Submit Button only when no value present in field otherwise value shows - php

Question

I'm trying to figure out how to make this code snippet display the value or the button but not both. As you'll see there is a button for "Call_Attempt_One". I'm trying to have it only display when there is no value in the field but have the field value displayed when there is a value and have the button disappear.
Suggestions?? Thanks!

//Check to see if delete button is pressed
if(isset($_POST['formDelete']))
{
if(isset($_POST['ID']) && !empty($_POST['ID']))
{
$ID = $_POST['ID'];
$result = mysql_query("DELETE FROM Project_Submissions WHERE ID ='".$ID."'");
}
}

Answer 1

here is the code that I found to work in my question above. I fixed it myself and replaced these lines
if(isset($_POST['formDelete']))
{
if(isset($_POST['ID']) && !empty($_POST['ID']))
{
$deleteID = $_POST['ID'];
$result = mysql_query("DELETE FROM Project_Submissions WHERE ID ='".$deleteID."'");
}
}
