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 have those columns in my database table :
value_day_1 | value_day_2| value_day_3 |......|value_day_36
I'm trying to display each value in a view using a for loop
#for ($n=1;$n<37;n++)
{{ $day->value_day_? }}
#endfor
How can i replace the ? by $n ?
One solution would be
#foreach(range(1,37) as $n)
#php($column = 'value_day_' . $n;)
{{ $day->$column }}
#endforeach
I prefer to use range instead of the for syntax but it is not neccessary for your problem
#for ($n=1;$n<37;n++)
$d='value_day_'.$n;
{{ $day->$d }}
#endfor
Just assign to a new variable before
You can do this easily inline:
$day->{'value_day_'. $n}
I have json column where i save my orders data in it, code below is sample of that data:
[{"id":27,"name":"new product","price":7246,"quantity":"1","attributes":[],"conditions":[]}]
with code above if i have such loop in my edit page i'm able to get orders info:
#foreach($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 $key here is optional
I am displaying elements of an array #foreach($tags as $tag)$tag->#endforeach. The output is tag1tag2tag3. What is the possible way to sho elements of array in tag1,tag2,tag3. And how to not show, if there is only one element in array.
The selected answer is too complicated. Laravel has a simpler solution:
{{ $items->pluck('tag')->implode(', ') }}
implode() is good for echoing simple data. In real project you usually want to add some HTML or logic into the loop, use $loop variable which is available since 5.3:
#foreach ($arrayOrCollection as $value)
{{ $loop->first ? '' : ', ' }}
<span class="nice">{{ $value->first_name }}</span>
#endforeach
Use this. We can implement it using $loop->last
#foreach ($arrayOrCollection as $value)
<span class="nice">
{{ $value->first_name }}
#if( !$loop->last)
,
#endif
</span>
#endforeach
Use implode:
{{ implode(', ', $tags) }}
implode is one option or you can using join as well like this
{{ join(', ', $tags) }}
Try the first one or this one..
good luck
I believe what you are looking for might be something like this:
//have your array in php tags
//$arr = ['one', 'two', 'three']; ? >
//go through the array with foreach and if the count of the array is not equal to the las element then put coma after it
#foreach ($arr as $key => $value)
#if( count( $arr ) != $key + 1 )
{{ $value }},
#else
{{ $value }}
#endif
#endforeach
Try implode():
$arr = ['one', 'two', 'three'];
echo implode(',', $arr);
// output
one,two,three
I have a problem and I can't resolve it, please help me. So I have my form :
{{ Form::open(array('url'=>'/administration/student/addMarks','method' => 'post')) }}
#foreach($aObjectsInGroupe as $object)
{{ Form::hidden('id_object[]',$object->id) }}
{{ Form::label($object->name) }}
{{ Form::select('note[]', $aMarks, null, array('class'=>'form-control')) }}
<br />
#endforeach
{{ Form::hidden('id',$aOneStudent['id']) }}
{{ Form::submit('Add mark',array('class'=>'btn btn-primary')) }}
{{ Form::close() }}
In my StudentController I have a method for get the mark from student_id and object_id:
public function getMarkByStudentAndObject($nIdStudent, $nIdObject){
$aMark = \Mark::where('student_id', '=', $nIdStudent)
->and('object_id', $nIdObject)
->get()
->toArray();
}
$aMarsks it's a table :
$aMarks = array(
'0'=>'0',
'1'=>'1',
'2'=>'2',
'3'=>'3',
'4'=>'4',
'5'=>'5',
'6'=>'6',
'7'=>'7',
'8'=>'8',
'9'=>'9',
'10'=>'10',
);
It's possible to call the method getMarkByStudentAndObject in :
{{ Form::select('note[]', $aMarks, null, array('class'=>'form-control')) }}
to get the selected value?
Help me please. Thx in advance.
maybe you need to do this:
<select name="note[]" class="form-control">
#foreach($aMarks as $key => $value)
<option value="{{ $key }}">{{ $value }}</option>
#endforeach
</select>
You should also check your Eloquent query, instead of ->and use another ->where
Try the lists() function of the Query Builder
\Mark::where('student_id', '=', $nIdStudent)
->and('object_id', $nIdObject)
->lists('column_1', 'column_2');
You then get the values of column_1 as the keys of the array and column_2 as the values.
http://laravel.com/docs/4.2/queries#selects
You should be able to directly call this from the Form::select. A call to
Mark::getMarkByStudentAndObject($aOneStudent['id'], $object->id)->note
would give you the Mark object and then you would need to get the note column which stores the value in the Mark object. Resulting in a call like this:
{{
Form::select(
'note[]',
$aMarks,
Mark::getMarkByStudentAndObject(
$aOneStudent['id'],
$object->id
)->note, array('class'=>'form-control')
)
}}
At the moment I can't verify if this is working because I have no possibility to test it but it should work as Blade is just a wrapper for PHP calls.
