The following is a working draft in progress for an introductory guide to AOLserver and Tcl.
ADP Pages
Hello <Yourname> - Simple page, user submits form, displays name
ADP example
hello-world.adp:
<% set name [ns_queryget name "world"] %> <html> <head> <title>Hello <%= [ns_quotehtml $name] %>!</title> </head> <body> <p>Hello <%= [ns_quotehtml $name] %>!</p> <form> <p>Name: <input name="name" value="<%= [ns_quotehtml $name] %>"></p> <p><input type="submit" value="Go"></p> </form> </body> </html>
Tcl example
hello-world.tcl:
set name [ns_queryget name "world"]
ns_return 200 text/html "<html>
<head>
<title>Hello [ns_quotehtml $name]!</title>
</head>
<body>
<p>Hello [ns_quotehtml $name]!</p>
<form>
<p>Name: <input name="name" value="[ns_quotehtml $name]"></p>
<p><input type="submit" value="Go"></p>
</form>
</body>
</html>"
