Clarify A Doubt In Integrating Smart Contract To Front End

We built a smart contract for a pre-sale token, the front end was built using HTML, CSS, and PHP, now we want to call the function in the smart contract buy() from the front end

with an argument, the BUY button in the front-end first needs to get approval from the user end and then call the function buy in the smart contract,

this can be done by creating a function in a Java script file calling functions and changing the source of BUY SLN button in HTML.

this is the GitHub link of the file: [login to view URL]

Evner: CSS, JavaScript, PHP, HMLT5, Smart Contracts
