set_value() in CI3 has issues with input arrays - zknight - 10-14-2016
In Codeigniter 2 our forms were able to have
PHP Code:
<input type="text" name="options[]" value="<?php echo set_value('options[]'); ?>" size="50" />
<input type="text" name="options[]" value="<?php echo set_value('options[]'); ?>" size="50" />
The error
PHP Code:
A PHP Error was encountered
Severity: Notice
Message: Array to string conversion
I did look at the form_helper from CI2 and I saw it parsed out the values if it saw an array and returned them differently than they are being done in CI3.

hi - hey i can confirm this does work for me in CI 3 so there must be something else going on. Are you using CI form validation? Are you sure you have 'field' => 'options[]' in the form validation? Are you sure you are loading form helper? If none of those things solve it then try naming the field something different then 'options' - maybe you have a conflict. And if that does not work then post more of your code and the specific error messages you are getting.

Not sure what you mean by 'field' => 'options[]'?
I use
PHP Code:
$this->form_validation->set_rules('options[]', 'Options', 'required');
I'm referencing https://www.codeigniter.com/userguide3/libraries/form_validation.html#using-arrays-as-field-names for this post by the way. Also, there is no other error messages, it's just that set_value() returns the whole array instead of the individual fields. Also, I'm using form_validation obviously and form_helper is loaded automatically(unless this changed in CI3) when you load that library.

i think you do need to load the form helper - or at least it shows doing that in the form validation example in the manual.
https://www.codeigniter.com/userguide3/libraries/form_validation.html#the-controller
personally i would just autoload form helper and url helper in: application/config/autoload
then you don't have to worry about it.

Check your PHP version and make sure your running PHP 5.6 or newer.
