53 =head1 NAME
55 C4::Suggestions - Some useful functions for dealings with aqorders.
57 =head1 SYNOPSIS
59 use C4::Suggestions;
61 =head1 DESCRIPTION
63 The functions in this module deal with the aqorders in OPAC and in librarian interface
65 A suggestion is done in the OPAC. It has the status "ASKED"
67 When a librarian manages the suggestion, they can set the status to "REJECTED" or "ACCEPTED".
69 When the book is ordered, the suggestion status becomes "ORDERED"
71 When a book is ordered and arrived in the library, the status becomes "AVAILABLE"
73 All aqorders of a borrower can be seen by the borrower itself.
74 Suggestions done by other borrowers can be seen when not "AVAILABLE"
76 =head1 FUNCTIONS
78 =head2 SearchSuggestion
80 (\@array) = &SearchSuggestion($suggestionhashref_to_search)
82 searches for a suggestion
84 return :
85 C<\@array> : the aqorders found. Array of hash.
86 Note the status is stored twice :
87 * in the status field
88 * as parameter ( for example ASKED => 1, or REJECTED => 1) . This is for template & translation purposes.
