        <para>Different teams typically like to capture different information
	as users report issues, in some cases, the data required is even
	different from one project to another.  Hence, MantisBT provides the
	ability for managers and administrators to define custom fields as way
	to extend MantisBT to deal with information that is specific to their
	teams or their projects.  The aim is for this to keep MantisBT native
	fields to a minimum.

	Following are some facts about the implementation of
        custom fields in MantisBT:

                <para>Custom fields of type date can be defaulted to a specific dates or to relative dates.  Typically relative dates is the scenario that makes sense in most of the cases.  The format for specific dates is an integer which indicates the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT), which is the format consumed by the PHP <ulink url="http://www.php.net/date">date()</ulink> method.  The relative scenario expects default values like {tomorrow}, {yesterday}, {+2 days}, {-3 days}, {next week}, etc.  The curly brackets indicate that this is a logical value which is then evaluated using the PHP <ulink url="http://www.php.net/strtotime">strtotime()</ulink> function.</para>

	    <title>Dynamic values for Enumeration Custom Fields</title>

	    <para>As discussed earlier, one of the possible types of a custom
	    field is "enumeration".  This type of custom field allows the user
	    to select one value from a provided list of possible values.  The
	    standard way of defining such custom fields is to provide a '|'
	    separated list of possible values.  However, this approach has two
	    limitations: the list is static, and the maximum length of the list
	    must be no longer than 255 characters.  Hence, the need for the
	    ability to construct the list of possible values dynamically.</para>


            <section id="admin.customize.customfields.dynamic.default">
	       <title>Dynamic possible values included by default</title>

	    <para>MantisBT ships with some dynamic possible values, these
	    include the following:

	    	<itemizedlist>
		    <listitem><para>=categories - a list of categories defined
		    in the current project (or the project to which the issue
		    belongs).</para></listitem>
		    <listitem><para>=versions - a list of all versions defined

	    </para>

	    <note><para>The '=' before the name of the dynamic list of options is used

	        <title>Defining Custom Dynamic Possible Values</title>

		<para>If the user selects =versions, the actual custom function
		that is executed is custom_function_*_enum_versions(). The reason
		why the "enum_" is not included is to have a fixed prefix for all
		custom functions used for this purpose and protect against users
		using custom functions that were not intended for this purpose.
		For example, you don't want the user to use
		custom_function_*_issue_delete_notify() which may be overridden
		by the web master to delete associated data in other
		databases.</para>

		<para>Following is a sample custom function that is used to
		populate a field with the categories belonging to the currently
		selected project:

        <title>Enumerations</title>


        <para>Enumerations are used in MantisBT to represent a set of
            possible values for an attribute. Enumerations are used for access
            levels, severities, priorities, project statuses, project view
            state, reproducibility, resolution, ETA, and projection.  MantisBT
            provides the administrator with the flexibility of altering the
            values in these enumerations. The rest of this topic explains how
            enumerations work, and then how they can be customised.
        </para>

        <formalpara>
            <title>How enumerations work?</title>

            <para>
                <filename>core/constant_inc.php</filename> defines the
                constants that correspond to those in the enumeration. These are
                useful to refer to these enumerations in the configs and the code.
                <programlisting>
                    define( 'VIEWER', 10 )
                    define( 'REPORTER', 25 )
                    define( 'UPDATER',  40 )
                    define( 'DEVELOPER', 55 )
                    define( 'MANAGER', 70 )
                    define( 'ADMINISTRATOR', 90 )
                </programlisting>
            </para>
        </formalpara>

        <para>
            <filename>config_defaults_inc.php</filename> includes the defaults for the
            enumerations. The configuration options that are defaulted here are
            used in specifying which enumerations are active and should be used
            in MantisBT.  However, the strings included in the enumerations here
            are just for documentation purpose, they are not shown to the user
            (due to the need for localisation). Hence, if an entry in this
            enumeration is not found in the corresponding localised enumeration
            (i.e. 70:manager), then it will be printed to the user as @70@.

            <programlisting>
                $g_access_levels_enum_string =
                '10:viewer,25:reporter,40:updater,55:developer,70:manager,90:administrator';

            <filename>lang/strings_german.txt</filename> provide the
            localised strings (in this case, in german) for enumerations. But again, the master list is
            the enumeration in the configs, the ones in the language files are
            just used for finding the localised equivalent for an entry. Hence,
            if a user changes the config to have only two types of users
            developers and administrators, then only those will be prompted to
            the users even if the enumerations in the language files still
            includes the full list.
            <programlisting>

            The file <filename>custom_constants_inc.php</filename> is supported for the
            exclusive purpose of allowing administrators to define their own
            constants while maintaining a simple upgrade path for future
            releases of MantisBT. Note that this file is not distributed with
            MantisBT and you will need to create it if you need such
            customisation. In our example, we need to define a constant for the
            new access level.

        <para>
            The file <filename>custom_strings_inc.php</filename> is introduced for a similar reason
            to that of custom_constants_inc.php, which is to define custom
            strings. The advantage of defining them here is to provide a simple
            upgrade path, and avoid having to re-do the changes when upgrading
            to the next MantisBT release. Note that you will need to create this
            file if you need such customisation. The file is automatically
            detected and included by MantisBT code.
            <programlisting>

            <title>Conclusion</title><para>We have covered how enumerations work in general, and how
                to customise one of them. If you are interested in customising
                other enumerations, a good starting point would be to go to "MantisBT
                Enum Strings" section in config_defaults_inc.php. This section
                defines all enumerations that are used by MantisBT.
                For versions that are older than 0.18.0, custom_*_inc.php files are
                not supported, and hence you will need to change in the actual
                constants / language files directly.

            <title>Custom Functions</title>

            <para>Custom functions are used to extend the functionality of
                MantisBT by integrating user writtenfunctions into the issue
                processing at strategic places. This allows the system
                administrator to changethe functionality without re-writing parts
                of the internals of the code.
            </para>
            <para>User versions of these functions are
                placed in a file called custom_functions_inc.php in the
                root directory of MantisBT. This is the same place that the
                "config_inc.php" file modifying MantisBT defaults is placed. In normal
                processing, MantisBT will look for override functions and execute
                them instead of the provided default functions.</para>
            <para>Custom functions have
                    names like custom_function_override_descriptive_name where
                    descriptive namedescribed the particular function. The specific
                    functions are described below. The simplest way tocreate a custom
                    function is to copy the default function, named
                    custom_function_default_descriptive_namefrom the
                    core/custom_function_api.php file to your override file
