Problem with PHP with external XML content

I am having issue on my PHP photo gallery. The album name is generate by the folder name as below:

 

'. $_GET['album'

 

So what I am trying to do is to show some external xml date in the gallery base on different albums name, I now tested with 3 different albums with the folder name Adriana, Alicia and Eva. Once again the album name is generate by the folder name.

 

$folder_name = $_GET['album'];

echo $folder_name;

 

The above code is working to get the title on specific folder name of that album.

 

Next I have a external xml file with different info for each album. Which I would like to show different info for each album. my xml file as below:

 

 

<?xml version="1.0" encoding="UTF-8"?>

<library>

<models>

<Adriana>This is the model info of Adriana</Adriana>

<Alicia>This is the model info of Alicia</Alicia>

<Eva>This is the model info of Eva</Eva>

</models>

</library>

 

I first tested with this code to make sure it can read the "info":

 

 

<?php

$url = 'albums/Adriana/info.xml';

$xml = simplexml_load_file($url);

 

$info=$xml->models->Adriana;

 

echo $info;

?>

 

Above code works fine, but what I really need to do is something like this, and this is the part that I got an error.

 

$info=$xml->models->$folder_name;

 

Please let me know what am i missing on the above line.

What error did you get?

It works for me

 

<?php
$str = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<library>
<models>
<Adriana>This is the model info of Adriana</Adriana>
<Alicia>This is the model info of Alicia</Alicia>
<Eva>This is the model info of  Eva</Eva>
</models>
</library>
XML;

$xml = simplexml_load_string($str);
$folder_name = $_GET['album'];
$info = $xml->models->$folder_name;
echo $info;  //--> This is the model info of Alicia
?>

I see the issue now, because some of my folder name is as follow:

 

 

<John Doh>This is the model info of Alicia</John Doh>

 

 

With a space after the first name:

 

and i got an error say : parser error : Specification mandate value for attribute Doh

 

are there anyway to make that work if there will be space in my folder name?

Yes, just when I attempt to add a space in a tag as bellow:

 

 

<?xml version="1.0" encoding="UTF-8"?>

<library>

<women_fashion>

<Adriana>height 5'10, bust 34, waist 24, hips 35, dress 10, hair brown, eyes green.</Adriana>

<Eva>This is the model info of Eva</Eva>

<John Doh>This is the model info of John Doh</John Doh>

</women_fashion>

</library>

 

and I got this error log:

Warning: simplexml_load_file() [function.simplexml-load-file]: info.xml:6: parser error : Specification mandate value for attribute Doh in C:\xampp\htdocs\Iconmodels.ca\women_fashion.php on line18

 

Warning: simplexml_load_file() [function.simplexml-load-file]: <John Doh>This is the model info of John Doh</John Doh> in C:\xampp\htdocs\Iconmodels.ca\women_fashion.php on line 18

 

Warning: simplexml_load_file() [function.simplexml-load-file]: ^ in C:\xampp\htdocs\Iconmodels.ca\women_fashion.php on line 18

 

Warning: simplexml_load_file() [function.simplexml-load-file]: info.xml:6: parser error : expected '>' in C:\xampp\htdocs\Iconmodels.ca\women_fashion.php on line 18

 

Warning: simplexml_load_file() [function.simplexml-load-file]: <John Doh>This is the model info of John Doh</John Doh> in C:\xampp\htdocs\Iconmodels.ca\women_fashion.php on line 18

 

Warning: simplexml_load_file() [function.simplexml-load-file]: ^ in C:\xampp\htdocs\Iconmodels.ca\women_fashion.php on line 18

 

And so far I will need a space in between the tag, because I am using the folder name as the album person name. Are there anyway to do a tag with a space?

XML element names don't have spaces. When you use something like <John Doh> it is the start tag of a John element with an empty Doh attribute.

 

The errors that you are seeing are because </John Doe> is not valid XML (it expects only the element name there).

 

It would probably make more sense to have a structure that does not rely on the model name being a valid XML element name, perhaps <model name="John Doh">…</model> then you can search the <model> elements by their name attribute.  XPath makes this easy, and we can help you with that if you need it.

I am not very experience with PHP MYsql database, my website is not run on a database. but I try to make the updating part as simple as I can, by ftp a folder with images and the album name will be the folder name. and you are right this is why things getting so messed up. Maybe I should learn how to create a data base gallery.

Better ways to construct your XML would be

 

<?xml version="1.0" encoding="utf-8"?>
<models>
   <model name="Alicia">
    <info>This is info about Alicia</info>
   </model>
  <model name="John Doe">
    <info>This is info about John Doe</info>
   </model>
</models>

 

or

 

<?xml version="1.0" encoding="utf-8"?>
<models>
   <model>
    <name>Alicia</name>
    <info>This is info about Alicia</info>
   </model>
   <model>
    <name>John Doe</name>
    <info>This is info about John Doe</info>
   </model>
</models>

 <info>This is info about Alicia</info>
</model>
<model>
 <name>John Doe</name>
 <info>This is info about John Doe</info>
</model>
</models>

 

One last question, in order to print the info of John Doh, I get nothing with the code below:

echo $xml->model->name("John Doh")->info;

I think i did somthing wrong there.
