Hello and thanks for the guidance!
Trying to load a custom .php file for only my home page (template is page-home.php) by using this code:
add_action('admin_init','load_home_meta');
function load_home_meta() {
global $pagenow, $post;
if ($pagenow=='edit.php' && '104' == $post->ID) {
include 'metaboxes/home-meta.php';
}
}
The page's unique ID is 104. I need this to work only on the home page since the nonce checks in the php file are breaking the ability to save other pages that don't use these custom meta fields.
Thanks!
Try Two:
Tried this:
add_action('admin_init','load_home_meta');
function load_home_meta() {
// Get the Post ID
if( isset( $_GET['post'] ) ) $post_id = $_GET['post'];
elseif( isset( $_POST['post_ID'] ) ) $post_id = $_POST['post_ID'];
if( !isset( $post_id ) ) return;
// Get the Page Template
$template_file = get_post_meta( $post_id, '_wp_page_template', true );
if($template_file == 'page-main-home.php'){
include '/metaboxes/home-main-home.php';
}
}
And seems to be partially working since I'm getting this error on the edit page in the admin section:
Warning: include(/metaboxes/home-main-home.php) [function.include]: failed to open stream: No such file or directory
Warning: include() [function.include]: Failed opening '/metaboxes/home-main-home.php' for inclusion (include_path='.:/usr/local/php-5.3.15/share/pear')
Why would the include work with the simple: include 'metaboxes/home-main-home.php'; ?
I'm also tried the above code with a starting slash and without, both generating the missing/unable to find the file error.
Try Three:
Fixed my template typo error and am no longer not getting to the file with this:
add_action('admin_init','load_home_meta');
function load_home_meta() {
// Get the Post ID
if( isset( $_GET['post'] ) ) $post_id = $_GET['post'];
elseif( isset( $_POST['post_ID'] ) ) $post_id = $_POST['post_ID'];
if( !isset( $post_id ) ) return;
// Get the Page Template
$template_file = get_post_meta( $post_id, '_wp_page_template', true );
if($template_file == 'page-main-home.php'){
include (TEMPLATEPATH . '/metaboxes/home-meta.php');
}
}
But now in each meta-box I'm getting these errors:
Warning: Invalid argument supplied for foreach() in /nfs/c07/h04/mnt/111667/domains/staging.[site_name].org/html/wp-content/themes/[theme_name]/metaboxes/home-meta.php on line 184
But when I comment that out and just do a simple:
include 'metaboxes/home-meta.php';
The backend page renders fine... I'm lost as to what I'm doing incorrectly.
Try Four:
So, all the above still don't work.
Again, I'm trying to:
- Hide the editor on a specific page in the admin backend
- Include custom-fields using metaboxes for only the home (front) page.
- Only serve the home-meta.php file to the front page and no other pages/posts.
functions.php:
/**
* Hide Editor
* @author Bill Erickson
* @link http://www.billerickson.net/code/hide-editor-on-specific-page-template/
*/
add_action( 'admin_init', 'hide_editor' );
function hide_editor() {
// Get the Post ID
if( isset( $_GET['post'] ) ) $post_id = $_GET['post'];
elseif( isset( $_POST['post_ID'] ) ) $post_id = $_POST['post_ID'];
if( !isset( $post_id ) ) return;
// Get the Page Template
$template_file = get_post_meta( $post_id, '_wp_page_template', true );
if($template_file == 'front-page.php'){
remove_post_type_support('page', 'editor');
// add custom .js to footer for uploading images
function custom_admin_js() {
$url = get_option('siteurl');
$url = get_bloginfo('template_directory') . '/library/js/libs/meta-content.js';
echo '"<script type="text/javascript" src="'. $url . '"></script>"';
}
add_action('admin_footer', 'custom_admin_js');
// include 'metaboxes/home-meta.php';
}
}
// Loading Home Page Meta Box Code from External .php file
add_action( 'add_meta_boxes_page','load_home_meta' );
function load_home_meta() {
global $post;
if ( $post->ID == get_option( 'page_on_front' ) ) {
include( get_template_directory_uri() . '/metaboxes/home-main-home.php' );
}
}
I changed my previous home template file to the WordPress recognizable front-page.php since I'm trying to target the home (front) page.
home-meta.php (located in metaboxes in my theme folder)

When I save all that, I get the following errors in the admin backend:

Also, I'm now no longer hiding the content box with the template name change to front-page.php. Tried using the global object of $post to get page_on_front too, but that doesn't work, either.

page-home.php. Is this template for your site front page, or for your blog posts index?
