Attachments (ES5)

Upload Attachment

// Attach file to record (ES5 ONLY!)
function attachFile(tableName, recordSysId, fileName, contentType, content) {
  var attachment = new GlideSysAttachment()

  // Content can be base64 encoded string
  var attachmentSysId = attachment.write(tableName, recordSysId, fileName, contentType, content)

  return attachmentSysId
}

// Example
var base64Content = "SGVsbG8gV29ybGQh" // Base64 encoded
attachFile("incident", incidentSysId, "notes.txt", "text/plain", base64Content)

Read Attachment

// Read attachment content (ES5 ONLY!)
function getAttachmentContent(attachmentSysId) {
  var attachment = new GlideSysAttachment()
  var content = attachment.getContent(attachmentSysId)
  return content
}

// Get attachment as base64
function getAttachmentBase64(attachmentSysId) {
  var attachment = new GlideSysAttachment()
  var bytes = attachment.getBytes(attachmentSysId)

  // Convert to base64
  var base64 = GlideBase64.encode(bytes)
  return base64
}

List Attachments

// Get all attachments for record (ES5 ONLY!)
function getRecordAttachments(tableName, recordSysId) {
  var attachments = []

  var gr = new GlideRecord("sys_attachment")
  gr.addQuery("table_name", tableName)
  gr.addQuery("table_sys_id", recordSysId)
  gr.query()

  while (gr.next()) {
    attachments.push({
      sys_id: gr.getUniqueValue(),
      file_name: gr.getValue("file_name"),
      content_type: gr.getValue("content_type"),
      size_bytes: gr.getValue("size_bytes"),
      created_on: gr.getValue("sys_created_on"),
      created_by: gr.sys_created_by.getDisplayValue(),
    })
  }

  return attachments
}

Copy Attachments

// Copy attachments between records (ES5 ONLY!)
function copyAttachments(sourceTable, sourceSysId, targetTable, targetSysId) {
  var attachment = new GlideSysAttachment()
  attachment.copy(sourceTable, sourceSysId, targetTable, targetSysId)
}

// Copy specific attachment
function copyOneAttachment(attachmentSysId, targetTable, targetSysId) {
  var source = new GlideRecord("sys_attachment")
  if (!source.get(attachmentSysId)) {
    return null
  }

  var attachment = new GlideSysAttachment()
  var content = attachment.getBytes(attachmentSysId)

  return attachment.write(
    targetTable,
    targetSysId,
    source.getValue("file_name"),
    source.getValue("content_type"),
    content,
  )
}

Document Templates (ES5)

Create Document Template

// Create document template (ES5 ONLY!)
var template = new GlideRecord("sys_report_template")
template.initialize()

template.setValue("name", "Incident Summary Report")
template.setValue("table", "incident")
template.setValue("description", "Summary report for incident resolution")

// Template content with placeholders
template.setValue(
  "template",
  "<html>\n" +
    "<head><title>Incident Summary</title></head>\n" +
    "<body>\n" +
    "<h1>Incident Summary Report</h1>\n" +
    "<h2>${number}</h2>\n" +
    "<p><strong>Description:</strong> ${short_description}</p>\n" +
    "<p><strong>Caller:</strong> ${caller_id.name}</p>\n" +
    "<p><strong>Priority:</strong> ${priority}</p>\n" +
    "<p><strong>State:</strong> ${state}</p>\n" +
    "<p><strong>Resolution:</strong> ${close_notes}</p>\n" +
    "<p><strong>Resolved By:</strong> ${resolved_by.name}</p>\n" +
    "<p><strong>Resolved On:</strong> ${resolved_at}</p>\n" +
    "</body>\n" +
    "</html>",
)

template.insert()

Generate Document from Template

// Generate document from template (ES5 ONLY!)
function generateDocumentFromTemplate(templateName, recordSysId) {
  // Get template
  var template = new GlideRecord("sys_report_template")
  if (!template.get("name", templateName)) {
    return null
  }

  // Get record
  var tableName = template.getValue("table")
  var gr = new GlideRecord(tableName)
  if (!gr.get(recordSysId)) {
    return null
  }

  // Process template
  var content = template.getValue("template")
  content = processTemplateVariables(content, gr)

  return content
}

function processTemplateVariables(template, gr) {
  // Replace ${field} and ${field.property} patterns
  var pattern = /\$\{([^}]+)\}/g
  var match

  while ((match = pattern.exec(template)) !== null) {
    var fieldPath = match[1]
    var value = getFieldValue(gr, fieldPath)
    template = template.replace(match[0], value)
  }

  return template
}

function getFieldValue(gr, fieldPath) {
  var parts = fieldPath.split(".")
  var value = gr

  for (var i = 0; i < parts.length; i++) {
    if (!value) return ""

    if (i < parts.length - 1) {
      // Reference field - get referenced record
      value = value[parts[i]].getRefRecord()
    } else {
      // Final field
      if (value.isValidField && value.isValidField(parts[i])) {
        value = value[parts[i]].getDisplayValue() || value.getValue(parts[i])
      } else {
        value = ""
      }
    }
  }

  return value || ""
}

PDF Generation (ES5)

Generate PDF

// Generate PDF from HTML (ES5 ONLY!)
function generatePDF(htmlContent, fileName) {
  try {
    var pdfCreator = new sn_pdfgeneratorutils.PDFGenerationAPI()
    var pdfBytes = pdfCreator.convertToPDF(htmlContent)

    // Return as base64
    return {
      success: true,
      content: GlideBase64.encode(pdfBytes),
      fileName: fileName || "document.pdf",
    }
  } catch (e) {
    gs.error("PDF generation failed: " + e.message)
    return {
      success: false,
      error: e.message,
    }
  }
}

// Generate and attach PDF to record
function generateAndAttachPDF(templateName, recordSysId, fileName) {
  // Generate HTML from template
  var html = generateDocumentFromTemplate(templateName, recordSysId)
  if (!html) {
    return { success: false, error: "Template generation failed" }
  }

  // Convert to PDF
  var pdf = generatePDF(html, fileName)
  if (!pdf.success) {
    return pdf
  }

  // Get table name from template
  var template = new GlideRecord("sys_report_template")
  template.get("name", templateName)
  var tableName = template.getValue("table")

  // Attach PDF
  var attachmentSysId = attachFile(tableName, recordSysId, fileName, "application/pdf", pdf.content)

  return {
    success: true,
    attachment_sys_id: attachmentSysId,
  }
}

Document Workflow (ES5)

Document Approval

// Create document for approval (ES5 ONLY!)
function submitDocumentForApproval(documentSysId, approvers) {
  var doc = new GlideRecord("dms_document")
  if (!doc.get(documentSysId)) {
    return { success: false, message: "Document not found" }
  }

  // Update state
  doc.setValue("state", "pending_approval")
  doc.update()

  // Create approval records
  for (var i = 0; i < approvers.length; i++) {
    var approval = new GlideRecord("sysapproval_approver")
    approval.initialize()
    approval.setValue("sysapproval", documentSysId)
    approval.setValue("approver", approvers[i])
    approval.setValue("state", "requested")
    approval.insert()
  }

  // Notify approvers
  gs.eventQueue("document.approval.requested", doc, approvers.join(","), "")

  return { success: true }
}

Version Control

// Create new document version (ES5 ONLY!)
function createDocumentVersion(documentSysId, newContent, changeNotes) {
  var doc = new GlideRecord("dms_document")
  if (!doc.get(documentSysId)) {
    return null
  }

  // Get current version
  var currentVersion = parseInt(doc.getValue("version"), 10) || 1
  var newVersion = currentVersion + 1

  // Archive current version
  var archive = new GlideRecord("dms_document_version")
  archive.initialize()
  archive.setValue("document", documentSysId)
  archive.setValue("version", currentVersion)
  archive.setValue("content", doc.getValue("content"))
  archive.setValue("created_by", gs.getUserID())
  archive.insert()

  // Update document with new version
  doc.setValue("version", newVersion)
  doc.setValue("content", newContent)
  doc.work_notes = "Version " + newVersion + ": " + changeNotes
  doc.update()

  return {
    document_sys_id: documentSysId,
    version: newVersion,
  }
}

// Get document version history
function getDocumentVersions(documentSysId) {
  var versions = []

  var version = new GlideRecord("dms_document_version")
  version.addQuery("document", documentSysId)
  version.orderByDesc("version")
  version.query()

  while (version.next()) {
    versions.push({
      version: version.getValue("version"),
      created_on: version.getValue("sys_created_on"),
      created_by: version.sys_created_by.getDisplayValue(),
    })
  }

  return versions
}

Attachment Security (ES5)

Check Attachment Access

// Check if user can access attachment (ES5 ONLY!)
function canAccessAttachment(attachmentSysId) {
  var attachment = new GlideRecord("sys_attachment")
  if (!attachment.get(attachmentSysId)) {
    return false
  }

  // Check access to parent record
  var parentTable = attachment.getValue("table_name")
  var parentSysId = attachment.getValue("table_sys_id")

  var parent = new GlideRecord(parentTable)
  return parent.get(parentSysId) // Returns false if no read access
}

MCP Tool Integration

})

// 2. Generate document
await snow_execute_script_with_output({
  script: `
        var html = generateDocumentFromTemplate('Incident Summary', 'inc_sys_id');
        gs.info('Generated: ' + (html ? 'success' : 'failed'));
    `,
})

// 3. Find document templates
await snow_query_table({
  table: "sys_report_template",
  query: "table=incident",
  fields: "name,description,table",
})

Best Practices

File Types - Restrict allowed types
Size Limits - Set max file sizes
Virus Scanning - Scan uploads
Access Control - Inherit from parent
Version Control - Track changes
Cleanup - Remove orphaned files
Templates - Use for consistency
ES5 Only - No modern JavaScript syntax
