How To Add More Session Values?

[sonal]

I'm trying to work with php Sessions. My login script assigns some values to the session array. Now, after user logs in and goes further, I want to add other variables in that session. How can I add other values to an already started session? Is it possible?

[HartleySan]

If I remember correctly, sessions in PHP are handled through the $_SESSION superglobal, which is an associative array. That being the case, you can add to it as you please. For example:

 

$_SESSION['newValue'] = 24;

$_SESSION['anotherNewValue'] = 'Hamster';

 

That make sense?

I tried to do as HartleySan suggested. But, as I'm trying more and more with SESSION, it turns out that SESSION is an associate array, but special kind of.

It needs special handling. I understand this now, but still I'm unable to figure out(or search online) how to make/use a SESSION variable for this kind of work:

 

My login page assigns values to SESSION like this : $_SESSION['user_id']="9999"; $_SESSION['lname']="kkkkk" .

 

And after some activity I want to store another array of information for this user. I want a SESSION like this:

$_SESSION("user_id", "name", array("mid", mname, mlastname))...

 

How to add that array? Or how to start a SESSION like this so it can take in array later on?

So you'd do

$_SESSION['user_id'] = 9999; // Don't need to quote numbers.

$_SESSION['name'] = 'blah';

And then:

$_SESSION['something'] = array('mid' => 'value', 'mname' => 'value', 'mlastname' => 'value');

May be I'm doing something wrong. But when I add 'something', like this it gives error: undefined index "something".. It doesn't simply add that new array name, as session's new element..

Then you're definitely doing something wrong. You only get an undefined index error when you reference an array element that doesn't exist.

[sonal]

$_SESSION['something'] = array('mid' => 'value', 'mname' => 'value', 'mlastname' => 'value');

I got above code working. But then I realize, I need to store array of second array. Each user has multiple members. I tried to run following code, but it stores only the last "mid, mname" value from while loop? How to add array of array in already started session?

 

 

 

$smid = 0; // to give different index type value

//Fetch and print all records:

while($row = mysqli_fetch_row($r)) // from query run to fetch members under a user

{

 

// list out member names in a horizontal row:

echo '<tr class="rowA">';

echo '<td><a href="addbook9.php?id='. $row[1] .'&nm='. $row[2] .'"> '. ucfirst($row[2]) .'</a></td>'; //don't want to send id and name in url

//$mname = $row[1];

$mid = 'mid' . $smid; // this will give value like mid0, mid1....

$mname = 'mname' . $smid;

$_SESSION['members'] = array($mid => $row[1], $mname=>$row[2]); //want to store id, name in session to use later

$smid++;

echo '<td><a href="view_books.php?id='. $row[1] .'&nm='. $row[2] .'">' . $row[3] . '</td>';

echo '</tr>';

} //End of while loop.

 

echo '</table>';

<p>I changed above code as per following: </p>

<p> </p>

<div>$memids = array();</div>

<div>          $memnames = array();</div>

<div> </div>

<div> //Fetch and print all records:</div>

<div> <span class="Apple-tab-span" style="white-space:pre"> </span>  while($row = mysqli_fetch_row($r))</div>

<div>   {</div>

<div> </div>

<div>// list out member names in a horizontal row:</div>

<div>echo '<tr class="rowA">';                </div>

<div>                  echo '<td><a href="addbook9.php?id='. $row[1] .'&nm='. $row[2] .'"> '. ucfirst($row[2]) .'</a></td>';</div>

<div>                  array_push($memids, $row[1]);                          //add each id & name in another array.</div>

<div>                  array_push($memnames, $row[2]);</div>

<div>                 </div>

<div>                  $_SESSION['members'] = array('mid' => $memids, 'mname'=> $memnames);</div>

<div>                 </div>

<div> echo '<td><a href="view_books.php?id='. $row[1] .'&nm='. $row[2] .'">' . $row[3] . '</td>';</div>

<div> echo '</tr>';</div>

<div>   }    //End of while loop.</div>

<div> </div>

<div>echo '</table>';</div>

<div> </div>

<div>And it shows following result:</div>

<div> </div>

<div>Array ( [user_id] => 5 [fname] => SONAL [lname] => MACWAN [lid] => 1 [members] => Array ( [mid] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 8 [4] => 11 [5] => 12 ) [mname] => Array ( [0] => Stavan [1] => Ethan [2] => sonal [3] => daxesh [4] => Rupal [5] => Kavi ) ) )</div>

<div> </div>

<div>So, I am more confused now. How will I access each id-name pair? Is this the right way to add array of array into session?</div>
