Web Content Production with Web Forms [ 132 ] Let's develop a FreeMarker template for rendition: 1. Navigate to the <installed-alfresco>/extras/wcm/forms folder. 2. Create a le named news.ftl in the above-specied path and populate it with the downloaded code from Packt's website. 3. Create a le named blogs.ftl in the above-specied path and populate it with the downloaded code from Packt's website. For your reference, a complete guide to FreeMarker directives is available at: http://FreeMarker.sourceforge.net/docs/. Download the complete code samples from the Packt website. Extensible Stylesheet Language The Extensible Stylesheet Language is divided into two sub-languages: Extensible Stylesheet Language Transformations (XSLT) and Extensible Stylesheet Language-Formatting Objects (XSL-FO). Using XSLT for renditions XSLT is a stylesheet language for XML documents. It is designed to transform XML documents into other formats such as XHTML (Extensible HTML). With XSLT you can add/remove elements and attributes to or from the output le. You can also rearrange and sort elements, perform tests, and make decisions about which elements to hide and display. XSLT uses XPath to nd information in an XML document. XPath is used to navigate through elements and attributes in XML documents. XSLT uses XPath to dene parts of the source document that should match one or more predened templates. When a match is found, XSLT will transform the matching part of the source document into the result document. XSLT is written in stylesheet language and will have .xsl extension. Download from Wow! eBook <www.wowebook.com> Chapter 4 [ 133 ] Some of the fundamentals used for XSLT are: Declare namespaces <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xhtml="http://www.w3.org/1999/xhtml" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:newsevents="http://www.cignex.com/newsevents" xmlns:fn="http://www.w3.org/2005/02/xpath-functions" exclude-result-prefixes="xhtml"> Dene output format <xsl:output method="html" encoding="UTF-8" indent="yes" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" doctype -system="http://www.w3.org/TR/xhtml1/DTD/ xhtml1-transitional.dtd" media-type="text/html"/> Dene Template <xsl:template match="/"> Iterate from a set of repeating elements <xsl:for-each select="/newsevents:news_events">( newsevents is prefix and news_events is complex element defined) Select the values of single occurring element <xsl:value-of select="newsevents:title"/> Provide conditions <xsl:if test="/newsevents:news_events/ newsevents:training-date"> <xsl:value-of select=" newsevents:news_events/ newsevents:training-date"/> </xsl:if> Let's develop an XSL template for rendition: 1. Navigate to the <installed-alfresco>/extras/wcm/forms folder. 2. Create a le named training.xsl in the above-specied path and populate it with the downloaded code from the Packt website. Download the complete code samples from Packt Publishing's website. For your reference, a complete guide to XSL template is available at: http://www.w3schools.com/xsl/. Download from Wow! eBook <www.wowebook.com> Web Content Production with Web Forms [ 134 ] Using XSL-FO for renditions It is designed to provide a mechanism for formatting XML data for print, screen, and other output media. Transforming XML for print is accomplished by transforming an XML document to a Formatting Objects (FO) document, which itself is XML based, via XSLT. The Formatting Objects processor is able to read the FO document and transform it for different types of print output. The most common and best-supported print output is currently Adobe PDF. XSL-FO has the advantage of being able to produce PDFs. The template les are now ready to use. The next task is to associate rendition templates with the web forms created earlier, for this web form should be created in Alfresco. In our case, we have already created a web form in the earlier section. Associating rendition templates to web forms in Alfresco Templates cannot be associated through the web project after the web form is created. Since the web form is already created, the association of template must be done through Company Home | Data Dictionary | Web Forms | <web-form space name>. We will congure our template to the blog's web form. The process is as follows: 1. Ensure that the Alfresco Server is up and running. 2. Go to Company Home | Data Dictionary | Web Forms | <web-form space name> | Blog: Download from Wow! eBook <www.wowebook.com> Chapter 4 [ 135 ] 3. Clicking on Edit Web Form action image under the web form space name (as shown in the previous screenshot) opens the Edit Web Form Wizard window. You may notice that the Edit Web Form Wizard window has four steps, as shown in the following screenshot. The rst step is to delete the previously uploaded XSD (if you want to upload another XSD) le and then upload the XSD, the second step is to congure templates for rendition output, the third step is to dene the workow for form data, and the fourth step is to conrm the web form. 4. In the Step One window, you will notice the information provided about the web project if this corresponding web form is associated. You will also see that the rest of the values are prepopulated on the basis of the attached web form. You are given the facility to upload or delete the existing XSD le, if required. You can also change the Output path pattern. For now we will not make any change, so click on Next. Download from Wow! eBook <www.wowebook.com> Web Content Production with Web Forms [ 136 ] 5. In the Step Two window, the Congure Templates page is shown. This step allows you to upload a template le in order to generate forms in various outputs. Click on Browse to locate and upload the blog.ftl le created in the <installed-alfresco>/extras/wcm/forms folder. After uploading, it will automatically ll up values, such as Rendering Engine, Name, Title, Rendition mimetype, and Output path pattern. By default, the Rendition mimetype will be selected as HTML. You can change the output path pattern and also the extension. This means the le will be created with the specied extension in the specied path. Take a look at the following screenshot and change the output path as specied. We have also changed the extension in order to generate the JSP le. By default, an HTML le will be generated. Click on the Add to List button to add the uploaded templates. You can click on the Add to List button as many times as you want to upload templates. A list of associated templates will be visible at the bottom. The Remove icon is also provided to delete the template in case it's not required. Click on Next: Download from Wow! eBook <www.wowebook.com> Chapter 4 [ 137 ] 6. In the Step Three window, the Congure Workow page is shown. Select the No not now option (this step allows the creation of default workows for form data; you will learn more about this in the next chapter WCM Workow). 7. Clicking on the Next button will take you to the Step Four window, which displays a summary of the web form. Clicking on the Finish button will create the template. You will notice blog.ftl inside the blog space: Download from Wow! eBook <www.wowebook.com> Web Content Production with Web Forms [ 138 ] 8. Continue the previous steps to upload the news.ftl and training.xsl le. Provide the Output path pattern, as shown in the following screenshot, for creating the news template when the Congure Templates pane is open. 9. Provide the Output path pattern as shown in the following screenshot for creating the training template when the Congure Templates pane is open. Download from Wow! eBook <www.wowebook.com> Chapter 4 [ 139 ] Do not proceed to the subsequent sections without rst conguring the templates. The remaining sample solution is based on these web forms and templates. Remember to specify the output path pattern as shown in the previous screenshots for news and blogs. The Alfresco Wiki website (http://wiki.alfresco.com/wiki/WCM_Forms_Rendering) contains information about forms and widgets. Associating web forms and renditions for specic/multiple project(s) Now we have created templates for our web forms. We have also associated our template with the web forms and we are ready to use these forms to create and publish content. We will subscribe to both (news and blog) web forms in this web project and congure each for our web project website's unique content generation. Once congured for a given web project, a Content Contributor can create new web content using web forms via the Create Content wizard. Follow these steps to congure web forms and templates to the web project: 1. Go to Company Home | Web Projects | Cignex. 2. Select Edit Web Project Settings from the action menu. 3. Click on Next. 4. On the next screen, again click on Next. Download from Wow! eBook <www.wowebook.com> Web Content Production with Web Forms [ 140 ] 5. In the Step Three window, you will notice that the Select Web Forms drop down will display all the available forms in Company Home | Data Dictionary | Web Forms. If you want to select from the drop down, then you have to click on the Add to List button. 6. If you want to create a new web form, you can select the Create Web Form button, which will open the Create Web Form wizard. Once the web form is created you can click on the Add to List button to add the newly-created web form. You can see the added web forms in the panel as shown in the following screenshot. You will also see the space of the newly created web form inside Company Home | Data Dictionary | Web Forms. 7. You can also set up the templates if more than one template is associated with each web form selected. You can also select the web form details to change the Output path pattern, Title, Description, and also congure workow. You will learn in detail about conguring workows in the next chapter WCM Workow: 8. Click on Next and then click on Finish. Download from Wow! eBook <www.wowebook.com> Chapter 4 [ 141 ] A few points to be considered are as follows: • As we have learned, we can create a web form using two ways. • Once a web form is created, association of the rendering template is available only with the rst option (Create Web Form). • Output paths for web forms and templates can be different for each web project for the same web form. Using the rst option (Create Web Form), you can create a generic output path and then this can be customized for various projects using the second option (Edit Web Project setting). Creating dynamic content To support creation and editing of web content, Alfresco provides support for a sandbox development model as you have read in Chapter 3, Getting Started with Alfresco WCM. There are multiple methods of adding and creating content for a web project. In addition to creating web content within a project, you can also upload individual les from your computer and perform a bulk import. For more details refer to Chapter 3, Getting Started with Alfresco WCM. Let's assume that we have all the folders in place inside the Cignex web project. We just want to create content for the news and Blog web forms. The link for the news, blog, and training web form is specied inside index.jsp, which is placed under the root folder of the project. Follow these steps: 1. Go to Company Home | Web Projects | Cignex. 2. Expand the web form panel in the user sandbox. You will see a list of web forms, which are congured for the web project. Select Create Content next to the web form: Download from Wow! eBook <www.wowebook.com> . the web project after the web form is created. Since the web form is already created, the association of template must be done through Company Home | Data Dictionary | Web Forms | < ;web- form. web project and congure each for our web project website's unique content generation. Once congured for a given web project, a Content Contributor can create new web content using web. version="1.0" xmlns:xhtml="http://www.w3.org/1999/xhtml" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:newsevents="http://www.cignex.com/newsevents" xmlns:fn="http://www.w3.org/2005/02/xpath-functions" exclude-result-prefixes="xhtml"> Dene output format <xsl:output method="html" encoding="UTF-8" indent="yes" doctype-public=" ;-/ /W3C//DTD
