selector like "field1=val1|field2=val2"

[theoretic]

Hello there! And thanks for Processwire!

It may appear a noob question but what about selectors like "field1=val1||field2=val2"? I mean that the page we're looking for should have field1=val1 OR field2=val2 . There's plenty of examples for cases like "field=val1|val2" but it's another case.

Practical example: frontpage uder registration. User should enter nick and email, and both of them should be unused by other registered users. It's logical to use something like

$userTest = $users->get("nick={$input->post->nick}|email={$input->post->email}");

But this doesn't work.

That's the best practice in this case? Thanks in advance!

That's what OR-groups are for.

$userTest = $users->get("(nick={$input->post->nick}), (email={$input->post->email})");

Btw., don't forget to sanitize your input before using it in selectors.

Example code was missing a comma

@BitPoet, thanks! It just works. But the syntax is far from being obvious. Maybe it could b a good idea to include "field1=val1|field2=val2" syntax in further PW releases. As far as i see it will not create conflicts with the existing selector syntax.

You may also specify an either/or value, by separating each of the values that may match with a pipe character "|". More details and examples can be found in the "OR selectors" section below.

Its to separate different values of the selector...
