Question

I have a form with fields that are generated dynamically via a loop.
It’s a pair of fields: name/email. Loop generates two input fields for each value. There’s always an email, while name sometimes can be blank.

<div>
    <input type="text" name="name['.$i.']" value="'.$output['0'].'">
    <input type="text" name="email['.$i.']" value="'.$output['1'].'"> 
</div>

I understand that $_POST will generate an array, something like this:

Array ( [name] => Array ( [1] => Fname Lname [2] => ) [email] => Array ( [1] => [e-mail] [2] => [e-mail] ) ) 

Once I submit this form how do I get the values into my db table? Having difficulty visualizing this loop with two fields…

Having difficulty visualizing this loop with two fields

You have to choose one of the fields as a reference for the loop:

$names = $_POST['name'];
foreach($names as $key=>$name) {
    // $name is already defined. Define further fields based on $key
    $email = $_POST['email'][$key];
    // DB logic goes here. Do not forget to sanitize your inputs!
}
