Dialogs are Groovy templates that generate forms by mixing static HTML fragments and Groovy calls to the components responsible for building the UI at runtime. The result is a simple but powerful syntax.

h1. Upload Field {anchor:id=CONTref.InsideWCMTemplates.ContentTypes.Dialog.UploadField}

See also: [Common parameters|#CONTref.InsideWCMTemplates.ContentTypes.Dialog.CommonParameters]

* *Example* {anchor:id=CONTref.InsideWCMTemplates.ContentTypes.Dialog.UploadField.Example}

When you create an upload form, you can store an image by two main ways:

* If you want to store the image as a property, use the following code:

{code:groovy}
<%
  String[] fieldMedia = ["jcrPath=/node/exo:image"] ;
  uicomponent.addUploadField("media", fieldMedia) ;		
%>
{code}

* If you want to store the image as a node, use the following code:

{code:groovy}
<%
  String[] hiddenField1 = ["jcrPath=/node/exo:image", "nodetype=nt:resource", "visible=false"] ; 
  String[] hiddenField2 = ["jcrPath=/node/exo:image/jcr:encoding", "visible=false", "UTF-8"] ;
  String[] hiddenField3 = ["jcrPath=/node/exo:image/jcr:lastModified", "visible=false"] ;
  uicomponent.addHiddenField("hiddenInput1", hiddenField1) ;
  uicomponent.addHiddenField("hiddenInput2", hiddenField2) ;
  uicomponent.addHiddenField("hiddenInput3", hiddenField3) ;

  String[] fieldMedia = ["jcrPath=/node/exo:image"] ;
  uicomponent.addUploadField("media", fieldMedia) ;		
%>
{code}

* But, this code is not complete. If you want to display the *upload* field, the image must be blank, otherwise you can display the image and an action enables you to remove it. You can do as follows:

{code:groovy}
<%
	def image = "image";
	// If you're trying to edit the document
	if(uicomponent.isEditing()) { 
		def curNode = uicomponent.getNode();
		// If the image existed
		if (curNode.hasNode("exo:image")) {
			def imageNode = curNode.getNode("exo:image") ;
			// If the image existed and available
			if (imageNode.getProperty("jcr:data").getStream().available() > 0 && (uicomponent.findComponentById(image) == null)) {
				def imgSrc = uicomponent.getImage(curNode, "exo:image");
				def actionLink = uicomponent.event("RemoveData", "/exo:image");
				%>		
					<div>
						<img src="$imgSrc" width="100px" height="80px"/>
						<a href="$actionLink">
							<img src="/eXoResources/skin/DefaultSkin/background/Blank.gif" alt="" class="ActionIcon Remove16x16Icon"/>
						</a>
					</div>
				<%
			} else {
				String[] fieldImage = ["jcrPath=/node/exo:image/jcr:data"] ;
				uicomponent.addUploadField(image, fieldImage) ;								
			}
		} else {
				String[] fieldImage = ["jcrPath=/node/exo:image/jcr:data"] ;
				uicomponent.addUploadField(image, fieldImage) ;								
		}
	}  else if(uicomponent.dataRemoved()) {
		String[] fieldImage = ["jcrPath=/node/exo:image/jcr:data"] ;
		uicomponent.addUploadField(image, fieldImage) ;
	} else {
		String[] fieldImage = ["jcrPath=/node/exo:image/jcr:data"] ;

	}
%>

See also: [Common parameters|#CONTref.InsideWCMTemplates.ContentTypes.Dialog.CommonParameters]

{code:groovy}
<%
  String[] fieldId = ["jcrPath=/node", "editable=false", "visible=if-not-null"] ;
  uicomponent.addMixinField("id", fieldId) ; 
%>
{code}

h1. Action Field {anchor:id=CONTref.InsideWCMTemplates.ContentTypes.Dialog.ActionField}

* *Additional parameters* {anchor:id=CONTref.InsideWCMTemplates.ContentTypes.Dialog.ActionField.AdditionParameters}

|| *Parameter* || *Type* || *Required* || *Description* || *Example* ||

| *selectorIcon* | {{string}} | !images/check.gif! | The action icon. | {{selectorIcon=SelectPath24x24Icon}} |

Depending on the {{selectorClass}}, some other parameters can be added.

For example, the component {{org.exoplatform.ecm.webui.tree.selectone.UIOneNodePathSelector}} needs the following parameter:

|| *Parameter* || *Type* || *Required* || *Description* || *Example* ||
| *workspaceField* | {{string}} | !images/error.gif! | The field which enables you to select a workspace. | {{workspaceField=targetWorkspace}} |

The component {{org.exoplatform.ecm.webui.selector.UIPermissionSelector}} does not need any special parameters.

See also: [Common parameters|#CONTref.InsideWCMTemplates.ContentTypes.Dialog.CommonParameters]

* *Example* {anchor:id=CONTref.InsideWCMTemplates.ContentTypes.Dialog.ActionField.Example}

{code:groovy}

  uicomponent.addActionField("targetPath", fieldPath)  ;
%>
{code}

h1. Interceptors {anchor:id=CONTref.InsideWCMTemplates.ContentTypes.Dialog.Interceptors}

To add an interceptor to a dialog, you can use this method {{*uicomponent.addInterceptor(String scriptPath, String type)*}}
|| *Parameters* ||*Type* ||*Description* ||
| *scriptPath* | {{string}} | The relative path to the script file. |
| *type* | {{string}} | The type of interceptor: {{prev}} or {{post}}. |

* *Example* {anchor:id=CONTref.InsideWCMTemplates.ContentTypes.Dialog.Interceptors.Example}

{code:groovy}
<%
  uicomponent.addInterceptor("ecm-explorer/interceptor/PreNodeSaveInterceptor.groovy", "prev");
%>
{code}

h1. How to add a new ECM template with tabs {anchor:id=CONTref.InsideWCMTemplates.ContentTypes.Dialog.HowToAddNewECMTemplateWithTabs}

To avoid refreshing the first tab for every action execution, add a new private function to the template with tabs.
In the template, you must insert a new piece of code like the following:

{code:groovy}
private String getDisplayTab(String selectedTab) {
  if ((uicomponent.getSelectedTab() == null && selectedTab.equals("mainWebcontent"))
			|| selectedTab.equals(uicomponent.getSelectedTab())) {
		return "display:block";
	}
	return "display:none";
}

private String getSelectedTab(String selectedTab) {
	if (getDisplayTab(selectedTab).equals("display:block")) {
		return "SelectedTab";
	}
	return "NormalTab";
}
{code}

Changing in every event of *onClick* must be done like the following:

{code:html}        
<div class="UITab NormalTabStyle">
  <div class="<%=getSelectedTab("mainWebcontent")%>
    ">
    <div class="LeftTab">
      <div class="RightTab">
        <div class="MiddleTab" onClick="<%=uicomponent.event("ChangeTab", "mainWebcontent")%>"><%=_ctx.appRes("WebContent.dialog.label.MainContent")%></div>
      </div>
    </div>
  </div>
</div>

<div class="UITab NormalTabStyle">
  <div class="<%=getSelectedTab("illustrationWebcontent")%>
    ">
    <div class="LeftTab">
      <div class="RightTab">
        <div class="MiddleTab" onClick="<%=uicomponent.event("ChangeTab", "illustrationWebcontent")%>"><%=_ctx.appRes("WebContent.dialog.label.Illustration")%></div>
      </div>
    </div>
  </div>
</div>

<div class="UITab NormalTabStyle">
  <div class="<%= getSelectedTab("contentCSSWebcontent")%>
    ">
    <div class="LeftTab">
      <div class="RightTab">
        <div class="MiddleTab" onClick="<%=uicomponent.event("ChangeTab", "contentCSSWebcontent")%>"><%=_ctx.appRes("WebContent.dialog.label.Advanced")%></div>
      </div>
    </div>
  </div>
</div>
{code}

Finally, to display the selected tab, simply add it to the style of UITabContent class.

{code:html}
<div class="UITabContent" style="<%=getDisplayTab("mainWebcontent")%>">
{code}

h1. How to prevent XSS attacks {anchor:id=CONTref.InsideWCMTemplates.ContentTypes.Dialog.HowToPreventXSS}
In the content management sytem, its typical feature is enabling JavaScript in a content. This causes the XSS (Cross-site Scripting) attacks to the content displayed in the HTML format.

However, there is no solution to keep JavaScript and to prevent the XSS attacks at the same time, so eXo Content allows you to decide whether
JavaScript is allowed to run on a field of the content template or not by using the {{option}} parameter.

* To allow JavaScript to execute, add "{{options = noSanitization}}" to the dialog template file. Normally, this file is named {{dialog1.gtmpl}}.

* For example: The following code shows how to enable JavaScript in the *Main Content* field of the *Free Layout Wecontent* content:

{code:java}
String [] htmlArguments = ["jcrPath = / node / default.html / JCR: content / JCR: data", "options = toolbar: CompleteWCM, height: '410px ', noSanitization" htmlContent];
{code}

* By default, there is no "{{options = noSanitization}}" parameter in the dialog template file and this helps you prevent the XSS attacks. When end-users input JavaScript into a content, the JavaScript is automatically deleted when the content is saved.
