HTML表单到多个电子邮件

Question

I have a form with 9 text fields where users can input their friends' emails. The recipients will receive HTML email in their inbox.

Question, how do I make it so that the users don't have to input in all the 9 text fields? As for now, when I just enter an email on 1 field, they will display 8 errors (for each unfilled text field)

Your Form fields.

    <input type="text" name="email[]" />
    <input type="text" name="email[]" />
    <input type="text" name="email[]" />
    <input type="text" name="email[]" />
    <input type="text" name="email[]" />
    <input type="text" name="email[]" />
    <input type="text" name="email[]" />
    <input type="text" name="email[]" />
    <input type="text" name="email[]" />

If you remove the nulls your program will not throw any errors. Write this bellow condition in action form.

    <?php
    $AllEmails=$_REQUEST['email'];

    // To remove nulls.
    $emails=array_filter($AllEmails);

    for($itr=0; $itr<count($emails); $itr++)
    {
        echo "Sent the mail to mail_ID: ".$emails[$itr];
    }
    ?>
