Bind the value of hidden field with a property on controller

 

<apex:hidden value="{!hiddenValue}" />

 

 

public Controller() {

  

   public string hiddenValue {get;set;}

}

Thanks Sham, Issue resolved.

 

Here goes the precise code:

 

<apex:page controller="TestControllerDev" showHeader="false" id="testC"> 
	<apex:form id="pixelReqForm">        
	        <apex:inputHidden id="txtURL" value="{!hiddenField}"/>
	</apex:form>        
</apex:page>

Controller:
------------
public class TestControllerDev
{
    private String hiddenField = 'TestValue';
    public String getHiddenField() 
    { 
        return hiddenField; 
    }
    
    public void setHiddenField(String data) 
    { 
        hiddenField = data; 
    }
}

Is "hiddenField" in your apex:inputHidden a dummy reference to a field on your custom object?

I've added the following line to my visualforce page, and now am trying to work out your controller code to work for my use case (I want the Invoice_Internal_Id__c to populate a return URL on a save action.

<apex:inputHidden id="inv" value="{!Invoice__c.Invoice_Internal_ID__c}" />

I realize how old this is, but if anyone can answer I would be appreciative.  I have added the following to my controller APEX and receive the error:
Formula Expression is required on the action attributes. 
 

private String inv = 'a3O1D000000Ct9B';
    public String getinv() {
    return inv;
    }
    
    public void setinv(String data){
    inv = data; }

    public PageReference saveAndfinito(){
    scMain.save();
    PageReference Invoice = new PageReference('apex/newInvoicefromWOwithinvoiceline?id=' + inv);
    return Invoice;
        
    }
