This is a sample of the code I wrote while working at Mantel for the project "Print product labels".
The php-html file is part of the raw code written in html using PHP as a scripting language, and the styling is applied to the components by using utility classes from Bootstrap as a css framework.
The javaScript.js file is the JavaScript code to apply the functionalities, by showing the warnings and disabling the button when a product without an url and a label with a QR is added to the list.
