Hello i have a Ionic Angular project with PHP as backend. I created a search for users but in order for the project to run more faster i put a LIMIT of 20 users in the php function that calls the users and call the next 20 with an Angular PIPE function and so on.
So the user has to scroll down in order for the next 20 users to show and be able to search those names. Otherwise the search results work only for the first 20 names.
That way i can't put any filters also. Any way that a user may do a search in all the users in the database table?
PHP function
$sql = "SELECT f.friend_id,f.friend_two,f.friend_one, U.uid,U.username,U.name,U.first_name,U.last_name, U.profile_pic,U.media_edits,U.updates_count,U.friend_count,U.profile_views,U.group_count,U.bio,U.location,U.artisticBehaviour
FROM users U ";
$sql .= $sql_friends;
$sql .=" LIMIT $offset, $limit";Angular PIPE
import {Pipe, PipeTransform} from '@angular/core';
@Pipe({
name: 'search',
})
export class SearchPipe implements PipeTransform {
/**
* Takes a value and makes it lowercase.
*/
transform(items: any[], terms: string): any[] {
if (!items) return [];
if (!terms) return items;
terms = terms.toLowerCase();
return items.filter(it => {
if (it.group_name) {
return it.group_name.toLowerCase().includes(terms);
}
else if (it.username || it.title)
{
var match_username = it.username ? it.username.toLowerCase().includes(terms) : false;
var match_title = it.title ? it.title.toLowerCase().includes(terms) : false;
return match_username || match_title;
}
else 'No results';
});
}
}
