 * I’m trying to create some input options for users where they can enter things
   like a product price and product description.
 * I’ve tried various plugins, the latest being Just Custom Fields.
 * The problem is that although I can create the fields and they show in the post
   edit page, if I enter a value it disappears when updating the post and doesn’t
   show on the published post.
 * I feel I must be missing something very basic, but I’ve wasted a whole morning
   on this and getting nowhere, so any help or advice would be great – Thanks

 * This is because it is not getting saved into database,
    i personally use ACF (
   [http://www.advancedcustomfields.com/](http://www.advancedcustomfields.com/))
   they are like custom fields but more powerful and more flexible with good tutorial
   documentation/wiki to help you setup

 * Thanks Robin.
 * Yeah, I tried ACF first. Followed all the info I could find, created a new field
   group but wp threw an error for the plugin when trying to publish new posts. 
   Fixed that by registering the new fields in the functions.php. Also created a
   custom post type and added the php ACF suggested. But the common problem I seem
   to have is any value you add to a custom field just disappears when saving or
   publishing a post, and never shows on the post, unless I’ve set a default value
   for it.
 * Must be something basic I’m just not getting.

 * as such with ACF u should not to go and do manual work on functions.php (always
   had worked perfectly for me)
 * Someone has suggested this fix try it out
 * 1. Open file – plugins\advanced-custom-fields\core\actions\input_save.php
    2.
   Go to line number “78” 3. Comment out the line like so //’id’ => null, 4. Save!

 * I did a project sometime back where i added extra fields if the above doesnt 
   work you can take a cue from this code
 * _[ Moderator note: Please use backticks or the code button for code. It make 
   the code much more readable. ]_
 *     ```
       add_action( 'show_user_profile', 'extra_user_profile_fields' );
       add_action( 'edit_user_profile', 'extra_user_profile_fields' );
   
       function extra_user_profile_fields( $user ) { ?>
       <h3><?php _e("Extra profile information", "blank"); ?></h3>
   
       <table class="form-table">
       <tr>
       <th><label for="gender"><?php _e("Gender"); ?></label></th>
       <td>
       <input type="text" name="gender" id="gender" value="<?php echo esc_attr( get_the_author_meta( 'gender', $user->ID ) ); ?>" class="regular-text" />
   
       <span class="description"><?php _e("Enter your Gender."); ?></span>
       </td>
       </tr><tr>
       <th><label for="designation"><?php _e("Designation"); ?></label></th>
       <td>
       <input type="text" name="designation" id="designation" value="<?php echo esc_attr( get_the_author_meta( 'designation', $user->ID ) ); ?>" class="regular-text" />
       <span class="description"><?php _e("Please enter your designation."); ?></span>
       </td>
       </tr></table>
       <?php }
   
       add_action( 'personal_options_update', 'save_extra_user_profile_fields' );
       add_action( 'edit_user_profile_update', 'save_extra_user_profile_fields' );
   
       function save_extra_user_profile_fields( $user_id ) {
   
       if ( !current_user_can( 'edit_user', $user_id ) ) { return false; }
   
       update_user_meta( $user_id, 'gender', $_POST['gender'] );
       update_user_meta( $user_id, 'designation', $_POST['designation'] );
       }

 * Hey Robin
 * Had another go, re-installed ACF but same error,
    ‘Fatal error: Call to a member
   function update_value() on a non-object in /homepages/44/d424921357/htdocs/wp-
   content/plugins/advanced-custom-fields/acf.php on line 721’
 *  and it doesn’t seem to have the file you indicated earlier?
 * “Open file – plugins\advanced-custom-fields\core\actions\input_save.php”
 * Maybe that’s the problem? Just installed it through the wp dash.

 * …….. good grief! Way out of my depth here.
 * Thought it would be easy to add a “price” field to my posts, but maybe not.
 * Probably going to have to stick with my original option of woocommerce or marketpress.
 * But thanks for trying to help 🙂

 * It works fine for me all the time 🙁 not sure where the problem is coming for
   u
 * if u want to add only two fields its not worth installing woocommerce or marketplace
   
   use a simple shopping cart plguin — [http://getshopped.org/](http://getshopped.org/)

 * Bit of a breakthrough (I think).
 * 1. Created a field group with 1 field (price) as text input & saved
    2. Selected
   create php option in settings & added code to functions.php 3. Added ‘<h1><?php
   the_field(‘price’); ?></h1>’ to my post template
 * Ended up with 2 price fields! But at least saving the post didn’t crash. Deleted
   the original field I created to remove the second price entry & it seems to be
   working………..
