Using Preg_match_all To Locate HTML Anchor Link BUT Only If The Link Is A .pdf File
The subject line describes what I'm trying to do, (and after thinking about it for a day or so and trying different things; searching around for similar questions on the board,) but I still haven't found a proper regular expression.
I am trying to use preg_match_all to locate HTML Anchor link BUT only if the link is a .pdf file within text from a database table. It actually was working just fine until I recently made a change regarding new lines () and (<br />) in the text that is to be searched. But after making changes regarding the new lines and things, my previous regexp doesn't work correctly. Here is the regexp I am trying to use:
preg_match_all('/<a href="(.*)">(.*)</a>/U', $entry->Record['e_entry'], $res_output, PREG_PATTERN_ORDER);
That regexp does find each occurance of an <a href="">something here</a> link... but I need it to only find occurances of an anchor link if it is a PDF file link (ex: <a href="../something.pdf">something</a>). So I tried changing the regexp to something like this:
preg_match_all('/<a href="(.*).pdf">(.*)</a>/U', $entry->Record['e_entry'], $res_output, PREG_PATTERN_ORDER);
But in the preg_match_all results array ($res_output) a regular <a href="">something here</a> link is ALSO found as well as the .pdf links... I am trying to only find links that contain .pdf at the end of the file name. Sorry that this is written kind of strangely, if you need more info let me know. Does anyone know what I need to change in the regexp to ONLY find HTML anchor links that contain .pdf at the end of the HREF?

Want To Make A Link Anchor Call A Script
In a certain PHP document at my site, I have a link to a Word version of the same document. If the user downloads it, I want to log that s/he has done this. Data logging isn't the issue. Calling a PHP script is. So what I have is something like: <a href=http://my-web-site.com/documents/mydoc.doc>Click here</a> to download a Word version of this document. Of course the <a> anchor exists only on the client side and the PHP script exists only on the server. But since clicking the anchor sends a message to the server, there ought to be a linkage that can be exploited to enable a PHP call. I just can't think of one.

Dynamic Download Link - Not Direct File Link
I'm posting a podcast feed that makes reference to audio files for download. Instead of linking to the files directly (e.g. www.mywebsite.com/podcast.mp3), I want to link to the file as get variables so that I can track number of listeners (e.g. www.mywebsite.com/?audio=podcast.mp3). Where would I look to get something like this to work? How do I start sending audio data to the user using a link like this?

Search Each Html File For Every Occurrence Of A Link
I am looking to transfer content of hundreds of html files into a database. I need to search each html file for every occurrence of a link, image if there is one present, alt text and anchor text. It should then be placed in several variables $link, $src, $alt, $anchor and placed into a csv file so I can import it into a database. The only thing that I have done so far is read the contents of the html file into a string. <a href="link.htm" target="_blank"><img border="0" src="example.jpg" alt="This is an example"><br>This is an example</a></td> So in this example, I need to retrieve link.htm, example.jpg, 'This is an example', and 'This is an example'.

How Do You Link To An External PHP Script In An HTML File?
I installed XAMPP, so everything should be configured properly. However, I'm still having problems. So, here are some of the questions I have. If anyone could help me out on any of them, that would be great. 1. What is a web server? How is it helping me write PHP? 2. When I open my PHP files in my browser, they are still not read properly. Any known reason why? 3. How do you link to an external PHP script in an HTML file? Is there a such thing, or am I totally clueless?

Find A Link - Link Exchange Script
I am currently writing a link exchange script. Is it possible to have the script detect if the link is/is not present on the page it is supposed to be? I have this: reciprocalcheck.php: <?php $webpage = file_get_contents("http://localhost/ee/admin/reciprocaltest.html"); $find = '<a href="http://www.domain.com/enter.php?refer=1">' //<a href="http://www.domain.com/enter.php?refer=1"> $offset = strpos($webpage,$find); if($offset != 0) { echo "link found"; } else { echo "link NOT found"; } ?> This works but it also works even if the page it is searching only has http:// on. So how can I get it to search for that exact peice of code? ....

HTML Link
The select options include each of the products which are coded by an ID number. To create a link in the outgoing mail by PHP page. I have a var coming from a Select Option $productid. It is written as <OPTION VALUE="23532"> What I need to do is have this provide a complete link and name of the product. I would like to parse the databse of the store so that if the ID number is provided, on the resulting php page that sends the mail and displays the results on the screen, I want to read from the data base to complete the link that goes on to the screen and into the mail Thus pulling $product_name $product_description $product_thumbnail and composing it into a preformatted HTML email message. <P ALIGN="CENTER"><IMG SRC="$imagelink" width="100" height="120"><BR> <A HREF="http://www.foobar.com/products.php?productid="$productid"> $product name</A> $product_description</P>

Html Link To Data
The site I am building needs several html links, from images, to variouse categories. There are two foreign keys in the table so there is no need for a join. I simply wish to search those fields and gather all the relevant numbers to display on the results page. The method is a link with the correct variable. The query: <?php require_once('Connections/sports_connect.php'); ?> <?php mysql_select_db($database_sports_connect, $sports_connect); $query_qLinks = "SELECT department_id, cat_id, advert FROM entry"; $qLinks = mysql_query($query_qLinks, $sports_connect) or die(mysql_error()); $row_qLinks = mysql_fetch_assoc($qLinks); $totalRows_qLinks = mysql_num_rows($qLinks); ?> I am trying to get a "detail" link modified to send to the results page to where the data will be recieved. search_result.php?department_send=<?php echo $row_qLinks['department_id']; ?>

Grabbing A Link Out Of A Line Of HTML
I currently have a huge function that will crawl a page of a site and grab all the links off the page. There seems to be a problem though by grabbing the link text. I was curious how I can improve my function. So I was curious if anyone knows how I can make a function that will grab "info@test.com" out of this line: Just some text. <a href="mailto:info@test.com">Contact Us.</a>. The main problem I come up with is sometimes it will grab the "Contact Us" or it screws up when they have additional values in the <a href> tag.

So my questions: 1. is there any other method? 2. could any of you maybe specify a bit more details about this function and how to use it.

Regalar Expression To Extract An Html Link From A Page
I have a regalar expression to extract an html link from a page: href=(["']?)([^>1]*.html)1(?: [^>]*)?> It looks after the "href" for an optional quote and then looks for something that is not the quote or the endarrow. The problematic part is [^>1]*. It should exclude anything with the quote, but somehow that doesn't work. Maybe 1 is not allowed inside brackets? I would like some advice on how to handle this.

File With No Link
I have a link on my web page. When clicked, opens up a pdf file that is stored on my server. Every file is specific to a user's user name and I don't want users to see each other's files. For example: When User1 clicks on the link, it opens up http://mydomain.com/files/user1.pdf and when User2 clicks on the link, it opens up http://mydomain.com/files/user2.pdf. So, if User1 knows about User2, he can see User2's pdf file. How can I make the file open up in a different window without the file path in the address bar?

Creating Link To File Or Temp File For User Download
I am designing a document management system (DMS). The files are stored in a directory on the webserver. The filenames for the documents are stored in a MySQL database. The DMS will track revisions from the initial version through the updates. We must have strict permissions set so only authorized personnel can access some documents. All of the documents when uploaded are given totally random names such as "114723fb5422c6bd5ed18f6.doc". Is there a way, without the webserver creating a new file name "document_specs_ver2.doc" to have the file download named "document_specs_ver2.doc". If I must physically create a new file, how do I know when the webserver would be allowed to delete it? Notes: The files will be in several different file formats, not just "doc".

How To Add A Download Link For A PDF File?
I'm wondering if someone might be willing to walk me through this? I see in my database where all my files are stored in a directory called www. Now, if I were to add a new page to my site would I need to go into that www directory and click Upload File, Add Directory or Add File? I have a page where it has a WYSIWYG editor. What I'm wanting to do is duplicate that page with the editor on it, rename it and also add a link to point to it. But I'm not sure how to do that. One other thing I want to do with this page is be able to put a PDF file on there with a button people can download it. That comes to my second dilema, I guess I would need to add somewhere in my CMS (admin) area where I can upload the PDF file so it will show up on the site. Any idea's for me?? Remember I'm a complete newbie. Have no idea how to write code/scripts, but do think I could copy/paste *grin* if someone walked me through it.

Downloading File Via Curl When Url Not A Direct Link?
I am trying to use CURL to log into a site, download a file, and send the results. So far I have gotten it to log-in and send results (based on sample data), but I cannot get the file to download. For example, the url is in a format similar to the link below When you click it, it redirects somewhere and provides REPORTS.ZIP (note the bolded area of the example link). http://www.example.com/file.php?date=2006/01/18&date2=2006/01/19&file=REPORTS&info=all The problem is that the url is not a direct link and when clicked, it prompts any (standard) browser to download the (zip) file. When I tried using wget, it downloads file.php which does no good. What do I need to do for it to download and write the file to my local directory?

PHP-generated Link To Local File Doesn't Work When Clicked On. Why?
I'm running an Apache server on my own computer (Windows XP Pro). I wrote a simple PHP script (called test3.php) that I'm running by putting the following URL in the address bar of the browser (Firefox) .... http://localhost/test3.php The script generates the following link using the echo statement ... <a href="file:///C:/pictures/xyz.jpg"> Picture </a> ("C:/pictures/xyz.jpg", as you can guess by now, is an image file on my harddrive, but it's not in the document root). When I clicked on the link, nothing happened. However, if I RIGHT-click on it and select "Copy link location" (which copies the URL to the clipboard) and then paste the URL into the address bar of the browser, the picture then displays correctly. Why did it not work when I clicked on the link the first time, but it only worked when I pasted the link to the address bar? Is there some special notation/syntax that I need to use to get this to work properly?
