Post form fields into array help

condoug

Hi all

A user can choose a number between 1 and 10 from a list box. Based on the value of their choice I display the same form 1 - 10 times on the page and this form is there to collect personal data.

Each form will have a small number of text fields and also some checkboxes e.g:

name (text)
dob (text)
option 1 (checkbox)
option 2 (checkbox)
option 3 (checkbox)

(please note the checkboxes should be grouped as an array as they are dynamically built)

My question is, how do I 'group' each form field so that when the page is posted (saved) I can capture the correct data for each form filled in?

I know arrays are involved somewhere here but not sure how it is implemented.

Any help will be greatly appreciated.

Regards
Doug

I'm not 100% on what you're asking, but if you're trying to get all your check box values to come out in one array it would be something like this:

<input type="checkbox" name="my_array[]" value="3" />			
<input type="checkbox" name="my_array[]" value="2" />			
<input type="checkbox" name="my_array[]" value="1" />

The array will only have as many elements as boxes checked, and the elements will contain the checkbox value, so it's important the value is the unique identifier you use to tell you if that checkbox has been selected.

Using your example, yes, but that doesn't have to be the case. Example:

<input type="checkbox" name="my_array[0]" value="1" />            

<input type="checkbox" name="my_array[1]" value="1" />            

<input type="checkbox" name="my_array[2]" value="2" />

In other words, you can specify the keys of the array that PHP will create when the data is submitted.

Ah, interesting. Cheers for that.
I only use this method for my deletion option on a big table so I've never needed that sort of functionality.

in this case a two dimensional array will solve this problem.

<input type="checkbox" name="my_array[0][]" value="1" />            

<input type="checkbox" name="my_array[0][]" value="1" />            

<input type="checkbox" name="my_array[0][]" value="2" />

Where 0 will increase depending how many options selected previously.

Based on the value of their choice I display the same form 1 - 10 times on the page
