Plugin depend to woocommerce plugin.
When in else part Remove Start PHP and End PHP then work but How to print message of notice.
Suggest me.
Thanks.
Your plugin shouldn't output or echo anything by itself, and should instead use hooks to manipulate content.
If you do so, and still have the error
Plugin generated X lines of unexpected output during activation
you can install this to see what was the output of the plugin.

I'm hoping someone can clue me in on how I can extract a plugin value and display it on my page using a short code. Specifically, when a user reaches the max allowable limit, I would like a notification message to appear on the page (in addition to its placement in a popup) Many tests and I have not been able to get this to work. MANY thanks in advance.
public function add_error_limit_message() {
if ( ! $this->limit_reached ) {
return;
}
$message = apply_filters( 'woocompare_limit_reached_message', __( 'You have reached the maximum number of products for compare table.', 'woocommerce-compare' ) );
echo '<div class="woocompare-error"><p>' . wp_kses_post( $message ) . '</p></div>';
}
add_shortcode( 'limit-reached-message', 'add_error_limit_message' );
Your shortcode function should return the text string you want to insert in place of the shortcode, not echo it.
To track down "critical errors" (php errors) turn on WP_DEBUG and WP_DEBUG_DISPLAY in your wp-config.php file. And try installing and activating the Query Monitor plugin. These will tell you enough about your php errors to track them down and fix them.
I have developed my own wordpress theme, and learning all kinds of programming stuff, but my priority is the content, not the programming knownledge. I need to know how to remove archive date listing from wordpress?
Question 1: The google search results displayed like this: virmodrosti.com/2017/05/
I don't want any kind of date archive option, how do you disable that?
I also don't use any kind of plugin, and always like to do it on my own.
Question 2: I don't know why older entries doesn't work anymore
virmodrosti.com/zdravje/ this page works fine
virmodrosti.com/zdravje/page/2/ it redirects to 404 error page
I only choose option in wordpress to hide that annoying /category/ with dash . inside editor at permanlinks, Category base. Maybe somehow these stuff is kinda fighting with each other and doesn't work properly.
Thank you.
This is code from Digital Nomad theme I maintain:
function digitalnomad_remove_date_archives() {
//if we are on date archive page
if ( is_date() ) {
// theme sets alternatine archive page with table like list of all posts
$archive_page = get_option( 'digitalnomad_archive_page' );
if ( $archive_page ) {
// redirs to alternatine archive page if configured (good for SEO)
wp_redirect( esc_url( get_page_link( $archive_page ) ) );
die();
} else {
// otherwise error 404 is displayed
global $wp_query;
$wp_query->set_404();
}
}
}
add_action( 'template_redirect', 'digitalnomad_remove_date_archives' );
Use the smart Archive Page Remover wordpress plugin
or visit your theme's functions.php file
then insert this code
/* Register template redirect action callback */
add_action('template_redirect','makes_remove_wp_archives');
/* Remove archive*/
function makes_remove_wp_archives(){
// if we are on category or tag or date or author archive
if(is_category()|| is_tag()||is_author()){
global $wp_query;
$wp_query->set_404();
}
}
I am new to wordpress. Here is a task for me.
I need to active a plugin that is created already.
Now, when I try to active it, it gives me following error.
The plugin generated 239 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.
So, first thing I did was google. One of the reasong I found was the white-space left behind code somewhere.
So, I followed it and removed blanks from my code. but did not help me out.
Now, I am putting my code herewith this post. Can anyone please help me out. its going really irritating.

I dont know why? no ones gonna answer here. however I found one, it was silly mistake.
register_activation_hook(FILE, 'luckydraw_install');
was called twice, and above call was of no use for me. So I have removed above call, and error has gone.
I have visual composer which is packed with total theme. When I put the following grid short code in my page in the editor it works correctly.
[vc_basic_grid post_type="post_type" max_items="10" item="masonryGrid_SlideFromLeft" grid_id="vc_gid:1458178666639-80ebf3775500c87d35de078c3422fe96-10" taxonomies="555"]
However, when I call the exact same code using do_action it gives the following javascript error. I checked the html output and it is the same using do_action like putting the short code in editor.
Error: Syntax error, unrecognized expression: {'status':'Nothing found'}

Any help is greatly appreciated.
Well, you can't output contents directly in your templates by using core shortcodes of VC like that.
1. Problem:
For security, besides nonce, VC uses page_id and shortcode_id to check AJAX request/respond data.
The shortcode_id is automatically generated by VC, you can not harcode it.
For example, this is the shortcode you see on admin editor screen:
[vc_basic_grid post_type="post_type" max_items="10" item="masonryGrid_SlideFromLeft" grid_id="vc_gid:1458178666639-80ebf3775500c87d35de078c3422fe96-10" taxonomies="555"]
Let say the page ID is 4269, this is the generated HTML code on front-end:
<!-- vc_grid start -->
<div class="vc_grid-container-wrapper vc_clearfix">
<div class="vc_grid-container vc_clearfix wpb_content_element vc_masonry_grid" data-initial-loading-animation="zoomIn" data-vc-grid-settings="{"page_id":4269,"style":"all-masonry","action":"vc_get_vc_grid_data","shortcode_id":"1458178666639-80ebf3775500c87d35de078c3422fe96-10","tag":"vc_masonry_grid"}" data-vc-request="http://example.com/wp-admin/admin-ajax.php" data-vc-post-id="4269" data-vc-public-nonce="0641473b09">
</div>
</div>
<!-- vc_grid end -->
Now, if page_id and shortcode_id don't match each other, {'status':'Nothing found - $shorcode_id'} will be throw out and no contents will be displayed.
You can find out more inside vc_grid.min.js file.
2. Solution:
Generate a fake page with VC, then copy generated html code to your template file.
Create a template with VC directly.
Use Shorcode Mapper to create your own shorcode.
First you build a new page and add a grid post on it,
then we get
_vc_post_settings
post meta , and try to build a new one
then update post meta data
now we can by pass VC Ajax security check
in the following code "1513628284966-37b8c3ca-d8ec-1" is VC generated guid
you should change it to yours .
$meta = get_post_meta(1365,'_vc_post_settings');
$settings = array();
#$settings['vc_grid_id'] = $meta[0]['vc_grid_id'];
$key = random_int(1513628284966,9513628284966);
$settings['vc_grid_id']['shortcodes'][''.$key.'-37b8c3ca-d8ec-1'] = $meta[0]['vc_grid_id']['shortcodes']['1513628284966-37b8c3ca-d8ec-1'];
$settings['vc_grid_id']['shortcodes'][''.$key.'-37b8c3ca-d8ec-1']['atts']['custom_query'] = "tag=shop";
$settings['vc_grid_id']['shortcodes'][''.$key.'-37b8c3ca-d8ec-1']['atts']['grid_id'] = ''.$key.'-37b8c3ca-d8ec-1';
$n = add_post_meta(1365,'_vc_post_settings',$settings);
return do_shortcode("[vc_basic_grid post_type=\"custom\" show_filter=\"yes\" filter_style=\"dropdown\" item=\"5959\" grid_id=\"vc_gid:".$key."-37b8c3ca-d8ec-1\" filter_source=\"post_tag\" custom_query='tag=".$tag."']");
I've solved.
I had the same problems, with the Visual Composer Editor offered by WpBakery
https://wpbakery.com/
and after understanding the connection between the IDs of the block, and the ID of the Post, I put more attention to the settings of the Block.
There is infact one field called "Element ID", and here we have to put our ID of the Post we are editing.
In my case the Block was a block containing some Posts.
After saving, and viewing the page without the Editor, I was finally able to see the block, and not the message
{"status":"Nothing found"}
I found a solution to this problem.
I modified the woocommerce category template and linked to the woocommerce_archive_description hook to add additional descriptions from some pages, for this I got their id, and then display the content.
echo do_shortcode($post->post_content);
The gallery(media grid) didn't work because there was a mismatch between the page id and the shortcode id. Therefore, the logical solution was to redefine the global variable $post to the $post of the page from which I get the content.
global $post;
$post = get_post( $id );
And it turns out that the post id matches.
After that, don't forget to return the normal $post value;
wp_reset_postdata();
By the way - use this option to load custom styles for wpbakery elements.
echo '<style type="text/css" data-type="vc_shortcodes-custom-css">' . get_post_meta( $id, '_wpb_shortcodes_custom_css', true ) . '</style>';
The whole code
function extra_product_category_desc(){
if( is_product_category() ){
$id = get_term_meta (get_queried_object()->term_id, 'pageId', true);
if($id !== ''){
global $post;
$post = get_post( $id );
echo do_shortcode($post->post_content);
echo '<style type="text/css" data-type="vc_shortcodes-custom-css">' . get_post_meta( $id, '_wpb_shortcodes_custom_css', true ) . '</style>';
wp_reset_postdata();
}
}
}
add_action( 'woocommerce_archive_description', 'extra_product_category_desc', 11 );
You may also try with do_shortcode('');
Like
do_shortcode('[vc_basic_grid post_type="post_type" max_items="10" item="masonryGrid_SlideFromLeft" grid_id="vc_gid:1458178666639-80ebf3775500c87d35de078c3422fe96-10" taxonomies="555"]');
Best Regards,
I do not know if I can ask word press templated questions here. I was trying to add a line to functions.php in order to display images in RSS feeds. However, I missed to add a "/ "at the end of my comment line and my website crashed.
I am getting this error:
Fatal error: Call to undefined function load_theme_textdomain() in /home/content/31/6570531/html/wp-includes/functions.php on line 33
the 33 line of functions.php has this line of code:
load_theme_textdomain( 'btp_theme', get_template_directory().'/languages' );
is there anyone who knows what should I do? I reupload template files but still getting the same error.
this is the part of error I think
/* Initialize translation mechanism */
load_theme_textdomain( 'btp_theme', get_template_directory().'/languages' );
$locale = get_locale();
$locale_file = TEMPLATEPATH . "/languages/$locale.php";
if ( is_readable($locale_file) )
require_once($locale_file);
/* EnableWP Auto Feed Links */
add_theme_support('automatic-feed-links');
/* Enable post thumbnails support */
add_theme_support( 'post-thumbnails' );
/* Enable custom backgrounds support */
add_custom_background();
if ( ! isset( $content_width ) ) $content_width = 593;
I solved my problem and want to share it with you.
You should download a fresh copy of WordPress. Than delete
wp-config.php
and
wp-content directory
from your wordpress copy on your harddrive. These are vital steps in order you to not loose your settings and content.
Than upload the Wordpress files via FTP to your server.
