NAME
- ns_queryexists - Check for a key in the query data that was part of the HTTP request
SYNOPSIS
- ns_queryexists key
DESCRIPTION
- This command looks in the query data for the specified key. If the key exists, 1 is returned; otherwise 0 is returned. The key is interpreted in a case-insensitive manner.
EXAMPLES
ns_register_proc POST /queryexiststest queryexiststest proc queryexiststest { } { if {ns_queryexists name} { # ...process the form... } else { ns_returnerror 400 "you need to supply your name in the form" } } ;# queryexiststest
NOTES
- Note that despite it's name, ns_queryexists works on POST form data as well as query string data.
