copied!<p><strong>Answer</strong></p> <p>Thanks to Kenneth's answer and suggestions, I did figure out what I needed to do. There's an added layer because this is an ExpressionEngine site, but basically I needed to tell the function that the variable was coming in from the post, like this:</p> <pre><code>$newItems = $this->EE->input->post('newItems'); $newItems = json_decode($newItems, true); </code></pre> <p><strong>UPDATED</strong></p> <p>After following Kenneth's suggestion below, I was able to get the javascript to recognize that I was passing in <code>r.newItems</code>. But my php function doesn't recognize that it's receiving an array. This is the error I'm getting:</p> <pre><code>PHP Warning: Missing argument 1 for Order::addReorderToCart() </code></pre> <p>My php function looks like this:</p> <pre><code>public function addReorderToCart($newItems) { error_log("newitems"); error_log(print_r($newItems,1)); // this is not printing anything $_SESSION['order']['items'] = array_merge($_SESSION['order']['items'], $newItems); $this->EE->app->addToCart(); $rtnArray['success'] = true; } </code></pre> <p>What do I need to do to translate the array that's being sent through the jquery so that the php function recognizes it as an array?</p> <p>I have the following javascript/jquery code that runs as a result of another ajax call:</p> <pre><code>function ohReorderAjaxReturn(data) { console.log("ajax return"); console.dir(data); var r = eval(data); console.log("r"); console.dir(r); if(data.unavailableItems instanceof Array && data.unavailableItems.length > 0) { // there are unavailable items; ask if they want to go ahead Modal({ title: r.errTitle, text: r.errMsg, // need to update this to contain correct text including store address and unavailableItems yellow_button: { btn_text: "It's OK, continue", action: function(r){ console.log("r inside function"); console.log(r); // need ajax call to addReorderToCart $.post('/site/ajax/order/addReorderToCart', {'newItems': r.newItems}, function(data) { var ret = eval(data); if( ret.success == 1 ) { document.location = '/site/order_summary'; } else { alert("error"); } }); } }, black_button: { btn_text: "Cancel" } }); } else { console.log("not an array"); // there are no unavailable items; add to cart and continue on } } </code></pre> <p>A <code>console.log</code> right inside the <code>if(data.unavailableItems instanceof Array && data.unavailableItems.length > 0)</code> line lets me know that it gets that far. It is popping up the modal, but the <code>action</code> part (which calls another php function via ajax) doesn't seem to be getting the <code>newItems</code> value passed in. Here's a screenshot of Firebug; you can see that the <code>console.dir(r)</code> a few lines inside the function signature returns information for <code>newItems</code>. Why does <code>r</code> become undefined when I try to pass it into the post? And how can I do it, if what I'm doing now is wrong?</p> <p><img src="https://i.stack.imgur.com/KuhEs.png" alt="enter image description here"></p>
