Square Payment Module for Zen Cart [Support Thread]

[todoonada]

I asked Square about it, and they said:


So I guess that means needing to write some custom javascript, which you'd fire from jscript_square.php before the paymentform js is loaded.

Thank you.
I tried that changing jscript_square.php. First I made a little test. I changed the line
console.error("Encountered errors:");
to
console.error("Test");

My changed line shows up in the source code of the page, but the console still shows "Encountered errors:" instead of "Test".
