    copied!<p>Is there a way I can pass the php option value variable $option_value['price'] into javascript as a string, then each time a different option is chosen, the javascript 'updates' the string with the new value. I have tried with onchange() but must be doing something wrong. I am sure my mistake is because php is server side and javascript is client side, but I have no idea how to get the two to act how I want.</p> <pre><code>&lt;?php if ($options) { ?&gt; &lt;?php foreach ($options as $option) { ?&gt; &lt;?php if ($option['type'] == 'select') { ?&gt; &lt;span id="option-&lt;?php echo $option['product_option_id']; ?&gt;" class="option"&gt; &lt;select name="option[&lt;?php echo $option['product_option_id']; ?&gt;]" onchange="getIt(this)"&gt; &lt;?php foreach ($option['option_value'] as $option_value) { ?&gt; &lt;option value="&lt;?php echo $option_value['product_option_value_id']; ?&gt;"&gt;&lt;?php echo $option_value['name']; ?&gt; &lt;?php if ($option_value['price']) { ?&gt; &lt;?php $option_value['price']; ?&gt; &lt;?php } ?&gt; &lt;/option&gt; &lt;?php } ?&gt; &lt;/select&gt; &lt;/span&gt; </code></pre> <p>I have tried:</p> <pre><code>&lt;script type="text/javascript"&gt; function getIt(elm) { var val = elm.options[elm.selectedIndex].text; window.alert(val); } &lt;/script&gt; </code></pre> <p>and</p> <pre><code>&lt;script type="text/javascript"&gt; function getIt() { var val = "&lt;?php $option_value['price']; ?&gt;"; window.alert(val); } &lt;/script&gt; </code></pre>
