php code not working after php.ini file reset

Question

My service provider reset my php.ini file on me. My php code has not changed but now none of my functions are working?

I am running php.ini 5.2 what would I need to turn on, or off, to get the following code to work again?

Thank you in advance for your help

function characterListPost() {
global $wpdbNew;
$q = "SELECT id, ch_position, ch_name, ch_image, ch_description, ch_age, ch_like, ch_dislike FROM characters ORDER BY ch_position";
$rows = $wpdbNew->get_results($q,ARRAY_A);
// start with nonsense value to force a heading
$previous_season = 0;
$outputTwo='';
$i = 1;
foreach ($rows as $row) {
$outputTwo.= "<div class=\"characterbox\" id=\"div{$i}\">";
$i++;
$outputTwo.= "<div class=\"ch_name\">{$row["ch_name"]}</div>";
$outputTwo.= "<div><image class=\"ch_image\" id=\"ch_image{$row["id"]}\" alt=\"character image TBA\" src=\"{$row["ch_image"]}\" /></div>";
$outputTwo.= "<div class=\"ch_description\"><p>{$row["ch_description"]}</p></div>";
$outputTwo.= "<div class=\"ch_age\"><b>Age:</b> {$row["ch_age"]}</div>";
$outputTwo.= "<div class=\"ch_like\"><b>Like:</b> {$row["ch_like"]}</div>";
$outputTwo.= "<div class=\"ch_dislike\"><b>Dislike:</b> {$row["ch_dislike"]}</div>";
$outputTwo.= "<div class=\"Down10px clear\"></div>";
$outputTwo.= "</div>";
}
// echo test successful but $outputTwo will not display?
echo 'Connected successfully'; 
return $outputTwo;
}
?>

I tested the db code and it works so by process of elimination the problem must be between my php.ini file and the function code above

<?php
$wpdbNew = new wpdb('myacc.myhost.com', 'myusername', 'mypassword', 'mydbname');
if (!$wpdbNew) { 
    die('Could not connect: ' . mysql_error()); 
} 

The following are already On inside php.ini

allow_url_fopen = On
allow_url_include = On
register_long_arrays = On
register_globals = On

Second part, based on provided answer below, getting the following code to work EDIT got it to work by removing foreach ($rows as $row) { All set, everything is working!

<?php
episodeListPost();


function episodeListPost() {
    $host = 'mydomain.com';
    $user = 'myusername';
    $pass = 'mypassword';
    $data = 'dbname';

    $cn = mysql_connect($host, $user, $pass) or die(mysql_error());
    mysql_select_db($data, $cn) or die(mysql_error());
    $sql = "SELECT id, season_num, temp_eps_num, eps_num, title, inspired, descrip FROM season ORDER BY season_num, temp_eps_num";

    $result = mysql_query($sql, $cn) or die(mysql_error());

    if($result) {

        $previous_season = 0;
        $outputOne='';
        $i = 1;

        while($row = mysql_fetch_assoc($result)) {

            foreach ($rows as $row) {
        $season = $row["season_num"];
        if ($season != $previous_season){
        $outputOne.= "<div class=\"seasonTitle\">Season $season</div>";
        $previous_season = $season;
        }
        $outputOne.= "<div class=\"clear\">Episode: {$row["eps_num"]}</div>";
        $outputOne.= "<div class=\"epsTitle\">Title: <span class=\"epsTitleOutput\">{$row["title"]}</span></div><div class=\"epsInsp\"> {$row["inspired"]}</div>";
        $outputOne.= "<div class=\"epsDiscrip\">{$row["descrip"]}</div>";
        $outputOne.= "<div class=\"Down10px\"></div>";
        }

    if($i == 1) { }
        echo $outputOne;
        mysql_free_result($result);
    } else {
        echo 'No results';
    }
    mysql_close($cn);
}
?>

Answer 1

The the following function. Most likely, your query is not returning any results, or the function $wpdbNew->get_results() is not returning any records.

function characterListPost() {
    global $wpdbNew;
    $q = "SELECT id, ch_position, ch_name, ch_image, ch_description, ch_age, ch_like, ch_dislike FROM characters ORDER BY ch_position";
    $rows = $wpdbNew->get_results($q,ARRAY_A);
    // start with nonsense value to force a heading
    $previous_season = 0;
    $outputTwo='';
    $i = 1;
    foreach ($rows as $row) {
        $outputTwo.= "<div class=\"characterbox\" id=\"div{$i}\">";
        $i++;
        $outputTwo.= "<div class=\"ch_name\">{$row["ch_name"]}</div>";
        $outputTwo.= "<div><image class=\"ch_image\" id=\"ch_image{$row["id"]}\" alt=\"character image TBA\" src=\"{$row["ch_image"]}\" /></div>";
        $outputTwo.= "<div class=\"ch_description\"><p>{$row["ch_description"]}</p></div>";
        $outputTwo.= "<div class=\"ch_age\"><b>Age:</b> {$row["ch_age"]}</div>";
        $outputTwo.= "<div class=\"ch_like\"><b>Like:</b> {$row["ch_like"]}</div>";
        $outputTwo.= "<div class=\"ch_dislike\"><b>Dislike:</b> {$row["ch_dislike"]}</div>";
        $outputTwo.= "<div class=\"Down10px clear\"></div>";
        $outputTwo.= "</div>";
    }
    // echo test successful but $outputTwo will not display?
    echo 'Connected successfully.';
    if($i == 1) { echo '<br />' . 'No Rows Found'; } else { echo '<br />' . $i . ' Rows Found'; }
    return $outputTwo;
}

SECOND TEST

<?php
characterListPost();


function characterListPost() {
    $host = '127.0.0.1';
    $user = 'root';
    $pass = '';
    $data = 'test';

    $cn = mysql_connect($host, $user, $pass) or die(mysql_error());
    mysql_select_db($data, $cn) or die(mysql_error());
    $sql = "SELECT id, ch_position, ch_name, ch_image, ch_description, ch_age, ch_like, ch_dislike FROM characters ORDER BY ch_position";

    $result = mysql_query($sql, $cn) or die(mysql_error());

    if($result) {

        $previous_season = 0;
        $outputTwo='';
        $i = 1;

        while($row = mysql_fetch_assoc($result)) {

            $outputTwo.= "\n\n" . '<!--- ROW #' . $i . ' -->' . "\n";
            $outputTwo.= '<div class="characterbox" id="div' . $i . '">' . "\n";
            $i++;
            $outputTwo.= '<div class="ch_name">' . $row["ch_name"] . '</div>' . "\n";
            $outputTwo.= '<div><image class="ch_image" id="ch_image' . $row["id"] . '" alt="character image TBA" src="' . $row["ch_image"] . '" /></div>' . "\n";
            $outputTwo.= '<div class="ch_description"><p>' . $row["ch_description"] . '</p></div>' . "\n";
            $outputTwo.= '<div class="ch_age"><b>Age:</b> ' . $row["ch_age"] . '</div>' . "\n";
            $outputTwo.= '<div class="ch_like"><b>Like:</b> ' .$row["ch_like"] . '</div>' . "\n";
            $outputTwo.= '<div class="ch_dislike"><b>Dislike:</b> ' . $row["ch_dislike"] . '</div>' . "\n";
            $outputTwo.= '<div class="Down10px clear"></div>' . "\n";
            $outputTwo.= '</div>' . "\n";

        }

    if($i == 1) { echo '<br />' . 'No Rows Found'; } else { echo '<br />' . $i . ' Rows Found'; }
        echo '<textarea>' . $outputTwo . '</textarea>';
        mysql_free_result($result);
    } else {
        echo 'No results';
    }
    mysql_close($cn);
}
?>

HACK AROUND

Replacing the function with this should work. Do not forget to call 'characterListPost()' wherever this is supposed to be output.

function characterListPost() {
    $host = '127.0.0.1';
    $user = 'root';
    $pass = '';
    $data = 'test';

    $cn = mysql_connect($host, $user, $pass) or die(mysql_error());
    mysql_select_db($data, $cn) or die(mysql_error());
    $sql = "SELECT id, ch_position, ch_name, ch_image, ch_description, ch_age, ch_like, ch_dislike FROM characters ORDER BY ch_position";

    $result = mysql_query($sql, $cn) or die(mysql_error());

    $return = "";

    if($result) {

        $previous_season = 0;
        $outputTwo='';
        $i = 1;

        while($row = mysql_fetch_assoc($result)) {

            $outputTwo.= "<div class=\"characterbox\" id=\"div{$i}\">";
            $i++;
            $outputTwo.= "<div class=\"ch_name\">{$row["ch_name"]}</div>";
            $outputTwo.= "<div><image class=\"ch_image\" id=\"ch_image{$row["id"]}\" alt=\"character image TBA\" src=\"{$row["ch_image"]}\" /></div>";
            $outputTwo.= "<div class=\"ch_description\"><p>{$row["ch_description"]}</p></div>";
            $outputTwo.= "<div class=\"ch_age\"><b>Age:</b> {$row["ch_age"]}</div>";
            $outputTwo.= "<div class=\"ch_like\"><b>Like:</b> {$row["ch_like"]}</div>";
            $outputTwo.= "<div class=\"ch_dislike\"><b>Dislike:</b> {$row["ch_dislike"]}</div>";
            $outputTwo.= "<div class=\"Down10px clear\"></div>";
            $outputTwo.= "</div>";

        }

//    if($i == 1) { echo '<br />' . 'No Rows Found'; } else { echo '<br />' . $i . ' Rows Found'; }
        $return = $outputTwo;
        mysql_free_result($result);
//    } else {
//        echo 'No results';
    }
    mysql_close($cn);
    return $return;
}
