Im trying to pull the settings from Woocommerce admin. I found this:
http://oik-plugins.eu/woocommerce-a2z/oik_api/woocommerce_settings_get_option/
$string = woocommerce_settings_get_option( $option_name, $default );
It looks to be a public function but I cannot access from my theme files. It just gives me Fatal error: Call to undefined. Anyone have any idea how you can access the setting from the theme?
I'm trying to get 'woocommerce_frontend_css_primary', $colors['primary'] so can tie them into the rest of the theme. Woocommerce currently just write the values directly to .less file.
Woocommerce docs are a bit misleading, but it turns out there is another function called get_option... as long as you know the name of the option you can use. EG. get array of front end colors:
$woo_styles = get_option( 'woocommerce_frontend_css_colors' );

I am using code mirror editor from wordpress bundle in a plugin page. I have enqueued the following styles and scripts as per some research here.
wp_enqueue_style('wp-codemirror');
$cm_settings['codeEditor'] = wp_enqueue_code_editor(array('type' => 'text/css'));
$var = array(
'cm_settings' => $cm_settings
);
wp_localize_script('my-admin-script', 'my_var', $var);
Then in my js file, i have added the following line to make the textarea my_textarea to code editor.
wp.codeEditor.initialize($('#my_textarea'), my_var.cm_settings);
Everything works fine. I am not able to get value from the code mirror editor. I tried
var editor = CodeMirror.fromTextArea(document.getElementById("my_textarea"));
console.log(editor.getValue());
But i am getting an error saying CodeMirror.fromTextArea is not a function. I have been stuck at this the whole day. Any helps are appreciated.
The issue was solved on setting a variable,
var editor = wp.codeEditor.initialize($('#my_textarea'), my_var.cm_settings);
and accessing the varibale editor, you can do anything.
for eg: you can use editor.codemirror.getValue() to access the value. You don't need to use CodeMirror.fromTextArea here.
I'm using the unyson Framework for WordPress and currently using page options which work just fine on that particular page.
But I want to be able to access those options when on another page.
Here is my php -
$page = fw()->theme->get_options( 'service-settings' );
<?php echo wp_kses_post($page['service']['options']['service-box']['options']['description']; ?>
But this doesn't allow me the content from the array.
Using the following I can see the array, but cannot get the data.
fw_print($page);
Thanks guys
You're receiving just options array by calling fw()->theme->get_options('slug') - literally what you typed in the framework-customizations/theme/options/slug.php file.
If you want to receive the actual data you need to use DB helpers.
$data = fw_get_db_settings_option();
// or even refer to individual options, for performance's sake
$individual_option = fw_get_db_settings_option('option_id');
fw_print($data);
fw_print($individual_option);
I'm defining plugin path as a constant through constant define method as shown below.
define( 'MY_PLUGIN_DIR', untrailingslashit( plugin_dir_path( __FILE__ ) ) );
It is accessible within plugin all files and themes. But when I call this constant in another plugin this constant becomes undefined.
How I can get this plugin constant in another plugin? Any help will be appreciated.
Thanks,
Probably your problem is the order that wordpress is calling your plugins: the plugins that sets the constant is loaded after the one who calls it.
A better explanation of how to force your plugin be loaded first can be found here. I'm putting here a quote of the part that matters:
The order that plugins are loaded (as of WP 2.9.1 at least) is determined by the order of an array stored as "active_plugins" in the WP options table. Whenever a plugin is activated, it is added to this array, the array is sorted alphabetically by plugin name, and the array is saved to the DB.
Fortunately, there is a convenient action hook, "activated_plugins", that is called after the active plugins array is saved to the DB. This allows you to manipulate the order of the plugins stored in this array after the array is initially saved.
You'll have to the following PHP code in the plugin who defines the constant, then deactivate and reactivate it (copied from the link I providaded above).
function this_plugin_first() {
// ensure path to this file is via main wp plugin path
$wp_path_to_this_file = preg_replace('/(.*)plugins\/(.*)$/', WP_PLUGIN_DIR."/$2", __FILE__);
$this_plugin = plugin_basename(trim($wp_path_to_this_file));
$active_plugins = get_option('active_plugins');
$this_plugin_key = array_search($this_plugin, $active_plugins);
if ($this_plugin_key) { // if it's 0 it's the first plugin already, no need to continue
array_splice($active_plugins, $this_plugin_key, 1);
array_unshift($active_plugins, $this_plugin);
update_option('active_plugins', $active_plugins);
}
}
add_action("activated_plugin", "this_plugin_first");
Hope it helps!
Im very new to WordPress. I was going through Smooth Slider WP Plugin and saw
if ( function_exists( 'get_smooth_slider_category' ) ) { get_smooth_slider_category('Uncategorized'); }
This pretty much gives what I wanted, but not quite. This pulls all the content in the category and what Im after is just the image URL.
My question is whats "function_exists" in wordpress? and I checked get_smooth_slider_category in functions.php file but couldnt find any. Can someone please explain how function_exists works?
function_exists is a PHP function, not limited to WordPress.
From the manual "Checks the list of defined functions, both built-in (internal) and user-defined, for function_name."
It returns true or false on whether or not the function exists. So you can either create a new function before it that does something slightly different, or prevent an error if it doesn't exist (normally because the required file hasn't been included).
This is a PHP function that checks if the passed in name matches any defined functions (either internal, or user defined).
It is a way to check if a function is "available" before calling it.
I've created a calendar plugin and now I want to show a event list in one of my templates.
The code I'm using now, is this:
include_once(WP_CAL_PLUGIN_DIR.'eventcal.class.php');
$calendar = new EventCalendar();
$events = $calendar->getMultipleEvents('5');
(...)
<table>
<?php foreach($events as $event) : ?>
<tr>
<td><span><?php echo $calendar->formatEventTime($event->startTime,'dm'); ?></span></td>
<td><span><?php echo $calendar->formatEventTime($event->startTime,'time'); ?></span></td>
<td><?php echo $event->name; ?></td>
</tr>
<?php endforeach; ?>
</table>
Is there a way I can call functions within my plugin without having to include the WP plugin and creating a new class instance?
In order to execute shortcode inside a template, use the function do_shortcode('[my-shortcode-handle]'). Your shortcode needs to be registered as like normal (see WordPress codex on shortcode API) before you can use this in the template. Any attributes, inside content, etc. should be in there as well.
echo do_shortcode( '[my-shortcode foo="bar"]Shortcode content[/my-shortcode]' );
Also, remember to echo the return (or at least assign it to a variable), since it only returns the shortcode's output.
From: http://codex.wordpress.org/Plugin_API
Hooks are provided by WordPress to allow your plugin to 'hook into' the rest of WordPress; that is, to call functions in your plugin at specific times, and thereby set your plugin in motion. There are two kinds of hooks:
Actions: Actions are the hooks that the WordPress core launches at specific points during execution, or when specific events occur. Your plugin can specify that one or more of its PHP functions are executed at these points, using the Action API.
Filters: Filters are the hooks that WordPress launches to modify text of various types before adding it to the database or sending it to the browser screen. Your plugin can specify that one or more of its PHP functions is executed to modify specific types of text at these times, using the Filter API.
Actions
Actions are triggered by specific events that take place in WordPress, such as publishing a post, changing themes, or displaying a page of the admin panel. Your plugin can respond to the event by executing a PHP function, which might do one or more of the following:
* Modify database data
* Send an email message
* Modify what is displayed in the browser screen (admin or end-user)
The basic steps to making this happen (described in more detail below) are:
Create the PHP function that should execute when the event occurs, in your plugin file.
Hook to the action in WordPress, by calling add_action()
Put your PHP function in a plugin file, and activate it.
EXAMPLE:
function email_friends($post_ID) {
$friends = 'bob#example.org,susie#example.org';
mail($friends, "sally's blog updated",
'I just put something on my blog: http://blog.example.com');
return $post_ID;
}
Hook to WordPress
After your function is defined, the next step is to "hook" or register it with WordPress. To do this, call add_action() in the global execution space of your plugin file:
add_action ( 'hook_name', 'your_function_name', [priority], [accepted_args] );
where:
hook_name
The name of an action hook provided by WordPress, that tells what event your function should be associated with.
your_function_name
The name of the function that you want to be executed following the event specified by hook_name. This can be a standard php function, a function present in the WordPress core, or a function defined by you in the plugin file (such as 'email_friends' defined above).
priority
An optional integer argument that can be used to specify the order in which the functions associated with a particular action are executed (default: 10). Lower numbers correspond with earlier execution, and functions with the same priority are executed in the order in which they were added to the action.
accepted_args
An optional integer argument defining how many arguments your function can accept (default 1), useful because some hooks can pass more than one argument to your function. This parameter is new in release 1.5.1.
In the example above, we would put the following line in the plugin file:
add_action ( 'publish_post', 'email_friends' );
