Extremely Frustrating Problem, Guys.

[Amps]

Hey everyone, Im trying to write to an XML file (which already has contents) from PHP and add a line BEFORE the closing tag of the XML document.

 

So, using PHP im basically trying to add something before the closing tag of the xml file.

 

I have tried tons of stuff like this:

 

<?php
$file_handle = fopen('db.xml','a'); 
$content=('	<veri>
	<title>Whats your name</title>
	<description>My name is Zacharia</description>
            <emotion>Happy</emotion>
</veri>'); 
fwrite($file_handle,$content); 
fclose($file_handle);
?>

 

and using Fseek like this:

 

fseek($file_handle, -8, SEEK_END);

to get to pointer before the closing tag.

 

All has failed so far, and I really need this to work.

 

Can anyone help?

Is the closing tag on the last line of the file? If so you can do something like this:

<?php
$contents = file('db.xml');
$tmp = $contents[count($contents) - 1]; // save the last line
$contents[count($contents) -1] = 'Your new content';
$contents[] = $tmp;
$fp = fopen('db.xml','w'); // create a new version of the file
foreach ($contents as $line)
    fwrite($fp,trim($line)."\r\n");
fclose($fp);
?>

 

Note: not checked for syntax errors. YMMV

You my friend, are a genius. It worked perfectly.

 

I only have one little problem that has confused me slightly aswell, this is actually a very small problem but maybe someone knows here.

 

Basicaly, im passing 3 variables from flash using the code:

 

on (release) {

    var question = _root.question;

    var answer = _root.answer;

    var emotion = _root.emotion;

    getURL("ai.php", "_blank", "POST");

}

 

Right, that part is fine. It works at passing the variables to PHP. But its then the PHP part:

 

<?php

$question = $_POST["question"]; 

$answer = $_POST["answer"]; 

$emotion = $_POST["emotion"];

$contents = file('db.xml');

$tmp = $contents[count($contents) - 1]; // save the last line

$contents[count($contents) -1] = ' <veri>

<title>$question</title>

<description>$answer</description>

            <emotion>$emotion</emotion>

</veri>';

$contents[] = $tmp;

$fp = fopen('db.xml','w'); // create a new version of the file

foreach ($contents as $line)

    fwrite($fp,trim($line)."\r\n");

fclose($fp);

?>

 

The variables are passed ok, but the added content to the XML file will be something like "<title>$question</title>" instead of "<title>Are you human?</title>"  which is the variable passed.

Try changing:

 

<?php
$question = $_POST["question"]; 
$answer = $_POST["answer"]; 
$emotion = $_POST["emotion"];
$contents = file('db.xml');
$tmp = $contents[count($contents) - 1]; // save the last line
$contents[count($contents) -1] = '   <veri>
      <title>$question</title>
      <description>$answer</description>
            <emotion>$emotion</emotion>
   </veri>';
$contents[] = $tmp;
$fp = fopen('db.xml','w'); // create a new version of the file
foreach ($contents as $line)
    fwrite($fp,trim($line)."\r\n");
fclose($fp);
?>

 

To:

 

<?php
$question = $_POST["question"]; 
$answer = $_POST["answer"]; 
$emotion = $_POST["emotion"];
$contents = file('db.xml');
$tmp = $contents[count($contents) - 1]; // save the last line
$contents[count($contents) -1] = '   <veri>
      <title>'.$question.'</title>
      <description>'.$answer.'</description>
            <emotion>'.$emotion.'</emotion>
   </veri>';
$contents[] = $tmp;
$fp = fopen('db.xml','w'); // create a new version of the file
foreach ($contents as $line)
    fwrite($fp,trim($line)."\r\n");
fclose($fp);
?>

That is happening because you are delimiting your string with single quotes. Variables are not evaluated when enclosed in single quotes, only double quotes. Try this:

<?php
$contents[count($contents) -1] = "   <veri>
      <title>$question</title>
      <description>$answer</description>
            <emotion>$emotion</emotion>
   </veri>";
?>

 

Also, when posting code to this forum use

tags, not

tags.
