Class FieldMergeField

  • java.lang.Object
    • Field
      • com.aspose.words.FieldMergeField
public class FieldMergeField 
extends Field

Implements the MERGEFIELD field.
Retrieves the name of a data field within the merge characters in a mail merge main document. When the main document is merged with the selected data source, information from the specified data field is inserted in place of the merge field.

Example:

Shows how to use MERGEFIELD fields to perform a mail merge.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Create data source for our merge fields
DataTable table = new DataTable("Employees");
table.getColumns().add("Courtesy Title");
table.getColumns().add("First Name");
table.getColumns().add("Last Name");
table.getRows().add("Mr.", "John", "Doe");
table.getRows().add("Mrs.", "Jane", "Cardholder");

// Insert a merge field that corresponds to one of our columns and put text before and after it
FieldMergeField fieldMergeField = (FieldMergeField) builder.insertField(FieldType.FIELD_MERGE_FIELD, true);
fieldMergeField.setFieldName("Courtesy Title");
fieldMergeField.isMapped(true);
fieldMergeField.isVerticalFormatting(false);
fieldMergeField.setTextBefore("Dear ");
fieldMergeField.setTextAfter(" ");

// Insert another merge field for another column
// We don't need to use every column to perform a mail merge
fieldMergeField = (FieldMergeField) builder.insertField(FieldType.FIELD_MERGE_FIELD, true);
fieldMergeField.setFieldName("Last Name");
fieldMergeField.setTextAfter(":");

doc.updateFields();
doc.getMailMerge().execute(table);
doc.save(getArtifactsDir() + "Field.MergeField.docx");

        Example:

        Example:

        Inserts a field into a document using DocumentBuilder and FieldCode.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);

      • unlink

        public boolean unlink()
                      throws java.lang.Exception
        Performs the field unlink.

        Replaces the field with its most recent result.

        Some fields, such as XE (Index Entry) fields and SEQ (Sequence) fields, cannot be unlinked.

        Returns:
        True if the field has been unlinked, otherwise false.

        Example:

        Shows how to unlink specific field
        Document doc = new Document(getMyDir() + "Field.UnlinkFields.docx");
        
        doc.getRange().getFields().get(1).unlink();
      • update

        public void update()
                   throws java.lang.Exception
        Performs the field update. Throws if the field is being updated already.

        Example:

        Inserts a field into a document using DocumentBuilder and FieldCode.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);
        
        // Insert a simple Date field into the document.
        // When we insert a field through the DocumentBuilder class we can get the
        // special Field object which contains information about the field.
        Field dateField = builder.insertField("DATE \\* MERGEFORMAT");
        
        // Update this particular field in the document so we can get the FieldResult.
        dateField.update();
        
        // Display some information from this field.
        // The field result is where the last evaluated value is stored. This is what is displayed in the document
        // When field codes are not showing.
        System.out.println(MessageFormat.format("FieldResult: {0}", dateField.getResult()));
        
        // Display the field code which defines the behaviour of the field. This can been seen in Microsoft Word by pressing ALT+F9.

        // The field type defines what type of field in the Document this is. In this case the type is "FieldDate"
        System.out.println(MessageFormat.format("FieldType: {0}", dateField.getType()));
        
        // Finally let's completely remove the field from the document. This can easily be done by invoking the Remove method on the object.
        dateField.remove();
      • update

        public void update(boolean ignoreMergeFormat)
                   throws java.lang.Exception
        Performs a field update. Throws if the field is being updated already.
        Parameters:
        ignoreMergeFormat - If true then direct field result formatting is abandoned, regardless of the MERGEFORMAT switch, otherwise normal update is performed.

        Example:

        Shows a way to update a field ignoring the MERGEFORMAT switch
        LoadOptions loadOptions = new LoadOptions();
        loadOptions.setPreserveIncludePictureField(true);
        
        Document doc = new Document(getMyDir() + "Field.UpdateFieldIgnoringMergeFormat.docx", loadOptions);
        
        for (Field field : doc.getRange().getFields()) {
            if (((field.getType()) == (FieldType.FIELD_INCLUDE_PICTURE))) {
                FieldIncludePicture includePicture = (FieldIncludePicture) field;
                includePicture.setSourceFullName(getImageDir() + "dotnet-logo.png");
                includePicture.update(true);
            }
        }
        
        doc.updateFields();
        doc.save(getArtifactsDir() + "Field.UpdateFieldIgnoringMergeFormat.docx");
