    <p>First post on stack overflow... so go easy on me! </p> <p>There doesn't seem to be a suitable solution to the Drupal FAPI multiple callback issue for simple form submissions. </p> <p>THE PROBLEM: My form, when submitted, adds two entries to the respective database table. Given that there is only one call to add it to the database, I feel it's safe to assume that the query is run twice (hence the dual entries).</p> <p>The following code may help to provide a basis for a solution. Oh, it's Drupal 7 too, so documentation is still very much D6 centric.</p> <pre><code>function mymodule_sidebar_form_add_submit(&amp;$form, &amp;$form_state) { $form_values = $form_state['values']; $se_title = check_plain(trim($form_values['title'])); $se_link = url(trim($form_values['link'])); $se_content = check_plain(trim($form_values['content'])); $se_image = isset($form_values['image']) ? $form_values['image'] : ''; // The multi-line part below is actually a single line the real code $query = sprintf("INSERT INTO sidebar_element(title, image_url, content) VALUES ('%s', '%s', '%s');", $se_title, $se_image, $se_content); db_query($query); drupal_set_message(t('Sidebar Element has been added successfully.')); } </code></pre> <p>... and my form function contains a submit button:</p> <pre><code> $form['submit'] = array( '#value' =&gt; t('Add Sidebar'), '#type' =&gt; 'submit', '#title' =&gt; t('Add Sidebar'), '#submit' =&gt; array('mymodule_sidebar_form_add_submit'), ); </code></pre> <p>I guess the questions I need answered are:</p> <ol> <li>Why is there a double callback in the first place?</li> <li>Is there a way to identify the first callback?</li> </ol> <p>Thanks in advance to all.</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.
