populating form with mysql data - php

Question

Hopefully someone can help with my problem, I have a database using MySQL and I have a form that posts to the database, this all works fine.
I have created a customer look up form using HTML and PHP that echos a table and then the table is filled with the MySQL data, again this all works OK.
My problem is that I would like to click the table row or text in that row which ever and open it in a HTML form and include all the data from the row in the MySQL database.
<div id="content">
<h3>Customer Lookup</h3>
<?php
$con=mysqli_connect("localhost","root","","repairsdb");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM customers");
echo "<table border='1'>
<tr>
<th>First Name</th>
<th>Surname</th>
<th>Address</th>
<th>Postcode</th>
<th>Landline</th>
<th>Mobile</th>
</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['firstname'] . "</td>";
echo "<td>" . $row['surname'] . "</td>";
echo "<td>" . $row['addressl1'] . "</td>";
echo "<td>" . $row['postcode'] . "</td>";
echo "<td>" . $row['landline'] . "</td>";
echo "<td>" . $row['mobile'] . "</td>";
echo "<td>" . $row['businessname'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($con);
?>
<FORM>
</FORM>
</div>

</form>

Answer 1

The easiest way to do this would be to open the form in a new page. So to do this we would start by adding a link to your table.
I'm going to assume that in your database you have an unique ID for each customer - we will use this in the link:
echo "<tr>";
echo "<td><a href='/customer_form.php?customer_id=" . $row['ID'] . "'>" . $row['firstname'] . "</a></td>";
echo "<td>" . $row['surname'] . "</td>";
echo "<td>" . $row['addressl1'] . "</td>";
echo "<td>" . $row['postcode'] . "</td>";
echo "<td>" . $row['landline'] . "</td>";
echo "<td>" . $row['mobile'] . "</td>";
echo "<td>" . $row['businessname'] . "</td>";
echo "</tr>";
As you can see I have named the new page customer_form.php. And we will pass the ID to this page via the URL, like so.
www.example.com/customer_form.php?customer_id=3
In your new customer_form.php page you will first need to retrieve the ID from the URL.
if( isset( $_GET['customer_id'] ) ) {
$customer_id = $_GET['customer_id'];
}
Then we will modify this block of code a little more to retrieve the customer from the database, using the ID, and then we can add this data to a new form.
if( isset( $_GET['customer_id'] ) ) {
$customer_id = $_GET['customer_id'];
$result = mysqli_query($con,"SELECT * FROM customers where ID = " . $customer_id . " Limit 1");
echo '
<form method="post">
<input type="text" name="firstname" value="'. $result['firstname'] .'" />
<input type="text" name="surname" value="'. $result['surname'] .'" />
<input type="text" name="addressl1" value="'. $result['addressl1'] .'" />
<input type="text" name="postcode" value="'. $result['postcode'] .'" />
<input type="text" name="landline" value="'. $result['landline'] .'" />
<input type="text" name="mobile" value="'. $result['mobile'] .'" />
<input type="text" name="businessname" value="'. $result['businessname'] .'" />
</form>
';
}
You could do it other ways, in a pop up window, or even on the same page using JavaScript. But this is the least complicated.
I should note that the SQL query I wrote would be vulnerable to SQL injection, since it takes a value from the address bar and injects it directly into the query. But it's a little outside of the scope of the question, so I suggest you look it up if interested.

Answer 2

sounds like this would work...
use clicks on link (selects something in)
then - jqueryAJAX POSTs FORM
then - php processPOST
then - mysql getDataFrom DB
then - php process MYSQL results && echo $jsoResults
then - jqueryAJAX process results open new Form with inputs populated...

I managed to sort the errors, I have posted the code for anyone having the same problem. I have answered this question myself only for the reason so I can post the final code, but the credit has to go to #user1100149 and also a chap on YouTube.
