Need help printing array

[alexandervj]

Here is my code...

<?php

    $to = "email@email.com"; //obviously not real
    $from = "noreply@domain.com";  //obviously not real
    $firstName = $_REQUEST['firstName'];
    $headers = "From: $from";
    $subject = "Product Sheet Request";

    /*
    $fields = array();
    $fields{"firstName"} = "firstName";
    $fields{"lastName"} = "lastName";
    $fields{"email"} = "email";
    $fields{"phone"} = "phone";
    $fields{"affiliation"} = "affiliation";
    $fields{"interest"} = "interest";
    $fields{"productSheets"} = "productSheets";
    $fields{"referredBy"} = "referredBy";
    $fields{"additional"} = "additional";
    */
    
    $firstName = $_REQUEST['firstName'];
    $lastName = $_REQUEST['lastName'];
    $email = $_REQUEST['email'];
    $phone = $_REQUEST['phone'];
    $affiliation = $_REQUEST['affiliation'];
    $interest = $_REQUEST['interest'];
    if($interest == 'inclusion'){
        $interest = 'Evaluating for inclusion in product';
    } elseif($interest == 'general'){
        $interest = 'Interested in the technology generally';
    } elseif($interest == 'research'){
        $interest = 'Performing market research';
    } elseif($interest == 'solutions'){
        $interest = 'Looking for competitive solutions';
    }
    $referredBy = $_REQUEST['referredBy'];
    $additional = $_REQUEST['additional'];
    $productSheets[] = $_REQUEST['productSheets'];
    $sheets = print_r($productSheets);
    

    /*
    $body = "A user has requested product sheet(s). Please review their information and respond:\n\n"; foreach($fields as $a => $b){   $body .= sprintf("%20s: %s\n",$b,$_REQUEST[$a]); }
    */
    
    $body = "A user has requested product sheet(s). Please review their information and respond:\n
    
    First Name: ".$firstName."\r
    Last Name: ".$lastName."\r
    Email: ".$email."\r
    Phone Number: ".$phone."\r
    Affiliation: ".$affiliation."\r
    Reason for Interest: ".$interest."\r
    Referred By: ".$referredBy."\r
    Additional Questions/Comments: ".$additional."\r
    Product Sheet(s) Requested: ".$sheets."\n
    ";
    
    
    $send = mail($to, $subject, $body, $headers);

?>

I'm not quite sure how to display the values of the $productSheets array in the email message. Everytime it either outputs "Array" or "1". The $productSheets array is from a checkbox on a form. Everything else is working as expected.

The user may have selected multiple values. How would you want, say, 10 values appear? Comma-separated? Bulleted list?

If you can answer that then all you have to do is write the code to support it.

Yeah I just want to know how to display the values in the email instead of "Array" or "1". I tried print_r as seen above but that produced the output "1" instead of the names of the product sheets. Here is the code for my form if that hepls as well...

<form id="contact" name="contact" method="post" novalidate="novalidate">
    <h3>Request Product Sheets</h3>
    <hr style="margin-top:0px; margin-bottom:0px;"/>
    <p>Please fill out the form below and product sheets will be sent to the email provided.<br/>
    * indicates a required field.</p>
    
    <fieldset>
    <table>
	<tr>
	    <td>

Yeah I just want to know how to display the values in the email instead of "Array" or "1".

How do YOU want it to look? You can't tell PHP to make it display a certain way until you can decide what that certain way should be.

[cyberRobot]

Since you're using the array syntax in the HTML form (ex: name="productSheets[]"), PHP automatically creates an array for you. So there is no need for the square brackets when assigning the information to $productSheets. Try changing this:

$productSheets[] = $_REQUEST['productSheets'];

 

To this:

$productSheets = $_REQUEST['productSheets'];

 

 

Now $productSheets can be treated as a regular array. If you want to display the array as a comma-separated list, you could do something like this:

print implode(', ', $productSheets);
