form_input with id as an arrays and form_prep - El Forum - 07-18-2012

It's easiest if I explain this by putting everything useful in a view:

Code:
&lt;?php

        $this->load->helper('form');

        $conf   =       Array(

                0       =>      array(

                        'description'   =>      '14" Ladder'

                ),

                1       =>      array(

                        'description'   =>      '14" Ladder',

                ),

        );

        foreach ( $conf as $line )

        {

                $desc   =       $line['description'];

                echo form_input("description[]", $desc, 'class="span1"') . "<br/>\n";

        }

?&gt;

The above code produces two input fields on the page, the first of which contains the pre-filled text 14" Ladder. The second contains the text 14.

If I replace the input-as-array part with individual fields:

Code:
$count = 0;

        foreach ( $conf as $line )

        {

                $desc   =       $line['description'];

                echo form_input("description$count", $desc, 'class="span1"') . "<br/>\n";

                $count  +=      1;

        }

Then all the text is pre-filled correctly.

If I attempt to form_prep the $desc value manually with description[], it produces some messy results both in the front end and the saving back end.

Is this actually a bug? I had a hard time searching for the best way of describing this, so it's more than likely I missed something (there were older posts about form_prep and quot for example). The code does work, so long as the form_input isn't an array.

For the moment I think the best work around is to manually form_prep the data and not use form_input for this field, but if I could get it working properly that would be so much cleaner.
