        if (!wp_verify_nonce($_POST['avz_custom_meta_box_fields_nonce'], basename(__FILE__))) 
            return $post_id;
        // check autosave

            $new = $_POST[$field['id']];
            if ($new && $new != $old) {
                update_post_meta($post_id, $field['id'], $new);
            } elseif ('' == $new && $old) {
                delete_post_meta($post_id, $field['id'], $old);
            }
        } // enf foreach

        // save taxonomies
        $post = get_post($post_id);
        $category = $_POST['category'];
        wp_set_object_terms( $post_id, $category, 'category' );
    }
    add_action('save_post', 'save_multiBox_custom_meta');

And in single.php

if( $image_upload_id = get_post_meta($post->ID, $field['custom_image'], true)){
    $img = $image_upload_id ['custom_image'][0];
    echo wp_get_attachment_image($img, 'full'); 
}

But can’t find attached image. In admin uploaded image show but in post page not showing. Guys help me. i know i am doing mistakes and bad coding.

Is the Theme supporting Custom Fields?

I just only add this code and in admin Custom Post Type showing the image upload form when i upload the image it shows in custom meta box area. But i can’t retrieve in post page.

Guys i need help.

Hi,

in single php you call:

Why $field[‘custom_image’] ??? What’s $field? single.php is for the front end… so you shouldn’t have the $field array set…

I guess you should just do:

Hi Guys i found some solution but i shows all images upload in post but i want to show only image from my meta box that i upload.

working code example but shows all image upload .

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); $args = array( ‘post_type’ => ‘attachment’, ‘numberposts’ => -1, ‘post_status’ => null, ‘post_parent’ => $post->ID ); $attachments = get_posts( $args ); if ( $attachments ) { foreach ( $attachments as $attachment ) { echo ‘
• ’; echo wp_get_attachment_image( $attachment->ID, ‘full’ ); echo ‘

  ’; echo apply_filters( ‘the_title’, $attachment->post_title ); echo ‘

’; } } endwhile; endif; ?>

if( $image_upload_id = get_post_meta($post->ID, $field['custom_image'], true)){
    $image_upload_id = get_post_meta($post->ID, $field['custom_image'], true);
    $img = $image_upload_id ['custom_image'][0];
    echo wp_get_attachment_image($img, 'full'); 
}

So friend i want to show image which i upload through custom meta box.

Is ‘custom_image’ the key of the meta? You’re code isn’t clear… why are you saving attachments into the custom fields?

// Default metabox for custom post types.
function avz_custom_meta_box() {

   // $post_types = get_post_types( array( 'public' => true ) );
   $post_types = get_post_types();
    foreach ( $post_types as $post_type ) {
        if ( $post_type == 'page' || $post_type =='post' )
            continue;
        add_meta_box(
        'custom_image', 
        'Header Image Upload Box', 
        'show_avz_custom_meta_box', 
        $post_type, 
        'normal', 
        'high' );
    }

}
add_action('add_meta_boxes', 'avz_custom_meta_box');

^ Ok, so you’re creating a metabox with id custom_image.

Now, the ‘custom_image’ id will never retrun anything in the front, is the id of your metabox…

For sure you have some fields in this metabox and you save the values in specific custom fields through a key…

To call in the front end the custom field where you store the image you should know the key you used to create and update the custom field:

update_post_meta($post_id, $field[‘id’], $new);

The key you use here $field[‘id’] for sure returns a string… well that’s the string you should use when calling get_post_meta in the front

What’s the $field[‘id’] for the image? You should know that…

Dude i done work like charm but i think its bad 2 time looops can you check, ALthough what i want this code does.

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); 

if( $image_upload_id = get_post_meta($post->ID, $field['custom_image'], true)){
    $image_upload_id = get_post_meta($post->ID, $field['custom_image'], true);
    $img = $image_upload_id ['custom_image'][0];
    echo wp_get_attachment_image($img, 'full'); 
}

 endwhile; endif; ?>

But in this page again i m using loop:

<?php
if( have_posts() ) {
  while( have_posts() ) {
    the_post();
    ?>

<?php the_content(); ?>

so what you think is fine, Two loops in page.

Because i can’t retrieve image without loop that’s why i use two loops.
