除非我检查元素，否则不会设置 Cookies

Question

So I am adding a cookie on a wordpress website in header.

setcookie("var", $var, time()+3600, "/", "website.com");

The problem is the cookie is visible and usable in php only if I inspect element -> application -> cookies (in browser). Otherwise I keep refreshing the page and going through the website with no cookie set. I know the cookie shouldn't be visible the first page load but even after the first load there is no cookie.

Not sure what's the problem at this point.

So I am setting the cookie on a subfolder /sub which is a wordpress file. And I am planning to use it on the index.php There's no issue there since after I inspect it and the cookie shows up everything works as expected.

Answer 1

If it shows up in your dev tools, the cookie was set - period.

You are actually just setting it, never querying it's value in your code. So how would you know if the cookie was set?

Just try var_dump($_COOKIE) - it should show the var cookie after you load the page a second time after the cookie has been set.
