Hello,

 

I am slowly learning how to do more and more with php and integrating it into my sites.

The latest thing I have come up with is to swap the logo on a site depending upon the time of year.

5 logos: a default and then one for Christmas, Easter, valentine and Halloween.

 

It seems to work but I am sure there is a way to make this better. It currently inserts the link into an <img src""/> but all the php is included within the src"" which seems a little untidy! Would I be better to remove this to an external file and have it insert only the relevant link? I am concerned about not only the page looking untidy but also the SEO implications of having all this code at the top of my site.

 

thanks

 

	<?php 	$today = date('Y-m-d');
				$xmasOn = '2010-12-01';
				$xmasOff = '2011-01-06';
				$valentineOn = '2011-02-07';
				$valentineOff = '2011-02-21';
				$easterOn = '2011-04-17'; //easter sunday - April 24
				$easterOff = '2011-05-01';
				$halloweenOn = '2011-10-24';
				$halloweenOff = '2011-11-06';

			if ( ( $today >= $xmasOn ) && ( $today <= $xmasOff ) )
				{echo "images/winking_logo_xmas.gif";}
			elseif ( ( $today >= $valentineOn ) && ( $today <= $valentineOff ) )
				{echo "images/winking_logo_valentine.gif";}
			elseif ( ( $today >= $easterOn ) && ( $today <= $easterOff ) )
				{echo "images/winking_logo_easter.gif";}
			elseif ( ( $today >= $halloweenOn ) && ( $today <= $halloweenOff ) )
				{echo "images/winking_logo_halloween.gif";}
			else {echo "images/winking_logo.gif";}	
	?>

If you want it to look neater in your IDE/editor then store the code in an include file and call that.

 

<img src="<?php include ('dynamic_logo.php');?>" />

 

or store it all at the top of the page and get it to populate a variable instead of echoing the data.

 

<img src="<?=$dynamicLogo?>" />

 

 

Either way there are no SEO implications as your web server will parse the PHP and only output the image string.

Ah OK I didn't realise that was the case with SEO implications. The file is already actually a php include file so I might as well leave it where it is!

 

Thanks for the hints.
