For some reason I have to write HTML::macro() to return HTML tags.
HTML::macro('myMycro', function()
{
$result = '<form id="xxx">...';
return = $result;
}
then I can use the HTML::myMacro() inside my blade.
{{ HTML::myMacro() }}
Is it possible to use form helper Form::open(), Form::input() to generate HTML tags inside the macro so I don't have to manually write tags???
If so, please suggest me how to do it because of my poor background in PHP and Laravel, I just simply tried
...
$result = Form::open('some_parameters');
...
But I didn't work, I don't know can I use form helper outside blade or not, so please advise me.
Thanks.
I dont see any reason why not.
This works like a charm
Form::macro('myForm', function()
{
$output = Form::open(['url/to/post']);
$output .= Form::text('firstName');
$output .= Form::close();
return $output;
});
// Then use in in regular PHP view...
echo Form::myForm();
// ... or even Blade view
{{ Form::myForm() }}

I'm placing a search form of 6 fields on my home page which includes a text box field named course. I want to show course suggestions while user typing. One more is, I want to show/hide some fields according to the option of first field dropdown. Any help would be appreciated.
You can use jQuery Auto Suggest which is included with WordPress : wp_enqueue_script
With this you can write a form that does a Ajax lookup to the the Ajax URL handler. Which you can add_action onto. AJAX in Plugins
So you can ajax lookup and then on the action side you can just perform a get_posts to match titles, or a raw sql Query. And return what is needed. edit your functions.php.
add_action('wp_enqueue_scripts', 'se_wp_enqueue_scripts');
function se_wp_enqueue_scripts() {
wp_enqueue_script('suggest');
}
add_action('wp_head', 'se_wp_head');
function se_wp_head() {
?>
<script type="text/javascript">
var se_ajax_url = '<?php echo admin_url('admin-ajax.php'); ?>';
jQuery(document).ready(function() {
jQuery('#se_search_element_id').suggest(se_ajax_url + '?action=se_lookup');
});
</script>
<?php
}
add_action('wp_ajax_se_lookup', 'se_lookup');
add_action('wp_ajax_nopriv_se_lookup', 'se_lookup');
function se_lookup() {
global $wpdb;
$search = like_escape($_REQUEST['q']);
$query = 'SELECT ID,post_title FROM ' . $wpdb->posts . '
WHERE post_title LIKE \'' . $search . '%\'
AND post_type = \'post_type_name\'
AND post_status = \'publish\'
ORDER BY post_title ASC';
foreach ($wpdb->get_results($query) as $row) {
$post_title = $row->post_title;
$id = $row->ID;
$meta = get_post_meta($id, 'YOUR_METANAME', TRUE);
echo $post_title . ' (' . $meta . ')' . "\n";
}
die();
}
Use ajax for both. You may have to write some mysql query to retrieve the required fields(post titles or whatever it is) from the table.
I have a simple Joomla controller, but I can't redirect anything.
According to the documentation:
class MyController extends MyBaseController {
function import() {
$link = JRoute::_('index.php?option=com_foo&ctrl=bar');
$this->setRedirect($link);
}
}
//The url contains & html escaped character instead of "&"
This should work, but I get a malformed URL. Is there something I'm missing here? Why is Joomla converting all the "&" characters into &'s? How am I suppose to use setRedirect?
Thank you
Alright, I fixed it. So if anyone needs it:
instead of
$link = JRoute::_('index.php?option=com_foo&ctrl=bar');
$this->setRedirect($link);
use
$link = JRoute::_('index.php?option=com_foo&ctrl=bar',false);
$this->setRedirect($link);
to make it work.
Glad you found your answer, and by the way, the boolean parameter in JRoute::_() is by default true, and useful for xml compliance. What it does is that inside the static method, it uses the htmlspecialchars php function like this: $url = htmlspecialchars($url) to replace the & for xml.
Try this.
$mainframe = &JFactory::getApplication();
$mainframe->redirect(JURI::root()."index.php?option=com_foo&ctrl=bar","your custom message[optional]","message type[optional- warning,error,information etc]");
After inspecting the Joomla source you can quickly see why this is happening:
if (headers_sent())
{
echo "<script>document.location.href='" . htmlspecialchars($url) . "';</script>\n";
}
else
{
... ... ...
The problem is that your page has probably already output some data (via echo or some other means).
In this situation, Joomla is programmed to use a simple javascript redirect. However, in this javascript redirect it has htmlspecialchars() applied to the URL.
A simple solution is to just not use Joomlas function and directly write the javascript in a way that makes more sense:
echo "<script>document.location.href='" . $url . "';</script>\n";
This works for me :)
/libraries/joomla/application/application.php
Find line 400
// If the headers have been sent, then we cannot send an additional location header
// so we will output a javascript redirect statement.
if (headers_sent())
{
echo "<script>document.location.href='" . htmlspecialchars($url) . "';</script>\n";
}
replace to
// If the headers have been sent, then we cannot send an additional location header
// so we will output a javascript redirect statement.
if (headers_sent())
{
echo "<script>document.location.href='" . $url . "';</script>\n";
}
This works!
I've posted an edit to my question. While working on it I noticed the problem is easy to simplify.
I need a custom format of my submenu so i have to use partial. But then the problem occurs.
The below code shows the INCORRECT level (0):
echo $this->navigation()->menu()
->setMinDepth(1)
->setMaxDepth(1)
->setRenderParents(false)
->setOnlyActiveBranch(true)
->renderPartial(null, array('partials/menu.phtml', 'default'));
The below code shows the CORRECT menu level (1)
echo $this->navigation()->menu()
->setMinDepth(1)
->setMaxDepth(1)
->setRenderParents(false)
->setOnlyActiveBranch(true)
->render();
Any ideas? Guys please. I would appreciate any help!
Edit
My partials/menu.phtml:
foreach ($this->container as $page)
{
$active = $page->isActive();
echo '<div class="item">';
echo '<a class="'. ($active ? 'active' : '') .'" href="' . $this->baseUrl($page->getHref()) . '">' . $page->getLabel() . '</a>';
echo '</div>';
}
EDIT 2
My understanding of Zend_Navigation was, first to prepare container and than put it through partial.
$nav = $this->navigation()->menu()->setOnlyActiveBranch(true)->getContainer();
echo $this->navigation()->menu()->renderPartial($nav, array('/partials/menu.phtml', 'default'));
What is the point of setting set{Min/Max}Depth, parentRendering at the container when passing it anywehere is useless?
I use this code:
<?=$this->navigation()->menu()->renderPartial(null, 'shared/menu.phtml')?>
you should pass true to the method $page->isActive(true) so that also functions in depth.
in your partial
foreach ($this->container as $page) {
$active = $page->isActive(true);
if (count($page->getPages())) {
foreach ($page->getPages() as $subPage) {
$active = $subPage->isActive(true);
echo '<div class="item">';
echo '<a class="'. ($active ? 'active' : '') .'" href="' . $this->baseUrl($subPage->getHref()) . '">' . $subPage->getLabel() . '</a>';
echo '</div>';
}
}
}
before the second foreach you could add a check if and when to show the submenu.
my 2 cent.
EDIT
try this:
$partial = array('partials/menu.phtml', 'default');
echo $this->navigation()->menu()
->setMinDepth(1)
->setMaxDepth(1)
->setRenderParents(false)
->setOnlyActiveBranch(true)
->setPartial($partial)
->render();
Came across this while searching for an answer to the same problem. Having looked through the code for Zend_View_Helper_Navigation_Menu, it doesn't look like any of the view helper options are passed through to the view partial, although I don't see why they couldn't be... (in ZF 1.12 take look a line 736 of Zend_View_Helper_Navigation_Menu, the only thing passed is the container itself, the options array could easily be passed along with it, or the container prefiltered, may be worth filing a feature request with ZF)
These options are purely a way of filtering the Zend_Navigation_Container for rendering with the default renderMenu method. As you say, it seems you can accomplish the same thing by first filtering the container and then passing it as the first argument of the renderPartial method
In your main view
Find the container of the submenu located in navigation config. Then echo this container using said partial.
$pages = $this->navigation()->findOneBy('label', 'Label of your submenu');
echo $this->navigation()->menu()->renderPartial($pages,module/partials/menu.phtml');
In the partial (module/partials/menu.phtml)
Customise. This example iterates over the top level pages of your chosen container.
foreach ($this->container as $page) {
echo $this->navigation()->menu()->htmlify($page) . PHP_EOL;
}
I'm an old-newbie in Perl, and Im trying to create a subroutine in perl using HTML::TokeParser and URI.
I need to extract ALL valid links enclosed within on div called "zone-extract"
This is my code:
#More perl above here... use strict and other subs
use HTML::TokeParser;
use URI;
sub extract_links_from_response {
my $response = $_[0];
my $base = URI->new( $response->base )->canonical;
# "canonical" returns it in the one "official" tidy form
my $stream = HTML::TokeParser->new( $response->content_ref );
my $page_url = URI->new( $response->request->uri );
print "Extracting links from: $page_url\n";
my($tag, $link_url);
while ( my $div = $stream->get_tag('div') ) {
my $id = $div->get_attr('id');
next unless defined($id) and $id eq 'zone-extract';
while( $tag = $stream->get_tag('a') ) {
next unless defined($link_url = $tag->[1]{'href'});
next if $link_url =~ m/\s/; # If it's got whitespace, it's a bad URL.
next unless length $link_url; # sanity check!
$link_url = URI->new_abs($link_url, $base)->canonical;
next unless $link_url->scheme eq 'http'; # sanity
$link_url->fragment(undef); # chop off any "#foo" part
print $link_url unless $link_url->eq($page_url); # Don't note links to itself!
}
}
return;
}
As you can see, I have 2 loops, first using get_tag 'div' and then look for id = 'zone-extract'. The second loop looks inside this div and retrieve all links (or that was my intention)...
The inner loop works, it extracts all links correctly working standalone, but I think there is some issues inside the first loop, looking for my desired div 'zone-extract'... Im using this post as a reference: How can I find the contents of a div using Perl's HTML modules, if I know a tag inside of it?
But all I have by the moment is this error:
Can't call method "get_attr" on unblessed reference
Some ideas? Help!
My HTML (Note URL_TO_EXTRACT_1 & 2):
<more html above here>
<div class="span-48 last">
<div class="span-37">
<div id="zone-extract" class="...">
<h2 class="genres"><img alt="extracting" class="png"></h2>
<li><a title="Extr 2" href="**URL_TO_EXTRACT_1**">2</a></li>
<li><a title="Con 1" class="sel" href="**URL_TO_EXTRACT_2**">1</a></li>
<li class="first">Pàg</li>
</div>
</div>
</div>
<more stuff from here>
I find that TokeParser is a very crude tool requiring too much code, its fault is that only supports the procedural style of programming.
A better alternatives which require less code due to declarative programming is Web::Query:
use Web::Query 'wq';
my $results = wq($response)->find('div#zone-extract a')->map(sub {
my (undef, $elem_a) = #_;
my $link_url = $elem_a->attr('href');
return unless $link_url && $link_url !~ m/\s/ && …
# Further checks like in the question go here.
return [$link_url => $elem_a->text];
});
Code is untested because there is no example HTML in the question.
OK. I finally got my zend form working, validating, filtering and sending the contents to my process page (by using $form->populate($formData);)
Now, how do I email myself the contents of a form when submitted? Is this a part of Zend_form or some other area I need to be looking in?
Thanks!
You can use Zend Mail for this, Zend form does not offer such functions.. but its an nice idea.
In your controleller, after $form->isValid();
if ($form->isValid($_POST)) {
$mail = new Zend_Mail();
$values = $form->getValues();
$mailText = 'My form valueS: ';
foreach ($values as $v) {
$mailText .= 'Value ' . $v . PHP_EOL;
}
$mail->setFrom('user#user.de', 'user');
$mail->AddTo('Me#me.de', 'me');
$mail->setSubject->$form->getName();
$mail->send();
} else {
// what ever
}
