Javascript Done Resize

by

Normally code in the resize event is meant to just run once when the user is done resizing.  This code below, from css-tricks and seen elsewhere will do the trick:


var resizeTimer;
$(window).on('resize', function(e) {
clearTimeout(resizeTimer);
resizeTimer = setTimeout(function() {
// Run code here, resizing has "stopped"
}, 250);
});

PHPUnit and PHP 7 problems

by

Problem

I’m using PHPUnit 5.5, upgraded my PHP version to 7.2.  Two problems actually occur.  First there’s this weird error:

Fatal error: Declaration of SebastianBergmann\Comparator\DOMNodeComparator::assertEquals…

Then figuring PHPUnit needs to be upgraded, I ran

phpunit –self-upgrade

And that failed with the same error.  Changing my PHP version back down to 5.6 and running then causes this error:

internal corruption of phar “…phpunit-temp.phar” (truncated entry)

 

Solution

Unfortunately PHPUnit 5.5 only supports up to version 7.1 and any old version of PHPUnit that has an “old” certificate needs to be downloaded/updated manually.

How to stop redirect from http:// to https:// in Chrome

by

Problem

I’ve been trying like crazy to get to my local website at site.dev, but I keep getting redirected to https://site.dev and of course it doesn’t work because I don’t have a SSL certificate for that domain.

Solution

As of December 2017, Chrome 63, Chrome is forcing all .dev domains to be redirected to HTTPS via a preloaded HTTP Strict Transport Security (HSTS) header.  The .dev TLD is an actual legitimate TLD so you will need to change your local development setup to use something like http://site.localhost .

A more detailed explanation can be found here:

SVG height not scaling properly on IE 10

by

Problem

IE 10 shows a skewed svg image who’s width is set to a specific value and height is auto.

 

Solution

The problem is the width and height in the SVG file is set and IE is following those specs if you don’t set it.  So if you’re image is 100×100 and you set only the width to 50px, the height will remain at 100px.  The solution is to remove the width and height attributes in the <svg> tag.

Caveats

A solution on a github gist suggests that removing the width and height attributes force the image to occupy the full width of its container in non-IE browers.  All my current images with SVG are supposed to fill the width so this isn’t a problem for me.

wpdb insert returning false

by

Problem

When running wpdb->insert the result returns false.  All the values seem to check out to be fine.

 

Solution

The problem might be due to this bug in WordPress.  Basically one of your fields is too long and WordPress is not completing the insert.  Reading through the ticket, it seems it is a WordPress error and not a MySql error so it would be pretty difficult to go through all the fields, determine the column field size limits, and then return an error of some sort.  Anyway, this is one possible reason to wpdb->insert returning false.

WP Cron with Basic Authentication

by

Problem

WordPress’ cron doesn’t work when a site has basic authentication.  You basically would get a 401 error.

 

Solution

Thanks to Nick Ohrn (in 2014) this problem is solved with a simple mu-plugin.  You just need to set the username and password in a constant in wp-config and add some code to the mu-plugins directory.  Here is his quick tip.
