note 63295 added to language.variables.external

Regarding image input buttons, above where it says: "When the user clicks somewhere on the image, the accompanying form will be transmitted to the server with two *additional* variables, sub_x and sub_y. These contain the coordinates of the user click within the image." This is the case with Firefox (and probably other standards browsers), however my experience with Internet Explorer is that when image inputs are clicked, they only submit the location of the click on the button and *not* the name of the input. So if you have a form to move/delete entries like this entry[] [delete_0] [up_0] [down_0] entry[] [delete_1] [up_1] [down_1] entry[] [delete_2] [up_2] [down_2] Then submitting the form in firefox will give you post variables such as <?php $_POST['delete_2']; // "Delete" - button value $_POST['delete_2_x']; // 23 - x coord $_POST['delete_2_y']; // 3 - y coord ?> In IE you only get <?php $_POST['delete_2_x']; // 23 - x coord $_POST['delete_2_y']; // 3 - y coord ?> So if you are checking for what button was clicked do something like this <?php for ($i = 0; $i < count($_POST['entry']); $i++) { if (isset($_POST['delete_' . $i . '_x'])) { // do delete } } ?> ---- Server IP: 216.194.113.175 Probable Submitter: 86.140.200.54 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/language.variables.external.php Edit -- http://master.php.net/note/edit/63295 Del: integrated -- http://master.php.net/note/delete/63295/integrated Del: useless -- http://master.php.net/note/delete/63295/useless Del: bad code -- http://master.php.net/note/delete/63295/bad+code Del: spam -- http://master.php.net/note/delete/63295/spam Del: non-english -- http://master.php.net/note/delete/63295/non-english Del: in docs -- http://master.php.net/note/delete/63295/in+docs Del: other reasons-- http://master.php.net/note/delete/63295 Reject -- http://master.php.net/note/reject/63295 Search -- http://master.php.net/manage/user-notes.php
