I used the above code to create a metabox in Wordpress. But , for that
code it doesn't showing up
couldn't find the solution. kindly suggest any ideas for that problem
.
It all depends on where you want the metabox to appear.
If you want it to appear on posts then you need to use
if ( ! function_exists( 'add_post_metabox' ) ){
function add_post_metabox(){
add_meta_box('post-meta', esc_html__('My Metabox', 'mytheme'), 'My_Metabox_function', 'post', 'side', 'low');
}
}
add_action('admin_init', 'add_post_metabox');
And then create metabox with
if ( ! function_exists( 'My_Metabox_function' ) ){
function My_Metabox_function( $post ){
//metabox layout and variables here
}
}
if ( ! function_exists( 'My_Metabox_save_function' ) ){
function My_Metabox_save_function($post_id){
global $post;
if ( defined('DOING_AUTOSAVE') && DOING_AUTOSAVE ){
return $post_id;
} else{
//do save here
}
}
}
add_action( 'save_post', 'My_Metabox_save_function' );
If you want it on page then you can create it like above but with page instead of post
if ( ! function_exists( 'add_page_metabox' ) ){
function add_page_metabox(){
add_meta_box('page-meta', esc_html__('My Metabox on Page', 'mytheme'), 'My_Metabox_page_function', 'page', 'normal', 'high');
}
}
add_action('add_meta_boxes', 'add_page_metabox');
You can hook to admin_init of add_meta_boxes hooks. See here for more explanation.
You can put it in your functions.php file or you can set it in separate .php file and call it in functions.php with something like:
require_once( get_template_directory(). '/include/metaboxes.php' );
This will include metaboxes.php that are located in the /include directory of your theme.

I have a woocommerce store.
Its an affiliate store.
I want that when clicked on the featured image on the shop page it goes to an external website
I have added below code to my function.php its working fine just need to know what code and where is to be added to open it in a new tab
**<?php // Do not include this if already open!
/**
* Code goes in theme functions.php.
*/
add_action( 'template_redirect', 'redirect_external_products' );
function redirect_external_products() {
global $post;
if ( is_singular( 'product' ) && ! empty( $post ) && ( $product = wc_get_product( $post ) ) && $product->is_type( 'external' ) ) {
wp_redirect( $product->get_product_url() );
exit;
}
}**
There is no way to redirect in a new tab, I will suggest adding "target='_blank'" to the tag where you display the featured image with probably the same condition as in the function above. The hacky way maybe
add_action( 'template_redirect', 'redirect_external_products' );
function redirect_external_products() {
global $post;
if ( is_singular( 'product' ) && ! empty( $post ) && ( $product = wc_get_product( $post ) ) && $product->is_type( 'external' ) ) {
echo "<script> window.open(" . $product->get_product_url() . ", '_blank') </script>";
}
}
But I strongly suggest you not to go this way!!
I want to show the css and javascript only when the shortcode is used in that page. If the short code not present in the wordpress page then the js and css of contact form should not be shown. For that what i have done is i have pasted the following code in my active themes function.php file.
add_filter( 'wpcf7_load_js', '__return_false' );
add_filter( 'wpcf7_load_css', '__return_false' );
The above code totally removes the js and css of contact form 7 plugin. What i need is if contact form 7 shortcode is pasted then both should be shown.
Here is the answer for your question. If there is not shortcode the css and js of contact form will be removed and if there is shortcode css and js will be added.
function rjs_lwp_contactform_css_js() {
global $post;
if( is_a( $post, 'WP_Post' ) && has_shortcode( $post->post_content, 'contact-form-7') ) {
wp_enqueue_script('contact-form-7');
wp_enqueue_style('contact-form-7');
}else{
wp_dequeue_script( 'contact-form-7' );
wp_dequeue_style( 'contact-form-7' );
}
}
add_action( 'wp_enqueue_scripts', 'rjs_lwp_contactform_css_js');
I needed the other version that corresponds widgets and shortcodes in theme file.
add_filter( 'wpcf7_load_css', '__return_false' );
add_filter( 'wpcf7_load_js', '__return_false' );
remove_action( 'wp_enqueue_scripts','wpcf7_recaptcha_enqueue_scripts', 20 );
add_filter('pre_do_shortcode_tag', 'enqueue_wpcf7_css_js_as_needed', 10, 2 );
function enqueue_wpcf7_css_js_as_needed ( $output, $shortcode ) {
if ( 'contact-form-7' == $shortcode ) {
wpcf7_recaptcha_enqueue_scripts();
wpcf7_enqueue_scripts();
wpcf7_enqueue_styles();
}
return $output;
}
You use below code.You can add your pages Id in this code.
function dvk_dequeue_scripts() {
$load_scripts = false;
if( is_singular() ) {
$post = get_post();
if( has_shortcode($post->post_content, 'contact-form-7') ) {
$load_scripts = true;
}
}
if( ! $load_scripts ) {
wp_dequeue_script( 'contact-form-7' );
wp_dequeue_style( 'contact-form-7' );
}
}
add_action( 'wp_enqueue_scripts', 'dvk_dequeue_scripts', 99 );

We created a plugin with a new template and we want to hook the main theme function and return the main plugin function.
We tried it with:
add_filter( "page_template", "test" );
function test( $template ) {
if( 'plugin_name.php' == basename( $template ) )
$template = WP_PLUGIN_DIR . '/plugin_folder/plugin_name.php';
return $template;
}
and changed page template in theme functions with main function of plugin which runs template inside plugin:
add_filter( "page_template", "main_plugin_function" );
Is page_template the right filter to change theme template?
Thanks for help!
I think you should use template_include filter, this filter hook is executed immediately before WordPress includes the predetermined template file. This can be used to override WordPress's default template behavior.
For example
add_filter( 'template_include', 'portfolio_page_template', 99 );
function portfolio_page_template( $template ) {
if ( is_page( 'portfolio' ) ) {
$new_template = locate_template( array( 'portfolio-page-template.php' ) );
if ( '' != $new_template ) {
return $new_template;
}
}
return $template;
}

I am trying to add a custom stylesheet to the TinyMCE editor in a WordPress plugin I am developing. The WP codex tells me to use the mce_css filter, but it does not seam to work.
As soon, as I use the filter, all the theme's custom stylesheets disappears from the editor, but my custom stylesheet is still not there.
See the following two screenshots, the first without the filter, the second with the filter activated:
Here is my code:
class test_plugin {
function __construct($args = array()){
if ( is_admin() ){
add_action('admin_head', array( $this, 'admin_head') );
add_action( 'admin_enqueue_scripts', array($this , 'admin_enqueue_scripts' ) );
}
}
function admin_head() {
if ( !current_user_can( 'edit_posts' ) && !current_user_can( 'edit_pages' ) ) {
return;
}
if ( 'true' == get_user_option( 'rich_editing' ) ) {
add_filter( 'mce_css', 'plugin_mce_css' );
}
}
function admin_enqueue_scripts(){
// wp_enqueue_style('fa_icon_shortcode', plugins_url( 'css/mce-button.css' , __FILE__ ) );
}
function plugin_mce_css( $mce_css ) {
if ( ! empty( $mce_css ) )
$mce_css .= ',';
$mce_css .= plugins_url( 'editor.css', __FILE__ );
return $mce_css;
}
}
new test_plugin();
Any idea what goes wrong here?
It actually was a pretty simple solution. Since I am using OOP, I had to add the filter with
add_filter( 'mce_css', array( $this , 'plugin_mce_css' ) );
instead of
add_filter( 'mce_css', 'plugin_mce_css' );
Works like charm!
I am trying to add a custom meta box to a wordpress page which stores a value in a custom field. It is not working. The meta box is displayed but when you press update the value entered ito the text box is lost and nothing is written to the wp_postmeta table (no _c3m_sponsor_ur meta_key is created)
I have adapted this from an example online. I also tried adding a die statement to see if the save post is even called but nothing dies. I also dont understand why the add_post_meta isn't being created for the page
add_action( 'add_meta_boxes', 'c3m_sponsor_meta' );
function c3m_sponsor_meta() {
add_meta_box( 'c3m_meta', 'Sponsor URL Metabox', 'c3m_sponsor_url_meta', 'page', 'side', 'high' );
}
function c3m_sponsor_url_meta( $post ) {
$c3m_sponsor_url = get_post_meta( $post->ID, '_c3m_sponsor_url', true);
if (!isset($c3m_sponsor_url))
add_post_meta($post->ID, '_c3m_sponsor_url', '', false);
echo 'Please enter the sponsors website link below';
?>
<input type="text" name="c3m_sponsor_url" value="<?php echo esc_attr( $c3m_sponsor_url ); ?>" />
<?php
}
add_action( 'save_post', 'c3m_save_project_meta' );
function c3m_save_project_meta( $post_ID ) {
die('here');
global $post;
if( $post->post_type == "page" ) {
if (isset( $_POST ) ) {
update_post_meta( $post_ID, '_c3m_sponsor_url', strip_tags( $_POST['c3m_sponsor_url'] ) );
}
}
}
Any help in fixing this is muh appreciated
Thanks a lot
This may be help you:--
add_action( 'save_post', 'c3m_save_project_meta' );
function c3m_save_project_meta( $post_ID ) {
if ( isset( $_POST['post_type'] ) && 'page' == $_POST['post_type'] )
{
if (isset( $_POST ) ) {
update_post_meta( $post_ID, '_c3m_sponsor_url', strip_tags( $_POST['c3m_sponsor_url'] ) );
}
}
}
Edited:-
You can simply use Advanced Custom Fields plugin instead of using code. This plugin much helpful for custom meta fields.
