Hi all,
I have a database with contact info, and I need to display the info in groups. Currently in my database table called contacts I have a field called 'groups'. The values are 'favorites', 'home', 'work', and 'friends'.
I tried creating a page called group.php and used a dropdown box to select the group, and as per the value in the dropdown box, the affected rows from the SQL database should appear. However I'm presented with a error:
mysql_fetch_array(): supplied argument is not a valid MySQL result resource
And here is my code from groups.php.
<?php
include ("dbConfig.php");
require ("check.php");
?>
<div align ="center">
Welcome <?php $_SESSION["valid_user"] ?> Not you? <a href=http://localhost/cas/logout.php\">Click here.</a>
<br />
<table align="center" width="1100" border="0">
<tr>
<td width="1000"><div align='center'><h1> Contacts</h1></div></td>
<td width="100">Select a group: <form action="groups.php" method="post"><select name = "chooser">
<option value='all'>All</option>
<option value='favorites'>Favorites</option>
<option value='home'>Home</option>
<option value='work'>Work</option>
<option value='friends'>Friends</option>
</select><input type="submit" value="Select" name="select"></form></td>
</div>
<table align="center" width="1100" border="0">
<tr>
<td width="100"><b>Name</b></td>
<td width="200"><b>Email</b></td>
<td width="100"><b>Age</b></td>
<td width="100"><b>Birthday</b></td>
<td width="400"><b>Address</b></td>
<td width="270"><b>Number</b></td>
<td><b>Photo</b></td>
</tr>
</table>
<?php
//delete check
if(isset ($_GET['id2']))
{
$id2 = $_GET['id2'];
// --------- here code to connect to mysql and select database -----------
$query= mysql_query("delete FROM contacts where id2 = $id2")or die(mysql_error());
}
//store the current user into a variable
$username = $_SESSION["valid_user"];
$group = $_POST['chooser'];
//select table
$result = mysql_query("SELECT id2, name, email, age, birthday, address, number, uploadedfile FROM contacts WHERE username='$username' AND group='$group'");
//grab content
while($r=mysql_fetch_array($result))
{
$id2=$r["id2"];
$name=$r["name"];
$email=$r["email"];
$age=$r["age"];
$birthday=$r["birthday"];
$address=$r["address"];
$number=$r["number"];
$uploadedfile=$r["uploadedfile"];
$self = $_SERVER['PHP_SELF'];
//display the row
echo "<table align=\"center\" width=\"1100\" border=\"0\">";
// echo "<tr>";
// echo "<td width=\"200\"><b>Name</b></td>";
// echo "<td width=\"250\"><b>Email</b></td>";

// echo "<td width=\"200\"><b>Handphone Number</b></td>";
// echo "<td><b>Photo</b></td>";
// echo "</tr>";
echo "<tr>";
echo "<td width=\"100\">$name <a href=\"edit.php?cmd=edit&id2=$id2\">(Edit)</a> | <a href = \"$self?id2=$id2\">(Delete)</a></td>";
echo "<td width=\"200\">$email</td>";
echo "<td width=\"100\">$age</td>";
echo "<td width=\"100\">$birthday</td>";
echo "<td width=\"400\">$address</td>";
echo "<td width=\"200\">$number</td>";
echo "<td><img src=\"http://localhost/cas/uploads/$r[uploadedfile]\"alt=\"\" name=\"\" width=\"100\" height=\"110\" border=\"1\"/></img></td>";
echo "</tr>";
echo "</table>";
echo "<br />";
}
echo "<br />";
echo "<br />";
echo "<div align =\"center\">";
echo "<a href=\"http://localhost/cas/members.php\">Member Home</a>";
echo "</div>";

Please help. Any help would be much appreciated, and this is very urgent. Thank you.
