I have to pass quantity and  price of product with commandbutton which is out of pageBlockTable.
<center> <!--------------category selection result-------------->
              <apex:pageBlock rendered="{!showpageblocktable}" >
              <center>
              <apex:pageBlockTable value="{!selectedProWrapper}" var="p" >
             
             <apex:column style="width:25%">
                    <apex:inputCheckBox value="{!p.selected}"/>
               </apex:column>
               
               <apex:column style="width:25%" headerValue="Product Name">
               <apex:outputLink title="View Product Detail" onclick="return openPopUp('{!p.Eprod.id}') ">
               {!p.Eprod.name}
               </apex:outputLink>
               </apex:column>
               
              <apex:column headerValue=" Image">
                <apex:outputText value="{!p.Eprod.Image__c}" escape="false" />
              </apex:column>
             
               <apex:column value="{!p.Eprod.Price__c}"/>
               
               <apex:column value="{!p.Eprod.Quantity__c}"/>
               
               <apex:Column style="width:25%">
               <apex:commandLink value="Add to Bucket" action="{!AddToCartButton}" >
               <apex:param name="PQuantity" value="{!p.Eprod.Quantity__c}"/>
               <apex:param name="price" value="{!p.Eprod.Price__c}"/> 
               <apex:param name="PId" value="{!p.Eprod.Id}"/>
               </apex:commandLink>
               </apex:column>
                             
              </apex:pageBlockTable>
              </center>
              <!--@@@@@@@@@@ here i have to pass quantity and price @@@@@@------->
              <apex:commandButton value="Add All to Bucket" action="{!AddToCartButton}" >
              <apex:param name="PQuantity" value="{!p.Eprod.Quantity__c}"/>
               <apex:param name="price" value="{!p.Eprod.Price__c}"/> 
               <apex:param name="PId" value="{!p.Eprod.Id}"/>
              </apex:commandButton>
              </apex:pageBlock>
              </center>
                              
    </apex:form>
</apex:page>

but i am getting error:
Error: Unknown property 'Landing_Page_Controller.p'    becoz this commandButton is outside of pageBlockTable and 'P' is variable of pageBlockTable. so how i can do this?

No need to send each value to controller when you already having the item in controller under instanse --selectedProWrapper.
just check the value - selected is true or false, wherever it is true take all those record and perform the next action.

please revert in-case of any thing more..:)

   <!---------------commandButton is in pageBlock------------------------------->
   <apex:commandButton value="Place Order for All Products" action="{!placeOrderForAllPro}"/>
  </apex:pageBlock>
  </center>
  
  <apex:commandLink value="View Order" action="{!openOrderPage}"/>
  <apex:commandLink value="Previous Page" style="float:right;" action="{!redirect}"/>
