  1. Hi, sorry I am new here and also very new to PHP & MySQL. this is another script that is trying to do the same thing (deleting rows with checkbox) <?php include "connect.php"; $result = mysql_query("SELECT * FROM users"); if(isset($_POST['delete'])){ if(is_array($_POST['id'])){ echo '<pre>'; print_r($_POST); echo '<pre>'; foreach($_POST['id'] as $id){ $query = "DELETE FROM users WHERE id=".$id; mysql_query($query)or die(mysql_error()); echo "User Deleted"; } } } ?> <form action="<?php $_SERVER['PHP_SELF'] ?>" method="POST"> <? echo "<table border='0'> <tr> <th>Firstname</th> <th>Lastname</th> <th>Location</th> <th>Email</th> <th>Website</th> <th>userID</th> </tr>"; while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['firstname'] . "</td>"; echo "<td>" . $row['lastname'] . "</td>"; echo "<td>" . $row['location'] . "</td>"; echo "<td>" . $row['email'] . "</td>"; echo "<td>" . $row['website'] . "</td>"; echo "<td>" . $row['userID'] . "</td>"; ?> <td><input type="checkbox" name="id[]" value="<?php $row['id'] ?>" /></td> <? echo "</tr>"; } echo "</table>"; echo "<input type='submit' value='Delete Users' name='delete' />"; mysql_close($con); ?> this gives me this error: Array ( [id] => Array ( [0] => ) [delete] => Delete Users ) You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 And the first script does not seem to do anything at all, no error or anything.
  2. Hi guys, I am trying out this code but it does not work, any idea what I am doing wrong? <?php include 'connect.php'; $tbl_name="users"; $sql="SELECT * FROM $tbl_name"; $result=mysql_query($sql); $count=mysql_num_rows($result); ?> <table width="400" border="0" cellspacing="1" cellpadding="0"> <tr> <td><form name="form1" method="post" action=""> <table width="400" border="0" cellpadding="3" cellspacing="1" bgcolor="#CCCCCC"> <tr> <td bgcolor="#FFFFFF"> </td> <td colspan="4" bgcolor="#FFFFFF"><strong>Delete multiple rows in mysql</strong> </td> </tr> <tr> <td align="center" bgcolor="#FFFFFF">#</td> <td align="center" bgcolor="#FFFFFF"><strong>Id</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Firstname</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Lastname</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Location</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Email</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Website</strong></td> </tr> <?php while($rows=mysql_fetch_array($result)){ ?> <tr> <td align="center" bgcolor="#FFFFFF"><input name="checkbox[]" type="checkbox" id="checkbox[]" value="<? echo $rows['id']; ?>"></td> <td bgcolor="#FFFFFF"><? echo $rows['userID']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['firstname']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['lastname']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['location']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['email']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['website']; ?></td> </tr> <?php } ?> <tr> <td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit" id="delete" value="Delete"></td> </tr> <? if($delete){ for($i=0;$i<$count;$i++){ $del_id = $checkbox[$i]; $sql = "DELETE FROM $tbl_name WHERE id='$del_id'"; $result = mysql_query($sql); } if($result){ echo "<meta http-equiv=\"refresh\" content=\"0;URL=showusers2.php\">"; } } mysql_close(); ?> </table> </form> </td> </tr> </table>
