I am creating a web site with three components. (I'll be adding JQuery and CSS, but for now I'm just trying to solve some basic mechanics)
My structure is :
Below is my code:
html:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript" src="RipListQuery.js"></script>
<title>CD Riplist Query</title>
</head>
<body onload="getArtists()">
<h1>CD Riplist Query</h1>
<div id="divArtists" >
</div>
</body>
</html>
Javascript:
function getArtists() {
xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET","dataAccess.php",false);
xmlhttp.send();
document.getElementById("divArtists").innerHTML=xmlhttp.responseText;
}
php:
<?php
$con = mysql_connect('myServerAddress', 'ainsworthremote', 'myPassword');
if (!$con) {
die("Could not connect: " . mysql_error());
}
$response =
"<table border='1' id='Artists'><thead><tr><th>Artist</th><th>Albums</th></tr></thead><tbody>";
mysql_select_db("ainsworthremote", $con);
$sql="SELECT artist, COUNT(*) AS albums FROM CD_RipList GROUP BY artist ORDER BY artist ";
$result=mysql_query($sql);
while ($row = mysql_fetch_array($result)) {
$response = $response . "<tr>" .
"<td>" . $row['artist'] . "</td>" .
"<td>" . $row['albums'] . "</td>" .
"</tr>";
}
$response = $response . "</tbody></table>";
mysql_close($con);
echo $response;
?>
Instead of getting a table filled with artist names as expected, I get the following:
CD Riplist Query
ArtistAlbums"; mysql_select_db("ainsworthremote", $con); $sql="SELECT artist, COUNT(*) AS albums FROM CD_RipList GROUP BY artist ORDER BY artist "; $result=mysql_query($sql); while ($row = mysql_fetch_array($result)) { $response = $response . "" . "" . $row['artist'] . "" . "" . $row['albums'] . "" . ""; } $response = $response . ""; mysql_close($con); echo $response; ?>
What I want to know (besides what I'm doing wrong) is: What happened to my tags?
Your while statement doesn't make sense, and even if it did you should have the equals '==' operator not '='. You are returning an array from the SQL request, so you need to iterate over that array. Also, when appending to and existing str variable you can use the ".=" operator, an example would be
$response .= "</tbody></table>";
And your while loop could be a foreach loop instead.
$query = mysql_query($sql);
$result = mysql_fetch_array($result);
foreach($result as $row){
$response .= "<tr>" .
"<td>" . $row['artist'] . "</td>" .
"<td>" . $row['albums'] . "</td>" .
"</tr>";
}
$response .= "</tbody></table>";
echo $response;
See if that helps. On top of that you may have some quote escaping issues, though it looks ok.
