Pass multiple variables in laravel foreach loop [duplicate] - arrays

This question already has answers here:
Two arrays in foreach loop
(24 answers)
Closed 2 years ago.
So what I am trying to do is create an FAQ accordion but use a #foreach loop and not copy and paste the entire list. My controller code looks like this:
public function faq(){
$faqs=array(
'questions' => ['question1','question2','question3'],
'answers' => ['answer1','answer2','answer3'],
'counts' => ['One','Two','Three']
);
return view('frontend.pages.faq')->with($faqs);
}
This is what I wish to achieve:
#foreach($questions as $question && $answers as $answer && $counts as $count)
<div id="accordion">
<div class="card card--faq mb-2">
<div class="bdv-btn card-header" id="heading{{$count}}">
<h5 class="mb-0">
<a class="btn btn-link w-100" data-toggle="collapse" data-target="#collapse{{$count}}" aria-controls="collapse{{$count}}">
{{$question}}
</a>
</h5>
</div>
</div>
</div>
<div id="collapse{{$count}}" class="collapse" aria-labelledby="heading{{$count}}" data-parent="#accordion">
<div class="card-body bg-light">
{{$answer}}
</div>
</div>
</div>
#endforeach()
In case of the $counts variable the reason I am not using $key instead is that I wish to achieve One, Two, Three and not 1, 2, 3.
The code above is of course in correct. What would be the best way to achieve this? Is it even possible?

you cant access your faq variable in your blade like this, due the wrong usage of with. you should do this:
return view('frontend.page.faq')->with(['faqs'=>$faq]);
first of all do this in your controller:
public function faq(){
$faqs=array(
'questions' => ['question1','question2','question3'],
'answers' => ['answer1','answer2','answer3'],
'counts' => ['One','Two','Three']
);
return view(frontend.page.faq')->with(['faqs'=>$faqs]);
}
then in your blade you can access them like so:
#foreach($faqs['questions'] as $question)
{{dd($question)}}
#endforeach
now you have your faqs in your blade

Dynamically access image in react

I am importing an image to use later like so
import S1 from '../../assets/images/S1.svg';
I am then mapping through an array and want to access this import dynamically. How can I do this successfully?
loop is here:
{characteristics.map(characteristic => (
<div className="characteristic" key={characteristic.key}>
<span className="characteristicKey"><img src={characteristic.key} alt={characteristic.label} /></span>
<span className="characteristicLabel">{characteristic.label}</span>
</div>
))}
You can give a related name to file with characteristics for example c1.svg , c2.svg , c3.svg ...
then in your map :
{characteristics.map((characteristic,i) => (
<div className="characteristic" key={characteristic.key}>
<span className="characteristicKey"><img src={require("c"+i+1+".svg")} alt={characteristic.label} /></span>
<span className="characteristicLabel">{characteristic.label}</span>
</div>
))}

How to search strings inside Array of arrays using eloquent

So I have a databse column where the content is an Array like this:
[{"tag_name":"example1"},{"tag_name":"example2"}, {"tag_name":"example3"}]
What I am trying to do is to retrieve videos with a certain tag. All the videopages have specific tags, and when a user clicks one of those tags, it is redirected to a view where similar videos with the same tag will be displayed.
Right now I have the following controller:
public function search($tag){
$tag = urldecode($tag);
$videos = Video::where('tags', 'LIKE', $tag)->paginate(12);
$settings = Detail::find(1);
$ads = Ad::find(1);
return view('search', ['videos' => $videos, 'settings' => $settings, 'ads' => $ads]);
}
And I have the following view (search.blade.php):
#foreach($videos as $video)
<div class="col-lg-4 col-xs-12">
<div class="row justify-content-center">
<img class="articleImg" src="{{$video->imgurl}}">
</div>
<div>
<p class="float-left">{{$title = substr($video->title, 0, 30) . " ..."}}</p>
<small class="duration float-right">{{$video->duration}}</small>
<div class="progress float-right">
<div class="progress-bar bg-success" role="progressbar" style="width: {{$video->rating}}%" aria-valuenow="{{$video->rating}}" aria-valuemin="0" aria-valuemax="100"></div>
</div>
</div>
</div>
#endforeach
The problem is that right now, no videos are shown in my view, even tough i get no errors at all. Is it because the columns has an array of arrays?
I assume it's because your controller is returning 0 videos because tag never match.
You are using LIKE statement without escaping your tag variables with %, so you are looking to match something that is exactly like tag, and because you have an array of tags as a column that will never happen.
One solution you could implement is changing your tag to something like this:
public function search($tag){
$tag = urldecode($tag);
$videos = Video::where('tags', 'LIKE', '%'.$tag.'%')->paginate(12);
$settings = Detail::find(1);
$ads = Ad::find(1);
return view('search', ['videos' => $videos, 'settings' => $settings, 'ads' => $ads]);
}
Here you can read more about the LIKE operator :D

Cannot use object of type __PHP_Incomplete_Class as array. FatalErrorException

I've encountered this problem (
Cannot use object of type __PHP_Incomplete_Class as array
) while doing an e-commerce site using Laravel, I tried to get the name of the purchased products. My controller function is this
$orders=Auth::user()->orders;
$orders->transform(function($orders, $key) {
$orders->cart=unserialize($orders->cart);
return $orders;
});
return view('shop.profile', ['orders'=>$orders]);
The problem in the view code is this exact line {{$item['item']['name']}}, without it, i can see the quantity puchased, the price and anything else.
I've done everything I knew and found on the internet, but didn't find any solution
Based on your information, i would assume you could use a solution like this:
<h2 align="center">My orders</h2> <br/>
#foreach($orders as $order)
<div class="panel panel-default">
<div class="panel-body">
<ul class="list-group">
#foreach($order->cart->items as $item)
<li class="list-group-item">
<span class="badge">{{$item->price}} lei</span>
{{$item->item->name }} | {{$item->qty }}
</li>
#endforeach
</ul>
</div>
<div class="panel-footer"><strong>Total Price: {{$order->cart->totalPrice}} lei </strong></div>
</div>
#endforeach
Normally, you do not talk to the $items like an array, but like an object. I believe this should do the trick, please let me know if it worked :)

How to add item to array in ng-repeat with lazy loading

I have an array of comments. For each of the comment, I have a hidden form where you can reply. That item in each object of the array is called: comment.showSubCommentForm. When I click on Reply, I want to be able to reply with a comment and the function called: commentOnSubPost.
I load my data in chunks of 10 (lazy loading) which I am doing by using the infinite-scroll-distance Angular module. Every time I reach the end of the page, I get the next 10 items and add them to the $scope.comments array, which you can see below is what I am running my ng-repeat on .
The problem is that, although the commentOnSubPost works really well as in it adds the reply to the comment, I have reload the data so I can get the updated $scope.comments with the new reply. BUT - as I have implemented lazy loading, how do I do that if say I am on the 20th page?
I looked at some similar posts but their approach from mine was very different so am very lost.
My HTML:
<div infinite-scroll='loadMore()' infinite-scroll-distance='1'>
<div class="row">
<div ng-repeat="comment in comments track by $index">
<ul class="comments">
<li class="clearfix">
<a ng-href="#">SomeLink</a>
<div>
<p >{{ comment.date }} <a ng-href="/wall#/profile/main/{{ comment.userID }}">{{ comment.fullname }}</a> says <i class="commentReply"><a href ng-click="comment.showSubCommentForm = !comment.showSubCommentForm"><small>Reply</small></a></i></p>
<p class="mainComment">
{{ comment.comment }}
<p class="meta"><i class="showReply"><a href ng-click="comment.showReplies = !comment.showReplies"><small>Show Replies</small></a></i></p>
</p>
</div>
<div ng-show="comment.showSubCommentForm">
<form ng-submit="commentOnSubPost( post._id, comment._id, subComment)">
<div class="form-group">
<div class="form-group">
<textarea ng-model="subComment" class="form-control" placeholder="Reply to the above comment"></textarea>
</div>
<input type="submit" value="Reply">
</div>
</form>
<div ng-show="comment.showReplies" ng-repeat="subComment in comment.subComments track by $index">
<ul class="comments">
<li class="clearfix">
<a ng-href="/wall#/profile/main/{{ comment.userID }}"><img ng-src="{{ subComment.profilePic }}" class="avatar" style="border-radius: 50%"></a>
<div class="post-subComments">
<p class="meta">{{ subComment.date }}<a ng-href="SomeLink"> {{ subComment.fullname }}</a></p>
<p>
{{ subComment.comment }}
</p>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</div>
I won't add too much information here as I don't want to overload this post but if you need any particular information, please do let me know. I just need to know how do I reload the data (or not if there's another approach) so that I can get the latest data.
I hope this makes sense.
Thanks in advance!
Like you have $scope.comments = []; then on each call you just have to append upcoming data to this array.
Like $scope.comments = $scope.comments.concat(response.data);
In this way lazy loading will work.
I fixed this with making a Node route which gives back the exact comment I have just added. Then, I found that commentID in my $scope.comments and made it's subCommenemts to the one I have locally.
It does the job and the data is real. One drawback is that if at that time, there's another comment, it won't show up until the page's refreshed but I'm not too fussed about that.

how to update wordpress options from multi dimentional array

Im working on a theme for wordrpess where i want to add an option admin page for the theme settings. Cant get my brain to work with the process. heres my code:
$option_settings = (array(
array('Section1', array(
array( 'ID'=>'id_name1',
'Label'=>'Title1',
'Value'=>'The title1 bar',
'Desc'=>'Description Goes Here1',
'Type'=>'input_text',
'Button'=>'upload'
),
array('Section2', array(
array( 'ID'=>'id_name2',
'Label'=>'Title2',
'Value'=>'The title2 bar',
'Desc'=>'Description Goes Here2',
'Type'=>'input_text',
'Button'=>'upload'
),
))
));
if (!get_option('my_option_settings')) {
add_option('my_option_settings',$option_settings);
}
$options = get_option('my_option_settings');
if ($_REQUEST['save_settings']) {
//this is where my brain snaps huhu
}
echo '<form method="post" action="index.php" id="form_settings">';
echo '<p class="submit message"><input type="submit" value="Save Changes" name="save_settings" /></p>';
foreach ($options as $section) {
echo '<h3>'.$section[0].'</h3>';
foreach ($section[1] as $option => $value) {
switch($value['Type']) {
case "input_text":
echo '<p><strong>'.$value[Label].'</strong> <input type="text" name="'.$value['ID'].'" id="'.$value['ID'].'" value="'.$value['Value'].'" /></p>';
break;
}
}
echo '</form>';
my main concern here is how do i edit array inside an array and how to pass thru request. Any help is much appreciated Thanks in advance.
Updated question:
ok lets say that the $option-settings is the content of the options database from wordpress. The reason is i would like to have just 1 options in wordpress database and just store them thru array for more organize data.
first is get the value and assign it to a variable:
$fetchOption = get_option('my_option_settings');
now i will edit or update the array inside $fetchOption variable.
foreach ($options as $section) {
foreach ($section[1] as $option => $value) {
$value['Value'] = [$_POST[$value['ID']]];
}
}
Last is how to put back the changed value into the $fetchOption variable and update back the database using update_options('my_option_settings', $fetchOption).
Is this appropriate or not? whats the best practice for this? I could just assign them to 1 option but its kinda messy i guess. thanks again!
Uhm. I really hope you already found an answer, but..since someone could need this info I'd like to add it here.
First of all, the link to the resource.
Then, the answer I'm using as a "source":
As far WordPress is concerned - your multi-dimensional array is one option.
To update just part of the multi-dimensional array its necessary to retrieve the entire array, alter it accordingly and then update the entire array.
Suppose your multi-dimensional array is as follows:
my_options = array(
'option_a'=>'value_a',
'option_b'=>'value_b',
'inner_array'=>array(
'foo' => 'bar',
'hello' => 'world',
),
'option_c'=>'value_c'
)
And suppose you want to update the value of the 'hello' option from 'world' to 'moon'
//Get entire array
$my_options = get_option('my_options');
//Alter the options array appropriately
$my_options['inner_array']['hello'] = 'moon';
//Update entire array
update_option('my_options', $my_options);
Hope this helps Stackoverflow visitors in managing multidimensional arrays when it comes to Wordpress options :)
this example can help you;
<div class="ui grid">
<div class="four wide column">
<?php
if (isset($_POST)) {
if (isset($_POST['location']) && !empty($_POST['location'])) {
$locationArray = [];
// this line of code checks if the option is an array or not
$locationArray = is_array(get_option('book_location')) ? get_option('book_location') : [];
// In case of multidimentional array you can push array to an array
array_push($locationArray, $_POST['location']);
// print_r($locationArray);
update_option('book_location', $locationArray);
}
}
?>
</div>
<div class="eight wide column">
<form class="ui form" method="post">
<div class="red card">
<div class="content">
<!-- <div class="header">Bird Name</div>
<div class="meta">
<span class="category">location</span>
</div> -->
<div class="description">
<div class="field">
<label>Location</label>
<input type="text" name="location" placeholder="Location Name">
</div>
</div>
</div>
<div class="extra content">
<div class="ui divider"></div>
<div class="right floated author">
<button class="ui button" type="submit">Add Location</button>
</div>
</div>
</div>
</form>
</div>
<div class="four wide column">
</div>
</div>
