How can i get a dropdown to select whatever id is present within the database.
I have a user's table that has a location_id and a towns table that has town_id and town_name so I want the dropdown to know what the user table location_id is and show the town_name based on the id.
How can this be done in Laravel?
Thanks in advance.
What you would do is assign your user and towns to the view. Next loop your towns table to generate your select list. Something like:
<select name="location">
#foreach($towns as $town)
<option value="{{ $town->id }}" {{ ($user->location_id == $town_id) ? "selected" : "" }}>{{ $town->town_name }}</option>
#endforeach
</select>
Ok fixed it to match blade:
<select name="location" class="form-control">
# foreach($towns as $town)
<option value="{{ $town->town_id}}" #if ($user->location == $town->town_id) "selected" #else "" #endif>{{ $town->town }}</option>
#endforeach
</select>
But it's not showing the selected item
If you are sending correct data to the view and the problem is only repopulating the select then you may try this, just put this in your view and send $towns from your controller as you are sending now
{{ Form::select('towns', $towns, Input::old('towns')) }}
No need to manually loop through the array. Laravel's Form class will build the select/dropdown.
My last answer works, just find it was cached by the looks in the browser, so all fixed.

Hye,
I want to get dropdown selected data.
For your information, my dropdown data is from my database. I already retrieve data from database and put it inside my dropdown.
Right now, I want to make validation. If user key in all information and forgot to key in 1 column data, the dropdown part should get the previous selected data right? So here are my coding, I still can get the previous selected data.
<div>
<x-label for="pizzatype" :value="__('Choose pizza type:')" />
<select name="pizzatype" id="pizzatype">
<option selected disabled>Please choose</option>
#foreach ($pizzainfo as $pizzaitem)
<option value="{{ old('$pizzaitem->name') }}">{{ $pizzaitem->name }}</option>
#endforeach
</select>
</div>
All dropdown button should get the selected previous button...
As I understand the problem is that you are trying to get an old() value that does not exist...
the quick fix is :
<select name="pizzatype" id="pizzatype">
<option #if(!old('pizzatype')) selected #endif disabled>Please choose</option>
#foreach ($pizzainfo as $pizzaitem)
<option #if(old('pizzatype') == $pizzaitem->name) selected #endif value="{{ $pizzaitem->name }}">{{ $pizzaitem->name }}</option>
#endforeach
</select>
I have a select input that allows for multiple options to be selected. Because of the simple requirements, these selections are just stored as an array in my MySQL field. So for example they are stored as:
[Retail, Wholesale]
Now my question is, if I wanted the user to be able to edit the specific record, how would I pull the options up as selected in the select input?
The select field is as such:
<select class="form-control" name="type_industry">
<option value="Retail">Retail</option>
<option value="Wholesale">Wholesale</option>
<option value="Service">Service</option>
</select>
This is in a Laravel blade template, but if necessary I'm willing work with pure php answers or even javascript, I just need to be able to move past this issue.
Thanks!
You can use in_array() function,
<select class="form-control" name="type_industry">
<option value="Retail" #if(in_array("Retail", $selected_items_array)) selected #endif>Retail</option>
<option value="Wholesale" #if(in_array("Wholesale", $selected_items_array)) selected #endif>Wholesale</option>
<option value="Service" #if(in_array("Service", $selected_items_array)) selected #endif>Service</option>
</select>
if [Retail, Wholesale] is a php array ($savedOptions), and you have a list of all available options ($availableOptions) as another array, pass them to the blade view and in your blade just loop through:
#foreach ( $savedOptions as $value )
<option {{ in_array($value,$availableOptions) ? 'selected' : '' }} value={{ $value }}>{{ $value }}</option>
#endforeach
I am a newbie in laravel.
In my database, I have two tables, News(id, id_type) and Type(idtype,name). And in post News page, I use dropdown to select Type for my new news.
So, when I want to show the type name of this News, I do:
<div class="controls">
<select multiple name="Type">
#foreach($type as $type)
<option
#if($news->id_type == $type->idtype)
selected="selected"
#endif
value="{{$type->idtype}}">{{$type->name}}</option>
#endforeach
</select>
</div>
But I have wrong result for all type in Type tables.
Help me,please and thanks for your help!!
The single equals is for assignment while two equals is for comparison. Change this line to be
#if($news->id_type == $type->idtype)
The code block within #foreach can be modified to serve the purpose of selecting a news type corresponding to each news.
<select name="Type" id="Type" class="form-control">
#foreach($type AS $data)
<option value="{{ $data->idtype }}">{{ $data->name }}
</option>
#endforeach
</select>
The #if codeblock is not working as you think it is supposed to. So, better remove it.
Now if you want to get the type associated with each news then you can very well specify it in your Controller and get the news as per the type_id.
Code snippet from your Controller will be more helpful.
Using Laravel 5, I'm trying to make a list of countries in a dropdown.
I use this syntax :
$countries= Countries::get('name', 'id');
And then, with blade
{!! Form::select('countries', $countries) !!}
This gives me a nice list, but I would like to set a custom attribute on every country. This argument is the continent of the country, something like "data-continent='X'".
This continent is a column of my table "countries".
Add the continent column to your query
$countries= Countries::get('name', 'id', 'continent');
Then loop over the results and ouput using any format you prefer.
<select name="country">
#foreach ($countries as $c)
<option data-continent="{{ $c->continent }}" value="{{ $c->id }}">{{ $c->name }}</option>
#endforeach
</select>
I've a form to be completed to create a post. Now after creating that post, if I want to edit it, I'm showing a select option in the edit page something like below. (I am using Laravel)
<select name="posts">
#foreach($posts as $post)
<option value="{{$post->id}}"> {{$post->name }} </option>
#endforeach
</select>
Now I need to preselect the populated select field with the current post name. I have a post id in the URL which I can get know in which post I am in. How can I select the right option without making a duplicate of the same in the options field. ?
Assuming you pass the current post id into the template as $postId, you could do something like this:
<select name="posts">
#foreach($posts as $post)
<option value="{{$post->id}}" {{ ($post->id == $postId) ? 'selected="selected"' : '' }}> {{$post->name }} </option>
#endforeach
</select>
Also, since you're using Laravel, a little bit cleaner solution is to use Laravel's Form builder:
{{ Form::select('posts', $posts, $postId) }}
Use an if-else structure inside the loop.
if ( post is equal to the current post ) {
<option selected="selected" value="{{$post->id}}"> {{$post->name }} </option>
} else {
<option value="{{$post->id}}"> {{$post->name }} </option>
}
The condition depends on you, whether you want to use the post id or the post name to check. (Whatever you have available).
