    text
    copied!<p>I'm working my way around Drupal API with limited success.</p> <p>I want to have a URL with a form in it, so that when I "GET" that URL I get the form (have that), when I input a wrong "code" into that form and POST that same URL I get the same form with an error message (have that too), but when I POST that <strong>same URL</strong> with the right "code" I get a different code, no longer displaying the previous form.</p> <p>No redirects, all the requests (posts and gets) should be targeted to domain.com/entry</p> <p>This is a code I have (simplified):</p> <pre class="lang-php prettyprint-override"><code>function entry_menu() { $items['entry'] = array( 'page callback' =&gt; 'entry_handler', 'access arguments' =&gt; array('access entry'), type =&gt; MENU_CALLBACK, ); return $items; } function entry_handler() { return drupal_get_form('entry_daily_code'); } function entry_daily_code($form, &amp;$form_state) { $form['code'] = array( '#type' =&gt; 'textfield', '#title' =&gt; 'Code for Today', ); form['submit'] = array( '#type' =&gt; 'submit', '#value' =&gt; 'Access', ); return $form; } function entry_daily_code_submit($form, &amp;$form_state) { if (isset($form_state['values']['code']) &amp;&amp; $form_state['values'] == "1234") { drupal_set_message(t('Success')); } else { drupal_set_message(t('Fail')); } } </code></pre> <p>I imagine that what I want to do should happen in "entry_handler".</p> <p>It needs to know the status returned by the form, and to either return the form, or a different content, but I'm failing at that.</p> <p>Made a diagram to illustrate my point, in case it wasn't coming across: <img src="https://www.evernote.com/shard/s4/sh/5cf53bc9-6d2a-4338-846f-3c2cff35e6c5/f3d81fb81ff31b6f8a3735c683e7c2a4/deep/0/Blank.png" alt="diagram"></p> <p>Thanks for any pointers in the right direction.</p>
