Arrays in Navigation

[Uluen]

I have searched here, googled, read about List(), Each() but I'm still stomped.

Here I assign values to a list of links:

$cfg['siteLink']['index']['to the front page']	= 'index.php';
$cfg['siteLink']['music']['to the music database']	= 'music.php';

Trying to extract back out from array:

function siteLinks() {
	global $cfg;
	while (list($linkDescr, $linkName, $linkFile) = each($cfg['siteLink'])) {
		echo ' | <a href="' . $linkFile . '" title="' . $linkDescr . '">' . $linkName . '</a>';
	}
}

I have struggled with this for hours now but I can't get the A HREF part to work like I want it to.

print_r ($cfg['siteLink']);

Prints: Array ( [index] => Array ( [front page] => index.php ) [music] => Array ( [music database] => music.php ) )
It looks like populating(is it populating? 🙂 the array works ok?
Do I need another WHILE() because it is 3 values? One of my PHP-books say something about 4 values?

Any suggestions? Maybe this is a stupid way to build list of links?
It worked ok before I decided to add a third value to the array ($linkDescr - hover text on links) except my link divider (the "|") was after the last link too, guess thats my next goal 🙂

I have been lurking here a long time and I must say you people are the best, keep up the good work!

The list function can be used like this:

<?php

$data = array( "monkey" , "bear" , "cat" , "dog" );
while( list( $key , $animal ) = each( $data ) )
{
     echo $animal . "<br/>\n";
}

?>

I don't think that you can use the [man]list()[/man] function the way that you're trying to..

It works if I have

$cfg['siteLink']['index']	= 'index.php';

And

echo ' | <a href="' . $linkFile . '">' . $linkName . '</a>';

The fact that

print_r ($cfg['siteLink']);

returns what I expects makes me think I got some part of my code wrong, just cannot figure out what 🙂

Thanks again.

I know what it is. If you have an array like this one:

g['siteLink']['index'] = 'index.php';

and then run through it with list() then you will get the correct stuff:

$linkFile = index.php
$linkName = index

but if you have an array like this one:

$cfg['siteLink']['index']['to the front page'] = 'index.php';

then the values you get will be different:

$linkName = index
$linkFile = Array

This is because the content in $cfg['siteLink']['index'] is an array. What you've got to do is this:

$cfg['siteLink']['index']['to the front page']    = 'index.php'; 
$cfg['siteLink']['music']['to the music database']    = 'music.php';

while( list( $linkName , $linkData ) = each( $cfg['siteLink'] ) )
{
	while( list( $linkDescr , $linkFile ) = each( $linkData ) )
	{
		echo ' | <a href="' . $linkFile . '" title="' . $linkDescr . '">' . $linkName . '</a>';
	}
}

Perfect, that works!
