add()

static string WebUtil::StaticTextTemplateBase::add ( Qore::Program  p, string  fn, string  name, string  src  )

static

adds a template function to a template Program object

Example:

string qhtml = "<form id=\"upload_form\" enctype=\"multipart/form-data\" method=\"post\" action=\"{{ $URL_PREFIX }}upload-file">
    <fieldset class=\"workflow_list\">
        <legend>Step 1: Select Workflow</legend>
          <select class=\"worfklows\" name=\"workflow\" id=\"workflow\">
            {% foreach my hash<auto> $h ($ctx.workflows.pairIterator()) { %}
            <option value="{{ $h.key }}">{{ $h.value.label }}</option>
            {% } %}
          </select>
    </fieldset>
</form>";
StaticTextTemplateBase::add(p, "/html/index.qhtml", qhtml, "t0");

Parameters

p	the Program object to add the template function to
fn	the name of the template function
name	the name of the template
src	the source of the template; Qore source code is delimited as follows: expressions: Qore expressions are delimited by double curly brackets: {{ }}; such expressions are expected to return a string value that will be inserted directly into the text generated by the template statements: Qore statements are delimited by a curly bracket and percent sign: {% %}; these statements can be any Qore code legal for the template Program object; for example loop constructs are often used (see the example above)

The ctx hash variable is always present in the template code; this is the call context variable, and is set to the same value as the cx argument in HttpServer::AbstractHttpRequestHandler::handleRequest() plus any context added by the actual handler handing the request. In the example above, a "workflows" key assigned to a hash has been added to the call context variable.

Returns

the source code of the generated template (without Program overhead)
