[Koha-cvs] CVS: koha/z3950 search.pl,NONE,1.1

[Paul POULAIN]

Update of /cvsroot/koha/koha/z3950
In directory sc8-pr-cvs1:/tmp/cvs-serv5011/z3950

Added Files:
	search.pl 
Log Message:
really proud of this commit :-)
z3950 search and import seems to works fine.
Let me explain how :
* a "search z3950" button is added in the addbiblio template.
* when clicked, a popup appears and z3950/search.pl is called
* z3950/search.pl calls addz3950search in the DB
* the z3950 daemon retrieve the records and stores them in z3950results AND in marc_breeding table.
* as long as there as searches pending, the popup auto refresh every 2 seconds, and says how many searches are pending.
* when the user clicks on a z3950 result => the parent popup is called with the requested biblio, and auto-filled

Note :
* character encoding support : (It's a nightmare...) In the z3950servers table, a "encoding" column has been added. You can put "UNIMARC" or "USMARC" in this column. Depending on this, the char_decode in C4::Biblio.pm replaces marc-char-encode by an iso 8859-1 encoding. Note that in the breeding import this value has been added too, for a better support.
* the marc_breeding and z3950* tables have been modified : they have an encoding column and the random z3950 number is stored too for convenience => it's the key I use to list only requested biblios in the popup.
