PHP: Cara Menghapus Multiple Rows dari Mysql Menggunakan Checkbox

Berikut adalah contoh cara menghapus beberapa baris table sehingga mempermudah user untuk melakukan pendeletetan data sesui data yang ingin dihapus.

Step 1
  1. Kita buat table dengan nama "test_mysql" kemudian database kita kasi nama "test" (table test_mysql buat di dalam database tes).
  2. Kemudian kita buat file dengan nama "delete_multiple.php"
Kita buat table "test_mysql" :
----
CREATE TABLE `test_mysql` ( 
`id` int(4) NOT NULL auto_increment, 
`name` varchar(65) NOT NULL default '', 
`lastname` varchar(65) NOT NULL default '', 
`email` varchar(65) NOT NULL default '', 
PRIMARY KEY (`id`) 
) TYPE=MyISAM AUTO_INCREMENT=7 ;
 -- 
 -- Dumping data for table `test_mysql` 
 -- 
 INSERT INTO `test_mysql` VALUES (1, 'Billly', 'Blueton', 'bb5@phpeasystep.com'); 
 INSERT INTO `test_mysql` VALUES (2, 'Jame', 'Campbell', 'jame@somewhere.com'); 
 INSERT INTO `test_mysql` VALUES (3, 'Mark', 'Jackson', 'mark@phpeasystep.com'); 
 INSERT INTO `test_mysql` VALUES (4, 'Linda', 'Travor', 'lin65@phpeasystep.com'); 
 INSERT INTO `test_mysql` VALUES (5, 'Joey', 'Ford', 'fordloi@somewhere.com'); 
 INSERT INTO `test_mysql` VALUES (6, 'Sidney', 'Gibson', 'gibson@phpeasystep.com');
----

Output
Kemudian kita lanjut lagi membuat file "delete_multiple.php":
----
<?php
$host="localhost"; // Host name 
$username=""; // Mysql username 
$password=""; // Mysql password 
$db_name="test"; // Database name 
$tbl_name="test_mysql"; // Table name 

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

$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">&nbsp;</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>Name</strong></td>
 <td align="center" bgcolor="#FFFFFF"><strong>Lastname</strong></td>
 <td align="center" bgcolor="#FFFFFF"><strong>Email</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['id']; ?></td>
 <td bgcolor="#FFFFFF"><? echo $rows['name']; ?></td>
 <td bgcolor="#FFFFFF"><? echo $rows['lastname']; ?></td>
 <td bgcolor="#FFFFFF"><? echo $rows['email']; ?></td>
</tr>

<?php
}
?>

<tr>
 <td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit" id="delete" value="Delete"></td>
</tr>

<?php
// Check if delete button active, start this 
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 successful redirect to delete_multiple.php 
if($result){
echo "<meta http-equiv="refresh" content="0;URL=delete_multiple.php">";
}
}
mysql_close();
?>
</table>
