    <p>I'm making simple file uploading script right now. Everything works well, but when I upload another file with same - script just overwrites it. So, what I want is to be able rename each uploaded file to random name. (Ex. 12jfisfhassa .extension).</p> <p>Here's what I have so far:</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;File Uploader v1.0&lt;/title&gt; &lt;link rel='stylesheet' href='style.css'&gt; &lt;/head&gt; &lt;body&gt; &lt;center&gt; &lt;table width="300" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC"&gt; &lt;tr&gt; &lt;form action="&lt;?php echo $_SERVER['PHP_SELF']; ?&gt;" method="POST" enctype="multipart/form-data"&gt; &lt;td&gt; &lt;table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF"&gt; &lt;tr&gt; &lt;b&gt;Please choose a file:&lt;/b&gt;&lt;br/&gt; &lt;input type="file" name="fileup"/&gt;&lt;br/&gt; &lt;br/&gt; &lt;input type="submit" name='submit' value="Upload"/&gt; &lt;/tr&gt; &lt;/form&gt; &lt;/table&gt; &lt;/body&gt; &lt;/html&gt; &lt;?php $uploadpath = 'upload/'; // directory to store the uploaded files $max_size = 103000000; // maximum file size, in KiloBytes $allowtype = array('bmp', 'gif', 'jpg', 'jpe', 'png', 'rar', 'zip', 'exe'); // allowed extensions if(isset($_FILES['fileup']) &amp;&amp; strlen($_FILES['fileup']['name']) &gt; 1) { $uploadpath = $uploadpath . basename( $_FILES['fileup']['name']); // gets the file name $sepext = explode('.', strtolower($_FILES['fileup']['name'])); $type = end($sepext); // gets extension list($width, $height) = getimagesize($_FILES['fileup']['tmp_name']); // gets image width and height $err = ''; // to store the errors // Checks if the file has allowed type, size, width and height (for images) if(!in_array($type, $allowtype)) $err .= 'The file: &lt;b&gt;'. $_FILES['fileup']['name']. '&lt;/b&gt; not has the allowed extension type.'; if($_FILES['fileup']['size'] &gt; $max_size*1000) $err .= '&lt;br/&gt;Maximum file size must be: '. $max_size. ' KB.'; // If no errors, upload the image, else, output the errors if($err == '') { if(move_uploaded_file($_FILES['fileup']['tmp_name'], $uploadpath)) { echo '&lt;font color="green"&gt;&lt;b&gt;Success!&lt;/b&gt;&lt;/font&gt;'; echo '&lt;br/&gt;File: &lt;b&gt;'. basename( $_FILES['fileup']['name']). '&lt;/b&gt;'; echo '&lt;br/&gt;File type: &lt;b&gt;'. $_FILES['fileup']['type'] .'&lt;/b&gt;'; echo '&lt;br /&gt;Size: &lt;b&gt;'. number_format($_FILES['fileup']['size']/1024, 3, '.', '') .'&lt;/b&gt; KB'; echo '&lt;br/&gt;&lt;br/&gt;File path: &lt;input type="text" value="http://'.$_SERVER['HTTP_HOST'].rtrim(dirname($_SERVER['REQUEST_URI']), '\\/').'/'.$uploadpath.'" readonly&gt;'; } else echo '&lt;b&gt;Unable to upload the file.&lt;/b&gt;'; } else echo $err; } ?&gt; &lt;/center&gt; </code></pre> <p>And yeah, I don't use mysql. Please help? :)</p>

    1. COso change `$uploadpath = $uploadpath . basename( $_FILES['fileup']['name']);` to generate a unique name instead of just blindly using whatever the uploader provided... Your validation code is also rather hideous, and you're simply assuming the upload succeeded.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
