I'm working with an embedded app on our dev site and when I click the submit button inside the iframe, I am triggering a manual submission event on another form (not in an iframe) on that page. If I manually click the submit button for the form, my data posts and everything works correctly. However, I want to eliminate an extra user click and submit the external form automatically when a user submits the other form inside the iframe.
I've got everything working correctly on a base level. When a user clicks the submit button in the iframe, I am using JQuery to grab values from inside the iframe and set values in this external form. Using the jquery 'submit()' event, I am then able to submit that external form. The problem is, the page refreshes and the data doesn't go anywhere. If I remove the 'submit()' event and manually click the submit button, the form posts and in this case, adds a product with custom data to the product cart.
As a proof of concept, this is my 'iframed' HTML.
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1>Proof of Concept</h1>
<p>Total cost: $<span id="cust_price">222.22</span> plus shipping.</p>
<p>Quote number: <span id="quot_num">1546751962211</p>
<form method="POST" enctype="multipart/form-data" id="newQuoteForm">
<button type="submit" class="btn btn-primary" name="new-app-btn">Add to Cart</button>
</form>
</body>
<footer>
</footer>
</html>
Here is my on-page form that is OUTSIDE the iFrame.
<form method="POST" enctype="multipart/form-data" id="outer-quote-form" action="/checkout/">
<label class="quote_number">Quote Number:
<input type="text" id="quote_number" name="quote_number" value="">
</label>
<label class="custom_price">price:
<input type="text" id="custom_price" name="custom_price" value="">
</label>
<button type="submit" class="btn btn-primary" name="ws-add-to-cart">Add to Cart</button>
</form>
Then, I have JQuery working to grab the iframed values and puts them in the exterior form. Afterwards, it fires a 'submit()' event on that form.
<script>
jQuery('#newQuoteApp').load(function() {
var iFrameDOM = jQuery("iframe#newQuoteApp").contents();
jQuery('#newQuoteApp').contents().find('#newQuoteForm').submit(function() {
jQuery("input#custom_price").val(jQuery('#newQuoteApp').contents().find('#cust_price').text()); // updated
jQuery("input#quote_number").val(jQuery('#newQuoteApp').contents().find('#quot_num').text());
jQuery("#outer-quote-form").submit();
return true; //return false prevents submit
});
});
</script>
Except when the jquery submit() event fires, the form appears to submit and the page refreshes but no data is posting as it does when I manually submit the form. Is there an extra step here or a better way to fire the form submit with post data?
Edit: Adding the PHP function that isn't firing on jquery submit() for context.
if (isset($_POST['ws-add-to-cart'])) {
add_action( 'init', 'add_product_to_cart' );
function add_product_to_cart() {
global $woocommerce;
global $product;
$product_id = 138;
$woocommerce->cart->add_to_cart($product_id);
}
header("Location:https://www.devsite.com/checkout/");
}
