Edit: the session_start() was in the "entire code of initial page," but wasn't showing. I needed another newline.
Edit 2: Showing the output of the raw HTML rather than the displayed page.
I am working on a document conversion site. It takes a one or two page .docx file and converts it to simple html. (Basically replacing newlines with p tags, no html or head tags as it will be displayed in an existing page). For test purposes I'm converting a .docx file with a single word - "one" - in it.
I am storing the converted data as a string in the variable $_SESSSION['doc']. Because of the issues I've been having, I'm also storing a $_SESSION['test'] string.
I do a var_dump($_SESSION) on the initial page and I can see both variables with populated strings.
I do a var_dump($_SESSION) on the following screen, and the $_SESSION['test'] string comes through okay, but the $_SESSION['doc'] is now a 0 length string. I'm not certain what's truncating my 'doc' string.
The relevant variables are $_SESSION['doc'], $_SESSION['test'], and $outputData. I included the entire first page at the end of this post since I suspect $outputData is getting overwritten.
I believe this is the relevant code snippet for the initial page:
<?php $outputData = preg_replace("/.+/", "<p class='converted'>$0</p>", $outputData);
$outputData = preg_replace("/<\/p>
/", "<br /><br /></p>", $outputData); ?>
<?php if(isset($outputData)){$_SESSION['doc'] = $outputData;}else{$_SESSION['doc']="JustATest";} $_SESSION['test'] = "<>()!';!SDFSDFG^%$"; echo "
<div><br /><br />var_dump: " . var_dump($_SESSION) . "</div>"; ?>
Output:
array(2) {
["doc"]=>
string(32) "<p class='converted'>one</p>
"
["test"]=>
string(18) "<>()!';!SDFSDFG^%$"
Relevant code on the follow up page:
<?php if(session_id() == ''){session_start();}
if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly
global $woocommerce;
$woocommerce->show_messages();
?>
<div>session_id: <?php echo session_id(); ?><br />OUTPUT: <?php echo var_dump($_SESSION); ?></div>
<?php do_action( 'woocommerce_before_cart' ); ?>
<form action="<?php echo esc_url( $woocommerce->cart->get_cart_url() ); ?>" method="post">
Output of follow up page:
session_id: jl40cdmbdpd3h40qg3ogmghkp0
OUTPUT: array(2) { ["doc"]=> string(0) "" ["test"]=> string(18) "<>()!';!SDFSDFG^%$" }
EDIT: I wasn't viewing the raw HTML. /me shakes head.
IGNORE: One thing I found strange on the initial page is the single word "one" is showing up as a 32 char string. . . so there seems to be some extraneous white space after the document conversion. . . but it still outputs from the $_SESSION['doc'] variable on the initial screen.
Entire code for the initial page:
<?php if(session_id() == '' ){session_start();}
if(isset($_POST['added']))
{
add_basic_edit( $_POST['id'], $_POST['wc'] );
unset($_POST['added']);
header('Location: http://localhost/cart/');
exit;
}
/* Template Name: Upload Page */ get_header();
/**
* Test code to programmatically add a pricing calculator product to the cart, on
* every page load
*/
function add_basic_edit( $product_id, $num_words ) {
global $wc_measurement_price_calculator;
$product = get_product( $product_id ); // id of my 'word' product
$measurements = $wc_measurement_price_calculator->get_product_measurements( $product );
// get the one measurement
foreach ( $measurements as $measurement ) ;
$measurement->set_value( $num_words ); // the number of words
// add to cart
$wc_measurement_price_calculator->add_to_cart( $product->id, $measurement );
