Event creation from the frontend

[f14m07]

Hi,
Around ten members of the association can programme an event from the frontend. To do so, they must be logged in and go to a specific page where the form can be found.
This form includes the following field at the end:

<h4 style="color: red;">Information du voilier (ne saisir que les 2 ou 3  premières lettres puis choisir dans la liste)</h4>
<div class="input"><label for="location_name">Nom du voilier</label>
#REQ_FIELD{location_name}</div>
<div class="input"><label for="location_address1">Lieu</label>
#_FIELD{location_address1}</div>
<div class="input"><label for="location_city">Ville</label>
#_FIELD{location_city}</div>
<div class="map">#_MAP</div>
#_SUBMIT{Publier ma navigation}

They must then enter the first 2 letters of the location that has already been entered in the database.
Some people do not understand that they have to click on the name of the place that appears in the list and enter a location name that does not exist in the database, then validate the form.
The location entered is not retained as expected, as location creation is not possible using this method. The event is then programmed without a location.
How can I prevent validation when the location is not selected from the list?

well ... currently it is not possible directly. You could create own javascript and check for the value of the hidden location_id field ...
I'm thinking about what way to go about this.

There was already an (undocumented) filter to validate event data when creating an event (now it is documented). So I added a similar filter eme_fs_validate_event_filter too (in dev code). There you can add your own logic.

I already use eme_fs_event_insert_filter. How the two filters will work together?
Will the return value of eme_fs_validate_event_filter be displayed? And will it prevent the incorrectly entered event from being recorded?

[liedekef]

the eme_fs_event_insert_filter changes event content. The new validate filter just validates event data: if something not empty is returned, the validation is considered false and that info (the "something not empty") is shown as reason to the user.

I have tested, but something is wrong in my filter, because the fs event is validate even if I don't choose in the list and put in any letter. My test must be wrong !

function my_fs_validate_event_filter($event){
  $mytexte="";
  if ($event['location_id']==NULL){
    $mytexte="Vous devez choisir votre voilier dans la liste";
    }
    return $mytexte;
}
add_filter('eme_fs_validate_event_filter','my_fs_validate_event_filter');

Could you help me?
I have no error in the console or php log.

if (empty($event['location_id'])) {
should do it.

[f14m07]

I have tested. When the input is empty it was already stopped by using #REQ. However, if the author of the event enters other letters that are not recognised, or if the author does not click on an existing location in the list that appears, the letters he has typed remain and the event is still validated.
In fact I need the location clicked to already exist in the database

I know and understand the problem. Yet my answer remains. Of course it requires that you update to the dev-version . Just tested it here and it works fine (with the "empty"-check)

[f14m07]

I wasn't using the dev version! Now everything is ok. Thanks for everything, it's great
