Two Functions:ReadFormVariables and SendHiddenFormFields

<%
'===================================================
'The Functions below were developed by Robert Collyer:- ASPwiz@hotmail.com
'
'These scripts will now make variables live well beyond the page scope and make the debugging
'process of passing variables between pages just a memory.
'All scripts are really flexible and work on form elements, querystrings and cookies.
'
'====================================================
'The first Funtion-'GetVariables(type1, type2)' can be used in place of the very common:-
'var1=request.form("var1")
'var2=request.form("var2")
'var3=request.form("var3")
'var4=request.form("var4")
'var5=request.form("var5")
'and likewise for reading in querystrings and cookies
'
'Taking FORMS as an example:
'You simply now just call the function, and all vbscript values are set to match those
'posted from a form. This sounds great, and it is but the vbscript variables are named
'identically to the form/querystring/cookie variable names (this is usually a good thing)
'If for example a form contained a text box that is named 'Surname',
'and after submitting the form, the following page called upon the 'GetVariables("form",0)'
'function, VBScript would now have access to a variable called Surname containing the value
'of whatever the user entered into the textbox. It will loop through ALL form variables,
'setting the VBScript equivelents.
'
'
'===================================================
'The Second Function-'SaveAsFormFields(type1, type2)' is very useful for those occasions where
'you need to read in all the form/querystring/cookie values, and include them within another form as
'hidden fields. Reasons to this could include multiple page forms and also when a user
'enters data incorrectly on a form, and you want to post the data back for editing, etc
'
'===================================================
'The Third Function-'SaveAsCookie(type1, type2) will pass the variables stated by type1 and type2
'to a cookie on the clients computer. You can retrieve this cookie and read the variables
'back in on another page using:- Call GetVariables("cookies",0)

'=====================================================

'I do not require a mention if you use this code (Unless the source is published), it
'is supplied purely because
'I know how much of a pain in the arse the long way round is and I feel sorry for those
'who are non-the-wiser. Please feel free to distribute this as far and as wide as you like.

'==================================================    
' Call the following function with:
'
' Call GetVariables("TYPE1", "TYPE2") replacing TYPE1 and TYPE2 with: form, cookies or querystring.
'
' Alternatively the function may be called as follows:
' Call GetVariables("ALL", 0) calling the function in this way performs all three types.
'====================================================
    function GetVariables(type1,type2)

                Execute(TheString)'Executes the command contained in the string(This will set all VBScript variables)
            Next
