+<h1>Field Data</h1>
+
+
+<h2>Retrieving Field Names</h2>
+<p>Sometimes it's helpful to gather the field names.</p>
+
+<h2>$this->db->field_names();</h2>
+<p>Returns an array containing the field names. You must supply the table name to the function:</p>
+
+<code>
+$fields = $this->db->field_names('table_name');<br /><br />
+
+foreach ($fields as $field)<br />
+{<br />
+ echo $field;<br />
+}
+</code>
+
+
+
+<h2>Retrieving Field MetaData</h2>
+<p>Sometimes it's helpful to gather the field names or other metadata, like the column type, max length, etc.</p>
+
+<h2>$this->db->field_data();</h2>
+<p>Returns an array of objects containing field information.</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 />
+ echo $field->name;<br />
+ echo $field->type;<br />
+ echo $field->max_length;<br />
+ echo $field->primary_key;<br />
+}
+</code>
+
+<p>If you have run a query already you can use the result oject instead of supplying the table name:</p>
+
+<code>
+$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>
+</ul>
