I have already added an link in my widget
eg:
<a target="_blank" href="google.com" class="a-button">Learn More</a>
I need an shortcode like this
[button link="google.com" value="Learn More"]
If i paste this shortcode in widget, page and post, link must appear
Style must be same as above tag
Current Code:
function button_shortcode($atts, $content = null) {
extract( shortcode_atts( array( 'url' => '#' ), $atts ) );
return '' . do_shortcode($content) . '';
}
add_shortcode('button', 'button_shortcode');
How can i do this ?
Basic shortcode will look like this:
function a_button_shortcode( $atts, $content = null ) {
extract($atts);
return '<a target="_blank" href="' . esc_attr($link) . '" class="a-button">' . esc_attr($value) . '</a>';
}
add_shortcode( 'button', 'a_button_shortcode' );
You can read more on shortcode api on: http://codex.wordpress.org/Shortcode_API
In order to make your widget with shortcodes should use do_shortcode( $content ) function inside update method of your widget.
Like this:
function update( $old_instance, $new_instance) {
$new_instance['content'] = do_shortcode($new_instance['content']);
return $new_instance;
}
Or use a plugin that will make it for default widgets like this https://wordpress.org/plugins/shortcodes-in-sidebar-widgets/
add_shortcode("init" ,"add_custom_shortcode");
function add_custom_shortcode()
{
add_shortcode('button', 'buttonShortcode');
}
function buttonShortcode($atts, $text='') {
extract( shortcode_atts( array( 'url' => '#' ), $atts ) );
return '' . do_shortcode($text) . '';
}
thank you all, i tried out this one
function button_shortcode($atts, $content = null) {
extract( shortcode_atts( array(
'url' => '#'
), $atts ) );
return '' . do_shortcode($content) . '';
}
add_shortcode('button', 'button_shortcode');\
For shortcode support in widget paste below line in functions.php
add_filter('widget_text', 'do_shortcode');
created shortcode:
[button url="google.com"]Download[/button]

I added the following code to my functions.php file in WordPress 6.1.1 to display excerpts.
function new_excerpt_length($length) {
return 100;
}
add_filter('excerpt_length', 'new_excerpt_length');
function new_excerpt_more($more) {
return '...';
}
add_filter('excerpt_more', 'new_excerpt_more');
...but I also have a use case to show the full excerpt without a read more link.
On page template 1 I add the below code to display the excerpt:
<?php echo the_excerpt(); ?>
...and it displays the excerpt as per the functions.php file but how do I create a 2nd excerpt without the read more link and apply it to page template 2?
Is there a parameter I can use within the_excerpt(parameter); or can I use something like wp_trim_excerpt https://developer.wordpress.org/reference/functions/wp_trim_excerpt/ maybe?
I came across the below code that is supposed to do what I want
function wpex_get_excerpt( $args = array() ) {
// Default arguments.
$defaults = array(
'post' => '',
'length' => 40,
'readmore' => false,
'readmore_text' => esc_html__( 'read more', 'text-domain' ),
'readmore_after' => '',
'custom_excerpts' => true,
'disable_more' => false,
);
// Apply filters to allow child themes mods.
$args = apply_filters( 'wpex_excerpt_defaults', $defaults );
// Parse arguments, takes the function arguments and combines them with the defaults.
$args = wp_parse_args( $args, $defaults );
// Apply filters to allow child themes mods.
$args = apply_filters( 'wpex_excerpt_args', $args );
// Extract arguments to make it easier to use below.
extract( $args );
// Get the current post.
$post = get_post( $post );
// Get the current post id.
$post_id = $post->ID;
// Check for custom excerpts.
if ( $custom_excerpts && has_excerpt( $post_id ) ) {
$output = $post->post_excerpt;
}
// No custom excerpt...so lets generate one.
else {
// Create the readmore link.
$readmore_link = '' . $readmore_text . $readmore_after . '';
// Check for more tag and return content if it exists.
if ( ! $disable_more && strpos( $post->post_content, '<!--more-->' ) ) {
$output = apply_filters( 'the_content', get_the_content( $readmore_text . $readmore_after ) );
}
// No more tag defined so generate excerpt using wp_trim_words.
else {
// Generate an excerpt from the post content.
$output = wp_trim_words( strip_shortcodes( $post->post_content ), $length );
// Add the readmore text to the excerpt if enabled.
if ( $readmore ) {
$output .= apply_filters( 'wpex_readmore_link', $readmore_link );
}
}
}
// Apply filters and return the excerpt.
return apply_filters( 'wpex_excerpt', $output );
}
Output using:
<?php echo wpex_get_excerpt ( $defaults = array(
'length' => 40,
'readmore' => true,
'readmore_text' => esc_html__( 'read more', 'wpex-boutique' ),
'custom_excerpts' => true,
) ); ?>
...but doesn't seem to workas intended. Outputs the excerpt with no link but the args don't see to work when changed. Would be perfect for my use otherwise. Maybe someone sees how to fix this code?
Thanks
In Woocommerce 3.0 the single variation add to cart button is wrapped in a container div:
<div class="woocommerce-variation-add-to-cart variations_button">
// do_actions for before and after add_to_cart_quantity
</div>
I'd like to filter the html to remove the container div without overriding the variation-add-to-cart-button.php template file and without jquery/javascript.
Any help would be great!
Please try the following code. I haven't tested it but it supposed to work. Please try this on your dev environment first.
add_action( 'woocommerce_before_template_part', function( $template_name ) {
if ( 'single-product/add-to-cart/variation-add-to-cart-button.php' === $template_name ) {
ob_start();
}
} );
add_action( 'woocommerce_after_template_part', function( $template_name ) {
if ( 'single-product/add-to-cart/variation-add-to-cart-button.php' === $template_name ) {
$content = ob_get_clean();
$content = str_replace( '<div class="woocommerce-variation-add-to-cart variations_button">', '', $content );
$content = str_replace( '</div>', '', $content );
echo $content;
}
} );
I am learning how to make wordpress theme. I am doing pretty well. Now I want to make shortcodes. But is is showing Parse error: syntax error, unexpected '}' in E:\xampp\htdocs\wordpress\wp-content\themes\freedom\shortcodes.php on line 17 . I still don't know what is the problem. Here is the code .
<?php
function slider_function( $atts ) {
$atts = extract( shortcode_atts(
array(
'tittle'=>'',
'description'=>'',
'button'=>'',
'button_url'=>''
),$atts ) );
return '
<div class="slider">
<h1>"' . $atts['tittle'] . '"</h1>
<h2>"' . $atts['tittle'] . '"</h2>
</div>'
}
add_shortcode( 'slider','slider_function' );
?>
Take a look at this code how shortcode works and look at your code what returning.
function bartag_func( $atts ) {
$a = shortcode_atts( array(
'foo' => 'something',
'bar' => 'something else',
), $atts );
return "foo = {$a['foo']}";
}
add_shortcode( 'bartag', 'bartag_func' );
You forgot a semicolon /div>';.
function slider_function( $atts ) {
$atts = extract( shortcode_atts(
array(
'tittle'=>'',
'description'=>'',
'button'=>'',
'button_url'=>''
),$atts ) );
return '
<div class="slider">
<h1>"' . $atts['tittle'] . '"</h1>
<h2>"' . $atts['tittle'] . '"</h2>
</div>';
}
add_shortcode( 'slider','slider_function' );
[amazon_s3 bucket=my_bucket_name object=my_file_name.ext]
Hi all i need to know how to fetch the parameter value in the above shortcode. For Example: Object is the attributes then how can i fetch the object value my_file_name.ext. I am using the woocommerce s3 plugin. I am not sure i customized the woocommerce to fetch the file name show in my account page here is the code.
function filename_wc_downloads( $link, $download )
{
$order = new WC_Order( $download['order_id'] );
$download_file_urls = $order->get_downloadable_file_urls(
$download['product_id'],
null,
$download['download_id']
);
foreach( $download_file_urls as $key => $value )
{
if( $value == $download['download_url'] )
{
$url_parts = explode( '/', parse_url( $key, PHP_URL_PATH ) );
$file_name = end( $url_parts );
$link = '<a href="'
. esc_url( $download['download_url'] )
. '">'
. $download['download_name']
. '</a> <small>( '
. $file_name
. ' )</small>';
}
}
return $link;
}
In a Woocommerce all products are uploaded into the media library of upload folder. The above code is to fetch the filename show in my account page if they using direct file path. If i pasted the above shortcode in the product url, that above code doesn't help to fetch the filename. so i need to know from the shortcode how can i get the object value based on this to show the file name.
amazon_s3 is your shortcode containing $atts bucket and object
when you use wordpress function add_shortcode('amazon_s3', 'your_function_name');
it automatically converts your attributes defined in [amazan_s3 .... to $atts
e.g.
function your_funnction_name($atts) {
extract(shortcode_atts(array(
'bucket' => '',
'object' => ''
), $atts));
return $object;
}
I am using Wordpress 3.5, I have a custom post (sp_product) with a metabox and some input field. One of those input (sp_title).
I want to Search by the custom post title name by typing in my input (sp_title) field and when i press add button (that also in my custom meta box), It will find that post by that Title name and bring some post meta data into this Meta box and show into other field.
Here in this picture (Example)
Search
Click Button
Get some value by AJAX from a custom post.
Please give me a example code (just simple)
I will search a simple custom post Title,
Click a button
Get the Title of that post (that i search or match) with any other post meta value, By AJAX (jQuery-AJAX).
Please Help me.
I was able to find the lead because one of my plugins uses something similar to Re-attach images.
So, the relevant Javascript function is findPosts.open('action','find_posts').
It doesn't seem well documented, and I could only found two articles about it:
Find Posts Dialog Box
Using Built-in Post Finder in Plugins
Tried to implement both code samples, the modal window opens but dumps a -1 error. And that's because the Ajax call is not passing the check_ajax_referer in the function wp_ajax_find_posts.
So, the following works and it's based on the second article. But it has a security breach that has to be tackled, which is wp_nonce_field --> check_ajax_referer. It is indicated in the code comments.
To open the Post Selector, double click the text field.
The jQuery Select needs to be worked out.
