Post Submission Trouble With Theme

I'm having trouble adding a post_submission to my functions.php in my theme. I thought it might be a conflict with the theme itself, but I've switched to a simple theme and am encountering a similar problem.

I've created a single Gravity Form and when I add this to my functions.php:

add_action("gform_post_submission_1", "set_post_content", 10, 2);
function set_post_content($entry, $form){
//do nothing
}

I get an error. I've tried moving it around in the functions.php file to no avail. Is there a full example of a functions.php file that I can examine?

I'm using WP version 3.2.1 and GF 1.5.2.8.

Thanks,

Brent

One thing to note: Not sure it is related but part of my WP site uses Exec PHP. As part of my troubleshooting I had disabled it. Problem still existed and then I re-enabled it and my code started working.

I don't think that is the issue. When I try to use any of the $entry values in my code, I get an error. I've tried to simplify it but it looks like when I reference the $entry, it blows out.

At the moment I'm just trying to insert either the user $entry['created_by'] and/or a hidden form value $entry['1'] which would return the user name. Both of these values are to go into my custom table.

Any thoughts?

In my functions.php, this code executes successfully (I've hidden my database info):

add_action("gform_post_submission_1", "set_post_content", 10, 2);
function set_post_content($entry, $form){
	define("HOSTNAME","*****");
	define("USERNAME","*****");
	define("PASSWORD","*****");
	define("DATABASE","*****");
	$con = mysql_connect(HOSTNAME, USERNAME, PASSWORD);
		if (!$con)
		{
			die('Could not connect: ' . mysql_error());
		}
		echo "do";
		$sql="INSERT INTO user_items (user, item) VALUES ('1', '2')";
		if (!mysql_query($sql,$con))
		{
			die('Error: ' . mysql_error());
		}
		mysql_close($con);}

The form executes, my data gets entered, and my "do" is written to the form as expected. If I change the code to this:

add_action("gform_post_submission_1", "set_post_content", 10, 2);
function set_post_content($entry, $form){
	define("HOSTNAME","*****");
	define("USERNAME","*****");
	define("PASSWORD","*****");
	define("DATABASE","*****");
	$con = mysql_connect(HOSTNAME, USERNAME, PASSWORD);
		if (!$con)
		{
			die('Could not connect: ' . mysql_error());
		}
		echo "do";
		$sql="INSERT INTO user_items (user, item) VALUES ($entry['created_by'], $entry['2'])";
		if (!mysql_query($sql,$con))
		{
			die('Error: ' . mysql_error());
		}
		mysql_close($con);}

I get this error or a variation of it:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/content/63/6744963/html/wp-content/themes/CeCe3/functions.php on line 38

The line number of the error generaly doesn't point to anything meaningful.

Let me know if you need more info.

Thanks. That got me the rest of the way. Hats off for auto-incrementing the file upload name if it already existed. I was going to write something to handle that.
