I'm stucked on the 4th step on one page checkout, I can't continue to next step on shipping to payment.

The button reacts, ajax call is fine, returned content seems perfect, but it doesn't execute or fill on HTML.

I was read about that issue on more topics like the following:

But no success. I also read and try another posts, but the same result.

The problem is that when I click continue on shipping information, the payment is not loaded but ajax request do.

JSON returns the following:

"goto_section": "payment",
"update_section": {
    "name": "payment_method",
    "html": '<dt id="dt_method_cashondelivery">            <input id="p_method_cashondelivery" value="cashondelivery" type="radio" name="payment[method]" title="Contrarreembolso" onclick="payment.switchMethod('cashondelivery')" class="radio" />            <label for="p_method_cashondelivery">Contrarreembolso </label>    </dt>        <dt id="dt_method_purchaseorder">            <input id="p_method_purchaseorder" value="purchaseorder" type="radio" name="payment[method]" title="Purchase Order" onclick="payment.switchMethod('purchaseorder')" class="radio" />            <label for="p_method_purchaseorder">Purchase Order </label>    </dt>        <dd id="dd_method_purchaseorder">        <ul class="form-list" id="payment_form_purchaseorder" style="display:none;">    <li>        <label for="po_number" class="required"><em>*</em>Número de la orden de compra</label>        <div class="input-box">            <input type="text" id="po_number" name="payment[po_number]" title="Número de la orden de compra" class="input-text required-entry" value="" />        </div>    </li></ul>    </dd>    <script type="text/javascript">    //<![CDATA[        payment.init();        //]]></script>'

Seems that payment.init() doesn't execute never because it doesn't enter on debugger on that function, but if I execute payment.init() manually on console the result is the same even entering on the javascript function successfully.

Doesn't matter if I change checkout.xml, info.phtml, methods.phtml, and more files, the problem is the same (all seems correct, no errors, good information retrieving but not success on step change).

If I change to the default template, the error persists, but the right column with the order resume updates correctly, when if I configure my custom template it doesn't, but the step to request payment information is always unaccessible.

Please, can you put some light on this?

Thank you.


I can add more information. On /var/log/exceptions.log I can see:

But I don't know what and why the block is invalid, so shipping loads fine and also payment json.


Note that the payment information loads fine, if I remove display: none from <div id="checkout-step-payment"> I can see all options and fine, so I guess there is a problem on the javascript that show this part of the page.


I add an answer and will be accepted today, but if someone has a better solution I will accept it as the correct answer.

Ok, I solve the problem. It was a javascript problem, not a php or block problem.

On the file opcheckout.js we can found this piece of code (line 650 aprox)

    if (response.update_section) {

But the problem is that $('checkout-'+response.update_section.name+'-load') element doesn't exists, because response.update_section.name = "payment_method" where needs to be response.update_section.name = "payment-method" (semicolon).

I don't know why PHP returns payment_method instead of payment-method that is the correct element, or maybe is a problem on the Meigee Theme that I am using.

However, to avoid problems on php, I solve it on the javascript changing the above code for this piece:

    if (response.update_section) {
        var sect = (response.update_section.name === "payment_method") ? "payment-method" : response.update_section.name;

Only for payment-method and all is OK right now, I can complete the checkout process with no problem.

If you know another method to solve this problem, please, add an answer and it will be accepted.
