hello,

i was going through a tutorial on how to display xml data on a website. here is my xml output from my music player:

  <?xml version="1.0" encoding="UTF-8" ?> 
- <hmm status="ok">
- <tracks>
- <track>
  <album>Sixteen Stone</album> 
  <bpm>0</bpm> 
  <database-id>4</database-id> 
  <exists>false</exists> 
  <filename>D:\Temp\Music\h07 - Machinehead.mp3</filename> 
  <index>0</index> 
  <length>256</length> 
  <mood /> 
  <popularity>0</popularity> 
  <recording-year>1994</recording-year> 
  <release-year>1994</release-year> 
  <situation /> 
  <publisher /> 
  <format>MPEG Audio 128 kbps</format> 
  <is-subtrack>false</is-subtrack> 
  <is-favourite>false</is-favourite> 
  <release-type>0</release-type> 
  <subtrack-index>-1</subtrack-index> 
  <artist>Bush</artist> 
  <genre>Rock</genre> 
  <rating>0</rating> 
  <title>Machinehead</title> 
  </track>
  </tracks>
  </hmm>

here is the code that i thought would display the artists name:

<xml ID="music" src="http://localhost:8181/1.0/?method=player.getNowPlayingData"></xml>		
Artist:
<span datasrc="music" datafld="artist"></span>

should this work?

hi all,

quick question... if i have 5 pictures pic1.jpg, pic2.jpg, pic3.jpg, pic4.jpg and pic5.jpg and im viewing pic3.jpg, is there an easy way to make a left and right button to scroll through the pictures by adding or extracting a number?

thx.

echo "</table>";

June 1, 2010

sorry for the newbie questions, i try to figure things out for about 2 hours before i ask questions.

right now im having a problem getting my data into a table. i can get it to show on the screen. here is the code.

	$url1 = "http://sports.espn.go.com/espn/rss/mlb/news";
echo RSS_Display($url1, 8, false, true);

thanks for the help!

June 1, 2010

i tried this, but i must me doing it wrong or in wront place...

if ( $sport == 'URL' && preg_match("/s_url\d+/", $value) ) {        $results[<a href="$sport"></a>][] = $foo[2][$key];       }

May 31, 2010

can i do that when its constantly changing?

May 31, 2010

hi all,

i cannot seem to figure out how to make the url active when i parse it from a string. any ideas?

<?php   
//this array contains sports and their URLs 
$sports = array( 
"NHL" => "http://sports.espn.go.com/nhl/bottomline/scores",
"URL" => "http://sports.espn.go.com/nhl/bottomline/scores"); 
$results = array(); 
foreach ( $sports as $sport => $url ) { 
  //get the page pointed to by $url 
    $page = file_get_contents($url); 
    //grab all variables out of the page 
    preg_match_all("/&([^=]+)=([^&]+)/", urldecode($page), $foo); 
    //loop through all the variables on the page 
    foreach ( $foo[1] as $key => $value ) { 
      //debug output, you can delete this next line 
      //echo "{$value} = {$foo[2][$key]}\t<br />\n"; 
    //this chain of IF/elseif statements is used to determine which pattern to use 
    //to strip out the correct data, since each sport seems to have its own format 
    //for the variables you'd "want" 
      if ( $sport == 'URL' && preg_match("/s_url\d+/", $value) ) { 
       $results[$sport][] = $foo[2][$key]; 
      } 
    elseif ( $sport == "NHL" && preg_match("/s_left\d+/", $value) ) { 
      $results[$sport][] = $foo[2][$key]; 
    }  
    }   
     
} 

//calculate the sport with the most number of rows 
$limit = 0; 
foreach ( $results as $countMe ) { 
  $limit = max($limit, count($countMe)); 
} 

//spit out the table with the right headers 

echo '<img src="nhl.jpg">';
echo "<table border=1 cellpadding=2><tr><th>" . implode("</th><th>", array_keys($sports)) . "</th></tr>"; 
//loop until you reach the max number of rows, printing out all the table rows you want 
for ( $p = 0; $p < $limit; $p++ ) { 
  echo "<tr align=center>"; 
  foreach ( array_keys($sports) as $sport ) { 
    echo "<td>{$results[$sport][$p]}</td>"; 
  } 
  echo "</tr>"; 
} 
//kill the table 
echo "</table>";

that sepparated all the info for the current day. that part is fine how i had it. im trying to get fri, sat, sun and mon to be side by side.

the part that says

$weather->display();}

i believe this is just running a loop on the data??

i think this is where i am failing

May 28, 2010

i think im getting closer.

index.php:

i know how to make links, but the url column is being parsed from a url string and then placed in the table. im not sure how to make it a link rather than just text.

May 26, 2010

2 questions... in my code, where would i put my style, ie. background colors, etc.

second question, how would i make the second column (url) an actual link?

here is my code:

<?php 
//this array contains sports and their URLs 
$sports = array( 
"MLB" => "http://sports.espn.go.com/mlb/bottomline/scores",
"URL" => "http://sports.espn.go.com/mlb/bottomline/scores"); 
$results = array(); 
foreach ( $sports as $sport => $url ) { 
  //get the page pointed to by $url 
    $page = file_get_contents($url); 
    //grab all variables out of the page 
    preg_match_all("/&([^=]+)=([^&]+)/", urldecode($page), $foo); 
    //loop through all the variables on the page 
    foreach ( $foo[1] as $key => $value ) { 
      //debug output, you can delete this next line 
      //echo "{$value} = {$foo[2][$key]}\t<br />\n"; 
    //this chain of IF/elseif statements is used to determine which pattern to use 
    //to strip out the correct data, since each sport seems to have its own format 
    //for the variables you'd "want" 
      if ( $sport == 'URL' && preg_match("/s_url\d+/", $value) ) { 
       $results[$sport][] = $foo[2][$key]; 
      } 
    elseif ( $sport == "MLB" && preg_match("/s_left\d+/", $value) ) { 
      $results[$sport][] = $foo[2][$key]; 
    }  
    }   
     
} 

//calculate the sport with the most number of rows 
$limit = 0; 
foreach ( $results as $countMe ) { 
  $limit = max($limit, count($countMe)); 
} 

//spit out the table with the right headers 
echo '<img src="mlb.gif">';
echo "<table border=1 cellpadding=2><tr><th>" . implode("</th><th>", array_keys($sports)) . "</th></tr>"; 
//loop until you reach the max number of rows, printing out all the table rows you want 
for ( $p = 0; $p < $limit; $p++ ) { 
  echo "<tr align=center>"; 
  foreach ( array_keys($sports) as $sport ) { 
    echo "<td>{$results[$sport][$p]}</td>"; 
  } 
  echo "</tr>"; 
} 
//kill the table 
echo "</table>";

thanks,

mike

May 26, 2010

hi, im hoping i can cleanup my results and then make a new page that can place the results in a nice table. here is my code:

<?php


$content1 = file_get_contents('http://sports.espn.go.com/mlb/bottomline/scores');
parse_str($content1,$vars);


echo '<pre>'.print_r($vars, true).'</pre>'; 




?>

page can be seen at http://durhamit.ca/test/test.php

May 26, 2010

how about taking this data and dividing it into each game and outputting as rss page? is that easy?

May 26, 2010

im slowly getting it now. is it easy to put groups into a table? or should i just be paying someone to do this for me?

May 26, 2010

i feel even dumber now... i made a new file called test and i put this in it:

<?php
$content = file_get_contents('http://sports.espn.go.com/mlb/bottomline/scores');
parse_str($content,$vars);
?>

i get nothing when i try open that page now. did i screw it up?
