Why won't my code update or insert into Oracle DB when nested in if's?

Question

I am attempting to create code that takes user input via HTML form, and processes it using if statements (see below).

When I input data and click submit, no errors are reported. However, no data is updated in the oracle DB either. Next I will walk you through my logic, lines will be marked by /* ## */ to make it easier to understand.

So, the user inputs the week they are editing [/ 01 /]. Next is the day of the week they are editing (below / 01 /). These are the two values being used in the "if" statement (see handler) where my problem is.

Line designated / 02 / in handler is checking to see if there are any existing weeks matching that inputted by the user to edit.

Line designated / 03 / in handler beigns the if statement that takes $week , the row which may exist, and either edits or inserts depending on whether or not it is set.

There are 8 columns in this database: WEEK, and all days of the week (MONDAY, TUESDAY...SUNDAY).

Any help is greatly appreciated, TIA!

Form:

    <div align="center">
        <span style="font-size:60px;">
            Day to Day Tree Events - Update Page <br/>
            Be very cautious when editing this page. <br>
            Misformatting can cause data to be deleted or altered incorrectly. <br>
        </span>
    </div>

    <div align="center">

The following will always evaluate as true, you've missed out an equals sign.

if($week = 1)) {

ie, should be:

if($week == 1)) {

A single equals sign is an assignment, you are setting the variable week to 1 . This will always evaluate to true. A double equals sign is a comparison, you are comparing week to 1 .
