Call php code on button

Question

I would like to know how to call a php code on a button that triggers an iframe, and this code should be opened in iframe.

Answer 1

To call a PHP code after clicking this button, use an AJAX request for the desired PHP file.

If the code should be executed in iframe, then use the src for the PHP file or integrate it to the page you need. If you need to pass some variable through the URL, just do it through the src and capture the information by $_GET in PHP.

Answer 2

You can activate iframe and set its src dynamically as in this jsfiddle I just did: http://jsfiddle.net/Te7ps/

Answer 3

Well, without too much ado:

<?php
if (!empty($_GET['act'])) {
  echo "Olá, Stack Overflow!"; //Seu código vai aqui, enfim...
} else {
?>
(.. html ..)
<form action="index.php" method="get">
  <input type="hidden" name="act" value="run">
  <input type="submit" value="Clique aqui!">
</form>
<?php
}
?>
