Escaping preparsed variable content

Jamie Pittock 10 Apr 2013 15:29 question, complete

Is there any way to escape preparsed variables when their content contains the same quotes used to set the preparse parameter?

For example

preparse:dude="He goes by the name "Low""

I know I could change the outer double quotes to singles but I've no control over what may be entered in the future and it's very likely a single quote could be used at some point within the content.

   That's a tricky one. The parameters are just like any other. No simple, elegant way to escape quotes. But if the variable you're passing is a late parsed one, the issue shouldn't occur.

   So this is related to that query I emailed you about yesterday. I figured I'd stop bugging you and go the official route ;)
   
   

    
    {exp:safecracker} 
        {exp:low_variables:single 
            var="lv_form_field" 
            preparse:pp_instructions="{instructions:cf_organisations_email}" 
        } 
    {/exp:safecracker} 
    

   
   
   The {instructions:cf_organisations_email} is a Safecracker variable.
   
   I don't know whether that's an early or late parsed variable.
   
   My problem is that custom field instructions could possibly have double quotes in them.
   
   I guess I could wrap it in a plugin that converts " to ". Would that make it through?

   Yeah, using " instead of " would work. You could use Low Replace for that, but that could make things pretty verbose and obtuse.
   
   Also, you'd have to put the plugin inside the parameter, ie.
   
   

   preparse:my_var="{exp:quot}{my_variable}{/exp:quot}"

   
   
   ...which means you'd have to use parse="inward" as well.
