if I don't put an empty option, & the user don't change it, that means the user choose the wrong option. thats why I want to make sure the user choose the right one and if it is blank, it should says "you have to choose one option from the list"

Maybe I'm confused but with a SELECT, the first option is automatically selected by default, so it's impossible for someone not to choose an option. Am I missing something...? yes..... this is the code for select <select name="list"> <option></option> <option value="car">car</option> <option value="bus">bus</option> <option value="motorbike">motorbike</option> </select> so 1st option is not selected. its still not working > when I tried with this code, it shows me "The page cannot be found" error

if you don't select any thing from the list, why it is not showing any message, like "please choose one from the list"

I tried with this code.... <?php if (trim($_POST['list'])<="" { $error = "Please pick from the list"; else echo "You selected ". " " . $_POST['list'] . ".<br />"; //echo $_POST['list']; } ?> but it shows me nothing. did I make any mistake?

these are in menu bar, when I click on the menu, these 3options will come but I've to select only 1. so how can I validate it if I don't select any or if I select any one of them...

How can I get the value from the select box, where the value is (car, bus, motorbike), should select anyone of them from the list. if not selected it should give an warning... "select the right vehical" please help me..... thanks

hi here is my code for name field which is a text box. it is working if I put any digit or if the field is empty but when I put the symbols like '%$%^&*!' it still takes the value not showing any error. if ((is_numeric($name))||(empty($name))) { echo 'please enter your name<br>'; return; } can anyone please help me... thanks

thanks a lot mate....

hi I have got a form with name, email address and choose the pet from the list (cat or dog). How can I do the form validation with PHP, if anyone put the wrong name or invalid email address and don't choose anything from the pet list? please help me... thanks

thanks for the reply. Just to make it a bit clear. I have got a textbox for name and another one for email address and a select button (value is cat, cow, dog) from where I will select one and validate the user name and email address. so the name field should not contain any digit and the email address should be a valid email address... thanks once again

Hi this is Sha. I don't know how to start. I am going to design a database where there will be two tables, one for log in details and another one will be for student marks. There should be a standard say 40 marks. If any student gets less than 40, and everytime when he/she log in to the system, it will show him/her a message say for example "do more practice" until he/she reach the standard. I have got no clue how to start. Can anyone please help me to how to start? I am sorry if I post this in the wrong forum. Thanks... Sha
