php - Passing $_SESSION variable between pages -


edit: session_start() in "entire code of initial page," wasn't showing. needed newline.

edit 2: showing output of raw html rather displayed page.

i working on document conversion site. takes 1 or 2 page .docx file , converts simple html. (basically replacing newlines p tags, no html or head tags displayed in existing page). test purposes i'm converting .docx file single word - "one" - in it.

i storing converted data string in variable $_sesssion['doc']. because of issues i've been having, i'm storing $_session['test'] string.

i var_dump($_session) on initial page , can see both variables populated strings.

i var_dump($_session) on following screen, , $_session['test'] string comes through okay, $_session['doc'] 0 length string. i'm not what's truncating 'doc' string.

the relevant variables $_session['doc'], $_session['test'], , $outputdata. included entire first page @ end of post since suspect $outputdata getting overwritten.

i believe relevant code snippet initial page:

<?php $outputdata = preg_replace("/.+/", "<p class='converted'>$0</p>", $outputdata);                               $outputdata = preg_replace("/<\/p>\n\n/", "<br /><br /></p>", $outputdata); ?>                 <?php if(isset($outputdata)){$_session['doc'] = $outputdata;}else{$_session['doc']="justatest";} $_session['test'] = "<>()!';!sdfsdfg^%$"; echo "\n<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 follow 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 page:

session_id: jl40cdmbdpd3h40qg3ogmghkp0 output: array(2) { ["doc"]=> string(0) "" ["test"]=> string(18) "<>()!';!sdfsdfg^%$" }

edit: wasn't viewing raw html. /me shakes head.

ignore: 1 thing found strange on initial page single word "one" showing 32 char string. . . there seems extraneous white space after document conversion. . . still outputs $_session['doc'] variable on initial screen.

entire code 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 programmatically add pricing calculator product 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 'word' product  $measurements = $wc_measurement_price_calculator->get_product_measurements( $product );  // 1 measurement foreach ( $measurements $measurement ) ;  $measurement->set_value( $num_words );  // number of words  // add cart $wc_measurement_price_calculator->add_to_cart( $product->id, $measurement ); /var/www/html/websites/localhost/wordpress/wp-content/themes/avada/upload.php}  if(isset($_post['posted'])) { require_once 'http/request2.php';  class documentconverterclient {     var $url = '';      function convert($inputfile, $outputtype) {         $this->url="http://localhost:8080/jodconverter-sample-webapp-3.0-snapshot/converted/$inputfile.$outputtype";         $request = new http_request2($this->url);         $request->setmethod(http_request2::method_post)             ->setheader('content-type', 'multipart/form-data')             ->addpostparameter('outputformat', $outputtype)             ->setbody($inputdata);         $request->addupload('inputdocument', $inputfile);          return $request->send()->getbody();     } }  $documentconverter = new documentconverterclient();  $inputfile = $_files['inputdocument']['tmp_name']; $outputtype='txt'; $noext=current(explode(".", $_files["inputdocument"]["name"])); $inputtype=end(explode(".", $_files["inputdocument"]["name"])); $outputfile = "data/$noext.$outputtype";  $outputdata = $documentconverter->convert($inputfile, $outputtype); //file_put_contents($outputfile, $outputdata); } ?>  <div class="column_group"><br /><br />     <div style="float:left;width:30%;" class="left_clumn">         <div style="float:left;width:35%">wordcount:</div><div><?php $wc = str_word_count($outputdata); echo $wc;?>         </div>         <div style="float:left;width:35%">price per word:</div><div>$<?php $product_id=get_page_by_title('basic editing', 'object', 'product' ); $product = get_product( $product_id->id ); $ppw = $product->get_price(); echo $ppw;?>         </div>         <div style="float:left;width:35%">total price:</div><div>$<?php echo number_format(($wc * $ppw),2);?>         </div>         <div><br /><br />             <form name="add_to_cart" id="add_to_cart" action="../upload-page/" method="post">                 <input type="hidden" name="added" value="added" />                 <input type="hidden" name="id" value="<?php echo $product_id->id; ?>" />                 <input type="hidden" name="wc" value="<?php echo $wc; ?>" />                 <?php $outputdata = preg_replace("/.+/", "<p class='converted'>$0</p>", $outputdata);                               $outputdata = preg_replace("/<\/p>\n\n/", "<br /><br /></p>", $outputdata); ?>                 <?php if(isset($outputdata)){$_session['doc'] = $outputdata;}else{$_session['doc']="justatest";} $_session['test'] = "<>()!';!sdfsdfg^%$"; echo "\n<div><br /><br />var_dump: " . var_dump($_session) . "</div>"; ?>                 <span class="bluebutton" onclick="document.getelementbyid('add_to_cart').submit()">add cart</span>             </form>         </div> </div>     </div>     <div style="float:right;width:70%;" class="right_column">         <div><?php echo $outputdata; ?></div>     </div> </div>  <div id="content" style="<?php echo $content_css; ?>"> </div> <div id="sidebar" style="<?php echo $sidebar_css; ?>"><?php generated_dynamic_sidebar(); ?></div> <?php get_footer(); unset($_post['posted']); ?>

you must add session_start() top of pages before anything rendered output page.
