Powermail: create fields from entries in database - typo3

Question

My problem:
i need a matrix of fields in Powermail:
product_1 - price_1 - number_1
product_2 - price_2 - number_2
product_3 - price_3 - number_3
and so on. No problem to create this fields manually, but i need it derived from a database. The numbers of lines depends on the number of entries in the database.
is there a possibility to create fields "on the fly", perhaps by typoscript or a userfunc?
Thanks!

Answer 1

I would create a new field type an call it (e.g.) productsheet. In the manual there is an example how to do it: https://docs.typo3.org/typo3cms/extensions/powermail/ForDevelopers/AddNewFields/Index.html
Here two example page TSConfig lines for the new field:
# Add new fields
tx_powermail.flexForm.type.addFieldOptions.productsheet = Product Fields
tx_powermail.flexForm.type.addFieldOptions.productsheet.dataType = 1
Here is an example Productsheet.html partial file for this:
{namespace vh=In2code\Powermail\ViewHelpers}
<h2><vh:string.escapeLabels>{field.title}</vh:string.escapeLabels><f:if condition="{field.mandatory}"><span class="mandatory">*</span></f:if></h2>
<table>
<thead>
<tr>
<th scope="col">Menge</th>
<th scope="col">Artikel Nr.</th>
<th scope="col">Bezeichnung</th>
<th scope="col">Preis Fr./m</th>
</tr>
</thead>
<tbody>
<f:for each="{0:1,1:2,2:3,3:4,4:5,5:6,6:7,7:8,8:9,9:10}" as="key">
<tr>
<td>
<f:form.textfield type="number" class="mdl-textfield__input " name="field[{field.marker}][amount_{key}]" value="" />
</td>
<td>
<f:form.textfield class="mdl-textfield__input " name="field[{field.marker}][article_no_{key}]" value="" />
</td>
<td>
<f:form.textfield class="mdl-textfield__input " name="field[{field.marker}][description_{key}]" value="" />
</td>
<td>
<f:form.textfield class="mdl-textfield__input " name="field[{field.marker}][price_{key}]" value="" />
</td>
</tr>
</f:for>
</tbody>
</table>
Next step would be to insert fields - as you wrote - on the fly. So what about inserting an own viewhelper instead of defining a hardcoded array in the
Now you could prefill the fields with value="" by your own.
Hope that helps

You can use the TypoScript field of powermail to generate code from typoscript.
You can also use your own field type like discribed here with page TSConfig:
tx_powermail.flexForm.type.addFieldOptions.new = New Field
# The label could also be written with LLL: to localize the label
# Example to grab a value from locallang.xml or locallang.xlf
#tx_powermail.flexForm.type.addFieldOptions.new = LLL:EXT:ext/Resources/Private/Language/locallang.xlf:label
# Tell powermail that the new fieldtype will transmit anything else then a string (0:string, 1:array, 2:date, 3:file)
# Example for dataType array
#tx_powermail.flexForm.type.addFieldOptions.new.dataType = 1
# The new field is not just a "show some text" field. It's a field where the user can send values and powermail stores the values?
# You can tell powermail that this new field should be exportable in backend module and via CommandController
#tx_powermail.flexForm.type.addFieldOptions.new.export = 1
newis the field identifier. Powermail search by default for a partial with the identifier name e.g. New.html.
Now you can use a ViewHelper to get the data and create the html for the fields.
