How to make multiple submit buttons toggle with PHP

Question

Hello all, My newbie question of the day is....

I have a comment function on my site that I have 3 versions of for the same page. I have one that has specific traits for A. signed in and looking at own profile B. signed in looking at someone elses profile C. Not signed in at all

I have it working just great depending on what criteria the user falls under. I have a submit button that sends one of these formats, so my question is, how do I toggle (in this case two,because C. does not require a button) two different buttons for the same if(isset chunk?

Here is what I am wanting to add onto/alter:

if(isset($_POST['commentProfileSubmit']) && $auth) {

Answer 1

Do you mean you have two (or more) submit buttons for the same form? Give each button unique name:

<input type="submit" value="Button A" name="button_a" />
<input type="submit" value="Button B" name="button_b" />

And in php check the POST value:

if(isset($_POST['button_a'])){
    echo 'Button A clicked';
}else if(isset($_POST['button_b'])){
    echo 'Button B clicked';
}

If I understood your question correctly...

Not sure if this is what you need, but:

in the html markup, use something like

<input type="submit" name="commentProfileSubmit" value="<?= $pageVersion ?>" />

, $pageVersion stand for the variable/value you use to determine your page version.

Then in php, you have

if (isset($_POST['commentProfileSubmit'])) {
switch ($_POST['commentProfileSubmit']) {
case 'A':
    echo 'from A';
    break;

case 'B':
    echo 'from B';
    break;
}
