-<h1>Field Data</h1>
-
-
-<h2>$this->db->list_fields()</h2>
-<p>Returns an array containing the field names. This query can be called two ways:</p>
-
-
-<p>1. You can supply the table name and call it from the <dfn>$this->db-></dfn> object:</p>
-
-<code>
-$fields = $this->db->list_fields('table_name');<br /><br />
-
-foreach ($fields as $field)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $field;<br />
-}
-</code>
-
-<p>2. You can gather the field names associated with any query you run by calling the function
-from your query result object:</p>
-
-<code>
-$query = $this->db->query('SELECT * FROM some_table');
-<br /><br />
-
-foreach ($query->list_fields() as $field)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $field;<br />
-}
-</code>
-
-
-<h2>$this->db->field_exists()</h2>
-
-<p>Sometimes it's helpful to know whether a particular field exists before performing an action.
-Returns a boolean TRUE/FALSE. Usage example:</p>
-
-<code>
-if ($this->db->field_exists('field_name', 'table_name'))<br />
-{<br />
-&nbsp;&nbsp; // some code...<br />
-}
-</code>
-
-<p>Note: Replace <em>field_name</em> with the name of the column you are looking for, and replace
-<em>table_name</em> with the name of the table you are looking for.</p>
-
-
-<h2>$this->db->field_data()</h2>
-<p>Returns an array of objects containing field information.</p>
-<p>Sometimes it's helpful to gather the field names or other metadata, like the column type, max length, etc.</p>
-
-
-<p class="important">Note: Not all databases provide meta-data.</p>
-
-<p>Usage example:</p>
-
-<code>
-$fields = $this->db->field_data('table_name');<br /><br />
-
-foreach ($fields as $field)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $field->name;<br />
-&nbsp;&nbsp;&nbsp;echo $field->type;<br />
-&nbsp;&nbsp;&nbsp;echo $field->max_length;<br />
-&nbsp;&nbsp;&nbsp;echo $field->primary_key;<br />
-}
-</code>
-
-<p>If you have run a query already you can use the result object instead of supplying the table name:</p>
-
-<code>
-$query = $this->db->query("YOUR QUERY");<br />
-$fields = $query->field_data();
-</code>
-
-
-<p>The following data is available from this function if supported by your database:</p>
-
-<ul>
-<li>name - column name</li>
-<li>max_length - maximum length of the column</li>
-<li>primary_key - 1 if the column is a primary key</li>
-<li>type - the type of the column</li>
