typeahead bootstrap不使用来自php页面的动态数据

Question

I want to use typeahead on input text, but it's not working.

my html :

<link rel="stylesheet" type="text/css" href="<?php echo base_url('asset/css/typeahead.css')?>">

<?php foreach ($driver as $d) { ?>
    <input type="text" class="form-control input-lg typeahead" autocomplete="off" data-provide="typeahead" data-source="<?php echo $d['email']; }; ?>" id="email"  name="email">

<script src="<?php echo base_url('asset/js/typeahead.bundle.min.js') ?>"></script>

My controller :

$this->db->select("*");
$this->db->from('user');
$query = $this->db->get();
$data['driver'] = $query->result_array();

When I start typing in input text, it shows nothing, it should be dropdown the email list provided from select query. No error return.

There is problem in your code. You are looping for each $driver and showing its email id in the data-source and the input tag is not closing.

For using bootstrap typeaded

1. Get list of all emails from $driver using following code
   $emails = array_column($driver, 'email');
2. Create a string which will contain all the emails. All the emails should be wrapped in double quotes( " ) and seperated by comma ( , )
   $csv = "\\"" . implode("\\",\\"", $emails) . "\\"";
3. Now create the typeahed input tag
   <input type="text" class="form-control input-lg typeahead" autocomplete="off" data-provide="typeahead" data-source='[<?php echo $csv; ?>]' id="email" name="email">
   Remember that the data-source attribute has single quote as start and end.
