if($this->input->post('save')){
$this->add_model->insert_into_db();
$this->load->view('pages/home');//loading success view
}
}
}
I think you should try this in your controler:
function insert_to_db()
{
$this->load->model('add_model');
if( isset( $this->input->post('save') ) )
{
$this->add_model->insert_into_db();
//loading success view
$this->load->view('pages/home');
}
}

First of all, put your code in a snippet so it will be easier for us to understand. Anyway, I'll tell how to attach blur event using jQuery.
$("input#name").on("blur", function()
{
if(!this.value)
{
alert("Please fill out the name");
}
});

If you need any other help, just let me know :-)
I am trying to get to know CodeIgniter. I just couldn’t figure out what the problem with the code below is. However, when I click on the ‘submit’ button, nothing happens. I mean no record is inserted in the database table.
The php in the view is as follows.
<?php echo form_open('site/create'); ?>
<?php echo form_close();?>
<p>
<label for="title">Title</label>
<input type="text" name="title" id="title" />
</p>
<p>
<label for="content">Content</label>
<input type="text" name="content" id="content" />
</p>
<p>
<input type="submit" value="submit" />
</p>
Down goes the controller
<?php
class site extends CI_Controller
{
function index()
{
$this->load->view('options_view');
}
function create()
{
$rec=array(
'title' => $this->input->post('title'),
'content'=>$this->input->post('content')
);
$this->site_model->add_record($rec);
$this->index();
}
}
?>
And the model is as follows.
<?php
class site_model extends CI_Model
{
function get_records()
{
$query=$this->db->get('other');
return $query->result();
}
function add_record($rec)
{
$this->db->insert('other',$rec);
return;
}
function update_record($rec)
{
$this->db->where('id',2);
$this->db->update('other',$rec);
}
function delete_rec()
{
$this->db-delete();
}
}
?>
The form close has to be at the end:
<?php echo form_open('site/create'); ?>
<p>
<label for="title">Title</label>
<input type="text" name="title" id="title" />
</p>
<p>
<label for="content">Content</label>
<input type="text" name="content" id="content" />
</p>
<p>
<input type="submit" value="submit" />
</p>
<?php echo form_close();?>
It's better and easier to use the form library from codeigniter.
I believe you must be familiar with Html already to start using codeIgniter so this should be easy... Like all html forms you need to have an opening tag and a closing tag, what you have done is open and close the form at the top before the other elements. So as expected, the submit button wont do what you need it to do. The solution is to move
<?php echo form_close();?>
to the bottom so your code appears as such
<?php echo form_open('site/create'); ?>
<p>
<label for="title">Title</label>
<input type="text" name="title" id="title" />
</p>
<p>
<label for="content">Content</label>
<input type="text" name="content" id="content" />
</p>
<p>
<input type="submit" value="submit" />
</p>
<?php echo form_close();?>
All the best.
I want to fill this form, but i dont know how to do it since it only have a classname.
All the examples i saw have an id or a name, to fill the form and submit it, please help.
<form class="header_form" method="post" action="">
<div class="lgn-items">
<div class="login_item">
<label>Email</label>
<input type="text" name="email" tabindex="1" class="inputtext" id="email" />
</div>
<div class="login_item" >
<label>Password</label>
<input type="password" name="password" tabindex="2" class="inputtext" id="pass" />
</div>
<div class="lgn-add">
Registration <span>|</span>
Forgot your password ?
<div class="rembo">
<input type="checkbox" name="remember" value="1" /> Remember me
</div>
</div>
</div>
<div class="login_item lgn-btn" >
<input type="submit" name="login_button" value="Login" tabindex="3" class="login" />
</div>
</form>
You can access to your form using any selector. In your case you to it like this.
casper.then(function () {
casper.fill('form.header_form', {
/** Your parameters here **/
}, true);
});
I am trying to validate email and password using the CodeIgniter's form_validation library. But when I typed wrong email or password the error message of validation_rules is not displayed.
The controller:
public function anuncios()
{
$usr=$this->input->post('Usuario');
$this->input->post('Contrasenya');
$this->form_validation->set_rules('drcorreo','Nombre de usuario',
'trim|required|min_length[5]|xss_clean');
$this->form_validation->set_rules('contrasena','Contraseña',
'trim|required|min_length[8]|md5|xss_clean');
if($this->form_validation->run())
{
$this->load->model('modelo_usuarios');
if($this->modelo_usuarios->puede_entrar())
{
echo "Credenciales correctos";
$this->load->model("modelo_bd");
$data['vanc']=$this->modelo_bd->datos();
$this->load->view('vancios',$data);
return true;
}
else { //this one is never displayed
echo "Credenciales incorrectos";
echo "Usuario o contrasenya incorrectos<br /><br />";
$this->load->view('indice');
return false;
}
}
else { //this one is displayed but not the rules specified in
//form_validation_lang.php file
echo "Las reglas no son validas";
$this->load->view('indice');
}
}
View:
<div id="acformulario">
<form action="http://localhost/Pruebas/index.php/cindice/anuncios" method="post">
<label for="correo" id="dcorreo">Dirección de correo</label>
<input type="text" name="drcorreo" id="dcc"/><br /><br />
<label for="contrasenya" id="cont">Contraseña</label>
<input type="password" name="contrasena" id="cmcont"/><br /><br />
<!--<label for="enviar"></label>-->
<input type="submit" name="envia" id="bentrar" value="Entrar" />
</form>
</div>
Why error messages are not displayed?
Thanks.
i assume you call "form" helper in your autoload.php file,
use your view like this;
<div class="errors"><?php echo validation_errors(); ?></div>
<div id="acformulario">
<form action="http://localhost/Pruebas/index.php/cindice/anuncios" method="post">
<label for="correo" id="dcorreo">Dirección de correo</label>
<input type="text" name="drcorreo" id="dcc"/><br /><br />
<label for="contrasenya" id="cont">Contraseña</label>
<input type="password" name="contrasena" id="cmcont"/><br /><br />
<!--<label for="enviar"></label>-->
<input type="submit" name="envia" id="bentrar" value="Entrar" />
</form>
</div>
the point is "validation_errors()" function in here.
The 'can not enter' message is passed back after the rules have been passed. It is inside of the if statement when the form validation is true.
If you want this message to be displayed either load the message into the view, or set it as flash data.
Why not make the puede_entrar() model call into a custom callback form validation rule, then it can be added to the rules that are set.
Look here for information on custom callbacks.
This is how I would code your controller;
<?php
class Foo extends CI_Controller {
public function anuncios() {
// xxs_clean set globally in config
$this->form_validation->set_rules('drcorreo','Nombre de usuario', 'trim|required|min_length[5]|callback_puede_entrar');
// should use sha1 at least for hashing, see http://www.freerainbowtables.com/tables/
$this->form_validation->set_rules('contrasena','Contraseña', 'trim|required|min_length[8]|md5');
if($this->form_validation->run()) {
$this->load->model('modelo_bd');
$data['vanc']=$this->modelo_bd->datos();
$this->load->view('vancios',$data);
} else {
// redisplay form with validation errors
$this->load->view('indice');
}
}
public function puede_entrar($val) {
$this->load->model('modelo_usuarios');
if($this->modelo_usuarios->puede_entrar()) {
return TRUE;
} else {
$this->form_validation->set_message('puede_entrar', 'Las reglas no son validas.');
return FALSE;
}
}
}
The view (assuming you have autoloaded or have loaded $this->load->helper(array('form', 'url')); $this->load->library('form_validation'); elsewhere);
<div id="acformulario">
<form action="http://localhost/Pruebas/index.php/cindice/anuncios" method="post">
<?php echo form_error('drcorreo'); ?>
<label for="correo" id="dcorreo">Dirección de correo</label>
<input type="text" name="drcorreo" id="dcc"/><br /><br />
<label for="contrasenya" id="cont">Contraseña</label>
<?php echo form_error('contrasena'); ?>
<input type="password" name="contrasena" id="cmcont"/><br /><br />
<!--<label for="enviar"></label>-->
<input type="submit" name="envia" id="bentrar" value="Entrar" />
</form>
</div>
I have the problem of doing the validation of fields myself. Now there are 5-6 fields in the form. So I am checking each one in my controller, and if there is wrong i wish to load the view again and pass the error array to it.
I achieved the above functionality with this:
<html>
<head>
<title>My Form</title>
<meta http-equiv='Content-Type' content='text/html; charset=utf-8'>
</head>
<body>
<?php
echo $fullname;
?>
<?
echo form_open('/membership/register');
?>
<h5>Username</h5>
<input type="text" name="username" value="" size="50" />
<h5>Password</h5>
<input type="text" name="password" value="" size="50" />
<h5>Password Confirm</h5>
<input type="text" name="cpassword" value="" size="50" />
<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />
<h5>Mobile</h5>
<input type="text" name="mobile" value="" size="15" />
<h5>Home</h5>
<input type="text" name="home" value="" size="15" />
<h5>Full Name</h5>
<input type="text" name="fullname" value="" size="100" />
<br><br>
<div><input type="submit" value="Submit" /></div>
</form>
</body>
</html>
and in controller the code is:
if (preg_match('#[0-9]#',$fullname))
{
$errors['fullname'] = 'wrong name format!';
$this->load->view('register', $errors);
}
Now the real problem I have is if the many fields are wrong. I want to have $errors array passed to view and accessed there for all the values it contains. so I don't have to specify $fullname or $mobile to get the value. How can this be done? as to show the user everything missing in one go
First of all I advise using codeigniter's built in form validation class
Here is how I usually process my validation in the controller:
if ($this->input->post())
{
// process the POST data and store accordingly
$this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[5]|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[6]|xss_clean');
// the rest of your form fields validation can be set here
if ($this->form_validation->run() == FALSE)
{
// validation hasnt run or has errors, here just call your view
$this->load->view('same_view_file_with_the_form', $data);
}
else
{
// process the POST data upon correct validation
}
}
In my view file I call each error like this:
<h5>Username</h5>
<input type="text" name="username" value="" size="50" />
<span class="error-red"><?php echo form_error("username"); ?></span>
<h5>Password</h5>
<input type="text" name="password" value="" size="50" />
<span class="error-red"><?php echo form_error("password"); ?></span>
<h5>Password Confirm</h5>
<input type="text" name="cpassword" value="" size="50" />
<span class="error-red"><?php echo form_error("cpassword"); ?></span>
Do all your checks in the controller prior to binding errors into the view.
e.g.
$errors = array();
if (preg_match('#[0-9]#',$fullname))
{
$errors['fullname'] = 'wrong name format!';
}
if ( do_something_to_validate(mobile) )
{
$errors['mobile'] = 'invalid mobile';
}
// after checking everything do this
$this->load->view('register', $errors);
