note 54810 added to language.variables.variable

Easy way to get a list of items selected by the user, using checkboxes and variable variables. My form: <? include("mysql.inc.php");//my mysql connection $proSQL = "SELECT * FROM products ORDER BY name"; //selecting products from DB $pro_query = mysql_query($proSQL) or die($proSQL."<br>".mysql_error()); $pro_num = mysql_num_rows($pro_query); //number of products print("<form action='theend.php' method='post'>"); $i=0; while($products = mysql_fetch_object($pro_query)){ $i++; print("<input type='checkbox' name='$i' value='$products->name'> $products->name<br>"); //print a checkbox with the product name } print("<input type='hidden' value='$pro_num' name='products_number'>");//number of products print("<input type='submit'></form>"); ?> theend.php : <? $i=0; while($i < $products_number){ $i++; if($$i){ $message .="$$i<br>"; } } print("$message");//a list of checked products ?> This will give a list of the products selected by the user. I usually use it to send by e-mail with other informations collected from the form. ---- Manual Page -- http://www.php.net/manual/en/language.variables.variable.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54810 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54810&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54810&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54810&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54810&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54810&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54810&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54810&report=yes Search -- http://master.php.net/manage/user-notes.php
