On my forum (made in WordPress) I let users add copy to clipboard buttons so they can make code easier to copy. I am using a plugin for this meaning that when you are posting something on the forum and type this then it will make a copy to clipboard button:
[pw-clippy caption="Copy"]Text to Copy goes here[/pw-clippy]
I don't really like users having to use the name of the plugin 'pw-clippy' when making these buttons so I am wondering if I can shorten it so instead you type something like:
[copytoclip caption="Copy"]Text to Copy goes here[/copytoclip]
or this would also be fine:
[copytoclip]Text to Copy goes here[/copytoclip]
This may have an easy solution but I am fairly new to WordPress and would like to learn more.
Thanks for any help.
Note: I am not sure if it is called shortcode but any knowledge on it would be appreciated :D
Untested but here goes:
function copytoclip_shortcode( $atts, $content = null ){
return do_shortcode('[pw-clippy caption="Copy"]' . $content . '[/pw-clippy]');
}
add_shortcode( 'copytoclip', 'copytoclip_shortcode' );
Add this to functions.php, or even better as a standalone plugin file in your wp-content/plugins/ directory.

I created a new field in the editor where my colleagues can fill in a URL relevant to that specific page. This URL will be used in the button we load on every single job listing page. This button is created within the functions.php file:
function my_editor_content( $content ) {
$content = "<h3>Title</h3><p>text</P>
<a href='[acf field='afas_url']' target='_blank' rel='noopener'><button>Solliciteer Nu</button></a>";
The above is cut off at the 'afas_url' part. So, I think it has something to do with the quotations marks and probably not even hard to fix, but as I'm just starting to figure things out I couldn't find the answer myself yet.
I hope it's a clear enough explanation :)
(And maybe it's not best practice to use functions.php but it was already like this)
so we are making a wordpress site that automatically adds a link to a comment every time a comment is created. The theme we are using is html5 blank. I have written several lines of code into its function.php. however it is not working right now, here is what i wrote:
function bo_wrap_comment_text($content) {
$content = get_comment_text();
$texta = urlencode(get_comment_text());
$textb = "http://www.google.com/search?btnI&q=" + $texta;
return ''.$content.'';
}
add_filter('wp_insert_comment','bo_wrap_comment_text',1000);
a separate code(this one works) is tested here: http://phpfiddle.org and the code is:
<?php
$texta='i hate apple';
$textb=urlencode($texta);
$textc= "http://www.google.com/search?btnI&q=".$textb;
echo ''.$texta.'';
?>
the wordpress site is here. It is simply a static front page. the title you see there is the title of comment area. everything related with blog posts has been hidden using css. we have manually added links to several comments as prototyping. what we want is replace manual work with wordpress functions. I would really appreciate any help.
You need this hook instead to edit comment data:

I'm at an early stage of learning Wordpress (and shortcode), so bear with me:
To me, shortcodes seem like a swiss army knife of not having to use page-specific templates for everything. I like to build as many pages in the wysiwyg as possible, but often I would need some (reusable) php stuff for displaying stuff in a certain way.
Having googled a lot, it seems to me the way to do shortcodes is like:
function caption_shortcode( $atts, $content = null ) {
return '<span class="caption">' . $content . '</span>';
}
My question is, is it possible to put the html in a separate template-ish file? It seems wrong and verbose to put all this markup here, escape quotes, et.c. Like a template-file for a shortcode, to which the shortcode can pass some Data Transfer Object (or simply just some scoped variables). So: display in template-file, logic for finding data (to pass to said template-file) in shortcode-function (wherever it may be defined, functions.php, separate plugin, or something).
You can set-up views(php files) and then include partial views into those ones. Wordpress allows templates to be includes within other templates to ensure code reuse and its easily modifiable by child themes. You can use this function to include those
get_template_part( $slug );
However, in your case, the short code function needs to return the value to the caller function. So, this setup will not work.
For code that effects FUNCTIONALITY, put your code in a plugin.
For APPEARANCE, put your code in your theme's template files or funtions.php file.
Many beggining WP developers lump all their code into the theme's functions.php file, this is often the wrong place for it (if that code might ever get exported to another theme, for instance). Only put code specific to a specific theme in a theme's functions.php .
To get Wordpress to recognize your plugin, create a php file and start the file like this:
<?php
/*
Plugin Name: My Caption Shortcode Plugin
Description: A really cool plugin
*/
function caption_shortcode( $atts, $content = null ) {
return '<span class="caption">' . $content . '</span>';
}
?>
Put this file in your plugins directory (usually, you should create a sub directory for each plugin). Plugins are usually held in /wp-content/plugins/ . Then you can activate or deactive the code as a plugin, when you go to the plugins tab in the admin menu.
Of course, this plugin won't do anything as is. Remember that plugin functionality should be hooked into Wordpress via action hooks, filters, and shortcodes. For a shortcode for instance, you'd use the function add_shortcode somewhere to let Wordpress know your function is a shortcode.
How can I place a default text (hashtag) in the Custom Message?
The textarea is (located in line 643) under jetpack/modules/publicize/ui.php
I tried to put the text in front of $title in various ways, like:
<?php echo "#myhashtag $title"; ?>
or
<?php echo '#myhashtag '.$title; ?>
but it just echoes the text, not the $title.
Any ideas will be greatly appreciated.
You can use the approach of this Wordpress plugin i made (Publicize With Hashtags), which does exactly that. It basically use and action trigger bound to the 'save_post' native event.
If you want to develop your own one you can have a look at my Source Code on the project's GitHub page or in this installation & usage guide I wrote about it.
You can add a filter, like so, to your theme's functions.php or a site-specific plugin:
add_filter( 'wpas_default_prefix', 'add_default_publicize_hashtag_prefix', 10, 4 );
function add_default_publicize_hashtag_prefix() {
$default_tags = '#yourhastaghere ';
return $default_tags;
}
This will add your default hashtag before your title without you needing to hack the WordPress core.
jetpack/modules/publicize/ui.php itself states in its comments:
/**
* Only user facing pieces of Publicize are found here.
*/
You added your hashtag in the textarea which allows admins to enter a custom message (click edit and it will slide down with your hashtag).
As #Yazmin mentioned, the best way to permanently edit the message is using a filter. The filters available are wpas_default_prefix, wpas_default_message, and wpas_default_suffix.
Personally, I had no success using these filters and I'm interested in a working solution to this issue myself.
I am working on a wordpress site and would like to clarify a basic concept that is definitely very important, and this is how to customize/extend a wordpress hook (at least that's what I think I want to do!)
As the real world example, I am setting up a wp-ecommerce site. When a user adds an item to the cart, I would like to do one or two more things than the original function does. Looking through the source, I find:
/wp-content/plugins/wp-e-commerce/wpsc-includes/ajax.functions.php
with the function:
function wpsc_add_to_cart()
I know I could simply edit the code right here, but obviously that is the completely wrong way to go about it as when the plugin is updated, I will lose changes. What is the correct way to extend a function that is part of a plugin, or wordpress for that matter?
Endless thanks in advance.
You can use the wordpress action hooks to resolve the code loss while plugin upgrade.
You can remove the function which is in plugin file by using remove_action hook and do your own code by adding add_action in your function.php file. So that you can customize your plugin code from theme's function.php.
Here are the examples to explain.I hope it will help.

I use a little supressed notice function (it lives in my child themes function.php page), for plugins that get irritating eg: please setup twitter account to use , this kind of warning is not useful at certain stages and sometimes just do not care for it.
function supressed_notices_active(){
echo '<div class="error"><p>Supressed Notices are active</p></div>';
}
if(function_exists('the_plugin_custom_function_call')){
remove_action('the_plugin_custom_function_call' );
add_action('admin_notices','supressed_notices_active');
}else{
function test_message_from_me(){
echo '<h1>show</h1>';
}
add_action('admin_notices','test_message_from_me');
}
So I create the supressed notice function to at least create a warning, so i remember.
Check if the target function exists with the function_exists($target_function) hook
then remove this action from running with the remove_action($tag,$target_function) hook
then just add your custom function with the add_action($tag,$target_function) hook (do not need to have a separate function this could just be a closure)
then else if the function does not exist either still run a new action or leave this section, it can be useful for testing to just add anything so you atleast get some feed back.
What you could try... Copy the function within the plugin file,
paste it into your themes functions.php file,
ie:
function wpsc_add_to_cart() {
global $wpdb, $wpsc_cart;
// default values etc..etc..
// new code here?
}
the only thing with this is, if the plugin is updated and that funciton is renamed or removed, changed or something you could start to run into trouble...
could you not ask the plugin developer to possibly add your requirements to it,
possibly for a small fee? but if your using it as your main shopping cart, then chances are, that small investment could be a good thing.
