Today we will learn step by step how to create site creation app in SharePoint 2013.

In SharePoint Server 2013, a Site Creation App allows an option to the users to create a site even if the user has no permission to create a site from a web template that we can configure either custom or OOTB. For example, if we use SharePoint as a social platform and use community sites and community portalm then we can provide an option to user this app where the user can create a community site (site template will be configured in app code).

Prerequisites for setting up your development environment to work with a Site Creation App

To create the SharePoint Hosted App that uses the JavaScript object model to work with a Site Create App, you’ll need:

• Visual Studio 2012
• App Configuration in server
• Local administrator permissions for the logged-on user

Create a farm solution and SharePoint-Hosted App

Use the following procedure to create a farm solution and SharePoint-Hosted App in Visual Studio 2012:

• Run Visual Studio as administrator, and choose “File” -> “New” -> “Project…”.
• In the New Project dialog box, choose “.NET Framework 4.5″ from the drop-down list at the top of the dialog box.
• In the Templates list, expand “Office/SharePoint”, choose “Apps”, and then choose the “App for SharePoint 2013″ template.
• Name the project “SiteApp”, and then choose the “OK” button.
• In the SharePoint Customization Wizard dialog box, choose “Deploy as a farm solution” and then choose the “Finish” button.
• In Solution Explorer, open the shortcut menu for the SiteApp project, and expand the Pages folder and click on the default.aspx page.
• In the markup of the “Default.aspx” file, paste the following code between the “Main” asp:Content tags. This code defines controls and script references.

HTML

<div>
Site Name: <inputtype=”text”id=”siteName”value=””/>
<inputtype=”button”onclick=”createSite()”name=”Create”value=”Create”/>
</div>

• Open the “App.js” file under the Script folder. Replace with the following code:

function getQueryStringValue(key) {
    var returnValue = “”;
    var params = document.URL.split(“?”)[1].split(“&”);
    var strParams = “”;
    for (var i = 0; i < params.length; i = i + 1) {
        var singleParam = params[i].split(“=”);
        if (singleParam[0] === key) {
            return decodeURIComponent(singleParam[1]);
            break;
        }
    }

    return returnValue;
}
function createSite() {

    var hostWebUrl = getQueryStringValue(“SPHostUrl”);
    spcontext = new SP.ClientContext.get_current();
    //then use the host web URL to get a parent context -this allows us to get data from the parent
    parentCtx = new SP.AppContextSite(spcontext, hostWebUrl);
    currentWeb = parentCtx.get_web();

    context.load(currentWeb);
    context.executeQueryAsync(onCreationSuccess, OnFailure);
}

function onCreationSuccess() {
    //alert(“In onCreationSuccess”);
    var appInstanceID = currentWeb.get_appInstanceId();
    var webCreateInfo = new SP.WebCreationInformation();
    webCreateInfo.set_description(“This site created from Javascript”);
    webCreateInfo.set_language(1033);
    var site = $(“#siteName”).val();
    webCreateInfo.set_title(site);
    webCreateInfo.set_url(site);
    webCreateInfo.set_useSamePermissionsAsParentSite(true);

    webCreateInfo.set_webTemplate(“COMMUNITY#0″);// you can add webtemplate as per your choice
    web = currentWeb.get_webs().add(webCreateInfo, false, appInstanceID);

    context.load(web);
    context.executeQueryAsync(onSuccess, OnFailure);

}

function onSuccess() {
    alert(“Web created”);
}
function OnFailure(sender, args) {
    alert(args.get_message());
}

• Open the “AppManifest.xml” file and set the permission to “Site Collection as Full Control”
• To test the solution, on the menu bar, choose “Deploy”.
