PHP - Urls And $_get

Okay, i know there are lots of these questions out there and tons of ways to do this. I do have it working to replace URLs with <a href="URLs">URLs</a> but now i need some help detecting <a href=""></a> so the preg_replace will not double up the code and mess up the link.

here is my code so far.
Code: [Select]
<?php
echo 'COMMENTS<br /><br />';
  while($rows = mysql_fetch_array($comres)){
  list($comid, $menu_title, $post_id, $comdate, $comname, $comment) = $rows;
  $comment = nl2br($comment);
  $comment = preg_replace('/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/', '<a href="$0" target="_new">$0</a>', $comment);
  $comment = str_replace("&acute;", "'", $comment);
  $comdate = date("g:ia - M j, Y",strtotime("$comdate"));
  echo 'User: '.$comname.'<font color="#B20303"> - '.$comdate.'</font><br />';
  echo '&nbsp;&nbsp; - '.$comment.'<br /><br />';
  }
?>

so with this code, if someone commented a link like this

http://example.com

it will turn it this

<a href="http://example.com" target="_new">http://example.com</a>

but now if someone knew some basic HTML coding, and they used this

<a href="http://example.com">Example.com</a>

it will look like this...

<a href=<a href="http://example.com" target="_new">http://example.com</a>>Example.com</a>

Hello!
First... I'm sorry about my english skills.. Seems that with my own language I don't get a correct or good answer
So.. I have a site where visitors can put there favorite links to other sites and show them to others.

My problem is multiple urls to same locations in sites-table.
example:
 http://google.com
 http://google.com/
 http://www.google.com
 http://www.google.com/
 http://www.google.com/index.php (?)
they all lead to same...

is there any light and powerfull way to check these? I'm trying to use query with "like" but it only works if there is exactly same url. I use fopen to check that url really exicst..

table:
Sites (basic information for link)
 -id
 -url
 -title
 +some meta tags if found
 -timestamp

I'm not asking to do me this code.
But if someone can tell me just what functions and others I'm looking for and what I need for this...

My coal is to keep sites-table as clean as it can be.
If visitor adds a url that is already in sites-table only thing that happens is updating timestamp.

Thank you all for helping me!

I would love to google my question, but I don't know how this is called....

I want to create URLs for each user of a site with this format:

www.mysite.com/user1

Facebook does this, for example. In a static page I'd do it with a folder and index file for each user, but that's not practical if you have too many users. Could you explain how this is done or at least how it is called so I can find myself something to read?

Thanks!!!

Hi,

What is the best way to change:

www.mysite.com/product.php?id=1&sort=2&cat=z

to:

www.mysite.com/1/product-name-here

I would need the other variables in the URL (sort & cat...) to also pass through to the new address. Is this an .htaccess change or via PHP code? Any help appreciated, thanks.

Say my URL is http://www.example.com/catalog.php?category=hats&prodID=53

and I use Mod-rewrite to make it http://www.example.com/catalog/hats/53/

Can I still use $_GET['category'] to get the parameters? If so, how?

Can someone help me to generate SEO friendly URLs?

I dont want my URLs to be presented like:
www.example.com/listprod.php?categ=1&subcateg=7

I want it to dynamically do the following:
www.example.com/listprod/cameras/slr

I am using seo friendly urls so when someone makes a post named "this is a post" the url will point to www.example.com/topic/this_is_a_post

But when the user enters a character in their post name that means something in a url(? /) it obviously breaks. How can i make the urls safe from this without str_replace as i want to keep the characters.

I have a string containing long text, which contains urls in the form of example.com or www.domain.com (simple plain text, not html links). How I can delete all of them. I need a php regex to delete all terms containing ".com"
 

Hi again,
  okay going to be a bit difficult to explain clearly but i will try. For instance i have a script on my categories.php ready to run when called from index.php I land on this page no 1 /categories.php?name=$pagename   from there the user has an option to go this page 2,

/categories.php?name=$pagename&id=$myid      <---   ok my question.. is it best to carry on scripting on categories.php for both pages (urls) or is it best to make another page example categories2.php for page number 2. Currently all my code is on categories.php and it is performing as desired. Still i want to know which is better and how do you guys work, if you have a similar case any suggestions and guidance would be appreciated thanks all.

im sure i am missing something simple. but this is killing me.

i get this to work:
Code: [Select]
$url = (isset($_POST['url'])) ? $_POST['url'] : '';
$BlockedNames = array('nepwk', 'teleworm');
$BlockedDomains = array('nepwk.com', 'teleworm.com', 'yopmail.com', 'adf.ly', 'www.nepwk.com');
@list($name, $domain) = explode("http://", $url);



else if(in_array($name, $BlockedNames) || in_array($domain, $BlockedDomains)) {
$mesaj = "<div class=\"msg\"<div class=\"error\">Your URL has been blocked by our system!</div></div>";
}

now the above works if i type the whole domain for every single url i want to block

but i want to know is how would i add a catch all of sorts to the domain

so say the domain is: http://www.google.com
i want to block everything google so all of the following would be blocked as well
http://www.google.com/whatever
http://www.google.com/anything
http://www.google.com/something

i want all of those to be blocked automatically without having to add each individual one

im trying to block adf.ly links which change for each person and each url they mask and i want to take proactive measure to just block them from being added into my form instead of having them added to my database then having to go and manually delete them.

any questions or if this doesn't make sense let me know.

thanks in advance (and maybe this is bad code im a noob so go easy )

My goal was to create a constant that could be included on the pages, that no matter where it was located in the structure, would be able to find the template files, css, images, etc.  using the following code:

Code: [Select]
if($_SERVER['HTTP_HOST'] == "localhost"){
    define('SITEURL', 'http://' . $_SERVER['HTTP_HOST']);
    define('SITEPATH', $_SERVER['DOCUMENT_ROOT']);
    define('CSS', $_SERVER['DOCUMENT_ROOT'] . '/css/');
    define('IMAGES', $_SERVER['DOCUMENT_ROOT'] . '/images/');
}
else{
    define('SITEURL', 'http://' . $_SERVER['HTTP_HOST']);
    define('SITEPATH', $_SERVER['DOCUMENT_ROOT']);
    define('TEMPLATE', $_SERVER['DOCUMENT_ROOT'] . '/incs/template/');
    define('CSS', $_SERVER['DOCUMENT_ROOT'] . '/css/');
    define('IMAGES', $_SERVER['DOCUMENT_ROOT'] . '/images/');
}

I put the above in a variables.php file that is in the includes folder (named incs) and I call it using the typical include statement.

The problem is that when I use the constant to grab the CSS file, its not working when using:

Code: [Select]
<link rel="stylesheet" href="<?php echo CSS . "template.css" ?>" type="text/css" media="screen" />

I can view the page source and it has the path right, but I cannot figure out how to get it to actually pull in the css file.  I know the echo command is not correct, at least I dont think it is, but have not been able to figure out any other way.

Also, is there a better way to define the constants to the file locations and have it automatically detect whether its on the test server or production and then be able to reference those locations no matter where it is in the structure?

Hi guys,

I'm parsing a bunch of html sources, some of them (a minority) contain base64 encoded URLs. At least 20-30 URLs per page. Some of the information I need is taken from the URLs.

I'm looking for a way to parse these URLs without losing too much time (20-30 URLs per page and I need to parse about 10k pages daily).

Should I regex each source individually for base64 encoded URLs and then decode them each time and isn't that going to take a lot of time/resources (especially considering it's only a minority that have the base64 URLs in them)? Or is there a better way to do it?

Code snippets are absolutely welcome!

Thank you in advance

Hi Everyone,   I am really struggling with this.....Cannot find a solution anywhere.   I have a website with SSL installed.

Hi Everyone,

Before I ask my question I would like to give everyone a background on myself. I'm currently in the learning stages of PHP and MySql.

(I apol. in advance for my lack of tech. terminology)

I have a question regarding how to "make" or "produce" certain pages in php code. In my past I've always manually made a pages. For example, aboutus.html, information.html, cats.html etc ... I think you get the idea.

Assuming code is being used. How would one go about "making" or "producing" pages that are fully functional php pages? Where people can log in, make edits, write reviews etc ... (a few examples are below)

Do the owners/programmers of the below websites manually "make" or "produce" these pages?
http://cars.oodle.com/used-cars/san-jose-ca-area/
http://www.yelp.com/biz/lotus-of-siam-las-vegas
http://restaurants.uptake.com/california/san_jose/509917137.html
http://www.yelp.com/c/san-jose/restaurants

My question is, how can I "make" or "produce" these types of pages for my website? Can anyone offer my any tips/tricks on how to do so. All opinions welcome. Thanks everyone in advance for the help.

I would like to better understand relative and absolute paths when rewriting URLs.  My virtual host configuration is shown below.

I wish the server to see something like:

https://example.com?page=page1&controller=controller1&data1=123&data2=321

Given the rewrites as shown in my virtual host, what would be the proper URL in the browser?  One of these (note the ? and &), or something different?

https://example.com/page1/controller1?data1=123&data2=321
https://example.com/page1/controller1&data1=123&data2=321

Next, if I enter one of the URLs, how do relative paths to images, etc work?  Would the browser think it is in the root directory, or in /page1/controller1?  I had problems with relative paths, and changed to absolute paths, and it fixed the problem, but I wish to better understand what is happening.   On a side note, I would appreciate any critique of my virtual host configuration.  My goal is for all requests to example.com to redirect to https://example.com, for only https://example.com (no subdomain) to redirect to https://www.example.com, and do the rewriting of page and controller.   Thank you

# Note that if a virtual ServerName is not found (i.e. IP 192.168.1.200), Apache defaults to first virtual host.
