Version: 4.0.5 Reporter: James Catt —
This isn’t a huge issue as the tag output is still working as expected, and it only seems to happen with a specific channel/field (so I can’t rule out that it’s something wonky with my site), but I’d like to get to the bottom of it if possible.
Here’s my template:
{exp:channel:entries channel="my_channel"}
{my_relationship_field}
{my_relationship_field:my_file_field}
{!-- some code here, but the error still displays even if this is empty --}
{/my_relationship_field:my_file_field}
{/my_relationship_field}
{/exp:channel:entries}As I mentioned, the output from the template is correct, but I’m getting the following PHP Error:
Notice
Undefined index: field_id_21
ee/legacy/libraries/channel_entries_parser/components/Custom_field_pair.php, line 138
Severity: E_NOTICEfield_id_21 == my_file_field (I get the same error repeated for every file field referenced)
The strange thing is that I have the same pattern in another template (with a different parent channel + relationship field, but the same child channel + file field), but I’m not getting the same error message.
I’ve looked at the debugging output but I’m not seeing any obvious issues.
