Stop print_r from printing 1's

[wmdvanzyl]

I was wondering whether there is a way to stop the print_r function from printing 1's all over the place. I assume it is the "true" value it returns after completing successfully. I was wondering if there is a way around this or perhaps there is a better way to debug stuff when you need screen output than print_r?

Any suggestions?

Re the '1' this can happen for a coupla reasons, say a function returning true, or if you do it against an array (i think) it can mean that the array is set, but has no values

Have you tried {debug} or {get_template_vars} ...? Think both of these are documented in the tags section of the cms

Or use it in html comment, so your visitors don't see it while you're debugging (unless they look in source).

End you don't need the <pre> tags

<!-- {$var|print_r} -->

Thanks for the feedback.

I do use those, but there are times you just need to print_r something to the screen. Where i got confused was when the output of print_r was actually 1, but i couldn't see it amongst all the 'other' 1's

<!-- {$var|print_r} -->

That's smart, but in this case it wasn't the output to end users that needed to be altered, but rather the output i get. If, for example, i output a variable which has a value of 1, i tend to miss it and think that it is blank, because there are so many 1's floating around.

Try:

Code: Select all

{$var|print_r:true}
