Display array field as a list using a template

[telecastg]

I have noticed that when a field type array is set as "displayAsList" it displays fine in detail view but if I add the same field to a template and print to PDF the field shows as a joined string and not as a list.

Same case for a field type Checklist.

Is there a way to actually display an array or checklist field as a list using a template ?

Thanks in advance to anybody who can help.

Hello telecastg,
maybe in espoCRM 5.8... we can define custom helper template .. then return a array and make in template a : {{#each ...}}

else i have another (certainly bad) solution who work :

custom service :

public function loadAdditionalFields(Entity $entity)
        foreach ($row as $i => $v) {            
            $activityDataList[$i] = (object) $v;
        }

and
public function loadAdditionalFieldsForPdf(Entity $entity) 

and in pdf template use {{#each ...}}

i think the goal is return a array of objet of the field

it's just my skill

Regards

Thanks item, I appreciate your response and will give it a try !

By the way I don't believe that there are bad solutions ;-) at least you provided one !

Thanks again

Hi item thanks for pointing me out to the solution, it turned out to be a lot simpler than I thought.

You were right, all I needed to do is to use the {{#each}} loop and render the array field as a list instead of trying to use a simple placeholder as I was doing, although thankfully it wasn't necessary to do any coding.

Here's the template snippet for an array field called materialsPurchased

<ul class="list-group">
  {{#each materialsPurchased}}
    <li class="list-group-item list-row">{{this}}</li>
  {{/each}}
</ul>

I found this out by searching for help with Handlebars which is something on which I am still not proficient at all !

Note: If printing to PDF the list with the code above will be rendered as an un-styled list because of the TCPDF engine limitations.

Alternative styling to display array field making it more compatible with TCPDF

{{#each materialsPurchased}}
<table><tbody><tr><td>{{this}}</td></tr></tbody></table>         
{{/each}}

Regards
