Codeigniter & JQuery validation problem
hello everyone , i am trying to do some form validation using Condeiginter and Jquer's AJAX .
the view file
PHP Code:
</script>
<script type = "text/javascript">
$(document).ready(function(){
var dest = '<?php echo site_url("/users/fieldUpdate");?>';
$('.item').editable(dest, {
indicator : 'Saving...',
tooltip : 'Click to edit...',
id : 'fieldName',
name : 'fieldValue',
submit : 'Save',
cancel : 'Undo',
ajaxoptions: {
dataType : 'json',
success : function(data){
$("#response").html(data.msg).show(1000).slideDown();
}
}
});
});
</script>
<div id="response" class ="hidden">
</div>
<label for ="username">Username : </label>
<br>
<h4 id="username" class ="item"><?php echo $userDetails['username'];?></h4>
<br>
<h4 id="password" class ="item"><?php echo $userDetails['password'];?></h4>
<br>
<h3 id="email"class ="item"><?php echo $userDetails['email'];?></h3>
<h4 id="quote"class ="item"><?php echo $userDetails['quote'];?></h4>
<br>
<h4 id="avatarH4"><?php echo $userDetails['avatar'];?></h4>
the controller
PHP Code:
public function fieldUpdate(){
if(isset($_POST['fieldName']) && isset($_POST['fieldValue'])){
// setting rules for CI validation class
$rules = array(
array(
'field' => 'username',
'label' => 'hblXhbl',
'rules' => 'min_length[6]'
),
array(
'field' => 'password',
'label' => 'Password',
'rules' => 'required|min_length[5]|max_length[45]'
),
array(
'field' => 'avtar',
'label' => 'Avtar',
'rules' => 'min_length[5]|max_length[105]|valid_url'
),
array(
'field' => 'quote',
'label' => 'Quote',
'rules' => 'min_length[5]|max_length[100]'
)
);
// getting proper rule
for($i=0;$i<5;$i++){
if($_POST['fieldName'] == $rules[$i]['field']){
// must be wrapped in an array to be in a valid format
$fieldRules = array($rules[$i]);
break;
}
}
$vArray = $this->form_validation->metValidate($fieldRules);
if($vArray[0]){
// an array of DB field name and the new value of it
$updateArray = array($_POST['fieldName']=>$_POST['fieldValue']);
// no user can reach here untill he was signed in
$userId = $this->session->userdata("userid");
// update userData in the DB
$this->musers->updateUserdata($updateArray,$userId);
// return a success msg
$result = array("status"=>'success','msg'=>'userData updated !');
}else{
$result = array("status"=>'fail','msg'=>$vArray["validationErrors"]);
}
echo json_encode($result);
}
}
// a function used to update user data
public function personals(){
// check if the user is logged in
if(isLogged()){
$myArray = whichStatus();
$data['status'] = $myArray[0];
$data['username'] = $myArray[1];
// the main view (a view contains user's personal information updatable using fieldUpdate() method)
$data['main']="Vpersonals";
$data['userDetails'] = $this->musers->getUserById(1,true);
$this->load->view("Vmain",$data);
}else{
// user is not logged in
redirect("/","refresh");
}
}
the validation method METvalidate()
PHP Code:
public $uniqueErrors = array();
// rules is an array of rules passed to the form validation class
// uniques is an array of fields that must be unique
public function metValidate($rules,$uniques = false){
$this->CI->form_validation->set_rules($rules);
if($this->CI->form_validation->run()==false){
return array(false,"validationErrors"=>validation_errors());
}
// if no errors related with form validation then start checking uniques
if($uniques){
$this->CI->load->model("mglobal");
$tableName = $uniques['tableName'];
// detecting non-unique fields
foreach($uniques['uniques'] as $key=>$value){
if(!$this->CI->mglobal->isUnique($tableName,$key,$value)){
$this->uniqueErrors[] = $value;
}
}
if(count($this->uniqueErrors)){
return array(false,"uniqueErrors"=>$this->uniqueErrors);
}
}
// if they are all fine just return true
return array(true);
}
the result that i get when executing this code is
1- when updating the username always i get userData updated as a 'msg' in the returned JSON object (even if the new username is lower the specified length or longer than it or even left blank !!).
2- any update in the password field results in the same message that says "The Password field is required".
so where is the problem !! |
