[SOLVED] Form Handling - Dealing with "Check Boxes"

[stublackett]

Hi,

 

I've got a form setup, Where the user can tick to make the car they are adding to the site Car Of The Week... This will then input a value of 1 into the Database.

 

That works when the box is ticked, But when its not ticked I'm getting PHP Errors of the variable being undefined... How do I change that undefined to a 0?

 

<form action="addcar.php" method="post" enctype="multipart/form-data">
<h2>Add a new car</h2>               
<ul>
<li><label>Car Name : </label><input type="text" name="carname" tabindex="1" /></li>
<li><label>Cars' Description : </label><textarea name="description" cols="40" rows="5" tabindex="2"></textarea></li>
<li><label>Price : </label><input name="carsprice" type="text" tabindex="3" id="carsprice" />
<li>
<li><label>Feature 1 : </label><input name="feature1" type="text" tabindex="4" /><em>Car feature i.e ABS</em></li>
<li><label>Feature 2 : </label><input name="feature2" type="text" tabindex="5" /><em>Car feature i.e ABS</em></li>
<li><label>Feature 3 : </label><input name="feature3" type="text" tabindex="6" /><em>Car feature i.e ABS</em></li>
<li><label>Feature 4 : </label><input name="feature4" type="text" tabindex="7" /><em>Car feature i.e ABS</em></li>
<li><label>Feature 5 : </label><input name="feature5" type="text" tabindex="8" /><em>Car feature i.e ABS</em></li>
<li><label>Image 1 : </label><input name="image1" type="file" /><em>* This is the main image that will appear on the site</em></li>
<li><label>Image 2 : </label><input type="file" name="image2" /></li>
<li><label>Image 3 : </label><input type="file" name="image3" /></li>
<li><label>Image 4 : </label><input type="file" name="image4" /></li>
<li><label>Make Car Of The Week : </label><input name="caroftheweek" type="checkbox" value="1" />
</li>
<li>
<input type="submit" name="submit" id="submit" value="Submit" />
<input type="reset" name="reset" id="reset" value="Reset" />
</li>
</ul>
</form>

 

The Form Field is titled caroftheweek

just run a check first thing when submitting

if ($caroftheweek!=1)
{
$caroftheweek=0;
}

 

or

 

if (!isset($caroftheweek))
{
$caroftheweek=0;
}
