Because my question is if it is possible, I have this code from a form that collects data and since all the values are assigned less in the textarea, check that the variable is not empty.
$eq_vehiculo = $equipamiento;
echo "<script>alert('$eq_vehiculo')</script>";
<textarea name="text_equipamiento" style="height:150px" placeholder="Ingrese detalles del vehiculo" value="<?php echo $eq_vehiculo; ?>" required></textarea>
