variabelen aftrekken
het lvl van het ene persoon is hoger dan het andere dus ik wil niet dat de laagste iets van de hoegere kan veranderen ik heb tot nu toe:
$lvlnumber = 2;
$lvlnumber2 = 0;
$number = $lvlnumber - $lvlnumber2;
echo $number;
maar hij geeft geen waarde trug wat is er nou fout?

while ($result=mysql_fetch_object($result))
{
$lvlnumber = $result->lvl;
}
$result2=$db->do_query("SELECT * FROM members WHERE user='".$variabele."'");
while ($result2 = mysql_fetch_object($result2))
{
$lvlnumber2=$result2->lvl;
}
en $variabele is het bersoon bij wie de user iets wil gaan veranderen

$result=$db->do_query(
en
$result=mysql_fetch_object(
geef één van de twee een andere naam.
Edit: Bij $result2 doe je dat ook.

ik heb er nu $resultaat en $resultaat2 van gemaakt maar dan werkt ie nog niet :'(

als hij op edit duwt krijgt de $variabele als waarde de naam van de user (die veranderd kan gaan worden)

In het veld 'user' kunnen daar dubbele namen in voorkomen? En wat zou het verschil tussen die twee queries moeten zijn?
Edit: Typo

SanThe:
Ik snap er niks meer van.
In het veld 'user' kunnen daar dubbele namen in voorkomen? En wat zou het verschil tussen die twee queries moeten zijn?
In het veld 'user' kunnen daar dubbele namen in voorkomen? En wat zou het verschil tussen die twee queries moeten zijn?
Zelfde vragen. Ik begrijp van dat script niks. Er komt onder andere een $variabele in voor die nergens wordt gedefiniëerd.
$result3=$db->do_query("SELECT * FROM members WHERE user='".$variabele."'");
Het level van de ingelogde user wordt gezocht met deze query:
$result=$db->do_query("SELECT * FROM members WHERE user='".$_SESSION['user']."'");
($_SESSION['user'] is de sessie die ik aanmaak als iemand zich inlogd
$resultaat->lvl en $resultaat3-> worden omgezet in getallen:
recruit apprentice Lord en Lady worden 0
Druid of time en sister of the leaf worden 1
Arner en Arnea worden 2
die worden dan met elkaar vergeleken door:
if ($_SESSION['lvlnumber'] - $_SESSION['lvlnumber1'] < "0" OR $_SESSION['lvlnumber'] - $_SESSION['lvlnumber1'] == "0")
als ze kleiner of gelijk zijn dan 0 krijg je de foutmelding dat je t niet mag veranderen
ik hoop dat dit hielp
volgens mij trekt ie altijd alleen maar string uit de db.
ik heb de if ($_SESSION['lvlnumber'] - $_SESSION['lvlnumber1'] < "0" OR $_SESSION['lvlnumber'] - $_SESSION['lvlnumber1'] == "0")
in het else deel van een andere if gedaan dus lukte het niet echt sry niet slaan ik weet dat dit er nu al heel erg dom uit ziet
