Update specific fields in SQL using PHP

[nic0]

Hi all, i'm very new to this and would greatly appreciate any help.

 

I need help on a form which a user can enter a specific customers name and then update a specific field based on their name.

 

i.e. if I enter the customer name Bob into a text box and enter his age in another text box I need the PHP script to look for Bob then update this age.

 

First Page shows a table from the database so the user can see whos in it:

 

<?php
$con = mysql_connect("***","***","**");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("***", $con);

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

echo "<form name='update' action='606.php' method='post'>
<h2>Update Order Status</h2><br><table border='1'>
<p>Current Customer Status</p>
<tr>
<th>FirstName</th>
<th>Order Stage</th>
</tr>";

while($row = mysql_fetch_array($result))
  {
  echo "<tr>";
  echo "<td>" . $row['FirstName'] . "</td>";
  echo "<td>" . $row['Stage'] . "</td>";
  echo "</tr>";
  }
echo "</table><br><p>Customer Name<p><input type='text' name='n1'><br><p>Order Stage<p><input type='text' name='n2'><br><input type='submit' name='submit' value='Update' />";

mysql_close($con);
?> 

 

Which then runs 606.php

 

<?php
$con = mysql_connect("***","***","***");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("***", $con);

//what goes here?
WHERE FirstName = $_POST['n1.TEXT']");

mysql_close($con);
?> 

 

So in this example i would like to enter Bob into the text box n1, then from this update his order stage from text box n2.

 

Can anyone help?

Hi

 

You would use something like:-

 

<?php
$con = mysql_connect("***","***","***");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("***", $con);

//what goes here?
UPDATE sometable SET order_stage = '".$_POST['n2']."' WHERE FirstName = '".$_POST['n1']."'";

mysql_close($con);
?>  

 

However you should validate the input first (and use mysql_real_escape_string to avoid problems with people putting quotes and dodgy sql in the input fields).

 

All the best

I would not use this approach as what if your customer's name is Alidimagit or some other name you might find hard writing. Instead display all users in a table add a button to edit the user's age which passes the user's id
