HELP PLEASE - Echo Values of Multi-Dimensional Array Based on ID

[theluckyy1]

I have 1 array with 2 dimensions which is hard coded on my page.

THIS CODE WOULD BE ON REDIRECT.PHP

$aff = array(0=>array('title'='A Website Title','afurl'='http://www.external-affiliate-site.html?affiliateid=1234'),1=>array('title'='Another Website Title','afurl'='http://www.external-site-training-your-pitbull-made-easy.html?affiliateid=1234')); 

I have a link on my website which when it is clicked goes to redirect.php. I need to get both Values from my Array which match up with an ID that is passed to my page via PHP GET.

http://www.link-on-my-site.com/redirect.php?myid=0

Once the variable "myid" is passed to redirect.php, I will capture it on redirect.php.

$affiliate = $_GET['site']; 

This is where I get stuck.
From here I need to get both values "afurl" and "title" from the array and set each one of the values to an individual variable so I can print them.

PLEASE PLEASE HELP....

Uhm,

$id=(int)$_GET['myid'];
 
$site=$aff[$id]['title'];
$url=$aff[$id]['afurl'];

Take it easy genius - some of us might be newbies...

But thanks.

I shall test this out.

<pre>
<?php
$aff = array(0 => array('title' => 'A Website Title', 'afurl' => 'http://www.external-affiliate-site.html?affiliateid=1234'), 
1 => array('title' => 'Another Website Title', 'afurl' => 'http://www.external-site-training-your-pitbull-made-easy.html?affiliateid=1234'));

print_r($aff);

$id=(int)$_GET['myid'];
 
$site=$aff[$id]['title'];
$url=$aff[$id]['afurl'];

?>
<a href="<?php echo $url ?>"><?php echo $site ?></a>

Array
(
    [0] => Array
        (
            [title] => A Website Title
            [afurl] => http://www.external-affiliate-site.html?affiliateid=1234
        )

    [1] => Array
        (
            [title] => Another Website Title
            [afurl] => http://www.external-site-training-your-pitbull-made-easy.html?affiliateid=1234
        )

Actually, we should carry it a bit further, to make things nice and clean:

$id=(int)$_GET['myid'];
 
if(array_key_exists($id,$aff)){
  $site=$aff[$id]['title'];
  $url=$aff[$id]['afurl'];
}else{
  echo 'Affiliate not found!';
}

OK I know this is USER ERROR on my part... but i think i have a syntax error in my ARRAY..

<?php

$id=(int)$_GET['myid']; 

$aff = array(0=>array('title'='A Website Title','afurl'=>'http://www.someaffiliate9.html?affiliateid=1234'),1=>array('title'='Another Website Title','afurl'=>'http://www.training-your-pitbull-made-easy.html?affiliateid=1234'));

$site=$aff[$id]['title'];
$url=$aff[$id]['afurl'];

echo $site 

echo $url

?>

I get the following error when i test this page.

Parse error: syntax error, unexpected '=', expecting ')' in /home/7252/domains/hoosiermate.com/html/index.php on line 5

MANY THANKS to Ernie1 and php_daemon for your help with this BIG problem for my NEWBIE self.

You guys are Awesome!!

Thanks again!

Ready for part 2

Here is the situation...at some point the array is going to get large. And hard to read on the page.

Part 1: Can the array be formatted in my php with line breaks or something to help it read better?

Part 2: This array has the potential to be very large. At what point should I begin to worry about performance on this page with the size of my array?

Thanks again!

[php_daemon]

1) Yes

2) You should start worrying now. Consider using database.

[theluckyy1]

1) can you provide an example?

2) that is what i was afraid of :-(

[php_daemon]

1)

$aff = array(
0 => array( 'title' => 'A Website Title', 
            'afurl' => 'http://www.external-affiliate-site.html?affiliateid=1234' 
           ), 
 
1 => array( 'title' => 'Another Website Title', 
            'afurl' => 'http://www.external-site-training-your-pitbull-made-easy.html?affiliateid=1234'
           )
);

2) It's not that hard as may seem. And worth learning anytime. You can start at http://www.php.net/mysql and/or look up SitePoint's articles.

Thanks again.

i am reading up now. I am sure I will have questions
