bad fetch has ocurred Error when submitting responses

[tony]

Hi,

I am mystified with my Recording code, it does not work anymore, it used to work but I was kind of switching from ANSI to utf-8 codification and when I call the submit method to save Responses it just says a bad fetch error has occurred and I can't see where the problem is; is it a codification issue? or a syntax problem, I'd really appreciate your help.

Thanks,
Tony

Hi Tony,

When we did an initial review of your code, we discovered that your echo returning VXML within saveResponses.php was not completed escaped/closed. Specifically replace:

Code: Select all

<form id="form_main">

with

Code: Select all

<form id=\"form_main\">

as well as the final few lines:

Code: Select all

</vxml>
">\n";

with:

Code: Select all

</vxml>\n";

We will continue to look into this to see if we can find any other issues.

Regards,
Plum Support

Hi, thanks for the response I changed that section of the code to the code below where I am placing <form id="form_main"> outside of the php end sign ?> according to this tutorial http://www.plumvoice.com/docs/dev/devel ... erence:tts, and I was able to get rid of the the Bad fetch error message however, it does not prompt the goodbye message, how can I make it to prompt from a php file? In addition, I had to save this php file as a ANSI encoding file otherwise (utf-8) it still prompts a bad fetch error. Since I am using Spanish characters I think it should be Ok to save it as Utf-8 file, but it does not work. Again any help is appreciated.

Tony

Hi Tony,

Dealing with language encodings is pretty tricky. There are 3 pieces you'd want to look into.

• 1) Editor encoding
  2) PHP-level encoding
  3) XML-level encoding

1) Editor encoding - what is the encoding that your editor saves your files in?
Our engineers utilize a coding editor that allows you to manually adjust the encoding on a per-document basis. You'll want to ensure that the editor's encoding matches the encoding you will want to utilize. If you cannot modify the document encoding and your editor is saving the documents in a Latin-1 encoding you can replace the "utf-8" with "iso-8895-1" within our examples.

2) PHP-level encoding
This information can be set within the PHP header information.

Code: Select all

header('Content-Type: charset=utf-8');

3) XML-level encoding
This encoding would be set within the XML tag.

Code: Select all

echo "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n";

Once all 3 encoding levels match (you can utilize either Latin-1 or UTF-8 in this case) you should be able to fetch the script and hear the goodbye message be played.

Hope this helps.

Plum Support
