hi i am working on the following codes , it will take a value from a query and i want to pass the value of the variable to another php page that will do some statements .

this is my form:

  <form method="post" >    
   <input  type="hidden" name="id" value="<?php echo $orderId; ?>"  />
     <button  type="submit" class="button" name="Reorder" value="Reorder">Reorder </button>
    </form>

Your form doesn't have an action method. According to you, the data is being sent to another page.

action = "validate.php"

And you also didn't check whether the button isset.
