validation_errors() when using three forms in one view

[eluser]Casperlarsen94[/eluser]
How can i do so, when the validation in the first form not will be displayed in form number three and four?

I hope you understand me

You mean you have 3 forms and when you fill all the input
of all 3 forms and submit you get only error messages or
repopulated fields of one form?
If thats your case: you can validate and repopulate only
one form per time because only the data from the form you
submit is send to the controller.

I have three forms in ONE view file, and when i for example submit the second form, then my validation_errors(); in the view, print out the errors for form 2 in all three forms.

[eluser]Casperlarsen94[/eluser]
My page look like this: http://i1008.photobucket.com/albums/af20...dwwddw.png

When i'm posting one of the forms (all three of them have different form actions) then it print out the errors in all three forms.
I know it does it, because i use validation_errors(); in all three of dem.

Is there a way to do so it only print out they errors in the submited form?

Sorry for my english

Maybe you could set some if/else statemnts in your controller
and check which form was submitted. Set a hidden input field
for each form and check which form was send. Then in your
controller:

Code:

if ( isset($this->input->post('form_1')) and strlen($this->input->post('form_1'))>1)
{
// validate form 1
}elseif( isset($this->input->post('form_2')) and strlen($this->input->post('form_2'))>1)
{
// validate form 2
}elseif( isset($this->input->post('form_3')) and strlen($this->input->post('form_3'))>1)
{
// validate form 3
}

Didn't test that but it should work.

Three forms is the same as one form.

Each form has an action. It submits to a unique controller method.

Each method handles the appropriate form.

No conflicts.

Thanks for the answers.

I created a view to each form instead

This would work, but $this->input->post() will return false if it's empty or not set, so all you would need is:

Code:

if ($this->input->post('form_1'))
{
// validate form 1
}
if ($this->input->post('form_2'))
{
// validate form 2
}

I use this sometimes when I have 2 or more forms that post to the same controller.

Hello,

I am having similar issues, I am trying to understand how best to use form validation when there is more than one form on a page.

this solution seems to be the best idea although, I am not sure how to implement it, sorry for the dumb questions but I am still relatively new to CodeIgniter and MVC in general.

would it be possible to expand on this slightly

Jon, each form has an action attribute. That is, the address that the form submits to. In CI, your action submits to a controller/method.

If you have two forms on a page, simply set the form action to submit to the appropriate controller/method and process the form inputs as needed.
