I am a beginner in php.Whenever i try to implement Pager class in pear i get this error
Non-static method Pager::factory() should not be called statically in D:\xampp\htdocs\sam\temp\youtube_playlist.php on line 21
My code is
<?php
include("header.php");
include("connect.php");
//connect to db to get video data
$qr = mysql_query("SELECT vid FROM videos",$con);
$data="";
while($row = mysql_fetch_array($qr))
{
$data[]=$row['vid'];
}
//pageing
require('Pager/Pager.php');
$pg_op= array(
'itemData'=>$data,
'append' => true,
'perPage' => 3,
'mode' => 'Sliding',
'delta' => 2
);
$pager = Pager::factory($pg_op);
$pdata = $pager -> getPageData();
$plinks = $pager -> getLinks();
//Display the video
foreach ($pdata as $vd)
{
?>
<iframe width="510" height="265" src="http://www.youtube.com/embed/<?php echo $vd; ?>" frameborder="0" allowfullscreen></iframe>
<?php
}
echo "<br />";
echo $plinks['all'];
include("footer.php");
?>
Please help
I just had the same issue.
This Pager class seems to be outdated. If you still want to use it, just suppress error by prepending the command with #
$pager = #Pager::factory($pg_op);

Fairly new to codeigniter and i just cant find the right way to load an array into a view.
for example lets say i have an array like
$data = [
'title' => 'my title,
'desc' => 'my desc,
];
i can pass that to my view like
return view('myview',$data);
then simply echo it out in my view like
<h1><?= $title ?></h1>
<p><?= $desc ?></p>
That works fine. but now lets say i have another array like :
$moredata =[
'more_data' => 'some more data',
'even_more_data' => 'even more data',
];
if i try to add that to my data array like
$data[] = $moredata
when i try to access 'more_data' or 'even_more_data' in my view like
<?= $more_data ?>
i get a undefined variable error for $moredata. So how do i access the variables within that new array? am i declaring them properly?
also if i wanted to loop through the secondary array how do i do that. trying
<?php foreach($moredata as $items){ ?>
<li><?php echo $items; ?></li>
<?php } ?>
also gives me an undefined variable error for $moredata
any help on how to do this correctly in codeigniter 4 appreciated.
Codeigniter uses the key of the array you're giving him to create variables name.
You should init it this way :
$moredata =[
'more_data' => 'some more data',
'even_more_data' => 'even more data',
];
// key of your array will be a variable name in your view
$data['my_var_name_in_view'] = $moredata
return view('myview',$data);
Then in your view you will be able to perform this :
<?php foreach($my_var_name_in_view as $items){ ?>
<li><?php echo $items; ?></li>
<?php } ?>
I want to save the image path through a form, but the path of the image is not saved.
i've tried with this but i don't know where to put the code
MultimediaController:
public function add()
{
$multimedia = $this->Multimedia->newEntity();
if ($this->request->is('post')) {
$multimedia = $this->Multimedia->patchEntity($multimedia, $this->request->data);
$file = $_FILES['url'];
$path = 'files/' .$_FILES['url']['name'];
move_uploaded_file($this->data['url']['tmp_name'], $path);
if ($this->Multimedia->save($multimedia)) {
$this->Flash->success('The multimedia has been saved.');
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error('The multimedia could not be saved. Please, try again.');
}
}
$categories = $this->Multimedia->Categories->find('list', ['limit' => 200]);
$this->set(compact('multimedia', 'categories'));
$this->set('_serialize', ['multimedia']);
}
add.ctp
<?= $this->Form->create($multimedia, array('enctype' => 'multipart/form-data')); ?>
<fieldset>
<legend><?= __('Add Multimedia') ?></legend>
<?php
echo $this->Form->input('title');
echo $this->Form->input('description');
echo $this->Form->input('mime_type');
echo $this->Form->input('filename');
echo $this->Form->input('url', array('type' => 'file'));
echo $this->Form->input('category_id', ['options' => $categories]);
echo $this->Form->input('created_by');
?>
</fieldset>
<?= $this->Form->button(__('Submit')) ?>
<?= $this->Form->end() ?>
I'm new to cakephp 3 and am a bit lost. Please help.
Update:
already achieved to save the image:
$file = $_FILES['url'];
$path = "webroot\\files\\" .$_FILES['url']['name'];
print_r($file);
move_uploaded_file($_FILES['url']['tmp_name'], $path);
if ($this->Multimedia->save($multimedia)) {
$this->Flash->success('The multimedia has been saved.');
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error('The multimedia could not be saved. Please, try again.');
}
But now the "url" is not saved in the database
I hope this help you, the script here has some improvements like using the short deceleration for arrays:
The Controller code:
//don't forget to import the Folder class
use Cake\Filesystem\Folder;
public function add()
{
$multimedia = $this->Multimedia->newEntity();
if ($this->request->is('post')) {
$multimedia = $this->Multimedia->patchEntity($multimedia, $this->request->data);
//upload script start here
$mm_dir = new Folder(WWW_ROOT . 'upload_dir', true, 0755);
$target_path = $mm_dir->pwd() . DS . $this->request->data('url.name');
move_uploaded_file($this->request->data('url.tmp_name'), $target_path);
//save the file name in the field 'url'
$multimedia->url= $this->request->data('url.name');
//the script ends here
if ($this->Multimedia->save($multimedia)) {
// ............
} else {
// .........
}
}
// ..........
}
add.ctp // improvement
<?= $this->Form->create($multimedia, ['type' => 'file']); ?>
echo $this->Form->input('url', ['type' => 'file']);
In wordpress, when a post category (or tag) is clicked, all posts that match the clicked category (or tag) is returned, because of <?php the_content(); ?>
In my case, every post has an image in it, so how can I only fetch the images when a category (or tag) is clicked? I'm not familiar what code I need to use.
Update: I'm trying not to use plugins. My apologies for not mentioning that earlier. What I'm trying to achieve is something like The Sartorialist - All posts have images, click on any category (or tag) associated with any post and only images are fetched.
Update 2: I tried this:
<?php
$args = array(
'post_type' => 'attachment',
'numberposts' => -1,
'post_status' => null,
'post_parent' => $post->ID
);
$attachments = get_posts( $args );
if ( $attachments ) {
foreach ( $attachments as $attachment ) {
echo '<li>';
echo wp_get_attachment_image( $attachment->ID, 'full' );
echo '</li>';
}
}
?>
The only weird thing is, and I'm trying to figure out, another image from the media library also shows up, without it being in any of my posts.
I also found this plugin which is very close to what I want, but unfortunately it has to be in a separate page, not the in category page.
You can achieve this with something like this:
<?php
function getImage($num) {
global $more;
$more = 1;
$link = get_permalink();
$content = get_the_content();
$count = substr_count($content, '<img');
$start = 0;
for($i=1;$i<=$count;$i++) {
$imgBeg = strpos($content, '<img', $start);
$post = substr($content, $imgBeg);
$imgEnd = strpos($post, '>');
$postOutput = substr($post, 0, $imgEnd+1);
$postOutput = preg_replace('/width="([0-9]*)" height="([0-9]*)"/', '',$postOutput);;
$image[$i] = $postOutput;
$start=$imgEnd+1;
}
if(stristr($image[$num],'<img')) { echo ''.$image[$num].""; }
$more = 0;
}
?>

How can i use flash messenger in zend freamwork 2? Session documentation is not yet. Anyone know it? But session libraries are there.
Update :
Zend Framework new release added FlashMessenger View Helper , found in path /library/Zend/View/Helper/FlashMessenger.php
FlashMessenger.php
Old answer :
I have written a custom view helper, for printing flash messages
In /module/Application/Module.php
public function getViewHelperConfig()
{
return array(
'factories' => array(
'flashMessage' => function($sm) {
$flashmessenger = $sm->getServiceLocator()
->get('ControllerPluginManager')
->get('flashmessenger');
$message = new \My\View\Helper\FlashMessages( ) ;
$message->setFlashMessenger( $flashmessenger );
return $message ;
}
),
);
}
Create a custom view helper in /library/My/View/Helper/FlashMessages.php
namespace My\View\Helper;
use Zend\View\Helper\AbstractHelper;
class FlashMessages extends AbstractHelper
{
protected $flashMessenger;
public function setFlashMessenger( $flashMessenger )
{
$this->flashMessenger = $flashMessenger ;
}
public function __invoke( )
{
$namespaces = array(
'error' ,'success',
'info','warning'
);
// messages as string
$messageString = '';
foreach ( $namespaces as $ns ) {
$this->flashMessenger->setNamespace( $ns );
$messages = array_merge(
$this->flashMessenger->getMessages(),
$this->flashMessenger->getCurrentMessages()
);
if ( ! $messages ) continue;
$messageString .= "<div class='$ns'>"
. implode( '<br />', $messages )
.'</div>';
}
return $messageString ;
}
}
then simple call from layout.phtml , or your view.phtml
echo $this->flashMessage();
Let me show example of controller action
public function testFlashAction()
{
//set flash message
$this->flashMessenger()->setNamespace('warning')
->addMessage('Mail sending failed!');
//set flash message
$this->flashMessenger()->setNamespace('success')
->addMessage('Data added successfully');
// redirect to home page
return $this->redirect()->toUrl('/');
}
In home page, it prints
<div class="success">Data added successfully</div>
<div class="warning">Mail sending failed!</div>
Hope this will helps !
i have written a post about this some time ago. You can find it right here
Basically you use it just the same like earlier.
<?php
public function commentAction()
{
// ... display Form
// ... validate the Form
if ($form->isValid()) {
// try-catch passing data to database
$this->flashMessenger()->addMessage('Thank you for your comment!');
return $this->redirect()->toRoute('blog-details'); //id, blabla
}
}
public function detailsAction()
{
// Grab the Blog with given ID
// Grab all Comments for this blog
// Assign the view Variables
return array(
'blog' => $blog,
'comments' => $comments,
'flashMessages' => $this->flashMessenger()->getMessages()
);
}
Then in your .phtml file you do it like this:
// details.phtml
<?php if(count($flashMessages)) : ?>
<ul>
<?php foreach ($flashMessages as $msg) : ?>
<li><?php echo $msg; ?></li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
Obviously this isn't all too handy, as you have to do this for every single .phtml file. Therefore doing it within the layout you have to do it at best like the following:
<?php
// layout.phtml
// First get the viewmodel and all its children (ie the actions viewmodel)
$children = $this->viewModel()
->getCurrent()
->getChildren();
$ourView = $children[0];
if (isset($ourView->flashMessages) && count($ourView->flashMessages)) : ?>
<ul class="flashMessages">
<?php foreach ($ourView->flashMessages as $fMessage) : ?>
<li><?php echo $fMessage; ?></li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
If you need further description, please see my blog, but i guess the code itself is pretty clear (apart frmo the layout.phtml example). Alternatively you're always free to write your own view helper to have it look a little cleaner inside your view-templates.
How to grab Flashmessenger’s messages in a View Helper – sharing code as requested by Sam.
The View helper should implement the ServiceManagerAwareInterface interface and related methods. The plugin will now have access to a Service Manager which we can use to get the Service Locator and ultimately access to the Flash Messenger.
I’ve not touched this code since I initially wrote it – so there may be a more elegant way of doing this.
protected function getMessages()
{
$serviceLocator = $this->getServiceManager()->getServiceLocator();
$plugin = $serviceLocator->get('ControllerPluginManager');
$flashMessenger = $plugin->get('flashmessenger');
$messages = $flashMessenger->getMessages();
// Check for any recently added messages
if ($flashMessenger->hasCurrentMessages())
{
$messages += $flashMessenger->getCurrentMessages();
$flashMessenger->clearCurrentMessages();
}
return $messages;
}
And calling getMessages() from within the plugin should return an array of messages that can be passed to a partial and rendered.
Add code below to the view to render error messages:
<?php echo $this->flashmessenger()
->setMessageOpenFormat('<div class="alert alert-danger"><ul%s><li>')
->setMessageCloseString('</li></ul></div>')
->render('error')
; ?>
In previous request, make sure you created an error message by running code below in your controller:
$this->flashmessenger()->addErrorMessage('Whops, something went wrong...');
I have a form that submits data to a database in a CodeIgniter app (CI v. 2.0.2). We are allowing users to "edit" records by having them resubmit a record with new values and then doing an update. On submit, the form calls the vote controller's create method. Inside the create method, we check to see if there's already a record based on an entry code and the user's ID. If there is, we update; otherwise we create a new record. The creation works just fine; it's only the update I'm having an issue with. Here's the code.
view
<div id="vote_form">
<?php
$hidden = array('dot_judge_id' => $this->session->userdata('dot_judge_id'));
echo form_open('vote/create');
$entry_code_data = array(
'name' => 'entry_code',
'id' => 'entry_code',
'value' => set_value('entry_code')
);
echo form_hidden($hidden);
$score_options = array('1'=>'1 (lowest)', '2'=>'2','3'=>'3', '4'=>'4','5'=>'5 (highest)');
?>
<p><label for="entry_code">Entry code: </label><?php echo form_input($entry_code_data); ?></p>
<p><label for="q1">Question 1: </label><?php echo form_dropdown('q1', $score_options, ''); ?></p>
<p><label for="q2">Question 2: </label><?php echo form_dropdown('q2', $score_options, ''); ?></p>
<p><label for="q3">Question 3: </label><?php echo form_dropdown('q3', $score_options, ''); ?></p>
<p><label for="q4">Question 4: </label><?php echo form_dropdown('q4', $score_options, ''); ?></p>
<p><label for="q5">Question 5: </label><?php echo form_dropdown('q5', $score_options, ''); ?></p>
<p><?php echo form_submit('submit', 'Submit vote'); ?></p>
<?php echo form_close(); ?>
<?php echo validation_errors(); ?>
</div>
controller
function create() {
$id = $this->input->post('entry_code');
$judge_id = $this->input->post('dot_judge_id');
$data = array(
'entry_code' => $id,
'dot_judge_id' => $judge_id,
'q1' => $this->input->post('q1'),
'q2' => $this->input->post('q2'),
'q3' => $this->input->post('q3'),
'q4' => $this->input->post('q4'),
'q5' => $this->input->post('q5'),
);
//first check to see if there's already a record for this judge/entry
//if so, update. Otherwise, insert
$vote_id = $this->vote_model->getEntryById($id, $judge_id);
if($vote_id) {
log_message('debug', 'vote id exists: '.$vote_id);
$this->vote_model->updateRecord($data, $vote_id);
}
else {
log_message('debug', 'vote id does not exist; creating new');
$this->vote_model->createRecord($data);
}
/*
after submission, go to another page that gives choices - review entries, submit another entry, log out
*/
$data['msg'] = "Entry submitted";
$this->menu();
}
model
function getEntryByID($id, $judge_id) {
//determine if record already exists for entry/judge
$sql = 'SELECT vote_id from dot_vote WHERE entry_code = ? AND dot_judge_id = ?';
$query = $this->db->query($sql, array($id, $judge_id));
if($query->num_rows() == 1) {
$row = $query->row();
return $row->vote_id;
}
else {
return false;
}
}
function createRecord($data) {
$this->db->insert('dot_vote', $data);
return;
}
function updateRecord($data, $vote_id) {
log_message('debug', 'vote id is passed: '.$vote_id);
$this->db->where('vote_id', $vote_id);
$this->update('dot_vote', $data);
}
I know it's making it into the updateRecord method because the log_message output is in my log file displaying the correct vote_id (the auto-increment field of the returned record). But what I get in the browser is the following:
Can anyone point me in the right direction here? I have error display on in my config file, and have gotten SQL errors when they occur, so I don't think this is a SQL error. But I have no idea what could be happening in that tiny little function that's causing this. My next step is to skip the active record update and just use a standard query, but I'd like to know what's causing the problem here, even if I can get it to work the other way.
This line stood out:
$this->update('dot_vote', $data);
Do you mean this?
$this->db->update('dot_vote', $data);
