mysqli_fetch loop not working

Question

I have a loop inside other loop which is not working, this is the code:

    while($row = mysqli_fetch_array($result))
   {
    echo "<tr>";
    echo "<td>" . $row['rowId'] . "</td>";
    echo "<td>" . $row['startDate'] . "</td>";
    echo "<td>" . $row['eventName'] . "</td>";
    echo "<td>" . $row['betName'] . "</td>";
    $string1 = "SELECT * FROM newCell WHERE rowId ='";
    $string2 = $row['rowId']."'";
    $result2 = $string1.$string2;
    echo "<td>" . $result2 . "</td>";

    while($row2 = mysqli_fetch_array($result2))
    {
        echo "<td>" . $row2['odds'] . "</td>";

        echo "<td>" . $row2['outcomeName'] . "</td>";
    }
   echo "</tr>";
   }

When I query $result2 directly into the BBDD for the first result it shows three results but the code doesn't go in the second LOOP. Why? Any error here?

You're asking it to loop through a `string`, not an `mysqli` object? — MackieeE, Sep 26 '13 at 12:32
`mysqli_fetch_array` works on query result not on query string — bansi, Sep 26 '13 at 12:33

Use:

$query = "SELECT ....";
$result2 = mysqli_query($db, $query);

while($row2 = mysqli_fetch_array($result2))
{
        echo "<td>" . $row2['odds'] . "</td>";

        echo "<td>" . $row2['outcomeName'] . "</td>";
}

I think $result2 should be output of mysqli_query not just merely query. Talking in analogous to MySQL.

Probably you should have something like this

$result2 = mysqli_query($result2);

Try This

<?php
while($row = mysqli_fetch_array($result))
   {
    echo "<tr>";
    echo "<td>" . $row['rowId'] . "</td>";
    echo "<td>" . $row['startDate'] . "</td>";
    echo "<td>" . $row['eventName'] . "</td>";
    echo "<td>" . $row['betName'] . "</td>";
    $string1 = "SELECT * FROM newCell WHERE rowId ='";
    $string2 = $row['rowId']."'";
    $result2 = $string1.$string2;
    echo "<td>" . $result2 . "</td>";
    $results = mysqli_query($db,$result2);
    while($row2 = mysqli_fetch_array($results))
    {
        echo "<td>" . $row2['odds'] . "</td>";

        echo "<td>" . $row['outcomeName'] . "</td>";
    }
   echo "</tr>";
   }
  ?>

  while($row = mysqli_fetch_array($result))
   {
    echo "<tr>";
    echo "<td>" . $row['rowId'] . "</td>";
    echo "<td>" . $row['startDate'] . "</td>";
    echo "<td>" . $row['eventName'] . "</td>";
    echo "<td>" . $row['betName'] . "</td>";
    $string1 = "SELECT * FROM newCell WHERE rowId ='";
    $string2 = $row['rowId']."'";
    $result2 = $string1.$string2;
    echo "<td>" . $result2 . "</td>";

    $result2 = mysqli_query($connection, $result2);

    while($row2 = mysqli_fetch_array($result2))
    {
        echo "<td>" . $row2['odds'] . "</td>";

        echo "<td>" . $row2['outcomeName'] . "</td>";
    }
   echo "</tr>";
   }

Before fetching data execute mysql query using mysqli_query() function then run mysqli_fetch_array(). It would be good if you count result as $count = mysqli_num_rows($query) and manage your code with if... else .
