View Full Version : eval() troubles.

I've been trying to create a template system, and ran into a problem that seems like it'd be a simple fix, but I can't seem to find the answer. I'm low on time, so I'll just you the code I have and the error rather than explaining it.

Get Template Function (works):
function fetch_template($name)
{
$get_template = "SELECT `template` FROM `templates` WHERE `name`='$name' LIMIT 1";
$get_template_res = mysql_query($get_template);
$fetch_template = mysql_fetch_array($get_template_res);
$template = $fetch_template['template'];

return $template;
}

Eval Function and Echo Output:
eval('$display = "' . fetch_template('template_name') . '";');
echo $display."\n";

PHP Error:
Parse error: syntax error, unexpected '<' in path/to/php/file(24) : eval()'d code on line 3


I'm pretty sure it's a problem with the eval function reading HTML from the template. Just can't figure out a fix.


Thanks in advance

the evaled code has a syntax error on line 24.
that's it :)

From your post it sounds like what gets returned from your fetch_template() function is HTML code. Well of course that's not going to work-- the eval() function requires PHP code. So unless the string is "print '<html blah blah>'" and there's just errors in fetch_template() (which you say there isn't), you'll need to figure out another way.

It IS PHP. There is HTML in it, but it's in PHP format. The point is, no matter what it's evaluating, it still returns errors. I even limited down to extracting only this from the template:

$str = \"test\";
echo $str;

and what it returns is this:

Sorry if I sound a bit frustrated. I've spent years and countless hours trying to understand the eval function, but I've never gotten anywhere.

If you are making an eval(); you cant forget you have to put backslashes before a variable you want to set:


eval("\$display='...';");
