Just one more function

Hello,

Could anyone help me with the code below to create the php to output the html below.

function add_accesskeys($input) {

/*
// example data
$input = array(
	array('filename' => 'home.html',
		'title' => 'home page'),
	array('filename' => 'products.html',
		'title' => 'products'),
	array('filename' => 'contact.html',
		'title' => 'contact'),
	array('filename' => 'prices.html',
		'title' => 'prices'));

$output = <<<OUT

<ul>
<li><a href="home.html" accesskey="h">home page</a></li>
<li><a href="products.html" accesskey="p">products</a></li>
<li><a href="contact.html" accesskey="c">contact</a></li>
<li><a href="prices.html" accesskey="r">prices</a></li>
</ul>
OUT;
*/

return $output;

}

Try this on for size:

$input = array(
array('filename' => 'home.html',
'title' => 'home page'),
array('filename' => 'products.html',
'title' => 'products'),
array('filename' => 'contact.html',
'title' => 'contact'),
array('filename' => 'prices.html',
'title' => 'prices'));

print add_accesskeys($input);

function add_accesskeys($input) {
	$output = "<ul>";

if (is_array($input)) {
	$accessKeys = array();

	foreach ($input as $key => $out) {
		$file = $out['filename'];
		$title = $out['title'];

		if (count($accessKeys) > 0) {
			$i=0;
			while (in_array($accessKey, $accessKeys)) {
				$accessKey = strtolower(substr($title, $i, 1));
				$i++;
			}
		}else {
			$accessKey = strtolower(substr($title, 0, 1));
		}

		$accessKeys[] = $accessKey;
		$newTitle = ereg_replace($accessKey, "<em>". $accessKey . "</em>", $title);
		$output .= '<li><a href="'.$file.'" accesskey="'.$accessKey.'">'. $newTitle . '</a></li>';
	}

} 

return $output . "</ul>";
}

Won't that double up the accesskey? That is why I added that loop in there to check which access keys have been used. =)

Hi!
The accesskey and the key is the same value.

This line change both at once.:

$tmp = str_replace('%key', substr($elem['title'], 0, 1), $tmp);

Hi!
Sorry, but i dont se that it was possible to get the same accesskey in 'products' and 'prices'.
In that case frost110 is right. Sorry again, it`s late in Norway.. :o

No Problem. I did the same thing =) Great code though yours would of been way more efficient than mine =)
