I am working on a React eCommerce website and I am having difficulties in showing the pdp complete with all the fields I need (title(ok), price(NO), description(NO), image(NO)). The process should be that whenever a user clicks on a <Picture Card /> component, then it should open up the pdp of that product. Right now, if this happens I managed to show in the page the title trough React Routes, and I can log out all the fields I need correctly, but I cannot make it appear on the pdp page (I dont know how to pass the data here).
I was thinking to lift up the state to my Parent component (<App /> ) and then pass it to my <Pdp /> component as props. But how can I do this exactly ?
Right now I get the folowing error when I click on a <Picture Card /> component: "TypeError: this.props.parentCallback is not a function"
What am I missing ? Thanks in advance!
