I am using Laravel Translatables. But when I execute I got an error like Call to a member function hasTranslation() on null. Here is my code.
<?php
if($slider->product->hasTranslation($locale))
{
$type = $slider->product->translate($locale)->product_name;
}
else{
$type = $slider->product->translate('en')->product_name;
} //echo $type; exit;
?>
$slider->product is not null and $locale has value 'en'
This code is working fine yesterday, the only change I made is, from the admin panel I just removed the required validation from add product field.
Check the setup of your relation $slider->product is not null
and the model has use Translatable trait
there is a helper method called optional()
optional($slider->product)->hasTranslation($locale)
this method will avoid to throw an exception.
NOT RECOMMENDED TO USE IT (optional()) IF $slider->product MUST HAVE A VALUE
just shortcut for clean code
if(optional($slider->product)->hasTranslation($locale))
$type = optional($slider->product)->translate($locale)->product_name;
else
$type = optional($slider->product)->translate('en')->product_name;
I fixed this problem with another if condition. Modified code is
<?php if(!empty($slider->product)) {
if($slider->product->hasTranslation($locale))
{
$type = $slider->product->translate($locale)->product_name;
}
else{
$type = $slider->product->translate('en')->product_name;
}
}
?>

I have situation where codeigniter shows database Error Number 1048. It seems Values NULL but when I try to check it usign var_dump($_POST) Values are not NULL.
Controller : Jurusan.php
public function simpan()
{
$this->form_validation->set_rules('code','Kode','required|integer');
$this->form_validation->set_rules('jurusan','Jurusan','required');
$this->form_validation->set_rules('singkatan','Singkatan','required');

if($this->form_validation->run() == FALSE)
{
$isi['content'] = 'jurusan/form_tambahjurusan';
$isi['judul'] = 'Master';
$isi['sub_judul'] = 'Tambah Jurusan';
$this->load->view('tampilan_home',$isi);
} else {

}
}
Model : model_jurusan.php

{
$this->db->where('kd_prodi',$key);
$this->db->update('prodi',$data);
}
public function getinsert($data)
{
$this->db->insert('prodi',$data);
}
}
Here is the error shown :
Here is the database structure :
You have a wrong syntax in these lines:
$key = $this->input->post('code');
$data['kd_prodi'] = $this->input->post['code']; // <-- use ('code')
$data['prodi'] = $this->input->post['jurusan']; // <-- use ('jurusan')
Change this to
$this->input->post['array_key'];
this
$this->input->post('array_key');
Read : Input Class in Codeigniter
Well the problem lies in your way of accepting input parameters.
$this->input->post
is a method which accepts the variable name, not an array. So all the input parameters need to be passed as a function parameter to post method. These lines need to be altered to.
$data['kd_prodi'] = $this->input->post('code');
$data['prodi'] = $this->input->post('jurusan');
$data['singkat'] = $this->input->post('singkatan');
$data['ketua_prodi'] = $this->input->post('ketua');
$data['nik'] = $this->input->post('nik');
$data['akreditasi'] = $this->input->post('akreditasi');
Hope this solves the problem.
EDIT:
You did a var_dump($_POST) which works as it is supposed to and it will read the values of the post parameters. So either you fetch the parameters from $_POST array, or you use the $this->input->post() method. But I would suggest using the $this->input->post() method as it provides additional sanitization such as xss attack handling etc, which could be turned on an off from the config.
i have tried your code...it works. I think there some mistakes in your <input> tags, You must use <input name=""> not <input id=""> or something else. Hope it can help you out
You are try to get value from post is wrong. You should use at this way
$_POST['array value'];
I Am trying to insert data in DB,But somehow NULL is inserted in DB
Here Is My Controller
foreach($this->input->post('resume_id') as $key =>$value ){

$ResumeInsert[$key]['Skills'] = $Resume['Skills'][$key];
if(isset($Resume['id'][$key]) ){
$Key_Resume__ExistIDs[]=$Resume['id'][$key];

This is Insert Query
function insert_tbl_resume($id,$arrtbl_resume){
$this->db->insert_batch('tbl_resume', $arrtbl_resume);
}
In Above Code,Null Value inserted In DB.
when i Print above query,it displays blank
Any Help Please?
You should use form_validation library. I'm giving you an example, you can edit and use it.
In autoload.php, edit $autoload['libraries'] = array(); line to:
$autoload['libraries'] = array('form_validation');
Then, use form_validation in your controller file. For example:
$this->form_validation->set_rules('resume_keyid', 'Resume ID', 'required');
if ($this->form_validation->run() == FALSE)
{
$this->index() // if there is an error, user will redirect to this function
}
else
{
$this->Resume_model->ProcessData();
}
Also please use $this->input->post('resume_keyid', TRUE); structure in your model. "TRUE" means "open XSS filter". Because in CI 3, it comes off as default. If you don't want it, just remove. If you use CI 2, you don't need to add "TRUE".
A few suggestions:
1 - Don't use camelization when you name functions. For example; use process_data() instead of processData()
2 - Check CI Form Validation Document for all details (E.g. all references)
3 - I think you can use $this->db->insert();, just create an array and POST it. If you make it, you'll understand what's wrong.
I do not want to be asking a question that has already been answered, however I have done a ton of research and I am stuck. Any help would be appreciated.
I am trying to query and add database results to OpenCart's addproduct.tpl
In the MODEL file I have:
public function units() { //function that gets database info and returns it
$unit_variables = $this->db->query("SELECT unit FROM ". DB_PREFIX ."
weight_class_description");
if (!$unit_variables) {
die(mysql_error());
}
else {
foreach ($unit_variables->rows as $temp_var) {
print_r($temp_var['unit'], true);
}
}
}
In the CONTROLLER file I have:
$this->load->model('catalog/product'); //where my function is located
$this->model_catalog_product->units();
$weight_variables = units();
if (isset($this->request->post['weight_variables'])){
$this->data['weight_variables'] = $this->request->post['weight_variables'];
}
In the VIEW I have:
<?php echo $weight_variables ?>
I get the following error:
Call to undefined function units() in /path/to/controller/file on line etc.
Note: When I print_r($temp_var); instead of returning print_R($temp_var, true) and delete these lines of code $weight_variables = units(); if (isset($this->request->post['weight_variables'])){ $this->data['weight_variables'] = $this->request->post['weight_variables'] } in the controller file my model file will display the query results on the addproduct.tpl
units() is a METHOD of your object, yet you're calling it as a standalone regular function:
$weight_variables = units();
^^^^^^^
Shouldn't it be:
$weight_variables = $this->model_catalog_product->units();
instead? And note that as-written, your method doesn't actually return anything, so $weight_variables will simply get assigned null..
I've read through the tutorials/reference of the Form-Component in Zend-Framework 2 and maybe I missed it somehow, so I'm asking here.
I've got an object called Node and bound it to a form. I'm using the Zend\Stdlib\Hydrator\ArraySerializable-Standard-Hydrator. So my Node-object has got the two methods of exchangeArray() and getArrayCopy() like this:
class Node
{
public function exchangeArray($data)
{
// Standard-Felder
$this->node_id = (isset($data['node_id'])) ? $data['node_id'] : null;
$this->node_name = (isset($data['node_name'])) ? $data['node_name'] : null;
$this->node_body = (isset($data['node_body'])) ? $data['node_body'] : null;
$this->node_date = (isset($data['node_date'])) ? $data['node_date'] : null;
$this->node_image = (isset($data['node_image'])) ? $data['node_image'] : null;
$this->node_public = (isset($data['node_public'])) ? $data['node_public'] : null;
$this->node_type = (isset($data['node_type'])) ? $data['node_type']:null;
$this->node_route = (isset($data['node_route'])) ? $data['node_route']:null;
}
public function getArrayCopy()
{
return get_object_vars($this);
}
}
In my Controller I've got an editAction(). There I want to modify the values of this Node-object. So I am using the bind-method of my form. My form has only fields to modify the node_name and the node_body-property. After validating the form and dumping the Node-object after submission of the form the node_name and node_body-properties now contain the values from the submitted form. However all other fields are empty now, even if they contained initial values before.
class AdminController extends AbstractActionController
{
public function editAction()
{
// ... more stuff here (getting Node, etc)
// Get Form
$form = $this->_getForm(); // return a \Zend\Form instance
$form->bind($node); // This is the Node-Object; It contains values for every property
if(true === $this->request->isPost())
{
$data = $this->request->getPost();
$form->setData($data);
// Check if form is valid
if(true === $form->isValid())
{
// Dumping here....
// Here the Node-object only contains values for node_name and node_body all other properties are empty
echo'<pre>';print_r($node);echo'</pre>';exit;
}
}
// View
return array(
'form' => $form,
'node' => $node,
'nodetype' => $nodetype
);
}
}
I want to only overwrite the values which are coming from the form (node_name and node_body) not the other ones. They should remain untouched.
I think a possible solution would be to give the other properties as hidden fields into the form, however I don't wanna do this.
Is there any possibility to not overwrite values which are not present within the form?
I rechecked the code of \Zend\Form and I gotta be honest I just guessed how I can fix my issue.
The only thing I changed is the Hydrator. It seems that the Zend\Stdlib\Hydrator\ArraySerializable is not intended for my case. Since my Node-Object is an object and not an Array I checked the other available hydrators. I've found the Zend\Stdlib\Hydrator\ObjectProperty-hydrator. It works perfectly. Only fields which are available within the form are populated within the bound object. This is exactly what I need. It seems like the ArraySerializable-hydrator resets the object-properties, because it calls the exchangeArray-method of the bound object (Node). And in this method I'm setting the non-given fields to null (see code in my question). Another way would propably be to change the exchangeArray-method, so that it only sets values if they are not available yet.
So the solution in the code is simple:
$form = $this->_getForm();
$form->setHydrator(new \Zend\Stdlib\Hydrator\ObjectProperty()); // Change default hydrator
There is a bug in the class form.php, the filters are not initialized in the bindvalues method just add the line $filter->setData($this->data);
it should look like this after including the line
public function bindValues(array $values = array())
{
if (!is_object($this->object)) {
return;
}
if (!$this->hasValidated() && !empty($values)) {
$this->setData($values);
if (!$this->isValid()) {
return;
}
} elseif (!$this->isValid) {
return;
}
$filter = $this->getInputFilter();
$filter->setData($this->data); //added to fix binding empty data
switch ($this->bindAs) {
case FormInterface::VALUES_RAW:
$data = $filter->getRawValues();
break;
case FormInterface::VALUES_NORMALIZED:
default:
$data = $filter->getValues();
break;
}
$data = $this->prepareBindData($data, $this->data);
// If there is a base fieldset, only hydrate beginning from the base fieldset
if ($this->baseFieldset !== null) {
$data = $data[$this->baseFieldset->getName()];
$this->object = $this->baseFieldset->bindValues($data);
} else {
$this->object = parent::bindValues($data);
}
}
to be precious it is line no 282 in my zf2.0.6 library
this would fix your problem, this happen only for binded object situation
I ran into the same problem, but the solution of Raj is not the right way. This is not a bug as for today the code remains still similar without the 'fix' of Raj, adding the line:
$filter->setData($this->data);
The main problem here is when you bind an object to the form, the inputfilter is not stored inside the Form object. But called every time from the binded object.
public function getInputFilter()
...
$this->object->getInputFilter();
...
}
My problem was that I created every time a new InputFilter object when the function getInputFilter was called. So I corrected this to be something like below:
protected $filter;
...
public function getInputFilter {
if (!isset($this->filter)) {
$this->filter = new InputFilter();
...
}
return $this->filter;
}
I ran into the same issue today but the fix Raj suggested did not work. I am using the latest version of ZF2 (as of this writing) so I am not totally surprised that it didn't work.
Changing to another Hydrator was not possible as my properties are held in an array. Both the ObjectProperty and ClassMethods hydrators rely on your properties actually being declared (ObjectProperty uses object_get_vars and ClassMethods uses property_exists). I didn't want to create my own Hydrator (lazy!).
Instead I stuck with the ArraySerializable hydrator and altered my exchangeArray() method slightly.
Originally I had:
public function exchangeArray(array $data)
{
$newData = [];
foreach($data as $property=>$value)
{
if($this->has($property))
{
$newData[$property] = $value;
}
}
$this->data = $newData;
}
This works fine most of the time, but as you can see it blows away any existing data in $this->data.
I tweaked it as follows:
public function exchangeArray(array $data)
{
$newData = [];
foreach($data as $property=>$value)
{
if($this->has($property))
{
$newData[$property] = $value;
}
}
//$this->data = $newData; I changed this line...
//to...
$this->data = array_merge($this->data, $newData);
}
This preserves any existing keys in $this->data if they are missing from the new data coming in. The only downside to this approach is I can no longer use exchangeArray() to overwrite everything held in $this->data. In my project this approach is a one-off so it is not a big problem. Besides, a new replaceAllData() or overwrite() method is probably preferred in any case, if for no other reason than being obvious what it does.
so im making homepage with three languages.
I am using switch method, here is code -
public function languages()
{
if (isset($_GET['lang']) && $_GET['lang'] != '')
{
$_SESSION['lang'] = $_GET['lang'];
}
else
{
$_SESSION['lang'] = 'en_EN';
}
switch($_SESSION['lang'])
{
case 'en_EN': require_once('language/lang.eng.php');break;
case 'lv_LV': require_once('language/lang.lv.php');break;
case 'ru_RU': require_once('language/lang.ru.php');break;
default: require_once('language/lang.eng.php');
}
}
public function translate($txt)
{
global $text;
return $text[$txt];
}
and it should display in index.php file like this -
<?php $index->translate('search'); ?>
but the problem is that it shows no errors, no notices, no warnings and no translated or default text.
I included function languages() , maybe you can help me with this problem?
EDIT:
im calling $language at start of index.php file - <?php require_once('class.index.php'); $index = new index; $index->languages(); ?> and $text is defined in lang.eng.php; lang.lv.php and lang.ru.php file.
Since you're using a class, I think it's better to use properties instead of globals, it will be easier in future mantainance. Create a class variable holding $text and use that
class Index {
var $text;
public function languages()
{
require(".....");
$this->text = $text;
}
public function translate($txt)
{
if(isset($this->text[$txt]))
{
return $this->text[$txt];
}
else
{
return "no translation";
}
}
}
$index = new Index;
$index->languages();
echo $index->translate('search');
type
<?php echo $index->translate('search'); ?>
Check first whether the session is initialized or not and also place the languages() function call before the translate so that it loads the language prior to translation and also put error_reporting(E_ALL) at top so that any error suppresion will be be removed and also put echo the returned result of translate statement
