Problem with coding the writing thing..

bubekson

Hi,

I have two php scripts: 1st to read the xml file and another to write modified data.

Here is the code of the first one:

<?
$xml = simplexml_load_file("test.xml");

foreach($xml->children() as $child)
  {
  echo "<form name=Edit2 action=parser.php method=post><td><tr></tr><tr><td width=78><textarea rows=5 cols=30 name=" . $child->getName() . ">" . $child . "</textarea></td><td width=78><input type=submit value=Submit ></td></tr></form>";
  }
?>

=So all of child are the separate forms and that was my plan, and it is not a problem.

But when I go further and start coding the second one - I have the problem.
I wanted to do exacly same structure of code with the "foreach" construct, but it is not working at all.

<?php 
$xml = simplexml_load_file("test.xml");

foreach($xml->children() as $child) 
if (!empty($_POST[$child->getName()])) { 
	$var = $_POST[$child->getName()];
    $var = $child;// THIS IS MY PROBLEMATIC LINE!


foreach($xml->children() as $child)//testing if script made changes
  {
  echo $child->getName() . ": " . $child . "<br />";
  }


}
?>

As you can see I wanted to have '$child->getName()' as the posted name from the form . But it isn't working.

I'm not thinking good in this second script for sure..

The '$child->getName()' is the posted name and in textarea is the '. $child .' . My thinking is that when the name is posted script will modify the '. $child .'...

Please answer. ;]

I've added the '$xml->children() = $child;' to this script so it looks like this:

<?php 
$xml = simplexml_load_file("test.xml");

foreach($xml->children() as $child) 
if (!empty($_POST[$child->getName()])) {
	$child = $_POST[$child->getName()];

    $xml->children() = $child;//added line

$xml->getName() . "<br />";


foreach($xml->children() as $child)
  {
  echo $child->getName() . ": " . $child . "<br />";
  }


}
?>

But the answer is 'Fatal error: Can't use method return value in write context in..'

What can be done?? I've searched everywhere and couldn't find a good solution.

Everything works fine except two little "()" beyond the children in "$xml->children() = $child;" line.

When I cut this the script makes the new line in result, so the rest of the code is good.

Please give me the sign.. 😕
