SafeCracker: «You must specify a valid entry to edit.»

Question

SafeCracker gives me a Error after submitting an edit-form…

{exp:safecracker channel='xy' … entry_id='{segment_3}'}

• The URL contains the entry_id @ segment_3
• All field-values are included in their respective custom fields
• If I look into the rendered HTML, the entry_id is all over the place like: <input type="hidden" name="entry_id" value="15771"> and others (RET, URI) … ditto for the correct values for author_id, channel_id, site_id etc. (see below)

If I submit the form, the following error gets displayed.

You must specify a valid entry to edit.

BUT an interesting fact: the entry gets saved anyway!

System: EE 2.5.5

EDIT: All the hiddenFields:

<input type="hidden" name="ACT" value="21">
<input type="hidden" name="RET" value="http://domain.com/dir/dir2/15771">
<input type="hidden" name="URI" value="dir/dir2/15771">
<input type="hidden" name="XID" value="">
<input type="hidden" name="return_url" value="dir/dir2/success/15771">
<input type="hidden" name="author_id" value="1">
<input type="hidden" name="channel_id" value="16">
<input type="hidden" name="entry_id" value="15771">
<input type="hidden" name="site_id" value="1">
<input type="hidden" name="return" value="dir/dir2/success/15771">
<input type="hidden" name="allow_comments" value="y">

Answer 1

You write:

The URL contains the entry_id @ segment_3

But

The return url has "success" as segment_3.

<input type="hidden" name="return" value="dir/dir2/success/15771">

This is not a valid entry.

You can either change

 {exp:safecracker channel='xy' … entry_id='{segment_3}'}

to

 {exp:safecracker channel='xy' … entry_id='{segment_4}'}

Or change the url return path to something like

<input type="hidden" name="return" value="dir/dir2/15771/success">

Answer 2

Are you passing the entry id as ENTRY_ID in the return?

{exp:safecracker channel="channel_name" return="channel_name/edit/ENTRY_ID" entry_id="{segment_3}"}
