#32517 [NEW]: Bug in HTTP_POST_VARS with checkboxes

From: crandym2003 at yahoo dot com Operating system: Windows/Unix PHP version: 4.3.10 PHP Bug Type: CGI related Bug description: Bug in HTTP_POST_VARS with checkboxes Description: ------------ When using HTML checkboxes in an application, the checkbox is not recognized in HTTP_POST_VARS unless it is checked. If the checkbox is checked, the value of "customer_active" is "on", however it the checkbox is not checked, no value exists and HTTP_POST_VARS does not recognize the entity "customer_active". I believe HTTP_POST_VARS should always recognize a defined HTML entity regardless of its state (i.e., checked or unchecked) Reproduce code: --------------- if ($m['customer_active'] == 'yes') {$customer_active = 'CHECKED'; } else { $customer_active = ''; }; print '<form name=EditCustomer action="submit_customer.php" method="post" enctype="multipart/form-data" onsubmit="return CheckForm(this)">'; print '<tr>'; print '<td class=fieldname>Activate Customer:</td>'; print '<td class=formfield><input type="checkbox" name="customer_active" '.$customer_active.' ></td>'; print '</tr>'; print '<TR>'; print '<TD width="20%" height="19"><INPUT class=FormAdmin type="submit" value="Submit" >&nbsp;&nbsp;<button class=FormAdmin type="button" onclick="history.back()">Cancel</button></TD>'; print '<TD width="80%" height="19"></TD>'; print '</TR>'; Expected result: ---------------- If the checkbox is unchecked, the value of "customer_active" should be "off" instead of HTTP_POST_VARS reporting that it is undefined. Actual result: -------------- If the checkbox "customer_active" is checked, then HTTP_POST_VARS['customer_active'] has a value of 'on'. If it is unchecked, there is no defined HTTP_POST_VARS['customer_active']. -- Edit bug report at http://bugs.php.net/?id=32517&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32517&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32517&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32517&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32517&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32517&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32517&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32517&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32517&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32517&r=support Expected behavior: http://bugs.php.net/fix.php?id=32517&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32517&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32517&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32517&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32517&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32517&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32517&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32517&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32517&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32517&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32517&r=mysqlcfg
