Deleting row from table in mysql database - mysql

Question

I am trying to delete a certain item from a database depending on conditions. Here is what I have:
while ($row = mysql_fetch_array($result)) {
$now = strtotime("now");
$dateArray = date_parse_from_format("n-j-Y", $row["date"]);
$event_date = strtotime($dateArray['year'].'-'.$dateArray['month'].'-'.$dateArray['day']);
// temp user array
$event = array();
if($event_date > $now) {
//Event is in the future
$pid_check =$row["pid"];
$event["pid"] = $row["pid"];
$event["name"] = $row["name"];
$event["longitude"] = $row["longitude"];
$event["latitude"] = $row["latitude"];
$event["pavement"] = $row["pavement"];
$event["traffic"] = $row["traffic"];
$event["environment"] = $row["environment"];
$event["image_b64"] = $row["image_b64"];
$event["date"] = $row["date"];
$event["time"] = $row["time"];
$event["type"] = $row["type"];
// push single product into final response array
array_push($response["events"], $event);
} else {
$result2 = mysql_query("DELETE FROM events WHERE pid = $pid_check");
}
}
But when I try this it comes up blank, when I comment out result2 it works but doesn't delete(duh). How can I get it to delete? Sorry if this is a simple question, my knowledge of the language is not much.

Answer 1

I think $pid_check is getting set only if the condition in your if is TRUE.
It's not getting set for the else branch.
One option is to relocate the assignment of $pid_check before the if test.
