![]() How could I generate a grid of valid geometries that covers the whole globe?Īs for your first problem, what would you want to happen with a point that falls exactly on the boundary between two grid cells? Throws couldn't project point (-180 90 0): latitude or longitude exceeded limits (-14) If I avoid the geography type, and use a geometry there is no global projection that outputs the correct size of all grids. Throws an error ptarray_area_spheroid: cannot handle ptarray that crosses equator e.g when I compute the square meters of a grid (for the density) SELECT ST_Area(ST_GeographyFromText('POLYGON((-15 0,-15 5,-10 5,-10 0,-15 0))')) ![]() Second, it seems the algorithm generates invalid geometries. The question is thus if there is a constant for the absolute minimum step value that I could use to guarantee that one point exactly lays next to another with no space inbetween. I could subtract a very small value from corners, but this risks loosing objects when they come to lay exactly on the original line. 180 in a fixed step size creating the multiline polygons.įirst, adjacent cells share a separating line, making objects on it counting towards two or more cells. To create the grid, I have created multiline polygons, both using a script of my own, and the function suggested here: How to create a regular polygon grid in PostGIS?. The grid is used to measure a density value by counting the number of certain spatial objects in each grid cell. I just put this in my functions.I want to create a grid spawning the whole globe. I got the media grid thumbnail working by adding a function that adds the dimensions metadata to the svg uploaded. Thank you to Sakin Shrestha for first highlighting this to me. Other times when I am not 100% sure of all the use cases I will suggest to my client to use the Safe SVG plugin.Įither way I suggest adding some documentation to your theme or plugin’s if you use it readme file to highlight the potential dangers and risks of enabling SVG upload in WordPress. If I am doing a small site that I know will only be being used by a couple of experienced users I’ll add the capability via a function a plugin or even add it straight to the functions.php. And if it’s for a client job maybe donate and show a little love to it’s developer Daryll Doyle. Although it’s not perfect by any stretch it does at least provide some security. If you do need to SVG upload support in a WordPress theme Bjørn recommends using the Safe SVG plugin. Bjørn Johansen does a much better example of explaining why in more depth here: SVG as a document format is susceptible to Cross-Site Scripting (XSS) attacks as it’s difficult to write an SVG sanitizer that prevents them. SVG has intrinsic security issues so WordPress doesn’t support SVG upload by default. If the above does not work, get a professional in to help if it’s critical I am actually unavailable, abroad 1000’s of miles from home right now, so responses could be thin on the ground ) ![]() I have tested the plugin on quite a few installs of WP, and can confirm it works for standard deploys, standard salient themed & child themed sites, striking theme & child theme sites, 2012, 2014 & 2015 themes, with akismet, google analyticator, Disqus Comment System, all my bespoke client plugins, WooCommerce, maybe some plugins I didn’t install…īasically the plugin is not very smart, it just modifies the upload types array & some code that is very shodily crammed into DOM by WP.Īlso be careful, the gist needs to be copied from GitHub, CSS-Tricks embed in the comment seems bugged (I raised an issue on it earlier). ![]() ![]() It sounds like either your theme, or one, maybe more of your plugins is causing the issue. Do me a favor, turn off all plugins, except my gist plugin, which needs to be active switch to a new vanilla theme, and don’t modify it, or core wordpress (if you changed the core, you’ll need to roll-back to a clean install, or re-install) try again. Screenshots definitely will not help you, or me (or anyone else), in resolving this buddy. ![]()
