Body
<p>Two things:</p> <ol> <li>Using Javascript</li> <li>Using APC</li> </ol> <p><strong>Javascript:</strong></p> <pre><code>You can use plupload (http://www.plupload.com/) - pretty good multiple file uploader Pretty decent JS plugin for uploading files in PHP in two methods, 1. normal upload 2. chunk based uploading. </code></pre> <p>Limitations/Assumptions:</p> <pre><code>1. Flash Plugin - in the browser 2. Session problem - since it's flash, a different session's are created for each file upload. </code></pre> <p><strong>APC/PHP</strong></p> <p>Using APC - you can create a progress-bar on our own.</p> <p>Limitation/Assumptions:</p> <pre><code>1. Install APC on the server - using PECL (pecl install APC) 2. Write a separate code to get the status of upload. </code></pre> <p>Code:</p> <p><em>getprogress.php</em></p> <pre><code><?php if(isset($_GET['progress_key'])) { $status = apc_fetch('upload_'.$_GET['progress_key']); echo $status['current']/$status['total']*100; } ?> </code></pre> <p><em>upload.php</em></p> <pre><code><?php $id = uniqid(""); ?> <html> <head><title>Upload Example</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> </head> <body> <script type="text/javascript"> function getProgress(){ $.get("getprogress.php?progress_key=<?php echo($id)?>", function(percent) { document.getElementById("progressinner").style.width = percent+"%"; if (percent < 100){ setTimeout("getProgress()", 100); } }); } function startProgress(){ document.getElementById("progressouter").style.display="block"; setTimeout("getProgress()", 1000); } </script> <iframe id="theframe" name="theframe" src="fileupload.php?id=<?php echo($id) ?>" style="border: none; height: 100px; width: 400px;" > </iframe> <br/><br/> <div id="progressouter" style="width: 500px; height: 20px; border: 6px solid red; display:none;"> <div id="progressinner" style="position: relative; height: 20px; background-color: purple; width: 0%; "> </div> </div> </body> </html> </code></pre> <p><em>fileupload.php</em> </p> <pre><code><?php $id = $_GET['id']; ?> <form enctype="multipart/form-data" id="upload_form" action="target.php" method="POST"> <input type="hidden" name="APC_UPLOAD_PROGRESS" id="progress_key" value="<?php echo $id?>"/> <input type="file" id="test_file" name="test_file"/><br/> <input onclick="window.parent.startProgress(); return true;" type="submit" value="Upload!"/> </form> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
