I have a problem here with the pass-through when clicking on the submit was to pass to another php file, the values come from a php loop, I tested without the loop going ... more searching for the database of Wordpress bank is not going Do you have any suggestions?

  <script>
        total = 0;
        
        function adiciona(id)
        {
            calcula(id,"adicao");
        }
        
        function remove(id)
        {
            calcula(id,"subtracao");
        }    
            
        function calcula(id,operacao)
        {
                nomeid  = "nome"+id;
                precoid = "preco"+id;
                qtdid   = "qtd"+id;
                
                nome  = document.getElementById(nomeid).innerHTML;
                
                preco = document.getElementById(precoid).innerHTML;    
                preco = parseInt(preco);
                
                qtd   = document.getElementById(qtdid).innerHTML;
                qtd   = parseInt(qtd);

                //Debug
                //alert("Produto: " + nome + "\n Preço: " + preco);    
                
                if(operacao=="adicao")
                {
                    total = total + preco;
                    qtd = qtd + 1;
                }
                else
                {

        }

Doing a relationship update using REST, Jax-rs, Jersey and Javascript How to collect data from two queries in a php object?

score 0 · Answer 1

Dude I think I know what's going on.

Try the following, instead of using this_id () function, create a variable $ i starting from $ i = 1; and inside the loop you put $ i ++;

It will look like this:

<?php 
$i=1;   // $i começando com 1 aqui
if (have_posts()): while (have_posts()) : the_post();?>     

        <tr>
            <td class="prodtd">

                <div id="nome<?php echo $i; ?>"  class="nomeprod"> <?php the_title(); ?></div>

                <div id="preco<?php echo $i; ?>" class="preco"><?php echo get_post_meta( $post->ID, 'preco', true ); ?></div>

            </td>
            <td align="center" valign="middle">

                <input type="button" value="-" onclick="remove(<?php echo $i; ?>)"> 

                <span id="qtd<?php echo $i; ?>">0</span> 

                <input type="button" value="+" onclick="adiciona(<?php echo $i; ?>)">

            </td>
        </tr>

<?php $i++; ?>


<?php endwhile; else:?>
<?php endif;?>

Explanation: Your javascript is looking for these "ids" and trusting they are sequential (I know this because I helped with this code in another question of yours, hahaha). But they only serve to help collect the data on the page, it does not have to be bank ids, as is what is happening there. Please check it and see if it does.
