API Problems with implementing search

[JBrinker]

Hi there,

so, I'm quite new to ProcessWire, I am currently building my first site with it, I'm almost done, everything went smoothly.. up until now.

I've been trying to build a search function for hours now and I did get it to work after a while, but not in a very satisfactory manner. As a starting point I used the code from the "site-classic" templates, but the problem is: API-calls don't seem to work.

It all starts off with

if ($q = $sanitizer->selectorValue($input->get->q)) {

Which gives me the following "Error: Call to a member function selectorValue() on a non-object"

Investigating lead me to finding, that it won't just call selectorValue, but also, that $input->get->q does not exist. Actually $input itself is null and so is $sanitizer. Which also leads me to not being able to whitelist q, as I can't call $input->whitelist()

The only way for me to retrieve the query value is via $_GET["q"], which does work.

So this was my main issue.

Another question would be: in the search template of site-classic it is said:

// Search the title, body and sidebar fields for our query text.
// Limit the results to 50 pages. 
// Exclude results that use the 'admin' template. 
$matches = $pages->find("title|body|sidebar~=$q, limit=50"); 

But I don't see any constraint actually excluding admin templates. If I enter the term "template" into my search, I get a nice link in my search results into my backend "/processwire/access/permissions/page-template/". How to prevent this?

I hope you can help me with my issues.

Thanks a lot!

Hi there

Are you implementing this search inside a funciton or in the admin?

If either of those is the case, try wire('input') and wire('sanitizer'), wire('pages') etc. If you're writing the code inside a module you can also use $this->input and $this->sanitizer

If neither of those is the case, could you post the full code that you've got for the search page please?

Nice, this was quick!
And yes, that was inside a function and using wire("input") worked! Thanks a lot!

And to my second question, do you have a suggestion how to solve that as well?

Just list your templates to include, or exclude the "admin" template:

$matches = $pages->find("template=template1|template2|template3, title|body|sidebar~=$q, limit=50");

or

$matches = $pages->find("template!=admin, title|body|sidebar~=$q, limit=50");

The better way of excluding the admin is this:

$matches = $pages->find("has_parent!=2");

This excludes every child of "Admin", which has a hardcoded id of 2. That's more flexible than just excluding admin as for example users ("template=user") are also part of the admin.

Thanks a lot you guys!

Everything works now
