Create a Custom Error Page for "Error establishing a database connection"

Error establishing a database connection

Here’s how to make a custom database error page for WordPress.

If your site’s all set up and you see “Error establishing a database connection,” that’s an immediate “oh crap” situation.

Hostgator.com, the company that hosts this website, has had some issues recently, and I’ve seen that screen a little too often.

If you want to define a custom “Error establishing a database connection” screen, add a file to your /wp-content/ folder named db-error.php. That will be loaded instead of that stupid message. Check out SEODenver.com’s db-error.php.

A Good Idea for SEO

If you want to prevent search engines from indexing your site while it’s down, add <meta name="robots" content="noindex, nofollow" /> to your page’s `<head>`. You sure don’t want Google caching your error! Continue reading “Create a Custom Error Page for "Error establishing a database connection"”

Generate a Link to Activate a Plugin in WordPress

Here’s another specialized plugin development tip!

If you want to create a link to activate a plugin, you need to know the path of the plugin file. Let’s use Akismet for this example.

$path = 'akismet/akismet.php';
$link = wp_nonce_url(admin_url('plugins.php?action=activate&plugin='.$path), 'activate-plugin_'.$path);

The `$link` URL will be something like http://yoursite.com/wp-admin/plugins.php?action=activate&plugin=akismet%2Fakismet.php&_wpnonce=f97dabdf9

How to Hard-Code a UA String for the Google Analytics for WordPress Plugin

If you want to define a Google Analytics “UA String” while using Yoast Google Analytics plugin for WordPress.

Add the following to your theme’s `functions.php` file:

add_filter( 'option_Yoast_Google_Analytics', 'custom_ua_string_filter');

function custom_ua_string_filter($options = array()) {
	$options['uastring'] = 'UA-########-#';
	$options['manual_uastring'] = true;
	return $options;
}

For users of WordPress Multisite, this will allow you to pre-configure new blogs with the same UA string.

Enable Shortcodes for Gravity Forms Field Descriptions

To enable shortcodes inside your Gravity Forms form description, field labels and descriptions, you need to add the following code to your theme’s functions.php file:

add_filter('gform_pre_render', 'walker_do_shortcode_gform_description', 10, 2);

function do_shortcode_gform_description(&$item, $key) {
    $item = do_shortcode($item);
}

function walker_do_shortcode_gform_description($form, $ajax) {

    $form['description'] = do_shortcode($form['description']);
    array_walk_recursive($form['fields'], 'do_shortcode_gform_description');

    return $form;
}

Merge Settings Into an Array in WordPress

Arrays Merging

I found people are coming to this site (to an unrelated article) looking for a way to merge settings into an array.

You’re looking for `wp_parse_args()`

The main function for WordPress to do this is `wp_parse_args()`. You likely want this function.

Learn more about `wp_parse_args()`

Also consider `shortcode_atts()`

This is used for parsing shortcode options. It only supports defined arguments.

Mitt Romney's Compressed Images

Mitt, don’t skimp on image optimization

I just visited Mitt Romney’s website for the first time and noticed right away that his site looked cheap because his button images had been so compressed for load time.

 

For comparison, here are some similar boxes on BarackObama.com

 

Look for yourself

I don’t think the affect of the bad quality comes across in these pictures. I encourage you to compare and contrast.

Simple Way to Get Plugin Status in WordPress

Active plugin volcano.

I have previously written on how to determine if a widget is active. This is helpful for widgets, but not for plugins.

WordPress has a couple of different functions that help you determine plugin status. They are both located in wp-includes/plugin.php

  • `validate_plugin()` spits out an error if the plugin file does not  exist or has an invalid header. This lets you know that the file is there.
  • `is_plugin_inactive()` lets you know if the plugin is not active (using the `is_plugin_active()` function)

A function to get plugin status

Using these two functions, I put together a one-size-fits-all function `get_plugin_status()`. Continue reading “Simple Way to Get Plugin Status in WordPress”

WordPress Real Estate Plugin: Stay Tuned…

You may have noticed this blog has gone un-updated. That’s because I’ve been working on an awesome new plugin.

WordPress + Real Estate + User Data + SEO

In the past, I’ve written posts about how to optimize your WordPress real estate website for SEO and I’ve created a Trulia plugin for WordPress.

This WordPress real estate plugin changes the game of what you can do with your WordPress website — and for how much money. No longer do you need to pay tens of thousands of dollars for an indexed IDX solution.

Next week I will release a beta version, so stay tuned for the formal announcement.

Easy Content Deployment for WordPress: RAMP

RAMP allows you to make all the changes you need in your staging environment, then selectively push these changes to your production site. You can set up a new section of your site, upload some images to fill out a nice carousel for it, and add a link to it on your home page. Once this content has been reviewed and approved, you can go to your RAMP page, select these content changes, and push them to your production site.

This would be really handy for larger WordPress sites.

Yourls Google Analytics Link Tagging

In my last post, I wrote about the benefits of using YOURLS, a self-hosted link-shortening service. I’m finding that YOURLS is great, but it’s not perfect. Some of the issues I have experience are part of what you get using most URL shortener services.

Some of the downsides of using link shorteners are:

  1. Google Analytics doesn’t always capture the original referrer (and I have no clue how they do the rest of the time!).
  2. When generating links using the bookmarklet (or in this case, also the Yourls installation), there’s no easy way to add campaign, source, medium, content, and term tags for Google Analytics to track.
  3. Yourls doesn’t allow query strings on URLs by default, making overriding existing campaign tags difficult/impossible. For example: `http://katz.si/t?utm_source=2300`

I’m not the only one who wanted these things, so I’ve created a plugin that adds Google Analytics tracking to Yourls. It’s very cool.

YOURLS URL Shortener

YOURLS LogoI was having trouble finding the right URL shortening service. My requests for shortening were not too picky. I wanted two simple features:

  • Good statistics that are visible only to administrators
  • Edit the long URLs after generating shortened links

…but not one service has both features:

  • http://sn.im has editable URLs, a bookmarklet, but no stats. Oh, and they kept on deleting my links.
  • http://bit.ly has great stats, name recognition, but the links aren’t editable and the stats are public.
  • http://goo.gl is the fastest service (so they claim), they have good stats (maybe the best, since they include OS & browser information), but they don’t have editable links or private stats.

Other smaller offerings may have had both features, but they also seem unreliable. I wanted control of my links. Continue reading “YOURLS URL Shortener”

The Google +1 Sprite Animation

How the +1 Button Works

Google +1 Button The +1 Button uses an advanced sprite technique to simulate an animated `gif`. The animation occurs when hovering over search results with +1 enabled, and the shine moves across the button. (The image to the right is an animated `gif` I made…)

The +1 Button is not an animated `gif`, however. It’s a sprite image that moves a background image across the “window” of the button using Javascript. The code, if you care, goes something like this:

`onmouseover=”window.gbar&&gbar.pw&&gbar.pw.hvr(this,google.time())”`

The sprite image Google uses for the +1 button is below:

Google +1 Sprite

Pretty neat, huh?

Yeah, the +1 Button animation is pretty neat…
…now turn it off!

Oh goodness gracious, the animation is annoying. After hovering over one search result, it’s obvious how awful the animation is and I want to claw my eyes out with a rusty nail. I wanted to find a way to disable the animation. Continue reading “The Google +1 Sprite Animation”

Paginate Links in WordPress Link Manager

Links are not first-class citizens in WordPress

In developing the a website for professional genealogists, I was tasked with creating link directory functionality in WordPress. I didn’t want to install some big plugins; I wanted to use the Links Manager that’s built in to every WP install out of the box. There were two problems, however:

  1. Link categories are not hierarchical, and;
  2. There is no pagination in the Links Manager: all links are displayed on one page by default.

My client’s website will have over 20,000 links; having them all on one page was simply not an option.

I didn’t want to create a new Post Type or Taxonomy; Links are already the right tool for the job. I moved forward creating the custom solution, and am sharing the results of that development here. The result of the project was a successful deployment of a crazy amount of links (see an example on their Iowa genealogy resources page). Continue reading “Paginate Links in WordPress Link Manager”
