Visualforce Component Saving data

Question

below is my code, I have created an VF Component/VFP/Controller

My question is: How can I save the value of the <apex:inputField in the VF Component

<apex:component>

  <apex:attribute name="fname" description="fn" type="myCustomObject__c" required="true" /> 
  <apex:attribute name="mname" description="mn" type="myCustomObject__c" required="true" /> 
  <apex:attribute name="lname" description="ln" type="myCustomObject__c" required="true" /> 

    <!-- more fields -->
    <apex:inputText value="{!fname.f_name__c}" id="fname"> </apex:inputText>
    <apex:inputText value="{!mname.m_name__c}" id="mname"> </apex:inputText>
    <apex:inputText value="{!lname.l_name__c}" id="lname"> </apex:inputText>

</apex:component>

VF Page:

<apex:page controller="NameInputTextPageController" >

  <apex:form>

  <c:NameInputTextComponent id="vfcom" 
      fname="{!firstname}" mname="{!middlename}" lname="{!lastname}"
  />

    <apex:commandButton action="{!saveme}" value="Save Data" />

  </apex:form>
</apex:page>

VF Page Controller:

public with sharing class NameInputTextPageController {
    public NameInputTextPageController() {}

    public PageReference saveme() {
        return null;
    }
}

A couple things:

• Add allowDml="true" to your <apex:component> tag.
• You only need to pass one instance of your record, not three.
• You can pass an ApexPage.Action and invoke that from your component.

Your markup could probably be simplified to something like:

<apex:page standardController="MyObject__c">
    <apex:form>
        <apex:commandButton value="Save" action="{!save}" />
        <c:nameInputs record="MyObject__c" />
    <apex:form>
</apex:page>

Then your component:

<apex:component allowDml="true">
    <apex:attribute name="record" type="MyObject__c" required="true"
        description="SObject record to edit" />\

    <apex:form>
        <apex:inputField value="{!record.f_name__c}" id="fname" />
        <apex:inputField value="{!record.m_name__c}" id="mname" />
        <apex:inputField value="{!record.l_name__c}" id="lname" />
    </apex:form>
</apex:component>
