How to add signature pad in a form?

Hi Christophe,

Please use the Signature element from the Widgets group in the Designer tab.

Thanks Bob,
I didn't see it before...
Best regards

How to recover the signature, please?
{data:signature} produces an encoded image in the html
{var:signature} in attached file -> error no email
​
Thanks

Hi Christophe,
​

$this-> and no $form->
All works except the attached file, i think it comes from the code $form->files...
I tried $this-> but not
Do you have any idea?
​
<?php
$data_pieces = explode(",", $this->data[signature]);
$encoded_image = $data_pieces[1];
$decoded_image = base64_decode($encoded_image);

// set the folder where the images will be saved
$folder = 'images/signatures/';
$path = JPATH_SITE.'/'.$folder;
$url = JURI::root().$folder;
// sets a file name using a date-time prefix to make sure it is unique
$sig_name = date('Ymd-his').'_signature.png';
file_put_contents( $path.$sig_name, $decoded_image);

// add the file info to the form data
$this->data['signature'] = $sig_name;
$form->files['signature']['name'] = $sig_name;
$form->files['signature']['link'] = $url.$sig_name;
$form->files['signature']['path'] = $path.$sig_name;
// display the image if needed
echo "<img src='{$url}{$sig_name}' />";
// to add the image to an email add this line
// and put {sig_img} in the email template
$this->data['sig_img'] = "<img src='{$url}{$sig_name}' />";
?>

Hi Christophe,
​
I was able to display an image by replacing the last five lines (starting //display this image) with

return $url.$sig_name;

and then using this in a Custom Code action

<div><img src='{var:php6}' /></div>

where php6 was the name of my PHP action.
​
This should also work in an email body - my tests have not been delivered for some reason though the Debugger shows success.

Hi Bob,
Display image works well.
Only add file to email doesn't work.
​
$form->files['signature']['name'] = $sig_name;
$form->files['signature']['link'] = $url.$sig_name;
$form->files['signature']['path'] = $path.$sig_name;
​
I think it's not : $form->files
​

Hi Christophe,
​
It is not $form->files - but I can't work out what it is.
​
In my test I tried adding the display div in the email body - I think that should work OK.

Hi Bob,
Save to directory and img in mail works well.
only attached file doesn't
regards
Chris

Hi Christophe,
​
Please try this version - replace the 'return' section of the PHP code with this:

// add the file info into the form data
return array(
  'url' => $url.$sig_name,
  'path' => $path.$sig_name
);

Then you can use {var:php6.path} in the email body or to display on the site as before and {var:php6.url} in the Attachments list of the Email action. (Replacing php6 with the name of your php action.)
