[RESOLVED] retaining XML structure, please help!

[camoconnell_com]

Hello there,

I need help urgently on this one, so if anyone could assist i'd be so thankful,

The Problem;
i'm adding new entries from a form into a XML file, so i need to keep the structure of the XML intact, as you can see below, the new entries need to fit between the olddata ($olddata) and the </gallery> tag. I'm having differculties acheiving this;

<gallery>
<imageurl>image_006.jpg</imageurl>
<captiontext>this is a image</captiontext>
<imageurl>image_007.jpg</imageurl>
<captiontext>this is a image</captiontext>

New Entries need to enter here<<

</gallery>

this is my current PHP

[code=php]<?php

$Submit = $_POST['Submit'];

if(isset( $Submit )) {

$Submit     = $_POST["Submit"];
$post         = $_POST["edit_chi"];
$post		= ereg_replace('[^A-Za-z0-9 \@\.\-\/\'_\~\:"<=>#|]', "", $post);
$post       	= stripslashes($post);

$filename = "gallery.xml";
$fp = fopen($filename,"r+");
$old_data = fread($fp, 80000);
fclose($fp);

$input = "$post";
$new = str_replace( $old_data$input ,' </gallery>');

$fp = fopen( $filename,"w");
if(!$fp) die("&error =Failed to write!");
fwrite($fp, $new, 800000);
fclose( $fp );

} [/code]

i know it has something to do with the way this is coded;

$input = "$post";
$new = str_replace( $old_data$input ,' </gallery>');

Thank You

Are you running PHP 5? If so, I would do it by using the [man]SimpleXML[/man] functions. (See "Example 2187. Adding elements and attributes" on the above link for a simple example of adding an element.)

Hey NogDog,

unfortunity not, that would've been excellent.

any other clues?

😕

[NogDog]

Maybe something like this (untested {and streamlined a bit})?

<?php
if(!empty($_POST)) {
   $input = ereg_replace('[^A-Za-z0-9 \@\.\-\/\'_\~\:"<=>#|]',
                        stripslashes($_POST["edit_chi"]));

   $filename = "gallery.xml";
   $data = file_get_contents($filename);

   $data = str_replace('</gallery>', "$input\n</gallery>", $data);

   $fp = fopen($filename,"w") or die("&error    =Failed to write!");
   fwrite($fp, $new, 800000);
   fclose( $fp );
}

Heya NogDog

thanks heaps for the streamlined code, but i'm going to stay with this code for the moment. I've added the str_replace you suggested, and it kind of works, BUT the order is out, the new entry enters at the begining of of the file, opposed to where it should be - between the old_data and the </gallery> tag

<?php

$Submit = $_POST['Submit'];

if(isset( $Submit )) {

$Submit     = $_POST["Submit"];
$post         = $_POST["edit_chi"];
$post		= ereg_replace('[^A-Za-z0-9 \@\.\-\/\'_\~\:"<=>#|]', "", $post);
$post       	= stripslashes($post);


$filename = "gallery.xml";
$fp       = fopen($filename,"r+");
$old_data = fread($fp, 80000);
fclose($fp);



$input = "$post";
$old_data = str_replace('</gallery>', $old_data, "$input\n</gallery>");

$fp         = fopen( $filename,"w");
        if(!$fp) die("&error    =Failed to write!");
        fwrite($fp, $old_data, 800000);
        fclose( $fp );


}

You got the 2nd and 3rd parameters reversed, I think.

$old_data = str_replace('</gallery>', "$input\n</gallery>", $old_data);

You're quite right,

Thanks NogDog!
