Best Fix Found for Random Deletions in "Classes" Database?

Hi,

Random and completely unasked for delections have been occurring in my "Classes" database.
I would like to know if I have correctly analysed and handled the situation.

I first filter on SecurityAssist_ID to create a "View" page of all classes per each Presenter.

I then drill down to details per each specified class on an "Edit" Page using:

edit_class.php?ClassID=<?php echo($rsGetClassInfo->getColumnVal("ClassID")); ?>

This (of course) gives me a:
$_GET['ClassID'],
to go with that
'ClassID=xxxx'.

But if a Presenter merely looks at the page then backs out (doing nothing), the record was deleted.
I decided that this was probably because nothing or null was somehow being used as an unauthorized value for an update.

I then noticed MySQL's coding for the Update begins with:
if (true) {
blah blah blah;
}

I therefore amended this to:

<?php
if (isset($_POST["ClassLength"])) {
blah blah blah
}
(with there being a different such page for every class attribute, that Post being linked to the ClassID from the GET).

It may be a coincidence, but there has not been a repeat since. So unless I am mistaken, amending that "if" clause cured the problem.

Does this mean I must in the future amend all such "if (true)" MySQLi update queries that involve a ?ClassID = xxxx appended to the URL?

This is surely such a common scenario that it seems strange it should be so?
But if it is so, then I am sure my above code fragment is primitive in the extreme.
Could you please suggest what more auspicious expression I should be using?

Thank you,
KAB

The IF statement is the trigger that causes the action to take place. In every application it could be different. Without looking at your code in context I really couldn't determine if or why you should be using one trigger over the other.

In general if (true) means to run every time the page loads. If it is an insert or update, usually it will refer to the form button and a $_POST value so that it only runs when the form is filled out and doesn't run twice (once when the page loads and another time when the form is submitted)
