php - How to get a popup box after submitting a form? -


[solved] replied.

i've got php script run after user submited contact form. script shows message in top left corner saying if worked or if encountered problem.

now question is, how can put messages popup box? know there js involved, barely have knowledge of that.

( example: http://www.dylanvanheugten.nl/contact.php)

php

$name = $_post['name']; $email = $_post['email']; $message = $_post['message']; $from = 'from: site contact'; $to = 'info@dylanvanheugten.nl'; $subject = $_post['subject']; $human = $_post['human'];  $body = "from: $name\n e-mail: $email\n message:\n $message";  if ($_post['submit']) {     if ($name != '' && $email != '' && $subject != '' && $message != '') {         if ($human == '12') {                             if (mail ($to, $subject, $body, $from)) {                  echo '<p>uw bericht verzonden.<br/> u krijgt binnen 3 werkdagen een bericht terug.</p>';             } else {                  echo '<p>er iets mis gegaan tijdens het versturen van uw bericht.<br/> probeert u alstublieft nogmaals.</p>';              }          } else if ($_post['submit'] && $human != '12') {             echo '<p>u heeft de spam preventie som foutief beantwoord.</p>';         }     } else {         echo '<p>alstublieft alle velden invullen.</p>';     } }

html

<form method="post" action="contact.php">     <label>naam</label>     <input name="name" placeholder="naam">      <label>email</label>     <input name="email" type="email" placeholder="email">      <label>onderwerp</label>     <input name="subject" placeholder="onderwerp">      <label>bericht</label>     <textarea name="message" placeholder="laat hier ook uw telefoonnummer achter als u telefonisch contact wilt."></textarea>      <label><strong>*spam preventie*</strong><br/>wat 11+1?</label>     <input name="human" placeholder="11 + 1 =">      <input id="submit" name="submit" type="submit" value="verzend">     <label><u>alle velden zijn verplicht.</u></label> </form>

enclose echo <script> tags this.

echo '<script>alert("alstublieft alle velden invullen");<script>';
