Populate a checkbox or radio button

Anon

Ok this seems to be easy but for some reason I can't do it

Here's what I think

I have Three checkboxs all named set1

the values are seta, setb, setc

So i use

$set1 = isset($set1);

then i use a update statement to update the database no problem

ok here comes the problem

If I go back to the form I want to know if I check the box so it should be checked but it's not I guess my question is How do I get it checked

Since there are three check boxes that you can choose from how do you set the values to insert into the database but also know that its been check

hope you understand this

Thanks for any help

i am not very clear of your problem, but i can see one thing about the name of the checkboxes.

you need to give it name like set1[]. when you submit the form, php will treat it as an array, so your values seta, setb etc. will be in set1[0], set1[1] etc.

upon submit count the number of entries in an array by $num_of_rows = count($set1);

and then use FOR loop up to the total number of rows, and execute the UPDATE statement for each of $set1[$i] where $i is your auto increment in FOR loop.

hope this is some help.

First off, checkboxes must have unique names.
Only radiobuttons share a common name.

I'm not sure if daarius' solution works for checkboxes too, but it should work for
selectboxes.

In HTML you can make a checkbox or radiobutton appear "selected" by adding "checked" in the tag, like this:

(some other form elements use "selected", you may have to look them up)

So when you diplay the form after the database update, use an IF statement
to check and uncheck the boxes using the data from the database.
