i have multi page forms , which i have connected to mysql, now what i want is to write data of forms in xml whenever submitted but i want it to write a new xml file everytime.

Is it possible? If yes then how? please provide a script if any one can, it will be highly appreciated.

Thank you

Unfortunately, you'll have to write it yourself, but look into PHP's xml functions.

You could just emit xml data using PHP's print or echo commands.

I googled "php form to xml" and found a bunch of examples but nothing exactly what you need.
It should be pretty easy to make a quick and dirty script to something like this.

First note that this is particular dangerous because your going $_POST -> File and if the file is in a public place it can be a problem. Be sure to store them outside an execution folder.

PHP Code:

<?php
$doc = new_xmldoc('1.0');
$root = $doc->add_root('data');
$data = $root->new_child('data','');
foreach($_POST as $k=>$v){
$data->new_child($k,$v);
}
file_put_contents($_POST['filename'],$doc->dumpmem());
?>

So this dumps the $_POST info in to a file that you passed to it via $_POST['filename'] using xmldoc. Untested.

I do understand that we can write data into xml. But i want tocreate a new xml file everytime data is submitted , is it possible?

[dgreenhouse]

Of course it's possible.

Just create a new file with a slightly different name each time - if that's what you need.

You could use tempnam(), tmpfile() or some other file naming scheme of your own design.

The directory you create the file in must be writable by the user that the webserver is running as.

That's wonderful. but it would be gr8 if you could write down a small example. It would be a great help.

Or if it is possible to store data of multi-page form in sessions and database also, which in the end will create xml and pass the same data into database as well?

[dgreenhouse]

What do you have already?

[t-soft]

i have multi page form whichstores data in mysql database. Now i am not able to save data from MySql to XML.
Though everytime form is submitted i would require a new XML file to be created.

Thanx in advance.

Also, you kept saying "database" so I assume you want to store the values in the database.

In the database table, I'd use a "blob" field to store the data.

For multi-page forms, I'd either track the variables in session variables or if cookies aren't set, you'll need to either use URL cookies (really ugly)
or save the inter-page variables in a temporary variables' table.

If a temporary table, I'd opt for serializing the values keyed on the form id and ip address of the visitor.
(see: php's serialize() and unserialize() functions)

The temporary variables table uses a blob field also for the serialized values and the structure would be something like:
form_id (varchar(16)), ip_addr (char(15) for ipv4), variables (blob).

You've provided very little on the program structure, so I really can't help beyond the former and the following.
(I can't do your work for you.)

What is the logic of saving a new XML page?

Do you know how to create an XML page by just using code?

Why don't you just create a custom XML wrapper?

Maybe something like:

Code:

<?xml version="1.0" encoding="ISO-8859-1"?>
<form id="form_id">
  <variables>
    <variable name="variable1">variable1 value</variable>
    <variable name="variable2">variable2 value</variable>
  </variables>
</form>

Or something simpler?

Example:

Code:

<?php

if (isset($_POST['submit'])) {

  $xml = '<?xml version="1.0" encoding="ISO-8859-1"?>'."\n";
  $xml .= '<form id="' . $_POST['form_id'] . '">' ."\n";
  $xml .= '<variables>'."\n";
  $xml .= '<variable name="var1">' . $_POST['var1'] . '</variable>' ."\n";
  $xml .= '<variable name="var2">' . $_POST['var2'] . '</variable>' ."\n";
  $xml .= '<variable name="var3">' . (isset($_POST['var3']) ? 'on' : '') . '</variable>' ."\n"; // note test for checkbox
  $xml .= '</variables>'."\n";
  $xml .= '</form>';

header ("content-type: text/xml");
print $xml;
exit;
}
