WEB 5 PLAN ,
WEB 6 PLAN .
At Alden Hosting we eat and breathe Java! We are the industry leader in providing
affordable, quality and efficient Java web hosting in the shared hosting marketplace.
All our sites run on our Java hosing platform configured for
optimum performance using Java 1.6, Tomcat 6.0.X, MySQL 5.0.x, Apache 2.2.xx and web
application frameworks such as Struts, Hibernate, Cocoon, Ant, etc.
We offer only one type of Java hosting - Private Tomcat. Hosting accounts on the Private
Tomcat environment get their very own Tomcat server. You can start and re-start
your entire Tomcat server yourself.
Forms Data Format (FDF) is a format for handling
forms within PDF documents. You should read the documentation at
http://partners.adobe.com/asn/acrobat/forms.jsp
for more information on what FDF is and how it is used in general.
The general idea of FDF is similar to HTML forms. The difference is
basically the format how data is transmitted to the server when the submit
button is pressed (this is actually the Form Data Format) and the format
of the form itself (which is the Portable Document Format, PDF).
Processing the FDF data is one of the features provided by the fdf
functions. But there is more. One may as well take an existing PDF form
and populated the input fields with data without modifying the form
itself. In such a case one would create a FDF document
(fdf_create()) set the values of each input field
(fdf_set_value()) and associate it with a PDF form
(fdf_set_file()). Finally it has to be sent to the
browser with MimeType application/vnd.fdf. The Acrobat
reader plugin of your browser recognizes the MimeType, reads the
associated PDF form and fills in the data from the FDF document.
If you look at an FDF-document with a text editor you will find a
catalogue object with the name FDF. Such an object may
contain a number of entries like Fields,
F, Status etc..
The most commonly used entries are Fields which points
to a list of input fields, and F which contains the
filename of the PDF-document this data belongs to. Those entries are
referred to in the FDF documentation as /F-Key or /Status-Key.
Modifying this entries
is done by functions like fdf_set_file() and
fdf_set_status(). Fields are modified with
fdf_set_value(), fdf_set_opt() etc..
You need the FDF toolkit SDK available from
http://partners.adobe.com/asn/acrobat/forms.jsp.
As of PHP 4.3.0 you need at least SDK version 5.0.
The FDF toolkit library is available in binary form only,
platforms supported by Adobe are Win32, Linux, Solaris and AIX.
Note:
If you run into problems configuring PHP with fdftk support, check
whether the header file fdftk.h and the library
libfdftk.so are at the right place.
The configure script supports both the directory structure of the
FDF SDK distribution and the usual DIR/include /
DIR/lib layout, so you can point it either
directly to the unpacked distribution directory or put the header
file and the appropriate library for your platform into e.g.
/usr/local/include and
/usr/local/lib and configure with
--with-fdftk=/usr/local.
Note to Win32 Users:
In order for this extension to work, there are
DLL files that must be available to the Windows
system PATH. See the FAQ titled "How do I add my PHP directory to the PATH
on Windows" for information on how to do this. Although copying DLL
files from the PHP folder into the Windows system directory also works
(because the system directory is by default in the systems
PATH), it is not recommended.
This extension requires the following files to be in the
PATH:fdftk.dll
Most fdf functions require a fdf resource
as their first parameter. A fdf resource
is a handle to an opened fdf file. fdf
resources may be obtained using fdf_create(),
fdf_open() and fdf_open_string().
The constants below are defined by this extension, and
will only be available when the extension has either
been compiled into PHP or dynamically loaded at runtime.
The following examples shows just the evaluation of form data.
Example 1. Evaluating a FDF document
<?php // Open fdf from input string provided by the extension // The pdf form contained several input text fields with the names // volume, date, comment, publisher, preparer, and two checkboxes // show_publisher and show_preparer. $fdf = fdf_open_string($HTTP_FDF_DATA); $volume = fdf_get_value($fdf, "volume"); echo "The volume field has the value '<b>$volume</b>'<br />";
$date = fdf_get_value($fdf, "date"); echo "The date field has the value '<b>$date</b>'<br />";
$comment = fdf_get_value($fdf, "comment"); echo "The comment field has the value '<b>$comment</b>'<br />";
if (fdf_get_value($fdf, "show_publisher") == "On") { $publisher = fdf_get_value($fdf, "publisher"); echo "The publisher field has the value '<b>$publisher</b>'<br />"; } else echo "Publisher shall not be shown.<br />";
if (fdf_get_value($fdf, "show_preparer") == "On") { $preparer = fdf_get_value($fdf, "preparer"); echo "The preparer field has the value '<b>$preparer</b>'<br />"; } else echo "Preparer shall not be shown.<br />"; fdf_close($fdf); ?>
