Today we had to fix a clients PHPlist. There was an error in their mysql select statement for whatever reason – whether it was their setup (they had some really weird group names and country names) or something with PHPList. Took us a while to figure it out, but as it turns out someone else had the same issue.

Basically the fix is this:

# nano /lists/admin/send_core.php

Find this

if (is_array($_POST["criteria_values"])) {
$values = join(“, “,$_POST["criteria_values"]);
} else {
$values = $_POST["criteria_values"];
}

and replace it with this

if (is_array($_POST["criteria_values"])) {
# The following code checks for null values in the criteria_attribute array and removes them
$values = $_POST["criteria_values"];
foreach ($values as $key=>$value) {
if (!$value) {
array_splice($values, $key, 1); // Remove null value from array
}
}
$values = join(“, “,$values);
# $values = join(“, “,$_POST["criteria_values"]);
} else {
$values = $_POST["criteria_values"];
}

Now everything should work, with no more mysql errors!
