I have a sourcerer tag in a joomla page that makes an AJAX call to retrieve some data from a database. My server side php program creates a text string from the data variables however they come back blank on the client side. If I call the php file outside of joomla I get the expected results. Don't know if this is a Sourcerer issue or if joomla is intervening somehow with the AJAX results?

I can return a pure text string just fine however any variables that I concatenate in the string disappear in joomla. Stuck.

For example:

$address is a variable that contains data from an SQL query.

When I return:

echo $address;

nothing comes back to the client (at least that I can see).

If I do:

echo "Hello" . $address;

I get Hello but no address. If I call this program outside of joomla I get Hello and the address.

Thanks for any advice.

Try including the file instead of placing the code within the article.
See here for more info on that:

I am using include not the code.

I mean, also do the other stuff in the external file. Like the
echo 'Hello '.$address;
