php - Smarty: cannot replace string

742

I'm new to Smarty and I have a variable which contains a URL http://someurl.com and I'm trying to perform a replace operation on it, to show http://m.someurl.com. This is what I have, but it's not working.

{$theurl | replace: 'http://' :'http://m.'}

I also tried assigning the $theurl to a second variable and perform the replacement there, but I have no luck.

I also tried escaping the slashes, replacing http for xxx, and nothing works.

I took a look here for reference: http://www.smarty.net/docsv2/en/language.modifier.replace.tpl

Solution:

Can you give us some more information on the variable itself? How about you use a var_dump to show the current value of the variable:

{$theurl|var_dump}

Why are you using spaces in the smarty syntax, maby that is the problem:

{$theurl|replace:'http://':'http://m.'}
