Escape Characters and Quotation Marks - grahame - Apr 22nd, 2014
Hi
I am sure this is a problem common to many PHP installations but I was wondering how to fix it specifically in a form-tools installation?
I have a text area on a form. If I add
Quote:this is a quote by me; "why do I keep getting escape characters repeated?"
each time the submission is updated I get extra escape characters
Quote:this is a quote by me; \\\"why do I keep getting escape characters repeated?\\\"then, after 3 or 4 updates
Quote:this is a quote by me; \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"why do I keep getting escape characters repeated?\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"
To get around storage of this I use stripslashes and str_replace functions in a hook in ft_update_submission, start. But although it is getting stored correctly in MYSQL it still insists on displaying them as above?
Is there is a global variable or whatever that I can set to prevent this behaviour rather than use code hooks?

I have solved this problem but it took some finding.
I have a code hook in ft_update_submission,start. Although it appeared to be working there must have been a problem with it. However this problem was not flagged in edit_submission.php i.e.
Code:
list($g_success, $g_message) = ft_update_submission($form_id, $submission_id, $request);
// if there was any problem udpating this submission, make a special note of it: we'll use that info to merge the current POST request
// info with the original field values to ensure the page contains the latest data (i.e. for cases where they fail server-side validation)
if (!$g_success)
{
$failed_validation = true;
}Both $g_success and $g_message were being returned as NULL. Later in edit_submission.php there is a call thus:-
Code:
$grouped_fields = ft_get_grouped_view_fields($view_id, $tab_number, $form_id, $submission_id);
if ($failed_validation)
{
$grouped_fields = ft_merge_form_submission($grouped_fields, $_POST);
}Because $failed_validation was true, the merge code here (I think) just kept adding the POST'd values to themselves and (I think) was causing the multiple slashes to appear.
I corrected my hook and everything behaved itself again
I wonder if this should be flagged up to Ben/Joe??

Hi
Would be happy to but, actually, I have done a little more digging around on this.
I had code in the hooks manager for 'ft_update_submission, start' and 'end'. When ft_update_submission was called by edit_submission.php thus
Code:
list($g_success, $g_message) = ft_update_submission($form_id, $submission_id, $request);Now although my code was actually working, there are two override variables in the hook manager... $success and $message which I was not manipulating. They were defaulting to NULL.
So I don't think this is a bug per se but rather my misunderstanding that there was a requirement for $success and $message to be set to true by the code in the hook??
