Allow users to edit a field or read only a field based on user permissions on the NewForm page

Summary:

Recently, a user who wants to implement the following functionality, if the user belongs to the owner group, can edit some fields in a new and edited screen of a list, and only those fields are allowed if the user does not belong to the owner group. Users use shared Hosting environment, which can only be developed through the client.

Scheme:

First let's assume you already know how to modify the NewForm.aspx and EditForm.aspx screen by designer, hide the default list items edit Web Part, and add new list items to edit the Web Part to learn how to add a Web Part to manipulate the field.

After you've done that, we'll just take the default title field as an example, just call <xsl:if test= "ddwrt:ifhasrights (33554432)" > To determine the user's identity to see if the field is displayed. The parameters given in Ifhasrights are called Permissionmark, and we then give all the reference values.

<xsl:if test= "ddwrt:ifhasrights (33554432)" >
    <td width= "75%" class= "Ms-vb" >
        <sharepoint: FormField runat= "Server" id= "ff1{$Pos}" controlmode= "New" fieldname= "Title" __designer:bind= "{ddwrt:databind (' I '), Concat (' ff1 ', $Pos), ' Value ', ' valuechanged ', ' ID ', Ddwrt:escapedelims (String (@ID)), ' @Title '} '  />
        < Sharepoint:fielddescription runat= "Server" id= "ff1description{$Pos}" fieldname= "Title" controlmode= "Edit"  / >
    </td>
</xsl:if>

The above mentioned only the core content, but also some trivial work also need to do:

1. How to write an else statement inside XSL (should be using <xsl:choose>)

2. Displays the value of the field when it is not part of the owner group (should be using <xsl:value-of select= "$Title" >)

There are some interesting things to investigate:

1. How to pass variables to XSL variables from JavaScript (so we can also consider more complex scenarios, such as returning the group information that the user belongs to by WebService)
