how to use multiple if(isset($_POST)) inside php variable-CodePudding

On a page with multiple checkboxes to select products, I would like to send an email with the selected checkboxes.

The following code successfully outputs what I like after clicking the submit button, but on the webpage. I just cannot figure out how to include the results in the email instead.

Here's the html form:

<form action="" method="post">
    <label for="product1"><input type="checkbox"  id="product1" name="product1" value="100">Add to inquiry</label>
    <label for="product2"><input type="checkbox"  id="product2" name="product2" value="50">Add to inquiry</label>
    <label for="product3"><input type="checkbox"  id="product3" name="product3" value="80">Add to inquiry</label>
    <input type="submit" name="submit"  value="Send inquiry">
</form>

This is the PHP code that successfully prints the results on the page:

<?php
    if(isset($_POST['product1'])){
    echo "checked Product Name 1"."<br>";
    }
    if(isset($_POST['product2'])){
        echo "checked Product Name 2"."<br>";
    }
    if(isset($_POST['product3'])){
        echo "checked Product Name 3";
    }
?>

The result (which is perfect for me) is:
checked Product Name 1
checked Product Name 2
checked Product Name 3

Now I'd like to put the result inside the email message instead. Here's the PHP for the email:

<?php 
if(isset($_POST['submit'])){
    $to = "myemailaddress";
    $from = $_POST['email']; // this is the sender's Email address

    $gearselection = ???;

    $subject = "Inquiry";
    $message = $from . "\n\n" . $gearselection;

    $headers = "From:" . $from;
    mail($to,$subject,$message,$headers);
    echo "Your inquiry has been sent.";
    }
?>

And in $gearselection I would like to output the results from the code above.

Can anyone help?

First off, it should be the name attribute that gets the square bracket, not the class and this name attribute should be defined on the input checkbox not the label.

<form action="" method="post">
  <input type="checkbox" name="product[]" id="product1" value="Product 1">
  <label for="product1">Product 1</label>

  <input type="checkbox" name="product[]" id="product2" value="Product 2">
  <label for="product2">Product 2</label>

  <input type="checkbox" name="product[]" id="product3" value="Product 3">
  <label for="product3">Product 3</label>

  <input type="submit" name="submit"  value="Send inquiry">
</form>

And then on the PHP side, you'll get an array of values depending on what's checked off for $_POST['product'] - you can just loop through them to get all of the items that were selected.

if(!empty($_POST['product'])) {
  foreach($_POST['product'] as $p) {
    echo $p;
  }
}

In your email, you could do something like:

if(!empty($_POST['product'])) {
  $gearselection = implode(', ', $_POST['product']);
}
