Keeping Query Params in a Hashtable

Demonstrates how to use a Chilkat Hashtable to hold query params and re-emit as a query param string.

Note: The ToQueryString method was added in Chilkat v9.5.0.92.

llSuccess = .F.

loHt = createobject("CkHashtable")

// Add name/value pairs from an existing query param string where the values are already URL encoded.
lcQp = "txt=this%20is%20a%20test&color=blue&fruits=apples%26oranges"
llSuccess = loHt.AddQueryParams(lcQp)

// Add some additional name/value pairs.
loHt.AddStr("name","Jack Sparrow")
loHt.AddStr("movie","Pirates of the Carribean")

// Iterate over the hash table to show what we have..

loKeys = createobject("CkStringTable")
loHt.GetKeys(loKeys)
lnNumKeys = loKeys.Count

i = 0
do while i < lnNumKeys
    lcKey = loKeys.StringAt(i)
    lcVal = loHt.LookupStr(lcKey)
    ? lcKey + " = " + lcVal
    i = i + 1
enddo

// Output for the above loop:

// color = blue
// name = Jack Sparrow
// fruits = apples&oranges
// txt = this is a test
// movie = Pirates of the Carribean

// Get all name/value pairs as a query parm string with values URL encoded
lcQp = loHt.ToQueryString()
? lcQp

// Result:
// color=blue&name=Jack%20Sparrow&fruits=apples%26oranges&txt=this%20is%20a%20test&movie=Pirates%20of%20the%20Carribean
