For a school task i am working on I've been writing a while loop which should loop until the condition is reached, but when i launch the website it doesn't go until the condition is met is just loops once. Does anyone know why this could happen?
Code:
function Som($Pdo){
$Stmt4 ='';
$Stmt5 ='';
$Tetter ='nee';
while($Tetter == 'nee'){
$I = 1;
$I++;
echo $I;
$Stmt = $Pdo->query('SELECT max(OpdrachtID) AS opdracht FROM opdracht ');
$QuestionID = $Stmt->fetch();
$Rand = rand(1, $QuestionID['opdracht']);
$Stmt2 = $Pdo->query("SELECT Opdracht FROM opdracht WHERE OpdrachtID =".$Rand." AND GroepID = 2 AND OpdrachtSoort = 'Multi'");
$D1 = $Stmt2->fetch();
$Opdracht = $D1['Opdracht'];
$Stmt3 = $Pdo->query("SELECT Antwoord FROM opdracht WHERE OpdrachtID ='.$Rand.' AND GroepID = 2 AND OpdrachtSoort = 'Multi'");
$D2 = $Stmt3->fetch();
$Stmt4 = $Pdo->query('SELECT GroepID FROM opdracht WHERE OpdrachtID ='.$Rand);
$Stmt5 = $Pdo->query('SELECT OpdrachtSoort From opdracht WHERE OpdrachtID ='.$Rand);
$Antwoord = $D2['Antwoord'];
$S89 = $Stmt4->fetch();
$S8 = $S89['GroepID'];
$S98 = $Stmt5->fetch();
$S9 = $S98['OpdrachtSoort'];
#echo $S8;
#echo $S9;
$returnWaarde['vraag'] = $Opdracht;
echo $returnWaarde['vraag'];
$returnWaarde['antwoord'] = $Antwoord;
if($S8 == 2 && $S9 == 'Multi'){
$Tetter = 'ja';
echo $Tetter;
}
else{
$Tetter = 'nee';
echo $Tetter;
}
return $returnWaarde;
}
}
There are multiple bits of code here showing if everything is working correct, of which. $I is always 2. $Tetter sometimes shows 'ja' but most of the time 'nee'
I know it's a bit messy but I've been working on this one part for a while now.
I would probably make all in one select, but ok.
Your
return $returnWaarde;
Is in the While loop it must be be after the closing paragenesis of the while loop.
