Use this filter to change the field’s value after being retrieved from the database. Use in conjunction with gform_save_field_value to perform low level transformations, such as encrypting/decrypting a field.


The base filter which would run for all forms and all fields would be used like so:

add_filter( 'gform_get_input_value', 'your_function_name', 10, 4 );

To target a specific form append the form id to the hook name. (format: gform_get_input_value_FORMID)

add_filter( 'gform_get_input_value_10', 'your_function_name', 10, 4 );

To target a specific field append both the form id and the field id to the hook name. (format: gform_get_input_value_FORMID_FIELDID)

add_filter( 'gform_get_input_value_10_3', 'your_function_name', 10, 4 );


  • $value string

    Field value to be filtered.

  • $entry Entry Object

    Current entry object.

  • $field Field Object

    Current Field object.

  • $input_id float

    For multi-input fields (i.e. name, address, checkboxes), this parameter will hold the input ID. For single input fields, this parameter will be blank.


1. Decode all values

This example assumes the field values were base 64 encoded, and decodes them so that they can be properly displayed. View gform_save_field_value for an example on how to encode the fields.

add_filter( 'gform_get_input_value', 'decode_field', 10, 4 );
function decrypt_field( $value, $entry, $field, $input_id ) {
    return base64_decode( $value );

This example uses the GFCommon::decrypt() method.

add_filter( 'gform_get_input_value', 'decode_field', 10, 4 );
function decrypt_field( $value, $entry, $field, $input_id ) {
    return GFCommon::decrypt( $value );

2. Decode values for a specific form

This is another example where you may select a specific form and specific fields to decode. It is also assumed that the values were base 64 encoded.

add_filter( 'gform_get_input_value', 'decode_field', 10, 4 );
function decode_field( $value, $entry, $field, $input_id ) {

    //if not the form with fields to decode, just return the unaltered value without checking the fields
    if ( absint( $entry['form_id'] ) <> 94 )
        return $value;

    //array of field ids to decode
    $decode_fields = array( 1,2,3 );

    //see if the current field id is in the array of fields to decode; decode if so, otherwise return unaltered value
    if ( in_array( $field->id, $decode_fields ) ) {
        return base64_decode( $value );
    } else {
        return $value;


This code should be placed in the functions.php file of your active theme.

Source Code

gf_apply_filters( 'gform_get_input_value', array( $field->formId, $field->id ), $val, $lead, $field, $input_id )

This filter is located in the following methods in forms_model.php

  • GFFormsModel::get_field_value_long()
  • GFFormsModel::build_lead_array()


The base filter was added in Gravity Forms The form and field specific versions were added in Gravity Forms
