ggenc Posted February 11, 2012 Share Posted February 11, 2012 Hey guys! I'm pretty new to php and starting work on a project, the first part I'm working on is a html page with text fields like this: URL: Dropdown box: Submit when the submit happens I want it to post to a php page, parse whatever is inside a set of <h2> tags and print it to to the php page, also the user selects four options from the dropdown box and I need to print the string contained in the selection to the next page as well, As I said I'm pretty new but here's what i threw together so far based on references I found, but it doesn't work correctly: parse.html: <html> <body> <form action="parse.php" method="post"> URL: <input type="text" name="turl" /> <br> Option: <select name="selectskill"> <option value="1">Low</option> <option value="2">Mid</option> <option value="3">High</option> <option value="4">Known</option> </select> <br> <br> <input type="submit" /> </form> </body> </html> parse.php: <html> <head></head> <body> <?php $lol = $_POST["turl"]; $str = file_get_contents($lol); $DOM = new DOMDocument; $DOM->loadHTML($str); // Grab text inside the heading 2 tags $items = $DOM->getElementsByTagName('h2'); echo "option: " . $lol; // Display the content inside the second set of H2 tags echo $items->item(1)->nodeValue . "<br/>"; ?> </body> </head> </html> Thanks for all the help in advance! Quote Link to comment Share on other sites More sharing options...
scootstah Posted February 11, 2012 Share Posted February 11, 2012 So what isn't working? Any errors? Quote Link to comment Share on other sites More sharing options...
ggenc Posted February 11, 2012 Author Share Posted February 11, 2012 well basically there is a title in the page I'm trying to parse (title of a tournament) and it is between a set of <h2> tags, I was testing it on a test tournament page and the title of the tournament was "Test tourney" now when I input the link to a new tournament it just keeps saying "test tourney", as if it's not parsing the new link. also the option from the drop down box doesn't get printed to the next page too Quote Link to comment Share on other sites More sharing options...
MMDE Posted February 11, 2012 Share Posted February 11, 2012 What you should make sure of is that you actually get the content from the page. I as late as yesterday wasn't able to do that, because the webpage I tried get it from didn't like what I sent of user-agent. You can read about that here: http://davidwalsh.name/set-user-agent-php-curl-spoof So make sure you actually get the content, try to echo it straight away, just for test. $str = file_get_contents($_POST["turl"]); if($str != false){ echo $str; }else{ echo 'Wasn\'t able to get contents from file/url'; } Also this line, are you sure you want the second h2 tag and not the first? echo $items->item(1)->nodeValue . "<br/>"; I'm somewhat sure you want to do this instead: echo $items->item(0)->nodeValue . "<br/>"; Quote Link to comment Share on other sites More sharing options...
ggenc Posted February 11, 2012 Author Share Posted February 11, 2012 I tried what you suggested and it does print the full page when echo'ed so I'm not sure what the problem is, also I do mean to grab the second <h2> because the second occurance of h2 on the page is the title (the first is a heading i don't need) Quote Link to comment Share on other sites More sharing options...

I'm not sure if it should have popped up any warnings or errors by now if there was anything wrong with it, but it doesn't hurt testing... if($DOM->loadHTML($str) == false){ echo 'Wasn\'nt able to parse HTML'; }else{ echo 'Was able to parse HTML'; } And then finally test if it actually was able to parse a second h2 tag: echo $items->length; if($items->item(1)->nodeValue == false){ echo 'Wasn\'t able to find a second h2 tag'; }else if($items->item(1)->nodeValue == ''){ echo 'The content of the second h2 tag was parsed as empty'; }else{ echo $items->item(1)->nodeValue . ', IT WORKED!'; } Quote Link to comment Share on other sites More sharing options...
ggenc Posted February 11, 2012 Author Share Posted February 11, 2012 well I messed around a bit and its actually working! the only problem I have now is I can't figure out how to grab the selection that the user chose from the dropdown box on the previous page and display it as text under the title that is printed (hope that makes sense) Quote Link to comment Share on other sites More sharing options...
