The list of available field names for the selected layer is displayed in the left hand list; you may then select an entry and click on the 
arrow to enable this field to be displayed to the user. This will then move the entry to the list on the right hand side. To remove an entry from the list to be displayed select it and click on the 
arrow.
| Note |
|---|
If the field name is 'ref' or 'id', info click will fail. To avoid this, rename the field in the source data, or use 'SELECT ref as reference' in the .map file or SQL selection to change the field name on the fly. |
Check box to allow aggregation
This is only displayed for standard Layers and allows you select the field(s) you wish to aggregate.
| Note |
|---|
If you check to aggregate more than one field then you will need to click the Advanced button for the Layer to define the default. |

Add link to field
This specifies whether or not hyperlinks are shown in the Results panel. These hyperlinks are defined in the Link using and / or Link URL. If no field is currently linked then when selecting Add link to field for the first time after starting Studio, then Link using will be set to the current field.
Prior to v5.6.2 this was called Link this field.
Link using
If you pick a field from the list then it will either be used as the URL (if the Link URL is left blank), inserted in place of the {0} in the Link URL or appended to the end of the Link URL if no {0} defined. The Link using drop-down list now supports auto-complete and is sorted in alphabetical order to assist with finding the correct field.
| Tip | ||
|---|---|---|
| ||
The typed characters for auto-complete are not shown to the user and typing behaviour depends on the speed of key presses, e.g. typing p, o, s will select a field beginning {[pos}} (like postcode), but pressing p (pause) o (pause) s will select the first field beginning with s. Pressing s (pause) s pause s will select the third field beginning with s, assuming there is one - if not, then the selection loops round to the first field. |
Link URL
Enter the URL you wish to use as a hyperlink in the Results panel. If you have picked a Link using field then, unless you have entered the parameter {0} the value of the field will be appended to the Link URL.
...
| Note |
|---|
If your Link URL contains a vertical bar “|” then this will need to be replaced by ##vbar##. |
Disable escaping
This entry allows the user to decide whether MapServer should escape the field value or not i.e. leave as is. (from v5.4.14). For instance if this is ticked it will render the HTML in the My House page rather than displaying the raw HTML. For the uninitiated escaping means converting characters like the following in HTML:
| Character | Escaped |
|---|---|
| < | < |
| > | > |
| & | & |
Use Current field as Unique Field
From v5.6.2 this has been removed. If you wish to use the currently selected field as the unique field to be inserted in place of the {0} in the Link URL then check this box.
...
These rules are only available for a My House Classic Layer if My Alerts has been configured.
All field changes
If checked no My Alerts rules will be applied to the record and changes to the number of fields within the record, if a new field is added to the record or if an existing field is removed from the record will trigger an alert. E.g. a new field is added from the left hand list to the right hand list in the Available Fields. If you uncheck this entry then the other three entries become enabled.
Change in number of fields
If you check this entry then an alert will only be triggered if the total number of fields within the record changes.
New fields
If you check this entry then an alert will only be triggered if a new field is added to the record.
Removed fields
If you check this entry then an alert will only be triggered if an existing field is removed from the record.
...
These rules are only available for a My House Layer if My Alerts has been configured. These settings relate to the individual field entries in the right hand panel of the Available Fields. First select a field and then make the required changes to the entries.
Use as My Alert unique key
Check this entry if you wish to use this field as the Unique key for My Alerts. E.g. Planning reference for a Planning record. This will mean that you have a more accurate way of checking whether or not data has changed for an individual record. If you have specified a field as a Unique Key then you will not be able to check for text changes.
| Note |
|---|
You do not have to set a field as a Unique Key. |
Check Text Changes
Check this entry if you wish to trigger an alert if information in this field changes e.g. the Head of the local school changes. If you do not have a Unique Key set for the record then any change to a record will be assumed to be a new entry; if a Unique Key has been set then a change will be reported as a change.
