I have to migrate code originally built using your tools in PHP v.5.0 to v.7.1.

I was able to to establish connection as such -

Connection file:

ORIGINAL IN V.5
$hostname_exhibitions_cx = "00.00.00.000";
$database_exhibitions_cx = "my-database-name";
$username_exhibitions_cx = "GGGGGGG";
$password_exhibitions_cx = "GGGGGGG";
$exhibitions_cx = mysql_pconnect($hostname_exhibitions_cx, $username_exhibitions_cx, $password_exhibitions_cx) or trigger_error(mysql_error(),E_USER_ERROR);

I CHANGED TO V.7
$hostname_exhibitions_cx = "00.00.00.000";
$database_exhibitions_cx = "my-database-name";
$username_exhibitions_cx = "GGGGGGG";
$password_exhibitions_cx = "GGGGGGG";
$exhibitions_cx = new mysqli('hostname_exhibitions_cx', 'username_exhibitions_cx', 'password_exhibitions_cx!', 'database_exhibitions_cx'); ?>

BUT IS CODE BELOW CORRECT ON V.7? I CANT' GET THE DATA TO SHOW

CODE

ORIGINAL IN V.5 IN THE DATA FILE

mysql_select_db($database_exhibitions_cx, $exhibitions_cx);
$query_Recordset1 = "SELECT * FROM sangiacomoexhibitions_tbl WHERE RemovalDate > NOW() ORDER BY RemovalDate ASC";
$Recordset1 = mysql_query($query_Recordset1, $exhibitions_cx) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);


I CHANGED TO V7

$exhibitions_cx->select_db(database_exhibitions_cx, $exhibitions_cx);
$query_Recordset1 = $exhibitions_cx->query("SELECT * FROM sangiacomoexhibitions_tbl WHERE RemovalDate > NOW() ORDER BY RemovalDate ASC");
$Recordset1 = mysqli_query($query_Recordset1, $exhibitions_cx);
$row_Recordset1 = mysqli_fetch_row($Recordset1);
$totalRows_Recordset1 = mysqli_num_rows($Recordset1)




HERE'S DATA THAT SHOULD BE DISPLAYED: WHAT NEEDS CHANGING FOR THIS? ALL I GET ON THE PAGE IS THE STATEMENT ""Updating. Please check back later".


<?php

$date = date('Y/m/d');
$mydate = date("Y/m/d",strtotime($row_Recordset1['RemovalDate']));

$Recordset1_endRow = 0;
$Recordset1_columns = 3; // number of columns
$Recordset1_hloopRow1 = 0; // first row flag
do {
if($Recordset1_endRow == 0 && $Recordset1_hloopRow1++ != 0) echo "<tr>";
?>
<?php

if ($mydate < $date) {

echo "Updating. Please check back later";
} else {
do {
echo "<div class='exhibitionswrap'>";
echo "<div class='exhibitions'>";
echo '<p>';
$image = '<img src="images/exhibitions/' . $row_Recordset1['Logoimg'] . '">';
echo "<a target='_new' href=" . "http://" . $row_Recordset1["Website"] . ">" ;
echo "" .$image."";
echo "</a>";
echo '</p>';
echo '<p>';
echo $row_Recordset1["Eventdate"];
echo '<br>';
echo $row_Recordset1["Location"];
echo '</br>';
echo "<a target='_new' href=" . "http://" . $row_Recordset1["Website"] . ">" ;
echo $row_Recordset1["Website"];
echo "</a>";
echo '<br>';
echo '<br>';
echo "</div>";
echo "</div>";

} while ($row_Recordset1 = mysqli_fetch_assoc($Recordset1));
}
?>
<?php $Recordset1_endRow++;
if($Recordset1_endRow >= $Recordset1_columns) {
?>

<?php
$Recordset1_endRow = 0;
}
} while ($row_Recordset1 = mysqli_fetch_row($Recordset1));
if($Recordset1_endRow != 0) {
while ($Recordset1_endRow < $Recordset1_columns) {
echo("");
$Recordset1_endRow++;
}
}
?>

I'm not sure. I would suggest using our MySQLi server behaviors to create a recordset.

If you need to hand code then you will have to debug to find the problem. Maybe add:
<?php
var_dump($row_Recordset1);
?>

To see if the recordset has the data you expect. I think it might be that this:

$query_Recordset1 = $exhibitions_cx->query("SELECT * FROM sangiacomoexhibitions_tbl WHERE RemovalDate > NOW() ORDER BY RemovalDate ASC");
$Recordset1 = mysqli_query($query_Recordset1, $exhibitions_cx);

should just be:
$Recordset1 = $exhibitions_cx->query("SELECT * FROM sangiacomoexhibitions_tbl WHERE RemovalDate > NOW() ORDER BY RemovalDate ASC");

Where can I get your MSQLI server behavior? Will it regenerate the code for PHP 7?

It won't regenerate your code, but it will give you access to all of the standard database server behaviors that originally shipped with dreamweaver in mySQLi versions. So you can recreate recordsets, loops and use the bindings window to add recordset values to your page. It also has all of the insert, update, and delete server behaviors for you to use.
