The perfect half about WordPress is plugins. Theme designers additionally generally tend of utilizing WordPress plugins for including cool options. When engaged on a customized WordPress theme mission for a shopper, one factor you wish to be sure is observe the most effective follow. Yesterday, we received an inquiry from one in all our customers whose web site was damaged. He had a customized design performed by somebody. The theme labored nice till he modified hosts. His single posts wouldn't load after put up content material. The feedback space, sidebar, footer, nothing will load. It should merely output the error. We went in and stuck the problem for them. The problem was that his theme designer didn't observe the most effective follow. He had a extremely popular plugin “Person Photograph” which lets you add user’s photo at the bottom of the post, besides he was simply including the operate instantly. Now this is able to work except ofcourse the plugin will get disabled for some motive. When this shopper switched hosts, apparently the GD Library was not put in within the new server. This precipitated the plugin to deactivate. You additionally couldn't re-activate the plugin as a result of it depends on the GD Library. This precipitated the positioning to be damaged for all customers. This clearly will get that theme designer a nasty status as a result of when the shopper requested what was the problem, we defined to them. If you're a theme designer including plugin outputs, you must at all times observe the most effective follow. Listed here are some examples of how we do issues with our shoppers:
For the favored Person Photograph plugin, we've it like this:
<?php
if( function_exists('userphoto') && userphoto_exists($author->ID))
userphoto($author->ID);
else
echo get_avatar($author->ID);
?>
The code above checks for 2 issues. It checks if the ‘userphoto’ operate exists (principally if the plugin is energetic). The second examine is to see if the person photograph exists for the particular creator. If each checks return true, then we show the userphoto. In any other case we merely have it displaying the person’s Gravatar.
For different plugins, which we do not need an alternative choice to, we at all times add a bit notice. For instance once we add OIO Writer output:
<?php if(function_exists('oiopub_banner_zone')) else
?>
The code above principally see if OIO Writer Banner Zone operate exists (which it can except the plugin is deactivated). If it does exist, then it can output the banner. If it doesn’t exist, then it exhibits the textual content to let the positioning proprietor know that this plugin has been deactivated.
If you don't add the function_exists, then your web site will return an error the place the operate fails. Theme designers please begin doing this.
