Hi , this PHP code send me all the checkboxes and not the checked by the user

    $checkboxValues = [];
    
    foreach ($_POST as $key => $value) {
        // Verifica si el campo es un checkbox y si está marcado
        if (strpos($key, 'baños_opcion') === 0 && isset($_POST[$key])) {
            $checkboxValues[] = $_POST[$key];
        }
    }
}

$toilette = implode(", ", $checkboxValues);

$sql = "INSERT INTO wp_form_submissions (nombre, apellido, email, observaciones, resultado, toilette)
        VALUES ('$nombre', '$apellido', '$email', '$observaciones', '$resultado', '$toilette')";

my html

  <input type ="hidden" name="baños_opcion6" value="ninguno: 0m"/>
  <input type="checkbox"  name="baños_opcion6[]" value="0" />
  
  <input type ="hidden" name="baños_opcion7" value="toilette: 2.10m"/>
  <input type="checkbox" name="baños_opcion7"  value="2.10" />
  
  <input type ="hidden" name="baños_opcion8" value="simple: 4.32m"/>
  <input type="checkbox" name="baños_opcion8" value="2.10" />
        
  <input type ="hidden" name="baños_opcion9" value="Antebaño: 8.46m"/>
  <input type="checkbox" name="baños_opcion9" value="8.46" />

Datos insertados correctamente en la base de datos.Valores de los campos de checkbox:

    Ideally, you shouldn’t be mixing in the hidden inputs like this, unless you really need them as they will cause issues like what you have encountered.

    The values you are getting in the loop are the hidden input values rather than the checkbox ones.
    Since you have the same input name, values will clash.

    However, based on the understanding that you need the hidden input’s value corresponding to the checkbox selected, you can try modifying the code as below.

    In the HTML separate the name attribute of the hidden inputs and checkboxes.

      <input type ="hidden" name="baños_opcion7" value="toilette: 2.10m"/>
  <input type="checkbox" name="baños_opcion_check_7"  value="2.10" />
  
  <input type ="hidden" name="baños_opcion8" value="simple: 4.32m"/>
  <input type="checkbox" name="baños_opcion_check_8" value="2.10" />
        
  <input type ="hidden" name="baños_opcion9" value="Antebaño: 8.46m"/>
  <input type="checkbox" name="baños_opcion_check_9" value="8.46" />

    For the PHP you can change as below

    $checkboxValues = [];

foreach ($_POST as $key => $value) {
    // Verifica si el campo es un checkbox y si está marcado
    if (strpos($key, 'baños_opcion_check_') === 0 && isset($_POST[$key])) {
        $input_key = str_replace("_check_","",$key);
        $checkboxValues[] = $_POST[$input_key];
    }
    }
}

$toilette = implode(", ", $checkboxValues);

$sql = "INSERT INTO wp_form_submissions (nombre, apellido, email, observaciones, resultado, toilette)
        VALUES ('$nombre', '$apellido', '$email', '$observaciones', '$resultado', '$toilette')";

    In the PHP portion, the if condition was changed to identify the checkbox name only. As a second step the $input_key removes the _check_ to arrive at the name for the hidden input for the checkbox.

    Full PHP file for the working test

    <?php
$checkboxValues = [];
if (!empty($_POST)){
foreach ($_POST as $key => $value) {
    // Verifica si el campo es un checkbox y si está marcado
    if (strpos($key, 'baños_opcion_check_') === 0 && isset($_POST[$key])) {
        $input_key = str_replace("_check_","",$key);
        $checkboxValues[] = $_POST[$input_key];
    }
    }

    var_dump($checkboxValues);
    exit();
}

?>


<form method="POST">
      <input type ="hidden" name="baños_opcion6" value="ninguno: 0m"/>
      <input type="checkbox"  name="baños_opcion_check_6[]" value="0" />
      
      <input type ="hidden" name="baños_opcion7" value="toilette: 2.10m"/>
      <input type="checkbox" name="baños_opcion_check_7"  value="2.10" />
      
      <input type ="hidden" name="baños_opcion8" value="simple: 4.32m"/>
      <input type="checkbox" name="baños_opcion_check_8" value="2.10" />
            
      <input type ="hidden" name="baños_opcion9" value="Antebaño: 8.46m"/>
      <input type="checkbox" name="baños_opcion_check_9" value="8.46" />
      <button type="submit">Submit</button>
</form>

    Issue is that you are using the same name attribute for both hidden inputs and check boxes. To get only the checked check boxes, you should give unique name attributes to each checkbox.

    HTML:

    <form method="post" action="action.php">
    <input type="hidden" name="baños_opcion6_desc" value="ninguno: 0m" />
    <input type="checkbox" name="baños_opcion6" value="0" />

    <input type="hidden" name="baños_opcion7_desc" value="toilette: 2.10m" />
    <input type="checkbox" name="baños_opcion7" value="2.10" />

    <input type="hidden" name="baños_opcion8_desc" value="simple: 4.32m" />
    <input type="checkbox" name="baños_opcion8" value="4.32" />

    <input type="hidden" name="baños_opcion9_desc" value="Antebaño: 8.46m" />
    <input type="checkbox" name="baños_opcion9" value="8.46" />
<input type="submit" value="Submit" />

    PHP:

    $checkboxValues = [];

foreach ($_POST as $key => $value) {
    // Check if the field is a checkbox and if it's checked
    if (isset($_POST[$key . '_desc'])) {
        $checkboxValues[] = $_POST[$key];
    }
}

$toilette = implode(", ", $checkboxValues);

print_r($toilette);

    This should work as expected!
