JSON format is saved in MySql column like this:
[{"id":1},{"id":2},{"id":3,"children":[{"id":4},{"id":5}]}]
And I did this in Laravel Blade;
#php
$json = $categories->column;
$array= json_decode($json , true);
#endphp
#foreach ($array as $key => $value)
<li>{{ $value["id"] }}</li>
#endphp
And I get a result like this;
1
2
3
But I can't get children results. What should I do for it? Thanks for your help.
Try this code, You should have another loop for children if exists.
#php
$json = $categories->column;
$array= json_decode($json , true);
#endphp
#foreach ($array as $key => $value)
<li>{{ $value["id"] }}</li>
//another loop for children if exists
#if (isset($value["children"]))
#foreach ($value["children"] as $child_key => $child_value)
<li class="childs">{{ $child_value["id"] }}</li>
#endforeach
#endif
#endforeach
Your output will be this.

I want to echo arry elemnts in view
followings are my code (controller)
$next_d_dts= \DB::table('tb_billing_cycle')->select('next_due_bill_date')->where('customer_id',$row->customer_id)->get();
return view('invoice.view')->with('next_d_dts',$next_d_dts);
I can print it using print function, eg:
print_r($next_d_dts);
Output:
Array ( [0] => stdClass Object ( [next_due_bill_date] => 2019-03-28 ) [1] => stdClass Object ( [next_due_bill_date] => 2020-02-28 ) )
You need to iterate over the collection of objects:
#foreach ($next_d_dts as $object)
{{ $object->name }}
#endforeach
If you just want to see its contents but not stop the script:
{{ var_dump($next_d_dts) }}
You've also asked how to iterate without Blade:
foreach ($next_d_dts as $object) {
echo $object->name;
}
#foreach($next_d_dts as $value)
{{$value['next_due_bill_date']}}
#endforeach
you should used foreach loop in laravel like this
#foreach ($next_d_dts as $value)
<p>Some text here{{ $value->id }}</p>
#endforeach
for more information read Laravel Manual blade template
Also you can used
dd($next_d_dts) //The dd function dumps the given variables and ends execution of the script
You can convert it into array using toArray() and iterate over it
$next_d_dts= \DB::table('tb_billing_cycle')->select('next_due_bill_date')->where('customer_id',$row->customer_id)->get()->toArray();
In view
#foreach($next_d_dts as $value)
{{ $value['column_name'] }}
#endforeach
Or
print_r($next_d_dts)
#foreach($array as $item)
{{$item}}
#endforeach
Simple.
you need to use Blade Loops syntax invoice.view.blade.php
#foreach($next_d_dts as $next )
{{ $next }}
#endforeach
I got the following from controller :
{"cat_id":17,"course":"Maths",
"subcat_info":[{"subcat_id":43,"title":"Test","cat_id":17}]}
Now I want to fetch the title of (title:test) from subcat_info.
I tried following foreach in blade view (result is blank)
#foreach($cats as $cat)
{{ $cat->subcat_info[0]->title }}
#end
How to get title from this?
Try this
$json = '{
"cat_id":17,
"course":"Maths",
"subcat_info":[{
"subcat_id":43,
"title":"Test",
"cat_id":17
}]
}';
$array = json_decode($json,true);
echo $array['subcat_info'][0]['title'];
Output
Test
#foreach($cats as $cat)
{{ $cat->course }} // if you like to print the "title" of the category
#foreach($cat->subcat_info as $subcat)
{{ $subcat->title }}
#endforeach
#endforeach
I have json column where i save my orders data in it, code below is sample of that data:
[{"id":27,"name":"new product","price":7246,"quantity":"1","attributes":[],"conditions":[]}]
with code above if i have such loop in my edit page i'm able to get orders info:
#foreach($order->product_data as $data)
{{ $data['quantity'] }}
#endforeach
until here everything is good, but the problem when comes that my order has attributes "attributes":[], then i get this error:
Invalid argument supplied for foreach()
and my data in json column is like:
"[{\"id\":29,\"name\":\"effewf\",\"price\":24524,\"quantity\":\"1\",\"attributes\":[{\"attr\":{\"label\":\"Red\",\"price\":\"5000.00\"}},{\"attr\":{\"label\":\"22\\\"\",\"price\":\"900000.00\"}}],\"conditions\":[]}]"
as you see this order has 2 attributes. (can be more or less).
additional
this is how i get those data in order model:
protected $casts = [
'product_data' => 'array',
];
any idea why i get that error and how i can get my attributes data no matter if my order has attribute or not?
UPDATE
if i open edit page of order without attribute and dd the result will be like:
array:6 [▼
"id" => 27
"name" => "new product"
"price" => 7246
"quantity" => "1"
"attributes" => []
"conditions" => []
]
if load the same on order with attributes get the error above.
You should only allow to print data if exists and having the format we are expecting ,please add necessary conditions to your code like below which may prevent from getting the errors
Assuming the array you have in post is data you need to print.
#if($order->product_data) // check product_data value or not , also add key exists if needed
#if(is_array($order->product_data)) // check for product_data is array or not
#foreach($order->product_data as $data)
{{ $data['quantity'] // if array }}
{{ $data->quantity // if object }}
#if($data->attributes)
#foreach($data->attributes as $attribute) // loop through attributes
{{ $attribute->nameOfTheProperty // if object }}
#endforeach
#endif
#endforeach
#endif
#endif
But better to handle the data in controller if possible
update:
you need to convert your data into array, as your attribute property will be blank array if not having value otherwise it will be stdObject.
so your code should be : ($order->product_data should be an array if not then convert it to an array)
#if($order->product_data)
#if(is_array($order->product_data)) // assuming array
#foreach($order->product_data as $data)
{{ $data['quantity'] // if array }}
#if(count($data['attributes']) > 0) // **checked for blank array**
#foreach($data->attributes as $attribute) // loop through attributes
{{ $attribute['attr']['label'] }}
{{ $attribute['attr']['price'] }}
#endforeach
#endif
#endforeach
#endif
#endif
Tried with your sample data, and that executed without any error.
$json = "[{\"id\":29,\"name\":\"effewf\",\"price\":24524,\"quantity\":\"1\",\"attributes\":[{\"attr\":{\"label\":\"Red\",\"price\":\"5000.00\"}},{\"attr\":{\"label\":\"22\\\"\",\"price\":\"900000.00\"}}],\"conditions\":[]}]";
$jsonAsArray = json_decode($json, true);
foreach ($jsonAsArray as $data) {
echo $data['quantity'] . "\n";
if (! empty($data['attributes']) ) {
if (is_array($data['attributes'])) {
foreach ($data['attributes'] as $attribute) {
echo $attribute['attr']['label'] . ' ' . $attribute['attr']['price'] . "\n";
}
}
}
}
Outputs:
1
Red 5000.00
22" 900000.00
In your case, the product_data is not cast as an array.
You could try Defining An Accessor in your Order model, and remove the cast property of product_data
public function getProductDataAttribute($value)
{
return json_decode($value, TRUE);
}
Or Manually decode the json in your loop
#foreach (json_decode($order->product_data, TRUE) as $data)
{{ $data['quantity'] }}
#if (! empty($data['attributes']))
#foreach ($data['attributes'] as $attribute)
{{ $attribute['attr']['label'] }} {{ $attribute['attr']['price'] }}
#endforeach
#endif
#endforeach
This is how I did mine (category is a json column in the DB):
<div class="category">
<ul class="list-group">
#foreach ( json_decode( $code->category ) as $category)
<li class="list-group-item d-flex justify-content-between align-items-center">
<span class="badge badge-secondary badge-pill">{{$category}}</span>
</li>
#endforeach
</ul>
</div>
You just have to json_decode your json column to get an array and iterate over it. that's it, cheers.
I have 5 columns in my database. Here are the names of the columns:
promo1
promo2
promo3
promo4
promo5
I would like to combine these columns to be able to make a foreach in my view.
I tried this:
$promos = Building::select('promo1', 'promo2', 'promo3', 'promo4', 'promo5')->where('id', $card->id)->get()->toArray();
and in my view :
#foreach($promos as $promo)
<span>{{ $promo['promo1'] }}</span>
#endforeach
But I have only one result for my foreach. Instead of 5. And I can only select one by one ($ promo ['promo1'], $ promo ['promo2']) so doing a foreach would not help
Is there a way to do that? thank you very much
When you're using get() method, you're getting a collection. Use the find() method to get an object instead of collection:
$promos = Building::select('promo1', 'promo2', 'promo3', 'promo4', 'promo5')->find($card->id)->toArray();
Then you'll be able to iterate over promos:
#foreach ($promos as $promo)
<span>{{ $promo }}</span>
#endforeach
First get the building object
$building = Building::select('promo1', 'promo2', 'promo3', 'promo4', 'promo5')->findOrFail($card->id);
then loop through the promos
#foreach ($building->getAttributes() as $key => $value)
<span>{{ $key }} : {{ $value }}</span>
#endforeach
note: using the $key here is optional
I have the following foreach loop that I'm getting good results with however when it gets to the elseif statement I'm attempting to see if two of the players are on the same team or not and if they are then have them listed together separated with a & symbol. Currently I am getting the following still.
Player 1 vs. Player 2 vs. Player 3 vs. Player 4
This is okay however Player 1 and Player 2 are on the same team. So its not seeing them as on the same team for some reason. Does someone see what my issue is?
#foreach ($match->players AS $key => $player)
#foreach ($player->list as $member)
{{ $member->player_name }}
#endforeach
#if($match->players->count() - 1 != $key)
vs.
#elseif ($match->players[$key - 1]->team_id == $player->team_id)
&
#endif
#endforeach
EDIT: I changed the data a little but still should work.

It was tricky to puzzle together your $match variable :)
#if($match->players->count() - 1 != $key)
Your $match->players->count() is always equal to the value of the number of players(say 'n'). So your 'if' ONLY checks the 'n-1' != current key ($key). [Which is true except for the last key, so you get all 'vs'].
This should work:
#foreach ($match->players AS $key => $player)
#foreach ($player->list as $member)
{{ $member->player_name }}
#endforeach
#if($player->team_id != $match->players[$key + 1]->team_id)
vs.
#elseif ($player->team_id == $match->players[$key + 1]->team_id)
&
#endif
#endforeach
In this we are checking if the current player's team is the same as the next player's team [$key+1].
Note:
You need to stop the loop for the last player, since $key+1 will go outside your array and you will get an offset error.
Therefore add another if:
#foreach ($match->players AS $key => $player)
#foreach ($player->list as $member)
{{ $member->player_name }}
#endforeach
#if($key + 1 < $match->players->count())
#if($player->team_id != $match->players[$key + 1]->team_id)
vs.
#elseif ($player->team_id == $match->players[$key + 1]->team_id)
&
#endif
#endif
#endforeach
