RE:custom macro return html as a string

Hi,

You could use the (encode)false parameter to display the correct HTML output of your custom macro. Problem could be that we had a bug in the 4.0 version that these macro parameters did not work correctly for custom macros. It was fixed in the 4.1 version that is why I would recommend you to upgrade .

If the upgrade is not possible for you here is a code sample of workaround:



/// <summary>
/// Custom macro handler
/// </summary>
/// <param name="sender">Sender (active macro resolver)</param>
/// <param name="expression">Expression to resolve</param>
/// <param name="match">Returns true if the macro matches (was resolved)</param>
public static string ResolveCustomMacro(MacroResolver sender, string expression, out bool match)
{
match = false;
string result = expression;

// Add your custom macro evaluation
switch (expression.ToLower())
{
case "prepare": // {% ProcessCustomMacro("prepare", "") %}{%test|(encode)false%}
match = true;
result = "";
sender.OnGetValue += new MacroResolver.OnGetValueEventHandler(sender_OnGetValue);
break;
}

return result;
}


static object sender_OnGetValue(string name)
{
// Add your custom macro evaluation
switch (name.ToLower())
{
case "test": // {% ProcessCustomMacro("prepare", "") %}{%test|(encode)false%}
return "<strong> Strong text </strong>";
}
return null;
}

Then you could use this expression to call your macro: {% ProcessCustomMacro("prepare", "") %}{%test|(encode)false%}

Best regards,

RE:custom macro return html as a string

Hi,

Thanks for the workaround;
I can reproduce your sample code

But I need help to use this workaround with a more complexe custom macro

here under my custom macro


public static string ResolveCustomMacro(MacroResolver sender, string expression, out bool match)
    {
        match = false;
        string result = expression;
        switch (expression.ToLower())
        {
            case "productlist.invoice":
                match = true;
                result = GetProductList(sender.SourceObject as ShoppingCartInfo,"fr-fr");
                break;
        }

        return result;
    }

how i have to rewrite this to use your workaround?

RE:custom macro return html as a string

Hi,

Its ok now, I find how to do (new in c# :)


public static class CMSCustom
{
    private static MacroResolver vSender = new MacroResolver();

public static string ResolveCustomMacro(MacroResolver sender, string expression, out bool match)
    {
        match = false;
        string result = expression;
        vSender = sender;
        switch (expression.ToLower())
        {
            case "html":
                match = true;
                result = "";
                sender.OnGetValue += new MacroResolver.OnGetValueEventHandler(sender_OnGetValue);
                break;
        }

        return result;
    }

static object sender_OnGetValue(string name)
    {
        // Add your custom macro evaluation
        switch (name.ToLower())
        {
            case "productlist.invoice": ;
                return GetProductList(vSender.SourceObject as ShoppingCartInfo); 
        }
        return null;
    }

I'm not sure this is a valid c# code but it works !
now, i can have the table of the product list inside my invoice
