trying to check whether a user exists or not via pdo
$wantedusrnm = $_POST['new-usrnm'];
$userExist1 = "SELECT * FROM users WHERE username=:wantedusrnm";
$userExist = $handler->prepare($userExist1);
$userExist->execute(array(':username' => $wantedusrnm));
$userExist = ($userExist->rowCount());
for some reason it errors, dunno why, any reasons?
Change:
$userExist->execute(array(':username' => $wantedusrnm));
To:
$userExist->execute(array(':wantedusrnm' => $wantedusrnm));
Because, in your query you've got :wantedusrnm but in your execution array you've got :username.

I'm trying to include a file to current php page but the name of the file depens on the lang.
This line does not work:
include_once PATH.'lang/'.$_SESSION['lang'].'.php';
How can I achieve that?
Your problem should be the "PATH". It must be a string to concatenate with the other strings. For example:
include_once '/sites/all/files/'.'lang/'.$_SESSION['lang'].'.php';
Also be careful with the slashes that make your path to the file.

i tried to debug it but i really don't know what's causing the error. i already traced the missing brackets but i think there's none. so please help!
<?php
class Model_role extends CI_Model {
public function scalar($user_account, $role){
$this->db->where('login_id', $this->input->post('idnum'));
$this->db->select($role); z
$query = $this->db->get($user_account);
$row = $query->row_array();
return $row['role'];
}
}
?>
It looks like there's a stray z way to the right of $this->db->select($role); Can you search for z in your editor and see if it comes up?

$managerID = preg_replace('#[^0-9]#i','',$_SESSION["id"]);

Can someone tell me what is wrong with that statement cause I do not see any mistake?
$PrevReleaseModel = $con->prepare("SELECT * FROM model WHERE model_name=:model_name AND model_release:model_release");
$PrevReleaseModel->bindParam('model_name',$model_name);
$PrevReleaseModel->bindParam('model_release',$model_release);
$PrevReleaseModel->execute(array('model_name'=>$model_name,'model_release'=>$model_release));
I am really confused.
WHERE model_name=:model_name AND model_release = :model_release
You missed a equal sign in the last condition.
You may try this out:-
$PrevReleaseModel = $con->prepare('SELECT * FROM model
WHERE model_name = :model_name AND
model_releas = :model_releas'
);
$PrevReleaseModel->bindParam(':model_name', $model_name, PDO::PARAM_STR);
$PrevReleaseModel->bindParam(':model_releas', $model_release, PDO::PARAM_STR);
$PrevReleaseModel->execute();

I am following video tutorials on the Internet, and this is one of them. However, I am getting a syntax error and can't find where it is.
<?php
function hesapla($ilktarih,$sontarih){
$yil=$son-$ilk;
$ay=$yil*12;
$gun=$ay*30;
return array("$ilktarih","$sontarih","$yil","$ay","$gun");
}
$ilktarih=$_POST["ilk"];
$sontarih=$_POST["ikinci"];
hesapla($ilktarih,$sontarih);
list ("$ilktarih","$sontarih",$yil,$ay,$gun)=hesapla($ilktarih,$sontarih);
?>
Remove double quotes from list variables like this :
<?php
function hesapla($ilktarih,$sontarih){
$yil=$son-$ilk;
$ay=$yil*12;
$gun=$ay*30;
return array("$ilktarih","$sontarih","$yil","$ay","$gun");
}
$ilktarih=$_POST["ilk"];
$sontarih=$_POST["ikinci"];
hesapla($ilktarih,$sontarih);
list ($ilktarih,$sontarih,$yil,$ay,$gun)=hesapla($ilktarih,$sontarih);
?>
