Title case (capitalise) field in repeater

Hi,
I'm using [foreach 13]<tr><td>[15]</td><td>[29]</td></tr>[/foreach] to list values from a repeater in a pdf.
I want the first letter of [15] to be capitalised.
I tried [e2pdf-format-output filter="strtoupper"][15][/e2pdf-format-output] but this broke the repeater arrangement and I ended up with value, value, value.
I tried <span style="text-transform:capitalize;">[15]</span> but no effect.
Please could you advise how I should go about this?
Thanks,
Phil.

Hi,

Unfrotunately yes, [e2pdf-format-output] shortcode wrapper will not working inside repeater section. You can try to wrap needed value with some "span" tag with "class" and add custom filter to your functions.php

For example:
[foreach 13]<tr><td><span class="upper">[15]</span></td><td>[29]</td></tr>[/foreach]

Add function to functions.php: https://codeshare.io/ayBYvz

* Replace inside function:
$e2pdf_template_id to your Template ID
$e2pdf_element_id to your E2Pdf Element ID. It can be found via "Right Mouse Click" -> "Properties" (Element ID) (screenshot attached).

Let us know please if such solution will work for you. Thank you.

We remain at your service.

Thanks so much for getting back to me so quickly!
I have created the function you wrote and added the <span class="upper"> into the template. But no change.

I don't see where the function defines the class "upper". Is something missing from the above?
Thanks,
Phil.

Did you copied the function to your functions.php with changed $e2pdf_template_id and $e2pdf_element_id ? https://codeshare.io/ayBYvz. This added function must replace data via preg_replace_callback search values with class "upper".

add_filter('e2pdf_extension_render_shortcodes_value', 'e2pdf_extension_render_shortcodes_value_uppercase', 10, 5);
function e2pdf_extension_render_shortcodes_value_uppercase($value, $element_id, $template_id, $item, $dataset) {
$e2pdf_template_id = '11'; //Template ID
$e2pdf_element_id = '1'; //Element ID

if ($template_id == $e2pdf_template_id && $element_id == $e2pdf_element_id && $value) {
$value = preg_replace_callback('/(<span class="upper">)(.*?)(<\/span>)/', function ($matches) {
return ucfirst($matches[2]);
}, $value);
}

return $value;
}

Thanks.
Yes all copied and set up the template id and element id. The problem seems to come when I add <span "upper"> and </span> into the element. When the e-mail is sent, I just get html at the receipient instead of the formatted e-mail. If I remove those tags, it's ok.
Any further thoughts?
Cheers,
Phil.

<span class="upper"> must not affect actually email functionality, filter must fire only inside generated PDF, however, can you please attach some screenshots of modified "E2Pdf" element value. with <span class="upper"> , screenshot of Element ID and screenshot of inserted function to functions.php? Also screenshot of result of broken email.

P.S. You can mark message "private" so only you and support can see message.

Sorted!
I think it was the SMTP client I was using. Changed it and OK.
Many thanks for your help.

If I want to use it for another element, do I need to add a new version of the code or can I chain element ids?

Here is an updated function with example of multiple template with multiple elements usage: https://codeshare.io/ayBYlq

There is array which with "key" of E2Pdf Template ID and "sub" array with Element IDs so you can use just 1 function for all needed templates and elements by adding needed values to it.
