Need help with VisualForce page to prevent users from deleting Leads

Here's my code I'm trying to use but I was only given the code for one user.  I don't know what changes I need to make to have this work for multiple users. I'm not a programmer and would love some help!  Thank you!


<apex:page action="{!if($User.Alias !='user1,user2,user3,user4,user5',
                    null,
                    urlFor($Action.Lead.Delete, $CurrentPage.Parameters.id, [retURL='/00Q'], true)
                    )
                    }" standardController="Lead">
   <apex:pageBlock >
     <apex:PageMessage summary="You are not allowed to delete Leads. Please contact your Field Marketing Manager for assistance." severity="Warning" strength="3"/>
     <apex:pageMessages />
   </apex:pageBlock>
</apex:page>

Hello Jamie Gelep,

Just paste below code in your page and let us know whether it works or not.

<apex:page action="{!if($User.Alias !='',
                    null,
                    urlFor($Action.Lead.Delete, $CurrentPage.Parameters.id, [retURL='/00Q'], true)
                    )
                    }" standardController="Lead">
   <apex:pageBlock >
     <apex:PageMessage summary="You are not allowed to delete Leads. Please contact your Field Marketing Manager for assistance." severity="Warning" strength="3"/>
     <apex:pageMessages />
   </apex:pageBlock>
</apex:page>

Warm Regards,

Thank you.  What is the code if I want to add more than one user alias?

Hi Jamie,

You can associate one custom controller and there in action method you can simply get the all user list and check and set one boolena true false adn then you can render your message on page conditionally from there..

Thanks

Sorry, I'm not a programmer and I don't understand what your answer means.

And, to confirm, the Alias Names I would be adding to this code are the SFDC users that I DO want to give the ability to delete.  All other users, not listed in the code, should get the "can't delete" message.  Is that the way the code is written?  I hope so!  Thanks.

Okay Jamie,

You want users listed in code need to delete the lead.
find below code which will suffice your problem.
If there are multiple users then you just need to add userAlias in OR(||) condition shown below as underline.


<apex:page action="{!if(($User.Alias =='user1' || $User.Alias =='user2' || $User.Alias =='user3'),
                    urlFor($Action.Lead.Delete, $CurrentPage.Parameters.id, [retURL='/00Q'], true),
                    null
                    )
                    }" standardController="Lead">
   <apex:pageBlock >
     <apex:PageMessage summary="You are not allowed to delete Leads. Please contact your Field Marketing Manager for assistance." severity="Warning" strength="3"/>
     <apex:pageMessages />
   </apex:pageBlock>
</apex:page>

Warm Regards,

Hello developer forum!  Hopefully someone can help.  I am using the exact same code to prevent users from deleting records in other objects (Account, Contact, Opportunity, Task) but when I click "Preview" on the Visualforce page, I get the following error:

Invalid parameter for function URLFOR
Error is in expression '{!if($User.Alias !='BJohn', null, urlFor($Action.Account.Delete, $CurrentPage.Parameters.id, [retURL='/001'], true) )}' in component <apex:page> in page preventaccountdelete

Here is the code I'm using:

<apex:page action="{!if($User.Alias !='MYNAME',
null, urlFor($Action.Account.Delete, $CurrentPage.Parameters.id, [retURL='/001'], true)
)
}"
standardController="Account">
<apex:pageBlock >
<apex:PageMessage summary="You are not allowed to delete Accounts"
severity="Warning"
strength="3"/>
<apex:pageMessages />
</apex:pageBlock>
</apex:page>

Thank you very much for any help you can provide!
