PHP help

[MrPinkPanther]

I've got some PHP which essentially writes out some of the details about my objects in an external app into a plist which is basically XML. The only problem is that it isnt writing! It could be a problem with the app but its more than likely PHP because I'm a PHP noob, can anyone see any errors?

<?php
  
  $Object1 = $_POST['Object1']; 
    $Object1x = $_POST['Object1x']; 
    $Object1y = $_POST['Object1y']; 

    $Object2 = $_POST['Object2']; 
    $Object2x = $_POST['Object2x']; 
    $Object2y = $_POST['Object2y']; 

    $Object3 = $_POST['Object3']; 
    $Object3x = $_POST['Object3x']; 
    $Object3y = $_POST['Object3y']; 

    $Object4 = $_POST['Object4']; 
    $Object4x = $_POST['Object4x']; 
    $Object4y = $_POST['Object4y']; 

    $Object5 = $_POST['Object5']; 
    $Object5x = $_POST['Object5x']; 
    $Object5y = $_POST['Object5y']; 

$file = 'Values.plist';
$f_op = fopen($file);

$string = '<?xml version="1.0" encoding="UTF-8"?>';
fwrite($f_op, $string);

$string = '<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">';
fwrite($f_op, $string);

$string = '<plist version="1.0">';
fwrite($f_op, $string);

$string = '<dict>';
fwrite($f_op, $string);

$string = '<key>Item1</key>';
fwrite($f_op, $string);
$string = '<string>' . $Object1 . '</string>';
fwrite($f_op, $string);
$string = '<key>Item1x</key>';
fwrite($f_op, $string);
$string = '<string>' . $Object1x . '</string>';
fwrite($f_op, $string);
$string = '<key>Item1y</key>';
fwrite($f_op, $string);
$string = '<string>' . $Object1y . '</string>';
fwrite($f_op, $string);

$string = '<key>Item2</key>';
fwrite($f_op, $string);
$string = '<string>' . $Object2 . '</string>';
fwrite($f_op, $string);
$string = '<key>Item2x</key>';
fwrite($f_op, $string);
$string = '<string>' . $Object2x . '</string>';
fwrite($f_op, $string);
$string = '<key>Item2y</key>';
fwrite($f_op, $string);
$string = '<string>' . $Object2y . '</string>';
fwrite($f_op, $string);

$string = '<key>Item3</key>';
fwrite($f_op, $string);
$string = '<string>' . $Object3 . '</string>';
fwrite($f_op, $string);
$string = '<key>Item3x</key>';

$string = '<string>' . $Object3x . '</string>';
fwrite($f_op, $string);
$string = '<key>Item3y</key>';
fwrite($f_op, $string);
$string = '<string>' . $Object3y . '</string>';
fwrite($f_op, $string);

$string = '<key>Item4</key>';
fwrite($f_op, $string);
$string = '<string>' . $Object4 . '</string>';
fwrite($f_op, $string);
$string = '<key>Item4x</key>';

fwrite($f_op, $string);
$string = '<string>' . $Object5 . '</string>';
fwrite($f_op, $string);
$string = '<key>Item5x</key>';
fwrite($f_op, $string);
$string = '<string>' . $Object5x . '</string>';
fwrite($f_op, $string);
$string = '<key>Item5y</key>';
fwrite($f_op, $string);
$string = '<string>' . $Object5y . '</string>';
fwrite($f_op, $string);

fclose($f_op);

I'm not sure if you can $string = '<?xml version="1.0" encoding="UTF-8"?>'; as wouldn't it close the php connection in the whole file? Not sure...

Edit: THIS IS USELESS:

Show Hide

Edit: Just tested this:

<?php

echo 'yo';

$string = '<?xml version="1.0" encoding="UTF-8"?>';

echo 'rawr';

echo $string;

echo 'meh';

?>

The data "string" contains nothing, and the output of the echo is nothing (result is: yorawrmeh) which would suggest that line does nothing?
I'll try a simple fopen/fclose/fwrite and test it now.

Actually, I just noticed, your fopen is wrong. You forgot to specify a mode http://uk2.php.net/manual/en/function.fopen.php such as

$f_op = fopen( $file, 'w' ); 

where as you just use:

$f_op = fopen($file);

Honestly why don't you just do

<?php
  
  $Object1 = $_POST['Object1']; 
    $Object1x = $_POST['Object1x']; 
    $Object1y = $_POST['Object1y']; 

    $Object2 = $_POST['Object2']; 
    $Object2x = $_POST['Object2x']; 
    $Object2y = $_POST['Object2y']; 

    $Object3 = $_POST['Object3']; 
    $Object3x = $_POST['Object3x']; 
    $Object3y = $_POST['Object3y']; 

    $Object4 = $_POST['Object4']; 
    $Object4x = $_POST['Object4x']; 
    $Object4y = $_POST['Object4y']; 

    $Object5 = $_POST['Object5']; 
    $Object5x = $_POST['Object5x']; 
    $Object5y = $_POST['Object5y']; 

$file = 'Values.plist';
$f_op = fopen($file);

$string = '<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Item1</key>
<string>' . $Object1 . '</string>
<key>Item1x</key>
<string>' . $Object1x . '</string>
<key>Item1y</key>
<string>' . $Object1y . '</string>
<key>Item2</key>
<string>' . $Object2 . '</string>
<key>Item2x</key>
<string>' . $Object2x . '</string>
<key>Item2y</key>
<string>' . $Object2y . '</string>
<key>Item3</key>
<string>' . $Object3 . '</string>
<key>Item3x</key>
<string>' . $Object3x . '</string>
<key>Item3y</key>
<string>' . $Object3y . '</string>
<key>Item4</key>
<string>' . $Object4 . '</string>
<key>Item4x</key>
<string>' . $Object4x . '</string>
<key>Item4y</key>
<string>' . $Object4y . '</string>
<key>Item5</key>
<string>' . $Object5 . '</string>
<key>Item5x</key>
<string>' . $Object5x . '</string>
<key>Item5y</key>
<string>' . $Object5y . '</string>';

fwrite($f_op, $string);
fclose($f_op); 
?>

Ok, cheers, +Rep. Can anyone shed some more light onto this and tell me how I might go about fixing it.

EDIT: CHEERS BLOB!

Did what Blob gave work? If not, check my new new edit.

It didn't but now it does thanks to you! I love you both lol.

No problem, good luck with whatever you're doing.

[MrPinkPanther]

Cheers! Actually, while I'm at it and rather than creating a new thread in the future I have one more question. How can I add or remove users?

E.G. In the application below up to 3 users can join. Currently User1 and User3 are occupied but not User2.

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> 
<plist version="1.0"> 
<dict> 

<key>User1</key> 
<string>George</string>
<key>User2</key>
<string></string> 
<key>User3</key>
<string>Ryan</string> 

</dict>
</plist>

How could I do it so when someone new joins then their name is sent via POST to fill the User2 String and then when they leave a message is sent via POST so they are removed again.

[Jam-ez]

Well I'm not sure what they're leaving but when they're logging in do something like:

$username = $_POST['username'];

// then if we use that to say..

echo '<key>User1</key> 
<string>George</string>
<key>User2</key>
<string>' . $username . '</string> 
<key>User3</key>
<string>Ryan</string>'; 

You'd have to clarify more what you mean... if you wanted me to help more - or just have a go and post what you get.

Havent tested it, but try it.

<?php
$objNum = 5;

$file = 'Values.plist';

$string = '<?xml version="1.0" encoding="UTF-8"?>';
$string .= '<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">';
$string .= '<plist version="1.0">';

$string .= '<dict>';

for( $i = 1; $i < $objNum; $i++ )
{
    $obj = $_POST[ 'Object' . $i ];
    $objX = $_POST[ 'Object' . $i . 'x' ];
    $objY = $_POST[ 'Object' . $i . 'y' ];
    
    $string = '<key>Item' . $i . '</key>';
    $string .= '<string>' . $obj . '</string>';
    
    $string .= '<key>Item' . $i . 'x</key>';
    $string .= '<string>' . $objX . '</string>';
    
    $string .= '<key>Item' . $i . 'y</key>';
    $string .= '<string>' . $objY . '</string>';
}

$string .= '</dict>';

$handle = fopen( $file );
fwrite( $handle, $string );
fclose( $handle );
?>
