Hello,

 

I have the following two attachment variables in the Catalog Item.

How to write an if else statement in email script to check if the attachment variable has attached file or not?

if attachment is there, displays "file is attached" else "please attach a file"

 

Thank you

Hi @Lisa Goldman ,

 

try with below code

 

(function runMailScript( /* GlideRecord */ current, /* TemplatePrinter */ template,
     /* Optional EmailOutbound */
     email, /* Optional GlideRecord */ email_action,
     /* Optional GlideRecord */
     event) {
     var image1 = current.variables.attach_image1;
     var image2 = current.variables.attach_image2;

     if (image1 != '' && image2 != '') { // when both the variables have attachment attached
         var gr = new GlideRecord('sys_attachment');
         gr.addQuery('table_sys_id', current.sysapproval);
         gr.addQuery('content_type', "CONTAINS", "image");
         gr.query();
         while (gr.next()) {
             template.print('<img src=/sys_attachment.do?sys_id=' + gr.getValue("sys_id") + ' width="400" height="300">');
             template.print("<br>");
             template.print("<br>");
         }
     } else if(image1 != '' || image2 != '') { // when only 1 of the variable has attachment attached
var gr = new GlideRecord('sys_attachment');
         gr.addQuery('table_sys_id', current.sysapproval);
         gr.addQuery('content_type', "CONTAINS", "image");
         gr.query();
         if (gr.next()) {
             template.print('<img src=/sys_attachment.do?sys_id=' + gr.getValue("sys_id") + ' width="400" height="300">');
             template.print("<br>");
             template.print("<br>");
         }
}else{
         return false;
     }
 })(current, template, email, email_action, event);

 

Thanks,

Danish

Hello @Danish Bhairag2 

It supposed to print on the email body.  I think I got it to works:

@Danish Bhairag2 

I don't think my code is correct.  I would like to validation when an end user attached the file on the portal.  Thanks

Hi @Lisa Goldman 

 

Any particular reason for doing this validation in email script ? You can check for the attachments with an On-Submit Catalog Client Script as well to ensure the attachments are available. Please refer :
