How to remove unwanted values from arrayed input? - php

Question

I just wanted to ask how can we avoid this kind of output from arrayed input. Every time I update it, these symbols ["\"[ keeps on multiplying. I'll show you the problem and the code below.
Thank you your future answers.
Route::resource('setups','SetupController');
public function index()
{
$data = DB::table('setups')->first();
if (!empty($data)) {
$socials = explode(',',$data -> social);
}else{
$socials = [];
}
return view ('adminpanel.setup.index',['data' => $data,'socials' => $socials]);
}
index.blade.php
<form action="{{ route('setups.edit',$data->id) }}">
<div class="row">
<div class="col-md-12" id="socialGroup">
#foreach($socials as $social)
<div class="form-group socialField">
<label class="bmd-label-floating">Social Links</label>
<input type="text" name="social[]" value="{{$social}}" class="form-control" disabled>
<i class="fa fa-plus"></i>
</div>
#endforeach
<div class="alert alert-danger" id="socialError">
<p><strong>Sorry! </strong>You've reached the max number for social links form.</p>
</div>
</div>
</div>
<form>
.
public function edit($id)
{
$data = DB::table('setups')->first();
$setup = DB::table('setups')->where('id', $id)->first();
if (!empty($data)) {
$socials = explode(',',$data -> social);
}else{
$socials = [];
}
if($setup){
return view ('adminpanel.setup.edit',['data' => $data,'socials' => $socials]);
}else{
return redirect('setups');
}
}
.
edit.blade.php
<form method="POST" action="{{ route('setups.update', $data->id) }}">
<div class="row">
<div class="col-md-12" id="socialGroup">
#foreach($socials as $social)
<div class="form-group socialField">
<label class="bmd-label-floating">Social Links</label>
<input type="text" name="social[]" value="{{ $social }}" class="form-control">
<i class="fa fa-plus"></i>
</div>
#endforeach
<div class="alert alert-danger" id="socialError">
<p><strong>Sorry! </strong>You've reached the max number for social links form.</p>
</div>
</div>
</div>
<form>
.
public function update(Request $request, Setup $setup)
{
$data = Input::except('_token', 'submit', '_method');
$tbl = decrypt($data['tbl']);
unset ($data['tbl']);
$data['updated_at'] = date('Y-m-d H:i:s');
DB::table($tbl)->where(key($data), reset($data))->update($data);
session::flash('message','Setup updated successfully!!!');
return redirect()->route('setups.index');
}
Solved! I just added this code in my SetupController#update to illuminate those unwanted divider or separator(whatever) before
sending to database.
if (Input::has('social')) {
$data['social'] = implode(',',$data['social']);
}

Answer 1

laravel escaped data by default. It was not giving any error,whenever
you retrieve data from database to throw in your blade view.Database
data escaping is good practice.
As you showed your data,there is some unwanted data.Before you attempt to save your data,you may trim($yourString) to remove unwanted white-space from start & end of a string.
And You must not let blank or empty string to view in your blade. So, you might use blank($var) to check whether it is blank or not?
<form method="POST" action="{{ route('setups.update', $data->id) }}">
<div class="row">
<div class="col-md-12" id="socialGroup">
#foreach($socials as $social)
#if(!blank($social))
<div class="form-group socialField">
<label class="bmd-label-floating">Social Links</label>
<input type="text" name="social[]" value="{{ $social }}" class="form-control">
<i class="fa fa-plus"></i>
</div>
#endif
#endforeach
<div class="alert alert-danger" id="socialError">
<p><strong>Sorry! </strong>You've reached the max number for social links form.</p>
</div>
</div>
</div>
