DOMPDF of a full dynamic PHP page
E. N. Vickery
I'm trying to utilize DOMPDF to generate a PDF from a dynamic php page (a table filled with values from a POST form on a previous page).
I'm following the solution described here: Making download link to DOMPDF generated pdf on same page
Following the formula described in that answer, I'm defining the HTML of the page as a variable, then passing it as the value of a hidden form input:
<!--HTML/PHP of page here-->
Here's some awesome dynamic page content filled with POST form values.
<!--end HTML/PHP of page-->
<form id="hidden_form" name="" action="dompdftest.php" method="POST">
<input type="hidden" id="html" name="html" value=""/>
<input type="submit" id="submitlink" name="submit"/>
</form>
<!--load jquery-->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<!--when click submit_link button, assign #hidden_form_input value of page html-->
<script>
$(document).ready(function() {
$('#submitlink').click(function() {
var html = $("body").html();
$('#html').val($html);
$('#hidden_form').submit();
});
});
</script>And here's the next page, dompdftest.php, which should be loading a DOMPDF PDF:
<?php
require_once("./dompdf/dompdf_config.inc.php");
if ( isset( $_POST["html"] ) ) {
$_POST["html"] = stripslashes($_POST["html"]);
$dompdf = new DOMPDF();
$dompdf->load_html($_POST["html"]);
$dompdf->set_paper($_POST["paper"], $_POST["orientation"]);
$dompdf->render();
$dompdf->stream("dompdf_out.pdf", array("Attachment" => false));
}
?>If I test by assigning a value to the hidden input, i.e.
<script>
$(document).ready(function() {
$('#submitlink').click(function() {
var html = $("body").html();
$('#html').val('Hello');
$('#hidden_form').submit();
});
});
</script>...it works fine - prints a PDF with "Hello". Why isn't it working when try to pass the HTML as a variable? Do I need to pass the POST values from the dynamic page again? If so, how do I do that?
Thanks in advance for any help on this challenge! Can also be answered on SO http://stackoverflow.com/questions/28254906/submit-full-html-of-page-w-hidden-form-dompdf-of-dynamic-php-page
