So I've created a form that allows an estate agent to store customer information. I am now trying to allow this information to be edited in a HTML form. I can't figure out how to get the selected row to be echoed into my form fields and then updated back into the database. Here is my code so far.

 

if (isset($_POST['showcatalogue']))
{
$showallcustomers = "SELECT * from CustomerTable";
$allcustomerresults = mysql_query($showallcustomers);
echo"<div class='page-restrict-output'>";
echo "<form method='post' action='customer-viewer'>";
echo "<input id='editcustomerbutton' type='Submit' name='editcustomerbtn' value='Edit Customer' /><br><br /></td></tr>";
echo "Here are the results, Select only ONE Customer to edit or the operation will FAIL. <br>";
echo "<br>";
echo"<table id='selectcustomertable' border='1'>"; 
echo "<tr><th>FirstName</th><th>SecondName</th><th>Address Line 1</th><th>Address Line 2</th><th>Address Line 3</th><th>Post Code</th><th>Customer ID</th><th>Phone Number</th><th>E-Mail</th><th>Edit Customer</th></tr>"; 
while($row = mysql_fetch_array($allcustomerresults)) { 
echo "<tr><td>"; 
echo $row['FirstName']; 
echo "</td><td>";
echo $row['SecondName'];  
echo "</td><td>";
echo $row['AddressLine1'];  
echo "</td><td>";
echo $row['AddressLine2'];  
echo "</td><td>";
echo $row['AddressLine3'];  
echo "</td><td>";
echo $row['PostCode'];  
echo "</td><td>";
echo $row['CustomerID'];  
echo "</td><td>";
echo $row['PhoneNumber'];  
echo "</td><td>";
echo $row['EMail'];  
echo "</td><td>";
echo $row['EditCustomer']; 
echo "<input id='selectcustomerbutton' type='checkbox' name='selectedCustomerIDS[]' value='$row[CustomerID]'  /></td></tr>";
echo" </form>";
echo "</div>";


}
$_POST['selectedCustomerIDS'];
{
echo "<form id=alleditcustomerform action='customer-viewer' autocomplete='on' method='post' onsubmit='return(validatecustomer());' >";
echo "<input type='hidden' name='savechanges' value='true' />";
echo "<br>";
foreach($_POST['selectedCustomerIDS'] as $CustomerIDforedit){
echo " You have selected Customer Number $CustomerIDforedit";
$theselectedrow = "SELECT row from CustomerTable WHERE '$CustomerIDforedit' = '$CustomerID'";

The way you are trying to print the value from $row is like this:

 

$row[FirstName]

It needs to be like this:

 

$row['FirstName']

 

Notice the quotes. Easy to miss that because you have a tonne of single and double quotes going on in your code.

 

Give that a try and see if it helps.

Try this then:

echo "<input id='FirstName' type='text' maxlength='20' name='FirstName' value='".$row['FirstName']."' pattern='^[a-zA-Z]{2,20}$' required /><br>";

Oh and don't change all of your input fields, just change one, until you get that one working, then apply the same changes to the rest. Will save you a tonne of time debugging

Ok I've made some changes since I notice a issue with my SQL Query but it still doesn't work. I get the same issue. The $row = Null according to the var dump. 

 

The new code is below.

 


 
 
 
 
if (isset($_POST['showcatalogue']))
{
$showallcustomers = "SELECT * from CustomerTable";
$allcustomerresults = mysql_query($showallcustomers);
echo"<div class='page-restrict-output'>";

That might be the issue, here is what I think it should be doing. The CustomerID for this test in the database is 13. If I do 

SELECT * FROM `CustomerTable` WHERE `CustomerID` = 13

in phpmyadmin. I get the result returned.

 

The ID that it taken from the form is stored in $CustomerIDforedit. I echo this out after a customer is selected and that also says 13, or whatever ID corresponds the record you have selected. So when I select from the database using

$theselectedrow = "SELECT * from CustomerTable WHERE 'CustomerID' = '$CustomerIDforedit'";

that should select the Customer ID from the database that is equal to the number stored in $CustomerIDforedit. So if $CustomerIDforedit is echoing out 13 it should select record 13.

Here you have not got the results from the query. You have only queried the database

$theselectedrow = "SELECT * from CustomerTable WHERE 'CustomerID' = '$CustomerIDforedit'";
$theselectedrowresults = mysql_query($theselectedrow);
$count = mysql_num_rows($theselectedrowresults);

You need to get the results from the query using one of the mysql_fetch_* functions. Eg

$row = mysql_fetch_assoc($theselectedrowresults);
// echo the form for editing record

If your query returns multiple results, then you'll need to use a while loop

while($row = mysql_fetch_assoc($theselectedrowresults))
{
    // echo form for editing record
}

After.

I've done some more editing, I've changed the query to 

$theselectedrow = "SELECT * from CustomerTable WHERE 'CustomerID' = '13'";

As I know this works and selects the record in phpmyadmin. But here I get no result again just bool(false).

 

So your code is this

$theselectedrow = "SELECT * from CustomerTable WHERE 'CustomerID' = '13'";
var_dump($row);die();

Then, it will always be null. Because a) you have not executed the query and b) you haven't define $row.

Ok, check to make sure your query is returning an error.

$theselectedrow = "SELECT * from CustomerTable WHERE 'CustomerID' = '13'";
$theselectedrowresults = mysql_query($theselectedrow);

if(!$theselectedrowresults)
{
   echo '<p><b>Database error:</b> ' . mysql_error() . '</p>';
}
else
{
    if(mysql_num_rows($theselectedrowresults))
    {
        $row = mysql_fetch_assoc($theselectedrowresults);
        var_dump($row);
    }
    else
    {
        echo 'No results returned from query';
    }
}
