gracer

Been looking for this solution for years.

Please let us know

I crash my site everytime too

function add_parameter_to_url($content) {
	$transaction_id="";
	if(!empty($_GET['transaction_id'])) $transaction_id=$_GET['transaction_id'];

	$aff_sub="";
	if(!empty($_GET['aff_sub'])) $aff_sub=$_GET['aff_sub'];

	$aff_sub2="";
	if(!empty($_GET['aff_sub2'])) $aff_sub2=$_GET['aff_sub2'];

	$source="";
	if(!empty($_GET['source'])) $source=$_GET['source'];

	$affiliate_id="";
	if(!empty($_GET['affiliate_id'])) $source=$_GET['affiliate_id'];

	$content=str_replace('{transaction_id}',$transaction_id,$content);
	$content=str_replace('{aff_sub}',$aff_sub,$content);
	$content=str_replace('{aff_sub2}',$aff_sub2,$content);
	$content=str_replace('{source}',$source,$content);
$content=str_replace('{affiliate_id}',$affiliate_id,$content);
	//$content="testing";
	return $content;
}

add_filter( 'the_content', 'add_parameter_to_url',20 );

`

Did you get this to work??

Thank you, anyone you recommend?
