Question

I have the following string in the smarty (php templating system) variable $test:

<img height='113' width='150' alt='Sunset' src='/test.jpg'/> 

I want to add ’em’ to the height and width like this:

{$test|replace:'' w':'em' w'|replace:'' a':'em' a'} 

But this doesn’t work… What’s the problem and the solution?

Answer 1

my regex isn’t the greatest, or i’d give you a better matcher, but maybe using what you have through the regex replace would work.

{$test|regex_replace:'/'.w/':'em' w'|regex_replace:'/'.a/':'em' a'} 

other matchers to try

'/\'.w/' '/'.*w/' '/\'.*w/' 

i can’t play with my smarty sites at the moment, but i’d first remove the ‘ from the replacement value, to see if the bug is there, then remove it from the matcher and just look for height/width.

otherwise i’d do the replace in PHP if you can.
