Re: get session's problem

//To access XOOPS global variables, you need to include mainfile.php
//Change to path to mainfile.php
include('mainfile.php');

//Check if the current request comes from a XOOPS user
if ($xoopsUser) {
  //Person logged in
} else {
  //Person not logged in
}

$minUserLevel = 5;

//Check the current user's level
if ($xoopsUser->getVar('level') >= $minUserLevel) {
  //User is at the correct level
} else {
  //User is not at the correct level
}

//Get real db table name (adds XOOPS db table prefix)
$tblName = $xoopsDB->prefix('tablename');

//Make a database query
$sql = "SELECT * FROM $tblName";
$ret = $xoopsDB->query($sql);

//Loop through query results
while ($arr = $xoopsDB->fetchArray($ret)) {
  //Do something with each row returned
  echo($arr['field1']);
}


One word of caution though. If you are trying to use the level check to determine if the current user is an administrator, it will not work as expected. Only the admin user created during install will have a level of '5'.

A better way would be to check the user's group membership:
$groups = $xoopsUser->getGroups();

if (in_array(XOOPS_GROUP_ADMIN, $groups)) {
  //User is in the administrators group
}

It's really works!Thank you very much!

but i have another question...

if i login as 'ABC',and i transfer to the page i made,named 'manage.php'.i can check the user is xoops's user.When i echo (xoopsUser),it shows:

-------------------------------
code:
if ($xoopsUser) {
echo ("HI~$xoopsUser");
} else {
echo ("Sorry,NoPermission!");
}
-------------------------------

but it shows in web:


-------------------------------
HI~ Object
-------------------------------


If i want to query some data using this user's id,like:


select *
from members
where id='xoops user's id'

what should i fix this code?



Thanks again!

Re: get session's problem

as you found out $xoopsUser is an object. To be exact, it is an instance of the XoopsUser class. To access properties of the $xoopsUser object there are two handy functions:

$xoopsUser->getVar('varname');
$xoopsUser->setVar('varname', 'value');

each database field can be accessed through these two functions. So if the information you want to access is in the 'uid' database field:
$uid = $xoopsUser->getVar('uid');


in your two specific examples there are 3 different fields you may be interested in:

$xoopsUser->getVar('uname'); //The login name for the current user
$xoopsUser->getVar('name'); //The name of the current user (optional)
$xoopsUser->getVar('uid'); //The id of the current user
