PHP/Javascript/HTML Geographical Placename Integration Tutorial

Here is a tutorial that presents various functionality via placename lookups of Latitude and Longitude. The inhouse functionality was applied in a centralized way when we did PHP/Javascript/HTML Geographicals By Placename Tutorial but for this tutorial, as promised, we add individual forms of the functionality to each of that “parent” application “child” functions in Sun Angles, Moon Angles and Great Circle Distances so that they can also sit independently of their parents with their own geographical placename dropdowns included. Am hoping it can give some pointers to ideas to do with supervision and automation, in that you can have an idea that works well (which is very important) but is not so user-friendly. Sometimes in this scenario a supervisory layer can improve things and make the application easier to use. Asking the question “What would make this easier to use?” is a good thing to step back and ask after you have created an application. And, of course, with all things, there is the “why”? Doing that here made me realise what was needed to improve the application was a data source that linked geographicals to placenames.

The Javascript embellishments in this tutorial mainly revolve around:

The use of window.open can sometimes be blocked by web browsers depending on their settings and you can read a bit more about such issues here.

Useful tutorials that helped, and we give thanks to, were:

Here is a new link to some downloadable PHP “independent child” programming source code which you may want to rename to distance.php

Here is a new link to some downloadable PHP “child” programming source code which you may want to rename to distance_lessold.php

Here is an old link to some downloadable PHP programming source code which you may want to rename to distance_old.php (for comparison purposes).

Here is a new link to some downloadable PHP “independent child” programming source code which you may want to rename to sun_angle_now_at.php

Here is a new link to some downloadable PHP “child” programming source code which you may want to rename to sun_angle_now_at_lessold.php

Here is an old link to some downloadable PHP programming source code which you may want to rename to sun_angle_now_at_old.php (for comparison purposes).

Here is a new link to some downloadable PHP “independent child” programming source code which you may want to rename to moon_angle_now_at.php

Here is a new link to some downloadable PHP “child” programming source code which you may want to rename to moon_angle_now_at_lessold.php

Here is an old link to some downloadable PHP programming source code which you may want to rename to moon_angle_now_at_old.php (for comparison purposes).

Live link to “independent child” Distance application.

Live link to “independent child” Sun Angle application.

Live link to “independent child” Moon Angle application.

These new “independent child” applications still work with the link to a live run of that “parent” supervisory application.

Did you know (PHP-wise)?

if ( basename(__FILE__) == basename($_SERVER[“SCRIPT_FILENAME”]) ) {
echo “This will only happen when called directly, not when used with require_once nor include_once”;
}

If this was interesting you may be interested in this too.
