Only specific links on a specific page

[johnwinch42]

Hello,

 

I would like to know how to proceed to only have specific links to show on a specific page (index.php  for example)

The links would be in my footer and would only show up on my homepage.

 

How can I do that?

 

Thanks for your answers,

 

Best regards,

You want to use an IF statement with $_SERVER['php_self']

I'm kind of new to all of this, how can I implement this variable in my code?

Like this - 

<?php

	if( $_SERVER['PHP_SELF'] == '/index.php' )
	{
		print '<a href="page2.php">Go to page 2</a>';	
	}
	elseif( $_SERVER['PHP_SELF'] == '/page2.php' )
	{
		print '<a href="index.php">Go Home</a>';	
	}

?>

Thanks you very much!

 

For the else I don't want to show anything on the other pages, would it be something like this?

 

<?php

    if( $_SERVER['PHP_SELF'] == '/index.php' )
    {
        print '<a href="page2.php">Go to page 2</a>';    
    }
    else
    {
        print ' ';    
    }

If you don't want anything to show up, you don't need the else. The links will only show up when the if conditions are met.

 

Also note that you could use a switch for multiple pages:

 

<?php
switch($_SERVER['PHP_SELF']) {
     case '/index.php':
          print '<a href="page2.php">Go to page 2</a>';
          break;
     case '/page2.php':
          print '<a href="index.php">Go Home</a>';
          break;
}
?>

Great it's working thanks you

 

But is there a way to put the full url instead of the path in   if( $_SERVER['PHP_SELF'] == '/index.php' ) ?

You could try using $_ENV['SCRIPT_URI']

[johnwinch42]

Like this? 

<?php

    if( $_ENV['SCRIPT_URI'] == 'http://www.test.com' )
    {
        print '<a href="page2.php">Go to page 2</a>';    
    }
    else
    {
        print ' ';    
    }

?>

You'll need to use the full URL.

 

<?php
if($_ENV['SCRIPT_URI'] == 'http://www.test.com/index.php' ) {
     print '<a href="page2.php">Go to page 2</a>';
}
?>
