How do I enable editing of entries with a front-end form? Users can currently submit entries using a form on the front-end. How would I go about showing the current logged in user's existing entries and allow them to edit them through another front-end form?
Add another hidden input field &quot;entryId&quot; to your form. There's nice example code in the Docs:

You can modify the form to save existing entries by adding an “entryId” hidden input to the form:
&lt;input type=&quot;hidden&quot; name=&quot;entryId&quot; value=&quot;{{ entry.id }}&quot;&gt;
