=head1 NAME

arap.pl - helper functions or customer/vendor retrieval

=head1 SYNOPSIS

 check_name('vendor')

=head1 DESCRIPTION

Don't use anyting in this file without extreme care, and even then be prepared for massive headaches.

It's a collection of helper routines that wrap the customer/vendor dropdown/textfield duality into something even complexer.

=head1 FUNCTIONS

=head2 check_name customer|vendor

check_name was originally meant to update the selected customer or vendor. The
way it does that has generted more hate than almost any other part of this
software.

What it does is:

=over 4

=item *

It checks if a vendor or customer is given. No failsafe, vendor fallback if
$_[0] is something fancy.

=item *

It assumes, that there is a field named customer or vendor in $form.

=item *

It assumes, that this field is filled with name--id, and tries to split that.
sql ledger uses that combination to get ids into the select keys.

=item *

It looks for a field selectcustomer or selectvendor in $form. sql ledger used
to store a copy of the html select in there. (again, don't ask)

=item *

If this field exists, it looks for a field called oldcustomer or oldvendor, in
which the old name--id string was stored in sql ledger, and compares those.

=item *

if they don't match, it will set customer_id or vendor_id in $form, load the
entry (which will clobber everything in $form named like a column in customer
oder vendor) and return.

=item *

If there was no select* entry, it assumes that vclimit was lower than the
number of entries, and that an input field was generated. In that case the
splitting is omitted (since users don't generally include ids in entered names)

=item *

It looks for a *_id field, and combines it with the given input into a name--id
entry and compares it to the old* entry. (Missing any of these will instantly
break check_namea.

=item *

If those do not match, $form->get_name is called to get matching results.
get_name only matches by *number and name, not by id, don't try to get it to do
so.

=item *

The results are stored in $form>{name_list} but a count is returned, and
checked.

=item *

If only one result was found, *_id, * and old* are copied into $form, the entry
is loaded (like above, clobbering)

=item *

If there is more than one, a selection dialog is rendered

=item *

If none is found, an error is generated.

=back

=head3 I built a customer/vendor box somewhere and it doesn't work, what's wrong?

Make sure a select* field is given if and only if you render a select box. The
actual contents are ignored, but recognition fails if not present.

Make sure old* and *_id fields are set correctly (name--id form for old*). They
are necessary in all steps and branches.

Since get_customer and get_vendor clobber a lot of fields, make sure what
changes exactly.

=head3 select- version works fine, but things go awry when I use a textbox, any idea?

If there is more than one match, check_name will display a select form, that
will redirect to the original C<nextsub>. Unfortunately any hidden vars or
input fields will be lost in the process unless saved before in a callback.

If you still want to use it, you can disable this feature, like this:

  check_name('customer', no_select => 1)

In that case multiple matches will trigger an error.

Otherwise you'll have to care to include a complete state in callback.
