MvHIDE

---

For each field listed, outputs separate html <input> tags. e.g.

Syntax

<MvHIDE FIELDS = "{ expression } | variable list"> 

<MvHIDE> tags are intended to be used only inside HTML forms. HTML forms are defined like this:

<form method="get | post" action="http://www.mywebsite/program.mvc">
  …
</form>

When a web form is submitted, the variables and their values are passed to the receiving program specified in the action attribute (i.e. http://www.mywebsite/program.mvc) as name/value pairs when the form’s method attribute specifies get or post. This provides a way to pass variable values to the program called by the form. The variables are received as global variables with the names specified in the <input> and other tags.

Attributes

Attribute	Description
FIELDS	Comma-separated list of variable names. The variable names and values will be output to the browser as hidden <input> fields.

Examples

In this example the variables g.Screen and g.Action have been populated. <MvHIDE> is used to output hidden values:

Using MvHIDE to Insert Hidden Fields

<MvASSIGN NAME="g.Screen" VALUE="SFNT">
<MvASSIGN NAME="g.Action" VALUE="ICST">

<form method="post" action="{ l.url_program_name }">
<MvHIDE FIELDS="screen, action>
</form>

The resulting HTML form would look like this:

Resulting HTML Form

<form method="post" action="http://www.mywebsite/program.mvc">
<input type="hidden" name="screen" value="SFNT"><input type="hidden" name="Action" value="INST">
