Basic PHP $_GET help + Basic Navigation.

[RuSty]

Ok, so I am re-learning php and I am having some trouble using $_GET variables.

 

I want to use it for two things:

1. dynamic content - ie when a user clicks of "services" the url will be www.sitename.com/index.php?page=services

2. dynamic styles - so when a user clicks on a provided "color box" the website will reskin itself accordingly.

 

so in otherwords a desired url could be:

www.sitename.com/index.php?page=services&style=blue

 

How I have it setup right now is by having the navigation menu buttons just link like this < a href="index.php?page=services"></a>

 

and then i tried setting up the styles like this:

 

<a href="<?php $url . "&style=blue" ?>"></a>

and it worked fine except an obvious problem, if you clicked the button twice the url would read:

www.sitename.com/index.php?page=services&style=blue&style=blue

 

 

So does anyone know a more effecient way of doing this?

 

 

 

Thank you,

Um, use the file name instead of just adding on.

 

So instead of:

 

&style=blue

 

Use:

 

index.php?page=services&style=blue

but with a URL such as:

 

index.php?page=services&style=blue

 

is there any way to change $_GET['page'] but not $_GET['style']

 

So if a user clicks on contact,

the 'style' wont change but the 'page' will?

[marcus]

You could try this:

 

<?php
$page = $_GET['page'];
$style = $_GET['style'];
$pages = array('your','page','names');

foreach($pages AS $links){
if($page){
	if($links == $page){
	$url = "$links<br>\n";
	}else {
	$url = "<a href=\"index.php?page=$link&style=$style\">$links</a><br>\n";
	}
}else {
$url = "<a href=\"index.php?page=$link&style=$style\">$links</a><br>\n";
}
echo $url;
}
?>

 

*TESTED* works fine.
