CGI::FormBuilder::Template::CGI_SSI − FormBuilder interface to CGI::SSI
my $form =
CGI::FormBuilder−>new(
fields => \@fields,
template => {
type => 'CGI_SSI',
file => "template.html",
},
);
This engine adapts FormBuilder to use "CGI::SSI".
You can specify any options which "CGI::SSI−>new" accepts by using a hashref:
my $form =
CGI::FormBuilder−>new(
fields => \@fields,
template => {
type => 'CGI::SSI',
file => 'form.shtml',
sizefmt => 'abbrev'
}
);
In addition to CGI::SSI new arguments, you can also specify "file", "virtual", or "string" argument.
The following methods are provided (usually only used internally):
Returns a reference to the "CGI::SSI" object
Returns a hash of all the fields ready to be rendered.
Uses the prepared hash and expands the template, returning a string of HTML.
In your template, each of the form fields will correspond directly to a "<!−−#echo −−>" of the same name prefixed with "field−" in the template. So, if you defined a field called "email", then you would setup a variable called "<!−−#echo var="field−email" −−>" in your template.
In addition, there are a couple special fields:
<!−−#echo
var="js−head" −−> −
JavaScript to stick in <head>
<!−−#echo var="form−title"
−−> − The <title> of the HTML
form
<!−−#echo var="form−start"
−−> − Opening <form> tag and
internal fields
<!−−#echo var="form−submit"
−−> − The submit button(s)
<!−−#echo var="form−reset"
−−> − The reset button
<!−−#echo var="form−end"
−−> − Just the closing </form>
tag
Let's look at an example "form.html" template we could use:
<html>
<head>
<title>User Information</title>
<!−−#echo var="js−head"
−−><!−− this holds the
JavaScript code −−>
</head>
<!−−#echo var="form−start"
−−><!−− this holds the initial
form tag −−>
<h3>User Information</h3>
Please fill out the following information:
<!−− each of these <!−−#echo
−−>'s corresponds to a field
−−>
<p>Your full name: <!−−#echo
var="field−name" −−>
<p>Your email address: <!−−#echo
var="field−email" −−>
<p>Choose a password: <!−−#echo
var="field−password" −−>
<p>Please confirm it: <!−−#echo
var="field−confirm_password−−>
<p>Your home zipcode: <!−−#echo
var="field−zipcode −−>
<p>
<!−−#echo var="form−submit"
−−><!−− this holds the form
submit button −−>
</form><!−− can also use "tmpl_var
form−end", same thing −−>
As you see, you get a "<!−−#echo −−>" for each for field you define.
However, you may want even more control. That is, maybe you want to specify every nitty−gritty detail of your input fields, and just want this module to take care of the statefulness of the values. This is no problem, since this module also provides several other "<tmpl_var>" tags as well:
<!−−#echo
var="value−[field] −−> − The
value of a given field
<!−−#echo var="label−[field]
−−> − The human−readable label
<!−−#echo var="comment−[field]
−−> − Any optional comment
<!−−#echo var="error−[field]
−−> − Error text if validation fails
<!−−#echo var="required−[field]
−−> − See if the field is required
This means you could say something like this in your template:
<!−−#echo
var="label−email" −−>:
<input type="text" name="email"
value="<!−−#echo
var="value−email"
−−>">
<font
size="−1"><i><!−−#echo
var="error−email"
−−></i></font>
And FormBuilder would take care of the value stickiness for you, while you have control over the specifics of the "<input>" tag. A sample expansion may create HTML like the following:
Email:
<input type="text" name="email"
value="[email protected]">
<font size="−1"><i>You must
enter a valid value</i></font>
Note, though, that this will only get the first value in the case of a multi−value parameter (for example, a multi−select list). Multiple values (loops) in "CGI_SSI" are not yet implemented.
