public class FormClientTemplate extends Template
[Deprecated, use the FormTemplate and SetTemplate instead]
SAMPLE Template class for substituting Default values into html forms The data is retrieved from the client, and sent back to the client later on. This will be used for e-business cards stored on java rings/cards. This template also incorporates the functionallity of the PropsTemplate, as the current scheme doesn't allow composition of template handler classes (at least for now). If a URL contains query data, and the value of the server property "uploadContains" occurs in the URL, then all of the query data is saved in the server on behalf of the client. IF no "uploadContains" string is set, all query data is saved on the server. The following Html entities processed by this class:
input
if the "name" attribute has saved data, the value attribute is replaced by the caved value. This allows default form values to be replaced by previous data submitted to the server by the client.
property
This tag is replaced by the value of a server property.
subst
This tag is replaced by the value previously uploaded to the the server from the client for this value.
tag, /tag
Inserts a "invalid input: '<'" or ">" respectively, allowing parameters to be substituted inside of other entities. For example, suppose the client uploaded the value HOME as http://my.home.com/, and the server withes to create a link to that page. The template fragment: "<a href=<subst HOME>gt; won't work, as nested entities are not allowed. Instead, try: "<tag>a href=<subst HOME>lt;tag>

    • tag_tag

      public void tag_tag(RewriteContext hr)
      Using the current scheme, there is no easy way to substitute into a tag parameter. So we'll invent a "magic" tag (called tag) that will allow us to create entities dynamically
