[PHP] setting the same value to multiple variables
Hi,
I'm sure this is quite basic. Nonetheless I'm new to PHP so I haven't
figured it out.
I'd like to set each variable to the same value (without having to
set that value individually for each variable).
Thanks for the help.
best,
Charles

$goodToGo = 0; $errorArray[] = You must declare some goals on
Activity 1.;

$readingGoalsCommunicateLabelClass = class=\errorHere\;

While this seems like excessively ugly code (have you considered an
array? what is the point of all those variables if they all hold the
same value?), replace all of those '' with '=' and you will be fine.
PHP evaluates right-to-left and the result of an assignment is the value
that was assigned, so that will work.

Just cutting out the long IF statement so everyone didn't have to
look past it.

Ah, I see. Thanks.
I place the variable in the label tag for each of the corresponding
inputs (checkboxes in this case). If none are checked (at least one
is required) I set an error message at the top of the page and then
set a background color on each label via the now present
class=errorHere.
I'm sure there's a better way to do this, but I'm not the best with
PHP. I'll look into using an array.
Thanks again for your help. You've shortened my code at least a
little bit.
best,
Charles
