I'll go through every page here for an analysis and know how to send the value of the input type to the other page. Thank you!

                            echo '<td>' .  $cor . '</td>';
                            echo '<td>' .  $numeracao . '</td>';

                            echo '</tr>';

echo'<td height="10"><a href="carrinho_vitrine.php?acao=add&id='.$id.'">

 //fechando a conexão
 $pdo = null;
               }
catch(PDOExcception $erro){
echo $erro->getmessage();
                          }
}
?>  

</table> 

Sua numeração:
<input type="text" value="" id="numero" maxlength="2" placeholder="Digite" size="3" align="center">

</form> 

</body>
</html>

With jquery I'm testing and I'm capturing the value of the input type. 

  $(document).ready(function(){ 

   $("#add_car_vitrine").click(function(){

     var valor = $("input[name=numero]").val();

       if($("#numero").val()==""){ 
         alert("Digite sua numeração!");
         return false; 
       }                
       //mostramos o valor com alert()
       //alert(valor);
   });
});

How can I mount an Ajax and send the value of this input type to the other page? Can someone post an example for kindness? Thankful.

Since the question was edited, the answer was also edited and becomes:

  • This line can not be within if(isset($_POST['cbo_vitrine'])){ because it will not appear to be clicked: 

    <img src="img/comprar-1.png" name="add_car_vitrine" id="add_car_vitrine" height="50" width="120" align="center" title="Adicionar ao Carrinho" value="add_car_vitrine"></a></td>';

  • To be functional put it before the closing tag </form> as button : 

    ..........
..........
<?php
echo'<td height="10"><button type="button" id="add_car_vitrine">
<img src="img/comprar-1.png" height="50" width="120" align="center" title="Adicionar ao Carrinho"></button></td>';
?>
</form>

  • Place an id in the tag form example: id="myForm" 

    <form id="myForm" action="carrinho_vitrine.php" method="post">

  • The script - in the else place the submission of the form $('#myForm').submit(); 

    $(document).ready(function(){ 

    $("#add_car_vitrine").click(function(){

    var valor = $("input[name=numero]").val();

      if($("#numero").val()==""){ 
         alert("Digite sua numeraçao!");
         return false; 
      }else{
         $('#myForm').submit();
      }                 
      //mostramos o valor com alert()
      //alert(valor);
   });
});

    I do not know if I understand your question. Where did you put this echo? If it is in form, its expression may look like this: 

    <form method="post" action="teste.php?pag=<?php echo $pag; ?>">
...
