FUNCTIONS ^

PublishState

Returns the name of the current publish state, given the numeric state.

PublishSelect

Provides a dropdown selection box, as a XHTML code snippet, of the currently available publishing states.

PublishAction

Provides a dropdown selection box, as a XHTML code snippet, of the currently accessible publishing states.

AlignName

Returns the name of the given alignment type, defaults to 'none'.

AlignClass

Returns the class of the given alignment type, defaults to 'nail'.

AlignSelect

Provides a dropdown selection box, as a XHTML code snippet, of the currently available alignment states.

AuthorCheck

Checks whether the current user is the author of the data requested, or has permissions to allow them to access the data. If not sets the BADACCESS error code, otherwise retrieves the data.

MasterCheck

Ensure only a Master user can access a Master user details.

FieldCheck(\@allfields,\@mandatory)

Stores all the input data listed in @allfields, then checks that all the fields listed in @mandatory are provided. Any errors found during parameter parsing both for missing mandatory fields and via Data::FormValidator are then flagged and the error code set.

ParamCheck(\%fields)

Cleans data inputs, then stores all the input data fields in $tvars{data}. All mandatory fields are validated to ensure each has a value. Any errors found during parameter parsing both for missing mandatory fields and via Data::FormValidator are then flagged and the error code set.

The fields hash contains a list of fields, with the keys 'type' and 'html'. 'type' indicates whether the field is mandatory (1) or optional (0). 'html' indicates the level of cleaning required:

    my %fields = (
        linkid      => { type => 0, html => 0 },
        catid       => { type => 0, html => 0 },
        href        => { type => 1, html => 1 },
        title       => { type => 1, html => 3 },
        body        => { type => 0, html => 2 },
    );

    # type: 0 = optional, 1 = mandatory
    # html: 0 = none, 1 = text, 2 = textarea, 3 = no links

'0' should only be used if previous parameter validation via Data::FormValidator has already ensured that only legal characters are used.

'1' removes all HTML tags.

'2' removes disallowed HTML tags and cleans up many tags and whitespace.

'3' removes anything that looks like a link or script tag, with the aim of preventing a XSS attack.
