Dynamicaly enable disable an object in a form

[gniko]

I have a form that includes a lookup table. I try to enable/disable another field of the form depending on the user selection.
To do it, I tried the following PHP code in the AB (AfterBrowse) PHP of the lookup value:

Code: Select all

// Get the object type id
$recid = nuLookupRecord()->ID;
$s = "SELECT * FROM category WHERE category_id = '{$recid}'";
$t  = nuRunQuery($s);
$r  = db_fetch_object($t);
//nuDebug($r->category_countable);
if ($r->category_countable==1){
   nuAddJavascript ("nuEnable('device_count');");
}else{
    nuAddJavascript("nuDisable('device_count');");
}

'device_count' is the name of the field to be enabled disabled
nuEnable('device_count');
and
nuDisable('device_count');
work as expected when used in the LUJS but not when called from the PHP code.

gniko,

nuAddJavascript won't have any effect only in Before Browse and Before Edit.

After Browse is for automating populating fields on an Edit Form.

I would suggest you update another - maybe hidden field.

eg.
After Browse (AB)

Code: Select all

$recid = nuLookupRecord()->ID;
$s = "SELECT * FROM category WHERE category_id = '{$recid}'";
$t  = nuRunQuery($s);
$r  = db_fetch_object($t);

nuSetFormValue('hidden_value', $r->category_countable);

Javascript (JSLU)

Code: Select all

if ($('#hidden_value').val() == 1){
   nuEnable('device_count');
}else{
    nuDisable('device_count');
}
