john, creating script snippits on the fly is generally not much use in an echo statement because echos just stream to the clients browser - nothing in that stream is actually ever going to be "executed"
The various solutions offered by other list members are particularly relevant to the creation of strings which will be written to a file. In other words echoing (to the browser) some html with a bit of PHP script buried in it (e.g. the form tags) will do just that - send to the browser something that it doesn`t understand, a browser can`t execute PHP script as it can say a piece of javascript. However, if you are writing a script which is intended to create yet another script for later use, these techniques work. An example of a script that creates a script... <?php // the name of this script is suicidal.php $somefilename = "hello.php"; $mystring = "<"."?"."php\n echo \"hello world\";\n"."?".">"; $fhandle = fopen ($somefilename, "w"); $writesuccess = fwrite ($fhandle, $mystring); fclose ($fhandle); ?> This will create a PHP script, a hello world script named hello.php. if we said (in the script) ... $somefilename = $PHP_SELF; then suicidal.php would overwrite itself and become a hello world script. (permissions issues aside - you may not be able to overwrite a file that is actually executing at the time). For your problem, needing to create a form in the clients browser with action=(the_same_script) you only need to so this .... assuming a script file name of ... add_to_cart.php echo "<form name=\"fred\" method=\"POST\" action=\"".$PHP_SELF."\">"; If the browser user clicked on "show source" he or she would see this... <form name="fred" method="POST" action="add_to_cart.php"> Is this what you want to do?? As Maxim said, you don`t really have to concatenate so pedantically but it helps demonstrate what is happening. cheers CD > ----- Original Message ----- > From: "John W.
