how can i understand a short code is exist in my wordpress post?
[tbps id="1"] is the short code . Where id may vary . ie 2,3 ...
i paste this code in wordpdpress post namely mypost ,it is working .So how can i get the shortcode which exists in wordpress page (in mypost). i don't know how to use this code
<?php
if ( shortcode_exists( 'yourCondition ' ) ) {
//Here i don't know how to use 'yourCondition' .Because condition
//is varying .It may be [tbps id="1"] ,[tbps id="2"] ,[tbps id="3"] etc
}
?>
<?php
if ( shortcode_exists( 'yourCondition ' ) ) {
// The [gallery] short code exists.
}
?>
you can try
In wordpress 3.6 and above you can do this... Say your shortcode like this... [fts youtube username=GoProCamera vid_count=5]
// Detect if the shortcode exists in a post page or widget
global $post;
if( is_a( $post, 'WP_Post' ) && has_shortcode( $post->post_content, 'fts youtube') ) {
wp_enqueue_style( 'fts_youtube_css', plugins_url( 'youtube/css/styles.css', dirname(__FILE__) ) );
}
This works even if you use multiple shortcodes on a page, post or widget, and of course will not duplicate your styles or js because you are enqueueing them. Tested and confirmed. https://codex.wordpress.org/Function_Reference/has_shortcode

I'm using WordPress with Elementor, I want a certain page to be accessible only if it comes from a certain url. I saw from other answers in similar questions that I can use this:
add_action( 'template_redirect', 'wpse15677455_redirect' );
function wpse15677455_redirect() {
$value = ('https://mywebsite.com/quotaton/') ;
if (!is_page(555) & wp_get_referer() !== $value ) {
wp_safe_redirect( get_home_url() );
}
};
I tried using this in the function.php of the theme but it returns the error "Unable to communicate with server to check for fatal errors". I tried with all plugins deactivated except elementor but same result.
I tried without the add_action call but, despite not giving errors, it also does nothing. I can't seem to find the right place/way to use this function.
Trying out the code, I believe the problem is that you're missing a single ampersand(&) for the And operator. Also, if is_page is used to check for the "certain page", maybe the not(!) operator isn't necessary...
if (is_page(555) && wp_get_referer() !== $value ) {
function custom_redirects() {
if ( is_front_page() ) {
wp_redirect( home_url( '/dashboard/' ) );
die;
}
if ( is_page('contact') ) {
wp_redirect( home_url( '/new-contact/' ) );
die;
}
}
add_action( 'template_redirect', 'custom_redirects' );
is_page('contact') => 'contact' is page slug.
is_page(150) => '150' is page ID.
If the link that has to be redirected comes from a page, you could use a redirection plugin like this one: https://it.wordpress.org/plugins/page-links-to/
Once activated you just edit the page you want to be redirected inserting the correct link in the page links to field.
The built in wordpress function is_search() determines whether the query is for a search (source). In this form, the function does not distinguish between post types.
What im trying is to load a script only on the search results page for posts but not the search results for products. For example:
function child_theme_search_custom_js_script() {
if ( is_search() ) { // But only for default post type?
wp_enqueue_script( 'child-theme-cart-js', get_stylesheet_directory_uri() . '/js/child-search-custom-js.js', array('abc-core'), '1.0.0', true );
}
}
add_action( 'wp_enqueue_scripts', 'child_theme_search_custom_js_script' );
Any way to check if it is the results page for the default post type?
So i played around with different wordpress conditions and found a solution to target only the search results page for the default post type.
// If it is "Post" Post Type Search Results Page only
if ( ! is_post_type_archive() && is_search() ) {
I am running a wholesale shop on Woocommerce. Login is required to see the prices. This is set up and working properly. Now I wish to add a logon form on every product page to only show to visitors (not logged on users).
I am using the WooCommerce Catalog Visibility plugin. This plugin offers the functionality I described above, but my theme is somehow messing it up. The plugin author says to talk to the theme developer and the theme developer says to talk to the plugin author. So now I am trying to find a workaround.
First issue: The plugin comes with a shortcode [woocommerce_logon_form] that will display a logon form. I don't want to manually add this to every existing product since I have thousands of products on my site. I am looking for a way to get it in through the code for the product page layout.
I found this code (to be added to the functions.php) to work well:
// adds notice at single product page above add to cart
add_action( 'woocommerce_single_product_summary', 'return_policy', 20 );
function return_policy() {
echo '<p id="rtrn">30-day return policy offered. See Terms and Conditions for details.</p>';
}
However, it will only show text. The short code won't work when added instead of the sample text.
Second issue: The short code shows the form even when the customer is already logged in.
I am currently using this nice code that shows or hides content depending on whether the user is logged in or not:
add_shortcode( 'access', 'access_check_shortcode' );
function access_check_shortcode( $attr, $content = null ) {
extract( shortcode_atts( array( 'capability' => 'read' ), $attr ) );
if ( current_user_can( $capability ) && !is_null( $content ) && !is_feed() )
return $content;
return '';
}
add_shortcode( 'visitor', 'visitor_check_shortcode' );
function visitor_check_shortcode( $atts, $content = null ) {
if ( ( !is_user_logged_in() && !is_null( $content ) ) || is_feed() )
return $content;
return '';
}
That shortcode works perfectly for text, but not with other shortcodes.
So the combination of these short codes: [visitor][woocommerce_logon_form][/visitor] will not show the logon form to visitors. Instead it will only show them this as text [woocommerce_logon_form].
Please help! I am sure this is probably easily fixed by someone with coding skills.
I appreciate your effort to answer to this question. Keep in mind that my understanding of code is very limited and it would be great if you can also point out in which file to add or modify code.
To make your shortcode working in php code or in php/html code you need to use a native WordPress function do_shortcode() … You can use it with your shortcode for example in your 1st function this way:
add_action( 'woocommerce_single_product_summary', 'return_policy', 20 );
function return_policy() {
echo do_shortcode('[woocommerce_logon_form]');
}
And this will work…
To see all the different hooks you can use instead of woocommerce_single_product_summary, please see this 2 templates code to chose in case a more convenient hook:
WooCommerce single-product.php template
WooCommerce content-single-product.php template
You can also add it the same way in one of your existing short codes, this way:
add_shortcode( 'visitor', 'visitor_check_shortcode' );
function visitor_check_shortcode( $atts, $content = null ) {
if ( ( !is_user_logged_in() && !is_null( $content ) ) || is_feed() )
return do_shortcode('[woocommerce_logon_form]');
return '';
}
And this will work too.
See as reference this answer: Change markup in WooCommerce shortcode output
So as you can see your problem is solved on both issues
I have a client site running on WordPress. It uses WooThemes Canvas as its base theme (with a customized child theme), and utilizes the Time.ly All-in-one-Event Calendar. It can be viewed here.
The design I came up with required me to move the page/post titles outside the main content area. I followed the instructions on this WooThemes customization document, and made modifications based on the comments so that it would also work for posts and the Time.ly event postings. The entries in my functions.php file looked like this:
add_filter( 'the_title', 'woo_custom_hide_single_post_title', 10 );
function woo_custom_hide_single_post_title ( $title ) {
if ( is_singular( array( 'post', 'ai1ec_event' ) ) && in_the_loop() ) { $title = ''; }
return $title;
} // End woo_custom_hide_single_post_title()
add_filter( 'the_title', 'woo_custom_hide_single_page_title', 10 );
function woo_custom_hide_single_page_title ( $title ) {
if ( is_page() && in_the_loop() ) { $title = ''; }
return $title;
} // End woo_custom_hide_single_page_title()
// Add Titles above Content Area on all Posts & Pages
add_action( 'woo_content_before_singular-post', 'woo_custom_add_title', 10 );
add_action( 'woo_content_before_singular-ai1ec_event', 'woo_custom_add_title', 10 );
add_action( 'woo_content_before_singular-page', 'woo_custom_add_title', 10 );
function woo_custom_add_title () {
if ( ! is_page_template(array('template-biz.php', 'template-brewpub.php')) ) {
global $post;
$title = '<h1 class="page-title">' . get_the_title( $post->ID ) . '</h1>' . "";
echo '<div id="title_container"><header class="col-full">';
echo $title;
woo_post_meta();
echo '</header></div>';
}
} // End woo_custom_add_post_title()
This produced some undesirable results, which can be seen on the DEV site I setup for this post (dev.thebrewworks.com):
Since the Time.ly event calendar also uses the_title to display it's events, in the three instances I used the calendar inside a page loop (the homepage and the two restaurant location pages), the event titles don't show up. This was confirmed by creating a Test Page (dev.thebrewworks.com/test-page), where you can see two instances of the calendar inside the loop, and one outside (in the sidebar). The two instances in the Loop have no titles, while the sidebar does.
Supressing the_title in the Loop didn't suppress the Post Meta, which still shows up in the main content area, but I want it under the title in the new DIV, so reposting woo_post_meta outside the Loop leaves me with two instances of the Post Meta.
In order to get the site live I had to make some concessions in my functions.php file:
// Hide Titles on All Posts & Pages
add_filter( 'the_title', 'woo_custom_hide_single_post_title', 10 );
function woo_custom_hide_single_post_title ( $title ) {
if ( is_singular( array( 'post', 'ai1ec_event' ) ) && in_the_loop() ) { $title = ''; }
return $title;
} // End woo_custom_hide_single_post_title()
add_filter( 'the_title', 'woo_custom_hide_single_page_title', 10 );
function woo_custom_hide_single_page_title ( $title ) {
if ( is_page() && in_the_loop() && is_page_template( array('page.php', 'template-contact.php' ) ) ) { $title = ''; }
return $title;
} // End woo_custom_hide_single_page_title()
// Add Titles above Content Area on all Posts & Pages
add_action( 'woo_content_before_singular-post', 'woo_custom_add_title', 10 );
add_action( 'woo_content_before_singular-ai1ec_event', 'woo_custom_add_title', 10 );
add_action( 'woo_content_before_singular-page', 'woo_custom_add_title', 10 );
function woo_custom_add_title () {
if ( ! is_page_template(array('template-biz.php', 'template-brewpub.php')) ) {
global $post;
$title = '<h1 class="page-title">' . get_the_title( $post->ID ) . '</h1>' . "";
echo '<div id="title_container"><header class="col-full">';
echo $title;
woo_post_meta();
echo '</header></div>';
}
} // End woo_custom_add_post_title()
// Disable Post Meta
function woo_post_meta() {}
?>
Note the changes:
I disabled the post_meta completely. Not exactly what I was looking for, but better than having it show up twice.
I modified the function that disables the page title so that it only works on pages that use certain templates (the three instances I mentioned above use the Business Template in Canvas that already suppresses the page title). This would require me to go in and add each new page template that I want to suppress the title on, though...and on top of that, it's not working. Take a look at the live site. The page title is showing up twice on static pages. Once inside the white content area and once outside in the yellow header.
I'm no PHP-developer...I'm more of an Design/HTML/CSS person. I know enough to be dangerous...how to modify existing code, etc., but not necessarily how to write my own from scratch. I have no idea if the way I came up with things is even the best/most elegant way to go about it. Now that you have all the facts, here are my questions:
In an ideal world, the Post Meta would ONLY show up on the blog entries (not on the calendar entries...no need for them there, really), and OUTSIDE the main content area underneath the page title that I moved. How can I achieve this? I'm guessing it's going to be some sort of conditional statement that removes the woo_post_meta from all instances inside the loop, and adds it to the woo_custom_add_title ONLY if it's a standard post, but how to get there I have no idea.
How can I suppress the_title that shows up at the top of the content area on ALL static pages, regardless of template, but have it not affect instances of the_title that appear elsewhere in the loop (like the calendar syndication). In my head there has to be a way to indicate that you ONLY want to disable the_title if it's in a certain div/id, etc., but again...only enough to be dangerous, unless I see it done elsewhere, I can't come up with the solution on my own.
Thanks in advance for your input.
I am trying to redirect my WordPress homepage to the newest article automatically.
At the moment I use a redirect suggested by Spencer Cameron
function redirect_homepage() {
if( ! is_home() && ! is_front_page() )
return;
wp_redirect( 'http://homepage.com/article1', 301 );
exit;
}
add_action( 'template_redirect', 'redirect_homepage' );
Now if I post article 2 I want the homepage to automatically connect to article 2 without me adjusting the functions.php.
I want no user to see the www.example.com but only the article, so there is always a redirect to the newest article when visiting the page.
However:
I want to have the possibility to still access www.example.com/article1 (by manually typing the url) even if there is already www.example.com/article2.
How could I achieve that goal?
The answer is in Get the ID of the latest post: do a simple query to get one post (ordered by latest by default), then grab its permalink and redirect.
Don't put this type of code in functions.php, create your own mini-plugins to do it. If you want to disable this, it's just a matter of disabling a plugin, and not of editing a file.
<?php
/* Plugin Name: Redirect Homepage */
add_action( 'template_redirect', 'redirect_homepage' );
function redirect_homepage()
{
if( ! is_home() && ! is_front_page() )
return;
// Adjust to the desired post type
$latest = get_posts( "post_type=post&numberposts=1" );
$permalink = get_permalink( $latest[0]->ID );
wp_redirect( $permalink, 301 );
exit;
}
A solution from a friend:
Replace index.php in the template folder with the following:
<?php global $query_string; query_posts($query_string.'&posts_per_page=1'); ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php header('Location: '.get_permalink()); ?>
<?php endwhile; ?>
Thanks for helping me out
