ad_include_contract (public)

 ad_include_contract docstring [ args... ]

Define an interface between a page and an ADP <include> similar to the page_contract. This is a light-weight implementation based on the ad_page_contract. It allows one to check the passed arguments (types, optionality) and can be used for setting defaults the usual way. Using ad_include_contracts helps to improve documentation of included content.

Parameters:
docstring (required)
documentation of the include

ad_page_contract (public)

 ad_page_contract [ -form form ] [ -level level ] [ -context context ] \
    [ -warn ] [ -properties properties ] docstring [ args... ]

Specifies the contract between programmer and graphic designer for a page. When called with the magic "documentation-gathering" flag set (to be defined), the proc will record the information about this page, so it can be displayed as documentation. When called during normal page execution, it will validate the query string and set corresponding variables in the caller's environment.

Example:

ad_page_contract  {
        Some documentation.
        @author me (my@email)
        @cvs-id $Id: tcl-documentation-procs.tcl,v 1.66 2024/11/13 08:43:48 gustafn Exp $
    } {
        foo
        bar:integer,notnull,multiple,trim
        {greble:integer {[expr {[lindex $bar 0] + 1}]}}
    } -validate {
        greble_is_in_range -requires {greble:integer} {
            if { $greble < 1 || $greble > 100 } {
                ad_complain
            }
        }
        greble_exists -requires { greble_is_in_range } {
            if { ![info exists ::greble_values($greble)] } {
                ad_complain [_ acs-tcl.lt_Theres_no_greble_with]
            }
        }
    } -errors {
        foo {error message goes here}
        bar:integer,notnull {another error message}
        greble_is_in_range {Greble must be between 1 and 100}
    }
An argspec takes one of two forms, depending on whether there's a default value or not:
  1. {name[:flag,flag,flag] default}
  2. name[:flag,flag,flag]

If no default value is specified, the argument is considered required, but the empty string is permissible unless you specify :notnull. For all arguments, the filter :nohtml is applied by default. If the arg is named *.tmpfile, the tmpfile filter is applied.

Possible flags are:

trim
The value will be string trimmed.
notnull
When set, will barf if the value is the empty string. Checked after processing the trim flag. If not set, the empty string is always considered valid input, and no other filters are processed for that particular value. If it's an array or multiple variable, the filters will still be applied for other values, though.
optional
If there's a default value present, it's considered optional even without the flag. If a default is given, and the argument is present but blank, the default value will be used. Optional and no default value means the variable will not be set, if the argument is not present in the query string.
multiple
If multiple is specified, the var will be set as a list of all the argument values (e.g. arg=val1&arg=val2 will turn into arg=[list val1 val2]). The defaults are filled in from left to right, so it can depend on values of arguments to its left.
array
This syntax maps query variables into Tcl arrays. If you specify customfield:array, then query var customfield.foo will translate into the Tcl array entry $customfield(foo). In other words: whatever comes after the dot is used as the key into the array, or, more mathematically: x.y=z => set x(y) z. If you use dot or comma is part of your key (i.e., y above contains comma or dot), then you can easily split on it in your Tcl code. Remember that you can use any other flag or filter with array.
verify
Will invoke ad_verify_signature to verify the value of the variable, to make sure it's the value that was output by us, and haven't been tampered with. If you use export_vars -form -sign or export_vars -sign to export the variable, use this flag to verify it. To verify a variable named foo, the verify flag looks for a form variable named foo:sig. For a :multiple, it only expects one single signature for the whole list. For :array it also expects one signature only, taken on the [array get] form of the array.
cached
This syntax will check to see if a value is being passed in for this variable. If it is not, it will then look in cache for this variable in the package that this page is located, and get this value if it exists.
date
Pluggable filter, installed by default, that makes sure the array validates as a date. Use this filter with :array to do automatic date filtering. To use it, set up in your HTML form a call to a date formfield. Then on the receiving page, specify the filter using varname:array,date. If the date validates, there will be a variable set in your environment varname with four keys: day, month, year, and date. You can safely pass $varname(date) to Oracle.
time
Pluggable filter, installed by default, that makes sure the array validates as a time in am/pm format. That is that it has two fields: time and ampm that have valid values. Use this filter with :array to do automatic time filtering. To use it, set up in you HTML form using [ec_timeentrywidget varname] or equivalent. Then on the processing page specify the filter using varname:array,time. If the time validates, there will be a variable set in your environment varname with five keys: time, ampm, hours, minutes, and seconds.
time24
Pluggable filter, installed by default, that makes sure the array validates as a time in 24hr format. That is that it has one field: time that has valid values. Use this filter with :array to do automatic time filtering. To use it, set up in you HTML form using <input type="text" name="varname".time>. Then on the processing page specify the filter using varname:array,time24. If the time validates, there will be a variable set in your environment varname with four keys: time, hours, minutes, and seconds.
integer
Pluggable filter, installed by default, that makes sure the value is integer, and removed any leading zeros.
naturalnum
Pluggable filter, installed by default, that makes sure the value is a natural number, i.e. non-decimal numbers >= 0.
oneof
Pluggable filter, installed by default, that makes sure the value X contained in the set of the provided values. Usage example: color:oneof(red|blue|green)
range
Pluggable filter, installed by default, that makes sure the value X is in range [Y, Z]. Usage example: foo:range(1|100)
nohtml
Pluggable filter, installed by default, that disallows any and all html.
html
Pluggable filter, installed by default, that only allows certain, safe allowed tags to pass (see ad_html_security_check). The purpose of screening naughty html is to prevent users from uploading HTML with tags that hijack page formatting or execute malicious code on the users's computer.
allhtml
Pluggable filter, installed by default, that allows any and all html. Use of this filter is not recommended, except for cases when the HTML will not be presented to the user or there is some other reason for overriding the site-wide control over naughty html.
tmpfile
Checks to see if the path and file specified by tmpfile are allowed on this system.
sql_identifier
Pluggable filter, installed by default, that makes sure the value is a valid SQL identifier.
path
Pluggable filter, installed by default, that makes sure that argument contains only Tcl word characters or a few additional safe characters used in paths ("/", ".", "-")
token
Pluggable filter, installed by default, that makes sure that argument contains only Tcl word characters or a few additional safe characters (",", ":", "-").
word
Pluggable filter, installed by default, that makes sure that argument contains only Tcl word characters (as defined by \w in Tcl regular expressions, i.e. characters, digits and underscore).
localurl
Pluggable filter, installed by default, that makes sure that argument contains a non-external url, which can be used in ad_returnredirect without throwing an error.
clock
Pluggable filter, installed by default, that makes sure that argument is a time string formatted according to the format specified in the flag. The format uses the syntax from the clock Tcl command. Usage example time:clock(%H:%M:%S).
more filters...

Note that there can be no spaces between name, colon, flags, commas, etc. The first space encountered denotes the beginning of the default value. Also, variable names can't contain commas, colons or anything Tcl accepts as list element separators (space, tab, newline, possibly others) If more than one value is specified for something that's not a multiple, a complaint will be thrown ("you supplied more than one value for foo").

There's an interface for enhancing ad_page_contract with pluggable filters, whose names can be used in place of flags (see ad_page_contract_filter). There's also an interface for pluggable filter rules, which determine what filters are applied to arguments (see ad_page_contract_filter_rule).

Note on QQ-variables: Unlike the old ad_page_variables, ad_page_contract does not set QQ-versions of variables. The QQ-versions (had each single-quote replaced by two single-quotes) were only necessary for building up SQL statements directly in a Tcl string. Now that we're using bind variables, the QQ-variables aren't necessary anymore, and thus, ad_page_contract doesn't waste time setting them.

Default Values

Default values are filled in from left to right (or top to bottom), so it can depend on the values or variables that comes before it, like in the example above. Default values are only used when the argument is not supplied, thus you can't use default values to override the empty string. (This behavior has been questioned and may have to be changed at a later point.) Also, default values are not checked, even if you've specified flags and filters. If the argument has the multiple flag specified, the default value is treated as a list. If the array flag is specified, we expect it to be in array get format, i.e. a list of { name value name value ... } pairs. If both multiple and array are set, the value elements of the before-mentioned array get format are treated as lists themselves.

Errors Argument

The -errors block defines custom error messages. The format is a list in array get format with alternating error-names and error texts. The error names can be foo, which means it's thrown when the variable is not supplied. Or foo:flag,flag,..., which means it'll get thrown whenever one of the flags fail. If you want the same error to be thrown for both not supplying a var, and for a flag, you can say foo:,flag,... (a comma immediately after the colon).

Validation Blocks

The -validate is used to fully customized user input validation. The format is a list of named chunks of code, for example:
-validate {
        name {
            code block
        }
        another_name -requires { argname[:filter-or-validation-block-name,...] ... } {
            code block
        }
    }
The name is for use with the -errors block, and for use within the -requires argument of another validation block. The validation blocks will get executed after all flags and filters have been evaluated. The code chunk should perform some validation, and if it's unhappy it should call ad_complain, optionally with an error message. If no error message is specified, the error should be declared in the -errors section.

Each validation block can also have a -requires switch, which takes a list of validations that must already have been successfully passed, for the validation to get executed. The intent is that you want to provide as much feedback as possible at once, but you don't want redundant feedback, like "foo must be an integer" and "foo must be in range 10 to 20". So a check for foo in range 10 to 20 would have a -requires { foo:integer } switch, to ensure that the check only gets executed if foo was successfully validated as an integer.

In the -requires argument, you can specify a list of (1) the name of an argument, which means that the argument must be supplied. Or (2) you can specify argname:filter or argname:validation_block to say that a given filter, flag or valdiation block must have been executed and satisfied for this validation block to get executed. You can have as many requirements as you like.

Switches:
-form (optional)
Optionally supply the parameters directly here instead of fetching them from the page's form (ns_getform). This should be a reference to an ns_set.
-level (optional, defaults to "1")
-context (optional)
-warn (optional, boolean)
-properties (optional)
What properties the resulting document will contain.
Parameters:
docstring (required)
The documentation for your page; will be parsed like ad_proc and ad_library.

ad_page_contract_filter (public)

 ad_page_contract_filter [ -deprecated ] [ -type type ] \
    [ -priority priority ] name proc_args doc_string body

Declare a filter to be available for use in ad_page_contract.

Here's an example of how to declare a filter:

    ad_page_contract_filter integer { name value } {
        Checks whether the value is a valid integer, and removes any leading zeros so as
        not to confuse Tcl into thinking it's octal
    } {
        if { ![regexp {^[0-9]+$} $value] } {
            ad_complain [_ acs-tcl.lt_Value_is_not_an_integ]
            return 0
        }
        set value [util::trim_leading_zeros $value]
        return 1
    }
    
After the filter has been declared, it can be used as a flag in ad_page_contract, e.g.
    ad_page_contract {
        foo:integer
    } {}
    
Note that there's only one global namespace for names. At some point, we might add package-local filters, but we don't have it yet.

The filter proc must return either 1 if it accepts the value or 0 if it rejects it. Any problem with the value is reported using ad_complain (see documentation for this). Note: Any modifications you make to value from inside your code block will modify the actual value being set in the page.

There are two types of filters. They differ in scope for variables that are multiple or array. The standard type of filter (filter classic) is invoked on each individual value before it's being put into the list or the array. A post filter is invoked after all values have been collected, and is invoked on the list or array as a whole.

Switches:
-deprecated (optional, boolean)
used to flag a filter as deprecated
-type (optional, defaults to "filter")
The type of filter; i.e. filter or post. Default is filter.
-priority (optional, defaults to "1000")
Parameters:
name (required)
The name of the flag as used in ad_page_contract
proc_args (required)
the arguments to your filter. The filter must take three arguments, name, value, and parameters, although you can name them any way you want. The first will be set to the name of the variable, the second will be upvar'd to the value, so that any change you make to the value will be reflected in the value ultimately being set in the page's environment, and the third is a list of arguments to the filter. This third argument can have multiple parameters split by | with no spaces or any other characters. Something like foo:range(3|5)
doc_string (required)
Standard documentation-string. Tell other programmers what your filter does.
body (required)
The body is a procedure body that performs the filtering. It'll automatically have one argument named value set, and it must either return the possibly transformed value, or throw an error. The error message will be displayed to the user.

Checks whether the value is a valid object_id, i.e. in the range defined for the SQL datatype "integer", which is the same for Oracle and PostgreSQL. In case, object_types are altered in future versions of OpenACS to e.g. "longinteger", this function has to be adjusted as well. The function is essentially the same as ad_page_contract_filter "integer", but with the additional value range check.

Checks whether the value is more or less a valid phone number with the area code. Specifically, area code excluding leading "1", optionally enclosed in parentheses; followed by phone number in the format xxx xxx xxxx (either spaces, periods or dashes separating the number). This filter matches the beginning of the value being checked, and considers any user input following the match as valid (to allow for extensions, etc.). Add a $ at the end of the regexp to disallow extensions. Examples:

  • (800) 888-8888 will pass
  • 800-888-8888 will pass
  • 800.888.8888 will pass
  • 8008888888 will pass
  • (800) 888-8888 extension 405 will pass
  • (800) 888-8888abcd will pass
  • "" (the empty string) will pass

ad_page_contract_filter_rule (public)

 ad_page_contract_filter_rule name proc_args doc_string body

A filter rule determines what filters are applied to a given value. The code is passed the name of the formal argument and the list of filters currently being applied, and should on that basis modify the list of filters to suit its needs. Usually, a filter rule will add a certain filter, unless some list of filters are already present.

Unlike the filters themselves (registered with ad_page_contract_filter), all rules are always applied to all formal arguments of all pages.

Parameters:
name (required)
filter rules must be named. The name isn't referred to anywhere.
proc_args (required)
the filter rule proc must take two arguments, name and filters, although you can name them as you like. The first will be set to the name of the formal argument, the second will be upvar'd to the list of filters, so that any modifications you make to this list are reflected in the actual list of filters being applied.
doc_string (required)
let other programmers know what your filter rule does.
body (required)
the code to manipulate the filter list.

ad_page_contract_parse_argspec (private)

 ad_page_contract_parse_argspec arg_spec

Parse the argument spec: this is a string in the form <name>:<flag_spec>[,<flag_spec>...]

  • <name> is a token made of any non-space, non-tab and non-colon
  • <flag_spec> is string in the form <flag_name&lgt;[(<flag_parameter>[|<flag_parameter>...])]
  • <flag_parameter> is a string containing arbitrary characters, however, because parenthesys ")" and "(" and pipe "|" are separators in the argspec syntax, they need to be escaped via the character backslash (\)
Examples of valid argspecs:
    - my_page_parameter
    - my_page_parameter:integer
    - my_page_parameter:integer,notnull
    - my_page_parameter:integer,notnull,oneof(1|2|3)
    - another_page_parameter:oneof(this is valid|This, is also valid|This is valid \(as well!\))
