I am working with Magento. all I want just a button that add a product to cart and then go to check out page not to view cart. means I want direct order for the registered users. and I am working in PORTO Magento theme I have tried it by creating copy of function addAction of cartController.php(app/code/core/checkout/controllers/) to myaddAction().
added below JS to end view.phtml(app/design/frontend/your package/your template/template/catalog/product/view.phtml)
productAddToCartForm.submitmy = function(button, url){
replaceURL = url.replace("add/","myadd/");
if(this.validator) {
var nv = Validation.methods;
delete Validation.methods['required-entry'];
delete Validation.methods['validate-one-required'];
delete Validation.methods['validate-one-required-by-name'];
// Remove custom datetime validators
for (var methodName in Validation.methods) {
if (methodName.match(/^validate-datetime-.*/i)) {
delete Validation.methods[methodName];
}
}
if (this.validator.validate()) {
if (url) {
this.form.action = replaceURL;
}
this.form.submit();
}
Object.extend(Validation.methods, nv);
}
}.bind(productAddToCartForm);

$this->_goBack();
to
$this->_redirect('checkout/onepage');
return;
