im creating a custom metabox as such:
<?php
/**
* Plugin Name: Relaterade sidor
* Description: lägg till relaterade sidor
* Version: 1.0
* Author: test
* Author URI: test
*
*/
function relaterade_sidor_get_meta( $value ) {
global $post;
$field = get_post_meta( $post->ID, $value, true );
if ( ! empty( $field ) ) {
return is_array( $field ) ? stripslashes_deep( $field ) : stripslashes( wp_kses_decode_entities( $field ) );
} else {
return false;
}
}
function relaterade_sidor_add_meta_box() {
add_meta_box(
'relaterade_sidor-relaterade-sidor',
__( 'relaterade sidor', 'relaterade_sidor' ),
'relaterade_sidor_relaterade_sidor_html',
'post',
'normal',
'default'
);
add_meta_box(
'relaterade_sidor-relaterade-sidor',
__( 'relaterade sidor', 'relaterade_sidor' ),
'relaterade_sidor_relaterade_sidor_html',
'page',
'normal',
'default'
);
}
add_action( 'add_meta_boxes', 'relaterade_sidor_add_meta_box' );
function relaterade_sidor_relaterade_sidor_html( $post) {
wp_nonce_field( '_relaterade_sidor_relaterade_sidor_nonce', 'relaterade_sidor_relaterade_sidor_nonce' ); ?>
<p>relaterade sidor</p>
<p>
<label for="relaterade_sidor_relaterade_sidor_url"><?php _e( 'Url', 'relaterade_sidor' ); ?></label><br>
<input type="text" name="relaterade_sidor_relaterade_sidor_url" id="relaterade_sidor_relaterade_sidor_url" value="<?php echo relaterade_sidor_get_meta( 'relaterade_sidor_relaterade_sidor_url' ); ?>">
</p><?php
}
function relaterade_sidor_relaterade_sidor_save( $post_id ) {
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;
if ( ! isset( $_POST['relaterade_sidor_relaterade_sidor_nonce'] ) || ! wp_verify_nonce( $_POST['relaterade_sidor_relaterade_sidor_nonce'], '_relaterade_sidor_relaterade_sidor_nonce' ) ) return;
if ( ! current_user_can( 'edit_post' ) ) return;
if ( isset( $_POST['relaterade_sidor_relaterade_sidor_url'] ) )
update_post_meta( $post_id, 'relaterade_sidor_relaterade_sidor_url', esc_attr( $_POST['relaterade_sidor_relaterade_sidor_url'] ) );
}
add_action( 'save_post', 'relaterade_sidor_relaterade_sidor_save' );
/*
Usage: relaterade_sidor_get_meta( 'relaterade_sidor_relaterade_sidor_url' )
*/
?>
the text remains in the textfield after saving/updating so I guess that means it is saved to the database, but when trying to display the data in a page or post I only get blank.
I tried with both these ones:
<?php if (have_posts()) : while (have_posts()) : the_post();
$intro = get_post_meta(get_the_ID(), 'relaterade_sidor-relaterade-sidor', true);
echo "content: " . $intro;
?>
<?php
global $wp_query;
$postid = $wp_query->post->ID;
echo get_post_meta($postid, 'relaterade_sidor-relaterade-sidor', true);
wp_reset_query();
?>
But I only get blank, cant get it to display the content saved in the custom meta textbox.
Sorry, was trying to connect it to the metabox name when i should connect the key,
$intro = get_post_meta(get_the_ID(), 'relaterade_sidor_relaterade_sidor_url', true);
echo "content: " . $intro;
works just fine inside the loop
I suggest CMB2 library. No more headaches with metaboxes ;)

Been banging my head against the wall trying to figure out the solution to my current issue. Simply put, I've created a 'page-home.php' template page, can get a meta box to call on the page template, but trying to update the page with data in the meta box makes the data disappear.
Code below:
function page_add_meta_boxes( $post ) {
global $post;
if(!empty($post))
// get the page template post meta
$page_template = get_post_meta( $post->ID, '_wp_page_template', true );
// if the current page uses our specific template, then output our custom metabox
{
$pageTemplate = get_post_meta($post->ID, '_wp_page_template', true);
// looks for page-home.php file to add our meta box
if($pageTemplate == 'page-home.php' )
{
add_meta_box(
'page-custom-metabox', // $id
'Special Post Meta', // $title
'page_template_metabox', // $callback
'page', // $page
'normal', // $context
'high'); // $priority
}
}
}
add_action( 'add_meta_boxes_page', 'page_add_meta_boxes' );
function page_template_metabox() {
wp_nonce_field( basename( __FILE__ ), 'page_meta_box_nonce' );
$some_string = get_post_meta( $post->ID, '_some_string', true );
?>
<input type="text" name="some-string" value="<?php echo $some_string; ?>" />
<?php
}
function page_save_custom_post_meta() {
if ( !isset( $_POST['page_meta_box_nonce'] ) || !wp_verify_nonce( $_POST['page_meta_box_nonce'], basename( __FILE__ ) ) ){
return;
}
// return if autosave
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ){
return;
}
// check the user's permissions.
if ( ! current_user_can( 'edit_page', $post_id ) ){
return;
}
// save our string
if ( isset( $_REQUEST['some-string'] ) ) {
update_post_meta( $post_id, '_some_string', sanitize_text_field( $_POST['some-string'] ) );
}
}
add_action( 'publish_page', 'page_save_custom_post_meta' );
add_action( 'draft_page', 'page_save_custom_post_meta' );
add_action( 'future_page', 'page_save_custom_post_meta' );
Any suggestions are appreciated.
Howdy anyone who runs into this in the future. I was able to get it to work with the code below, someone might be able to follow up with a better answer as to why it works. My thinking is that updating my code to 'save_post_page' instead of just 'save_post' makes the difference. (Note I only changed some info due to trying to test it in my theme):
// Add meta box
function frontpage_meta_boxes( $post ){
global $post;
if(!empty($post))
$page_template = get_post_meta( $post->ID, '_wp_page_template', true );
{
$pageTemplate = get_post_meta($post->ID, '_wp_page_template', true);
if($pageTemplate == 'page-home.php' )
{
add_meta_box( 'frontpage_meta_box', __( 'Features' ), 'frontpage_meta_box', 'page', 'advanced', 'high' );
}
}
}
add_action( 'add_meta_boxes_page', 'frontpage_meta_boxes' );
// builds our meta box
function frontpage_meta_box( $post ){
// make sure the form request comes from WordPress
wp_nonce_field( basename( __FILE__ ), 'frontpage_meta_box_nonce' );
// retrieve the _manuf_url current value
$manufacturer_url = get_post_meta( $post->ID, '_manuf_url', true );
?>
<h3><?php _e( 'Manufacturer URL' ); ?></h3>
<p>
<input type="text" name="manufacturer-url" value="<?php echo $manufacturer_url; ?>" />
</p>
<?php
}
// saves our data
function frontpage_save_meta_box_data( $post_id ){
// verify meta box nonce
if ( !isset( $_POST['frontpage_meta_box_nonce'] ) || !wp_verify_nonce( $_POST['frontpage_meta_box_nonce'], basename( __FILE__ ) ) ){
return;
}
// return if autosave
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ){
return;
}
// Check the user's permissions.
if ( ! current_user_can( 'edit_post', $post_id ) ){
return;
}
// manufacturer url string
if ( isset( $_REQUEST['manufacturer-url'] ) ) {
update_post_meta( $post_id, '_manuf_url', sanitize_text_field( $_POST['manufacturer-url'] ) );
}
// store custom fields values
}
add_action( 'save_post_page', 'frontpage_save_meta_box_data' );
Try with below code :
function page_save_custom_post_meta($postid) {
if ( !isset( $_POST['page_meta_box_nonce'] ) || !wp_verify_nonce( $_POST['page_meta_box_nonce'], basename( __FILE__ ) ) ){
return;
}
// return if autosave
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ){
return;
}
// check the user's permissions.
if ( ! current_user_can( 'edit_page', $post_id ) ){
return;
}
// save our string
if ( isset( $_REQUEST['some-string'] ) ) {
update_post_meta( $post_id, '_some_string', sanitize_text_field( $_POST['some-string'] ) );
}
}
add_action('save_post ','page_save_custom_post_meta');
How can I add my custom meta box to a specific page only on the admin page?
Here is my custom meta box code which I got it from here:

function prfx_meta_save( $post_id ) {

$is_valid_nonce = ( isset( $_POST[ 'prfx_nonce' ] ) && wp_verify_nonce( $_POST[ 'prfx_nonce' ], basename( __FILE__ ) ) ) ? 'true' : 'false';
// Exits script depending on save status

return;

Use this js it will resolve your problem. this will show the metabox on perticular template or page..
(function($){
$(document).ready(function() {
var $page_template = $('#pageid')
,$metabox1 = $('#metaboxid');
$page_template.change(function() {
if ($(this).val() == 'templatename') {
$metabox1.show();
} else {
$metabox1.hide();
}
}).change();
});
})(jQuery);
if you are using this in admin then use admin hook and add this code in functions.php
I am trying to add some custom meta boxes to my wordpress post edit page. I have the box added (Video URL) but when I attempt to call the info from the post into the field as the set value nothing ever shows. I believe I am saving it correctly, but I can't get it to show after being saved, please help. Here is the code for adding and saving the meta box info:
<!-- adding the video url meta box prototype data -->
<?php
add_action( 'add_meta_boxes', 'cd_meta_box_add' );
function cd_meta_box_add()
{
add_meta_box( 'post-video', 'Video URL', 'video_url_meta_box', 'post', 'side', 'high' );
}
?>
<!-- rendering the video url meta box on the post edit page -->
<?php
function video_url_meta_box( $post )
{
$value = get_post_meta( $post->ID, 'video_url_text', true );
wp_nonce_field( 'video_url_nonce', 'meta_box_nonce' );
?>
<p>
<label for="video_url_text">Youtube or Vimeo URL</label>
<input type="text" name="video_url_text" id="video_url_text" value="<?php echo $value; ?>" />
</p>
<?php
}
?>
<!-- Saving the video url meta box data -->
<?php
add_action( 'save_post', 'video_url_save' );
function video_url_save( $post_id )
{
//return if we're doing an auto save
if( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;
//return if we can't verify nonce or it isn't there
if( !isset( $_POST['video_url_nonce'] ) || !wp_verify_nonce( $_POST['meta_box_nonce'], 'video_url_nonce' ) ) return;
//return if the current user can't edit the post
if( !current_user_can( 'edit_page' ) ) return;
// save data once all checks are passed
// make sure the url is set
if( isset( $_POST['video_url_text'] ) )
update_post_meta( $post_id, 'video_url_text' );
}
?>
I ended up moving all of the code into a custom plugin and got it working as shown below:
/**
* Adds the meta boxes to the post editing screen
*/
function weshine_meta_boxes() {
add_meta_box( 'video_url_meta', __( 'Video URL', 'video-url-text' ), 'video_url_meta_callback', 'post', 'side', 'high' );
add_meta_box( 'caption_text_meta', __( 'Caption Text', 'thumb-caption-text' ), 'caption_text_meta_callback', 'post', 'side', 'high');
}
add_action( 'add_meta_boxes', 'weshine_meta_boxes' );
/**
* Outputs the content of the meta box
*/
function video_url_meta_callback( $post ) {
wp_nonce_field( basename( __FILE__ ), 'prfx_nonce' );
$video_url_stored_meta = get_post_meta( $post->ID );
?>
<p>
<label for="video-url" class="prfx-row-title"><?php _e( 'Enter Youtube or Vimeo URL', 'video-url-text' )?></label>
<input type="text" name="video-url" id="video-url" value="<?php if ( isset ( $video_url_stored_meta['video-url'] ) ) echo $video_url_stored_meta['video-url'][0]; ?>"$
</p>
<?php
}
/**
* Saves the custom meta input
*/
function video_url_meta_save( $post_id ) {
// Checks save status
$is_autosave = wp_is_post_autosave( $post_id );
$is_revision = wp_is_post_revision( $post_id );
$is_valid_nonce = ( isset( $_POST[ 'prfx_nonce' ] ) && wp_verify_nonce( $_POST[ 'prfx_nonce' ], basename( __FILE__ ) ) ) ? 'true' : 'false';
// Exits script depending on save status
if ( $is_autosave || $is_revision || !$is_valid_nonce ) {
return;
}
// Checks for input and sanitizes/saves if needed
if( isset( $_POST[ 'video-url' ] ) ) {
update_post_meta( $post_id, 'video-url', sanitize_text_field( $_POST[ 'video-url' ] ) );
}
}
add_action( 'save_post', 'video_url_meta_save' );
Found a function which add to my admin panel one meta-box. It's looks nice, but not enough.
I need at least ten custom fields. How to create them?
The questoins looks stupid, because my knowledge of php are minimal, so do not judge strictly ;). I will be grateful for the solution of this problem or an explanation of how it should work.

If your knowledge of PHP is quite low, there are some great plugins that allow you to do this easily.
If you have a lot of fields to add, I usually find it easier to use the following plugin as ordering fields and pulling them out in themes is a lot easier than doing it manually.
http://wordpress.org/plugins/advanced-custom-fields/
So, I added an input field to one of my post types.
What I'm trying to do is put a link (google.com, facebook.com, any link) into this field, and have it output on the front end into a button.
Below is my button. I would like it to go to the link I placed on the input field when I click the button.
<?php echo __('Purchase Now','Vierra'); ?>
Here's the code for the metabox:
<?php
add_action( 'add_meta_boxes', 'cart_meta_box_add' );
function cart_meta_box_add() {
add_meta_box( 'cart-meta-box-id', 'Put cart Here!', 'cart_meta_box_cb', 'Room', 'side', 'high' );
}
function cart_meta_box_cb() {
wp_nonce_field( basename( __FILE__ ), 'cart_meta_box_nonce' );
$value = get_post_meta(get_the_ID(), 'cart_key', true);
$html = '<label>cart: </label><input type="text" name="cart" value="'.$value.'"/>';
echo $html;
}
add_action( 'save_post', 'cart_meta_box_save' );
function cart_meta_box_save( $post_id ){
if( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;
if ( !isset( $_POST['cart_meta_box_nonce'] ) || !wp_verify_nonce( $_POST['cart_meta_box_nonce'], basename( __FILE__ ) ) ) return;
if( !current_user_can( 'edit_post' ) ) return;
if( isset( $_POST['cart'] ) )
update_post_meta( $post_id, 'cart_key', esc_attr( $_POST['cart'], $allowed ) );
}
?>
Thank you for the help!
It's the same function used in the admin: get_post_meta(). Assuming the button is being printed inside the loop *:
<?php
if( $field = get_post_meta( get_the_ID(), 'cart_key', true ) ) {
?>
<a href="<?php echo $field; ?>" id="btn-book-now" class="btn-custom">
<?php echo __('Purchase Now','Vierra'); ?>
</a>
<?php
}
?>
* Otherwise, you'd use $post->ID instead of get_the_ID().
