仅当字段中不存在任何值时显示“提交”按钮，否则显示值

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!

<td style='font-size:12px;'><center>{$row['Restoration_Decision_Matrix']}</center></td>

    <form action='".$_SERVER['PHP_SELF']."' method='post'>
    <input type='hidden' id='ID' name='ID' value='{$row['ID']}' />

    </form>
{$row['Call_Attempt_One']}

</tr>";

}

//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."'");
    }
}
