Using Arrays as Field Names - Validation bug?

[eluser]Vicente Russo[/eluser]
Hi,

On my last topic, I was trying to use dynamic validation, and I found using arrays as fieldnames worked for me. But when I repopulate the form, they return the string "Array" on every 'title[]' input, not the actual value.

Controller Code:

Code:

$this->form_validation->set_rules('title[]', 'Title', 'required');

View Code:

Code:

<input name="title[]" type="text" value="<?=set_value('title[]')?>" />
<input name="title[]" type="text" value="<?=set_value('title[]')?>" />
<input name="title[]" type="text" value="<?=set_value('title[]')?>" />

If I use

Code:

set_value('title['.$index.']')?>

Doesn't work. In the manual it says I have to use without the index:

"Or to re-populate the field you would use:"

Code:

<input type="text" name="options[]" value="<?php echo set_value('options[]'); ?>" size="50" />

So, can someone help me?

Thanks!

Hi there,

I also wanted to know how it can be done, and searched the forum and found your thread. Although I couldn't find any answers yet, here is what I did.

Base on your example:

Code:

<input name="title[]" type="text" value="<?=set_value('title[]')?>" />
<input name="title[]" type="text" value="<?=set_value('title[]')?>" />
<input name="title[]" type="text" value="<?=set_value('title[]')?>" />

Change to something like below:

Code:

<?php $title = set_value('title[]'); ?>
<input name="title[]" type="text" value="<?=$title[0]?>" />
<input name="title[]" type="text" value="<?=$title[1]?>" />
<input name="title[]" type="text" value="<?=$title[2]?>" />

I assume you are using a loop to output them, so continue from the above example base on your scenario, change from:

Code:

<?=set_value('title['.$index.']')?>

to something like:

Code:

<?=$title['.$index.']')?>

I am still figuring out how to output errors that ties to the specific item, as it will show the errors for all items if I use

Code:

<?=form_error('title[]')?>

I'm not sure if it is a bug, or just an oversight, but I came across a similar problem a while back, and then came up with a solution, maybe it will assist you too. http://ellislab.com/forums/viewthread/111929/
