| <p>The <code class="docutils literal"><span class="pre">$config</span></code> array contains your configuration variables. It is passed to |
| the <code class="docutils literal"><span class="pre">$this->pagination->initialize()</span></code> method as shown above. Although |
| there are some twenty items you can configure, at minimum you need the |
| three shown. Here is a description of what those items represent:</p> |
| <ul class="simple"> |
| <li><strong>base_url</strong> This is the full URL to the controller class/function |
| containing your pagination. In the example above, it is pointing to a |
| controller called “Test” and a function called “page”. Keep in mind |
| that you can <a class="reference internal" href="../general/routing.html"><span class="doc">re-route your URI</span></a> if you |
| need a different structure.</li> |
| <li><strong>total_rows</strong> This number represents the total rows in the result |
| set you are creating pagination for. Typically this number will be |
| the total rows that your database query returned.</li> |
| <li><strong>per_page</strong> The number of items you intend to show per page. In the |
| above example, you would be showing 20 items per page.</li> |
| </ul> |
| <p>The <code class="docutils literal"><span class="pre">create_links()</span></code> method returns an empty string when there is no |
| pagination to show.</p> |
| </div> |

| <h3><a class="toc-backref" href="#id3">Setting preferences in a config file</a><a class="headerlink" href="#setting-preferences-in-a-config-file" title="Permalink to this headline">¶</a></h3> |
| <p>If you prefer not to set preferences using the above method, you can |
| instead put them into a config file. Simply create a new file called |
| pagination.php, add the <code class="docutils literal"><span class="pre">$config</span></code> array in that file. Then save the file |
| in <em>application/config/pagination.php</em> and it will be used automatically. |
| You will NOT need to use <code class="docutils literal"><span class="pre">$this->pagination->initialize()</span></code> if you save |
| your preferences in a config file.</p> |

| <div class="section" id="customizing-the-pagination"> |
| <h2><a class="toc-backref" href="#id4">Customizing the Pagination</a><a class="headerlink" href="#customizing-the-pagination" title="Permalink to this headline">¶</a></h2> |
| <p>The following is a list of all the preferences you can pass to the |
| initialization function to tailor the display.</p> |
| <p><strong>$config[‘uri_segment’] = 3;</strong></p> |
| <p>The pagination function automatically determines which segment of your |
| URI contains the page number. If you need something different you can |
| specify it.</p> |
| <p><strong>$config[‘num_links’] = 2;</strong></p> |
| <p>The number of “digit” links you would like before and after the selected |
| page number. For example, the number 2 will place two digits on either |
| side, as in the example links at the very top of this page.</p> |
| <p><strong>$config[‘use_page_numbers’] = TRUE;</strong></p> |
| <p>By default, the URI segment will use the starting index for the items |
| you are paginating. If you prefer to show the the actual page number, |
| set this to TRUE.</p> |
| <p><strong>$config[‘page_query_string’] = TRUE;</strong></p> |
| <p>By default, the pagination library assume you are using <a class="reference internal" href="../general/urls.html"><span class="doc">URI |
| Segments</span></a>, and constructs your links something |
| like:</p> |
| <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">http</span><span class="o">://</span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">test</span><span class="o">/</span><span class="nx">page</span><span class="o">/</span><span class="mi">20</span> |
| </pre></div> |
| </div> |
| <p>If you have <code class="docutils literal"><span class="pre">$config['enable_query_strings']</span></code> set to TRUE your links |
| will automatically be re-written using Query Strings. This option can |
| also be explicitly set. Using <code class="docutils literal"><span class="pre">$config['page_query_string']</span></code> set to TRUE, |
| the pagination link will become:</p> |
| <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">http</span><span class="o">://</span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">?</span><span class="nx">c</span><span class="o">=</span><span class="nx">test</span><span class="o">&</span><span class="nx">m</span><span class="o">=</span><span class="nx">page</span><span class="o">&</span><span class="nx">per_page</span><span class="o">=</span><span class="mi">20</span> |
| </pre></div> |
| </div> |
| <p>Note that “per_page” is the default query string passed, however can be |
| configured using <code class="docutils literal"><span class="pre">$config['query_string_segment']</span> <span class="pre">=</span> <span class="pre">'your_string'</span></code></p> |
| <p><strong>$config[‘reuse_query_string’] = FALSE;</strong></p> |
| <p>By default your Query String arguments (nothing to do with other |
| query string options) will be ignored. Setting this config to |
| TRUE will add existing query string arguments back into the |
| URL after the URI segment and before the suffix.:</p> |
| <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">http</span><span class="o">://</span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">test</span><span class="o">/</span><span class="nx">page</span><span class="o">/</span><span class="mi">20</span><span class="o">?</span><span class="nx">query</span><span class="o">=</span><span class="nx">search</span><span class="o">%</span><span class="nx">term</span> |
| </pre></div> |
| </div> |
| <p>This helps you mix together normal <a class="reference internal" href="../general/urls.html"><span class="doc">URI Segments</span></a> |
| as well as query string arguments, which until 3.0 was not possible.</p> |
| <p><strong>$config[‘prefix’] = ‘’;</strong></p> |
| <p>A custom prefix added to the path. The prefix value will be right before |
| the offset segment.</p> |
| <p><strong>$config[‘suffix’] = ‘’;</strong></p> |
| <p>A custom suffix added to the path. The suffix value will be right after |
| the offset segment.</p> |
| <p><strong>$config[‘use_global_url_suffix’] = FALSE;</strong></p> |
| <p>When set to TRUE, it will <strong>override</strong> the <code class="docutils literal"><span class="pre">$config['suffix']</span></code> value and |
| instead set it to the one that you have in <code class="docutils literal"><span class="pre">$config['url_suffix']</span></code> in |
| your <strong>application/config/config.php</strong> file.</p> |
