I have a website I built for someone a while ago but i used bad coding techniques. I used a class called display and a class called action each page is a 'display' method, and each action (form submit) is an 'action' class method. it's bad because the page is pretty long therefore it takes time to find the method i was looking for. also, the HTML and PHP are combined so i echo all my HTML within the method. My question is, should i just leave it as it is or i rather just rewrite the whole thing?

yah, but i was reading one article and it said something about big classes or using classes for things they are not meant for which is what i am doing here and i'm just wondering if there's something wrong about it.

I have the index.php page and 2 classes index.php, display.class.php, actions.class.php each function in the display class is the page content while the actions class are the POST actions. therefore in the index.php i have a switch for displaying each page if (isset($_POST['submit1'])) actions_class::submit1(); else if (isset($_POST['submit2'])) actions_class::submit2(); switch ($_GET['view']) { case 'register': display_class::register(); break; case 'users': display_class:users(); break; } is there something bad about programming this way? i like it because it's easy to understand and maintain

i have 2 selections 'select_1' and 'select_2' 'select_2' values are being updated depending on 'select_1' it works fine with firefox but i have a weird problem using IE. it looks fine when i select a value from 'select_1' for the first time, but if i select something else, then i select an option i've already selected, it suddenly won't update 'select_2'. do you have any idea what might cause the problem or i should paste the code?

when uploading a file, i move it into a folder but in order to do that, i have to change folder permission to 'write by others' won't it allow anyone just enter that folder and remove\add any file they want? and what can i do about it?

there are websites giving you details such as number of visits for any domain you supply. how can i get and post that information in my website??

I'm giving the user an option to download an excel report. I'm creating the file on the server and giving the user a link to that file. the problem is, the file name is the user's id. any user can just type the url of someone else's xml file. what other options do i have?

I was looking today for tutorials about installing PEAR it looked pretty complicated but then i came into this page http://www.geeksengine.com/article/install-pear-on-windows.html here it seems like all i have to do is copy paste and then include the packages. so what's the difference between including a pear package or someone else's class? another question i have is about mail. I'm trying to send a mail to multiple receipts. the standard way is just separating the receipts by commas but then when i receive the mail, i can see all the receipts who received the mail and i don't want that information to be displayed. what can i do about it? i was reading that looping in order to send a mail many times is a bad idea.

i have a table of categories and a table of subjects. a subject can be related to more than one category therefore i created a 3rd table: category_subject with the relationship between them. then to select it, i'm doing something like this static function select_subjects_by_cat_id($selection, $current_id) { global $db; $new_arr = array(); $query = $db->sql_query("select $selection from $db->subjects_table join $db->subject_category on $db->subject_category.subj_id = $db->subjects_table.id where $db->subject_category.cat_id = $current_id"); while ($result = $db->sql_fetch_array($query)) { $new_arr[] = $result; } return $new_arr; } it works great but then i have to relate many users to one subject. so again, i have to make another table: user_subjects. my site has many relations therefore i'm ending up with many tables is it fine doing it this way or there's a better solution?
