Private Field Details

$size

private integer $size

>>-1<<

HTML size attribute.

$accept

private string $accept

>>""<<

HTML accept attribute.
Note that not all browsers support that attribute.

$length_e

private string $length_e

>>""<<

Length error message.
Error message used to indicate that the length of the value of the elementis eigther smaller than minlength or bigger than maxlength. If no messageis given the length gets not validated. Used together with maxlengthand minlength you can control the length of the user input.

$minlength

private integer $minlength

>><<

See Also $length_e, $maxlength

$maxlength

private integer $maxlength

>>-1<<

Maximum length of the value of the element ( = user input)
Used as HTML attribute (only form_element_text)as well as for the serverside validation.

See Also $length_e, $minlength

$valid_e

private string $valid_e

>>""<<

Regular expression error message
Error message used to indicate that the value of the elementdoesn't math the regular expression specified with valid_regex.If no message is given the value gets not validated. Used withvalid_regex and optionally valid_icase you can make sure thatthe user input follows certain rules, e.g. some that doa simple e-mail validation. As with to old oohforms ereg() and eregi()are used to test the value.

See Also $valid_regex, $valid_icase

$valid_regex

private string $valid_regex

>>""<<

Regular expression used to validate the value of the element ( = user input)

See Also $valid_e, $valid_icase

$valid_icase

private boolean $valid_icase

>>false<<

Regular expression validation case insensitive?

See Also $valid_e, $valid_regex

$optional_fields
