I want to see if the cookie still is ther, if it's not ther enymore ther then it has to make a cookie, else it must use the old one that has been made earlier.
My problem is, how can I see if the Cookie still ther or not?
What do I have to use, isset or empty or what ever?
I want to do this with php.
if Cookie is ther then use it, else go to main page to re enter the user name en make a new cookie.
Who can help me with this?
Cookie problem, cookie doesn't want to be used again.

If your cookie is called 'mycookie' then to check if it is set you would do something like:
Mac
Code: Select all
if (isset($_COOKIEї'mycookie'])) {
// cookie is set
} else {
// cookie not set
}

I now have this, but it doesn't make a cookie when ther is no cookie? what is wrong?
Code: Select all
<?php
$NewNaam=$_POSTї"NewNaam"];
if (isset($_COOKIEї'Naam'])) {
$Naam = "$NewNaam";
} else {
$NewNaam=$_POSTї"NewNaam"];
setcookie("Naam",$NewNaam,time()+40000,"/test/");
$Naam = "$NewNaam";
}

Try this and refresh the page each time because (setcookie() info):
If you want to delete the cookie again just uncomment the
line.
Mac
php manual wrote:Cookies will not become visible until the next loading of a page that the cookie should be visible for. To test if a cookie was successfully set, check for the cookie on a next loading page before the cookie expires. Expire time is set via the expire parameter.
Code: Select all
<?php
$NewNaam = $_POSTї'NewNaam'];
//setcookie('Naam', '', time()-1000);
if (isset($_COOKIEї'Naam'])) {
$Naam = $NewNaam;
echo 'cookie exists';
} else {
$cookieset = setcookie('Naam', $NewNaam, time()+40000);
if (!empty($cookieset)) {
$Naam = $NewNaam;
echo 'new cookie set';
} else {
echo 'error - cookie could not be set';
}
}
?>Code: Select all
//setcookie('Naam', '', time()-1000);Mac
The problem now is, the cookie is made, it is still ther, but when you are plasing an order and you want to go back to the order list, It only shows that the cookie exists and doesn't show the name enymore, wher it should be shown. The name must be shown again, after a second visit.
Her is my compleet sorce code.
<?php
$NewNaam = $_POST['NewNaam'];
//setcookie('Naam', '', time()-1000);
if (isset($_COOKIE['Naam'])) {
$Naam = $NewNaam;
echo 'cookie exists' ;
} else {
$cookieset = setcookie('Naam', $NewNaam, time()+40000);
if (!empty($cookieset)) {
$Naam = $NewNaam;
echo 'new cookie set';
} else {
echo 'error - cookie could not be set';
}
}
// Hier wordt Cookie gemaakt als hij nog niet bestaant

Okay,
Your line $NewNaam = $_POST['NewNaam']; is getting a variable passed from a form I believe, second time someone goes to the page there will be nothing in it as that wasn't passed.
Next
if (isset($_COOKIE['Naam'])) {
$Naam = $NewNaam;
echo 'cookie exists' ;
Yes the cookie exists but you are setting $Naam = $NewNaam and $NewNaam doesn't have anything in it.
Try $Naam = $_COOKIE['Naam'];
I think you will find that works.
