[SOLVED] How to make dynamic link to uploaded file?

I want to make a link to the file just uploaded in a form in Events --> OnSubmit --> Email --> Template.

Using the debug feature, I can see an array like this:

[_PLUGINS_] => Array
(
  [upload_files] => Array
  (
    [file_upload] => Array
    (
      [name] => 20120613083148_readme.txt
      [path] => /home/xxx/htdocs/components/com_chronoforms/uploads/yyy/20120613083148_readme.txt
      [size] => 37
      [link] => http://www.xxx.com/components/com_chron ... readme.txt
    )
  )
)

So I want to use something like {file_upload[link]} as a dynamic field in my email template. But chronoforms interprets this as a literal string, not the result of an array.

What is the correct syntax to achieve the value from the array, or the best way to get this?

Thank you,

Marcelo

Hi Marcelo,

As you see there are a couple more layers to the nested arrays than you have allowed for.

I'd drag in a Custom Code action after the Upload Files action and before the Email action and add this to it

<?php
$link = $form->data[_PLUGINS_][upload_files][file_upload][link];
$link = "<a href='{$link}'>Click to download</a>";
$form->data['link'] = $link;
?>

Then use {link} in your Email template.

PS You can add the PHP in the template if you prefer but I find it helps to keep the code separate.

Hi Greyhead,

Your code worked just perfectly. And you also showed me how to deal with the full path of an array, and where to put the custom code, not messing up the email template.

Thank you very much!

This is very helpful.

My form is currently using two upload fields. How can I create a links to each individual uploads.
Any help will be greatly appreciated.

Thanks,

Hi Todd,

I think that you can just repeat the code there twice for link1 & link2. You'll need to change the file_upload part to match the names of your File inputs.

Bob,

Thanks very much. Your suggestion worked.

Now, is there a way to make it so the links do not show in the email if no files are submitted?

Hi Todd,

Please try:

<?php
$form->data['link'] = '';
if ( isset($form->data[_PLUGINS_][upload_files][file_upload][link) && $form->data[_PLUGINS_][upload_files][file_upload][link != '' ) {
  $link = $form->data[_PLUGINS_][upload_files][file_upload][link];
  $link = "<a href='{$link}'>Click to download</a>";
  $form->data['link'] = $link;
}
?>
