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

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.
1

I have a table column which is separate with comma. Column name is 'Intro' and the values are:
Rumi, school,2018,lecturer
I need to show this comma separated value one by one. The output should be like this :
Rumi
I tried this code in my blade file :
#foreach ($evaluation as $client)
#foreach (explode(',', $client->Intro) as $client_intro)
{{ $client_intro[0]}}
#endforeach
#endforeach
but this shows nothing. what is the problem ?
Just simply remove the index
{{ $client_intro[0]}} ---->> should be --> {{ $client_intro}}
Try This:
#foreach ($evaluation as $client)
#foreach (explode(',', $client->Intro) as $client_intro)
{{ $client_intro }}
#endforeach
#endforeach
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 )
{{ $next }}
#endforeach
I have json column where i save my orders data in it, code below is sample of that data:
[{"id":27,"name":"new product","price":7246,"quantity":"1","attributes":[],"conditions":[]}]
with code above if i have such loop in my edit page i'm able to get orders info:
#foreach($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.
For example, in PHP a way to parse RSS feed could be:
<?php
$rss = simplexml_load_file('http://blog.wordpress_site.com/feed/');
{{ rss }}
foreach ($rss->channel->item as $item) {
echo $item->title;
echo $item->link;
echo $item->description;
echo $item->guid;
}
?>
How can I have this on Twig?
UPDATE: Thanks to the reply I got it. Now it gets this by item but not some fields like image, category or text of the post:
SimpleXMLElement {#955 ▼
+"title": "Website. Description of the website"
+"link": "http://blog.website.com/liktothepost"
+"pubDate": "Fri, 17 Feb 2017 07:56:43 +0000"
+"category": SimpleXMLElement {#1131}
+"guid": "http://blog.website.com/?p=400"
+"description": SimpleXMLElement {#953}
}
You would create a controller with an action to pass the object to your Twig file that you want to render like so:
public function viewRSSAction(Request $request){
$rss = simplexml_load_file('http://blog.wordpress_site.com/feed/');
return $this->render('my_rss.html.twig', array(
'rss' => $rss,
));
}
Then your my_rss.html.twig might look like this:
{% for item in rss %}
{{ item.title }}
{{ item.link }}
{{ item.description }}
{{ item.guid }}
{% endfor %}
