I’ve simplified a problem of saving custom metaboxes on update and still can’t get the box to save the custom-field input to the database.
This is the call from functions.php
to an external file /metaboxes/home-meta-new.php
:
// Loading Home Page Meta Box Code from External .php file
add_action( 'add_meta_boxes_page','load_home_meta' );
function load_home_meta() {
$post_id = $_GET['post'] ? $_GET['post'] : $_POST['post_ID'];
if($post_id == '104'){
include( get_template_directory() . '/metaboxes/home-meta-new.php' );
}
}
That part works as it shows the one meta box from the home-meta-new.php
file.
Unfortunately, once values are input for the custom-fields and the user clicks update, the post refreshes without saving the values. Here is the home-meta-new.php
code:
<?php
/**
* Home Page Custom Meta Content
*
**/
add_meta_box(
'home_meta_box', // $id
'Home Page Content', // $title
'show_home_meta_box', // $callback
'page', // $page
'normal', // $context
'high'); // $priority
// Creating Array for Fields
$prefix = '_home_';
global $home_meta_fields;
$home_meta_fields = array(
array(
'label' => 'Caption Title',
'desc' => 'Upper section H2 caption title.',
'id' => $prefix.'title',
'type' => 'text'
),
array(
'label' => 'Caption Sub Title',
'desc' => 'Upper section H3 caption title.',
'id' => $prefix.'sub_title',
'type' => 'text'
),
array(
'label'=> 'Caption',
'desc' => 'Caption text block.',
'id' => $prefix.'caption',
'type' => 'textarea'
),
array(
'label' => 'Caption Image',
'desc' => 'Upload a pre-cropped 1140px wide x 530px tall web-optimized image.',
'id' => $prefix.'image',
'type' => 'image'
)
);// end home_meta array
//The Callback
function show_home_meta_box() {
global $home_meta_fields, $post;
// Using nonce for verification
echo '<input type="hidden" name="home_meta_box_nonce" value="'.wp_create_nonce('home_upper_nonce').'" />';
//wp_nonce_field( 'home_upper_nonce', 'home_upper_nonce' );
//Begin field table and loop
echo '<table class="form-table">';
foreach ($home_meta_fields as $field) {
// get value of this field if it exists for this page
$meta = get_post_meta($post->ID, $field['id'], true);
// begin a table row with
echo '<tr>
<th><label for="'.$field['id'].'">'.$field['label'].'</label></th>
<td>';
switch($field['type']) {
// case items will go here
// text
case 'text':
echo '<input type="text" name="'.$field['id'].'" id="'.$field['id'].'" value="'.$meta.'" size="30" />
<br /><span class="description">'.$field['desc'].'</span>';
break;
// textarea
case 'textarea':
echo '<textarea name="'.$field['id'].'" id="'.$field['id'].'" cols="60" rows="4">'.$meta.'</textarea>

break;
case 'image':
$image = get_template_directory_uri().'/library/images/img-preview-blank.png';
echo '<span class="custom_default_image" style="display:none">'.$image.'</span>';
if ($meta) { $image = wp_get_attachment_image_src($meta, 'medium'); $image = $image[0]; }
echo '<input name="'.$field['id'].'" type="hidden" class="custom_upload_image" value="'.$meta.'" />
<img src="'.$image.'" class="custom_preview_image" style="max-width:300px" alt="" /><br />
<input class="custom_upload_image_button button" type="button" value="Choose Image" />
<small> <a href="#" class="custom_clear_image_button">Remove Image</a></small>
<br clear="all" /><span class="description">'.$field['desc'].'';
break;
} // end switch
echo '</td></tr>';
} // end foreach
echo '</table>'; // end table
}// end build metabox callback
// Save the Data
function save_home_meta($post_id) {
global $home_meta_fields;
// verify nonce
//option one
//if (!wp_verify_nonce($_POST['home_meta_box_nonce'], basename(__FILE__)))
//return $post_id;
//option two
if (isset($_POST['home_meta_box_nonce'])){
if ( !wp_verify_nonce( $_POST['home_meta_box_nonce'], 'home_upper_nonce' ) )
return;
}else{return;}
// check autosave
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)
return $post_id;
// check permissions
if ('page' == $_POST['post_type']) {
if (!current_user_can('edit_page', $post_id))
return $post_id;
} elseif (!current_user_can('edit_post', $post_id)) {
return $post_id;
}
// loop through fields and save the data
foreach ($home_meta_fields as $field) {
$old = get_post_meta($post_id, $field['id'], true);
$new = $_POST[$field['id']];
//if ($new && $new != $old) {
if ($new && ($new != $old)) {
update_post_meta($post_id, $field['id'], $new);
} elseif ('' == $new && $old) {
delete_post_meta($post_id, $field['id'], $old);
}
} // end foreach
}
add_action('save_post', 'save_home_meta');
// end save_home_meta
?>
Anyone able to identify where it’s choking on the save? Thanks!
When you do that
include
, you are trying to add thesave_post
hook inside theadd_meta_boxes_$post_type
hook. It should be independent.Also, you shouldn’t declare a function inside a function. Maybe you should consider creating a plugin for handling this, see: Where to put my code: plugin or functions.php?.
Or, if you really want it inside your theme’s
functions.php
, do ainclude
for all this meta box code.You’ll find plenty of working examples here, check this search query:
