Hi,

Give it a try with <apex:param> to send value to controller from VF page with the help of command link

Hi SFDC Sagarika,

You can use apex:actionFunction to pass the variable and call the function that is written in a controller.

<apex:commandButton value="Place Order for All Products" action="{!placeOrderForAllPro}"/>

In above you can call the apex:actionFunction using onClick on the CommandButton.

Go through the below link to know more.

Hi Force.platform,

Use <apex:param> to pass value using <apex:actionFunction>.

Example - 

Visualforce Page-
  
<apex:page controller="passparam">
 <apex:form>
  <apex:pageblock id="pgblck">
   First name : <apex:inputtext id="fn" value="{!firstname}">
   Last Name :<apex:inputtext id="ln" value="{!lastname}">
 Click this to See full name :  <apex:inputcheckbox onclick="calculate('{!$Component.fn}','{!$Component.ln}')">
Full Name:    <apex:outputtext value="{!fullname}"></apex:outputtext>
  </apex:inputcheckbox></apex:inputtext></apex:inputtext></apex:pageblock>

<apex:actionfunction action="{!calpercentage}" name="calAF" rerender="pgblck">
<apex:param assignto="{!firstname}" name="param1" value="" />
<apex:param assignto="{!lastname}" name="param" value="" />
</apex:actionfunction>
 </apex:form>
 
<script>
  function calculate(frst,lst){
  var Fname = document.getElementById(frst).value;
 var Lname = document.getElementById(lst).value;
   var res = confirm('Do you want to calculate?');
   if(res == true)
      calAF(Fname,Lname );
  }
 </script>
</apex:page>

Controller - 
  
Public class passparam{
Public string firstname{get;set;}
Public string lastname{get;set;}
Public string fullname{get;set;}
 Public void calpercentage(){
  fullname = firstname +' '+lastname;
 }
}

In the Above example, I am using <apex:param> to send the value to the controller.

Kindly mark this as solved if it's resolved so that it gets removed from the unanswered queue which results in helping others who are encountering a similar issue.
