I want to see if him doing this code correctly to developed a custom shortcode for contact form want to create for my website.
I have looked at wp codex want to use class so I came up with this code to if this would work.
<?php
class MyPlugin {
// Conact Form shortcode
public static function allb_contact_form( $atts, $content = " " ) {
//[contact_form]
//get the attribute_escape
$atts = shortcode_atts(
array(),
$atts,
'contact_form'
);
//return HTML
ob_start();
include 'lib/inc/thmeplates/contact-form.php';
return ob_get_clean();
}
}
add_shortcode( 'contact_form', array( $this , 'allb_contact_form' ) );
But it doesn't give me error messages that says. One guy told me to put the add_shortcode( 'contact_form', array( $this , 'allb_contact_form' ) ); at the outside of code.
If you are intent on using a class, wherever you are declaring your plugin add
$myplugin = new MyPlugin();
add_shortcode( 'contact_form', [ $myplugin , 'allb_contact_form' ] );
And remove that add_shortcode from the class. It's not even valid code laying there.

I have a few .html and .php pages in my custom wordpress plugin directory/files that I'm using to output styles JSON/jQuery data basically.
I am wondering how I could essentially wrap these modules in a short code and insert that short code in my Wordpress posts or pages via the Wordpress wysiwyg editor. i.e. [module 1]. I do not want to do this in the theme's files or /functions.php I want to add this functionality from my plugin files, any thoughts?
So, like a php include in the form of a wordpress short code, that works in Wordpress pages.
Here is what I'm trying; within my main plugin php file:
function my_form_shortcode() {
include dirname( __FILE__ ) . 'https://absolute.path.com/wp-content/plugins/my-plugin-v4/assets/files/2019/results/index.php';
}
add_shortcode( 'my_form_shortcode', 'my_form_shortcode' );
Within my Wordpress page, I do: (although, does not display/work)
[my_form_shortcode]
You can add your shortcode function the same way you would in your theme
add shortcode function in plugin
Simplest example of a shortcode tag using the API: [footag foo="bar"]
function footag_func( $atts ) {
return "foo = {$atts['foo']}";
}
add_shortcode( 'footag', 'footag_func' );
Example with nice attribute defaults: [bartag foo="bar"]
function bartag_func( $atts ) {
$atts = shortcode_atts( array(
'foo' => 'no foo',
'baz' => 'default baz'
), $atts, 'bartag' );
return "foo = {$atts['foo']}";
}
add_shortcode( 'bartag', 'bartag_func' );
Example with enclosed content: [baztag]content[/baztag]
function baztag_func( $atts, $content = "" ) {
return "content = $content";
}
add_shortcode( 'baztag', 'baztag_func' );
If your plugin is designed as a class write as follows:
class MyPlugin {
public static function baztag_func( $atts, $content = "" ) {
return "content = $content";
}
}
add_shortcode( 'baztag', array( 'MyPlugin', 'baztag_func' ) );
I am trying to echo visual composer shortcodes onto a page.
I've tried both methods below, but they don't work:
functions.php:
Method 1
/*
* add shortcode file
*/
function include_file($atts) {
$a = shortcode_atts( array(
'slug' => 'NULL',
), $atts );
if($slug != 'NULL'){
ob_start();
get_template_part($a['slug']);
return ob_get_clean();
}
}
add_shortcode('include', 'include_file');
Method 2
function someshortocode_callback( $atts = array(), $content = null ) {
$output = "[vc_section full_width=\"stretch_row\" css=\".vc_custom_1499155244783{padding-top: 8vh !important;padding-bottom: 5vh !important;background-color: #f7f7f7 !important;}\"][vc_row 0=\"\"][vc_column offset=\"vc_col-lg-offset-3 vc_col-lg-6 vc_col-md-offset-3 vc_col-md-6\"][/vc_column][/vc_row][/vc_section]";
return $output;
}
add_shortcode('someshortocode', 'someshortocode_callback');
file_rendering_vc_shortcodes.php:
Method 1
<?php if ( is_plugin_active( 'js_composer/js_composer.php' ) ) {
wc_print_notice('js_composer plugin ACTIVE', 'notice');
echo do_shortcode('[include slug="vc_templates/shop-page"]');
}; ?>
Result
js_composer plugin ACTIVE
shortcode is on page with parentheses as is
Method 2
<?php $post = get_post();
if ( $post && preg_match( '/vc_row/', $post->post_content ) ) {
// Visual composer works on current page/post
wc_print_notice('VC ON', 'notice');
echo add_shortcode('someshortocode', 'someshortocode_callback');
} else {
wc_print_notice('VC OFF', 'notice');
//echo do_shortcode('[include slug="vc_templates/shop-page"]');
}; ?>
Result
VC OFF (obviously, since the vc_row in shortcode is not there)
shortcode is NOT on page
shop-page.php
<?php
/**
Template Name: Shop Page in theme
Preview Image: #
Descriptions: #
* [vc_row][vc_column][/vc_column][/vc_row]
*/
?>
[vc_section full_width="stretch_row" css=".vc_custom_1499155244783{padding-top: 8vh !important;padding-bottom: 5vh !important;background-color: #f7f7f7 !important;}"][vc_row 0=""][vc_column offset="vc_col-lg-offset-3 vc_col-lg-6 vc_col-md-offset-3 vc_col-md-6"][/vc_column][/vc_row][/vc_section]
Is it possible to render vc shortcodes on page, and if so, how is it done?
Use the:
WPBMap::addAllMappedShortcodes();
then as usual do_shortcode($content);
In short, page builder due to performance doesn't register shortcodes unless it isn't required.
If your element is registered by vc_map or vc_lean_map then no need to use add_shortcode function, you can do everything just by using WPBMap::addAllMappedShortcodes(); it is will call an shortcode class callback during the rendering process and then shortcode template.
Regarding Method 2.
You have to use do_shortcode() in your shortcode function.
function someshortocode_callback( $atts = array(), $content = null ) {
$output = '[vc_section full_width="stretch_row" css=".vc_custom_1499155244783{padding-top: 8vh !important;padding-bottom: 5vh !important;background-color: #f7f7f7 !important;}"][vc_row 0=""][vc_column offset="vc_col-lg-offset-3 vc_col-lg-6 vc_col-md-offset-3 vc_col-md-6"]column text[/vc_column][/vc_row][/vc_section]';
return do_shortcode( $output );
}
add_shortcode( 'someshortocode', 'someshortocode_callback' );
Working example on my test site: http://test.kagg.eu/46083958-2/
Page contains only [someshortocode]. Code above is added to functions.php.
In your code for Method 2 there is another error: line
echo add_shortcode('someshortocode', 'someshortocode_callback');
cannot work, as add_shortcode() returns nothing. This code should be as follows:
<?php $post = get_post();
if ( $post && preg_match( '/vc_row/', $post->post_content ) ) {
// Visual composer works on current page/post
wc_print_notice('VC ON', 'notice');
} else {
wc_print_notice('VC OFF', 'notice');
add_shortcode('someshortocode', 'someshortocode_callback');
echo do_shortcode('[someshortocode]');
}; ?>
The following is the shortcode I created in functions.php:
function echo_first_name() {
echo $_GET['first_name'];
}
add_shortcode( 'first_name', 'echo_first_name' );
And I'm entering the following into my Visual Composer editor:
['first_name']
This produces no result, even when using the Visual Composer shortcode mapper.
Does anybody know why this isn't working? Do I have to register it as another type of shortcode for Visual Composer to be able to access it?
For Create Short code
if you want to add short code in editor then Used return instead of echo
function echo_first_name() {
return $_GET['first_name'];
}
add_shortcode( 'first_name', 'echo_first_name' );
Used Short Code Like
[first_name]
If you want to pass the value In shortcode
function echo_first_name( $atts ) {
$a = shortcode_atts( array(
'firstname' => '',
), $atts );
return "First Name= {$a['firstname']}";
}
add_shortcode( 'first_name', 'echo_first_name' );
Used Short Code Like
[first_name firstname="test"]
You are passing a $_GET['firstname'] in the shortcode function from where you are passing this in URL or from any other place. Please check it is coming or not.
Or if you want to test your shortcode is working or not use beloww code it will work.
function echo_first_name() {
return 'testing the shortcode';
}
add_shortcode( 'first_name', 'echo_first_name' );
Use return instead of echo
function echo_first_name(){
return $_GET['first_name'];
}
add_shortcode( 'first_name', 'echo_first_name' );
I have a review plugin that overrides the comment form in a specific posttype.
Now I'm trying to seperate the reviews and comments.
My first step is to remove the filter that modifies the current comment template and use that filter inside a second comment form.
The plugin uses this code (simplified)
final class DM_Reviews {
public function hooks() {
do_action_ref_array( 'dm_reviews_before_setup_actions', array( &$this ) );
add_filter( 'comment_form_defaults', array( $this, 'reviews_form' ) );
do_action_ref_array( 'dm_reviews_after_setup_actions', array( &$this ) );
}
public function review_form( $args ) {
$form = 'plugin code to modify form';
return wp_parse_args( $form, $args );
}
}
In my child theme's function.php file, I tried to use this but it didn't worked.
global $DM_Reviews;
remove_filter( 'comment_form_defaults', array($DM_Reviews, 'reviews_form'),1 );
WP Codex
If someone can put me in the right direction on how to solve it, it would help me a lot.
I think you can achieve this goal, using one of the following solutions depending on the way this plugin instantiates the class:
if( class_exists('DM_Reviews' ) ){
//This should work in whatever case, not tested
remove_filter('comment_form_defaults', array( 'DM_Reviews', 'reviews_form'));
//or Instantiating a new instance, not tested
remove_filter('comment_form_defaults', array( new DM_Reviews(), 'reviews_form'));
//or Targeting the specific instance, not tested
remove_filter('comment_form_defaults', array( DM_Reviews::get_instance(), 'reviews_form'));
}
Hope it helps, let me know if you get stuck.
for me remove_filter didn't work from function.php i wanted to remove a specific behavior of a plugin so what i did :
add_action( 'init', 'remove_filters' );
function remove_filters(){
global $wp_filter;
unset( $wp_filter["_filter_name"]);
}
Try this :
$instance = DM_Reviews::this();
remove_filter('comment_form_defaults', array( $instance, 'reviews_form'));
I'm trying to use a widget within a plugin in wordpress and I'm seeing this error within the widget box:
Warning: extract() [function.extract]: First argument should be an array in /nfs/c03/h04/mnt/57957/domains/rab.qbessi.com/html/wp-content/plugins/register-plus/dash_widget.php on line 24
This is the code from Line 24:
// Output the widget contents
function widget( $args ) {
extract( $args, EXTR_SKIP );
Here's the dash_widget.php code
<?php
if( !class_exists('RegisterPlusWidget') ){
class RegisterPlusWidget{
function RegisterPlusWidget() { //contructor
// Add the widget to the dashboard
add_action( 'wp_dashboard_setup', array($this, 'register_widget') );
add_filter( 'wp_dashboard_widgets', array($this, 'add_widget') );
}
function register_widget() {
wp_register_sidebar_widget( 'regplus_invite_tracking', __( 'Invitation Code Tracking', 'regplus' ), array($this, 'widget'), array( 'settings' => 'options-general.php?page=register-plus' ) );
}
// Modifies the array of dashboard widgets and adds this plugin's
function add_widget( $widgets ) {
global $wp_registered_widgets;
if ( !isset($wp_registered_widgets['regplus_invite_tracking']) ) return $widgets;
array_splice( $widgets, 2, 0, 'regplus_invite_tracking' );
return $widgets;
}
// Output the widget contents
function widget( $args ) {
extract( $args, EXTR_SKIP );
echo $before_widget;
echo $before_title;
echo $widget_name;
echo $after_title;
global $wpdb;
$regplus = get_option( 'register_plus' );
$codes = $regplus['codepass'];
$usercodes = array();
foreach($codes as $code){
$users = $wpdb->get_results( "SELECT user_id FROM $wpdb->usermeta WHERE meta_key='invite_code' AND meta_value='$code'" );
echo '<h3>' . $code . ': <small style="font-weight:normal">' . count($users) . ' Users Registered.</small></h3>';
}
echo $after_widget;
}
}
} # End Class RegisterPlusWidget
// Start this plugin once all other plugins are fully loaded
add_action( 'plugins_loaded', create_function( '', 'global $regplus_widget; $regplus_widget = new RegisterPlusWidget();' ) );
?>
The widget() function is being called with no parameters. Why, is hard to tell without digging deeply into the plugin. You should ask the plugin's author.
You can try adding
// Output the widget contents
function widget( $args ) {
if (is_array($args)) // Add this
extract( $args, EXTR_SKIP );
and see whether the output still makes sense then. That effectively just suppresses the action that causes the warning. If it's a badly programmed plugin that was developed with warnings turned off, that already may do the trick.
