How to get all flash messages in Codeigniter? - php

Question

I have a number of fields that have numerous validations from codeigniter validations. but now its showing one single validation error flash that is truly validated message
Here is my controller block code
public function customer_upd()
{
extract($_POST);
$err = '';
$date1 = $_POST['cust_upd_bd'];
$date2 = $_POST['cust_upd_dom'];
if($date2 != "") {
$datediff = (strtotime($date2) - strtotime($date1));
$res = floor($datediff / (60 * 60 * 24));
if ($res == " ") {
$err .= "Please Enter a Date";
} elseif ($res < 365) {
$err .= "Child marriage is prohibited";
}
if ($err != '') {
$_SESSION['dateerror'] = $err;
redirect('customer/edit/'.$_POST['ctmr_upd_id']);
}
}
$original_value1 = $this->db->query("SELECT customer_email FROM customer WHERE id = ".$_POST['ctmr_upd_id'])->row()->customer_email ;
if($_POST['cust_upd_email'] != $original_value1) {
$this->session->set_flashdata('add_failed','Email id must be unique & valid email address.');
$is_unique = '|is_unique[customer.customer_email]';
} else {
$is_unique = '';
}
$original_value2 = $this->db->query("SELECT customer_mobile FROM customer WHERE id = ".$_POST['ctmr_upd_id'])->row()->customer_mobile ;
if($_POST['cust_upd_mobile'] != $original_value2) {
$this->session->set_flashdata('add_failed','Mobile no must be unique & exact 10 digit numeric length. ');
$is_phoneunique = '|is_unique[customer.customer_mobile]';
} else {
$is_phoneunique = '';
}
$this->form_validation->set_rules('cust_upd_email', 'Email', 'required|valid_email|trim'.$is_unique);
$this->form_validation->set_rules('cust_upd_mobile', 'Mobile', 'required|exact_length[10]|is_natural|trim'.$is_phoneunique);
$this->form_validation->set_rules('cust_upd_name', 'Customer name', 'trim|required|min_length[3]|callback_customAlpha');
$this->session->set_flashdata('cust','The Customer field must be at least 3 characters in length. ');
$this->form_validation->set_rules('cust_upd_bd', 'Date of birth', 'regex_match[(0[1-9]|1[0-9]|2[0-9]|3(0|1))-(0[1-9]|1[0-2])-\d{4}]');
$this->form_validation->set_rules('cust_upd_dom', 'Date of marriage', 'regex_match[(0[1-9]|1[0-9]|2[0-9]|3(0|1))-(0[1-9]|1[0-2])-\d{4}]');
if ($this->form_validation->run() ) {
$userdata = $this->session->userdata();
$userId = $userdata['id'];
if (!$userId):
redirect(site_url());
endif;
extract($_POST);
print_r($_POST); exit;
$data = array(
'customer_name' => ucwords($_POST['cust_upd_name']),
'birth_date' => $_POST['cust_upd_bd'],
'anniversery_date' => $_POST['cust_upd_dom'],
'customer_mobile' => $_POST['cust_upd_mobile'],
'customer_email' => $_POST['cust_upd_email'],
'status' => $_POST['cust_upd_status'],
'address' => $_POST['ctmr_address'],
'cat_type' => $_POST['file_cat']
);
$userdata = $this->session->userdata();
$userId = $userdata['id'];
$this->db->where('user_id', $userId);
$this->db->where('id', $_POST['file_cat']);
$this->db->where('cat_status', 'Enable');
$get_file = $this->db->get('category');
$res_file = $get_file->num_rows();
if($res_file >0){
$userdata = $this->session->userdata();
$userId = $userdata['id'];
$this->db->where('user_id', $userId);
$this->db->where('id', $_POST['ctmr_upd_id']);
$ctmr_upd = $this->db->update('customer', $data);
} else {
$this->session->set_flashdata('edit_failed','Something went wrong.');
redirect('customer/edit/'.$_POST['ctmr_upd_id']);
}
redirect(site_url() . '/customer');
} else {
redirect('customer/edit/'.$_POST['ctmr_upd_id']);
}
}
And here is my view code
<div class="row">
<div class="col-md-12 col-sm-12 col-xs-12">
<?php if($error = $this->session->flashdata('add_failed')): ?>
<div class="row">
<div class="col-lg-9">
<div class="alert alert-dismissible alert-danger col-md-offset-4">
<?php echo $error; ?>
</div>
</div>
</div>
<?php endif; ?>
<?php if($error1 = $this->session->flashdata('edit_failed')): ?>
<div class="row">
<div class="col-lg-9">
<div class="alert alert-dismissible alert-danger col-md-offset-4">
<?php echo $error1; ?>
</div>
</div>
</div>
<?php endif; ?>
<?php if($error2 = $this->session->flashdata('cust')): ?>
<div class="row">
<div class="col-lg-9">
<div class="alert alert-dismissible alert-danger col-md-offset-4">
<?php echo $error2; ?>
</div>
</div>
</div>
<?php endif; ?>
<?php if($_SESSION['dateerror']){
echo '<div class="alert alert-danger col-sm-7 col-md-offset-3" role="alert">'.$_SESSION['dateerror'].'</div>';
unset($_SESSION['dateerror']);
}
?>
And here is a snap
Whenever i tries to submit with their validate data, its showing this above error flash message.
i tried many times but unable to achieve any success.
Please guide me and tell me where am i going wrong?

Answer 1

Use below mentioned code to retrieve all flashdata.
$this->session->flashdata();
It will return array with all flashdata, simply omit the key parameter.
Let me know if it not works.
