do things with the return value of smarty function?
javascript, php, smarty
Solution
Use `escape` modifier, for example:
{$variable|escape:'quotes'}
For smarty function, you can first try if `{smarty_function|escape:'quotes'}` works, if it doesn't then you have to assign the output of the function into a variable first before escaping it, and for that you use `capture`:
{capture name=mycapture}{smarty_function}{/capture}
{$smarty.capture.mycapture|escape:'quotes'}
Problem
We have this Smarty function that returns HTML code for templates. However it is also possible that the function returns a null string, which we now wish to identify. Our system has been running stably for years, so I am looking for the least invasive possible solution. Is it possible to assign the return value to a smarty variable? I have tried assigning it to a Javascript variable, however, because part of the HTML is user generated, the return string could be a mixture of double and single quotes, which causes problems in IE (unfortunately the majority of our user base). ``` <script type="text/javascript"> var html = '{smarty function}'; //IE chokes on mixed quotes </script> ``` Any help appreciated!
