I have set two rules :
$route['followers/(:num)'] = 'hall/filter/subscribers/$1';
And :
$route['see/(:num)'] = 'hall/see/$1';
But while the first one is working all fine, the second one behaves juste like the 2nd argument (the :num) wasn't passed at all (displaying see/4 gives the hall/see/ page, not hall/see/4 !). This is very odd because from my point of view, those 2 routes work the same way !!
Any idea ?
Edit :
If I change $route['see/(:num)'] to $route['foo/see/(:num)'] then it works. This is crazy oO
You should use "" instead '', so it should be
$route['followers/(:num)'] = "hall/filter/subscribers/$1";
$route['see/(:num)'] = "hall/see/$1";

I'm using this http://www.xpathtester.com/xpath/5a30592045b6aa5089faf909261ede0b XPath tester, which returns exactly what I want. For some reason it removes my full query, but if you use it, it works.
*/h3[contains(string(), "Description")]/following-sibling::p[1]
But in real life, I get nothing from my variable.
I'm trying to get the data after <h3>Description</h3>, in this case a paragraph <p>.
HTML
$feed_item=
<div class="outer-feed"><ul>
<li><strong>Severity:</strong> <span class="label label-info">Low</span></li>
</ul>
<h3>Description</h3>
<p>The lack of validation of configuration parameters used in SQL queries caused various SQL injection vectors.</p>
...
Here's my XPath
$description_node = $xpath->query('*/h3[contains(string(), "Description")]/following-sibling::p[1]', $feed_item);
$description = "description: " . $description_node->item(0)->textContent;
and var_dump
object(DOMNodeList)#1654 (1) { ["length"]=> int(0) }
And the error
Notice
: Trying to get property 'textContent' of non-object in
What confuses me is that I can get Severity from the same HTML by using this:
$severity_node = $xpath->query('*/li[contains(string(), "Severity:")]', $feed_item);
$severity = preg_replace('/Severity:\W*/u', '', $severity_node->item(0)->textContent);
My first thought was to scale back to just the H3 and output that.
$description_node = $xpath->query('*/h3[contains(string(), "Description")]', $feed_item);
object(DOMNodeList)#1654 (1) { ["length"]=> int(0) } // doesn't contain anything
Given that the following are identical but the first works and the second doesn't, what could be the problem?
$severity_node = $xpath->query('*/li[contains(string(), "Severity:")]', $feed_item);
$description_node = $xpath->query('*/h3[contains(string(), "Description")]', $feed_item);
Why is one working and not the other. And what is the best way to troubleshoot things like this. It seems to work on the xpathtester. What could I be doing wrong that causes this problem in PHP?
Try with this XPath:
//h3[text()="Description"]/following::p[1]
A query starting */h3[...] will only work if the context item when it is invoked is the grandparent of the h3 element. You've given no information about the context item, so I suspect it is something different.
You ask the question(s): "Why is one working and not the other. And what is the best way to troubleshoot things like this. It seems to work on the xpathtester. What could I be doing wrong that causes this problem in PHP?"
Well, the first thing is to understand that XPath expressions may depend on the context item, and that the same expression evaluated with different context items is going to give different results. Once you understand that concept, it hopefully becomes a lot clearer.
If I want to construct this url: /categories/5/update/?hidden=1 how could I pass both {id} param and hidden param (as GET) ?
My route is:
Route::get('categories/{id}/update', 'CategoryController#update');
I don't want to make a form and put it as POST because I have a number of buttons which simply hides/shows/removes a category and dont want to make a lot of forms for simple actions, although it has nothing to do with the question
I'm just a little bit confused, because it seems like action('CategoryController#update', [$id, 'hidden' => 1]) constructs the right URL but I got no idea how it's distinguished that the first one ($id) must be in URL and the second is a GET param
You may also try this to generate the URL:
$action = action('CategoryController#update', [id => $id]) . '?hidden=1';
Also, query string could be passed with any route even without mentioning about that in Route declaration.
I searched the whole day for any solution but did not found any.
I have the same problem as this guy here: Codeigniter Pagination having page number in the middle of url but the "uri_segment" param doesn't work.
My Urls look like:
localhost/controller/0/some/filter/here/
The Pagination returns teh correct link for the next and 2. page.
But once I go there, I get a wrong link back to the first site.
I did something like this:
/*Paginartion Config*/
$pagconfig['base_url'] = base_url($this->uri->segment(1).'/0/'.$this->uri->segment(3).'/'.$this->uri->segment(4).'/'.$this->uri->segment(5).'/'.$this->uri->segment(6).'/'.$this->uri->segment(7).'/'.$this->uri->segment(8));
$pagconfig['total_rows'] = $ress->num_rows;
$pagconfig['per_page'] = 10;
$pagconfig['uri_segment'] = 2;
$pagconfig['prefix'] = '/'.$this->uri->segment(1).'/';
$pagconfig['suffix'] = '/'.$this->uri->segment(3).'/'.$this->uri->segment(4).'/'.$this->uri->segment(5).'/'.$this->uri->segment(6).'/'.$this->uri->segment(7).'/'.$this->uri->segment(8);
Also I just tried using the current_url() as base_url config param and of course I also just tried to use uri_segment = 2 without using pre- and sufix.
It never worked properly.
Routes look like this:
$route['map/(:num)/(:any)'] = 'map/index/$1/$2';
$route['map/(:num)/(:any)/(:any)'] = 'map/index/$1/$2/$3';
$route['map/(:num)/(:any)/(:any)/(:any)'] = 'map/index/$1/$2/$3/$4';
$route['karte/(:num)/(:any)'] = 'map/index/$1/$2';
$route['karte/(:num)/(:any)/(:any)'] = 'map/index/$1/$2/$3';
$route['karte/(:num)/(:any)/(:any)/(:any)'] = 'map/index/$1/$2/$3/$4';
As you can see I use two kind of routes, translates for google.
The routes and Controller also work!
If I type in by hand I get the correct paginated site content:
For Example: localhost/controller/10/some/filter/here returns every row beginning with 11 (it skips first 10 as it should).
Very important is that the number always appears even on the first page where it is 0 - as you can see above.
It would be so great to get any help in that one...
Best Regards
i have an URL: mydomain.com/view/page/about
then i want change it to be: mydomain.com/page/about
i’ve tried add a new routes:
$route[‘page/(:any)’] = ‘view/page/$1’;
but when i refresh my browser, it always show the page in: mydomain.com/view/page/index
any advice to solve my problem?
thank you before
Note that mydomain.com/page won't get you to view/page. Your regexp expects there to be a ending / in the url.
Either do a
$route[‘page/?(:any)’] = ‘view/page/$1’;
Or
$route[‘page’] = ‘view/page’;
$route[‘page/(:any)’] = ‘view/page/$1’;
If you wish to be more accurate.
I am trying to do this route trick:
$route['cp/roles/:num'] = "cp/roles/index/:num";
but it doesn't work :(
please help me!!
advanced thanks .
According to the documentation on URI Routing:
$route['product/(:num)'] = "catalog/product_lookup_by_id/$1";
“A URL with "product" as the first segment, and a number in the second will be remapped to the "catalog" class and the "product_lookup_by_id" method passing in the match as a variable to the function.”
So, for your particular instance, you would do the following:
$route['cp/roles/(:num)'] = "cp/roles/index/$1";
You could try
$route['cp/roles/:num'] = "cp/roles";
and then instead of passing a variable in your function you use
$this->uri->segment(3);
or the number that correspond to the segment.
