note 99124 added to function.filter-input

Note that this function doesn't (or at least doesn't seem to) actually filter based on the current values of $_GET etc. Instead, it seems to filter based off the original values. <?php $_GET['search'] = 'foo'; // This has no effect on the filter_input $search_html = filter_input(INPUT_GET, 'search', FILTER_SANITIZE_SPECIAL_CHARS); $search_url = filter_input(INPUT_GET, 'search', FILTER_SANITIZE_ENCODED); echo "You have searched for $search_html.\n"; echo "<a href='?search=$search_url'>Search again.</a>"; ?> If you need to set a default input value and filter that, use filter_var on your required input variable instead ---- Server IP: 117.55.229.1 Probable Submitter: 59.167.236.95 ---- Manual Page -- http://www.php.net/manual/en/function.filter-input.php Edit -- https://master.php.net/note/edit/99124 Del: integrated -- https://master.php.net/note/delete/99124/integrated Del: useless -- https://master.php.net/note/delete/99124/useless Del: bad code -- https://master.php.net/note/delete/99124/bad+code Del: spam -- https://master.php.net/note/delete/99124/spam Del: non-english -- https://master.php.net/note/delete/99124/non-english Del: in docs -- https://master.php.net/note/delete/99124/in+docs Del: other reasons-- https://master.php.net/note/delete/99124 Reject -- https://master.php.net/note/reject/99124 Search -- https://master.php.net/manage/user-notes.php
