Answered fitness attending plugin

Hi all,

I'm looking for something for the following.

Currently I am working on a fitness website, where users have to be able to log-in and see what lessons there are in some kind of list or agenda. If they want to join a lesson they attend to the "lesson" and they get an reminder by email. In the dashboard the sport instructor is able to see who is joining a lesson on a specific day.

Has anyone some suggestions for this kind of need? I've looked at mxCalendar and ExerPlan, but it's not suitable.

Looking forward to some thoughts.

Cheers,

I can't think of any way to do that without some custom PHP code. You could make a lesson list with links that contained a lesson ID or name in the query string of the URL. Then on the landing page, a snippet could email the user and notify the instructor -- either by email or by putting the users info in a custom database table. In the second case the dashboard could show the instructor who would be attending.

Maybe someone else has a better idea.

Thanks Bob. I was thinking something similar. My php skills are OK but I am quite new to costum manipulations in ModX, do you have a good starting point?

Any other thoughts?

There's not much to it. You just put a snippet tag like the following on the page and put the PHP code in a snippet with that name. The tag is replaced by the return value of the snippet, and if you don't want anything there, you just return ''.



If you need to send information to the snippet you add a question mark and parameters preceded by & and with the value in back-ticks:



Then in the snippet:




The $scriptProperties array always contains all the properties as an associative array. The default value is only set if the property is not sent in the tag.

The snippet calls I knew but, this explanation was new for me, thanks. What I really meant was a starting point on how to use the modx API to use and manipulate the database plus how I can display data in the manager.

Thanks for your help.

Ah great, this is helpful. What I mean is the following. I probably have to create a form where people can attend to a lesson. These lessons can come from an XML or the database. The people who attend to the lesson, have to be listed somewhere in the manager so the instructor can see who is coming. So I guess, I have to create some kind of environment where that data shows up.

Thanks in advance bob, I appreciate it.

How you approach that depends on whether they need to see this information in the Manager (after logging in), or in the front end. Most people like to keep users out of the Manager if possible.

As for the data, you can put it anywhere you want. In a custom table in the MODX database, in a file, in a chunk, etc.

If you're in the front end, you retrieve the data you want to display by using a snippet tag where you want to show it. The snippet tag will be replaced by whatever string the snippet returns. Often, people use a TPL chunk with placeholder tags:



Then, in the snippet, you create an associative array of placeholder names and values and call $modx->getChunk():



The returned result will be the content of the chunk with all the placeholders replaced with the values in the $fields array.

If you're in the Manager, it's a little more complicated. You'd have to use a Custom Manager Page (CMP), or MIGX.

Thanks for the help Bob. I go try some!
