    <p>i have a table which shows some mysql data, every entry has a checkbox to select individual entries, now i want to be able to export those selected entries into a xml or txt file, i tried this:</p> <pre><code>&lt;?php if ($_POST['exporttxt']) { for ($i = 0; $i &lt; count($_POST['checkbox']); $i++) { $export_id = $checkbox[$i]; $sql = "SELECT * FROM table WHERE id='$export_id'"; $result = mysql_query($sql); } $output = "&lt;?xml version=\"1.0\" encoding=\"UTF-8\"?&gt;\n&lt;root&gt;\n"; if ($result-&gt;num_rows &gt; 0) { while ($myrow = $result-&gt;fetch_assoc()) { $output .= "\t&lt;row&gt;\n"; foreach ($myrow as $_name =&gt; $_value) { $output .= "\t\t&lt;$_name&gt;$_value&lt;/$_name&gt;\n"; } $output .= "\t&lt;/row&gt;\n"; } } $output .= "&lt;/root&gt;"; } header('content-type: text/xml'); header('content-disposition: attachment; filename=data_export.xml'); echo $output; exit; ?&gt; </code></pre> <p>But that didn't work at all, any hints ?</p> <p>I've changed the code a bit, i am now using this</p> <pre><code>&lt;?php if ($_POST['exporttxt']) { for($i=0;$i&lt;count($_POST['checkbox']);$i++){ $export_id = $checkbox[$i]; $text = mysql_query("SELECT code FROM ticket WHERE id='$export_id'"); $text = mysql_fetch_assoc($text); $text = $text["code"]; ob_end_flush(); header("Content-type: text/plain"); header("Content-disposition: attachment;filename=\"filename.txt\""); header("Content-Type: application/force-download"); header("Content-Type: application/octet-stream"); header("Content-Type: application/download"); header("Content-Description: File Transfer"); header("Content-Length: ".strlen($output).";\n"); echo($text); } } ?&gt; </code></pre> <p>I now get proper output on my screen, but it won't offer me to download the file ?</p>

    2. COcan you echo the $export_id to make sure your getting into the loop. Also it's not a good idea to a count in the for arguments. Set $count = count($_POST['checkbox']) before the for loop you'll get better performance.

    3. COechoing $export_id works - partly, it is showing the id's from the checkboxes that have been selected, although only 1, why is that ? but apart from that, if i select ID 305 for example and click submit it shows "305", so that should be fine ?

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.
