Extra whitespaces in blade statements. Laravel 8 - laravel

Question

The problem is, it's not just one variable, but statements with #if, #isset and #foreach directives. I can't remove whitespaces without syntax error. And all these whitespaces are displaying in input fields.
In description field I did this:
Check, if old('description') exists.
If yes, display it.
If not, then check, if variable $post exists (I use this form for store and update methods both).
If yes, display it.
If not, the field remains empty.
<div class="form-group">
<label for="description">Description</label>
<textarea id="description" name="description" rows="3">#if(old('description')){{ old('description') }}#else #isset ($post){{$post->description}}#endisset #endif</textarea>
<div class="form-group">
<label for="tags">Tags</label>
<input type="text" name="tags" id="tags"
value="#isset ($post, $tags)#foreach($post->tagged as $tagged){{$tagged->tag_name}},#endforeach #endisset">
I tried package hedronium/spaceless-blade, but it doesn't work with input values.

Answer 1

>#if and "#isset will be parsed as string because # will be parsed as syntax only if not join together with other character except space, new line or tab. You can do if condition without # inside {{}}.
I have a better solution using ternary operator and null coalescing operator.
change your long code
#if(old('description')){{ old('description') }}#else #isset ($post){{$post->description}}#endisset #endif
to
{{old('description') ?? isset($post)?$post->description:''}}
and change
#isset ($post, $tags)#foreach($post->tagged as $tagged){{$tagged->tag_name}},#endforeach #endisset
to
{{isset($post) ? implode(', ', $post->tagged->pluck('tag_name')->toArray() )):''}}
so the full code:
<div class="form-group">
<label for="description">Description</label>
<textarea id="description" name="description" rows="3">{{old('description') ?? isset($post)?$post->description:''}}</textarea>
</div>
<div class="form-group">
<label for="tags">Tags</label>
<input type="text" name="tags" id="tags"
value="{{isset($post) ? implode(', ', $post->tagged->pluck('tag_name')->toArray() )):''}}">
</div>

Answer 2

I solved my problem, using directive #php.
<textarea id="description" name="description" rows="3">#php
if(old('description')) {
echo old('description');
} elseif (isset($post)){
echo $post->description;
}
#endphp</textarea>
No more extra whitespaces.
