相同的形式，不同的行为

Question

So I am using the exact same contact form on two different websites but they act very differently. In the one website, the success/error message loads on the same page (it replaces the of the form and applies the css to make it look nice. On the second website, it opens a new window, no css is applied. I cannot figure out why two forms, exactly the same, act so differently. I have not applied any css to the form on the second site that opens in a new window but do not think that should be causing any major issues.

I have tried hard-coding a target=_self command, replacing the entire code blocks and numerous other hacks/fixes but nothing solves the problem.

The forms HTML:

    <fieldset>
                <div id="form_wrapper">
                <div id="form_left">
                <p><label for="name" accesskey="U"><span class="required"></span>    </label>
                <input name="name" type="text" id="name" value="" placeholder="Name"/>    </p>
                <p><label for="email" accesskey="E"><span class="required"></span>    </label>
                <input name="email" type="text" id="email" value=""  placeholder="Email"/></p>
                <p><label for="phone" accesskey="P"><span class="optional"></span>    </label>
                <input name="phone" type="text" id="phone" value=""  placeholder="Phone (optional)"/></p>
                </div>

                <div id="form_right">
                <p><label for="comments" accesskey="C"><span class="required"></span></label>
                <textarea name="comments" id="comments" placeholder="Type message here..."></textarea></p> 

                <div id="spam">
                <div id="spam_2">
                <label for="verify" accesskey="V"><img src="/image.php" alt="" /></label>
                <input name="verify" type="text" id="verify" placeholder="Enter Characters"/></div>
                <input type="submit" class="submit" id="submit" value="Send" />
                </div>
                </div>
                </div>
                </fieldset>

The form.php in the action (I have removed an if statement that checks spam validation, check the last code block):

<?php session_start();

if(!$_POST) exit;

if (!defined("PHP_EOL")) define("PHP_EOL", "\r\n");

The pieces I removed between the two pages:

    if(trim($phone) == '') {
        $error .= '<li>Your phone number is required.</li>';
    } elseif(!is_numeric($phone)) {
        $error .= '<li>Your phone number can only contain digits.</li>';
    }



    if($session_verify != $posted_verify) {
        $error .= '<li>The verification code you entered is incorrect.</li>';
    }
