codeigniter - How to make array of textbox fields in PHP? -

i'm using codeigniter framework.

i'm using form_input function make 2d array of textboxes , pulldowns.

the function produces html this:

<input type="box" name= "variable"> 

i need create 30 rows of 5 textboxes (time, event, supplies, sucess{yes/no}, comment).

my plan somehow able uniquely identify them @ later stage when $post them page wont confused textbox time1 or textbox time2.

i'm trying make array of texboxes in php when use for loop (isset) can stop when row not completed user.

this code here im not sure if spot on

for ($i =0; $i< 30; $i++) {     //time part of event field     echo form_input ($events['time',$i]),      //the event     form_input ($events['event',$i]),      //supplies used     form_input ($events['supplies',$i]),     //successful?     form_dropdown ($events['success',$i] $success),     //comment if necessary     form_input ($events['time',$i]);     echo '<br/>'; } 

i don't understand either regarding $_post object; ci docs:

codeigniter comes 3 helper functions let fetch post, cookie or server items. main advantage of using provided functions rather fetching item directly ($_post['something']) functions check see if item set , return false (boolean) if not. lets conveniently use data without having test whether item exists first. in other words, might this:

if ( ! isset($_post['something'])) {     $something = false; } else {     $something = $_post['something']; } 

with codeigniter's built in functions can this:

$something = $this->input->post('something');
