s0c0 Posted March 3, 2007 Share Posted March 3, 2007 For my application I need to allow the user to select multiple mysql records via an html form checkbox. On submission of the form I would like to store these values in an array for either multiple record deletion or creating a list of records. Here is what the form code looks like: /* loop throgh user's mp3s and create html table row for each */ for($i=0; $i<$num_results; $i++) { $row = $result->fetch_assoc(); echo "<tr>"; echo "<td><input type='checkbox' name='track[]' value='". $row['id'] ."'></td> \n"; // radio value is mp3.id echo "<td><a href='" . $row['file'] . "'>" . $row['song'] . "</a></td> \n"; //link is mp3 file echo "<td>" . $row['artist'] . "</td> \n"; echo "<td><a href=\"javascript:popUp('myupdate.php?id=". $row['id'] ."&uid=". $uid ."')\">Update</a></td> \n"; //echo "<td>" . $row['genre'] . "</td> \n" ; //echo "<td>" . $row['playtime'] . "</td> \n"; //echo "<td>" . $row['playlist'] . "</td>"; echo "</tr> \n"; } echo "</table> \n"; Here is where the array code needs to be: if (isset($_POST['submit'])) { /* $queryTrack = "SELECT * FROM mp3 WHERE id='$_POST[track]'"; $delTrack = mysqli_query($db, $queryTrack); while ($row = mysqli_fetch_array($delTrack)) { $file = $row['file'] ."<br/>"; $fullpath = $docroot . $row['file']; unlink($fullpath); } $queryID = "DELETE FROM mp3 WHERE id='$_POST[track]'"; $idResult = mysqli_query($db, $queryID); header("Location:mymusic.php"); */ } For the life of me I cannot figure out how to do this. I've tried the following type stuff just to get a hang of it, but I get an error like Invalid argument supplied for foreach() foreach($track as $tid) { echo $tid; } Quote Link to comment Share on other sites More sharing options...
s0c0 Posted March 3, 2007 Author Share Posted March 3, 2007 Okay I gave up on myself to early once again. Here's the solution. You still need to post your checkbox form data so php knows what your talking about. In my case I would write the following near the top of my code with the rest of my variables: $track = $_POST["track"]; That's how I got it too work. My that's simple!
