TYPO3扩展名输入表单无法保存对象

Question

I am currently developing an extension where I want to create a new object ( request ) which contains a reference (UID) to a second object ( bike ). Simply put, I want to submit a contact form that references the corresponding product.

It is already possible to create a request object in the backend.

But when I try to submit the frontend contact form, I get the following error:

#1298012500: Required argument "bike" is not set.

Here an excerpt from the input form ( New.html ):

<f:form id="request" class="Tx-Formhandler col col-2" action="create" name="newRequest" object="{newRequest}">

            <div class="content">

                <f:form.hidden property="bike" value="{bike.uid}"/>

                <div class="row"> 
                    <div class="col c3">
                        <label for="salutation"><f:translate key="tx_chiliusedbikes_domain_model_request.salutation" />:</label>
                    </div>
                    <div class="input col c9">
                        <f:form.select property="salutation" options="{Herr: 'Herr', Frau: 'Frau'}" />
                    </div>
                </div>
                <div class="row required">
                    <div class="col c3">
                        <label for="firstname"><f:translate key="tx_chiliusedbikes_domain_model_request.firstname" />: *</label>
                    </div>
                    <div class="input col c9">
                        <f:form.textfield property="firstname" class="required" />
                    </div>
                </div>

The UID of the bike is correctly passed into the form. But still, the error states that the property is not set. What could be the reason?

Answer 1

Seemingly, the problem was caused by the missing attribute controller of the form. Now it works flawlessly:

<f:form id="request" class="Tx-Formhandler col col-2" action="create" name="newRequest" object="{newRequest}" controller="Request">
