Issues displaying custom meta box value on post edit page - 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' );

Meta Box data not saving when updating the post

I am banging my head against the wall as to the culprit. Is there anything in my code that is wrong? I have also tried dropping out of php and using regular html code, but that does not work.

Custom meta box for page template not saving data

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');

Cannot get metadata from database for custom post types

Already tried using save_post and updated_post actions.
Here's the code:
function la_add_custom_metabox() {
add_meta_box(
'la_meta',
__( 'Dados de Cadastro' ),
'la_meta_callback',
'cota',
'normal',
'core'
);
}
add_action( 'add_meta_boxes', 'la_add_custom_metabox' );
My custom field:
function la_meta_callback(){
wp_nonce_field( basename( __FILE__ ), 'la_cotas_nonce' );
$la_stored_meta = get_post_meta( $post->ID ); ?>
<div>
<div class="meta-row">
<div class="meta-th">
<label for="credito" class="dwwp-row-title"><?php _e( 'Crédito', 'la-cotas' ); ?></label>
</div>
<div class="meta-td">
<input type="text" class="dwwp-row-content" name="credito" id="credito" value="<?php if ( ! empty ( $la_stored_meta['credito'] ) ) { echo esc_attr( $la_stored_meta['credito'][0] ); } ?>"/>
</div>
</div>
</div>
Function that saves in database
function la_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[ 'la_cotas_nonce' ] ) && wp_verify_nonce( $_POST[ 'la_cotas_nonce' ], basename( __FILE__ ) ) ) ? 'true' : 'false';
// Exits script depending on save status
if ( $is_autosave || $is_revision || !$is_valid_nonce ) {
return;
}
if ( isset( $_POST[ 'credito' ] ) ) {
update_post_meta( $post_id, 'credito', sanitize_text_field( $_POST[ 'credito' ] ) );
}
}
add_action( 'save_post', 'la_meta_save' );
I tried many tutorials in internet, and i couldn't find what i'm doing wrong.
expected: The data to be inserted in the database and being displayed in the custom edit page field.
Edit 1: I discovered that the data is being saved, but its not being displayed on the edit fields.
Solved: For those who are interested: I wasn't passing $post on the save_meta callback
//This solved the problem
function la_meta_callback($post){ ... }

Wordpress Custom Post Type Meta Box not saving to database

I've created a Custom Post Type 'media-page-items' that I'm attempting to add meta boxes to. Currently the meta boxes are showing but not saving to the database. I've tried a few different approaches on it and none of them seem to save to database.
Debug is turned on but no errors are being thrown currently that I can see.
Any help is much appreciated!
//add article link to media page item
add_action( 'admin_menu', 'gruman_article_link_create' );
add_action( 'save_post', 'gruman_article_link_save', 10, 2 );

add_meta_box( 'gruman-article-link', 'Article Link', 'gruman_article_link', 'media-page-items', 'advanced', 'high' );
}
function gruman_article_link( $post ) {
// retrieve the _gruman_article_title current value
$current_article_link = get_post_meta( $post->ID, '_gruman_article_link', true );
?>
<p>
<label>Article Link</label>
<br />
<input name="gruman-article-link" id="article-link" style="width: 97%;"><?php $current_article_link; ?>/>
<input type="hidden" name="gruman_article_link_nonce" value="<?php echo wp_create_nonce( plugin_basename( __FILE__ ) ); ?>" />
</p>
<?php }
function gruman_article_link_save( $post_id ) {
// verify taxonomies meta box nonce
if ( !isset( $_POST['gruman_article_link_nonce'] ) || !wp_verify_nonce( $_POST['gruman_article_link_nonce'], basename( __FILE__ ) ) ){
return $post_id;
}
// return if autosave
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ){
return $post_id;
}
// Check the user's permissions.
if ( !current_user_can( 'edit_post', $post_id ) ){
return $post_id;
}
// store article title value
if ( isset( $_REQUEST['gruman-article-link'] ) ) {
update_post_meta( $post_id, '_gruman_article_link', sanitize_text_field( $_POST['gruman-article-link'] ) );
}
}
In wp_create_nonce you are using plugin_basename( __FILE__ ).
And when you verifying nonce you use basename( __FILE__ ) as action name.
Those values are not the same. First one will return something like my-plugin/my-plugin.php and the second will be my-plugin.php
That is why I believe wp_verify_nonce returns False and your data is not saved.

WordPress - how to add custom meta box to a specific admin page?

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:

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
