How can I pull a the value entered from an input field on a VF page to the controller?

Here is my Class
global class AdditionalUnitRequest {  
    
    string RecId = apexpages.currentpage().getparameters().get('id');
    
    public string fieldvalue {get;set;}
    public decimal yourNoUnits {get;set;}
    public Opportunity opp {get;set;}
    
    // This gets the finance details related to RecId
         
    list <Finance_Details__c> FinanceDetails;
     global List <Finance_Details__c> getFinanceDetails(){
         FinanceDetails = [SELECT id,Billing_Cycle__c,Account_Name__r.Name,Term__c,Price_Per_Month__c,Contact__r.Name
            FROM Finance_Details__c WHERE Account_Name__c = :RecId AND RecordType.Name = :'Last Order Details' Limit 1];
     return FinanceDetails;
     }
    
    // This is for the picklist options
    
	public string selectedname{get;set;}
    
            
    global list <selectOption> getselectednamefields(){
      list<selectOption> lstnamesel = new list <selectOption>();
            lstnamesel.add(new selectOption('','-- None --'));
            for (Contact con: [SELECT id,name,email FROM Contact WHERE Account.id =: '001D0000026gSLH' AND Allowed_to_Sign__c =: TRUE])
            lstnamesel.add(new selectOption(con.id,con.name));
            return lstnamesel;
        }
    

    // This creates the opportunity with details
    
    public void passValueToController(){
        fieldvalue = selectedname;
        
        string RecId = apexpages.currentpage().getparameters().get('id');        
        string RecType = '012D0000000Bamx';
        string OppType = 'Additional Units';
        string Stage = '02 - Pending';
        string SubStage = 'Finance Proposed';
        string TM = '005D0000001ynPu';
        string OppCur = 'CAD - Canadian Dollar';
        string HowsFunded = 'external Lease (Canada)';
    	String Contact = fieldvalue;
        
        Contact c = [SELECT id, name, email, Account.Name FROM Contact WHERE contact.id =: fieldvalue];
       
        string CompanyName = c.Account.Name;
  
        // Assign values to opp
        opp = New Opportunity();
        opp.Name = CompanyName + ' 1';
        opp.AccountId = RecId;
        opp.Main_Contact_Name__c = Contact;
        opp.StageName = Stage;
        opp.Type = OppType;
        opp.Sub_Stage__c = SubStage;
        opp.CloseDate = system.today() + 31;
        opp.User__c = id.valueOf(TM);
    //opp.TotalOpportunityQuantity = ; ****** I'm wanting to update this field from the VF Page *********
        opp.CurrencyIsoCode = 'CAD';
        opp.How_is_the_order_funded__c = HowsFunded;
        
        
        //Create Opp
        insert opp;
    } 

}

Here is my VF Page: 
 
<apex:page showHeader="false" sidebar="false" Controller="AdditionalUnitRequest" >

<style>
</style>

    
    <apex:dataTable value="{!FinanceDetails}" var="fd" width="700px">
        <apex:column headerValue="Billing Cycle" width="12%">
            <apex:outputText value="{!fd.Billing_Cycle__c}"/> 
        </apex:column>
        <apex:column headerValue="Account Name" width="12%">
            <apex:outputText value="{!fd.Account_Name__r.Name}"/> 
        </apex:column>
        <apex:column headerValue="Term" width="12%">
            <apex:outputText value="{!fd.Term__c}"/> 
        </apex:column>
        <apex:column headerValue="Price Per Month" width="12%">
            <apex:outputText value="{!fd.Price_Per_Month__c}"/> 
        </apex:column>
        <apex:column headerValue="Contact" width="12%">
            <apex:outputText value="{!fd.Contact__r.Name}"/>
        </apex:column>
    
    </apex:dataTable>

<apex:form >
    <span> Contacts: </span>
        <apex:selectList size="1" value="{!selectedname}" onclick="" >
            <apex:selectOptions value="{!selectednamefields}"/>
           <!--   <apex:actionSupport action="{!passValueToController}" reRender="values" event="onchange"/>   -->
        </apex:selectList>
       <apex:inputField value="{!Opp.TotalOpportunityQuantity}" >
       </apex:inputField>
       <!-- <apex:outputText value="{!fieldValue}" label="You have selected:" id="values"/> -->
        <apex:commandButton status="sending" styleClass="buttons" action="{!passValueToController}" title="Order Additionals" value="Order Additionals" oncomplete="Submitted()">
        </apex:commandButton> 
        
</apex:form>



    
</apex:page>

It is the total Opportunity Quantity I'm trying to to map into the the class, I have tried various things but I can't seem to figure it out. I'm sure its something really obvious i'm missing any help would be appreciated. Thanks in advance.

Hi Sam Ward,

I go through your issue, You just have to add your class constructor and reallocate your opportunity object. 

You can use directly this code this will help you.
 
global class AdditionalUnitRequest {  
    
    string RecId = apexpages.currentpage().getparameters().get('id');
    
    public string fieldvalue {get;set;}
    public decimal yourNoUnits {get;set;}
    public Opportunity opp {get;set;}
    
    public AdditionalUnitRequest() { // You have to allocate memory for your opportunity object
        opp = new Opportunity();
    }
    // This gets the finance details related to RecId
    
    list <Finance_Details__c> FinanceDetails;
    global List <Finance_Details__c> getFinanceDetails(){
        FinanceDetails = [SELECT id,Billing_Cycle__c,Account_Name__r.Name,Term__c,Price_Per_Month__c,Contact__r.Name
                          FROM Finance_Details__c WHERE Account_Name__c = :RecId AND RecordType.Name = :'Last Order Details' Limit 1];
        return FinanceDetails;
    }
    
    // This is for the picklist options
    
    public string selectedname{get;set;}
    
    
    global list <selectOption> getselectednamefields(){
        list<selectOption> lstnamesel = new list <selectOption>();
        lstnamesel.add(new selectOption('','-- None --'));
        for (Contact con: [SELECT id,name,email FROM Contact WHERE Account.id =: '001D0000026gSLH' AND Allowed_to_Sign__c =: TRUE])
            lstnamesel.add(new selectOption(con.id,con.name));
        return lstnamesel;
    }
    
    
    // This creates the opportunity with details
    
    public void passValueToController(){
        fieldvalue = selectedname;
        
        string RecId = apexpages.currentpage().getparameters().get('id');        
        string RecType = '012D0000000Bamx';
        string OppType = 'Additional Units';
        string Stage = '02 - Pending';
        string SubStage = 'Finance Proposed';
        string TM = '005D0000001ynPu';
        string OppCur = 'CAD - Canadian Dollar';
        string HowsFunded = 'external Lease (Canada)';
        String Contact = fieldvalue;
        
        Contact c = [SELECT id, name, email, Account.Name FROM Contact WHERE contact.id =: fieldvalue];
        
        string CompanyName = c.Account.Name;
        
        // Assign values to opp
        opp = New Opportunity();
        opp.Name = CompanyName + ' 1';
        opp.AccountId = RecId;
        opp.Main_Contact_Name__c = Contact;
        opp.StageName = Stage;
        opp.Type = OppType;
        opp.Sub_Stage__c = SubStage;
        opp.CloseDate = system.today() + 31;
        opp.User__c = id.valueOf(TM);
        opp.TotalOpportunityQuantity = opp.TotalOpportunityQuantity;  
        opp.CurrencyIsoCode = 'CAD';
        opp.How_is_the_order_funded__c = HowsFunded;
        
        //Create Opp
        insert opp;
    }

Hi Sam,

I have understood your requirement and got an example related to you question.
Please review below the example and apply the changes in your codes accordingly.

Controller--
public class AccountExtension {
  /**
   * The variable that stores the Account details
   *
   * @var Account
   */

  private final Account record;

  /**
   * Contructor. Takes a standard controller variable and assigns it to the record
   *
   * @param ApexPages.StandardController stdController
   */

  public AccountExtension(ApexPages.StandardController stdController) {
    this.record = (Account)stdController.getRecord();
  }
}

VF Page--
<apex:page showHeader="true" sidebar="true" standardController="Account" extensions="AccountExtension">
  <apex:form >
    <apex:pageBlock id="container" title="Account Form">
      <apex:pageBlockButtons>
        <apex:commandButton action="{!Save}" value="Save" reRender="errors" status="loading" />
        <apex:commandButton action="{!Cancel}" value="Cancel" reRender="errors" status="loading" />
        <apex:actionStatus id="loading">
          <apex:facet name="start">
            <img src="/img/loading.gif" />
          </apex:facet>
        </apex:actionStatus>
      </apex:pageBlockButtons>
      <apex:pageBlockSection title="Information">
        <apex:inputField value="{!Account.Name}" />
      </apex:pageBlockSection>
    </apex:pageBlock>
  </apex:form>
</apex:page>

If you want to access posted values in your extension, you can simply reference the record variable. For example, if you created a Save() method that would override the standard Save() method in your extension:
 
public PageReference Save() {
  String accountName = record.Name;
}
Or, as per your markup you're using a method called changeStatus:

public PageReference changeStatus() {
   String accountName = record.Name;
}

Here also I got a link , you can refer this also for more help.

Hi Sam,

You can assign a variable to store the value of your input field in the controller and reference that variable as the value of that input field like this:

<apex:pageBlockSection title="My Content Section" columns="2">
                <apex:inputField value="{!yourInputFieldVariable}"/>
</apex:pageBlockSection>

You controller will look like this:

public class yourController {
  public String yourInputFieldVariable {get;set;}

  public void yourMethod() {
    System.debug('This is your input field value' + yourInputFieldVariable);
  }
}
