections and opinions (some of which may contradict JSON-related opinions I have expressed previously). Demo file: json-sandbox.zip […]

Custom Field-Based Value Lists

Introduction Does this sound familiar? You’ve rolled out a solution that includes a single-record Settings table where authorized users can enter/update various system-wide settings, including one or more fields where the items will appear in popup menus… and then comes the inevitable question: Why don’t items in popup menus appear in the order I entered […]

Editor’s note: today we have a guest article written by John Weinshel, who has been quietly contributing to the FileMaker community for 20+ years. John’s thoughtful postings have helped developers at all levels of expertise, and I’m pleased to present his thoughts on Tableau here on FileMaker Hacks. Demo files: exposed-by-tableau.zip (6Mb, contains two .twbx […]

Sorting on a Field Rep > 1

Recently, in a virtual list report, I had a need to sort on rep number 2 of a repeating field called cell_text_r. FileMaker does not offer an obvious way to script a sort on a field rep > 1, and I had worked around the problem in the past by A. defining some special non-repeating […]

Scrolling the Unscrollable

Demo file: scrolling-the-unscrollable.zip Howard Schlossberg’s presentation on popovers (FileMaker 13 Popovers) has inspired me on multiple occasions… a favorite takeaway is the idea that you can have a scrolling check box set within a popover. The trick is to size the field as tall as necessary to display all the values (this is an extreme […]

Reciprocal Linkage, part 3

I thought after part 2 that this technique had been thoroughly discussed and dissected, but Geoff Gerhard of Creative Solutions writes to point out that, if the goal is to have as few moving parts as possible, the table occurrence (TO) count can be further reduced, from four to three… …and has provided a demo […]

Reciprocal Linkage, part 2

This is a quick follow up to last week’s article on reciprocal (bi-directional) linking, and will assume the reader is familiar with that material. Paul Jansen of APJ Computing Solutions sent in a revision of one of my files demonstrating that, among other things, the graph could be a good deal leaner (as per my […]

Reciprocal Linkage

Challenge: in a multiuser document management system, facilitate the linking (and unlinking) of any document with any other. Make it clear which documents are linked to the current document, and make sure the approach is multiuser friendly — in other words, allow document records to be linked and unlinked even if one or both of […]

JSON Array + Virtual List

Over the last few postings we’ve been looking at using JSON with Virtual List… and prior to today, our focus has been on JSON structures using name/value pairs. Well today we’re going to switch our attention to basic JSON array structures. Demo file: json-array-plus-virtual-list.zip (requires FileMaker 16.02 or later) Apart from using JSON arrays instead […]

Virtual List Reporting + JSON

Today we’re going to look at an alternative approach to the multi-window VLR technique we examined last month in Virtual List Reporting part 3, utilizing and extending techniques introduced in last month’s JSON + Virtual List. To avoid needless repetition, today’s article will assume the reader is familiar with that material. Demo files: vlr-plus-json-v1 and […]

JSON + Virtual List, part 2

Demo file: json-plus-virtual-list-part-2.zip This is a short follow-up to part 1, to demonstrate an alternative idea re: JSON date encoding. As you may recall, JSON does not have a “date” type, and one of our goals is to encode and decode JSON dates in a region-agnostic manner (e.g., encode in a region where MM/DD/YYYY is […]

JSON + Virtual List

One nice thing about FileMaker being on a yearly release cycle is that there is always something new to learn and write about… and, having just attended a couple highly informative sessions on the topic of JSON (JavaScript Object Notation) at Devcon 2017 — thank you Todd Geist and Anders Monsen — it is clear […]

FM 16: Pseudo Indexing

During our recent discussion of SortValues and UniqueValues, I made passing reference to an article I wrote a few years ago on the topic of “pseudo indexing“, i.e., displaying a list of unique values for a specific field for a found set, rather than for all records. Well today we’re going to dust the pseudo […]
