I am currently working on a project for a client but because I am new to pdo I have no clue how to hand the error it keeps spitting out. The code I am working with is not mine either, so that adds a bit of confusion to the mix. It keeps telling me:
Query failed: You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server
version for the right syntax to use near '' at line 1
I have narrowed down the error to these lines:
$regid = $dbh->lastInsertId('');
$dupsid = true;
while ($dupsid){
srand((double)microtime()*1000000);
$maxrand = 100000000;
$rand_sid = rand();
$check_sid = "select reguniqid from v_events_registrants where reguniqid = :RAND_SID";
$stmt = $dbh->prepare($check_sid);
$stmt->bindValue(':RAND_SID', $rand_sid);
$stmt->execute();
$num_result = $stmt->rowCount();
if ($num_result == 0) $dupsid = false;
}
$uniqid_upd = "update v_events_registrants set reguniqid = :RAND_SID where registrant_id = :REGID";
$stmt = $dbh->prepare($uniqid_upd);
$stmt->bindValue(':RAND_SID', $rand_sid);
$stmt->bindValue(':REGID', $regid);
$stmt->execute();
in this case here $reg is the primary key of the table in which the last few items were added. Initially I thought that was the issue but when I cleared it of ', and " I get an invalid id error, which I am guessing is from the next execution of the pdo. Please help as this error is really starting to hold me back from completing this project for my client.
