Post Custom Field Wizard

Test 1: Post Custom Field Wizard in three HIdden fields, then revealed in LHTML using hidden field values:

Issue: Not sure why the LHTML field shows in editor, but not in frontend.

Issue: 3W1_enrolled when it has a value of zero does not show up.

Test 2: Post Custom Field Wizard in three HIdden fields, then tried update_post_meta to increment enrolled field.

Issue: No luck -update_post_meta maybe won't work in JS, there is some other problem causing it to show value as NaN.

Test 2a JS Field - simple getField not working

Test 2 JS Field with getField("var", true), and update_post_meta - not working

Test 3: Using {-:{post:'3W2_max'} 1} dynamic shortcode in Number field to update the meta.

Issue: Decrement and non-decrement work but the decrement only effects what is shown on the page, doesn't update the custom field value.

decrement using post shortcode in Number field

just post shortcode in Number field

Test 4: Post Custom Field in Text Field - works

Post Custom Field in default Text Field with before attr set

Using update_post_meta to change value of 3W1_enrolled meta data.To see how it works, comment out with double slash the update_meta_data in the PHP code. Also observe the Custom Fields in the Edit Panel

Issues:

It does not appear to update the Custom Field in the Edit panel.
It updates all of the values everywhere on the page, so there is no way to see the old value.
Not sure if custom fields are for the SESSION or shared across multiple SESSIONS

PHP with update_post_meta

Test 6: Trying updateSelf as shown on dynamic.ooo help - not sure what this function does or how to use it.

JS Sync updateSelf

Test 7: Trying implode to see how it works with an array - useful function
