I have a theme for an eCommerce website and my homepage is built with wpbakery. Products displayed in the homepage are not changing after refresh. All the products are in the same place. I found no option in wpbakery elements to change order by random. How can I add this functionality?
I am sure in wpbakery there is a way you can do this by selecting a random option. But if you are unable to find it check and see if this works in your case.
add_action('pre_get_posts', 'my_pre_get_posts');
function my_pre_get_posts($query) {
if ( $query->is_home() && $query->is_main_query() ) {
$query->set('orderby', 'rand');
}
}
Put the code in your function file. It will set your homepage post orderby rand. Hope it works but I advise you to follow WPbakery setting to do that.
Simple Steps to find your way in WPbakery
make sure your plugin is active
Go to the page set as your homepage and click on edit page
open the post setting in the wpbakery
Select Data setting
Choose the first option which is "Order by"
scroll down and select "Random order" and save your setting.
That should point you to the right way to set random post order in WPbakery.

currently my theme on WordPress is Neve , and my posts all over the blog shows the following meta info :
https://i.stack.imgur.com/ynu71.jpg
where :
1- post title
2- post author
3- post date
4- post category
i want to replace these post meta with similar to this:
https://i.stack.imgur.com/Xywa9.jpg
for this purpose i have created a child theme and then installed snippet plugin to add php code easily and deactivate it once it is not working . unfortunately i could not find the code that can do the required modifications on that post meta :
https://i.stack.imgur.com/uwCrS.jpg
can any one provide a full php code to modify all these changes in one time after pasting into snippet ? or if there is another way i can do it ?
You'll have to create a child theme (already done) where you can override the current blog post template, instead of using a snippet plugin. To do this, copy the blog post template file from your theme and add it to your child theme.
WordPress will now read your child theme template instead of your theme's template, and you can easily modify the DOM from there, and shape the layout/text however way you want. (You can use the theme editor built-in in WordPress to modify the new child theme file. No plugin required.)
This is the proper way to modify a post page without plugins, and you can easily grab thing such as a post date, author, etc. via WordPress' built-in function. Example of how to get the author name of a WordPress post in PHP.
As for, 'latest edition' date, I will lend you a snippet I wrote for a client as WordPress. This will return the date at which a post has been modified as long as it is different from the publishing date (tweaks are common right after publication so it's a tad pointless to show a "last edited date" as the same as the publication date).
function current_post_last_edited_date_formatted() {
if(get_the_modified_date() !== get_the_date()) {
return '<p class="last-edited"> Last edited <span class="data">'.current_post_last_edited_date().'</span></p>';
} else {
return '';
};
}
The function you see called in the condition are WordPress core functions. =)
Yesterday I installed a new theme on Wordpress on my self-hosted website. I am aware of the feature that allows you to preview a theme and have used it to select a new Theme that I want to install.
Problem
I do not want to interrupt normal operations of my website, but this new theme requires a lot of customization before it is ready to go. How do I do this?
My Crappy Solution
Is the only way to go about it to run a virtual server on my desktop? This seems tedious, not to mention all the errors I usually get when switching to the "real" server when doing this.
A better way?
I've been searching on SO as well as the WordPress Forum for an answer as to how to do this, but have come up short. I would have thought this is a common question. Maybe I'm using the wrong search terms [themes, customization, before installing]???
Any help is greatly appreciated! Thanks!
Ok, since your question is a pretty good one and probably not a few people are going through the same process when they decide to update their site, I decided to give a try to the get_stylesheet and get_template filter hooks. It turns out that with a very small plugin, you can easily enforce a specific theme(well in this case any logged-in visitor, but you can change this to use any logic you want) according to a specific rule/s.
Here's the code that you need to put in a file in your plugins directory:
<?php
/*
Plugin Name: Switch Theme
Description: Switches the theme for logged-in visitors, while keeping the current theme for everyone else. !!!NOTE!!! Please back-up your database prior using this plugin - I can't guarantee that it will work with any theme, nor that it won't break your site's set-up - USE AT YOUR OWN RISK(I did a quick test and it seemed to be fine, but haven't done extensive testing).
You don't need to switch to the desired theme before that - you want to keep active the theme that you will display to your visitors - the one that you will see will be used programatically.
Before activating the plugin, change the line that says `private $admin_theme = '';` to `private $admin_theme = 'theme-directory-name';` where "theme-directory-name" is obviously the name of the directory in which the desired theme resides in.
*/
class MyThemeSwitcher {
private $admin_theme = '';
function MyThemeSwitcher() {
add_filter( 'stylesheet', array( &$this, 'get_stylesheet' ) );
add_filter( 'template', array( &$this, 'get_template' ) );
}
function get_stylesheet($stylesheet = '') {
if ( is_user_logged_in() && $this->admin_theme ) {
return $this->admin_theme;
}
return $stylesheet;
}
function get_template( $template ) {
if ( is_user_logged_in() && $this->admin_theme ) {
return $this->admin_theme;
}
return $template;
}
}
$theme_switcher = new MyThemeSwitcher();
So - first of all BACKUP YOUR DATABASE! I tested locally with Twenty Eleven being the default theme and a basic framework theme as my custom theme - the theme options and navigation menus were saved properly.
Then all you need to do is to update the file(change the line that says private $admin_theme = ''; to private $admin_theme = 'theme-slug'; where theme-slug is the name of the directory in which the theme you want to use is).
Also - you won't be able to change the Front page and Posts page options, without this affecting the live site, nor will you be able to change the any shared components that both themes use(Site name, Front Page, Posts page, Posts Per Page, etc options, content and so on).
So if you have no clue whether this solution is for you - well, it depends.
If both themes are not relatively complex, then most-likely you should be able to use this hack. If they are though maybe you should do a second installation of your website as others suggested - I think that a second installation in either a sub-domain or a sub-directory would be the best option for you(simply because moving a multisite database is more complex than moving a normal WP database).
I'd setup local apache server with a wordpress installed to customize and test a new theme. When you finished customizing it then you can upload the theme to your live site and activate it. If there are settings that you need to set in the dashboard then you probably will have to adjust them again. That's one way to test/customize a theme before putting it live.
You could create a network (make WordPress multisite with define('WP_ALLOW_MULTISITE', true);, see : http://codex.wordpress.org/Create_A_Network) and then create one sub-site, then turn it "off" with a Maintenance plugin so it is not accessible to users not logged in as admin, export your posts & data from main blog, import them in sub-blog with WordPress default importer, then apply your new theme to this sub-blog and work on it. When everything satisfies you, apply the theme to the main site and deactivate subsite.
Hi I am reading Building wordpress themes from scratch in order to understand theme development.I got to a point in the book where it explains how to create the custom post type pages.And the author mentions that this function is required in order to display the page:
add_action('init' , 'director_rewrite');
function director_rewrite(){
global $wp_rewrite;
$wp_rewrite->add_permastruct('typename','typename/%year%%postname%/' , true , 1);
add_rewrite_rule('typename/([0-9]{4})/(.+)/?$','index.php?typename=$matches[2]', 'top');
$wp_rewrite->flush_rules();
}
I have deleted the function and the page still display corectly without it.That leads me to belive that I do not understand wha this actualy does.
So is this function required to properly display custom post type pages?If so what does it do?
It adds rewrite rule for the permalinks structure of your page. If you remove it, the page still show correctly, but link towards your page is different!
I have already developed my plugin for WordPress and I can manage it from admin. I have passed the access to the plugin file using add_submenu_page. The problem is that the plugin is extending and I want to use another file that is linked from the main file. For example I have second_page.php?id=3. When I try to access this link, I get a
You do not have sufficient permissions to access this page.
message. I want to "validate" this page also for using with this script and I don't know how. Ideas?
When you add a page with add_submenu_page(), the url should be something like:
wp-admin/admin.php?page=<your_page_handle>
Your page is actually loaded from admin.php (typically). You can add parameters to your links by appending something like &id=3 and then have your main plugin page-loading logic determine which file to include based on the parameter.
For instance
if (isset($_GET['id']) && ((int) $_GET['id']) == 3) {
include 'second_page.php';
} else {
include 'first_page.php';
}
Edit:
I found a trick that may be easier for you, though I haven't thoroughly tested it. Let's say that you have two pages: my_one and my_two. Just call add_submenu_page twice, and set the second page's parent as the first page. This will cause Wordpress to not add a link to the navigation bar, but you can still access your page by navigating to admin.php?page=my_two.
Example:
add_submenu_page(
'my_toplevel_link'
, 'Page Title'
, 'Link Name'
, 'administrator'
, 'my_one' // here's the page handle for page one
, 'my_one_callback'
);
add_submenu_page(
'my_one' // set the parent to your first page and it wont appear
, 'Page Title'
, 'Link Name' // unused
, 'administrator'
, 'my_two'
, 'my_two_callback'
);
Since WP natively supports URLs like wp-admin/admin.php?page=<your_page_handle> you can do sub pages with something like:
wp-admin/admin.php?page=yourpage
wp-admin/admin.php?page=yourpage&sub=2
wp-admin/admin.php?page=yourpage&sub=3
Then in the code that handles wp-admin/admin.php?page=<your_page_handle> you just look at the $_GET and pull up the main page or a sub-page as needed.
I've definitely seen plugins where the admin page has a little row of links across the top linking the various sub-pages.
I want my WordPress blog to have a page called music. On that page I will query the DB for posts with the category music and then change around the look and feel of the posts. So I can't just put a link to /categories/music/ because I want to do custom work on the posts.
Should I put this code in a separate php file and link to it? I think I may lose access to all the nice WordPress API calls if I do that.
I was thinking about using a filter, but I am not sure which one to use. I was thinking something like the following except the_title has not been grabbed yet so I cannot check the title.
function show_music(){
if( is_page() && the_title('','',false) == 'music' ){
echo "got here";
}
}
add_filter('pre_get_posts', 'show_portfolio');
How would you go about this?
You need to put the below code in the file, and then put the file in the Theme folder. Then you can create a page using Wordpress pages and select a page template with the name you put in this comment:
/*
Template Name: Something Goes Here
*/
You need to create custom page within your theme. If you dont have idea how to create custme page or template page in WordPress theme then view my easy tutorial How to create template page in WordPress
