It seems to work but it doesn't  update, its like nothing happen.

list_records.php 

<?php
$host="localhost"; // Host name 
$username="root"; // Mysql username 
$password="root"; // Mysql password 
$db_name="test"; // Database name 
$tbl_name="test_mysql"; // Table name


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);
?>

<table width="400" border="0" cellspacing="1" cellpadding="0">
<tr>
<td>
<table width="400" border="1" cellspacing="0" cellpadding="3">
<tr>
<td colspan="4"><strong>List data from mysql, <a href='insert.php'>Add New</a> </strong> </td>
</tr>

<tr>
<td align="center"><strong>id</strong></td>
<td align="center"><strong>Name</strong></td>
<td align="center"><strong>Lastname</strong></td>
<td align="center"><strong>Email</strong></td>
<td align="center"><strong>Update</strong></td>
</tr>

<?php
while($rows=mysql_fetch_array($result)){
?>

<tr>
<td><? echo $rows['id']; ?></td>
<td><? echo $rows['name']; ?></td>
<td><? echo $rows['lastname']; ?></td>
<td><? echo $rows['email']; ?></td>


<td align="center"><a href="update.php?id=<? echo $rows['id']; ?>">update</a></td>
<td bgcolor="#FFFFFF"><a href="delete_ac.php?id=<? echo $rows['id']; ?>">delete</a></td>
</tr>

<?php
}
?>

</table>
</td>
</tr>
</table>

<?php
mysql_close();
?>
 

update.php 

############### Code
<?php

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

// get value of id that sent from address bar
$id=$_GET['id'];

// Retrieve data from database 
$sql="SELECT * FROM $tbl_name WHERE id='$id'";
$result=mysql_query($sql);
$rows=mysql_fetch_array($result);

<table width="400" border="0" cellspacing="1" cellpadding="0">

<?php
// close connection 
mysql_close();
?>

and update_ac.php

<?php
$host="localhost"; // Host name 
$username="root"; // Mysql username 
$password="root"; // Mysql password 
$db_name="test"; // Database name 
$tbl_name="test_mysql"; // Table name 

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

// update data in mysql database 
$sql="UPDATE $tbl_name SET name='$name', lastname='$lastname', email='$email' WHERE id='$id'";
$result=mysql_query($sql);

// if successfully updated. 
if($result){
echo "Successful";
echo "<BR>";
echo "<a href='list_records.php'>View result</a>";
}

else {
echo "ERROR";
}

?>

You aren't picking up the POSTed form data

[unasemana]

well i just figure it out , it's cause on the update_ac.php it's not actually $_POST'ing the variables, so adding this will work

 

PHP Code:

$name = $_POST['name'];
$lastname = $_POST['lastname'];
$email = $_POST['email'];
$id = $_POST['id'];  

 

Thanks for your time
