Hello. I have displayed data from SQL Table in the HTML form and I want to use this same form to update COMMENT field in the sql. I have already coded my page as follows;

<?php

// Connect to server and select databse.
$con=mysql_connect("localhost", "root", "")or die("cannot connect");
mysql_select_db("ison",$con)or die("cannot select DB");

if(isset($_POST["button"]))



    {


$sql="UPDATE customer SET
COMMENT='$_POST[COMMENT]' WHERE MSISDN='$MSISDN'";
if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
  else
  {
      echo '<span style="color:#6f892c;">RECORD INSERTED SUCCESSFULLY...</span>';
      header("location:index.php");
  }
}

$result = mysql_query("SELECT * FROM customer");

?>

The problem is that even after submit button, there is no update, and am getting SUCCESSFULLY UPDATED results.
Can someone assist please.

Print out your sql statement and if it looks ok would be a good place to start.

I don't do PHP but the Where statement looks suspicious to me.

wht do you mean sir please

echo your $sql to see what it actually is.

Looks like $MSISDN is not given a value, so the query works but does not find any matching rows.

Next to that, directly injecting a comment into your query is likely to break it, for example when using apostrophes. You really need to do some sanitizing.

Dave I have included an echo to $sql but nothing happens. Pritaeas kindly expound your ans by giving an example please.

Something like this I think?

$sql="UPDATE customer SET COMMENT='$_POST[COMMENT]' WHERE MSISDN= '$_POST[MSISDN]';"

Dave av used this sql but am getting Undefined index: MSISDN in line 8

Does this form render multiple rows with multiple comment boxes?

Not. This is the attachment of the form form.png

The comment field is the oner that I want to update

Ok thought so.

So when you post back, you need to update all comments right? It looks like you are just running one sql statement at the moment right?

Sure. But the field that I nid it be updated is the COMMENT field. But if we can update them all at the same time it will be fine. I need the form to do the update

Ok its a bit more complicated that it first appeared then.

I'm off out now,might be able to help later. Meanwhile maybe someone else cn help?

Sure. Anyone with this idea can assist please. I need to launch this application by the end of the day

I'm back now. Can you show me the rendered html - the view source - this will make it easy for me to explain what you need to do.

Ok this is the code that is inserting the data into the sql table before getting the sql table displayed in the html form.

<?php
error_reporting(0);
$connection = mysql_connect("localhost", "root", ""); // Establishing connection with server..
$db = mysql_select_db("ison", $connection); // Selecting Database.
//Array to store validation errors
    if ($_SERVER['REQUEST_METHOD']=='POST') {
    $errmsg_arr = array();

    //Validation error flag
    $errflag = false;

        //Function to sanitize values received from the form. Prevents SQL injection
    function clean($str) {
        $str = @trim($str);
        if(get_magic_quotes_gpc()) {
            $str = stripslashes($str);
        }
        return mysql_real_escape_string($str);
    }
    foreach ($_POST as $key => $val) {
      $form[$key] = htmlspecialchars($val);
    }
        //Sanitize the POST values

    $MSISDN = clean($_POST['MSISDN']);
    $CUSTOMERNAME = clean($_POST['CUSTOMERNAME']);

    //Input Validations

    if($MSISDN == '') {
        $errmsg_arr[] = 'MSISDN missing';
        $errflag = true;
    }
    if($CUSTOMERNAME == '') {
        $errmsg_arr[] = 'CUSTOMERNAME missing';
        $errflag = true;
    }
    }
if(isset($_POST["button"]))
{
$MSISDN=$_POST['MSISDN'];
$query = "SELECT * FROM `customer` WHERE `MSISDN` = '{$MSISDN}'";
$result = mysql_query($query);
$sql="INSERT INTO customer (MSISDN, CUSTOMERNAME, TIME, COMPANY, REASON,CLOSED,COMMENT)
VALUES('$_POST[MSISDN]','$_POST[CUSTOMERNAME]','$_POST[TIME]','$_POST[COMPANY]','$_POST[REASON]','$_POST[CLOSED]','$_POST[COMMENT]')";
header('Location: index.php');
      echo '<span style="color:#6f892c;">RECORD INSERTED SUCCESSFULLY...</span>';
if (!mysql_query($sql,$connection))
  {
  die('Error: ' . mysql_error());
  }
  else
  {    header('Location: index.php');
      echo '<span style="color:#6f892c;">RECORD INSERTED SUCCESSFULLY....</span>';

  }
}

$result = mysql_query("SELECT * FROM customer");

Sorry you have misunderstood what I asked for.

If you run your code so you are viewing the other page in your browser and then you view the source - ie the rendered html - then show me that please.

Thanks

When I run the code, it fetches the data from the sql table as shown in the screen shot below and displays it in html form.
wwwp.png

So my rendered page starts from

$result = mysql_query("SELECT * FROM customer");
<form method="post" action="">
<table width="1200" border="1" cellspacing="1" cellpadding="0">
<tr>
<td>
<table width="1200" border="1" cellspacing="1" cellpadding="3">
<tr>
</tr>
<tr>
<td align="center"><strong>S.NO</strong></td>
<td align="center"><strong>MSISDN</strong></td>
<td align="center"><strong>CUSTOMERNAME</strong></td>
<td align="center"><strong>TIME</strong></td>
<td align="center"><strong>COMPANY</strong></td>
<td align="center"><strong>REASON</strong></td>
<td align="center"><strong>CLOSED</strong></td>
<td align="center"><strong>COMMENT</strong></td>
</tr>
<?php
while($rows=mysql_fetch_array($result)){
?>
<tr>
<td><?php echo $rows['S_NO']; ?></td>
<td><?php echo $rows['MSISDN']; ?></td>
<td><?php echo $rows['CUSTOMERNAME']; ?></td>
<td><?php echo $rows['TIME']; ?></td>
<td><?php echo $rows['COMPANY']; ?></td>
<td><?php echo $rows['REASON']; ?></td>
<td><input name="CLOSED" type="checkbox" id="CLOSED" value="" size="15" checked /> Closed</td>
<td><input name="COMMENT" type="text" id="COMMENT" value="<?php echo $rows['COMMENT']; ?>" size="15"/>
</td>
<?php
}
?>
</table>
</td>
</tr>
</table>
<input type="submit" name="button" id="button" value="Submit" /></td></tr>
</form>

Dave You got it?

Thsi isn't rendered html. It has php code in. Do you understand what rendered html is?

Kindly expound this for me Dave. I think av not understood. What is happening is tht my table is directly fetched from the sql table. it has only that single page to extract that information to display it in an HTML form. Now the problem is that this form needs to update thesame table back to the server.

I got it Dave I think this will give you a greenlight

Ok excellent!

Ok let me take a look...

Good. am waiting brother

Ok so the problem is when you post this form back you get a load of posted values all with the same name "Comment" - see my screenshot below.

So how do you know which record to update? What you need to do is give your form fields a name which identifies the row - eg Comment_1, Comment_2 etc.

Then you can parse the posted data and for each Comment update the correct record by parsing out the row id.

Does that help?

Sorry no I don't have a php development environment setup. Is this for your job or are you a student?
