GET ID


02 July 2019, 3:26 AM

Hello,

I have a small question. Is there a easy way to get the id from the url?
I think the normal $ _GET ['id'] is blocked ...
Is this function?
$groupid = param_integer('id');

Thank you! smile

Hi

Yes if you are wanting to get an integer value from the url you can use:

 $id = param_integer('id');

if you are wanting the page to load both in instances with or without an id supplied

 $id = param_integer('id', null);

if you are wanting the page to load both in instances with or without an id supplied but want to default to a specific value, eg '27'

 $id = param_integer('id', 27);

 

There are similar options for a string

param_alpha() -- for alpha strings only

param_alphanum() -- for alpha stings and numbers

param_alphanumext() -- for alpha strings / numbers / underscore / dot / dash

param_variable() -- no checking done so not recommended to use

(only use if you can't control the info coming from 3rd party application)

see htdocs/lib/web.php for more info

Cheers

Robert
