I am trying to delete a record from a simple sql table. I want to be able to delete using the primary key of the table which is

diaryID

and the table name is

digitalDiary

I can not retrieve the ID from the code I am using to be able to delete the entry.

What I have tried:

<?php
include ("dbConnect.php");
$diaryID = $_GET["diaryID"];
var_dump($diaryID);
$sql = "DELETE FROM digitalDiary WHERE diaryID=:diaryID";
$statement = $conn->prepare($sql);
if ($statement->execute([':diaryID' =>diaryID])) {
  header("Location:digitaljournalindex.php");
}
?>

You check for the value of $diaryID but don't tell us what you see.
Guessing from your context, it would seem it's not the correct value (or any value at all).

You also didn't explain how you get to the php that retreives $diaryID.
Did you:
check that you're actually sending the value via 'diaryID' ?
check that the symbol names are absolutely identical?

If AJAX, then did you actually build it into the AJAX call?

Give us a little more info!
