Get array as post variable from textarea

How can I use a textarea to create an array in a post variable?

I want to be able to enter multible emails into a textarea and then submit the values to the action page as an array to be run in a SQL statment.

Any is much appreciated.

 

It's not something that can be done directly with the textarea. You need a server-side technology to break down the submitted string in the POST field. Most programming languages have a function that splits up a string. For example, to split by line in PHP:

$values = explode("\n", $_POST['email_addresses']);

Code (markup):

substitute whatever delimiting character you want into the first argument. Or you can use split() or preg_split() to split on regex if you want to support multiple delimiters.

 

Thank you for the response. I use coldfusion for my server script so i will do some more searching on how to create an array,

I know that I can create an array by using

<cfset my_array_name = ArrayNew[1]>

Code (markup):

Then I think I can maybe do:

<cfset my_array_name = #form.textarea_name#>

Code (markup):

not sure if this is going to break apart the data in the textarea though...

I have to do some more searching though,

thanks again.
