    <p>Hello guys I have a little problem. My problem is I want to use jquery form validation plugin together with codeigniter. As of now I can validate my form using jquery validation rules. Like checking the required fields, checking length of input, checking valid email, etc... But for checking the availability of the data in my database I always got an error. I used the remote function but I can't validate my form. Here's my code I hope you can help me.</p> <p><strong>addNewItem.php</strong></p> <pre><code> &lt;script type="text/javascript"&gt; (function($,W,D){ var JQUERY4U = {}; JQUERY4U.UTIL = { setupFormValidation: function() { $("#login-form").validate({ rules: { name: { required: true, remote: { type: 'post', url: &lt;?php echo site_url('category_model/checkName'); ?&gt;, data: { 'name': $('#name').val() }, datatype: 'json' } }, description: { required: true } }, messages: { username: { remote: "Category name already taken!" } description: "Please provide a description for category!" } }); } } //when the dom has loaded setup form validation rules $(D).ready(function($) { JQUERY4U.UTIL.setupFormValidation(); }); })(jQuery, window, document); &lt;/script&gt; &lt;div&gt; &lt;?php $attr = array('class'=&gt;'form-signin','id'=&gt;'login-form','novalidate'=&gt;'novalidate'); ?&gt; &lt;?php echo form_open('category_controller/insertItem',$attr); ?&gt; &lt;h2 class="form-signin-heading"&gt;&lt;/h2&gt; &lt;h5 style="font-weight: normal;"&gt;Category Name:&lt;/h5&gt; &lt;input type="text" class="input-block-level" placeholder="Category Name" name="name" autofocus="autofocus" value="" required="requried" id="name" /&gt; &lt;h5 style="font-weight: normal;"&gt;Desciption&lt;/h5&gt; &lt;input type="text" class="input-block-level" placeholder="Description" name="description" value="" required="required" id="description" /&gt; &lt;br /&gt; &lt;div align="right"&gt; &lt;input type="submit" value="OK" class="btn btn-large btn-primary" /&gt; &lt;input type="button" value="CANCEL" class="btn btn-large btn-primary" name='cancel' /&gt; &lt;/div&gt; &lt;?php echo form_close(); ?&gt; </code></pre> <p> </p> <p><strong>my model (category_model/checkName)</strong></p> <pre><code>public function checkName(){ $catname = ucwords($this-&gt;input-&gt;post('name')); $validate = "SELECT COUNT(*) AS valid FROM sales_category WHERE salescatname = '{$catname}'"; $testvalidate = $this-&gt;db-&gt;query($validate); foreach($testvalidate-&gt;result_array() as $row){ $is_valid = $row['valid']; } if($is_valid &gt; 0){ return TRUE; }else{ return FALSE; } } </code></pre>

    3. COIs the ajax call working? you can use the Network tab on Chrome Dev Tools to analyze XHR requests. Also you cannot call a method from a model directly from a url, so in your url `category_model` should be the name of your controller unless of course you are using url routing.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
