A form element can be hidden automatically based on the value of another form element. This the ID of the other (referenced) form element. When the value of this property is empty, the form element is not hidden automatically.

A form element can be hidden automatically based on the value of another form element. This is the condition applied to the value of the other form element. Available condition types are:

• 0 (has a value): The form field is hidden when the other field is non-empty.
• 1 (equals): The form field is hidden when the value of the other field equals the hif_v.
• 2 (does not equal): The form field is hidden when value of the the other field does not equal the hif_v.
• 3 (matches regular expression): The form field is hidden when the other field matches the regular expression contained in hif_v.
• 4 (is lower than): The form field is hidden when the other field's value is lower than the hif_v.
• 5 (is greater than): The form field is hidden when the other field's value is greater than the hif_v.
• 6 (lies between): The form field is hidden when the other field's value lies in the range as specified by hif_v. The hif_v must be a range in the format x-y, e.g. 2-37.
• 7 (is lower than or equal to): The form field is hidden when the other field's value is lower than or equal to the hif_v.
• 8 (is greater than or equal to): The form field is hidden when the other field's value is greater than or equal to the hif_v.
• 9 (has no value): The form field is hidden when the other field does not have a value.

A form element can be hidden automatically based on the value of another form element. This is a flag that indicates whether the form element is cleared when it is hidden. Can be set to one of the following options:

• 0 (keep): The value of the form element is not changed when it is hidden.
• 1 (clear): The value of the form element is cleared when it is hidden. For text input fields, the value is set to the empty string; for select fields, all selected options are deselected.
• 2 (reset): The value of the form element is reset to its initial value when it is hidden.

A form element can be hidden automatically based on the value of another form element. This is the value against which the other form element is compared. Whether this property is required and what it must contain depends on the selected condition, see hif_c for further details.

A form element can be hidden automatically based on the value of another form element. This the ID of the other (referenced) form element. When the value of this property is empty, the form element is not hidden automatically.

A form element can be disabled automatically based on the value of another form element. When a form field is disabled, its value cannot be changed anymore. This the ID of the other (referenced) form element. When the value of this property is empty, the form element is not disabled field automatically.

A form element can be disabled automatically based on the value of another form element. When a form field is disabled, its value cannot be changed anymore. This is the condition applied to the value of the other form element. Available condition types are:

A form element can be disabled automatically based on the value of another form element. When a form field is disabled, its value cannot be changed anymore. This is a flag that indicates whether the form element is cleared when it is disabled. Can be set to one of the following options:

• 0 (keep): The value of the form element is not changed when it is disabled.
• 1 (clear): The value of the form element is cleared when it is disabled. For text input fields, the value is set to the empty string; for select fields, all selected options are deselected.
• 2 (reset) The value of the form element is reset to its initial value when it is disabled.

A form element can be disabled automatically based on the value of another form element. When a form field is disabled, its value cannot be changed anymore. This is the value against which the other form element is compared. Whether this property is required and what it must contain depends on the selected condition, see roif_c for further details.

A form element can be disabled automatically based on the value of another form element. When a form field is disabled, its value cannot be changed anymore. When this property is set to 1, the current value of the disabled text input field is discarded and not submitted to the server. This corresponds to the HTML disabled attribute. Otherwise, when set to 2, the value is submitted to the server. This corresponds to the HTML attribute readonly.

A form element can be disabled automatically based on the value of another form element. When a form field is disabled, its value cannot be changed anymore. This the ID of the other (referenced) form element. When the value of this property is empty, the form element is not disabled field automatically.

The minimum number of checkboxes or radio buttons that must be checked or selected. When empty, no restriction is applied.

The maximum number of checkboxes or radio buttons that must be checked or selected. When empty, no restriction is applied.

The data type is used during form validating to ensure the entered data conforms to a certain format. The following built-in data types are currently available:

When not empty, this property refers to the ID of another form field that must have the same value as the form field. The form field is invalid if the value of the form field is different compared to the value of the referenced form field.

A comma separated list of file extensions (without the leading period) an uploaded file must have, such as xml,js. An upload field is invalid if a file with a different file extension is selected. When empty, all extensions are allowed.

The maximum file size in kilobytes a single uploaded file is allowed to have. When set to 0, the file size is unlimited.

The required group to which the form field belongs. If a form element is part of a required group, the form is invalid when no element of the required group has a value. The form becomes valid once the user has filled in at least one form field of the required groups.

The minimum numerical value (inclusive) that must be entered. Contrast this with vmnl, which checks the number of characters, not the numerical value these characters represent. When empty, no restriction is applied.

The minimum number of characters that must be entered in a text field or text area. Please note that this restriction is applied only when the form field is not empty. Thus, when set to 0, the form field is never invalid due to this property. To enforce that the user does not leave the form field empty, use vr.

The maximum numerical value (inclusive) that must be entered. Contrast this with vmxl, which checks the number of characters, not the numerical value these characters represent. When empty, no restriction is applied.

The maximum length of the input that is allowed. If set to 0, the length is unlimited. For input fields and text area, the length of the entered text is checked. For upload fields, the length of the file name is checked.

If set to 0, the form element is not required and can be left empty. Otherwise, if set to 1, the form element is required and a value must be entered.

A form element can be made a required field automatically based on the value of another form element. This the ID of the other (referenced) form element. When the value of this property is empty, the form element is not made a required field automatically.

A form element can be made a required field automatically based on the value of another form element. This is the condition applied to the value of the other form element. Available condition types are:

A form element can be made a required field automatically based on the value of another form element. This is the value against which the other form element is compared. Whether this property is required and what it must contain depends on the selected condition, see vrif_c for further details.

This is the message that is displayed to the user when the value of a form field does not matched the vrule regular expression. If not set, a generic error message is displayed.

A form element can be made a required field automatically based on the value of another form element. This the ID of the other (referenced) form element. When the value of this property is empty, the form element is not made a required field automatically.

This is the regular expression that is used to validate the form field. This must be a valid JavaScript regular expression. Usually it is recommend to use the anchors ^...$ to ensure the whole input conforms to the pattern.
