Hi,
I have created a visual force page called "Create Quote" which gathers data from quote line items and creates a PDF page. I have created a button called "Create Quote" which works fine. I need to add the code so when this button is used, it can create a new attachment under attachments automatically. Can someone help me with this code?
The existing code looks like this.

<apex:page standardController="HPL_Pricing__c" renderAs="pdf" applyBodyTag="false">
<div class="header">
    <center><img src="{!$Resource.Logo}" width="25%"/></center>
    <center>P / N</center>
            </div>
  <apex:pageBlock title="HPL QUOTE REQUEST - {!HPL_Pricing__c.Name}">
Customer Account# <b><u>{!HPL_Pricing__c.Account__c}</u></b> <br/>
Customer Name: <u><b>{!HPL_Pricing__c.Distributor_oem__r.Name}</b></u><br/><br/>
Requested Date: <u><b>{!HPL_Pricing__c.Request_Date__c}</b></u><br/>
Project Information: <b>{!HPL_Pricing__c.Project_Information__c}</b><br/>
Request Type: <u><b>{!HPL_Pricing__c.Request_Type__c}</b></u><br/><br/>

</apex:pageBlock>
<apex:pageBlock title="Quote Information">
