I put the setcookie on the
http://mysite.com?p=dashboard
page and it works just fine.

Thank you everyone for your help.
I am sure more questions shall come later 😉

I am using...
echo "<script>setTimeout(\"location.replace('http://mysite.com?p=dashboard')\",1000)</script>";
at the bottom of my login script.
What code can I use where a cookie will be set and I can move my user to a different page? 

Just testing this code and its not the issue.

back to the same problem.
It works fine on a blank document but when I put the setcookie code in with my login script the cookie does not set and I get the error about headers again.

OMG thank you so much it is working.

Polly got a cookie.

I put the set cookie at the top of the page and not in the body.

I am trying so hard to understand, I am.
If someone could provide code of a working example that would be grate to understand from there.

I now have this code on one page of my site...
setcookie("username", $new_cookie, strtotime( '+30 days' ), "/", "", "", TRUE);

and this code on a different page...
if(isset($_COOKIE['username'])){
echo "1";
}else{
echo "0";
}

my output is 0 every time.
I am not successful at setting my first cookie

I have played around with it some more but still get an error when only the line of code to set the cookie is there.
Also the line of code "echo" never works for me.
What am I doing wrong?

Error update.
Using this code...

$new_cookie = "123456789abcdefg";
setcookie("username", $new_cookie, strtotime( '+30 days' ), "/", "", "", TRUE);
echo $_COOKIE["username"];
echo "<br />";
print_r($_COOKIE);

the output is still an error.
 

I have a problem creating my first cookie.
I keep getting this error message and when I use...

echo $_COOKIE["username"];

I get nothing on the screen.
 

thank you so much.

Thank you.
 

What happens to the cookie when it hits 30 days old from my script?  

I see,
so to give my cookie an updated value will this code work?

setcookie("username", $old_cookie, strtotime( '-30 days' ), "/", "", "", TRUE);
setcookie("username", $new_cookie, strtotime( '+30 days' ), "/", "", "", TRUE);

Hi all,
I am coding cookies for the first time and here is what I have.

setcookie("username", $old_cookie, "1", "/", "", "", TRUE);
setcookie("username", $new_cookie, strtotime( '+30 days' ), "/", "", "", TRUE);

Is this the right way of resetting the value of one cookie?

ps. I did read a lot on http://php.net/manual/en/function.setcookie.php but it is not clear.

I was thinking of having 1 cookie array that has email, password, and id inside or should I use one cookie for each value?

would this code be a good way of keeping my users logged in for a long time?

if (isset($_SESSION['id'])) {
// check to see if user in logged in with session
// user continuous to be logged in code goes here	
}
else if (isset($_COOKIE["id"])) {
// if user session has ended but they still have a cookie
// auto login code goes here	
}else{
// send user to login page	
}

well how does Gmail and Facebook keep your sessions open for a very long time?

if I use...
 

ini_set('session.gc_maxlifetime', 86400);
session_set_cookie_params(86400);
session_start();

is it bad practice for keeping a session for a day?

Hi everyone,
I would like my sessions to time out after 7 days but they only last 30 minutes.
I am using php 7. Here is what I have...

php.ini - I always keep this file on the server

;register_globals = off
;allow_url_fopen = On

;expose_php = Off
;max_input_time = 60
;variables_order = "EGPCS"
;extension_dir = ./
;upload_tmp_dir = /tmp
;precision = 12
;SMTP = relay-hosting.secureserver.net
;url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset="

;memory_limit = 51M
;post_max_size = 10M
;file_uploads = On
upload_max_filesize = 7M
;max_execution_time = 7200
;max_input_time = 7200

session.gc_maxlifetime = 21800

how do I get my sessions to last longer that 30 minutes? 

lol.
got it!

lol, that's funny.

it is the last line...

var_dump($pic_array);

that is printing to the page.

How do I stop it and still have the code working?

Last question on this.

 

$pic_array = array_diff($pic_array, $remove);
var_dump($pic_array);

is printing the following to my page
array(5) { [0]=> string(1) "1" [2]=> string(1) "3" [3]=> string(1) "4" [4]=> string(1) "5" [5]=> string(1) "6" }

How do I stop it printing to my page?

thank you so much.

Thank you so much for the examples.
few more questions.
In my DB my array looks like
1,2,3,4,5,6,7,8,9
not
1, 2, 3, 4, 5, 6, 7, 8, 9
Is that a problem?

also 
can I change

$remove = [6];

to
 

$number_to_drop = '6';
$remove = [$number_to_drop];

?

 

Just got to the removing stage of my coding.
How do I find number 6 in my array and remove it?

$pic_array = "1,2,3,4,5,6,7,8,9";
$remove = "6";
if (in_array($remove, $pic_array)) { 
// ???
}

I found a method, coded it and it works.
Every image uploaded I added to an array I put in the DB.
Looking like this; 1,2,3,4,5,7,8,9
To view the images I used this...

$pic_array = explode(",", $pic);
foreach ($pic_array as $key => $value) {
$check_pic_array = 'pro_images/'.$id.'/pro'.$value.'.jpg';
if (file_exists($check_pic_array)) {
$pic = '<img src="$check_pic_array" style="max-width:100px; max-height:100px;" border="1">';

}
}

As you can see number 6 is missing. With this method it is easy to locate and remove unwanted files from the DB and server.

Thank you for your help. 

This is how I started the needed code but it is not working

$directory = 'pro_images/'.$id.'/casual';
if (file_exists($directory) && is_dir($directory)) {
$scanned_directory = array_diff(scandir($directory), array('..', '.'));
}
$scanned_directory2 = explode(",", $scanned_directory);
echo $scanned_directory2;

any help?

I have files that users upload.
1.jpg 2.jpg 3.jpg etc.
what if the best way of finding out what _.jpg are in a folder as users may delete an image.
