POProblems with PhP Yes/No and Switch/Case routine
text
Body
copied!<p>I have taken over a PhP application that populates events in a MySQL database.</p> <p>I have modified it so it allows events to have multiple recipients. No issues.</p> <p>My issue is that when a multi user event is clicked on to update or more importantly to delete I ask using a Javascript function 'Apply to all users on this event?'. Question works fine. I appreciate PhP is server side and JS runs on the client side. </p> <p>So what I tried is a hidden field in my edit form which defaults to 'adddetails' and if they press yes to the multi user question populate it with addmultidetails (which I verified by making a text field temporarily). You can see from the original <code><form></code> tage that adddetails is hard coded into the post url as a GET paramter.</p> <pre><code><form action="data.php?method=adddetails<?php echo isset($event)?"&id=".$event->Id:""; ?>" class="fform" id="fmit" name="fm" method="post"> </code></pre> <p>// data.php //</p> <pre><code><?php session_start(); function add($st, $et, $sub, $ade){ return $ret; } function addDetailed($st, $et, $sub, $ade, $dscr, $loc, $color, $tz){ return $ret; } function listByRange($sd, $ed){ return $ret; } function list($day, $type){ } function update($id, $st, $et){ return $ret; } function updateDetailed($id, $st, $et, $sub, $ade, $dscr, $loc, $color, $tz){ return $ret; } function updateMultiDetailed($id, $st, $et, $sub, $ade, $dscr, $loc, $color, $tz){ return $ret; } function remove($id){ return $ret; } $method = $_GET["method"]; switch ($method) { case "add": break; case "list": break; case "update": break; case "remove": break; case "adddetails": break; case "addmultidetails": break; } echo json_encode($ret); ?> </code></pre> <p>All the post data as originally posted is correct, however if I try to access the hidden field, updmethod, and changed the data.php to have <code>$method = $_POST["updmethod"];</code> my program just freezes without any error messages (I have <code>error_reporting(E_ALL);</code> in my modules).</p> <p>Then I tried another form to store the hidden updmethod so I could just change the <code>method=</code> in </p> <pre><code><form action="data.php?method=adddetails<?php echo isset($event)?"&id=".$event->Id:""; ?>" class="fform" id="fm" name="fm" method="post"> </code></pre> <p>to be built dynamically but am having no success there either.</p> <p>I would appreciate any help with this. I am not being lazy. I have spent 2 days working on a problem I thought I could resolve quickly and have read 'tutorials' on Server side/Client side relationship. Tried to understand Ajax etc but no matter what I seem to achieve I then encounter another wall.</p> <p>I know my problem all stems from the Php/Javascript realtionship and trying to get the response from the Javascript function to my Php....but I am stumped.</p> <p>I will not be offended if I am told my approach is all wrong, but rememeber I am working with an existing code.</p>
