Calling a Variable with a Variable?

I'm not sure if I'm even asking this question right:

The website I'm updating is written in PHP an Smarty and since I wouldn't consider myself a programmer in either I'm running into a bit of trouble.

What I'm trying to do is call an rss feed based on the page title. I was able to get the page title to show up on the tpl page within {php} but I can't seem to set it as a variable. Here's what I'm trying:

$rss_keyword = echo $this->_tpl_vars['title']

Code (markup):

What am I missing?

 

You can use eval() to execute a string as php.

However, I am not sure I quite understand what you're trying to do by your description.

 

Thanks SeLfkiLL I'm not really sure I understand what your saying either

Say the title of the page is Chocolate and

echo $this->_tpl_vars['title']

Code (markup):

figures that out based on the page title.

In this case I want to Chocolate to be the $rss_keyword

So

$rss_keyword = 'Chocolate' 

Code (markup):

Does that help at all

 

You might try:

$rss_keyword = $this->_tpl_vars['title'];

Code (markup):

The way you have written the code will generate a parse error because you cannot have something equal to the result of an "echo" statement. PHP will complain that it has encountered an "unexpected T_ECHO"

 

$this->_tpl_vars["rss_keyword"] = $rss_keyword;
echo $this->_tpl_vars["rss_keyword"]

PHP:

I think you want that ..... then you'll have the rss keyword inplace of the title, and take notice of post above.

 

krakjoe -

How would the site know what the title of the page is to use as the rss_keyword with your example? I think I'm missing something.

 

Your answer works when I test it with something simple like

echo $rss_keyword

Code (markup):

I just didn't realize it because the RSS Reader I'm using, CARP, is throwing an error. Thanks for everyone's help I may just not be able to pull stories on the fly with carp.
