Insert form arrays

[datadriven]

I have users doing Inserts from checkboxes, and have questions about the basic layout of the form.

a) Will this Insert in the column as an array, csv?:

<input type=checkbox name="form.col[]" value="1"> first >
<input type=checkbox name="form.col[]" value="2"> second >
<input type=checkbox name="form.col[]" value="3"> third >

b) how do I gather these for an Insert ( OnCLick=checkALL ?)

c) my forms will have a section like this, but others will have added sections on them, for checkbox values within other categories. How do you organize the OnCLick=checkALL for something like this?

e)Later, can a SELECT statement be done on these stored values in the col with "="?

Anyone know a decent tutorial on php checkbox forms for Insert? (Update too? -- will Update be workable if number values are stored in an array?)

[reminder]

for(reset($i); $i <= $_POST["form.col"]; ++$i) {
$hey = $_POST["form.col"][$i];
} 

cheers

reminder,

-excuse me but what does this do?

[reminder]

this grab the value from all checkboxes..
and if u want to check all checkboxes by clicking on a checkbox use this...

function checkAll() {
var hey = document.myForm.myCheckboxes;
for(i = 0; i < hey.length; i++) hey[i].checked = true;
}

cheers

reminder,

I'm kind of lost on all this, I know you're trying to help & I appreciate it. Do you know of a good tutorial that could walk me through doing more complex forms?

Still debating on whether I should try to Insert values into single column arrays because I really don't know how easy the values will be to work with;

-ex: SELECT and Like% //on the column when joined with other tables.

-Whether combined inserted values will be automatically seperated by spaces or commas, etc. I've only done basic Inserts and have been advised not to use Arrays in col's, since extracting/ recognizing values could be difficult.

For my forms, there are many disorderly values to place dynamically in sections on my differnet forms (which is what I wanted to Insert numeric array values into a single column). If I do many to many's (which I don't want to, these are single page forms) I'll have tens of thousands of rows on the Many to Many table before I can turn around. I'd rather store 12 values in a row rather than have 12 rows on a table.
