Re: [PHP] Viewing a specific item within a php web-page?

2005-04-10 Thread Prathaban Mookiah
I guess I had some 'spelling mistakes' in my suggested code.

Try the one below. It should be $HTTP_GET_VARS not $_HTTP_GET_VARS.



And you can name the script in any way you want to. It need not be script.php. 
Say if you put this code into a script call getarticle.php, you should call it 
as youdomain/getarticle.php?articleid=post_x where  is the appropriate 
article number.

As someone else suggested, putting them into a database is the best way to do 
it. But since I guess you are a beginner you might as well keep it very simple 
like this for the time being. But ultimately you should consider databases.

Cheers,

Prathap

I have a document entitled: articles.php
Within this document, I want to store various written articles which are headed by a 
string value - example:

$post_040905 = "text for April 9th 2005";
print($post_040905);
$post_041005 = "article for April 10th 2005";
print($post_041005);
That's a _really_ bad idea. It is better to store all of them in a 
database (MySQL is a simple one and works perfectly with PHP) ordered by 
an id. So the script can take a numerical argument ID which will hold 
the ID of the text which shall be shown. The argument can be passed as a 
GET variable (script.php?variable=value&second=second_value) and you can 
get it with $_GET['variable_name']. Take a better look here 
http://www.php.net/manual/en/reserved.variables.php#reserved.variables.get 
. However don't forget to filter than input argument first, to prevent 
SQL Injections :

$id = $_GET['id'];
if($id == strval(intval($id))) { /* Okay, do the query */ }
else die('Looser !');
Hope this helps,

I think you have totally got it wrong. You pass on the value to a php script 
in the form on http://   /script.php?variable=value.

So to accomplish your need you may have to do something like call http://   
/script.php?articleid=post_040905.

Your program should be modified to maybe something like:



There are more efficient ways to do it, but this should get the job done.
