"<?"); $Template_IT = preg_replace(... Next, just a simple simple form, have it submit to the same page, no need to even insert it anywhere, the page will show up blank, and if the code had backslashes they will be stripped. Heres what I tried inserting: http://www.acecoolco.com/media_tutorialshow.php?id=28 It inserted fine, stripped the slashes even though it wasnt supposed to, and the resulting page, instead of a thank you page, I got a blank page. I will work on a basic script to show exactly what I mean, it will be in the next reply ------------------------------------------------------------------------ [2003-12-09 17:42:47] eru@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2003-12-09 17:10:12] webmaster at acecoolco dot com Description: ------------ Ive finally traced this bug. If you have a page generated with EVAL Ok, I have a form, when you submit it, it adds code to mysql database, it works, but using EVAL, it removes \s I saw the other bug report saying highlight_string removes the backslashes, this is NOT the case. sites using EVAL, eval removes the backslash, vbb uses eval, it removes the \ on submission. I used to use eval, it removed the backslash on submit. Reproduce code: --------------- $patterns[] = "/{ACWB_DISPLAYPAGELOADTIME}/"; $contents[] = "$DisplayPageLoadTime"; $Template_IT = @preg_replace($patterns, $contents, $string); echo $Template_IT; // I have taken out Eval due to possible security flaws... /* @eval("?>" . $Template_IT . "<?"); */ Expected result: ---------------- Nothing, its just a small snippet Actual result: -------------- . ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26569&edit=1
