How to upload data more than once using Laravel - php

Question

I'm trying to make a system where an admin creates a project template, and then templates for both text (limit on characters) and images (height/width and file extension)
When I have one template, the code works perfectly and I can even upload multiple texts/images with just one template.
But the problem comes when I create a 2nd text/image template, the template by itself is created without a problem, but when I want to upload something using that template, well...
With the problem being in this part of the code:
Here are the full codes:
Creation of the templates:
Textos_DescripcionController.php (controller of the text template) :
public function store(Request $request){
$request->validate([
'nombre_texto' => ['required'],
'min' => ['required'],
'max' => ['required'],
]);
Textos_Descripcion::create($request->all());
$data_txt = DB::table('textos__descripcions')
->max('id');
$data_proyecto = $_POST['proyecto_id'];
//dd($data_proyecto);
Textos_Descripcion_Plantillas::insert(['proyecto_id' => $data_proyecto, 'texto_descripcion_id' => $data_txt]);
return redirect('/profile/' . auth()->user()->id);
}
TextosController.php (texts by themselves):
public function store(Request $request){
$plantilla_id = $_POST['id_descr'];
//Obtenemos ancho y alto de la plantilla
$min = DB::table('textos__descripcions')
->select('min')
->where('id' , '=', $plantilla_id)
->first();
$min_valor = $min->min;
$max = DB::table('textos__descripcions')
->select('max')
->where('id' , '=', $plantilla_id)
->first();
$max_valor = $max->max;
//ahora obtenemos los ancho y alto de la imagen
$largo = strlen($_POST["texto"]);
//ahora comparamos
if($min_valor > $largo || $max_valor < $largo){
echo "El texto no cumple con los estandares, la imagen debe ser desde " . $min->min . " hasta " . $max->max . "y tu texto tiene " . $largo . " caracteres ";
dd($largo);
return redirect('/profile/' . auth()->user()->id);
};
$paro = "Aqui toy";
echo "Succes, La imagen cumple con los estandares, la imagen debe ser desde " . $min->min . " hasta " . $max->max . "y tu texto tiene " . $largo . " caracteres ";
$request->validate([
'caption' => ['required'],
'texto' => ['required'],
'id_descr' => ['required'],
]);
//dd($paro);
Textos::create($request->all()); //
//Datos a tabla intermedia
$data_img = DB::table('textos__descripcion__plantillas')
->select('id')
->where('id' ,'=', $plantilla_id)
->first();
$data_img_valor = $data_img->id;
$id_proyecto = DB::table('proyectos')
->select('id')
->where('id','=', $data_img_valor)
->first();
$id_proyecto_valor = $id_proyecto->id; //I'm getting problems here
$id_txt = DB::table('textos')
->max('id');
Textos_Proyectos::insert(['proyectos_id' => $id_proyecto_valor , 'textos_id' => $id_txt]);
return redirect('/profile/' . auth()->user()->id);
}
I used a dd() right before the line of code that gives me problems, which gave a null. And to me this doesn't make sense, because it works with the 1st template, when I use the dd() I get the id of what I'm uploading:
Why is this happening?
I apologize is the question is too vague, if it lacks details please point it out
EDIT: I decided to change the first() to get() in the line that's throwing me problems, and I got an empty array
