エラーの原因は、テンプレート内でrequest.POST.get(parameter.name)を使用する際に、request.POST.getがフィルタの一部として解釈されないようにする必要があります。以下は修正例です。
html
{% with parameter_value=request.POST.get(parameter.name) %} <input type="text" class="form-control" id="{{ parameter.name }}" name="{{ parameter.name }}" value="{% if parameter_value %}{{ parameter_value }}{% endif %}"> {% endwith %}
この修正により、request.POST.get(parameter.name)の評価を一時的な変数parameter_valueに保存し、それを後で使用しています。この変更により、TemplateSyntaxErrorが解消されるかもしれません。再度お試しください。
