Installation:
1) Unpack the package and create a database
2) Create a Database-User (e.g. phpRealGallery)
3) Create the tables "galleries" and "images". I have included a dump-file for Postgre (pg.sql).
galleries(gid(pkey), title, text)
images(iid(pkey), gid, file, title, text, tech, size, date, price)
4) Grant the select-right for these tables to the DB-User (the pg-dump-file does it for phpRealGallery)
5) Put data into the tables and upload the images
6) Set the appropriate values for the DB-Connection in prepend.php3 (I have included db_pgsql.inc, db_mysql.inc and db_odbc.inc,
if you have nstallled the PHP Base Library on your Server, you also can use this one. Therefore copy the prepend.php3 and
local inc into your directory, set the right include-path and db_* file in prepend.php3 and configure your database-connection
in local.inc.
6) Read the Documentation
Documentation:
Description:
phpRealGallery is a gallery-tool with a Database-Backend wich can display several galleries,
thumbnails of each gallery and the images in real-size with several information-fields (title, text, size, tech, date, price).
The class should be embedded in the body-tag of an HTML-File. It produces valid XHTML 1.0 code.
Methods:
main
Synopsis
$error=$gallery-object->main()
Purpose
Show overview of galleries
show_gallery
Synopsis
$error=$gallery-object->show_gallery($gid)
Purpose
Show thumbnails of specified gallery
Arguments
$gid
The ID of the selected gallery
show_image
Synopsis
$error=$gallery-object->show_image($iid)
Purpose
Show specified image in real-size with additional information
Arguments
$iid
The ID of the selected image
Properties:
img_path
Synopsis
$gallery_object->img_path=string
Purpose
Specifies the directory where the images are stored
thumbnails_per_row
Synopsis
$gallery_object->thumbnails_per_row=int
Purpose
Specifies the number of thumbnails per row
file_name
Synopsis
$gallery_object->file_name=basename($PHP_SELF);
Purpose
Specifies the Name of the gallery file
thumbnail_size
Synopsis
$gallery_object->thumbnail_size=int
Purpose
Specifies the Thumbnail-Size in percent of the original size
Example Usage:
require("./class.gallery.php");
$g=new Gallery;
$g->img_path="./img/gallery/"; (can also be an absolute path, or a ftp- or http-server)
$g->thumbnails_per_row=3;
$g->file_name=basename($PHP_SELF);
$g->thumbnail_size=25;
IF($show_gallery) $g->show_gallery($show_gallery);
ELSEIF($show_image) $g->show_image($show_image);
ELSE $g->main();
The Design can be changed by CSS with the following classes:
a.thumbnail
a.nav_button
table.thumbnail
tr.thumbnail
td.thumbnail
img.nav_button
img.thumbnail
img.gallery
Graphic-Navigation-Buttons:
Put the following files in the image-directory:
left.gif // for link-arrows
left2.gif // for non-link-arrows
right.gif
right2.gif
up.gif
Todo:
+ Storage of Images in Database ?
+ Admin-Interface with File-Upload
+ Real Thumbnail-Generation for jpg, gif and png (Either gif or png, depends on GD-Version)
+ Multi-Language Support
