PHP check atleast two buttons are selected

I've a form that will require user to choose/click at least two buttons in order to submit the form

<button type="button" name="Investor-agree-one">I AGREE</button>
<button type="button" name="Investor-agree-two">I AGREE</button>
<button type="button" name="Investor-agree-three">I AGREE</button>
<button type="button" name="Investor-agree-four">I AGREE</button>
<button type="button" name="Investor-agree-five">I AGREE</button>

How do I validate the form using php that at least two buttons are selected and redirect user to one page, if not redirect to another page? So basically is like:

if(buttonSelected>=2){
    goto this page
}else{
    goto another page
    }

How do I indicate whether the button is being selected in the first place using the button elements?

You may use checkbox instead of button, so your code may like this:

<?php
    if(isset($_POST['agree_one'])) {
        // do something
    }
?>
<form method="post">
    <label>
        <input type="checkbox" name="agree_one" value="1"/>
        I Agree
    </label>
    <label>
        <input type="checkbox" name="agree_two" value="1"/>
        I Agree
    </label>
    <label>
        <input type="checkbox" name="agree_three" value="1"/>
        I Agree
    </label>
</form>

But if you just want to count how much user has selected the agree checkbox, you may want this code:

<?php
if(isset($_POST['agree']) && count($_POST['agree']) > 2) {
    // do magic
}
?>
<form method="post">
    <label>
        <input type="checkbox" name="agree[]" value="1"/>
        I Agree
    </label>
    <label>
        <input type="checkbox" name="agree[]" value="1"/>
        I Agree
    </label>
    <label>
        <input type="checkbox" name="agree[]" value="1"/>
        I Agree
    </label>
</form>

Thats pretty easy,

Give your buttons all the same "name", and a unique value so lets say we have this button tag:

<form method="post">
<button name="somebutton" value="buttonone">
<button name="somebutton" value="buttontwo>
<button name="somebutton" value="buttontwo">
</form>

Your php should then look something like this:

<?php
$button = $_POST['somebutton'];
if($button == "buttonone"){
    //do button 1 stuff, in your example:
    header('location: someurl.php');
}
if($button == "buttontwo"){
    // do button 2 stuff
}
?>
