I’m using a channel form to allow readers to submit letters to the editor that can include pictures. Here’s the (redacted) code:
{exp:channel:form channel="{my_channel}" category="37" return="/site/page/5569" status="closed"}
<textarea name="body" cols="50" rows="20" class="rich_text"></textarea>
{field:pictures}
<input type="submit" value="Post" />
{/exp:channel:form}The form seems to work OK. You can enter photos and captions just as you would in the the control panel. But when I save the form, and go to edit the entry in the control panel, all of the entry is there, except for the grid contents, which are empty.
