Non-database 'CMS' written in PHP

[Spinethetic]

I've been toying with the idea of a sort-of-cms website that uses a single universal newsarticle.php page that is blank if you solely open that file; but has a php script (where you want the news article to appear) that retrieves a variable from the window.location.href passed on from the previous page



<?php
######################################
# This is where the problem is, somehow retrieving the number "23"
# from the address bar so that it knows which XML file to parse.
# I know that the below function is completely wrong though in regards
# to variable retrieval, but I'am still new to PHP :P
######################################
if (!$myxml=simplexml_load_file('window.location.href')){

echo 'Error reading the XML file';

}

foreach($myxml as $article){

echo '<h3> ' . $article->title . '</h3>';
echo '<a href=','' . $article->sourcelink . '','>' . $article->sourcelink . ' | ' . $article->date . '</a><br />';
echo '' . $article->story . '';

}

?>

ie:
http://mysite.com/index.php has a link that goes to
http://mysite.com/newsarticle.php?id=23

the variable being 23 in which the aforementioned PHP coded into newsarticle.php then parses and displays, say, 23.xml, which could be coded something like this:


<?xml version="1.0" encoding="utf-8" ?>
<index>
<article>
<title>Alien from mars speaks his/her mind at UN conference</title>
<source>BBC World News</source>
<date>12/25/08</date>
<sourcelink>http://bbc.co.uk/world/5674alien.aspx</sourcelink>
<story>blah blah blah blah</story>
</article>
</index>

Likewise if the variable had been http://mysite.com/newsarticle.php?id=24, then 24.xml would have been parsed instead.

Thoughts?

it seems like to many xml files, what if you had 100 stories? 100 xml files seems unreasonable.

PROBLEM SOLVED!

Man I'am really starting to love PHP! I don't know why I diden't switch before!



<?php
$variable = $_GET['id'];

if (!$myxml=simplexml_load_file(''.$variable.'.xml')){

echo 'Error reading the XML file';

}
### Rest of code irrelevant ###

mysite.com/view.php?id=abcdefg will load and parse abcdefg.xml, just as easily as mysite.com/view.php?id=h65h3456h56jkedj will load and parse h65h3456h56jkedj.xml, as long as the files exist anyway.

Just a tip.
You can change:


if (!$myxml=simplexml_load_file(''.$variable.'.xml')){

To this:


if (!$myxml=simplexml_load_file($variable.'.xml')){

I am new to php, so I must ask, what is the functional difference? I've gotten to chapter 5 in a book that I purchased and we havent really gotten tat far, (at least I think)

Its just cleaner.
When you start your code with a variable, lets call it $var, instead of:


echo ''.$var.' is the value of the variable.';

You might wanna just do this:


echo $var.' is the value of the variable.';

Then say, you wanna end with a variable, instead of doing this:

echo 'This is the value of the variable: '.$var;
But then say your using double quotes("). Then you don't even need to include the concatenation, and double quotes.
So, it'd be something like this:


echo "$var is the value of the variable";

Ahh, I see.

I still have a couple specific, but small problems with using this whole setup on my site. How do I return the article title itself to parse between <title></title> in the basic HTML; In the script I have ' . $article->title . ' which displays the article title from XML <title>The Last Question</title>. I really don't want a generic page title that is the same across every news article.

And I also have <subtitle>seconday title text</subtitle> that I will only be using on a few articles. There must be a way that I could go like so: <subtitle active="false"></subtitle> and the PHP will then ignore the line I have in bold so that I don't have an unnecessary line of whitespace:


<?php
$variable = $_GET['id'];

if (!$myxml=simplexml_load_file($variable.'.xml')){

echo 'Error reading the XML file';

}

foreach($myxml as $article){

echo '<h2> ' . $article->title . '<span></span></h2>';
echo '<b>' . $article->subtitle . '</b><br />';
echo '<a href=','' . $article->link . '','>' . $article->source . ' | ' . $article->publishdate . '</a><br />';
echo '' . $article->content . '';
echo '<p class=','meta','> <span class=','posted','>Posted by <a href=','mailto:admin@integralbuddha.net','>Ross Vaughn</a> on ' . $article->publishdate . '</span> <a href=','' . $article->permalink . '',' class=','permalink','>Permalink</a></p>';

}

?>

This is the link I'am testing the script on http://www.integralbuddha.net/n/v.htm?id=2

I didn't read your 2nd question, but I'm guessing that it also has to do with combining HTML and PHP like the first, so all you'd do is replace the:


<title>The Last Question</title>

With this:


<?php
echo "<title>The Last Question - $article->title</title>";
?>

Hmm, I should've been able to figure that one out on my own, I guess I was just getting caught up in the moment while I'am brooding over this technical scripting, (at least to me =P) and dident think.

Alright, glad to help you. :)
