and another question..

i have a class:
class MembersType extends XoopsObject {
    function 
MembersType() {
        
$this->XoopsObject();
        
$this->initVar('tid'XOBJ_DTYPE_INTnullfalse);
        
$this->initVar('name'XOBJ_DTYPE_TXTBOXnulltrue100);
        
$this->initVar('climit'XOBJ_DTYPE_INTnullfalse);
        
$this->initVar('cname'XOBJ_DTYPE_TXTBOXnulltrue100);
    }
}


and in classhandler i want to use $this->getVar('name'); but that doesn't work, because $this directs to classhandler not class, so - how can i access needed variables using getVar ?
where's my red bull!

man, i solved this too..

i had to use already written function "get" like this:

$item $this->get($id);
$name $item->getVar('name');


and then getVar works like heaven!

how does this work? i mean how does foreach loop connects to the following operations? Variables $k and $v are not mentioned and yet somehow function can access variables like "$name", "$climit" etc..

foreach ($MembersType->cleanVars as $k => $v) {
            ${
$k} = $v;
        }

        if (
$MembersType->isNew()) {
            
$tid $this->db->genId('acc_member_type');
            
$sql sprintf("INSERT INTO %s (tid, name, climit, cname) VALUES (%u, %s, %u, %s)"$this->db->prefix('acc_member_type'), $tid$this->db->quoteString($name), $climit$this->db->quoteString($cname));}

if you have $k="foo", and you do ${$k}=$v;
then you have created a variable $foo=$v
this is usefull if u want to create variables named as the keys of an array automaticly

Thanks, that worked out!

How can i get actual results from "getObjects" function (it's in AccMembersTypeHandler class)?

function getObjects($criteria null$id_as_key false) {
        
$ret = array();
        
$limit $start 0;
        
$sql 'SELECT * FROM '.$this->db->prefix('acc_member_type');
        if (isset(
$criteria) && is_subclass_of($criteria'criteriaelement')) {
            
$sql .= ' '.$criteria->renderWhere();
            
$limit $criteria->getLimit();
            
$start $criteria->getStart();
        }
        
$result $this->db->query($sql$limit$start);
        if (!
$result) {
            return 
$ret;
        }
        while (
$myrow $this->db->fetchArray($result)) {
            
$MembersType = new MembersType();
            
$MembersType->assignVars($myrow);
            if (!
$id_as_key) {
                
$ret[] =& $MembersType;
            } else {
                
$ret[$myrow['tid']] =& $MembersType;
            }
            unset(
$MembersType);
        }
        return 
$ret;
    }


$class_handler =& xoops_getmodulehandler('memberstype');
$memberstype =& $class_handler->getObjects;

... what's next? i get $ret back, right? how can i get out results from that?


$ret is an array of $XoopsObject's, so you wil have your result like this:
$ret[0]=an Object;
$ret[1]another Object;
and so on.........

and another question just for confirmation.. when defining a function and putting for example $id = false in the brackets like this

getAll($id = false)

means that this attribute is not necessary when calling?


It means that you could pass the attribute when calling , but if you don't, it will be taken as false (in this case)

thanks for replies!

i've got some new question:

$this->db->getInsertid();

called this after INSERT query and no matter what the primary key value is, it returs 0.. what is wrong?

oh, the sql wasn't executed.. shame on me.

but what about db->getid()? this returns 0 every time, even user class, when inserting new user. so what's use of it?

[XOOPS 2.0.16]

Where do you see db->getid()?

XoopsMySQLDatabase::getInsertId() is defined in class/database/mysqldatabase.php, but I don't see a method named "getid".
