Couldn't find anything on this topic, but my goal is to use the HTML5 "placeholder" attribute to show grey text in a form field telling the user what to enter, e.g. "Name."
I'm also using set_value to make sure that if the user submits several form fields and they don't validate, the values they enter remain in the input text boxes.
However, if I use both the placeholder and set_value on a form field, I can't get both to work: When the form first loads, if I use set_value, the placeholder text doesn't appear. So I removed set_value and the placeholder text appears. Then if I submit the form and that text field has an error, since I removed set_value, only the placeholder text appears in the input field.
Is there a CI way around this? Or, if I want to use set_value and placeholder at the same time, should I check if $_POST exists and use either placeholder or set_value?

Post the controller and view code.
[eluser]piddleton[/eluser]
Controller and view code posted:
CONTROLLER:
Code: class Contact extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper('captcha');
$this->load->model('contact_model');
}
public function index()
{
$data = $this->contact_model->get_captcha_word();
$this->load->view('contact',$data);
}
public function send()

// field name, error message, validation rules

$expiration = time()-7200;
$this->db->query("DELETE FROM captcha where captcha_time < ".$expiration);
//-------------------------------------------
//Now see if a captcha exists. Prep binding query

$sql = "SELECT COUNT(*) AS count FROM captcha WHERE word = ? and ip_address = ? AND

$binds = array($_POST['captcha'], $this->input->ip_address(), $expiration);
$query = $this->db->query($sql, $binds);
$row = $query->row();
if ($row->count == 0)
//not a captcha match
{
$this->form_validation->set_message('captcha_check', 'You must submit the correct text that appears in the image.');
return FALSE;
}
else
{
return TRUE;
}
}
}
I only set the placeholder attribute on the email field in the view code
Code: echo validation_errors('<p class="error">');
if (isset($captcha_error))
{
?>
<p class="error">You must submit the word that appears in the image.</p>
<?php
}
?>
<div id="contact_form">
<p>To contact Loam, please fill out the following form. Your email will not be put on any mailing list.
</p>
<fieldset>
<?php
$formarr = array('id' => 'contactform');
echo form_open('contact/send',$formarr);
$namearr = array(
'name' => 'username',
'id' => 'username'
);
echo form_input($namearr, set_value('username', 'Name'));
$emailarr = array(
'name' => 'email_address',
'id' => 'email_address',
'placeholder' => 'Email Address'
);
echo form_input($emailarr);
$data = array(
'name' => 'comment',
'id' => 'comment',
'rows' => '7',
'cols' => '50'
);
echo form_textarea($data, set_value('comment', 'Comment'));
$vals = array(
'word' => $word,
'img_path' => './captcha/',
'img_url' => base_url().'captcha/',
'font_path' => './path/to/fonts/texb.ttf',
'img_width' => '150',
'img_height' => 50,
'expiration' => 7200
);
$cap = create_captcha($vals);
//Insert captcha information in DB to compare with
// after user enters text to match captcha.
$data = array(
'captcha_time' => $cap['time'],
'ip_address' => $this->input->ip_address(),
'word' => $cap['word']
);
$query = $this->db->insert_string('captcha',$data);
$this->db->query($query);
echo $cap['image'] . '<br>';
$caparr = array(
'name' => 'captcha',
'id' => 'captcha'
);
echo form_input($caparr);
echo form_submit('submit', 'Send');
?>
</fieldset>

I'm not able to reproduce the error. Which browser are you using? Try this version:
Code: $emailarr = array(
'name' => 'email_address',
'id' => 'email_address',
'placeholder' => 'Email Address',
'value' => set_value('email_address')
);
echo form_input($emailarr);
Remember to close the form.

Success!
That change worked to use set_value as part of the array instead of a parameter to form_input.
Thanks a bunch. Closed the form as well.
