Question

I am trying to select a user id (uID) just to check if it exists… I am getting stuck at just the most basic select statement…

I’ve searched and tried different people’s code but either my code always returns true (if i dont use fetch) or it says that it is not an object and i cant not use fetch….

$sql = 'SELECT uID FROM ldc_user_details where uID=3';
$q = $this->db->prepare($sql);
$i=$q->execute();

     foreach ($i->fetch() as $key => $val){
      echo 'key='.$key." val =".$val;
     }

ERROR: Call to a member function fetch() on a non-object in /home/pdwdev/public_html/ldc_main.php

Answer 1

<?php

$sql = 'SELECT uID FROM ldc_user_details where uID=3';

// no need to use prepare() here unless there's a user input

$q = $this->db->query($sql);

// a check for rowCount would be good
if ($q->rowCount() > 0) {

    // all results will be in $i
    $i = $q->fetchAll();

     foreach ($i as $key => $val){

         echo "Key : {$key} <br> Val : {$val}";
     }
}
else {
    die("Zero Results returned");
}
