In my CodeIgniter project I have a Login controller that load this view:

<ul class="sub-menu">
        <a href="javascript:;" class = "menu-item" data-target="../indoamericana/soporte/callSupport/"> Mis solicitudes </a>

The controller: soporte, function: callSupport

public function callSupport($index = null, $order = null){
    $session_data = $this->session->userdata('session_user');
    $data['solicitud']  = $this->helpdesk_model->getRequest($session_data['usuario'], $index, $order); 
    $data['categories'] = $this->helpdesk_model->getCategories();
    $this->load->view('modules/help_desk/supports', $data);

With jQuery I call the controller and render in a page content that is a <div> element:

$(".sub-menu .menu-item, .module-item").click(function(event) {
    $("title").text( $( this ).text() );

In the view 'modules/help_desk/supports':

<table class="table table-striped table-hover" id="admin-support" data-target="soporte/callSupport/"> 
    <th>Estado <a href="javascript:;"><i class="icon-sort" data-sort="status"></i></a></th>
    <th>Prioridad <a href="javascript:;"><i class="icon-sort" data-sort="priority"></i></a></th>
    <th>Responsable <a href="javascript:;"><i class="icon-sort" data-sort="id_responsible"></i></a></th>
    <?php foreach ($solicitud as $key => $value) { ?>
        <td><span class="label label-sm <?= $value['label']?> "><?= ucfirst($value['status']) ?></span></td>
        <td><span class="badge <?= $value['class']?> "><?= $value['priority'] ?></span></td>
        <td><?= $value['name'].' '.$value['last_name'] ?></td>
    <?php  } ?>

As you can see, in the first <td> a put an anchor tag calls another controller with jQuery similar than before. Please be critical, very severe with me.

General comments

I don't see much wrong with the code. The biggest concern I might have is that PHP code is mixed in with the HTML - an alternative to this would be using a template system. CodeIgniter has the template parser class which should allow you to do this.

Please be critical, very severe with me.

Okay - I am not typically this critical but you asked for it! The next section has a couple other review points

Minor nitpicks

In the PHP code, $data is not declared before values are assigned to specific keys:

$data['solicitud']  = $this->helpdesk_model->getRequest($session_data['usuario'], $index, $order); 

I don't see a problem with this practice but the PHP documentation advises against it:

If $arr doesn't exist yet, it will be created, so this is also an alternative way to create an array. This practice is however discouraged because if $arr already contains some value (e.g. string from request variable) then this value will stay in the place and [] may actually stand for string access operator. It is always better to initialize a variable by a direct assignment.

I tried running the jQuery callback through the demo page on eslint.org. It showed this warning:

'event' is defined but never used.

For this line:

$(".sub-menu .menu-item, .module-item").click(function(event) {

While event could be used if necessary, it isn't needed.
