checkboxes

could somebody give me an example regarding how to handle a checkbox in a PHP form.

Like, i want to place couple of checkboxes in one of my form, for example:Studentenrolment,feepaid:
when i try to insert a student record into the students table, depending on the condition, i might check both the checkboxes or 1 or leave both empty.But, the value should be stored in the table.
how can i do this one.could somebody give me the code.

thanks in advance

<input type="checkbox" checked name="whatever" value="whatever">

??

Technically, according to W3C standards, that should be:

But that's just me being pedantic, lol. ;)

I'm trying to insert records into a table.

I've these two checkboxes in a form.

When i check these 2 checkboxes and insert the record into a table, it works pretty fine.IF I LEAVE ONE OR BOTH OF THESE CHECKBOXES UNCHECKED,it produces me an error:"Conversion from string".

To avoid this error, i tried to place the following two st's before the sql insert statement.

But, it still gives me the error.

I feel that if the checkbox is checked, the value 1 will be inserted into the column or 0.

Does'nt it sounds meaningful??

Ps:Stdcount is an array.I guess, there is nothing to do with that.
I tried removing spaces and so on, but still, itz the same.
So, any idea behind this error??

Thanks everybody.

Try adding in a few print_r()s and echo()s and see if that throws up anything unexpected - that's usually the best way to debug...
