Couple of things1/ get rid of this line: @$cat=$HTTPGETVARS'cat'; // Use this line or above line if registerglobal is offits really not required.2/ take the @signs off the mysql lines. It suppresses the errors that you will need in case it all goes wrong.3/ noticia is just the simple variable assigned to hold the results of the query which are returned as an array.You could call it anything you like just as arron did in post #7, he called it $row.while ($row = $result-fetchassoc).

Using SOAP poses a problem when you want to make such a solution work with the free Adobe Reader. In the past, Adobe had an ODBC interface built into the Windows version of Acrobat/Reader (named the ADBC interface), but that had the same problem as far as Reader goes, and was removed back in the days of Acrobat 9. So what can be done to connect a PDF form to a database in a way that also works with the free Reader?

Be prepared for a long post that is of the most part about PHP running on a web server. You will need a web server that supports PHP if you want to follow along. I assume you know how to install PHP scripts on your web server, and also how to create PDF forms that submit data to a server.The solution is to “talk” back and forth between the PDF form and the web server using XFDF. XFDF is the XML version of FDF, the “Form Data Format”, which is based on the PDF format (it’s a stripped down version of PDF). The FDF format can be used to submit form data from a PDF form to a web server, and to receive information back from the server. Reading and writing FDF is a complex task, and Adobe used to have the, which helped with these tasks, but this toolkit has not been updated since Acrobat 7 and is not supported by Adobe anymore. The XFDF format can do almost anything that can be done with FDF, but in a much easier to parse and to write format.To take a look at what FDF and XFDF files look like, it’s easy to create them by exporting data from a PDF form using Adobe Acrobat: In Acrobat DC, load a form and then search for “export” in the tools search bar and select “Export data from a form file” in the “Prepare Form” cateogry.

You can then select the output format on the “Save” dialog (use either FDF or XFDF). Here is a sample FDF file (slightly reformatted to make it easier to read). Test dataFor anybody with at least some XML background, it’s obvious that the XFDF file is much easier to understand and to parse. The FDF format is described here:, and the XFDF format is described in this document: (I don’t have a link to the original Adobe hosted document, I also don’t know how reliable or trustworthy this service is).Let’s take a look at what the XFDF document above contains: There is one top level XML node (as required by the XML standard) called “xfdf”, which contains three nodes: f, fields and ids – for now we can ignore the f node (which is just a reference to the PDF file this XFDF data came from – should be imported into), and the ids node (that’s the document ID). The interesting “stuff” is happening in “fields”: It contains a list of field nodes – each one describing the data stored in a specific field.

Each field node has a “name” attribute, and contains a value node with the actual data. In the example above, we can see that there is one field in the document named “Field 1”, which contains the string “test data”.

Pretty simple.As mentioned before, this file was exported from a form, so we can see what data was actually entered in the form, but the same approach can also be used to import data into the form. I can for example change the value node to now contain the string “new data”. When I now use the import function in Acrobat, I can fill my form with this updated data.What we’ve done so far by manually importing and exporting can be automated. To export data we can for example use the “submit a form” action on a button – or the. Both methods allow us to specify the format we want to submit our data in.

We are looking at XFDF, so let’s select XFDF as the form’s submission format.Data is usually submitted to a web server (it can also be emailed, but for automation purposes, that just complicates things). Before we can actually submit the data from a form, we need to take a look at how we can receive that data on the server. The following example will use PHP on an Apache server, but you should be able to adapt the solution to any other server setup.The most simplistic PHP script that can accept data but without actually processing the data (it’s only stored on a variable that we never use again) is this. When we now submit our form data to this PHP script on a web server (I assume you know how to setup PHP scripts on your server), and we click on the submit button in Adobe Acrobat, we get a new PDF file that reads “Received some data.”. This looks like our data made it to the server – but we don’t yet have a way to get information back.When we make things a little bit more complex, we can actually see the submitted XFDF. What are we doing here? The data that is sent back (which is just text) gets interpreted by Acrobat as HTML, this means that it will filter out all the XML.

In the additional line of PHP code we just added, the “. Updated ValueEOT;echo $returnXFDF;?Besides the hardcoded string, we are also setting the content type of the reply to “application/vnd.adobe.xfdf”, which tells either the browser, or Acrobat (or the free Adobe Reader) that the reply contains XFDF data.When we now submit our form, the server will reply with an updated value for “Field 1”, and Acrobat in turn will update that field’s value. SecurityIf you followed along so far, you’ve probably noticed that Acrobat will not just allow you to submit data to a web site, it will prompt the user to select if the operation should be allowed once, or forever, and will then force the user to actually click on the submission button again to actually send the data to the server. When you create a solution based on this technology, please inform your users about what to expect when clicking the submission button for the first time, and how to proceed. Reading and Setting DataAt this point, we have almost all the parts that we need to create a solution that reads and processes information submitted by the form, and to reply with a data record that Acrobat (or Reader) can use to populate fields in a form. To make things comparable to the SOAP implementation I presented earlier, I will again create and retrieve a unique number from a database so that e.g. A form can be labeled with that unique number.

You may want to for some background information.What is still missing is only plain PHP – nothing specific to Acrobat or the PDF environment: We need to parse the XFDF data we receive from Acrobat (remember, this is just XML, so anything that can parse XML will do), and we need to create a response in valid XFDF with potentially updated information.Here is a PHP script that adds these two missing features.
