Checkbox Value: check, submit, change later (DB stuff)

[Daria]

Hi everyone!
I have a form with large amount of checkboxes.

1. checkboxes can be - surprise - checked and submitted into the database
2. checkboxes values should be retrievable if I run a SELECT query on the result, meaning if I come back to this form later, my previous selection displays as selected checkbox.
3. I want to be able to uncheck and re-check the checkboxes, to change my data.

I thought just doing this would be sufficient: (given I already ran the query to select data from the table, and did proper open/close of results display)

<input type="checkbox" name="230" value='<?php echo $row['230']; ?>

I can seem to figure it out... Can anyone give me an idea?
Thanks a bunch!

i'm not sure what value you are storing in the database? You need something like:

<input type="checkbox" name="230"<?php if($row['230'] == "true"){echo ' checked="checked"';} ?> />

Thanks, I'll try that.
