Having problems getting values from foreach - php

Question

trying to get id from each person
$person = $request->input('person');
//values for person: Murdock,Wayne
$values = explode(',' , $person);
if(count($values) > 1) {
//count($values) = 2
foreach($values as $val) {
$get_id = Tag::where('name', $val)->get();
foreach($get_id as $get) {
echo "id=".$get->id;
$result= FileTags::with('file')->where('tag_id', $get->id)->get();
}
}
}
when i do echo $get->id just getting id=1, when is supossed to be id=1 and id=2
Murdock -- id:1
Wayne -- id:2
|table filetags|
| id | tag_id | file_id |
| 1 | 1 | 2 |
| 2 | 1 | 3 |
| 3 | 2 | 4 |
| 4 | 3 | 1 |
$result = FileTags::with('file')->where('tag_id', $id->id)->get();
I should get files with id 2,3 and 4
Model TAG
public function fileTag() {
return $this->hasMany('App\FileTags');
}
Model Archive
protected $table = 'files';
public function fileTag() {
return $this->hasMany('App\FileTags');
}
Model FileTags
public function tag() {
return $this->belongsTo('App\Tag' , 'tag_id');
}
public function file() {
return $this->belongsTo('App\Archive', 'file_id');
}
Thanks for the help.
EDIT:
|table tag|
| id | name |
| 1 | Murdock |
| 2 | Wayne |
Result from echo $obt_id;
[{"id":1,"name":"Murdock","description":"Description","type":"0","status":"1","created_at":"2016-07-20 18:01:14","updated_at":"2016-07-20 18:01:14"}][]
from var_dump($obt_id)
array (size=1)
0 =>
object(App\Tag)[267]

You could create a Variable, $result; initialize it as an Empty Arrayand then simply push all the Results of evaluating the code: FileTags::with('file')->where('tag_id', $get->id)->get() into that the $result Array. And, in the end, Check if the $result Array is not empty. If it's not, you may simply implode it using comma (Assuming it is a String) and echo your Results...
<?php
$person = $request->input('person');
//values for person: Murdock,Wayne
$values = explode(',' , $person);
$result = array(); // <== INITIALIZE TO AN EMPTY ARRAY...
if(count($values) > 1) { //<== $values NOT values...
//count(values) = 2
foreach($values as trim($val)) { //<== TRY TRIMMING OFF WHITE SPACES.
$get_id = Tag::where('name', $val)->get();
foreach($get_id as $get) {
echo "id=".$get->id;
// PUSH THE DATA INTO THE ARRAY...
$result[] = FileTags::with('file')->where('tag_id', $get->id)->get();
}
}
}
// CHECK IF $result IS NOT EMPTY
if(!empty($result)){
// CONVERT THE ARRAY TO A STRING (ASSUMING ITS CONTENT ARE NOT OBJECTS OR ARRAYS)
$result = implode(", ", $result);
// ECHO OUR YOUR RESULT...
echo $result;
}
