how to pass variables around?

stefke

ok, let me try to explain this in two words:

you have searched on our homepage the course you want to follow, for example word

so now you're on page like this url http://www.cmo-mechelen.be/detail.php?id=07 and you see

the details of the course (date, hour, location, price, etc ...)

now I want to follow this course, so I click on subscribe me

next I want to show a page where we repeat the course details and a form people can leave their address, phone number etc ...

how does one do that?

Well, ID =07 means something to the first page. Basically your PHP program should interpret that 07 and output the data for it. Most often, 07 corresponds to a row in a database, whereby your program would fetch information from a database and display it.

Then your program builds the Subscribe Me link, perhaps you should pass the ID along there too. In the subscribe me page, you read the ID and perhaps let the user enter their information. Pass ID along using a hidden form field.

When the user clicks submit, the third PHP script reads that ID and performs an insert to a different table in the database.

Start here, with part one and work your way up:

netmastan

letsay we have a student table as follow

id,sname.description

And data is
1,netmastan,Doing computer science
2,matt,Doing software developent

We just want to display student information by id number. Justing using this url student.php?id=somenumber.

so,student.php has the following code

$result=mysql_query("Select id,sname,description where id=$id",$dbi) ;

$records=mysql_num_rows($result);

if ($records>0) {

list($id,$sname,$description)=mysql_fetch_array($result);

echo " student Id :$id<br>Student Name:$sname<br>Description:$description";

}

else {

echo "Sorry NO records found by Id $id";

}

Now if we use student.php?id=1 , we see detials information of student"netmastan";
