After digging internet for an answer I cannot find any idea about how to deal with my issue. I think the problem is common for someone who knows PHP a little bit.
To describe the situation. For some custom WordPress plugin I've got two PHP files: ff_config.php and loantest_form.php. First file contains some configurations of plugin plus following lines:
/**--------------------------TABLE SHORTCODES-----------------------*/
function render_loantest_form() {
include(plugin_dir_path(__FILE__) . 'front/loantest_form.php');
}
add_shortcode( 'render_loantest_form' , render_loantest_form );
/**--------------------------DISPLAY PLUGIN IN FOOTER-----------------------*/
add_action('wp_footer', 'display_loantest');
function display_loantest() {
echo render_loantest_form();
}
Which I suppose rendering second file containing enqueue scripts (js/css) and whole HTML output and placing in wp_footer where it exactly is on my page.
The question is: how to change mentioned lines to allow me to place render result (loantest_form.php) in specific div / id on page (for example #sidebar-slider)?
If you want to display your shortcode in a template file,
echo do_shortcode('[render_loantest_form]');
Enable the use of shortcodes in text widgets.
add_filter( 'widget_text', 'do_shortcode' );
And inside the text editor
[render_loantest_form]
You can read more about do_shortcode()
Note that you need to be sure that the file load in the render function is good and that it returns the expect content.

I'm working on a Wordpress theme, where I want to change the generated markup of the [product_category] WooCommerce shortcode. I browsed through the templates directory in the plugin, but can't find the file related to this particular shortcode.
So my question is, which files I have to copy to my template and modify to change the HTML outcome of [product_category]? (CSS modifications are already done, but I need to display a very different HTML markup, and I don't want to hack around with JS).
Also it would be better not to rewrite the whole function with a hook, but change the original HTML a bit (for example, set the background color based on a custom meta field).
Esiest way :)
add_shortcode('test','test_show_shortcode');
function test_show_shortcode( $atts ) {
echo do_shortcode('[products limit="100" columns="..." category="..."]');
}

In pure theory my question is whether it is possible to make one php function run twice taking a different variable each time and returning it as a result.
In practice, I'm tinkering with a child theme for WordPress (and learning some PHP basics). The original theme, twentysixteen, has a function to construct a link to Google fonts using several parameters and output the final URL, which is then taken by some other function and inserted in to the head template with added HTML markup - link, href, rel, type.
In my child theme I had to replace one of the default fonts completely, so instead of reconstructing the function, I simply minimized it to just contain and output the final font URL like so:
if ( ! function_exists( 'twentysixteen_fonts_url' ) ) :
function twentysixteen_fonts_url() {
$fonts_url = 'https://fonts.googleapis.com/css?family=Merriweather:400,700,900,400italic,700italic,900italic|Inconsolata&subset=latin,latin-ext,cyrillic,greek';
return $fonts_url;
}
endif;
What I'm trying to do now is get another URL (https://code.cdn.mozilla.net/fonts/fira.css) into this function to load a third font from Mozilla's CDN alongside the Google ones.
Can't put it into a separate function with a different name, because its output does not get picked up by the head template. Using an array puts both urls into one link href.
Can somebody please point me in the right direction?
Thank you.
Twentysixtee juste use one font, and the URL is generated with twentysixteen_fonts_url ()
If you look into Twentysixtee's function.php, twentysixteen_fonts_url () is use only 2 times. It's use to include font url in editor (line 144) and in front end (line 233).
Add an other font
If you want to add an other font you need to add it in your child theme.
You could do it by adding the following code in your function.php
function my_child_theme_font_url()
{
$fonts_url = 'https://code.cdn.mozilla.net/fonts/fira.css';
return $fonts_url;
}
function my_child_theme_enqueue_scripts()
{
wp_enqueue_style( 'my_child_font', my_child_theme_font_url(), array(), null );
}
add_action( 'wp_enqueue_scripts', 'my_child_theme_enqueue_scripts' );
As suggested by #MonkeyZeus the simplest way to achieve having another webfont enqueued in such cases is leaving the first function as it is and adding a different one right after it to enqueue the needed file like so:
add_action( 'wp_enqueue_scripts', 'register_custom_plugin_styles' );
function register_custom_plugin_styles() {
wp_register_style( 'fira', 'https://code.cdn.mozilla.net/fonts/fira.css' );
wp_enqueue_style( 'fira' );
}
As for the theoretical part of my question, I understand that somehow forcing a function to run a second time and produce a different output would not force the other function using this output to run a second time as well, producing a different result. For this to work, the calling function has to be modified, not the emitting one.
Thank you #MonkeyZeus and #Jordane-CURE for your help.
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've written a plugin which shortcodes can easily be used in every post and page. As this plugin can be useful in a sidebar as well i want to make the text widget usable for my shortcodes.
When i googled this i found out that i can use the add_filter() function to ensure that, but this is only possible if i have access to the theme's functions.php. But as i am the creator of the plugin and not of the theme, this is not usable for me.
Does anybody know how i can make a shortcode which is introduced with a plugin usable in the widgets section?
Thanks!
Open your theme's function file.
Find a free spot after the opening php tag that isn't part of a function.
add this:
if (!is_admin())
{
add_filter('widget_text', 'do_shortcode', 11);
}
save the file and you should be all set.
Open your page in edit mode.
Select your page location and line where you want to add short code.
Add code here and update..
