Smarty/PHP errors
Smarty can catch many errors such as missing tag attributes
or malformed variable names. If this happens, you will see an error
similar to the following:
Example 17-1. Smarty errors Warning: Smarty: [in index.tpl line 4]: syntax error: unknown tag - '%blah'
in /path/to/smarty/Smarty.class.php on line 1041
Fatal error: Smarty: [in index.tpl line 28]: syntax error: missing section name
in /path/to/smarty/Smarty.class.php on line 1041 |
|
Smarty shows you the template name, the line number and the error.
After that, the error consists of the actual line number in the Smarty
class that the error occured.
There are certain errors that Smarty cannot catch, such as missing
close tags. These types of errors usually end up in PHP compile-time
parsing errors.
Example 17-2. PHP parsing errors Parse error: parse error in /path/to/smarty/templates_c/index.tpl.php on line 75 |
|
When you encounter a PHP parsing error, the error line number will
correspond to the compiled PHP script, not the template itself. Usually
you can look at the template and spot the syntax error. Here are some
common things to look for: missing close tags for
{if}{/if} or
{section}{/section},
or syntax of logic within an {if} tag. If you
can't find the error, you might have to open the compiled PHP file and
go to the line number to figure out where the corresponding error is in
the template.
Example 17-3. Other common errors Warning: Smarty error: unable to read resource: "index.tpl" in...
or
Warning: Smarty error: unable to read resource: "site.conf" in... |
