Hi
Need to get my head around checkboxes and the values they return, ive never really had to think about it but im writing a form script in php which places the all the post varibles into and array (in the order they are on the form) which is then pumped into my database,  i have a few check boxes which show and hide various bits of the form and which when selected return true (1) this identifys that for example, customer has a differnet billing address.

My issues arrises when i need the check box to return false, i cant really get my head around what is going wrong with my script but i cant seem to work it out.

1.
What do checkboxes return when they are not selected?

2.
Also whilst on the topic what are the x and y values that are posted that pop up when i create this array??

Many thanks

Sam

1) Checkboxes not selected are NOT submitted with the form

2) Are you using image for the submit button?

"In addition to sending the form data, the web browser sends the x,y coordinate of where the user clicked. If the image input is not given a name then the browser sends the x and y coordinates as the "x" and "y" input fields.

If the input image does have a name, the x and y coordinates are sent using the format name.x and name.y. For example, when you click on the submit image in this form, the coordinates are sent as MySubmitImage.x and MySubmitImage.y. This feature can be used to check which image was clicked. For example, suppose you want to have an image for "Yes" and another for "No". If you name them "Yes" and "No" you can check if they clicked "Yes" by checking for the existence of the "Yes.x" field in the data that is sent."

ok

So i have a couple of options,

1. work out a way to send null, if not selected. (is this possible?)

2. or add the varibles to the array if they are not set??

Thanks

1) you can put a hidden field with the default value BEFORE the checkbox so if the checkbox is not selected the hidden field will send the default value, if the checkbox is selected than the hidden field is ignored, both must have the same name.
