I try to call an echo inside the shortcode.
The line of code is like this:
<?php echo do_shortcode('[audio src="<?php echo $audio; ?>"]'); ?>
The complete code is like this:
<?php if(get_post_meta($post->ID, '_format_audio_embed', true)!=''){
$audio = get_post_meta($post->ID, '_format_audio_embed', true);
} else {
$audio = '';
}
?></h1>
<?php echo do_shortcode('[audio src="<?php echo $audio; ?>"]'); ?>
My code did not work. Am I missing something?
Why are you using PHP inside PHP? Try to concat:
<?php echo do_shortcode('[audio src="'.$audio.'"]'); ?>

I have the follow form in Codeigniter:
The controller:
public function item($alias = NULL){
$this->load->helper('form');
$this->load->library('form_validation');
$data['title'] = 'Edit menu';
$data['menu_item'] = $this->menu_model->get_menu($alias);
$data['articole'] = $this->menu_model->get_articole();
$data['menuactive'] = $this->menu_model->get_menuactiv();
$data['errors'] = $this->form_validation->error_array();
$this->form_validation->set_rules('position','Position','required');
$this->form_validation->set_rules('position','Position','numeric');
$this->form_validation->set_rules('name','Name','required');
if ($this->form_validation->run() === FALSE) {
$data['name'] = $data['menu_item']['name'];
$this->load->view('templates/header', $data);
$this->load->view('templates/youarehere', $data);
$this->load->view('templates/menu', $data);
$this->load->view('templates/admin', $data);
$this->load->view('menu/item', $data);
$this->load->view('templates/footer');
}
else {
$this->menu_model->update_menu();
redirect('menu');
}
}
The item view is:
<?php echo validation_errors(); ?>
<?php echo form_open('menu/item'); ?>
<?php echo form_label('ID ', 'id'); ?>
<?php echo form_input('id', $menu_item['id'], 'readonly'); ?><br><br>
<?php echo form_label('Name ', 'name'); ?>
<?php echo form_input('name', $menu_item['name']); ?><br><br>
<?php echo form_label('Position ', 'position'); ?>
<?php echo form_input('position', $menu_item['position']); ?><br><br>
<?php foreach($articole as $articole_item):
$articol1[] = $articole_item['id'] . ' ' . $articole_item['title'];
endforeach; ?>
<?php echo form_label('Associated article ', 'associated_article'); ?>
<?php echo form_dropdown('associated_article', $articol1, $menu_item['articol_asociat']); ?><br><br>
<?php echo form_label('Menu activ ', 'activ'); ?>
<?php echo form_checkbox('activ', '1', TRUE); ?><br><br>
<input type="submit" name="submit" value="Save menu"/>
</form>
In this view I edited menu items. Everything works fine when when everything is right. When I introduce something wrong in a field, like string into "position" field, the form redirect to item view, but with empty fields and with the error message. I want to keep what is entered in field and the error message.
What is wrong with my code?
Change your form :
<?php echo form_label('ID ', 'id'); ?>
<?php echo form_input('id', set_value('id'), 'readonly'); ?><br><br>
<?php echo form_label('Name ', 'name'); ?>
<?php echo form_input('name', set_value('name')); ?><br><br>
<?php echo form_label('Position ', 'position'); ?>
<?php echo form_input('position', set_value('position')); ?>
set_value() replace your old values
Finally i got this done with the likes and statuses but I would like to ask for help if it is possible somehow to transfer also the pictures on web.
thank you
<?php
$facebook_page_id = '**********';
$access_token = '************';
$number_of_posts = 2;
$json_content = file_get_contents('http://graph.facebook.com/'.$facebook_page_id.'/feed?access_token='.$access_token);
$raw_data = json_decode($json_content);
$i=0;
foreach ($raw_data->data as $feed ) {
$feed_id = explode("_", $feed->id);
if (!empty($feed->message)) {
$i++;
if ($i<($number_of_posts+1)) {
?>
<div class=”fb_update”>
<?php if (!empty($feed->likes->count)) { ?>
<div class=”fb_likes”>
<?php echo $feed->likes->count; ?>
</div>
<?php } ?>
<?php if (!empty($feed->created_time)) { ?>
<div class=”fb_date”>
<?php echo date('F j, Y', strtotime($feed->created_time)); ?>
</div>
<?php } ?>
<div class=”fb_message”>
<?php echo $feed->message; ?>
</div>
</div>
<?php } ?>
<?php } ?>
<?php } ?>
Yes, $feed->picture will get you the URL to an image for a particular item, if it exists.
You should really look at using cURL via the PHP SDK for this instead of file_get_contents(). It is more robust.
I would like to show certain data in the HTML/text widget with shortcodes.
I already made the include php call in my functions.php:
function event_widget($atts) {
// turn on output buffering to capture script output
ob_start();
// include file (contents will get saved in output buffer)
include("wp-content/themes/mytheme/widgets/event.php");
// save and return the content that has been output
$content = ob_get_clean();
return $content;
}
//register the Shortcode handler
add_shortcode('event', 'event_widget');
It gets the data to the widget if I put just plain text to event.php, so the call is done correctly, but I don't know how to write the event.php to get this data:
// the loop
<?php if (have_posts()) :
while (have_posts()) : the_post(); ?>
<ul>
<li>
<?php if( get_post_meta($post->ID, "customfield1", true) ): ?>
<?php echo get_post_meta($post->ID, "customfield1", true); ?>
<?php endif; ?>
</li>
<li>
<?php if( get_post_meta($post->ID, "customfield2", true) ): ?>
<?php echo get_post_meta($post->ID, "customfield2", true); ?>
<?php endif; ?>
</li>
</ul>
Try this:
global $post;
echo get_post_meta($post->ID, "customfield1", true);
echo get_post_meta($post->ID, "customfield2", true);
If you echo a value that is false it will amount to '' (nothing) so you don't have to check if they are set.
And also this works perfect:
<?php
global $post;
$args = array('category' => 37, 'post_type' => 'post' );
$postslist = get_posts( $args );
foreach ($postslist as $post) : setup_postdata($post);
?>
<?php if( get_post_meta($post->ID, "customfield1", true) ): ?>
<?php echo get_post_meta($post->ID, "customfield1", true); ?></span>
<?php endif; ?>
Is anything "wrong" with this code?
What is the right way to set a (search) form with Zend Framework 2 in the layout.ptml who is visible on any page of the website?
Thanks in advance.
Nick
It is really simple to set any variables to all layouts in ZF2 by EventManager, just attach the EVENT_RENDER event such as:
class Module
{
public function onBootstrap($e)
{
$app = $e->getParam('application');
$app->getEventManager()->attach(MvcEvent::EVENT_RENDER, array($this, 'setFormToView'), 100);
}
public function setFormToView($event)
{
$form = new MyForm();
$viewModel = $event->getViewModel();
$viewModel->setVariables(array(
'form' => $form,
));
}
}
For view in layout use:
<?php if ($user = $this->identity()): ?>
<?php echo 'Login with user' . $this->escapeHtml($user->nome); ?>
| <?php echo $this->translate('Sair'); ?>
<?php else: ?>
<?php
echo $this->form()->openTag($form);
echo "<h5>Forneça seu login e senha </h5>";
echo $this->formRow($form->get('username'));
echo $this->formRow($form->get('password'));
echo $this->formRow($form->get('rememberme'));
echo $this->formSubmit($form->get('submit'));
echo $this->form()->closeTag();
?>
<?php endif; ?>
Is there any way that i can render ONLY the start <form> tag of a Zend_Form object?
print $this->registerForm->renderForm();
renders <form></form>, and i only need <form>
Edit:
After Asleys possible solution i wrote this for My_Form class
public function renderFormOpen() {
return str_replace('</form>', '', $this->renderForm());
}
public function renderFormClose() {
return '</form>';
}
Still looking for at ZF way of doing thins, even though i don't think there is any - after going through the code in the ZF library.
You could write an custom form-decorator that uses a custom view-helper that only renders the open form tag. But I think this would be overkill.
Just "hardcode" the form-tags and fill the attributes with the data provided by the form-variable in your view.
<!--in your view-template -->
<form action="<?php echo $this->form->getAction() ?>"
enctype="<?php echo $this->form->getEnctype() ?>"
method="<?php echo $this->form->getMethod() ?>"
id="<?php echo $this->form->getId() ?>"
class="<?php echo $this->form->getAttrib('class') ?>" >
<!--in case your products are represented as elements -->
<?php foreach ($this->form->getElements() as $element): ?>
<?php echo $element ?>
<?php endforeach; ?>
<!--in case your products are represented as displayGroups -->
<?php foreach ($this->form->getDisplayGroups() as $displayGroup): ?>
<?php echo $displayGroup ?>
<?php endforeach; ?>
<!--in case your products are represented as subforms -->
<?php foreach ($this->form->getSubforms() as $subform): ?>
<?php echo $subform ?>
<?php endforeach; ?>
<!--in case your products are rendered by a view helper -->
<?php foreach ($this->products as $product): ?>
<?php echo $this->renderProduct($product) ?>
<?php endforeach; ?>
</form>
Just for fun the overkill way
// Get your products form
$form = new Form_Products();
// Add custom prefix path
$form->addPrefixPath('Foobar_Form_Decorator', 'Foobar/Form/Decorator', 'decorator');
// Set OnlyOpenTagForm-ViewHelper for FormDecorator
$form->getDecorator('Form')->setHelper('OnlyOpenTagForm');
// copy Zend/View/Helper/Form to Foobar/Form/Decorato/OnlyOpenTagForm.php
// In OnlyOpenTagForm.php
// replace Zend_View_Helper_Form with Foobar_View_Helper_OnlyOpenTagForm
// replace method "form" with onlyOpenTagForm"
// replace
if (false !== $content) {
$xhtml .= $content
. '</form>';
}
// with:
if (false !== $content) {
$xhtml .= $content;
}
Done! - The Java-Guys will love it ;)
You can render just the open form tag by passing false to the form decorator like so:
<?php echo $this->form->renderForm(false) ?>
Which will output something like:
<form id="post" enctype="multipart/form-data" method="post" action="/post">
Additonally you can pass a string to the form decorator to be enclosed by the form tags like so:
<?php echo $this->form->renderForm('Some Text') ?>
Which outputs something like:
<form id="post" enctype="multipart/form-data" method="post" action="/simchas/post">Some Text</form>
Hope this helps...
You could do something like this:
echo $this->form->getDecorator('Form')->setElement($this->form)->render(false);
