TinyMCE example: Allow added custom relative paths in TinyMCE

Shows how to extend the HyperLink editor descriptor and use the TinyMCE custom link dialog box to let an editor create links relative to the site.

📘

Note

This example applies to CMS UI 11.21.1 and higher.

This scenario shows how to extend the HyperLink editor descriptor and use the TinyMCE custom link dialog to let an editor create links relative to the site. For example, if the site host is www.alloydemo.com and the relative link is news/my-video, the link will redirect to www.alloydemo.com/news/my-video.

  1. Register an EditorDescriptor for HyperLink UIHint. Set the EditorDescriptorBehavior to PlaceLast. As a result, the original descriptor is executed first, and you can apply custom settings.

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using EPiServer.Shell.ObjectEditing;
    using EPiServer.Shell.ObjectEditing.EditorDescriptors;
    
    namespace AlloyTemplates.Business.EditorDescriptors {
      [EditorDescriptorRegistration(
        TargetType = typeof (string),
        UIHint = "HyperLink",
        EditorDescriptorBehavior = EditorDescriptorBehavior.PlaceLast)]
      internal class CustomLinkEditorDescriptor: EditorDescriptor {
        public override void ModifyMetadata(ExtendedMetadata metadata, IEnumerable<Attribute> attributes) {
          base.ModifyMetadata(metadata, attributes);
    
          if (!metadata.EditorConfiguration.ContainsKey(("providers"))) {
            return;
          }
    
          var providers = (metadata.EditorConfiguration["providers"] as IEnumerable<object>).ToList();
    
          providers.Add(new {
            Name = "Site link",
              Title = "Site link",
              DisplayName = "Site relative link",
              WidgetType = "dijit/form/ValidationTextBox"
          });
    
          metadata.EditorConfiguration["providers"] = providers;
        }
      }
    }
    
  2. In the ModifyMetadata method, register the provider. It is used to handle custom relative links.

    The Provider requires a WidgetType, which is a Dojo widget class used to edit the value of the provider. In this case, it is a standard ValidationTextbox. After running the site, the following dialog box displays an additional Site relative link field.

    After running the site, the following dialog box displays an additional **Site relative link** field

  3. To make relative links work in TinyMCE, set the convert_urls setting to false to prevent TinyMCE from converting the value.

    config.Default()
      .ContentCss(locator.GetInstance<IVirtualPathResolver>().ToAbsolute("~/static/css/editor.css"))
      .BodyClass("custom_partner_body_class")
      .AddPlugin("code")
      .InitializationScript("alloy/advancedTinyMCEConfig")
      .AddSetting("convert_urls", false);
