Answer 1

<input type="submit" alt="display" value="display" name="display">';

'<input type="submit" alt="display" value="save" name="save">'; ` 

<?php 

if(isset($_POST['save'])); 

    { 
// from data 
    // insert query 
} 

    if(isset($_POST['display'])); 
    { 
    // post form data and disply 

    } 

    ?>

HTML代码：

<input type="submit" name="save" value="Save" /> 
<input type="submit" name="display" value="Display" /> 

PHP代码：

if(isset($_POST['save'])){ 
    // Your query 
} else if (isset($_POST['display'])){ 
    // Your query 
}
