Convert data in TYPO3 fluid form - typo3

Question

I need yours help. I have follow form:
{namespace femanager=In2code\Femanager\ViewHelpers}
<div class="femanager_fieldset femanager_membershipend control-group">
<label for="femanager_field_membershipend" class="control-label">
<f:translate key="tx_feusersplus_domain_model_user.membershipend" default="Expiration date of the membership"/>
</label>
<div class="controls">
<femanager:form.textfield
disabled="true"
id="femanager_field_membershipend"
property="membershipend"
class="input-block-level"
additionalAttributes="{femanager:Validation.FormValidationData(settings:settings,fieldName:'membershipend')}"
/>
</div>
</div>
And it get date in the next format - 1493942400. How I can make good look for date ? Thank you for advice!

Answer 1

Your property seems to be declared as integer (unix timestamp) in the model.
You can change the field to the following:
<femanager:form.textfield
disabled="true"
id="femanager_field_membershipend"
property="membershipend"
class="input-block-level" value="{yourModel.membershipend-> f:format.date(format: 'd.m.Y')}"
additionalAttributes="{femanager:Validation.FormValidationData(settings:settings,fieldName:'membershipend')}"
/>
This will format the property to a readable Date. But after that you will get problems saving the property correctly. If the property is really an integer, you need to write a converter for converting the date to an unix timestamp. It must work like here just in the reverse and I think TYPO3 does not have the correct converter for your needs out of the box.
I recommend you to change your property to DateTime (including the database field). Then you can use the DateTimeConverter of TYPO3 to save the data correctly.
EDIT: In your case the field is disabled="true" which should mean that the data will not become submitted. In that case you should not get problems with converting after submitting the form.
