I'm trying to append my variable that displays the count after my links, but I already have code I need replacing links to redirect them to a redirect page.
This is my code currently:
$this->post['message'] = str_replace('href="', 'href="./out.php?link=', $this->post['message']);
$this->post['signature'] = str_replace('href="', 'href="./out.php?link=', $this->post['signature']);
So all the links get redirected to out.php
(small additional question how can i make this not effect img href's?)
So back on topic, what I'm trying to do is add $someVariable[value] after my links, also not effecting images.
The variable would show plain text (numbers)
and for example the end result would look like:
Google(##)
where ## represents $someVariable
DOM confuses me, and I cant think of any other way to do it, so I need some help.

$ur = "./out.php";
$k = str_shuffle("7dfg9bf09cv04e79507e197a1dtdy8j3");
$web = $ur."/?link=".$k;
echo $web;
Here is an example.

Escaping quotation marks in PHP
<?php
$ur = "./out.php";
// $k = $this->post['message'];
$k = "hello";
$web = "/?link=".$k;
$li = "".$k."(".$k.")";
echo $li."\n";
?>

I am making a price crawler for a project but am running into a bit of an issue. I am using the below code to extract values from an html page:
$content = file_get_contents($_POST['url']);
$resultsArray = array();
$sqlresult = array();
$priceElement = explode( '<div>value I want to extract</div>' , $content );
Now when I use this to get certain elements I only get back
Finance: {{value * value2}}
I want to get the actual value that would be displayed on the screen e.g
Finance: 7.96
The other php methods I have tried are:
curl
file_get_html(using simple_html_dom library)
None of these work either :( Any ideas what I can do?
You just set the <div>value I want to extract</div> as a delimiter, which means PHP looks for it to separate your string to array whenever this occurs.
In the following code we use , character as a delimiter:
<?php
$string = "apple,banana,lemon";
$array = explode(',', $string);
echo $array[1];
?>
The output should be this:
banana
In your example you set the value you want to extract as a delimiter. That's why this happens to you. You'll need to set a delimiter between your string you want to obtain and other string you won't need at the moment.
For example:
<?php
$string = "iDontNeedThis-dontExtractNow-value I want to extract-dontNeedEither";
$priceElement = explode('-', $string);
echo "<div>".$priceElement[2]."</div>";
?>
The code should output this to your HTML page:
<div>value I want to extract</div>
And it will appear on your page like this:
value I want to extract
If you don't need to save the whole array in a variable, you can save the one index of it to variable instead:
$priceElement = explode('-', $string)[2];
echo $priceElement;
This will save only value I want to extract so you won't have to deal with arrays later on.
I'm not sure what the terminology is, but basically I have a site that uses the "tag-it" system, currently you can click on the tags and it takes the user to
topics.php?tags=example
My question is what sort of scripting or coding would be required to be able to add additional links?
topics.php?tags=example&tags=example2
or
topics.php?tags=example+example2
Here is the code in how my site is linked to tags.
header("Location: topics.php?tags={$t}");
or
<?php echo strtolower($fetch_name->tags);?>
Thanks for any hints or tips.
You cannot really pass tags two times as a GET parameter although you can pass it as an array
topics.php?tags[]=example&tags[]=example2
Assuming this is what you want try
$string = "topics.php?";
foreach($tags as $t)
{
$string .= "tag[]=$t&";
}
$string = substr($string, 0, -1);
We iterate through the array concatenating value to our $string. The last line removes an extra & symbol that will appear after the last iteration
There is also another option that looks a bit more dirty but might be better depending on your needs
$string = "topics.php?tag[]=" . implode($tags, "&tag[]=");
Note Just make sure the tags array is not empty
topics.php?tags=example&tags=example2
will break in the back end;
you have to assign the data to one variable:
topics.php?tags=example+example2
looks good you can access it in the back end explode it by the + sign:
//toplics.php
<?php
...
$tags = urlencode($_GET['tags']);
$tags_arr = explode('+', $tags); // array of all tags
$current_tags = ""; //make this accessible in the view;
if($tags){
$current_tags = $tags ."+";
}
//show your data
?>
Edit:
you can create the fron-end tags:
<a href="topics.php?tags=<?php echo $current_tags ;?>horror">
horror
</a>
I'm working an a shopping cart with a page called display.php. This page is called repeatedly as you go through the navigation, always calling itself but querying for new, more specific things. I am trying to make breadcrumbs that will provide links to previous pages, but it's proving to be tricky.
This part of display.php retrieves "id", which the query uses to find things, and breadcrumbs, which is the previous breadcrumbs string. "id" is always added to the breadcrumbs string.
$id = $_GET['id'];
$breadcrumbs=$_GET['breadcrumbs'];
$breadcrumbs = $breadcrumbs." > ".$id;
echo $breadcrumbs
As the id variable is used to query for things, links are generated to go to display.php all over again but to query for something new and take the breadcrumbs string with it.
<img src="imagen/logo1.jpg" alt="" width="100" height="100" /><br>'. $name . '
Each time I go to a new page, the breadcrumbs display visibly, but how can I safely change these string statements into links? an can't carry another string inside it safely. I think it's possible if I explode the breadcrumb string with the > character as the delimiter. How can I fix this up so it will display nice links in the breadcrumb string?
$breadlist = explode(" > ", $breadcrumbs);
$linkarray = array();
foreach $breadlist as $breadlink
{
$linkarray($j) = "<a href=display.php?id=".$breadlink($j)."?breadcrumbs=".$breadcrumbs.">".$breadlist($j)."";
};
Two apparent problems (among some other small fixes):
You need to urlencode() your URLs.
You need to access arrays with [], not ().
Here is an example to get you started:
$breadlist = explode(" > ", $breadcrumbs);
$linkarray = array();
foreach( $breadlist as $breadlink)
{
$url = 'display.php?id=' . $breadlink . '&breadcrumbs='.$breadcrumbs;
$linkarray[] = '' . $breadlink . '';
}
I have a problem, I'm trying to get some data for a unique link to my site.
When people are viewing eg: video.php?id=23 i want the script to get the data for that site using $_GET['id'].
Here's my script, and I've tried everything. Hope you can help me!
<?php
$vidurl = $_GET['id'];
function fb_count() {
global $fbcount;
$facebook = file_get_contents('http://api.facebook.com/restserver.php?method=links.getStats&urls=http://www.fniis.dk/video.php?id=$vidurl');
$fbbegin = '<share_count>'; $fbend = '</share_count>';
$fbpage = $facebook;
$fbparts = explode($fbbegin,$fbpage);
$fbpage = $fbparts[1];
$fbparts = explode($fbend,$fbpage);
$fbcount = $fbparts[0];
if($fbcount == '') { $fbcount = '0'; }
}
fb_count();
?>
The problem is that it wont let me print the $vidurl, it doesnt seem to work, because it is only getting data from the following link : fniis.dk/video.php?id= and not eg: fniis.dk/video.php?id=123
You have a couple of problems in your code.
First, you won't be able to access $vidurl in fb_count() unless you specify it as global inside fb_count():
global $vidurl;
It is recommended that you pass $vidurl as a parameter fb_count() instead of using global.
Second, your concatenation of $vidurl in file_get_contents is incorrect. You should be using double quotes instead of single quotes so $vidurl will be processed by PHP. It also wouldn't hurt to use urlencode() here:
// note: using single quotes here and just concatenating with "."
$facebook = file_get_contents('http://api.facebook.com/restserver.php?method=links.getStats&urls=http://www.fniis.dk/video.php?id=' . urlencode($vidurl));
That should get your code working.
Im trying to strip find_loc= and &cflt=pizza I got the majority stripped its just these last 2 things and whenever I try to use trim it doesn't delete it out it keeps saying array even when i try to print it, it says array.
<?php
$foo = 'http://www.yelp.com/search?find_loc=2190+W+Washington+Blvd%2C+Los+Angeles+90018&cflt=pizza ';
$blah = parse_url($foo);
$blah[query];
//the code above echos out find_loc=2190+W+Washington+Blvd%2C+Los+Angeles+90018&cflt=pizza
$thids = trim(''.$blah.'','find_loc=');
echo $thids;
?>
$thids = str_replace(array('&cflt=pizza','find_loc='), '', $blah);
parse_str($blah['query'], $query_vars); // decompose query string into components
unset($query_vars['find_loc']); // delete this particular query variable/value
unset($query_vars['cflt']);
$blah['query'] = http_build_query($query_vars); // rebuild the query string
$foo = http_build_url($blah); // rebuild the url
