Hi, 

I would want to get the quantity from the input text of the table. I need it so that I can update the quantity for quote_line_items object.

<apex:page standardController="Product2" extensions="ProductListController">
<apex:form >
    <apex:pageBlock title="Products List">
        <apex:pageBlockSection title="List of Available Address" columns="1">
            <apex:pageBlockTable value="{!productsList}" var="prod"> 
                
                <apex:column headerValue="Select"> 
	    	 		<apex:commandLink value="Select" onclick="return confirm('Are you sure?')" action="{!selectId}" >
		          		<apex:param name="prodid" value="{!prod.id}" />
		          	</apex:commandLink>
		        </apex:column> 
                </apex:column>
                <apex:column headerValue="Product Name" >{!prod.Name}</apex:column>
                <apex:column headerValue="Size/Dimensions" >{!prod.Size_Dimensions__c}</apex:column>
                <apex:column headerValue="Total Quantity" >{!prod.Total_Quantity__c}</apex:column>
                <apex:column headerValue="Available Quantity" >{!prod.Available_quantity__c}</apex:column>
                <apex:column headerValue="Quantity Required" >
                    <apex:inputText value="{!quantity}"></apex:inputText>
                </apex:column>              
            </apex:pageBlockTable>
        </apex:pageBlockSection>    
    </apex:pageBlock>   
</apex:form>
</apex:page>

public with sharing class ProductListController{
    public Product2 product;
    public List<Product2> productsList = null;
    public id quoteId {get; set;}
    public String productId {get; set;}
    public Integer quantity;
    
    public ProductListController(ApexPages.StandardController controller)
    {
        product = (Product2) controller.getRecord();
        quoteId = ApexPages.currentPage().getParameters().get('quoteId');
    }
    
    public Integer getQuantity()
	{
	  return quantity;
	}
	
	public void setQuantity(Integer newTD)
	{
	   quantity=newTD;
	}
    
    public List<Product2> getProductsList()
    {   
        try{
            String query = 'SELECT ID, NAME, Available_quantity__c, Total_Quantity__c,  Size_Dimensions__c FROM Product2 ';
            productsList = Database.query(query);
        }
        catch(Exception e)
        {
            System.debug(e.getMessage());
        }   
        return productsList;
    }
    
    public PageReference selectId(){
    	productId = System.currentPageReference().getParameters().get('prodid');
    	Quote__c quote = [Select id,Name from Quote__c where id=:quoteId];
    	if(productId.length()>15){
			productId = (productId).substring(0,15);	
		}
    	Quote_Line_Item__c quoteLineItem = new Quote_Line_Item__c();    	
    	Product2 product = [Select id, Name from product2 where id=:productId];
    	quoteLineItem.Name = 'PROD - '+quote.Name+'  '+product.Name;
    	quoteLineItem.Product__c =  product.Id;
    	System.debug('*********Quantity*********' + quantity);
    	quoteLineItem.Quantity__c = quantity; 
    	quoteLineItem.Quote__c = quoteId;  	
    	insert quoteLineItem;
    	
    	return new PageReference('/' + quoteId);
    	 
    }
    
}

 But the quantity value does not pass into the variable. Can you please help me out.
