I added a new page to the OSTicket version 10 Beta and I am trying to auto-populate data based on a select option value. I have a customer that could have multiple locations and each location has a different address, contact, email, etc...When you select a different location in the dropdown it does a page submit and I get this error:Valid CSRF Token RequiredIf I take copy that querystring, hit back in the browser and refresh the page so that it's working properly and paste that querystring into the url it works. It doesn't change the location in the select option but all the other data works so the problem is that onchange event with the select. Here is the code:<form id="customer_form" action="customers.php?t=customer<?='&id='.$cust->getId()?>" method="post"> <table style="width%;border;border-collapse;border-spacing;padding"> <tr> <td width=50%> <table class="ticketinfo" style="width%;border;border-collapse;border-spacing;padding;margin auto;text-align;"> <tr height=30 valign=bottom> <th>Site Name</th> <td> <select name="location" onchange='document.getElementById("customer_form").action+="&sub_id="+this.value;document.getElementById("customer_form").submit();'> <?php if (($locs=Cust:($cust->getId()))) { foreach ($locs as $loc) { $sel=($_REQUEST && $_REQUEST==$id)?'selected="selected"':''; echo sprintf('<option value="%d" %s>%s</option>',$loc,$sel,$loc); } } ?> </select>Why might this be happening?
