    <p>I have an application I am writing in PHP5, using the CodeIgniter framework. I have it running on both Windows (using Xampp) and Ubuntu (using standard Apache, PHP, MySQL stack).</p> <p>I have a form, that takes XML, parses it (using simpleXML) and posts the results into a database.</p> <p>On Windows - no problem, works as intended.</p> <p>On Linux - big problem. It errors out.</p> <p>I have double checked the XML, and it's fine.</p> <p>I removed a large amount of the XML, and it seems that it is OK.</p> <p>I think it's related to the size of the XML string being posted from the form, but am not sure. Again, on Windows it's OK - on Linux, it errors out.</p> <p>The size of the data posted in the form is ~160k (yeah, that's a lot of text, but it's automated - AND it's gonna eventually be about 200k).</p> <p>The error is below.</p> <p>Any help much appreciated.</p> <blockquote> <p>Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /var/www/ci/system/application/controllers/system.php:49 Stack trace: #0 /var/www/ci/system/application/controllers/system.php(49): SimpleXMLElement->__construct('') #1 [internal function]: System->add_system() #2 /var/www/ci/system/codeigniter/CodeIgniter.php(233): call_user_func_array(Array, Array) #3 /var/www/ci/index.php(115): require_once('/var/www/ci/sys...') #4 {main} thrown in /var/www/ci/system/application/controllers/system.php on line 49</p> </blockquote> <p>Line 49 looks like this:</p> <p><code>$xml = new SimpleXMLElement($this-&gt;input-&gt;post('form_systemXML'));</code></p> <p>EDIT - FIXED</p> <p>Found the issue. Suhosin is installed on Ubuntu. in the file /etc/php5/apache2/conf.d/suhosin.ini, I enabled the line <code>suhosin.post.max_value_length = 65000</code> and changed the value to 195000. Restarted Apache, and all good. Thanks for the pointers guys.</p>

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.
