如何在Laravel中搜索奇怪的人物？

Question

I have a problem with the search on my site. I have a search input to find products by name. If I type 'leña' (the problem is the strange characters).

This is in the controller

 $termino = $_POST['search']);
 $locale = LaravelLocalization::getCurrentLocale(); //es in this case
 $products = Product::where('title', 'LIKE', "%\"{$locale}\":%{$termino}%");

This is the content of the field 'title' in the database.

{"es":"PAN DE LE\u00d1A"}

The search returns 0 results.

I am sure the problem is the codification and I don´t know how to resolve it.

The codification is utf8mb4.

Thanks

Answer 1

I would simply encode the string before performing the query, eg:

// assuming that $termino is a string 
// json_encode should return the unicode representation
$search = json_encode($termino);

// I changed the where condition a bit, 
// but your own condition is also do fine
$products = Product::where('title->'.$locale, 'LIKE', '%'.$search.'%');

The problem does not really lie on non-English characters. The root issue is that you store a complex data format (JSON) in a single database cell, as opposed to designing your database to hold the individual pieces of data:

create table product_title (
    product_id int(10) not null,
    locale varchar(2) not null,
    title varchar(200),
    primary key (product_id, locale)
);
insert into product_title (product_id, locale, title) values (1, 'es', 'Leña');
insert into product_title (product_id, locale, title) values (1, 'en', 'Wood');

You have a relational database but you haven't designed it around your data structure, so you cannot use most of its features, inclusing basic stuff like WHERE or ORDER BY .

You can fix the design (please, do) or apply a workaround:

• If you have a recent MySQL version, you can make the column of JSON type .

• You can create two versions of your JSON data and expect that database values do not have mixed cases:

   $locale = 'es'; $termino = 'Leña'; $data = [ $locale => ":%{$termino}%" ]; $ascii = json_encode($data); $unicode = json_encode($data, JSON_UNESCAPED_UNICODE); // Use your framework's syntax instead: $sql = 'SELECT * FROM product WHERE title IN (:ascii, :unicode)'; $params = [$ascii, $unicode]; 

Please note there's no sane workaround to use LIKE wildcards too.
