Add a widget area to your single.php, front-page.php, home.php or whatever you want.. template’s theme file. Than at the back-end go to Appearance > Widgets and move the widget to the widget area you just created.
The Widgets API is the quickest way to make a widget that’s reusable. Example use: class My_Widget extends WP_Widget { /** * PHP4 constructor */ function My_Widget() { My_Widget::__construct(); } /** * PHP5 constructor */ function __construct() { // actual widget processes } /** * Echo the settings update form * * @param array $instance … Read more
The error isn’t actually caused by your PHP version (PHP 4 constructors won’t be removed until PHP 7) – it’s a warning produced by WordPress in preparation for this. Each repetition of the error represents a plugin using the outdated code. Until your plugins’ authors update them, you can run the following shell command on … Read more
You can get the instance ID with echo $this->id; ($this is the class instance) The only time you can’t get this id is from the form() function, right after you just dropped the widget (here‘s the reason why)
Put simply: not inherently. If you have a widget that does NOTHING at all…like, literally you add it and there’s no code for the widget outside of registering it, you’ll see SUCH a small performance hit from adding it that you would need to be looking at microtime() numbers to notice anything. That said, as … Read more
It’s hard to say without seeing all the code. Yes if you don’t refer to the instance – then it won’t really be a unique ID. Something like this would work – you would just reference the class property $id: for ( $i = 0; $i <= count( $suffixes ); $i++) { wp_editor( ‘your content’, … Read more
Danny, this is pretty much lifted straight from a plug-in I’ve made: <?php function form($instance){ $instance = wp_parse_args( (array) $instance, $this->w_arg ); ?> <p> <select id=”<?php echo $this->get_field_id(‘order’); ?>” name=”<?php echo $this->get_field_name(‘order’); ?>” type=”text”> <option value=”asc” <?php selected($instance[‘order’], ‘asc’); ?>>ASC </option> <option value=”desc” <?php selected($instance[‘order’], ‘desc’);?>>DESC </option> </select> </p> <?php } ?> Without seeing the … Read more
I’m sure there is a more elegant approach (I’d love to know about!). Anyhow: I’d like to offer a solution. You could create a default sidebar with default widgets and a custom sidebar with all available custom widgets. Then you use a combination of the following plugins: simple fields and widget logic to only show … Read more
The solution I can think of is removing the panels Available and Inactive Widgets so there’s simply nowhere to drag (and delete) the widgets used in the sidebar. You can inject something else to fill the gap. In this example, only one user is able to add/delete widgets. function wpse_53398_script_printer(){ // used to display the … Read more
It’s a bit unwieldy to just grab all posts by an author and filter through them to only return a category list. If you wish to use the default widgets in the sidebar and have them filtered by the author only on the author template then I’d suggest using the following approach. First, filter the … Read more
