JS templates for Customizer Panels and Sections

Description

Follow up to #28907 and #29572. This is necessary for truly dynamic containers, which don't require any ajax and can be added using the new JS API.

This is required for Menu Customizer, which is currently working around the issue by supplying its own template for a generic section. I'd like to get this done early in 4.2.

Working on a patch that's very similar to #29572, but for sections and panels. It will be possible to override in subclasses, of course, like the existing render/render content methods.

If anyone's wondering why we would ever need dynamically-rendered panels, think things like in-page theme switching, where available options change inline based on the previewed theme.

#10 @westonruter
9 years ago

What about adding to the QUnit tests to check that the new methods work as expected?

Nevermind that we currently don't have any PHPUnit tests at all for WP_Customize_Manager or WP_Customize_Control ;-P

Also, in the case where a panel/section/control's check_capabilities() returns false resulting in the json() method returning null, how will this affect _wpCustomizeSettings in customize.php which is passed into the JS boot logic? There will be panels/sections/controls in that are null.

From looking at customize-controls.js, it seems it would try to pass null into the constructor, and it would even throw a Null is not an object error when attempting api.panelConstructor[ data.type ]. See https://github.com/xwp/wordpress-develop/blob/2b4099c6bd5faa4b99436ab404279699ffc442f9/src/wp-admin/js/customize-controls.js#L2023-L2055

Should the logic instead be moved to customize.php, for instance:

	// Prepare Customize Control objects to pass to JavaScript.
	foreach ( $wp_customize->controls() as $id => $control ) {
		if ( $control->check_capabilities() ) { // this conditional added
			$settings['controls'][ $id ] = $control->json();
		}
	}

Really, however, that whole blob of logic in customize.php should be moved to a new method on WP_Customize_Manager, like WP_Customize_Manager::get_configuration()

#12 @celloexpressions

I don't think we should hold this up for unit tests since most of the Customizer code still needs unit tests. But if you're able to write some for this, it wouldn't hurt (that's not within my scope of abilities).

I think it's important to keep objects from potentially being sent to JS if the caps aren't available within the control/panel/section objects, but it would probably work if that was handled by the manager. We should probably move all of that logic out of customize.php in another ticket, so should we just move the checks there for now?

#13 @DrewAPicture
9 years ago

Not already having unit tests does not a compelling argument make for skipping them for new functionality.

#14 @kuus
9 years ago

I think it would be great to expose the Container class to the js API. Because otherwise extending the Section or Panel classes with a custom one is a bit problematic. It would be an easy change here: https://github.com/xwp/wordpress-develop/blob/customize-2.0/src/wp-admin/js/customize-controls.js#L227

Anyway thanks for your great work on the Customizer API.

#15 @celloexpressions
9 years ago

If we're going to wait for someone to write unit tests, then this is in a holding pattern indefinitely. I think it's okay without them, but I don't do them so I don't really know. If we need unit tests, we're probably going to have to punt, which has significant implications on the timeline of things like menus in the Customizer happening in core.

#16 @westonruter
9 years ago

In 30737.4.diff:

  • Remove check_capabilities() calls from json() methods since redundant with prepare_controls()
  • Wrap setting exporting with cap checks.
  • Add cap checks to panels, sections, and controls before adding to JS exports.

PR: https://github.com/xwp/wordpress-develop/pull/59/files

@celloexpressions: I'll try to add the unit tests over the next 48 hours.

New menus in Menu Customizer will require users to close the Customizer to go back to the menus panel until we can get this ticket fixed as of #31336. #31336 will also require the actual JS templates for panels and sections to be rewritten, which I can take care of as soon as the first-pass is committed there, along with a general refresh. In the meantime, we need unit tests still, so if anyone can work on those that would be great.

We also need to do this as a first step for #30741, which should also be in 4.3 if at all possible, but that won't happen if we don't get moving here soon.

#36 @westonruter
9 years ago

@celloexpressions I noticed something that may be unexpected when testing with Menu Customizer. Namely, I had to make sure I added:

$this->manager->register_section_type( 'WP_Customize_Menu_Section' );

Or else the custom sections would never render. Nevertheless, Menu Customizer just needed the default section to render right? So it seems that if a custom section didn't have register_section_type called, it should fallback to render the default section.

So I'm suggesting an additional patch something like this:

  • src/wp-admin/js/customize-controls.js

     
    170170   container.params = {};
    171171   $.extend( container, options || {} );
    172172   container.templateSelector = 'customize-' + container.containerType + '-' + container.params.type;
     173   if ( ! document.getElementById( 'tmpl-' + container.templateSelector ) ) {
     174    container.templateSelector = 'customize-' + container.containerType + '-default';
     175   }
    173176   container.container = $( container.params.content );
    174177   if ( 0 === container.container.length ) {
    175178    container.container = $( container.getContainer() );
     
    12111214   */
    12121215  renderContent: function () {
    12131216   var template,
     1217    templateSelector,
    12141218    panel = this;
    12151219
     1220   if ( document.getElementById( 'tmpl-' + panel.templateSelector + '-content' ) ) {
     1221    templateSelector = panel.templateSelector + '-content';
     1222   } else {
     1223    templateSelector = 'customize-' + panel.containerType + '-default-content';
     1224   }
     1225
    12161226   // Add the content to the container.
    1217    if ( 0 !== $( '#tmpl-' + panel.templateSelector + '-content' ).length ) {
    1218     template = wp.template( panel.templateSelector + '-content' );
     1227   if ( 0 !== $( '#tmpl-' + templateSelector ).length ) {
     1228    template = wp.template( templateSelector );
    12191229    if ( template && panel.container ) {
    12201230     panel.container.find( '.accordion-sub-container' ).html( template( panel.params ) );
    12211231    }

Only two things remain before closing this out:

1) Address the question I've raised regarding falling back to the templates for default types.

2) Provide a set of default params when constructing new Section and Panel objects (and even Controls). As discussed in Slack, if you fail to supply a param.type, then it will not even fall back to the default template, but will try to use a undefined template, which is even worse. So something like this would be good, to go along with my suggestion above.

In 30737.addendum.diff I add QUnit tests for the template fallbacks, and then I also add default params for panels and sections when they are constructed, along with documenting the parameters that are accepted by their constructors.

#47 @ocean90
9 years ago

30737.addendum.2.diff moves defaultParams out of api.Container.initialize to a defaults property and adds a defaults property to api.Section. I think this looks a bit cleaner since api.Container shouldn't care about child objects (api.Section).

#48 follow-up: @celloexpressions

Looks good to me. Only thing - can we set the action to something better by default? Since that is required for the UI to look right now. Would it be feasible to pass "Customizing > " to JS and then get the parent panel title if it exists?

I'm not a fan of adding a default string here. The UI needs to handle views without an action, for example the Themes "panel" shows an action, which is wrong.
