I have a panel survey manager where I add, edit and delete dimensions and questions of the survey, through this the survey that contains 4 dimensions, in a total of 21 questions and with a likert scale, is applied.

My problem is based on placing a counter so that the name of each radio button is different I will attach an example:

The question 1 name="likert1" , the question 2 name="likert2" and so on Question 21 name="likert 21" .

I enclose the code where I make the consultations

<?php
    require 'conexion.php';
     mysqli_query($mysqli,"SET NAMES 'utf8'");

  ?>



  <html lang="es">

  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1">

      <?php
        $sql = "SELECT * FROM dimension";
        $resultado = $mysqli->query($sql);

        foreach($resultado as $row){


        ?>


        <div class="row table-responsive">

Put your variable $ likert before the first for and start at 1

$likert=1;
foreach($resultado as $row){

modify the line that defines the name in all its cases (does not apply, my disagreement etc):

<center><input type="radio" name='<?php echo "likert".$likert; ?>'

It's all.

If you want all the radios to be called likert + number of the sequence, starting with 1:

You have to modify the value of the initial variable, setting it to 1:

$likert=1;

You have to move it from place, placing it outside the loop for

$likert=1;

foreach($resultadoP as $row){
      // $likert=0; borrar esto

      //resto del código

Then, to each line you apply something like this:

name='<?php echo "likert".$likert; ?>'

Example, in the case of not applicable:

<center><input type="radio" name='<?php echo "likert".$likert; ?>' value="no aplica"></center>

And so with everyone else.

You have to move the increment of $likert to be inside the loop, that way it will increase in each iteration.

    $likert++;
<?php }
