Question

I’m designing a user preferences webpage and now I’ve placed two save buttons, one to save a new changed password, and other to save other kind of user preferences. My doubt is that I’m not sure if this is the more accessible and usable way to implement it.
I would hear opinions about what is the best option and why, because I haven’t found any clear direction about this issue in the web.

Ok so if you’ve got a form like so:

<form action="YOUR_PAGE" method="POST">

    <label>Field 1: </label><input type="text" name="form_field_1" />
    <label>Field 2: </label><input type="text" name="form_field_2" />

    <input type="submit" name="submitFieldOneOnly" value="Submit field 1" />
    <input type="submit" name="submitFieldTwoOnly" value="Submit field 2" />
</form>

You need to run different code depending on which button was pressed you can use the following PHP code on the page your form submits to:

<?php
    if (isset($_POST['submitFieldOneOnly'])) {
        //Submit button one was pressed
        echo $_POST['form_field_1'];
    }

    if (isset($_POST['submitFieldTwoOnly'])) {
        //Submit button two was pressed
        echo $_POST['form_field_2'];
    }
?>

This should be more than enough to do what you’re after.
