Hmm, can’t find (grep) template_post_parse anywhere in CT, also for tempalte_post_parse in exp_extensions I have only two things, Mo variables and stash (both set to 10).
However, a re-direct is definitely being used, and is flashdata…basically, this seems to to be the error handling bit in CTs form builder:
public function action_complete($validate = FALSE, $secure_forms = TRUE)
{
$this->EE->load->library('javascript');
//dumb stuff for ee2.1.3
if ( ! isset($this->EE->security) || get_class($this->EE->security) !== 'EE_Security')
{
require_once APPPATH.'core/EE_Security.php';
$this->EE->security = new EE_Security;
}
if ( ! $this->return)
{
$this->return = ($this->EE->input->get_post('return')) ? $this->EE->input->get_post('return', TRUE) : $this->EE->uri->uri_string();
}
$url = $this->parse_path($this->return);
if ($this->is_secure() || $this->bool_string($this->EE->input->post('secure_return')))
{
$url = $this->secure_url($url);
}
$flashdata = array(
'success' => ! $this->errors(),
'errors' => $this->errors(),
'return' => $url,
);
if (AJAX_REQUEST && $this->EE->config->item('secure_forms') === 'y')
{
$flashdata['CSRF_TOKEN'] = $this->EE->functions->add_form_security_hash('{CSRF_TOKEN}');
}
//temp. store the current value of end_script, in case this call is nested inside another hook's call
$end_script = $this->EE->extensions->end_script;
foreach ($flashdata as $key => $value)
{
$this->EE->session->set_flashdata($key, $value);
}
if ($this->EE->input->post('ERR'))
{
$this->set_show_errors($this->bool_string($this->EE->encrypt->decode($this->EE->input->post('ERR')), TRUE));
}
if ($this->errors())
{
$this->callback($this->error_callback);
if ($this->show_errors && ! AJAX_REQUEST)
{
if ($this->EE->input->post('error_handling') === 'inline')
{
foreach ($this->values as $key)
{
$value = $this->EE->input->post($key);
//custom_data[foo] => custom_data:foo
if (is_array($value))
{
foreach ($value as $k => $v)
{
$this->add_form_variable($key.':'.$k, $v);
}
}
else
{
$this->add_form_variable($key, $value);
}
}
$method = (version_compare(APP_VER, '2.1.3', '>')) ? 'generate_page' : '_generate_page';
$this->EE->load->add_package_path(PATH_THIRD.'cartthrob/');
$this->EE->core->$method();
$this->EE->extensions->end_script = $end_script;
return;
}
// if this is not loaded.... then the user_message template can not be output as part of show_error 2.6x
// basically the exception class's show_error looks to see if TMPL is set... if not it outputs the general_error.php file... which we don't want.
if ( ! isset($this->EE->TMPL))
{
$this->EE->load->library('template', NULL, 'TMPL');
}
// since we'll be removing post in a minute, I'm creating temporary variables to store some stuff that would otherwise rely on post's existance
$errors = $this->errors();
$error_header = $this->error_header;
if (!empty($_POST))
{
unset($_POST); // we're unsetting post because show_error... a near useless function that is intended to replace show_user_error will otherwise insert a javascript back link which will then be replaced with [removed] link and will show some effed up code. show_message function of EE's output class basically has a bug. If that gets fixed, we can undo this so that the back link will be shown correctly. FOr now, removing $_POST will remove the bad back link.
$_POST = array();
}
return show_error( $errors, $status_code = 500, $error_header);
}
}
/*
if ($secure_forms && ! $this->EE->security->secure_forms_check($this->EE->input->post('csrf_token')))
{
if($this->EE->input->post('RET'))
{
$this->EE->functions->redirect(stripslashes($this->EE->input->post('RET')));
}
}
*/
if ( ! $this->errors())
{
$this->callback($this->success_callback);
}
//$url = $this->EE->functions->create_url($this->return);
$this->EE->functions->redirect($url);
}
I’ll try with the alternative methods of injecting the content etc, and simplifying, but thought I’d get this going as it might be a clue.
