Hi,
Before saving all information in the db I would like to get all information that figure into the ‘affectation’ field(generated by set_relation_n_n function).

I tried to use the callback_before_insert function but I have not found the right method to extract information from the array that figure into the callback function that would be called.

 I would appreciate it if you could help me!!

Within the callback_before_insert function use the $post_array['affectation']. I believe this will return either a comma delimited string

e.g. 1234,5678 or

an array('1234' => 'aaaaa', '5678' => 'test')

hi davidoster,

tks for your response . I made a call to a callback_before_insert function and for testing I inserted the code below but I do not think that is functional :

function checking_and_sending($post_array)
    {  
	    $z=$post_array['Affectation']; 
		$count = count($z);
		for ($i = 0; $i < $count; $i++) {
     
       echo "Test : ".$z['$i'] . "\n";
    
   }

Instead of echo do a print_r to tell exactly what's the type and content.

Also make sure the case is correct on 'Affectation'. It could be 'affectation' instead.

Hi davidoster ,

I tried to use the print_r and even the var_dump function. Unfortunately I'm unable to extract data from the selected fields of the list.
Is there any other alternative  that could resolve the pb?
Tks in advance.

Share your code along with the structure of the table(s).
