I am totally stuck here and found tens of samples on posting to get and set values. What I am trying to do is -
1) Let a user enter a vehicles year model into a textbox in my form (set to post)
2) I then need to get this value to a variable state
$vehicle_year = $_GET['vyear'];
First error is here... vyear is the name and id for my textbox. Error - Undefined index 'vyear'. There is no submission of the form etc, because I am still on the same form/page.
3) With this value captured, I then search my database to return all of the manufacturers that has a year (as returned) attached to it -
$query = "SELECT * FROM `vehicledata` WHERE `year`='$vehicle_year'";
Obviously it does not work because I still do not have the value as yet returned from above with the undefined error. I've tried to change the name and id of the textbox, no luck.
4)Once these records has been returned, I need to add the values to a select (drop down) box. I have no idea how to get the values in there - seems I need to run a loop, which I know how to, just don't know how to add the options to the select box.
Any help will be appreciated, thanx guys.
P.S. I will add against sql injection once I know how to get the values and add the options. Just need the basics to get me going... :)
