Canceling saving of an item via onBeforeSaveField function

Hello,

I would like to know if it is possible to execute a php script on submission in order to check a field and to fill in another field before saving data.

For example, I have a field "link".
When a user wants to save the content, the script checks the link and extract the main website and store it into a field (hidden to normal users) "website".
Another feature would be : if the website has already been saved by someone else, it isn't save the link and returns an error message.

Thank you very much.

FLEXIcontent fields are joomla plugins and the have a function that is called before a field value is saved named onBeforeSaveFieldValue(), you will need to duplicate the field (see our FAQ article) and alter this function.

You will need to have PHP/mysql and Joomla programming knowledge in order to do this.

Ok. thank you for your answer.
But, if the script is not successful, can I make it returned an error message in the frontend submission ?

I have another question, you can have content in different languages but can a user select different languages in order to filter content in a category ?

For example, I have alpha in english, beta in french, zeta in spanish in the category gamma.
A user would like just to see alpha and beta (filter through 2 languages).
Is it possible ?


Thank you.

We have the same issue, but not with languagues our problem is with color.

For example I have an extra field called colors it is a SELECT MULTIPLE so the user can say that a t-shirts has black, yellow and red in it. The same can be applies with the CHECKBOX FIELD, this means that an ITEM can have MULTIPLE values assign to it, rigth?

but the filter in FC is always select so the user can only filter one VALUE at a TIME, the never can ser the T-SHIRTS that are YELLOW "AND" BLACK.

Something like this would be nice on a PER FC FIELD we could have a param that we could set:

Filter as SELECT or Filter as ChechBoxes

and in the front end the user could check the values.

Check this example:
www.zillow.com/homes/for_sale/

in the filters the houses are CHECKBOXES.

the query string should be something like:

www.yoursite.com/t-shirts?color=1&color=2

Probably this is a bug change in the fields, templates and views.

It is exactly the issue.

Checkboxes as a filter mode.

Can I fill in other fields through this method ?

To pass an error notice to the frontend you could use:
About the filtering being multi-value and also supporting checkboxes we have an enhancement issue open:
