Controller Fields for Contact Form 7 vs Leaflet Map

Contact Form 7 is an excellent WordPress plugin and one of the top choices of free WordPress plugins for contact forms. Controller Fields makes it even more awesome by adding dynamic content capabilities. This plugin provides new form tags for select fields, checkboxes, and radio buttons so you can use them to control the display of other fields and content. Some examples might include: Hiding or revealing additional form fields based the current value in a dropdown Hiding or revealing content when users click a checkbox Hiding or revealing information based on which radio button is currently selected Controllers and controlled fields can be nested The possibilities are endless! View Demo Preview this plugin in the WordPress Playground, a sandbox environment where you can explore the features of this plugin, both in the WordPress backend as an admin user and on the frontend. WHAT DOES IT DO? This plugin creates three (3) new form tags for controlling the appearance of other form tags (aka “controller”) and a special form tag generator button to output the HTML needed to wrap the controllable form tags inside. HOW TO USE IT After installing and activating the plugin, you will have four (4) new buttons at the top when creating or editing a Contact Form 7 form: select controller, checkbox controller, radio controller, and controlled form tag wrapper. Most of the options in their tag generators will be familiar to Contact Form 7 users but there have been some upgrades. Id Attribute The frontend script relies on unique IDs for the controller form tags, so be sure to always set one! Options There are three (3) ways you can define your options. The first method is simply typing your options with each one on a new line, e.g.: Apples Bananas Dragonfruit The second method is similar, but it allows you more control over the value and label by using | to separate them, e.g.: fruit_1 | Apples fruit_2 | Bananas fruit_3 | Dragonfruit The third method is dynamic in that you can use a shortcode to populate your options with two important provisions: The shortcode should NOT include the normal square brackets ([ and ]). So, instead of [my_shortcode key='value'] you would use my_shortcode key='value'. Any parameters in the shortcode must use single quotes. That is: my_shortcode key='value' and not my_shortcode key="value" Shortcodes used here should return a string value with the option or option group HTML. Default value This field can take static text or a shortcode. If using a shortcode, the same syntax applies from the options field. However, this field also has a few more needs: The text/shortcode must first have apostrophes converted to it’s HTML entity code, ' After that, it must be URL encoded so that spaces become %20 and other non-alphanumeric characters are converted. Placeholder Only available for the select controller form tag, this field can take static text or a shortcode. If using a shortcode, the same syntax applies from the options field. However, this field also has a few more needs: The text/shortcode must first have apostrophes converted to it’s HTML entity code, ' After that, it must be URL encoded so that spaces become %20 and other non-alphanumeric characters are converted. Read Only Attribute Simply check this box if you do not want to let users edit this field. It will add the readonly attribute to your form field. Disabled Attribute Simply check this box if you do not want to submit this field in the form. It will add the disabled attribute to your form field.

Add a map generated with LeafletJS: an open-source JavaScript library for mobile-friendly interactive maps. Map tiles are provided by default through OpenStreetMap, or MapQuest (with an app key). Can be set per map with shortcode attributes or through the dashboard settings. Maps Simply create a map with: [leaflet-map] Lookup an address with: [leaflet-map address="chicago"] When using the OpenStreetMap Nominatim geocoder, the plugin sends a contact email in the request user agent. By default this uses the site admin email, but you can override it in the plugin settings or with the leaflet_map_nominatim_contact_email filter. add_filter('leaflet_map_nominatim_contact_email', function ($email) { return '[email protected]'; }); Know the latitude and longitude of a location? Use them (and a zoom level) with: [leaflet-map lat=44.67 lng=-63.61 zoom=5] Add a marker under your map shortcode, like so: [leaflet-map] [leaflet-marker] Want more? Make more (and fit the map to contain all of them): [leaflet-map fitbounds] [leaflet-marker address="tokyo"] [leaflet-marker address="oslo"] [leaflet-marker address="cairo"] [leaflet-marker address="toronto"] You can even add popups (to any shape) with their names: [leaflet-map fitbounds] [leaflet-marker address="tokyo"]Tokyo[/leaflet-marker] [leaflet-marker address="oslo"]Oslo[/leaflet-marker] ... Add a link to the popup messages the same way you would add any other link with the WordPress editor. Other Shapes, GeoJSON, and KML Add a line to the map by adding [leaflet-line]. You can specify the postions with a list separated by semi-colon ; or bar | using lat/lng: [leaflet-line latlngs="41, 29; 44, 18"] or addresses: [leaflet-line addresses="Istanbul; Sarajevo"], or x/y coordinates for image maps. Add a circle to the map by adding [leaflet-circle]. You can specify the position using lat and lng and the radius in meters using radius. You can also customize the style using Leaflet’s Path options. Example: [leaflet-circle message="max distance" lng=5.117909610271454 lat=52.097914814706094 radius=17500 color="#0DC143" fillOpacity=0.1]. Or you can add a geojson shape via a url (make sure you are allowed to access it if it’s not hosted on your own server): [leaflet-geojson src="https://example.com/path/to.geojson"]. Add custom popups with field names; try out the default src file and fields like so: [leaflet-map fitbounds] [leaflet-geojson]{name}[/leaflet-geojson] name is a property on that GeoJSON, and it can be accessed with curly brackets and the property name. Image Maps Alternatively, you could use a plain image for visitors to zoom and pan around with [leaflet-image src="path/to/image/file.jpg"]. See screenshots 3 – 5 for help setting that up.
