berry05 Posted August 17, 2009 Share Posted August 17, 2009 I have check boxes next to each item when I call up the items from mySQL . How do i make the item disappear in the mySQL database when i user ticks the box and clicks "sell item"? I've been having trouble on that .. <html> <body> <p><a href="index2.php">Index</a> | <a href="shop.php">Shop</a> | <a href="sell.php">Sell</a> | <a href="logout.php">Logout</a> </p> </p> <?php session_start(); $checked = $_POST['checked']; if(isset($_SESSION['otherusername'])){ $db=mysql_connect('localhost', 'root', ''); $res=mysql_select_db('txtgame',$db) or die(mysql_error()); $otherusername = $_SESSION['otherusername']; //"SELECT item FROM users_items WHERE username='".$Username."'"; $res=mysql_query($otherusername)or die(mysql_error()); while($row = mysql_fetch_assoc($res)){ echo ' <input type="checkbox" name="item[]" value="items" />'. ' '.$row['item']."<BR />"; } }else{ echo "Sorry your not a member please join us!"; } ?> <br><input type="submit" value="sellitem"> </form> </body> </html> Thanks !

taquitosensei Posted August 17, 2009 Share Posted August 17, 2009 it will require either onClick posting it or onClick combined with ajax. onClick='this.form.submit();' then checking for the post and doing whatever you need to with the database.

Philip Posted August 17, 2009 Share Posted August 17, 2009 Pretty easy with AJAX - if you want it live (i.e. Click the checkbox and it instantly disappears) But... I think I might have misread your post when I moved it. If you want it when they click the submit button, you need to use a foreach loop to get each checkbox value.... if(isset($_POST['item']) && is_array($_POST['item'])) { // there were some items selected: foreach($_POST['item'] as $item) { // your query string here... } } And the syntax past that is based on how you have your DB setup.

taquitosensei Posted August 17, 2009 Share Posted August 17, 2009 you can't do what you're wanting to do with php only. You have to have some javascript involved.

Philip Posted August 17, 2009 Share Posted August 17, 2009 My apologies for the misunderstanding. It is very possible to do this without ajax - as long as they use a submit button and it isn't a live update (there has to be a fresh page loaded) See my post above for a code example.

taquitosensei Posted August 17, 2009 Share Posted August 17, 2009 I guess I misunderstood I thought he wanted it to happen when they clicked the checkbox.
