Wasn't finding a way of getting a value from a user's entry in another form, so I've tried my hand at writing a shortcode. It's working, but I'm looking for feedback, improvements (I've got it handling Dynamic Fields, which are used a lot in the project this was written for, but there are probably other field types that could do with special handling?), code clean up, etc. // Find a field value in another form's entries, based on the user ID // usage example: [frm-field-value-from-another-form form_id=5 field_id=465 prefix="Pt 3 Status:" user_id=[411 show="ID"]] add_shortcode( 'frm-field-value-from-another-form', 'frm_find_field_value_from_another_form_using_user_id' ); function frm_find_field_value_from_another_form_using_user_id( $atts ) { $atts = shortcode_atts( array( 'user_id' => '', 'form_id' => '', 'field_id' => '', 'prefix' => '', ), $atts, 'frm-field-value-from-another-form' ); $thisFieldValue = ''; $prefixText = ''; $userID = $atts['user_id']; $formID = $atts['form_id']; $fieldID = $atts['field_id']; if ( $atts['prefix'] != '' ) { $prefixText = $atts['prefix'] . ' '; } if ( $userID != '' ) { global $wpdb; $entryID = $wpdb->get_col( "SELECT id FROM {$wpdb->prefix}frm_items WHERE form_id = '{$formID}' AND user_id = '{$userID}'" ); // If there's no Entry ID (Community has no Actions) then don't do anything more if ( count($entryID) > 0 ) { $fieldType = $wpdb->get_col( "SELECT type FROM {$wpdb->prefix}frm_fields WHERE id = '{$fieldID}'" ); $fieldType = $fieldType[0]; $entryID = $entryID[0]; $entryValue = $wpdb->get_col( "SELECT meta_value FROM {$wpdb->prefix}frm_item_metas WHERE field_id = '{$fieldID}' AND item_id = '{$entryID}'" ); if ( count($entryValue) > 0 ) { $thisEntryValue = $entryValue[0]; // For dynamic fields that store a number and get their display text from anther form if ( $fieldType == 'data' ) { $thisEntryValue = $wpdb->get_col( "SELECT meta_value FROM {$wpdb->prefix}frm_item_metas WHERE item_id = '{$thisEntryValue}'" ); $thisEntryValue = $thisEntryValue[0]; } $thisFieldValue = $prefixText . $thisEntryValue; } } } return $thisFieldValue; // Value of the field }

The only thing I might have done differently is to use $wpdb->get_var() instead of $wpdb->get_col(). It would save a few execution steps because get_var() returns a single value instead of an array.
