How to custom Redirect?

Hi,

In my form a user needs to agree or disagree (Yes/No) and based on that answer the user is redirected to a another form.

I use Custom Code:

if ($_POST['Yes']) {
$formname = 'ABC';
}
if ($_POST['No']) {
$formname = 'DEF';
}

In Redirect URL:

Target URL: index.php?option=com_chronoforms
Params: chronoform={$formname}

Redirect User I leave empty.

After submitting the form I get the error: Form name can NOT be empty!
It seems that the param $formname form the Custom Code is not being transferred to the Redirect URL. Any suggestions?

Hi Robin,

There are several things that need fixing here:

How are you setting the Yes/No question in the form? Is it with Radio buttons? Or do you really have two inputs nmed Yes and No? I'll assume that is radion buttons named 'yes_no'

The ReDirect URL action:[list]

reads values from the $form->data array; so you need to add your 'formname' to this array.

doesn't read curly brackets (it only accepts names from the $form->data array)

needs all of the options in the ParamsFields box (and not in the Target URL)

[/list]

Putting all of these together change your Custom Code to

<?php
if ( $form->data['yes_no'] == 'Yes' ) {
  $form->data['formname'] = 'ABC';
} else {
if ($_POST['No']) {
  $form->data['formname'] = 'DEF';
}
$form->data['set_option'] = 'com_chronoforms';
?>

and in the ReDirect URL action the Target URL is 'index.php' and the Params Fields box

option=set_option
chronoform=formname

Hi Bob,

The Yes & No are both submit buttons with the names 'Yes' and 'No'. Therefore I use

If 'Yes' button is clicked:
if ($_POST['Yes'] )

If 'No'button is clicked:
if ($_POST['No'] )

In Custom Code I now have:

<?php
if ( $_POST['Yes']) {
  $form->data['formname'] = 'ABC';
} 
if ($_POST['No']) {
  $form->data['formname'] = 'DEF';
}
$form->data['set_option'] = 'com_chronoforms';
?>

Maybe I need to change this in: (?)

<?php
if ($form->data['Yes']) {
  $form->data['formname'] = 'ABC';
} else {
if ($form->data['No']) {
  $form->data['formname'] = 'DEF';}
}
$form->data['set_option'] = 'com_chronoforms';
?>

I use the params as you suggested. The Redirect Url will be :
index.php?option=set_option&chronoform=formname

It seems that both params ($form->data['formname'] and $form->data['set_option']) are not set in the custom code. This is strange even while the param $form->data['set_option'] is not in the IF-loop.

Hi Bob,

I've used the Debugger after the Custom code and this replies with:

Array
(
    .....
    [Yes] => Ik wil graag verder
    [formname] => ABC
    [set_option] => com_chronoforms
)

redirect_url
redirect_url_target_url: index.php
Redirect URL: index.php?option=set_option&chronoform=formname

This means that the params are being set in the Custom Code but they are not being read in the Redirect URL.

Should I use Curl instead?

Hi Robin,

I'm lost between the various versions here. Please take a Form Backup using the icon in the Forms Manager and post it here (as a zipped file) or PM or email it to me and I'll take a closer look.

Use cURL if you want to send the data but keep the user on your form page; if you want to redirect the user then the ReDirect URL and ReDirect user is the right set of options.

Bob

Hi Bob,

Thanks for taking a closer look. I'll send you the zipped form by PM.

Robin

Hi Bob,

I've found the solution so you don't need to figure out my form :-)

The solution is to change the params in the Redirect URL to:

option={set_option}
chronoform={formname}

Now it works!

Thanks again.

Robin

Hi Robin,

Ah, excellent. I knew that was how the ReDirect URL **should** work but I didn't remember that it did that and the Help doesn't say anything about curly brackets.
