ukweb Posted April 6, 2011 Share Posted April 6, 2011 Hi all Basically, I have a form which when done will calculate a quote for turf for given areas. Basically each time the user specifies an area it goes into an array, and they can add as many as they want, but the problem seems to be once submitted and it arrives back into the program, it isn't decoding so the multidimensional array is lost. What am I doing wrong here? Full code below, thanks in advance Ste <?php // Framework // Get the sections $sections_array = base64_decode(unserialize($_POST['sections'])); // Build the rest of the array foreach ($sections_array as $section) { $sections[] = base64_decode(unserialize($section)); } // Set the initial unit $units = $_POST['units']; // Do the new add if ($_POST['a'] == 'add_section') { // Add the new measure if ((is_numeric($_POST['width'])) && (is_numeric($_POST['length']))) { $sections[] = array('length' => $_POST['length'], 'width' => $_POST['width']); } } // Build the output foreach ($sections as $section) { $output .= '<strong>'.$section['width'].' wide</strong> x <strong>'.$section['length'].' long</strong><br />'; $sections_array = base64_encode(serialize($section)); } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Untitled Document</title> <style type="text/css"> body,td,th { font-family: Verdana, Geneva, sans-serif; font-size: 11px; } body { margin-left: 0px; margin-top: 0px; margin-right: 0px; margin-bottom: 0px; } .wrap { text-align: center; height: 350px; width: 410px; padding: 0 10px; } </style> </head> <body> <div class="wrap"> <h2>Turf Calculator</h2> <p>To begin, enter the width and length of the first area of garden you wish to turf.

btherl Posted April 6, 2011 Share Posted April 6, 2011 This line: $sections_array = base64_encode(serialize($section)); should probably be $sections_array[] = base64_encode(serialize($section)); Give that a go. It would be simpler if you used sessions though, I think. Quote Link to comment Share on other sites More sharing options...
spiderwell Posted April 6, 2011 Share Posted April 6, 2011 i would agree on the sessions thing, array passing in a form seems like extra work to me Quote Link to comment Share on other sites More sharing options...
