Multiple records Update Problem

Recommended Posts

Hi,

 

I am trying to update multiple records in one of my tables and I can't find the problem why is not updating the table.

Can someone take a look at my code and see what I am doing wrong.

 

Thank you.

My Page:

 

<?php

$host="localhost"; // Host name

$username=""; // Mysql username

$password=""; // Mysql password

$db_name=""; // Database name

$tbl_name="tbl"; // 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";

$result=mysql_query($sql);

 

// Count table rows

$count=mysql_num_rows($result);

?>

<table width="500" border="0" cellspacing="1" cellpadding="0">

<form name="form1" method="post" action="">

<tr>

<td>

<table width="500" border="0" cellspacing="1" cellpadding="0">

 

 

<tr>

<td align="center"> </td>

<td align="center"><div align="left"><strong>Type</strong></div></td>

<td align="center"><div align="center"><strong>Order Type</strong></div></td>

</tr>

<?php

while($rows=mysql_fetch_array($result)){

?>

<tr>

<td align="center"><? $boardTypeID[]=$rows['boardTypeID']; ?></td>

<td align="center"><div align="left"><? echo $rows['type']; ?>

</div>

  <div align="left"></div></td>

<td align="center"><input name="orderType[]" type="text" id="orderType" value="<? echo $rows['orderType']; ?>" size="2"></td>

</tr>

<?php

}

?>

<tr>

<td colspan="4" align="center"><input type="submit" name="Submit" value="Submit"></td>

</tr>

</table>

</td>

</tr>

</form>

</table>

<?php

// Check if button name "Submit" is active, do this

if($Submit){

for($i=0;$i<$count;$i++){

$sql1="UPDATE tbl SET orderType='$orderType[$i]' WHERE boardTypeID='$boardTypeID[$i]'";

$result=mysql_query($sql1);

}

}

 

mysql_close();

?>

Hi newtomysql,

 

The problem is with the following line:

 

if($Submit){

 

It's basically saying if $Submit is set, perform the code below, but nowhere is the $Submit variable defined.  Even if it was, checking for a $_POST request using this method isn't as effective as using the $_SERVER as some browsers don't process it properly.

 

Change it to read:

 

if($_SERVER['REQUEST_METHOD']=='POST'){

 

Hope this helps.
