    copied!<p>I am certain I am making a simple mistake... but simply can't find it. </p> <p>Ultimately I am posting a JSON array from an Android app (that part is working), but for the time being I am simply testing between two PHP pages (1: test PHP page with basic form, and 2: the CodeIgniter final destination) Here is what I have:</p> <p>At the form page:</p> <pre><code>&lt;form action="bambooinvoice/index.php/api2/newinvoice/4/0/0" method="post"&gt; &lt;?php $array = array("items"=&gt;array( "taxable"=&gt;1, "quantity"=&gt;1, "amount"=&gt;123.99, "work_description"=&gt;"this is a test")); $json = json_encode($array); ?&gt; &lt;input type="hidden" name=json value=&lt;?php $json ?&gt; /&gt; &lt;input type="submit" name="btnSendForm" value="Send" /&gt; &lt;/form&gt; </code></pre> <p>This creates (which looks good to me):</p> <pre><code>{"items":{"taxable":1,"Quantity":1,"amount":123.99,"work_description":"this is a test"}} </code></pre> <p>On the codeIgniter side, I have:</p> <pre><code>$input = $this-&gt;input-&gt;post('json'); $items = json_decode($input, TRUE); $amount = 0; foreach ($items as $item) // In case there are multiple 'items' { $taxable = (isset($item['taxable']) &amp;&amp; $item['taxable'] == 1) ? 1 : 0; $invoice_items = array( 'quantity' =&gt; $item['quantity'], 'amount' =&gt; $item['amount'], 'work_description' =&gt; $item['work_description'], 'taxable' =&gt; $taxable ); $this-&gt;_addInvoiceItem($invoice_items); //simply adding contents to DB } </code></pre> <p>In the end I receive the error: (i have received numerous errors actually in all my tweaking, but this is the one I can't seem to shake)</p> <pre><code>Message: Invalid argument supplied for foreach() </code></pre> <p>Edited - to correct a typo.</p>
