Just as an aside, I would recommend any WordPress Developer check out Advanced Custom Fields – I’ve found it saves hours of development time and in some cases can allow you to set up quite useful forms without having to code at all. This trick doesn’t have to be limited to the post type of course – there are many bits of data which could be captured in a similar way onto a form element and used to control the Advanced Custom Fields Conditional Logic of the form. With this in place I can use the same form for both Photos and Challenges, and the relevant parts of the form appear correctly. The final piece of the trick was to set a css class on the radio button to hide it on the form so that it doesn’t interfere with the general flow of the form layout (of course making it hidden also stops it being editable as well) The problem with allowing it to be editable is that if it is changed to ‘Photo’ when a Challenge is being edited, that part of the form disappears and so the control can’t be set back! In the Use column, select the checkbox to turn on the custom field. Name your custom field in the Label column. Double-click any item on the list to open and edit it. With these filters in place the value of the radio button is set and can’t be edited. Go to the Lists menu and select Item List. Unfortunately, as it stands, the conditional logic on the form can only make show / no show decisions based on the elements on the form – you can’t use something like the Post Type to turn on individual parts of the form. This would allow me to cover all the functionality I wanted with a single form which improves the work flow. In order to edit the various metadata which is added to a photo when it’s published on the site, I use an Advanced Custom Fields group to tailor the edit screen and because there are additional fields in a Challenge I wanted to use the Advanced Custom Fields conditional logic to hide a section of the form when the Post Type being edited is a Photo but show it when a Challenge is being edited. The two post types are called, unsurprisingly Photos and Challenges and a Challenge is a subclass of a Photo because it has all the same attributes as a Photo but has a few additional fields.
One to deal with the Photos I publish and another to cover a photo competition which sets Challenges for viewers to try to guess locations or events from some of the pictures. I run a few WordPress blogs as well as Develop with WordPress One of them is a site called Found Film which is a social history site and publishes lost pictures taken by amateur photographers over the last 80 odd years.Īs part of the site architecture I have created two Custom Post Types. for a custom Story Points field, set the value to. In the configuration scheme section, select Edit Default Value. Alternatively, you can click a fields screens or contexts link and then click Contexts > Create, edit or delete contexts. Using Advanced Custom Fields and Background Find the custom field you want to configure, click > Contexts and default value. This post is going to explain a quite useful little trick which allows you to extend the Conditional Logic of an Advanced Custom Fields field group to allow the post type to show or hide section of a form.
