function child_records_config

[zibrahim]

Hi there,
Anyone knows how to use this child_records_config function in the __global hooks?
I want to change the number of records in the child table from the default 10 to 20.
I understand that this function is newly added in 22.14
Appreciate if someone can share the syntax as I couldn't find it in the forum or the appgini website.
Thanks.

Hi Zibrahim,

Take a look at this link:
https://bigprof.com/appgini/help/advanc ... rds_config

I do not think it will help changing 10 to 20, might be wrong though.

To do what you want there is a topic on how to increase to more than 10:

Hi Zibrahim, sure you can:

Code: Select all

function child_records_config($childTable, $childLookupField, &$config)
{
  $rpp = 20;
  array_walk($config, function (&$t) use($rpp) { array_walk($t, function (&$cn) use($rpp) { $cn["records-per-page"] = $rpp; }); });
}

Thanks Jan. It works flawlessly!
I believe it is not as straight forward like the init function, right?
Need to figure out how to set some parent and child table combinations with the specific records per page value...
Thanks again.

It is straight forward.

$config contains settings for all tables, not just for one table (as in hooks/TABLENAME.php / TABLENAME_init(...)-function).

You can modify the code above and do changes for certain tables/fields, only.

Code: Select all

function child_records_config($childTable, $childLookupField, &$config)
{
  // example:
  // partners.id    <---- contacts.partner_id
  changeRecordsPerPage($config, "contacts", "partner_id", "partners", 1);
}

Code: Select all

function changeRecordsPerPage(&$config, $tn, $cn, $parentTn, $recordsPerPage = 20)
{
  $cfg = $config[$tn][$cn];
  if (!$cfg) die("Not found: {$tn}.{$cn}");
  if ($cfg["parent-table"] != $parentTn) die("Parent table mismatch");
  $config[$tn][$cn]["records-per-page"] = max(1, $recordsPerPage);
}

Thank you very much Jan !!
