Post Relationship Helps Avoid Content Duplication and Ensure Consistency<\/h2>\n\n\n\n

Let’s look at an example to understand the power of post relationship. We’ll build a website for events. Each “event” will list several “speakers”. Of course, each speaker can appear in different events.<\/p>\n\n\n\n

\"\"
Events with one common speaker<\/figcaption><\/div><\/figure>\n\n\n\n
<\/div>\n\n\n\n

You could build this website with a single custom type<\/a> called “events” and list the speakers in a table.<\/p>\n\n\n

\n
\"\"
Events content in editing<\/figcaption><\/div><\/figure>\n<\/div>\n\n\n
<\/div>\n\n\n\n

Now, let’s say that you want to update the image of a speaker. How do you do this? Without using post relationship, you’ll need to edit each of the events where this speaker is showing. If your site only has a few pages, that’s not a big deal. But what if your site lists thousands of events and speakers?<\/p>\n\n\n\n

Post relationship solves this problem. There will be only one entry for each speaker. This entry will include all the details of a speaker. Different events featuring this speaker will only include a pointer to it. When anything changes in the speaker, it immediately shows in all the events that include it.<\/p>\n\n\n

\n
\"\"
Multiple events linking to the same speaker<\/figcaption><\/div><\/figure>\n<\/div>\n\n\n
<\/div>\n\n\n\n

If we build this site with post relationship, we can do a lot more than only list the speakers for each event.<\/p>\n\n\n\n

\n
\n
\"\"<\/a>
Speaker page<\/figcaption><\/div><\/figure>\n<\/div><\/div>\n\n\n\n
\n

Create pages for speakers, listing the events they speak in<\/h4>\n<\/div>\n<\/div>\n\n\n\n
\n
\n
\"\"<\/a>
Events search by speaker<\/figcaption><\/div><\/figure>\n<\/div><\/div>\n\n\n\n
\n

Allow to search for events according to speaker (and vice versa)<\/h4>\n<\/div>\n<\/div>\n\n\n\n
\n
\n
\"\"<\/a>
Export \/ Import<\/figcaption><\/div><\/figure>\n<\/div><\/div>\n\n\n\n

Easily export and import events and speakers<\/h4>\n<\/div>\n<\/div>\n\n\n\n
