PHP: fdf_create

Description

resource fdf_create ( void )

The fdf_create() creates a new FDF document. This function is needed if one would like to populate input fields in a PDF document with data.

Пример 1. Populating a PDF document

<?php $outfdf = fdf_create(); fdf_set_value($outfdf, "volume", $volume, 0); fdf_set_file($outfdf, "http:/testfdf/resultlabel.pdf"); fdf_save($outfdf, "outtest.fdf"); fdf_close($outfdf); Header("Content-type: application/vnd.fdf"); $fp = fopen("outtest.fdf", "r"); fpassthru($fp); unlink("outtest.fdf"); ?>

For fdf_save you need to provide the complete path, such as :fdf_save($outfdf,"c:/inetpub/wwwroot/temp_sites/fdf/outtest.fdf"); and not only outtest.fdf.

<?php

$outfdf = fdf_create();

$volume = "test";

fdf_set_value($outfdf, "volume", $volume, 0);



fdf_set_file($outfdf, "http://localhost/webapps/volume.pdf");

Header("Content-type: application/vnd.fdf");

fdf_save($outfdf);

fdf_close($outfdf);



?>



This works for IE 5.5+  



It will populate the fields and open the resulting pdf for you, without having to create an fdf file and adding the open script to the pdf...

Header("Content-type: application/vnd.fdf"); simply does not work in IE. The easiest method to automatically load the fdf file is to open the 'pdf' file via php. With use of Acrobat 

document -> page action -> page open -> add -> javascript

and paste the following into the pdf file:



this.importAnFDF("my_fdf_file.fdf");



This will auto-load the fdf contents

I thought the following might save someone a lot of time. The example fdf snippet above, namely:



<?php

$outfdf = fdf_create();

fdf_set_value($outfdf, "volume", $volume, 0);



fdf_set_file($outfdf, "http:/testfdf/resultlabel.pdf");

fdf_save($outfdf, "outtest.fdf");

fdf_close($outfdf);

Header("Content-type: application/vnd.fdf");

$fp = fopen("outtest.fdf", "r");

fpassthru($fp);

unlink("outtest.fdf");

?>



will not work (or there's at least a big possibility it won't) in IE (version 6 sure and I suspect lower versions as well) if you have session.auto_start on. Apparently, setting a cookie before feeding the fdf to the browser somehow messes it up. It works fine in Netscape though. I spent days on Google before I found a post somewhere about someone else having the same problem. 



The solution? Well, I created a separate directory in the web tree and turned session.auto_start off just for that directory like this:



<Location /new_directory>

    php_admin_flag session.auto_start 0

</Location>



Hope this was useful to somebody.
